Endoscopic bariatric therapies are emerging as valuable alternatives for patients with doubts about bariatric surgery or ineligible for it. Endoscopic sleeve gastroplasty(ESG), a relatively novel technique of endoscopic bariatric therapies, has gained standing in the past few years. The safety, feasibility, repeatability, and potential for reversibility of ESG have been proven by multicenter studies. Compared to other weight loss strategies, current evidence demonstrates that ESG offers satisfactory efficacy in weight loss. Even though it is inferior to laparoscopic sleeve gastrectomy, it has lower risks of adverse events than surgical interventions and intragastric balloon within oneyear follow-up. Furthermore, ESG may be the ideal weight control strategy for patients who have poor adherence to behavioral interventions. Even so, trends in decreased weight loss effect over time, post-procedure weight regain, postprocedure gut hormone alteration, and possible effects of race and ethnicity on ESG still remain undetermined due to very limited reports and very short followups. Further clinical trials are required to validate and answer these questions.展开更多

The primary outcome was total body weight loss(TBWL) at 12 mo. Secondary outcomes included changes in TBWL, excess weight loss(EWL) and BMI at various time points up to 36 mo, clinical responder rates at 12 and 24 mo, and comorbidity improvement. Safety outcomes were reported through the study duration. One-way ANOVA test was performed with multiple Tukey pairwise comparisons for TBWL, EWL, and BMI over the study duration.RESULTS 404 consecutive patients(78.5% female, mean age 42.9 years, mean BMI 44.8 ± 4.7 kg/m2) were enrolled. ESGs were performed using an average of 7 sutures, over 42 ± 9 min, and with 100% technical success. TBWL was 20.9 ± 6.2% at 12 mo, 20.5 ± 6.9% at 24 mo, and 20.3 ± 9.5% at 36 mo. EWL was 49.6 ± 15.1% at 12 mo, 49.4 ± 16.7% at 24 mo, and 47.1 ± 23.5% at 36 mo. There was no difference in TBWL at 12, 15, 24, and 36 mo from ESG. TBWL exceeding 10%, 15%, and 20% was achieved by 96.7%, 87.4%, and 55.6% of the cohort at 12 mo, respectively. Of the cohort with the relevant comorbidity at time of ESG, 66.1% had improvement in hypertension, 61.7% had improvement in type Ⅱ diabetes, and 45.1% had improvement in hyperlipidemia over study duration. There was one instance of dehydration requiring hospitalization(0.2% serious adverse event rate).CONCLUSION When combined with longitudinal nutritional support, ESG induces effective and durable weight loss in adults with class Ⅲ obesity, with improvement in comorbidities and an acceptable safety profile.展开更多

As a result,there is a drive to develop less invasive therapies to combat obesity. Endoscopic bariatric therapies(EBT) for weight loss are important since they are more effective than pharmacological treatments and lifestyle changes and present lower adverse event rates compared to bariatric surgery. Endoscopic sleeve gastroplasty(ESG) is a minimally invasive EBT that involves remodeling of the greater curvature. ESG demonstrated favorable outcomes in several centers,with up to 20.9% total body weight loss and 60.4% excess weight loss(EWL) on 2-year follow-up,with a low rate of severe adverse events(SAE). As such,it could be considered safe and effective in light of ASGE/ASMBS thresholds of > 25% EWL and ≤ 5% SAE,although there are no comparative trials to support this. Additionally,ESG showed improvement in diabetes mellitus type 2,hypertension,and other obesity-related comorbidities. As this procedure continues to develop there are several areas that can be addressed to improve outcomes,including device improvements,technique standardization,patient selection,personalized medicine,combination therapies,and training standardization. In this editorial we discuss the origins of the ESG,current data,and future developments.展开更多

Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent c SG and 115 patients underwent c RYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss(%EWL) after Re-VBG, cS G and cR YGB was, respectively, 45%, 57% and 72%. Eighteen patients(11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Rouxen-Y gastric bypass seems feasible as a revision for a failed VBG.展开更多

Though popular in earlier decades, the Vertical Banded Gastroplasty (VBG) is no longer a staple procedure in the United States. It has been supplanted by the Roux-en-Y gastric bypass (RYGBP) and the laparoscopic adjustable gastric band (LAGB) as the most commonly performed bariatric procedures. However, there are many patients who have previously undergone VBGs, and may present with associated complications. We present a case of a gastric obstruction caused by a bezoar in a patient who had a VBG fifteen years prior to presentation.展开更多

So far, indications for OTSC application are hemostasis of pri-mary or post-interventional bleeding, closure of iatrogenic full-thickness or covered perforations. Recently closure of gastrointestinal tract fistulas using this device has been described. Objective: In this case, we describe the successful endoscopic closure, using the OTSC system, of a gastrogastric fistula due to staple line disruption in patient with vertical banded gastroplasty. Conclusion: Endoscopic application of the OTSC device is safe and effective for the treatment of a staple line disruption.展开更多

Their ability to facilitate weight loss is largely tied to influences on appetite through perturbations of gastric emptying and accommodation. As these tools gain traction in obesity therapy, their physiologic underpinnings require exploration, which may enhance efficacy, tolerance, and patient-tailored care.Methods: We prospectively assessed consecutive subjects with fluid-filled intragastric balloons (IGBs) (n = 18) placed between October 2016 and June 2017 or underwent endoscopic sleeve gastroplasty (ESG) (n = 23) from March 2018 to June 2018. Patients underwent physiologic appraisal at 3 months with13C-spirulina-based gastric emptying breath test to determine time to half emptying (T50), as well as maximum tolerated volume (MTV) of a standard nutrient drink test. Changes in T50 and MTV at 3 months were compared with percent total body weight loss (%TBWL) at 3 and 6 months using best-fit linear regression.Results: The change in T50 at 3 months correlated with %TBWL at 3 months for IGB (P = 0.01) and ESG (P = 0.01) but with greater impact on %TBWL in IGB compared to ESG (R2 = 0.42vs. 0.26). Change in T50 at 3 months was predictive of weight loss at 6 months for IGB (P = 0.01) but not ESG (P = 0.11). ESG was associated with greater decrease in MTV compared to IGB (340.25 ± 297.97 mLvs. 183.00 ± 217.13 mL,P = 0.08), indicting an enhanced effect on satiation through decreased gastric accommodation. Changes in MTV at 3 months did not correlate with %TBWL for either IGB (P = 0.26) or ESG (P = 0.49) but trended toward significance for predicting %TBWL at 6 months for ESG (P = 0.06) but not IGB (P = 0.19).Conclusion: IGB and ESG both induce weight loss but likely through distinct gastric motor function phenotypes, and gastric emptying may predict future weight loss in patients with IGB.展开更多

Within each topic,the content will progress as follows: "lessons learned", "technical considerations"and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years.Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver,pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease(GERD), achalasia, esophageal diverticula, Barrett's esophagus(BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors.For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy(POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique(Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection(ESD)which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies(radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy.Importantly, in regard to early gastric cancer and submucosal tumors(SMTs) of the stomach, ESD and full thickness resection(FTR) can excise these lesions enbloc and endoscopic suturing is now used to close large defects and perforations.For treatment of patients with malignant gastric outlet obstruction(GOO),endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty(ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound(EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.展开更多

METHODS: A group of 31 patients with thoracic and abdominal esophageal cancer underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube. In the region elected for anastomosis, a transverse myotomy of the esophagus was carried out around the entire circumference of the esophagus. Afterwards, a 4-cm long segment of esophagus was invaginated into the stomach and anastomosed to the anterior and the posterior walls. RESULTS: Postoperative minor complications occurred in 22 (70.9%) patients. Four (12.9%) patients had serious complications that led to death. The discharge of saliva was at a lower region, while attempting to leave the anastomosis site out of the alimentary transit. Three (9.7%) patients had fistula at the esophagogastric anastomosis, with minimal leakage of air or saliva and with mild clinical repercussions. No patients had esophago- gastric fistula with intense saliva leakage from either the cervical incision or the thoracic drain. Fibrotic stenosis of anastomoses occurred in seven (22.6%) patients. All these patients obtained relief from their dysphagia with endoscopic dilatation of the anastomosis.CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula with mild clinical repercussions.展开更多

This rise increases the occurrence of, risks of, and costs of treating obesity-related medical conditions. Diet and activity programs are largely inadequate for the long-term treatment of medically-complicated obesity. Physicians who deliver gastrointestinal care after completing traditional training programs, including gastroenterologists and general surgeons, are not uniformly trained in or familiar with available bariatric care. It is certain that gastrointestinal physicians will incorporate new endoscopic methods into their practice for the treatment of individuals with medically-complicated obesity, although the longterm impact of these endoscopic techniques remains under investigation. It is presently unclear whether gastrointestinal physicians will be able to provide or coordinate important allied services in bariatric surgery, endocrinology, nutrition, psychological evaluation and support, and social work. Obtaining longitudinal results examining the effectiveness of this ad hoc approach will likely be difficult, based on prior experience with other endoscopic measures, such as the adenoma detection rates from screening colonoscopy. As a longterm approach, development of a specific curriculum incorporating one year of subspecialty training in bariatrics to the present training of gastrointestinal fellows needs to be reconsidered. This approach should be facilitated by gastrointestinal trainees' prior residency training in subspecialties that provide care for individuals with medical complications of obesity, including endocrinology, cardiology, nephrology, and neurology. Such training could incorporate additional rotations with collaborating providers in bariatric surgery, nutrition, and psychiatry. Since such training would be provided in accredited programs, longitudinal studies could be developed to examine the potential impact on accepted measures of care, such as complication rates, outcomes, and costs, in individuals with medically-complicated obesity.展开更多

The availability of commercial, clinical, and operative therapies for weight management have not been effective at a societal level. Endoscopic bariatric therapy is gaining acceptance as more effective than diet and lifestyle measures, and less invasive than bariatric surgery. Various endoscopic therapies are analogues of the restrictive or bypass components of bariatric surgery, utilizing gastric remodeling or intestinal anastomosis to achieve proven weight loss and metabolic benefits. Others, such as aspiration therapy, employnovel mechanisms of action. Intragastric balloons have recently been approved by the United States Food and Drug Administration, and a number of other technologies have completed large multicenter trials(such as AspireA ssist aspiration therapy and Primary Obesity Surgery Endolumenal). Endoscopic sleeve gastroplasty and transoral outlet reduction for endoscopic revision of gastric bypass have proven safe and effective in a number of studies. As devices are approved for use, data will continue to accumulate for safety, effectiveness, and cost effectiveness. Bariatric endoscopists should be prepared to appropriately target and apply various endoscopic bariatric therapies in the context of a comprehensive long-term weight management program.展开更多

文摘BACKGROUND Obesity impacts 42%of United States adults and results in an estimated economic burden of nearly 1.4 trillion dollars annually.Endoscopic sleeve gastroplasty(ESG)is a United States Food and Drug Administration authorized procedure with an excellent safety,efficacy,and durability profile.The cost-effectiveness of ESG compared to lifestyle modification(LM)in real-world patients with class I-III obesity represents a critical knowledge gap.AIM To approximate the cost-effectiveness of ESG vs LM using a real-world dataset of 860 United States adults with class I-III obesity undergoing ESG.METHODS A 6-state Markov model was employed,including healthy weight,overweight,class I-III obesity,and death.The LM control group was built using transition states previously described in the literature,supplemented by expert opinion.Cycles lasted six-months in the model’s first year and twelve-months thereafter.Existing literature informed approximations of each health state utility,adverse event disutility,and incidence of obesity-associated comorbidities.One-way sensitivity and probabilistic sensitivity analyses were performed.RESULTS The base-case incremental cost-effectiveness ratio(ICER)for ESG vs LM was 5904 dollars per quality-adjusted life year(QALY).In a one-way sensitivity analysis,the utilities assigned to the three obesity classes most greatly influenced the ICER.Probabilistic sensitivity analysis estimated an increase in upper-bound ICER of 8038 dollars per QALY,well under the generally cited United States willingness to pay ratio of 100000 dollars per QALY.CONCLUSION The results of this model support that ESG is overwhelmingly cost-effective compared to LM across all obesity classes.Payors should consider expanding coverage for their members.
文摘Obesity is a major global health issue,contributing to numerous comorbidities such as type 2 diabetes mellitus,hypertension,and cardiovascular diseases.While bariatric surgery remains the gold standard for treating severe obesity,its invasive nature has led to the development of minimally invasive alternatives.Endoscopic sleeve gastroplasty(ESG)is a promising,minimally invasive procedure for weight loss,offering significant weight reduction without the need for surgical incisions.This editorial evaluates the efficacy and safety of ESG,highlighting its weight loss outcomes,safety profile,and comparison with other bariatric procedures,including intragastric balloon,laparoscopic sleeve gastrectomy,and robotic sleeve gastrectomy.ESG has shown substantial weight loss with a mean total weight loss ranging from 15.03%to 17.51%at 12 months and sustained weight reduction over 36 months.The safety profile is favorable,with low rates of serious adverse events and minimal complications compared to surgical alternatives.ESG is particularly suited for patients with mild to moderate obesity or those not eligible for surgical options.However,further long-term studies and standardized protocols are needed to refine patient selection and optimize treatment outcomes.
文摘Bariatric surgeries have been demonstrated to be safe and effective treatment options for morbid obesity patients, but operative risks and high health care costs limit their clinical application. Endoscopic bariatric therapies are emerging as valuable alternatives for patients with doubts about bariatric surgery or ineligible for it. Endoscopic sleeve gastroplasty(ESG), a relatively novel technique of endoscopic bariatric therapies, has gained standing in the past few years. The safety, feasibility, repeatability, and potential for reversibility of ESG have been proven by multicenter studies. Compared to other weight loss strategies, current evidence demonstrates that ESG offers satisfactory efficacy in weight loss. Even though it is inferior to laparoscopic sleeve gastrectomy, it has lower risks of adverse events than surgical interventions and intragastric balloon within oneyear follow-up. Furthermore, ESG may be the ideal weight control strategy for patients who have poor adherence to behavioral interventions. Even so, trends in decreased weight loss effect over time, post-procedure weight regain, postprocedure gut hormone alteration, and possible effects of race and ethnicity on ESG still remain undetermined due to very limited reports and very short followups. Further clinical trials are required to validate and answer these questions.
文摘BACKGROUND Endoscopic sleeve gastroplasty(ESG) is an effective therapy for class Ⅰ-Ⅱ obesity, but there are knowledge gaps in the published literature about its implementation in patients with class Ⅲ obesity [body mass index(BMI) ≥ 40 kg/m2].AIM To evaluate the safety, clinical efficacy, and durability of ESG in adults with class Ⅲ obesity.METHODS This was a retrospective cohort study that used prospectively collected data on adults with BMI ≥ 40 kg/m2who underwent ESG and longitudinal lifestyle counseling at two centers with expertise in endobariatric therapies from May 2018-March 2022. The primary outcome was total body weight loss(TBWL) at 12 mo. Secondary outcomes included changes in TBWL, excess weight loss(EWL) and BMI at various time points up to 36 mo, clinical responder rates at 12 and 24 mo, and comorbidity improvement. Safety outcomes were reported through the study duration. One-way ANOVA test was performed with multiple Tukey pairwise comparisons for TBWL, EWL, and BMI over the study duration.RESULTS 404 consecutive patients(78.5% female, mean age 42.9 years, mean BMI 44.8 ± 4.7 kg/m2) were enrolled. ESGs were performed using an average of 7 sutures, over 42 ± 9 min, and with 100% technical success. TBWL was 20.9 ± 6.2% at 12 mo, 20.5 ± 6.9% at 24 mo, and 20.3 ± 9.5% at 36 mo. EWL was 49.6 ± 15.1% at 12 mo, 49.4 ± 16.7% at 24 mo, and 47.1 ± 23.5% at 36 mo. There was no difference in TBWL at 12, 15, 24, and 36 mo from ESG. TBWL exceeding 10%, 15%, and 20% was achieved by 96.7%, 87.4%, and 55.6% of the cohort at 12 mo, respectively. Of the cohort with the relevant comorbidity at time of ESG, 66.1% had improvement in hypertension, 61.7% had improvement in type Ⅱ diabetes, and 45.1% had improvement in hyperlipidemia over study duration. There was one instance of dehydration requiring hospitalization(0.2% serious adverse event rate).CONCLUSION When combined with longitudinal nutritional support, ESG induces effective and durable weight loss in adults with class Ⅲ obesity, with improvement in comorbidities and an acceptable safety profile.
文摘The most effective and durable treatment for obesity is bariatric surgery.However,less than 2% of eligible patients who fulfill the criteria for bariatric surgery undergo the procedure. As a result,there is a drive to develop less invasive therapies to combat obesity. Endoscopic bariatric therapies(EBT) for weight loss are important since they are more effective than pharmacological treatments and lifestyle changes and present lower adverse event rates compared to bariatric surgery. Endoscopic sleeve gastroplasty(ESG) is a minimally invasive EBT that involves remodeling of the greater curvature. ESG demonstrated favorable outcomes in several centers,with up to 20.9% total body weight loss and 60.4% excess weight loss(EWL) on 2-year follow-up,with a low rate of severe adverse events(SAE). As such,it could be considered safe and effective in light of ASGE/ASMBS thresholds of > 25% EWL and ≤ 5% SAE,although there are no comparative trials to support this. Additionally,ESG showed improvement in diabetes mellitus type 2,hypertension,and other obesity-related comorbidities. As this procedure continues to develop there are several areas that can be addressed to improve outcomes,including device improvements,technique standardization,patient selection,personalized medicine,combination therapies,and training standardization. In this editorial we discuss the origins of the ESG,current data,and future developments.
文摘AIM: To compare the results after revision of primary vertical banded gastroplasty(Re-VBG) and conversion to sleeve gastrectomy(cS G) or gastric bypass(cR YGB).METHODS: In this retrospective single-center study, all patients with a failed VBG who underwent revisional surgery were included. Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent c SG and 115 patients underwent c RYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss(%EWL) after Re-VBG, cS G and cR YGB was, respectively, 45%, 57% and 72%. Eighteen patients(11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Rouxen-Y gastric bypass seems feasible as a revision for a failed VBG.
文摘Gastric bezoars are uncommon in the bariatric surgery population. Though popular in earlier decades, the Vertical Banded Gastroplasty (VBG) is no longer a staple procedure in the United States. It has been supplanted by the Roux-en-Y gastric bypass (RYGBP) and the laparoscopic adjustable gastric band (LAGB) as the most commonly performed bariatric procedures. However, there are many patients who have previously undergone VBGs, and may present with associated complications. We present a case of a gastric obstruction caused by a bezoar in a patient who had a VBG fifteen years prior to presentation.
文摘Endoscopic sleeve gastroplasty(ESG)is a minimally invasive procedure used in the treatment of obesity,with a complication rate of less than 2%of cases.There have been only two reported cases worldwide of gallbladder injuries as a major complication of ESG.CASE SUMMARY We present the case of a 34-year-old patient who developed a complication after ESG.The patient experienced epigastric and right hypochondrium pain 12 h after the procedure,and a positive Murphy’s sign was identified on physical examination.Laboratory results showed a leukocyte count of 17×10^(3)/μL,and computed tomography indicated the presence of free fluid in the pelvic cavity and perihepatic recesses as well as a possible suture in the wall of the Hartmann’s pouch toward the anterior surface of the stomach.A diagnostic laparoscopy was performed,revealing plication of the Hartmann’s pouch wall to the anterior stomach wall.Laparoscopic cholecystectomy and lavage were carried out.The patient had a stable recovery and was discharged 72 h after surgery,tolerating oral intake.CONCLUSION Gallbladder plication should be suspected if signs and symptoms consistent with acute cholecystitis occur after ESG.
文摘Background: scope-clip (OTSC;Ovesco Endoscopy GmbH, Tuebingen, Germany) system is a newly designed method for the mechanical compression of large areas in the gastrointestinal tract. So far, indications for OTSC application are hemostasis of pri-mary or post-interventional bleeding, closure of iatrogenic full-thickness or covered perforations. Recently closure of gastrointestinal tract fistulas using this device has been described. Objective: In this case, we describe the successful endoscopic closure, using the OTSC system, of a gastrogastric fistula due to staple line disruption in patient with vertical banded gastroplasty. Conclusion: Endoscopic application of the OTSC device is safe and effective for the treatment of a staple line disruption.
文摘Background: Endoscopic bariatric therapies can help address widening management gaps in obesity. Their ability to facilitate weight loss is largely tied to influences on appetite through perturbations of gastric emptying and accommodation. As these tools gain traction in obesity therapy, their physiologic underpinnings require exploration, which may enhance efficacy, tolerance, and patient-tailored care.Methods: We prospectively assessed consecutive subjects with fluid-filled intragastric balloons (IGBs) (n = 18) placed between October 2016 and June 2017 or underwent endoscopic sleeve gastroplasty (ESG) (n = 23) from March 2018 to June 2018. Patients underwent physiologic appraisal at 3 months with13C-spirulina-based gastric emptying breath test to determine time to half emptying (T50), as well as maximum tolerated volume (MTV) of a standard nutrient drink test. Changes in T50 and MTV at 3 months were compared with percent total body weight loss (%TBWL) at 3 and 6 months using best-fit linear regression.Results: The change in T50 at 3 months correlated with %TBWL at 3 months for IGB (P = 0.01) and ESG (P = 0.01) but with greater impact on %TBWL in IGB compared to ESG (R2 = 0.42vs. 0.26). Change in T50 at 3 months was predictive of weight loss at 6 months for IGB (P = 0.01) but not ESG (P = 0.11). ESG was associated with greater decrease in MTV compared to IGB (340.25 ± 297.97 mLvs. 183.00 ± 217.13 mL,P = 0.08), indicting an enhanced effect on satiation through decreased gastric accommodation. Changes in MTV at 3 months did not correlate with %TBWL for either IGB (P = 0.26) or ESG (P = 0.49) but trended toward significance for predicting %TBWL at 6 months for ESG (P = 0.06) but not IGB (P = 0.19).Conclusion: IGB and ESG both induce weight loss but likely through distinct gastric motor function phenotypes, and gastric emptying may predict future weight loss in patients with IGB.
文摘Endoscopic bariatrics has emerged as a minimally invasive alternative to traditional bariatric procedures.Over the last decade,significant progress in endoscopic techniques and technologies has improved the safety,efficacy,and accessibility of these procedures.Current methods,such as intragastric balloons,endoscopic sleeve gastroplasty,and endoscopic-assisted gastrojejunostomy,have promoted weight loss,improving the metabolic health of obese individuals,with emerging evidence suggesting that their combination with pharmacological agents could further maximize their benefit.Emerging technologies,such as robotic-assisted endoscopic devices,advanced imaging systems,and biodegradable implants,could enhance procedural precision,minimize complications,and provide more personalized treatment options.In contrast,novel approaches such as microbiome modulation and tissue regeneration could have an adjunct role in improving patient outcomes.This review provides a brief overview of the current status of endoscopic bariatrics,highlighting the most common procedures and emerging technologies.It also discusses the challenges and future directions for the field,emphasizing the importance of multidisciplinary collaboration,patient selection,and research priorities to establish the long-term benefit and effectiveness of the available endoscopic bariatric interventions.
文摘Metabolic dysfunction-associated steatohepatitis(MASH)has become a leading indication for liver transplantation.Bariatric surgery is a proven intervention for weight loss and metabolic improvement in MASH but concerns over surgical risk in patients with advanced liver disease has expanded interest in endoscopic sleeve gastroplasty(ESG)as a less invasive alternative.This review examine the efficacy,safety,and metabolic impact of ESG vs traditional bariatric surgery(Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy)in patients with MASH,with and without cirrhosis.We analyze current evidence on weight loss outcomes,histologic and biochemical improvements in MASH,resolution of metabolic syndrome,and perioperative risks associated with these procedures.Special attention is given to the feasibility of ESG in compensated cirrhosis(Child-Pugh A/B)and the potential role of bariatric interventions in delaying or avoiding liver transplantation.As the prevalence of MASH-related cirrhosis rises,refining bariatric strategies for this high-risk population is imperative.ESG may offer a lower procedural risk profile,but current data are largely limited to small,observational studies with short-term follow-up.A tailored,multidisciplinary approach is essential to optimize weight management and liver health in MASH patients,with future studies needed to clarify the long-term efficacy and safety of ESG in MASH.

文摘Obesity is a chronic,multifactorial disease closely linked to a spectrum of cardiometabolic disorders,with its global prevalence rising at an alarming rate.In recent years,minimally invasive,safe,and effective endoscopic bariatric therapies have gained significant attention as alternatives to conventional surgical interventions.This review provides a comprehensive overview of various endoscopic weight-loss procedures,evaluating their advantages and limitations in comparison to surgical approaches to assist clinicians in optimizing patientspecific treatment strategies.Endoscopic bariatric therapies,including intragastric balloons,duodenal-jejunal bypass sleeves,endoscopic sleeve gastroplasty,gastric remodeling procedures,and interventions aimed at delaying gastric emptying are systematically reviewed.The efficacy,safety profiles,and clinical applicability are all synthesized.Endoscopic bariatric therapies exhibit distinct advantages and limitations,with varying indications and contraindications.As part of a multidisciplinary approach to obesity management,these procedures should be integrated with lifestyle modifications and nutritional counseling to maximize therapeutic benefits.Future research should focus on the long-term efficacy,safety,and patient-reported outcomes to refine clinical practice and optimize the role of endoscopic interventions in obesity treatment.
文摘In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic,the content will progress as follows: "lessons learned", "technical considerations"and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years.Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver,pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease(GERD), achalasia, esophageal diverticula, Barrett's esophagus(BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors.For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy(POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique(Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection(ESD)which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies(radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy.Importantly, in regard to early gastric cancer and submucosal tumors(SMTs) of the stomach, ESD and full thickness resection(FTR) can excise these lesions enbloc and endoscopic suturing is now used to close large defects and perforations.For treatment of patients with malignant gastric outlet obstruction(GOO),endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty(ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound(EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.

文摘AIM: To present a new technique of cervical esophagogastric anastomosis to reduce the frequency of fistula formation. METHODS: A group of 31 patients with thoracic and abdominal esophageal cancer underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube. In the region elected for anastomosis, a transverse myotomy of the esophagus was carried out around the entire circumference of the esophagus. Afterwards, a 4-cm long segment of esophagus was invaginated into the stomach and anastomosed to the anterior and the posterior walls. RESULTS: Postoperative minor complications occurred in 22 (70.9%) patients. Four (12.9%) patients had serious complications that led to death. The discharge of saliva was at a lower region, while attempting to leave the anastomosis site out of the alimentary transit. Three (9.7%) patients had fistula at the esophagogastric anastomosis, with minimal leakage of air or saliva and with mild clinical repercussions. No patients had esophago- gastric fistula with intense saliva leakage from either the cervical incision or the thoracic drain. Fibrotic stenosis of anastomoses occurred in seven (22.6%) patients. All these patients obtained relief from their dysphagia with endoscopic dilatation of the anastomosis.CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula with mild clinical repercussions.
文摘A world-wide rise in the prevalence of obesity continues. This rise increases the occurrence of, risks of, and costs of treating obesity-related medical conditions. Diet and activity programs are largely inadequate for the long-term treatment of medically-complicated obesity. Physicians who deliver gastrointestinal care after completing traditional training programs, including gastroenterologists and general surgeons, are not uniformly trained in or familiar with available bariatric care. It is certain that gastrointestinal physicians will incorporate new endoscopic methods into their practice for the treatment of individuals with medically-complicated obesity, although the longterm impact of these endoscopic techniques remains under investigation. It is presently unclear whether gastrointestinal physicians will be able to provide or coordinate important allied services in bariatric surgery, endocrinology, nutrition, psychological evaluation and support, and social work. Obtaining longitudinal results examining the effectiveness of this ad hoc approach will likely be difficult, based on prior experience with other endoscopic measures, such as the adenoma detection rates from screening colonoscopy. As a longterm approach, development of a specific curriculum incorporating one year of subspecialty training in bariatrics to the present training of gastrointestinal fellows needs to be reconsidered. This approach should be facilitated by gastrointestinal trainees' prior residency training in subspecialties that provide care for individuals with medical complications of obesity, including endocrinology, cardiology, nephrology, and neurology. Such training could incorporate additional rotations with collaborating providers in bariatric surgery, nutrition, and psychiatry. Since such training would be provided in accredited programs, longitudinal studies could be developed to examine the potential impact on accepted measures of care, such as complication rates, outcomes, and costs, in individuals with medically-complicated obesity.
文摘The prevalence of obesity continues to rise,and along with it comes a multitude of health-related consequences.The healthcare community has consistently struggled with providing treatment options to obese patients,in part due to the reluctance of patients in pursuing the more effective(yet invasive)surgical approaches such as sleeve gastrectomy and Rou-en-Y gastric bypass.On the other hand,the less invasive approach such as lifestyle/behavioral interventions and pharmacotherapy(Orlistat,Phenteramine,Phentermine/Topiramate,Locaserin,Naltrexon/Buproprion,and Liraglutide)have very limited efficacy,especially in the morbidly obese patients.Despite our best efforts,the epidemic of obesity continues to rise and pose enormous costs on our healthcare system and society.Bariatric endoscopy is an evolving field generated to combat this epidemic through minimally invasive techniques.These procedures can be performed in an ambulatory setting,are potentially reversible,repeatable,and pose less complications than their invasive surgical counterparts.These modalities are designed to alter gut metabolism by means of space occupation,malabsorption,or restriction.In this review we will discuss different bariatric endoscopic options(such as intragastric balloons,endoscopic sleeve gastroplasty,endoscopic aspiration therapies and gastrointestinal bypass sleeves),their advantages and disadvantages,and suggest a new paradigm where providers may start incorporating this modality in their treatment approach for obese patients.
文摘Weight regain following primary bariatric surgery occurs in a significant proportion of patients and is attributed to epidemiological,anatomical and metabolic factors.Surgical revision of these patients has significant risks and limited benefits.Endoscopic revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective,safe,less invasive and even reproducible treatment.We herein discuss the indication,selection and feasibility of different endoscopic techniques that could be used in the management of weight regain following primary bariatric surgery.Future research could optimize a personalized approach not only in the endoscopic management but also in combination with other therapeutic modalities for weight regain after bariatric surgery.
文摘Obesity and its comorbidities- including diabetes and obstructive sleep apnea- have taken a large and increasing toll on the United States and the rest of the world. The availability of commercial, clinical, and operative therapies for weight management have not been effective at a societal level. Endoscopic bariatric therapy is gaining acceptance as more effective than diet and lifestyle measures, and less invasive than bariatric surgery. Various endoscopic therapies are analogues of the restrictive or bypass components of bariatric surgery, utilizing gastric remodeling or intestinal anastomosis to achieve proven weight loss and metabolic benefits. Others, such as aspiration therapy, employnovel mechanisms of action. Intragastric balloons have recently been approved by the United States Food and Drug Administration, and a number of other technologies have completed large multicenter trials(such as AspireA ssist aspiration therapy and Primary Obesity Surgery Endolumenal). Endoscopic sleeve gastroplasty and transoral outlet reduction for endoscopic revision of gastric bypass have proven safe and effective in a number of studies. As devices are approved for use, data will continue to accumulate for safety, effectiveness, and cost effectiveness. Bariatric endoscopists should be prepared to appropriately target and apply various endoscopic bariatric therapies in the context of a comprehensive long-term weight management program.
文摘In this editorial,we reviewed the article by Li et al.We aimed to explore various perspectives to further mitigate the risk factors for postoperative nausea and vomiting(PONV),which could significantly reduce its incidence and related post-operative complications.PONV is highly prevalent among patients undergoing bariatric surgery,yet there are relatively few related studies.Currently,the main-stream bariatric surgery methods include laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy.Despite the effectiveness of surgery in helping patients lose weight,postoperative PONV may occur,potentially leading to various complications(such as aspiration and wound dehiscence).A retro-spective study by Li et al has compared the impact of different operative positions during laparoscopic sleeve gastroplasty on the incidence of PONV,providing new insights into the clinical practice aimed at reducing PONV incidence and thereby improving patient’s postoperative experience.
