It’s practice in the capital of Cameroon is still a luxury and it is almost non-existent in peripheral zones. The aim of this study is to present the results of the first laparoscopy surgeries done at the Yokadouma district hospital located in the east region at 600 km from Yaoundé. Methods: This is a descriptive prospective study carried out from march 2020 to march 2021 in the general surgery department of the Yokadouma district hospital. Patients operated by laparoscopy during this period were included in the study giving a sample size of 40 patients. The data collected were analyzed by “Census software and Survey Processing System” (CSPRO). Results: Majority of patients, 57.5% were males and aged between 16 and 30 years (32.5% of cases). Most patients (30% of patients) were farmers. Transabdominal preperitoneal prosthesis plasty for hernia represented 55% of interventions followed by appendicectomy (15%) and cholecystectomy (7.5%). Two procedures (0.8%) required conversion into open surgery. Post-operative complications were very rare and were encountered just by one patient who presented a parietal suppuration. Interventions in 77% of cases cost less than 200,000 CFA FRANCS (400$). Conclusion: The example of Yokadouma shows that laparoscopy should be developed in peripheral zones so that its residents can benefit from its multiple advantages.展开更多

Traditionally, bariatric surgeries have been categorized into hypoabsorptive, restrictive, or hybrid approaches. However, these classifications inadequately reflect the complex anatomical and physiological alterations associated with modern surgical methodologies. This paper explores the evolution of metabolic surgeries, emphasizing the integration of physiological concepts into classic procedures to provide more tailored and effective treatment options for obesity and its comorbidities. Finally, the proposal for a new classification based on current metabolic concepts will facilitate communication among patients, doctors, and healthcare professionals.

The experience gained through VATS techniques, enhancement of the surgical instruments ,improvement of high definition cameras and avoidance of intubated general anesthesia have been the greatest advances to minimize the trauma to the patient. Uniportal VATS for major resections has become a revolution in the treatment of lung pathologies since initially described 4 years ago. The huge number of surgical videos posted on specialized websites, live surgery events and experimental courses has contributed to the rapid learning of uniportal major thoracoscopic surgery during the last years. The future of the thoracic surgery is based on evolution of surgical procedures and anesthetic techniques to try to reduce the trauma to the patient. Further development of new technologies probably will focus on sealing devices for all vessels and fissure, refined staplers and instruments, improvements in 3D systems or wireless cameras, and robotic surgery. As thoracoscopic techniques continue to evolve exponentially, we can see the emergence of new approaches in the anesthetical and the perioperative management of these patients. Advances in anesthesia include lobectomies performed without the employment of general anesthesia, through maintaining spontaneous ventilation, and with minimally sedated patients. Uniportal VATS resections under spontaneous ventilation probably represent the least invasive approach to operate lung cancer.展开更多

RESULTS A total of 266 patients underwent curative surgery during the study period. The median age of the study cohort was 68 year(range 26 to 91) with a followup of 7.9 years(range 4.6 to 12.6). Resection was undertaken electively in 225(84.6%) patients and emergency resection in 35(13.2%). Data on timing of surgery was missing in 6 patients. Recurrence was noted in 67(25.2%) during the study period and was predominantly early within 3 years(82.1%) and involved hepatic metastasis in 73.1%. Emergency resection(OR = 3.60, P = 0.001), T4 stage(OR = 4.33, P < 0.001) and lymphovascular invasion(LVI) (OR = 2.37, P = 0.032) were associated with higher risk of recurrent disease. Emergency resection, T4 disease and a high lymph node ratio(LNR) were strong independent predictors of adverse long-term survival. CONCLUSION Emergency surgery is associated with adverse disease free and long-term survival. T4 disease, LVI and LNR provide strong independent predictive value of longterm outcome and can inform surveillance strategies to improve outcomes.展开更多

Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers,for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a laparoscopic approach to the treatment of the most common emergency surgical conditions.展开更多

Microsurgery could be a very valuable technique to improve experimental models of liver diseases. Microdissection and microsutures are the two main microsurgical techniques that can be considered for classifying the experimental models developed for liver research in the rat. Partial portal vein ligation, extrahepatic cholestasis and hepatectomies are all models based on microdissection. On the other hand, in portacaval shunts, orthotopic liver transplantation and partial heterotopic liver transplantation, the microsuture techniques stand out. By reducing surgical complications, these microsurgical techniques allow for improving the resulting experimental models. If good experimental models for liver research are successfully developed, the results obtained from their study might be particularly useful in patients with liver disease. Therefore experimental liver microsurgery could be an invaluable way to translate laboratory data on liver research into new clinical diagnostic and therapeutic strategies.展开更多

Among its complications, leaks are the most serious and life threatening. The placement of esophageal, covered, self-expandable metal stents in these cases has been performed by many authors but reports on the outcome of this procedure are limited and the technical aspects are not well defined. Stent migration is the main complication of the procedure and poses a challenge to the surgeon, with a limited number of options. Here we evaluate the technical and clinical outcome of a new, dedicated, self-expanding metal stent, comparing the advantages of this stent to those traditionally used to treat staple-line leak after sleeve gastrectomy. While published data are limited, they seem support the use of this kind of new stent as the best option for the stenting treatment of a staple-line leak after sleeve gastrectomy, over other kinds of stents. Further studies based on larger series are needed to better evaluate patient outcome.展开更多

It is estimated that about 20% of the general population is affected by PCNs. Some of those lesions can progress till cancer, while others behave in a benign fashion. In particular intraductal papillary mucinousneoplasms of the pancreas can be considered as the pancreatic analogon to colonic polyps. Treatment of these precursor lesions at an early stage can potentially reduce pancreas cancer mortality and introduce a new "era" of preemptive pancreatic surgery. However, only few of those lesions have an aggressive behavior. The accuracy of preoperative diagnosis, i.e., the distinction between the various PCNs is around 60%, and the ability to predict the future outcome is also less accurate. For this reason, a significant number of patients are currently over-treated with an unnecessary, high-risk surgery. Furthermore, the majority of patients with PCN are on life-long follow-up with imaging modality, which has huge cost implications for the Health Care System for limited benefits considering that a significant proportion of PCNs are or behave like benign lesions. The current guidelines for the diagnosis and management of PCNs are more based on expert opinion than on evidence. For all those reasons, the management of cystic tumors of the pancreas remains a controversial area of pancreatology. On one hand, the detection of PCNs and the surgical treatment of pre-cancerous neoplasms can be considered a big opportunity to reduce pancreatic cancer related mortality. On the other hand, PCNs are associated with a considerable risk of under- or over- treatment of patients and incur high costs for the Health Care System.展开更多

This study aimed to identify the predictive factors for gallstone formation after bariatric surgery. Patient and methods: The files of all morbidly obese patients underwent bariatric surgery in our unit during the period from March 2003 till October 2010 were reviewed and analyzed. All patients underwent routine preoperative ultrasonography and selective concomitant cholecystectomy was done in all patients with ultrasonographic-confirmed cholelithiasis. After excluding cases with prior and concomitant cholecystectomies, patients were divided into two groups;those who developed gallstones and those who did not and the two groups were compared. Results: Of the 143 reviewed files 135 were eligible to be included in the study. The incidence of cholelithiasis before surgery was 25.9% (35 cases). 19 cases (19%) of the 100 cases free at surgery developed gallstone at a mean of 13.2 months. Comparing the two groups, no significant difference was revealed regarding gender, age, preoperative BMI or type of the operation. But the percent of excess weight loss was significantly higher in the group that formed gallstones. Conclusion: Gender, age, preoperative BMI and type of the operation were not predictive of gallstones formation after bariatric surgery. The percent of excess weight loss was the only predictive postoperative factor.展开更多

文摘BACKGROUND Gastrectomy is recognized as a potential cause of exocrine pancreatic insufficiency(EPI).However,limited data are available regarding the incidence and impact of EPI on quality of life(QoL)following gastric surgery.AIM To evaluate incidence and severity of EPI after gastrectomy and its effect on QoL at least one year after surgery.METHODS EPI was assessed using fecal elastase measurement and classified into:(1)No-EPI(fecal elastase>200μg/g);(2)Moderate EPI(fecal elastase 100–200μg/g);and(3)severe EPI(fecal elastase<100μg/g).QoL was measured using the Gastrointestinal Quality of Life Index(GIQLI)questionnaire.RESULTS Sixteen out of 44(36.4%)patients developed EPI post-operatively:9(56.2%)patients had moderate EPI while 7(43.8%)patients had severe EPI.Severe EPI was more frequently observed in younger patients(5/7:71.4%;P=0.05),in more advanced disease stages(7/7:100%;P=0.05),lymph nodes metastases(7/7:100%;P=0.04)and in the mixed histotypes(4/7:66.7%;P=0.02)compared to the no-EPI and moderate EPI groups.QoL analysis showed that severe EPI was associated with a significantly lower overall GIQLI score[65(59–92)]compared to the no-EPI/moderate EPI groups[89(84–100)](P=0.002).Lower scores were particularly evident in the core(P<0.0001)and disease-specific symptoms domains(P=0.002)in the severe EPI group compared to the no-EPI/moderate EPI groups.CONCLUSION Gastrectomy is a cause of EPI.Younger patients,aggressive disease and advanced stages are significant risk factors for more severe EPI.Severe EPI worsens QoL,being associated with a higher rate of gastrointestinal symptoms.

文摘Bariatric and metabolic surgeries have gained extensive popularity and trust due to their documented efficacy and safety in managing not only obesity but also associated comorbidities such as diabetes mellitus, hypertension, dyslipidemia, sleep apnea, and joint pain. Traditionally, bariatric surgeries have been categorized into hypoabsorptive, restrictive, or hybrid approaches. However, these classifications inadequately reflect the complex anatomical and physiological alterations associated with modern surgical methodologies. This paper explores the evolution of metabolic surgeries, emphasizing the integration of physiological concepts into classic procedures to provide more tailored and effective treatment options for obesity and its comorbidities. Finally, the proposal for a new classification based on current metabolic concepts will facilitate communication among patients, doctors, and healthcare professionals. Additionally, it will enable a more didactic and standardized approach to data collection for conducting studies and publications.

文摘AIM:To study the results of stem-cell therapy under a Compassionate-use Program for patients with recurrent anal fistulae.METHODS:Under controlled circumstances,and approved by European and Spanish laws,a Compassionate-use Program allows the use of stem-cell therapy for patients with very complex anal fistulae.Candidates had previously undergone multiple surgical interventions that had failed to resolve the fistulae,and presented symptomatic recurrence.The intervention consisted of limited surgery(with closure of the internal opening),followed by local implant of stem cells in the fistula-tract wall.Autologous expanded adipose-derived stem cells were the main cell type selected for implant.The first evaluation was performed on the 8th postoperative week;outcome was classified as response or partial response.Evaluation one year after the intervention confirmed if complete healing of the fistula was achieved.RESULTS:Ten patients(8 male)with highly recurrent and complex fistulae were treated(mean age:49years,range:28-76 years).Seven cases were nonCrohn’s fistulae,and three were Crohn’s-associated fistulae.Previous surgical attempts ranged from 3to 12.Two patients presented with preoperative incontinence(Wexner scores of 12 and 13 points).After the intervention,six patients showed clinical response on the 8th postoperative week,with a complete cessation of suppuration from the fistula.Three patients presented a partial response,with an evident decrease in suppuration.A year later,six patients(60%)remained healed,with complete reepithelization of the external opening.Postoperative Wexner Scores were 0 in six cases.The two patients with previous incontinence improved their scores from12 to 8 points and from 13 to 5 points.No adverse reactions or complications related to stem-cell therapy were reported during the study period.CONCLUSION:Stem cells are safe and useful for treating anal fistulae.Healing can be achieved in severe cases,sparing fecal incontinence risk,and improving previous scoring.
文摘Thoracic Surgery is a continuous evolving specialty. In the past, thoracic surgeons had to make large incisions in order to operate any pathology inside the chest. This often meant big, painful and ugly scars and long recovery times after surgery. But he history of thoracic surgery changed since the begining of video-assisted thoracoscoDic surgery （VATg3
文摘AIM To evaluate prognostic pathological factors associated with early metachronous disease and adverse longterm survival in these patients.METHODS Clinical and histological features were analysed retrospectively over an eight-year period for prognostic impact on recurrent disease and overall survival in patients undergoing curative resection of a primary colorectal cancer. RESULTS A total of 266 patients underwent curative surgery during the study period. The median age of the study cohort was 68 year(range 26 to 91) with a followup of 7.9 years(range 4.6 to 12.6). Resection was undertaken electively in 225(84.6%) patients and emergency resection in 35(13.2%). Data on timing of surgery was missing in 6 patients. Recurrence was noted in 67(25.2%) during the study period and was predominantly early within 3 years(82.1%) and involved hepatic metastasis in 73.1%. Emergency resection(OR = 3.60, P = 0.001), T4 stage(OR = 4.33, P < 0.001) and lymphovascular invasion(LVI) (OR = 2.37, P = 0.032) were associated with higher risk of recurrent disease. Emergency resection, T4 disease and a high lymph node ratio(LNR) were strong independent predictors of adverse long-term survival. CONCLUSION Emergency surgery is associated with adverse disease free and long-term survival. T4 disease, LVI and LNR provide strong independent predictive value of longterm outcome and can inform surveillance strategies to improve outcomes.
文摘The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers,for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a laparoscopic approach to the treatment of the most common emergency surgical conditions.

文摘The development of microsurgery has been dependent on experimental animals. Microsurgery could be a very valuable technique to improve experimental models of liver diseases. Microdissection and microsutures are the two main microsurgical techniques that can be considered for classifying the experimental models developed for liver research in the rat. Partial portal vein ligation, extrahepatic cholestasis and hepatectomies are all models based on microdissection. On the other hand, in portacaval shunts, orthotopic liver transplantation and partial heterotopic liver transplantation, the microsuture techniques stand out. By reducing surgical complications, these microsurgical techniques allow for improving the resulting experimental models. If good experimental models for liver research are successfully developed, the results obtained from their study might be particularly useful in patients with liver disease. Therefore experimental liver microsurgery could be an invaluable way to translate laboratory data on liver research into new clinical diagnostic and therapeutic strategies.

文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical,clinical,and oncological outcomes.METHODS This is a propensity score-matched case-control study,comparing three treatment arms:robotic gastrectomy(RG),laparoscopic gastrectomy(LG),open gastrectomy(OG).Data collection started after sharing a specific study protocol.Data were recorded through a tailored and protected web-based system.Primary outcomes:harvested lymph nodes,estimated blood loss,hospital stay,complications rate.Among the secondary outcomes,there are:operative time,R0 resections,POD of mobilization,POD of starting liquid diet and soft solid diet.The analysis includes the evaluation of type and grade of postoperative complications.Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies.To guarantee homogenous distribution of cases,patients in the RG,LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper=0.2.The successful matching resulted in a total sample of 604 patients(RG=151;LG=151;OG=302).The three groups showed no differences in all baseline patients characteristics,type of surgery(P=0.42)and stage of the disease(P=0.16).Intraoperative blood loss was significantly lower in the LG(95.93±119.22)and RG(117.91±68.11)groups compared to the OG(127.26±79.50,P=0.002).The mean number of retrieved lymph nodes was similar between the RG(27.78±11.45),LG(24.58±13.56)and OG(25.82±12.07)approach.A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P<0.0001).A similar complications rate was found(P=0.13).The leakage rate was not different(P=0.78)between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery.The main highlighted benefit is a faster postoperative functional recovery.
文摘We read with great interest the article that retrospectively analyzed 814 patients with primary gastric cancer,who underwent minimally invasive R0 gastrectomy between 2009 and 2014 by grouping them in laparoscopic vs robotic procedures.The results of the study highlighted that age,American Society of Anesthesiologists status,gastrectomy type and pathological T and N status were the main prognostic factors of minimally invasive gastrectomy and showed how the robotic approach may improve long-term outcomes of advanced gastric cancer.According to most of the current literature,robotic surgery is associated with a statistically longer operating time when compared to open and laparoscopic surgery;however,looking at the adequacy of resection,defined by negative surgical margins and number of lymph nodes removed,it seems that robotic surgery gives better results in terms of the 5-year overall survival and recurrencefree survival.The robotic approach to gastric cancer surgery aims to overcome the difficulties and technical limitations of laparoscopy in major surgery.The threedimensional vision,articulation of the instruments and good ergonomics for the surgeon allow for accurate and precise movements which facilitate the complex steps of surgery such as lymph node dissection,esophagus-jejunal anastomosis packaging and reproducing the technical accuracy of open surgery.If the literature,as well as the analyzed study,offers us countless data regarding the short-term oncological results of robotic surgery in the treatment of gastric cancer,satisfactory data on long-term follow-up are lacking,so future studies are necessary.
文摘One hundred years ago, the first patients with lung cancer have been reported （1）. Since then long term survival in patients with lung cancer remains disappointing, and this is not only due to the delayed diagnosis but also to the dismal survival of the 70%-75% inoperable patients.

文摘Obesity is increasing worldwide,and this has major implications in the setting of kidney transplantation.Patients with obesity may have limited access to transplantation and increased posttransplant morbidity and mortality.Most transplant centers incorporate interventions aiming to target obesity in kidney transplant candidates,including dietary education and lifestyle modifications.For those failing nutritional restriction and medical therapy,the use of bariatric surgery may increase the transplant candidacy of patients with obesity and endstage renal disease(ESRD)and may potentially improve the immediate and late outcomes.Bariatric surgery in ESRD patients is associated with weight loss ranging from 29.8% to 72.8% excess weight loss,with reported mortality and morbidity rates of 2% and 7%,respectively.The most commonly performed bariatric surgical procedures in patients with ESRD and in transplant patients are laparoscopic sleeve gastrectomy(LSG)and laparoscopic Roux-en-Y gastric bypass.However,the correct timing of bariatric surgery and the ideal type of surgery have yet to be determined,although pretransplant LSG seems to be associated with an acceptable risk-benefit profile.We review the impact of obesity on kidney transplant candidates and recipients and in potential living kidney donors,exploring the potential impact of bariatric surgery in addressing obesity in these populations,thereby potentially improving posttransplant outcomes.
文摘Laparoscopic sleeve gastrectomy is a surgical procedure that is being increasingly performed on obese patients. Among its complications, leaks are the most serious and life threatening. The placement of esophageal, covered, self-expandable metal stents in these cases has been performed by many authors but reports on the outcome of this procedure are limited and the technical aspects are not well defined. Stent migration is the main complication of the procedure and poses a challenge to the surgeon, with a limited number of options. Here we evaluate the technical and clinical outcome of a new, dedicated, self-expanding metal stent, comparing the advantages of this stent to those traditionally used to treat staple-line leak after sleeve gastrectomy. While published data are limited, they seem support the use of this kind of new stent as the best option for the stenting treatment of a staple-line leak after sleeve gastrectomy, over other kinds of stents. Further studies based on larger series are needed to better evaluate patient outcome.
文摘Pancreatic cystic neoplasms(PCNs) are a high prevalence disease. It is estimated that about 20% of the general population is affected by PCNs. Some of those lesions can progress till cancer, while others behave in a benign fashion. In particular intraductal papillary mucinousneoplasms of the pancreas can be considered as the pancreatic analogon to colonic polyps. Treatment of these precursor lesions at an early stage can potentially reduce pancreas cancer mortality and introduce a new "era" of preemptive pancreatic surgery. However, only few of those lesions have an aggressive behavior. The accuracy of preoperative diagnosis, i.e., the distinction between the various PCNs is around 60%, and the ability to predict the future outcome is also less accurate. For this reason, a significant number of patients are currently over-treated with an unnecessary, high-risk surgery. Furthermore, the majority of patients with PCN are on life-long follow-up with imaging modality, which has huge cost implications for the Health Care System for limited benefits considering that a significant proportion of PCNs are or behave like benign lesions. The current guidelines for the diagnosis and management of PCNs are more based on expert opinion than on evidence. For all those reasons, the management of cystic tumors of the pancreas remains a controversial area of pancreatology. On one hand, the detection of PCNs and the surgical treatment of pre-cancerous neoplasms can be considered a big opportunity to reduce pancreatic cancer related mortality. On the other hand, PCNs are associated with a considerable risk of under- or over- treatment of patients and incur high costs for the Health Care System.
文摘The pursuit of this paper is to collect principal reviews and systematic reviews about hyperthermic intraperitoneal chemotherapy(HIPEC) and cytoreductive surgery(CRS) used in colorectal cancer(CRC).We focus on principal biological aspects of CRC,hyperthermia effects,and surgical procedures.We searched PubMed/MEDLINE for the principal reviews and systematic reviews published from 2010 to 2021 regarding the bimodal treatment(CRS + HIPEC) against local and advanced CRC.In the literature,from several studies,it seems that the efficacy of bimodal treatment with an accurate CRS can extend overall survival.Despite these studies,there are not still any straight guidelines more detailed and scheduled about the use of combined treatment in patients with CRC.Even if the concept is still not very clear and shared,after a careful evaluation of the published data,and after some technical and pathophysiological descriptions,we concluded that it is possible to improve the overall survival and quality of life and to reduce the tumor relapse in patients affected by locally advanced(pT4) CRC with peritoneal metastases.
文摘Background: Obesity alone and rapid weight loss induced by bariatric surgery are recognized risk factors for the development of cholelithiasis. This study aimed to identify the predictive factors for gallstone formation after bariatric surgery. Patient and methods: The files of all morbidly obese patients underwent bariatric surgery in our unit during the period from March 2003 till October 2010 were reviewed and analyzed. All patients underwent routine preoperative ultrasonography and selective concomitant cholecystectomy was done in all patients with ultrasonographic-confirmed cholelithiasis. After excluding cases with prior and concomitant cholecystectomies, patients were divided into two groups;those who developed gallstones and those who did not and the two groups were compared. Results: Of the 143 reviewed files 135 were eligible to be included in the study. The incidence of cholelithiasis before surgery was 25.9% (35 cases). 19 cases (19%) of the 100 cases free at surgery developed gallstone at a mean of 13.2 months. Comparing the two groups, no significant difference was revealed regarding gender, age, preoperative BMI or type of the operation. But the percent of excess weight loss was significantly higher in the group that formed gallstones. Conclusion: Gender, age, preoperative BMI and type of the operation were not predictive of gallstones formation after bariatric surgery. The percent of excess weight loss was the only predictive postoperative factor.
文摘Technological improvements are crucial in the evolution of surgery.Real-time fluorescence-guided surgery(FGS)has spread worldwide,mainly because of its usefulness during the intraoperative decision-making processes.The success of any gastrointestinal oncologic resection is based on the anatomical identification of the primary tumor and its regional lymph nodes.FGS allows also to evaluate the blood perfusion at the gastrointestinal stumps after colorectal or esophageal resections.Therefore,a reduction on the anastomotic leak rates has been postulated as one of the foreseeable benefits provided by the use of FGS in these procedures.Although the use of fluorescence in lymph node detection was initially described in breast cancer surgery,the technique is currently applied in gastric or splenic flexure cancers,as they both present complex and variable lymphatic drainages.FGS allows also to perform intraoperative lymphograms or sentinel lymph node biopsies.New applications of FGS are being developed to assist in the detection of peritoneal metastases or in the evaluation of the tumor resection margins.The present review aims to provide a general overview of the current status of real-time FGS in gastrointestinal oncologic surgery.We put a special focus on the different applications of FGS,discussing the main findings and limitations found in the contemporary literature and also the promising near future applications.
文摘Patients affected by pancreatic ductal adenocarcinoma(PDAC)frequently present with advanced disease at the time of diagnosis,limiting an upfront surgical approach.Neoadjuvant treatment(NAT)has become the standard of care to downstage non-metastatic locally advanced PDAC.However,this treatment increases the risk of a nutritional status decline,which in turn,may impact therapeutic tolerance,postoperative outcomes,or even prevent the possibility of surgery.Literature on prehabilitation programs on surgical PDAC patients show a reduction of postoperative complications,length of hospital stay,and readmission rate,while data on prehabilitation in NAT patients are scarce and randomized controlled trials are still missing.Particularly,appropriate nutritional management represents an important therapeutic strategy to promote tissue healing and to enhance patient recovery after surgical trauma.In this regard,NAT may represent a new interesting window of opportunity to implement a nutritional prehabilitation program,aiming to increase the PDAC patient’s capacity to complete the planned therapy and potentially improve clinical and survival outcomes.Given these perspectives,this review attempts to provide an in-depth view of the nutritional derangements during NAT and nutritional prehabilitation program as well as their impact on PDAC patient outcomes.
