Bariatric surgery, including sleeve gastrectomy (SG), is a proven treatment for morbid obesity, offering substantial weight loss and resolution of comorbidities. However, post-surgical complications, particularly anorectal disorders such as hemorrhoids and anal fissures, remain underexplored, especially in Saudi Arabia. This retrospective cohort study aimed to assess the prevalence, risk factors, and impact of anal complications following SG at Almoosa Specialist Hospital in Alhassa, Saudi Arabia. A total of 205 patients who underwent SG between January 2020 and December 2021 were surveyed, with 148 eligible participants included in the final analysis. Results indicated that 8.8% of patients experienced anal complications, with anal fissures (53.8%) and hemorrhoids (38.5%) being the most common. These complications typically occurred 2 - 6 months post-surgery. Lifestyle factors such as physical activity and fluid intake were found to significantly reduce the likelihood of anal issues. Moreover, 69.2% of patients with anal problems reported a negative impact on their quality of life. The study highlights the importance of targeted post-operative care, including lifestyle modifications, to mitigate the impact of anal complications. The findings suggest that ongoing education and comprehensive support for bariatric surgery patients, particularly regarding physical activity and hydration, are critical for improving long-term health outcomes. Further research is needed to explore the long-term progression of anal complications and effective interventions for enhancing patient satisfaction and quality of life.展开更多

Background: Sleeve gastrectomy (SG) is one of the most frequently performed bariatric operations worldwide. Nevertheless, weight regain and gastroesophageal reflux disease (GERD) have been consistently demonstrated, in association with this technique, which may require a revisional procedure. RYGB is an option in such a situation but, implies in gastrointestinal exclusions, which represents a shortcoming of this revision. Surpassing this inconvenient would be of great value for the patients. Methods: We describe herein two cases of SG revision for weight regain and GERD, with a follow-up of one year. Gastroesophageal reflux disease was evaluated by validated questionnaire, upper endoscopy, seriography, high resolution manometry (HRM) and impedance pHmetry (I-pHmetry), in the pre and postoperative periods. A re-Sleeve Gastrectomy with antrojejunal anastomosis was done in both cases, after informed consents. The Latarjet nerves were transected in one case, due to a bleeding in the left gastric vessels and a truncal vagotomy was required in the other, to appropriately treat an associated hiatal hernia. Results: In the postoperative evaluation it was observed a pyloric spasm in both cases, during seriography and endoscopy, kept until the one-year follow-up. There was unidirectional contrast flow to the gastrointestinal anastomosis, filling the jejunal limb, in radiologic contrast study. No contrast passed through the pylorus. Nonetheless, the duodenum was kept endoscopically accessible. In the one-year evaluation, weight loss was adequate and GERD resolution was obtained in both cases, confirmed by endoscopic and functional esophageal assessment, together with symptoms questionnaire. Conclusion: The association of Latarjet nerves sectioning or truncal vagotomy with re-sleeve gastrectomy plus gastrointestinal anastomosis (antrojejunal), in a revision for a failed sleeve, can represent a technical approach, to reproduce RYGB results, without exclusions and with duodenum endoscopic accessibility maintenance. It maybe could be applied for primary surgeries. Additional studies are necessary to confirm this hypothesis.展开更多

We investigated whether a small gap bio-sleeve suture with different inner diameters at both ends can be used to repair a 2-mm tibial nerve defect by proximal transposition of the common peroneal nerve in rats and compared the results with the repair seen after epineurial neurorrhaphy. Three months after surgery, neurological function, nerve regeneration, and recovery of nerve innervation muscle were assessed using the tibial nerve function index, neuroelectrophysiological testing, muscle biomechanics and wet weight measurement, osmic acid staining, and hematoxylin-eosin staining. There was no obvious inflammatory reaction and neuroma formation in the tibial nerve after repair by the small gap bio-sleeve suture with different inner diameters at both ends. The conduction velocity, muscle strength, wet muscle weight, cross-sectional area of muscle fibers, and the number of new myelinated nerve fibers in the biosleeve suture group were similar to those in the epineurial neurorrhaphy group. Our findings indicate that small gap bio-sleeve suture with different inner diameters at both ends can achieve surgical suture between nerves of different diameters and promote regeneration and functional recovery of injured peripheral nerves.展开更多

Method： From March 1995 to October 2010, double sleeve Iobectomy of the bronchus and the pulmonary artery was performed in 45 cases with central lung cancer that involved the bronchial opening of an upper lobe of the lungs or the main bronchus and＇pulmonary artery but didn＇t involve any lower lobes. Among them, left upper Iobectomy was performed in 37 cases, right medium-upper Iobectomy was performed in 6 cases and right upper Iobectomy was performed in 2 cases. Results： Postoperative complications were found in 12 cases. Among them, 3 cases were arrhythmia, 1 case was acute heart failure, 6 cases were obstructive pneumo-nia and pulmonary atelectasis, 2 cases were bronchial anastomotic fistula. Two cases died of cerebral infarction and massive hemoptysis respectively. Thirty-one cases were squamous carcinoma, 7 cases were adenocarcinoma, 4 cases were small cell lung cancer, 1 case was adenosquamous carcinoma, 1 case was sarcomatoid carcinomas, 1 case was mucinous adeno- carcinoma. Ten cases were T3NOM0, 11 cases were T3N 1M0, 17 cases were T3N2M0, 2 cases were T4N 1M0, 5 cases were T4N2M0. The 1-year, 3-year, 5-year survival rates were 84.4% （38/45）, 51.7% （15/29）, 53.8% （7/13） respectively. Conclu-sion： The double sleeve Iobectomy of the bronchus and the pulmonary artery can maximumly reserve the normal lung tissues while removing tumors, and avoid pneumonectomy. The surgery was safe and effective, while it required a high technique.展开更多

Sleeve gastrectomy(SG) has emerged over the last few years to be an ideal bariatric procedure because it has several advantages compared to more complex bariatric procedures,including avoiding an intestinal bypass. However,several published follow-up studies report an increased rate of gastroesophageal reflux(GERD) after a SG. GERD is described as either de novo or as being caused by aggravation of preexisting symptoms. However,the literature on this topic is ambivalent despite the potentially increased rate of GERDs that may occur after this common bariatric procedure. This article reviews the mechanisms responsible for GERD in obese subjects as well as the results after a SG with respect to GERD. Future directions for clinical research are discussed along with the current surgical options for morbidly obese patients with GERD and undergoing bariatric surgery.展开更多
文摘BACKGROUND Sleeve fracture of the patella is an unusual fracture,almost unique to children.The majority of sleeve fractures involve the inferior patellar pole.However,sleeve fractures of the superior pole of the patella are extremely rare in adults.CASE SUMMARY An 18-year-old male patient fell while running in the morning.The patient had tenderness to palpation at the superior pole of the patella,with a palpable gap over the upper part of the patella in both knees.We applied two 4.5-mm suture anchors with the Krackow stitch to repair the sleeve fracture,augmented by autogenous gracilis through performing the figure-of-eight technique.The patient regained approximately the full range of motion of the knee joint without any quadriceps weakness and a normal gait 6 weeks after surgery.CONCLUSION Sleeve fractures of the superior pole of the patella are extremely rare in adults,especially bilateral sleeve fractures.Suture anchors,augmented by autogenous gracilis,provided secure fixation and achieved excellent results in this rare injury.
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 significant global health concern, often leading to comorbidities such as cardiovascular diseases, diabetes, and hypertension. Bariatric surgery, including sleeve gastrectomy (SG), is a proven treatment for morbid obesity, offering substantial weight loss and resolution of comorbidities. However, post-surgical complications, particularly anorectal disorders such as hemorrhoids and anal fissures, remain underexplored, especially in Saudi Arabia. This retrospective cohort study aimed to assess the prevalence, risk factors, and impact of anal complications following SG at Almoosa Specialist Hospital in Alhassa, Saudi Arabia. A total of 205 patients who underwent SG between January 2020 and December 2021 were surveyed, with 148 eligible participants included in the final analysis. Results indicated that 8.8% of patients experienced anal complications, with anal fissures (53.8%) and hemorrhoids (38.5%) being the most common. These complications typically occurred 2 - 6 months post-surgery. Lifestyle factors such as physical activity and fluid intake were found to significantly reduce the likelihood of anal issues. Moreover, 69.2% of patients with anal problems reported a negative impact on their quality of life. The study highlights the importance of targeted post-operative care, including lifestyle modifications, to mitigate the impact of anal complications. The findings suggest that ongoing education and comprehensive support for bariatric surgery patients, particularly regarding physical activity and hydration, are critical for improving long-term health outcomes.

文摘BACKGROUND Laparoscopic sleeve gastrectomy(LSG)can lead to complete resolution of hypertension in most patients with obesity within one year.However,the preoperative factors related to this resolution are still unclear.AIM To clarify the impact of relevant factors,particularly perirenal fat,on postoperative hypertension resolution.METHODS In this retrospective single-center study,a total of 138 patients with obesity and hypertension were included,all of whom underwent LSG in the hospital and were followed up for one year.Multivariate logistic regression models were used to identify independent risk factors for postoperative hypertension resolution.Generalized additive models were employed to clarify the nonlinear relationships between these factors and hypertension resolution,and their predictive values were compared using fivefold cross-validation.RESULTS After LSG,107 patients(77.5%)experienced hypertension resolution,while 31 patients(22.5%)did not achieve resolution.Both the preoperative perirenal fat area(PrFA)and perirenal fat thickness were independent risk factors for postoperative hypertension resolution(P<0.001 vs P=0.002).These factors are curvilinearly correlated with the hypertension resolution rate,but PrFA has a better predictive value than perirenal fat thickness dose(area under the curve=0.846 vs 0.809).Compared with those with PrFA≥18 cm2,patients with PrFA<18 cm2 had a higher hypertension resolution rate[87%vs 68.1%;odds ratio(95%confidence interval)=3.513(1.367-9.902),P=0.012].CONCLUSION PrFA is a preoperative predictor of postoperative hypertension resolution.It is curvilinearly associated with the resolution rate,and patients with PrFA<18 cm²have better hypertension resolution outcomes after LSG.

文摘Laparoscopic sleeve gastrectomy(LSG),as an effective treatment for morbid obesity and its metabolic complications,exerts its therapeutic effects by significantly reducing body weight and improving metabolic disorders.Its core mechanisms involve multi-level regulation of free fatty acid(FFA)metabolism and chronic low-grade inflammatory states(represented by tumor necrosis factor-alpha,TNF-α).This paper systematically reviews the direct impact of LSG on FFA dynamics including lipolysis,tissue uptake,and oxidation,as well as the molecular pathways through which it indirectly regulates TNF-αby reducing adipose tissue inflammation,improving intestinal barrier function,and modulating epigenetic modifications such as SCD gene methylation.Postoperatively,FFA and TNF-αform a bidirectional promoting feedback loop.LSG effectively breaks this vicious cycle of mutual promotion between the two under obese conditions by reducing FFA levels and inhibiting TNF-αexpression.Lower FFA levels alleviate inflammatory signal activation,while reduced TNF-αinhibits lipolysis,collectively promoting the restoration of insulin sensitivity.A thorough understanding of these mechanisms provides a theoretical basis for optimizing surgical strategies and developing targeted therapies.
文摘This paper examines the cultural symbolism of the character“袖”(sleeve)through an analysis of its historical evolution,linking the intricate relationship between traditional clothing design and linguistic expression.Drawing on frameworks from cognitive linguistics,particularly metaphor and metonymy,the study investigates the diverse metaphorical uses of“袖”in the Chinese language.Through corpus-based analysis,findings reveal that these metaphorical expressions are shaped by cultural traditions,daily practices,and cognitive mechanisms.While many traditional usages of the term have diminished in modern discourse,it retains a rich spectrum of metaphorical meanings,reflecting the unique interconnection between language and culture in Chinese society.This research provides a nuanced understanding of the interplay between Chinese characters and traditional clothing,offering fresh perspectives for metaphor studies within cognitive linguistics.
文摘Background:Sleeve lobectomy(SL)presents an attractive option compared to pneumonectomy(PN)for patients with central or locally advanced non-small cell lung cancer(NSCLC).This study aimed to assess the advantages of SL over PN for NSCLC via a meta-analysis.Methods:We performed a systematic review and cumulative analysis of comparative studies that reported both postoperative and survival outcomes for SL and PN.This was accomplished through a thorough search of electronic databases,including PubMed,EMBASE,and the Cochrane library,from inception to April 2023.Results:A total of 5727 patients(SL:1945;PN:3782)from thirty-one studies were analyzed.The meta-analysis focused on perioperative mortality,local recurrence,and overall survival.The SL group exhibited a significantly lower rate of perioperative mortality(OR=0.43,95%CI=0.32–0.60,P<0.0001).However,no significant difference was observed in local recurrence rates between SL and PN(OR=1.25;95%CI,0.92 to 1.69;P=0.16).Additionally,the survival rates at 1 year and 5 years in the SL cohort(1-year:0.14,95%CI:0.12 to 0.17,p<0.0001;5-year:2.15,95%CI:1.77 to 2.61,p<0.0001)along with the survival in patients with pN0 or pN1 at 5 years(OR=0.13,95%CI 0.04 to 0.22;P=0.006)were notably superior compared to those undergoing PN.Conclusions:Sleeve lobectomy should be regarded as a viable alternative to pneumonectomy for treating NSCLC.
文摘BACKGROUND Obesity is a significant global health concern,with laparoscopic sleeve gastrectomy(LSG)being the most commonly performed bariatric surgery in the Middle East,including Saudi Arabia,due to its simplicity and effectiveness in achieving weight loss.However,the long-term effects of LSG on gastroesophageal reflux disease(GERD)and Barrett’s esophagus(BE)remain areas of active investigation.AIM To determine the prevalence of GERD and BE 5 years post-LSG in a Saudi Arabian population.METHODS A retrospective cohort study was conducted at a tertiary bariatric referral center in Saudi Arabia.Patients who underwent LSG 5 years prior and completed postoperative gastroscopy were included.Data on demographics,comorbidities,GERD symptoms,and endoscopic findings were extracted.GERD was defined clinically,esophagitis was graded per the Los Angeles classification,and BE was defined histologically.Multivariate logistic regression was used to identify predictors of GERD,endoscopic esophagitis(EE),and BE.RESULTS The study included 114 patients(mean age:44 years;61%female).GERD prevalence increased from 16%preoperatively to 64%5 years post-LSG,with 54%of cases representing de novo GERD.EE prevalence rose to 30%,with 23%of cases being de novo.BE was detected in 2.6%of patients,all presenting with short-segment BE without intestinal metaplasia.On univariate analysis,the pre-LSG body mass index was significantly associated with EE(P=0.038),and age was significantly associated with BE(P=0.037).However,on multivariate analysis,only hypertension was independently associated with GERD development(odds ratio=5.09;P=0.01).No factors were significantly associated with EE or BE on multivariate analysis.CONCLUSION This study highlights the significant increase in GERD and EE prevalence 5 years post-LSG,with a relatively low but notable incidence of BE.The findings underscore the need for long-term endoscopic surveillance,particularly for older patients,even in populations with lower baseline.
文摘BACKGROUND Bariatric surgery is one of the most effective ways to treat morbid obesity,and postoperative nausea and vomiting(PONV)is one of the common complications after bariatric surgery.At present,the mechanism of the high incidence of PONV after weight-loss surgery has not been clearly explained,and this study aims to investigate the effect of surgical position on PONV in patients undergoing bariatric surgery.AIM To explore the effect of the operative position during bariatric surgery on PONV.METHODS Data from obese patients,who underwent laparoscopic sleeve gastrectomy(LSG)in the authors’hospital between June 2020 and February 2022 were divided into 2 groups and retrospectively analyzed.Multivariable logistic regression analysis and the t-test were used to study the influence of operative position on PONV.RESULTS There were 15 cases of PONV in the supine split-leg group(incidence rate,50%)and 11 in the supine group(incidence rate,36.7%)(P=0.297).The mean operative duration in the supine split-leg group was 168.23±46.24 minutes and 140.60±32.256 minutes in the supine group(P<0.05).Multivariate analysis revealed that operative position was not an independent risk factor for PONV(odds ratio=1.192,95%confidence interval:0.376-3.778,P=0.766).CONCLUSION Operative position during LSG may affect PONV;however,the difference in the incidence of PONV was not statistically significant.Operative position should be carefully considered for obese patients before surgery.
文摘BACKGROUND Differences in the preoperative characteristics and weight loss outcomes after sleeve gastrectomy(SG)between patients with familial aggregation of obesity(FAO)and patients with sporadic obesity(SO)have not been elucidated.AIM To explore the impact of SG on weight loss and the alleviation of obesity-related comorbidities in individuals with FAO.METHODS A total of 193 patients with obesity who underwent SG were selected.Patients with FAO/SO were matched 1:1 by propensity score matching and were categorized into 4 groups based on the number of first-degree relatives with obesity(1 SO vs 1FAO,2SO vs 2FAO).The baseline characteristics,weight loss outcomes,prevalence of obesity-related comorbidities and incidence of major surgeryrelated complications were compared between groups.RESULTS We defined FAO as the presence of two or more first-degree relatives with obesity.Patients with FAO did not initially show significant differences in baseline data,short-term postoperative weight loss,or obesity-related comorbidities when compared to patients with SO preoperatively.However,distinctions between the two groups became evident at the two-year mark,with statistically significant differences in both percentage of total weight loss(P=0.006)and percentage of excess weight loss(P<0.001).The FAO group exhibited weaker remission of type 2 diabetes mellitus(T2DM)(P=0.031),hyperlipidemia(P=0.012),and non-alcoholic fatty liver disease(NAFLD)(P=0.003)as well as a lower incidence of acid reflux(P=0.038).CONCLUSION FAO patients is associated with decreased mid-to-long-term weight loss outcomes;the alleviation of T2DM,hyperlipidemia and NAFLD;and decreased incidence of acid reflux postoperatively.

文摘Grouting defects are an inherent challenge in construction practices,exerting a considerable impact on the operational structural integrity of connections.This investigation employed the impact-echo technique for the detection of grouting anomalies within connections,enhancing its precision through the integration of wavelet packet energy principles for damage identification purposes.A series of grouting completeness assessments were meticulously conducted,taking into account variables such as the divergent material properties of the sleeves and the configuration of adjacent reinforcement.The findings revealed that:(i)the energy distribution for the highstrength concrete cohort predominantly occupied the frequency bands 42,44,45,and 47,whereas for other groups,it was concentrated within the 37 to 40 frequency band;(ii)the delineation of empty sleeves was effectively discernible by examining the wavelet packet energy ratios across the spectrum of frequencies,albeit distinguishing between sleeves with 50%and full grouting density proved challenging;and(iii)the wavelet packet energy analysis yielded variable detection outcomes contingent on the material attributes of the sleeves,demonstrating heightened sensitivity when applied to ultrahigh-performance concrete matrices and GFRP-reinforced steel bars.
文摘Objective: This case report aimed to demonstrate a possible neuromuscular effect of Latarjet nerves transection or truncal vagotomy, in association with sleeve gastrectomy plus antrojejunostomy, in order to reproduce a Roux-en-Y gastric bypass (RYGB) mechanistic principles, in patients with previous Sleeve Gastrectomy (SG) who had had weight regain, with or without concomitant gastroesophageal reflux disease (GERD). Background: Sleeve gastrectomy (SG) is one of the most frequently performed bariatric operations worldwide. Nevertheless, weight regain and gastroesophageal reflux disease (GERD) have been consistently demonstrated, in association with this technique, which may require a revisional procedure. RYGB is an option in such a situation but, implies in gastrointestinal exclusions, which represents a shortcoming of this revision. Surpassing this inconvenient would be of great value for the patients. Methods: We describe herein two cases of SG revision for weight regain and GERD, with a follow-up of one year. Gastroesophageal reflux disease was evaluated by validated questionnaire, upper endoscopy, seriography, high resolution manometry (HRM) and impedance pHmetry (I-pHmetry), in the pre and postoperative periods. A re-Sleeve Gastrectomy with antrojejunal anastomosis was done in both cases, after informed consents. The Latarjet nerves were transected in one case, due to a bleeding in the left gastric vessels and a truncal vagotomy was required in the other, to appropriately treat an associated hiatal hernia. Results: In the postoperative evaluation it was observed a pyloric spasm in both cases, during seriography and endoscopy, kept until the one-year follow-up. There was unidirectional contrast flow to the gastrointestinal anastomosis, filling the jejunal limb, in radiologic contrast study. No contrast passed through the pylorus. Nonetheless, the duodenum was kept endoscopically accessible. In the one-year evaluation, weight loss was adequate and GERD resolution was obtained in both cases, confirmed by endoscopic and functional esophageal assessment, together with symptoms questionnaire. Conclusion: The association of Latarjet nerves sectioning or truncal vagotomy with re-sleeve gastrectomy plus gastrointestinal anastomosis (antrojejunal), in a revision for a failed sleeve, can represent a technical approach, to reproduce RYGB results, without exclusions and with duodenum endoscopic accessibility maintenance. It maybe could be applied for primary surgeries. Additional studies are necessary to confirm this hypothesis.

文摘During peripheral nerve transposition repair, if the diameter difference between transposed nerves is large or multiple distal nerves must be repaired at the same time, traditional epineurial neurorrhaphy has the problem of high tension at the suture site, which may even lead to the failure of nerve suture. We investigated whether a small gap bio-sleeve suture with different inner diameters at both ends can be used to repair a 2-mm tibial nerve defect by proximal transposition of the common peroneal nerve in rats and compared the results with the repair seen after epineurial neurorrhaphy. Three months after surgery, neurological function, nerve regeneration, and recovery of nerve innervation muscle were assessed using the tibial nerve function index, neuroelectrophysiological testing, muscle biomechanics and wet weight measurement, osmic acid staining, and hematoxylin-eosin staining. There was no obvious inflammatory reaction and neuroma formation in the tibial nerve after repair by the small gap bio-sleeve suture with different inner diameters at both ends. The conduction velocity, muscle strength, wet muscle weight, cross-sectional area of muscle fibers, and the number of new myelinated nerve fibers in the biosleeve suture group were similar to those in the epineurial neurorrhaphy group. Our findings indicate that small gap bio-sleeve suture with different inner diameters at both ends can achieve surgical suture between nerves of different diameters and promote regeneration and functional recovery of injured peripheral nerves.

文摘Objective： The aim of our study was to introduce the surgical method and evaluate the efficacy of double sleeve Iobectomy of the bronchus and the pulmonary artery in treatment for the central lung cancer. Method： From March 1995 to October 2010, double sleeve Iobectomy of the bronchus and the pulmonary artery was performed in 45 cases with central lung cancer that involved the bronchial opening of an upper lobe of the lungs or the main bronchus and＇pulmonary artery but didn＇t involve any lower lobes. Among them, left upper Iobectomy was performed in 37 cases, right medium-upper Iobectomy was performed in 6 cases and right upper Iobectomy was performed in 2 cases. Results： Postoperative complications were found in 12 cases. Among them, 3 cases were arrhythmia, 1 case was acute heart failure, 6 cases were obstructive pneumo-nia and pulmonary atelectasis, 2 cases were bronchial anastomotic fistula. Two cases died of cerebral infarction and massive hemoptysis respectively. Thirty-one cases were squamous carcinoma, 7 cases were adenocarcinoma, 4 cases were small cell lung cancer, 1 case was adenosquamous carcinoma, 1 case was sarcomatoid carcinomas, 1 case was mucinous adeno- carcinoma. Ten cases were T3NOM0, 11 cases were T3N 1M0, 17 cases were T3N2M0, 2 cases were T4N 1M0, 5 cases were T4N2M0. The 1-year, 3-year, 5-year survival rates were 84.4% （38/45）, 51.7% （15/29）, 53.8% （7/13） respectively. Conclu-sion： The double sleeve Iobectomy of the bronchus and the pulmonary artery can maximumly reserve the normal lung tissues while removing tumors, and avoid pneumonectomy. The surgery was safe and effective, while it required a high technique.
文摘Bariatric surgery is the only effective procedure that provides long-term sustained weight loss. Sleeve gastrectomy(SG) has emerged over the last few years to be an ideal bariatric procedure because it has several advantages compared to more complex bariatric procedures,including avoiding an intestinal bypass. However,several published follow-up studies report an increased rate of gastroesophageal reflux(GERD) after a SG. GERD is described as either de novo or as being caused by aggravation of preexisting symptoms. However,the literature on this topic is ambivalent despite the potentially increased rate of GERDs that may occur after this common bariatric procedure. This article reviews the mechanisms responsible for GERD in obese subjects as well as the results after a SG with respect to GERD. Future directions for clinical research are discussed along with the current surgical options for morbidly obese patients with GERD and undergoing bariatric surgery.
