Project description:This study is intended to investigate whether roux-en-y bypass surgery is superior to conventional loop gastrojejunostomy for Malignant gastric outlet obstruction in terms of tolerance to solid food intake. We hypothesize that roux-en-y bypass will be associated with improved solid food intake in the first 30 days after surgery.

Project description:BackgroundThe laparoscopic Roux en-Y gastric bypass (LRYGB) is performed worldwide and is considered by many the gold standard treatment for morbid obesity. However, the difficult access to the gastric remnant and duodenum represents intrinsic limitations. The functional laparoscopic gastric bypass with fundectomy and gastric remnant exploration (LRYGBfse) is a new technique described in attempt to overcome the limitations of the LRYGB. The purpose of this video was to demonstrate the LRYGBfse in a 48-year-old man with type II diabetes and hypertension.MethodsAn intraoperative video has been anonymized and edited to demonstrate the feasibility of LRYGBfse.ResultsThe operation started with the opening of the gastrocolic ligament. Staying close to the gastric wall, the stomach is prepared up to the angle of His. After the placement of a 36-Fr orogastric probe, gastric fundectomy is completed in order to create a 30cc gastric pouch. A polytetrafluoroethylene banding (ePTFE) is placed at the gastro-gastric communication, 7cm below the cardia, and gently closed after bougie retraction. The bypass is completed by the creation of an antecolic Roux-en-Y 150cm alimentary and 150cm biliopancreatic limb.ConclusionThe LRYGBfse is a feasible and safe technique. The possibility to endoscopically explore the excluded stomach with an easy access to the Vater's papilla is a major advantage. Further studies are warranted to deeply explore and compare outcomes with the standard LRYGB.

Project description:Performing endoscopic retrograde cholangiopancreatography in bariatric patients who underwent Roux-en-Y gastric bypass surgery is challenging due to the long anatomical route required to reach the biliopancreatic limb.Assessment of the feasibility and performance of laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography.A retrospective multicenter observational consecutive-patient cohort study of all patients in the period May 2008 to September 2014 with a history of Roux-en-Y gastric bypass who presented with complicated biliary disease and who underwent a laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography. The laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography procedure was similar in all centers and was performed through a 15 mm or 18 mm trocar that was inserted in the gastric remnant. Cholecystectomy was performed concomitantly when indicated.In total, 23 patients underwent a laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography procedure. Two patients required a mini-laparotomy for transgastric access because of a complex surgical history resulting in multiple adhesions. Indications included ascending cholangitis, choledocholithiasis, and biliary pancreatitis. Of the 23 patients, 13 underwent concomitant cholecystectomy. All patients successfully underwent biliary cannulation and sphincterotomy. No endoscopic procedure-related complications (i. e. bleeding, pancreatitis or retroperitoneal perforation) occurred. Mean hospital stay was 2.8 days (range 2 - 4).Transgastric endoscopic retrograde cholangiopancreatography is a feasible approach in the treatment of pancreaticobiliary disease in Roux-en-Y gastric bypass patients, without major complications in our series and allows endoscopic treatment and cholecystectomy to be performed consecutively in a single procedure. In Roux-en-Y gastric bypass patients without a history of prior cholecystectomy presenting with complicated gallstone disease, combining cholecystectomy and transgastric endoscopic retrograde cholangiopancreatography as a first-line approach may be a valid treatment strategy.

Project description:BackgroundPrevious studies reported a similar rate of complications, including stent migration and obstruction, between individualized stents and the standard uncovered stents in gastric outlet obstruction (GOO) caused by distal stomach cancer. The objective of this study was to evaluate the efficacy and safety of funnel stents for management of GOO caused by distal stomach cancer.MethodsThis study was designed as a multicenter, controlled, prospective, and randomized clinical trial involving 4 hospitals. The individualized stent group (44 cases) received cup and funnel covered stents, and the funnel group (44 cases) received only funnel covered stents for management of GOO caused by distal gastric cancer.ResultsAll patients with GOO were treated with cup and funnel stents according to their assigned groups. The rate of GOO resolution was 100% in the funnel group and 97.7% in the individualized stent group. Stent obstruction caused by tumor ingrowth was observed in 1 patient in the individualized stent group, and proximal partial stent migration was observed in 1 patient in each group. Stent obstruction caused by tumor ingrowth was observed in 1 patient in the individualized stent group. There was no statistical difference in stent migration, obstruction, and survival between groups.ConclusionBig funnel stents and individualized stents resulted in similar shaping effect and prevention of stent migration and obstruction, suggesting that funnel shaped stents can be used to treat cup or funnel shaped GOO caused by distal stomach cancer.

Project description:Metabolic surgery has been increasingly recommended for obese diabetic patients, but questions remain as to its effectiveness for nonobese diabetic patients and its mechanism that leads to glucose homeostasis independently of weight loss. Roux-en-Y gastric bypass (RYGB), as one of the most effective metabolic operations, excludes a portion of stomach with the proximal intestine (biliopancreatic limb, BL) and rearranges the distal end of the intestine into a Y-configuration, in which food can flow from the upper stomach pouch through the Roux limb (RL). To address the above questions to RYGB surgery, we designed a series of surgical procedures in Goto-Kakizaki （GK） rats to assess the relationship between glycemic control independent of weight loss and RL length in the RYGB procedure and studied the molecular mechanism of the RL from a systematic and comprehensive view.

Project description:ObjectivesCombined biliary obstruction and gastric outlet obstruction (GOO) represent a challenging clinical scenario despite developments in therapeutic endoscopic ultrasonography (EUS) as GOO might impair EUS-guided biliary drainage. Little is known about the effectiveness of different therapeutic combinations used to treat double obstruction, especially regarding stent patency.MethodsAll consecutive patients with double obstruction treated between 2016 and 2021 in three tertiary academic centres were eligible for inclusion. Five combinations involving enteral stenting (ES), EUS-guided gastroenterostomy (EUS-GE), hepaticogastrostomy (EUS-HGS), choledochoduodenostomy (EUS-CDS), and transpapillary biliary stenting (TPS) were evaluated for dysfunction during follow-up, either as proportions or dysfunction-free survival (DFS) using Kaplan-Meier estimates.ResultsNinety-three patients were included (male 46%; age 67 [interquartile range 60-76] years; pancreatic cancer 73%, metastatic 57%), resulting in 103 procedure combinations. Different combinations showed significantly different overall dysfunction rates (p = 0.009), ranging from the null rate of EUS-GE+HG to the 18% rate of EUS-GE+TPS, 31% of EUS-GE+EUS-CD, 53% of ES+TPS and 83% of ES+EUS-CDS. Sub-analyses restricted to biliary dysfunction confirmed these trends. A multivariate Cox proportional-hazards regression of DFS, a stenosis distal to the papilla (HR 3.2 [1.5-6.9]) and ES+EUS-CDS (HR 5.6 [2-15.7]) independently predicted dysfunction.ConclusionsDespite a lack of statistical power per combination, this study introduces new associations beyond the increased risk of GOO recurrence with ES versus EUS-GE. EUS-CDS showed reduced effectiveness and frequent dysfunction in the context of GOO, especially when combined with ES. EUS-GE+HGS or EUS-GE+TPS in this setting might result in superior patency. These results suggest that a prospective evaluation of the optimal endoscopic approach to malignant double obstruction is needed.

Project description:Analysis of changes in gene expression after weight loss. The hypothesis tested in this study was that the weight loss caused by Roux-en-Y Gastric bypass may alter the expression of genes involved in multiple molecular pathways related to obesity. The results will generate important data for studies involving treatment of obesity, which is characterized as a multifactorial disease that affects thousands of individuals worldwide.

Project description:BackgroundExclusion of the stomach after Roux-en-Y gastric bypass (RYGB) makes access to the biliary tree very challenging for the surgeon or the endoscopist. Different techniques have been described to overcome this downside, including laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (ERCP), which is an outstanding method to access the remnant stomach in order to reach the duodenal papilla. The use of this technique is associated with a high success rate.Presentation of caseHere we present the case of a 57-year-old patient with altered RYGB anatomy. The patient underwent laparoscopic cholecystectomy. Intraoperative cholangiography revealed the presence of a stone in the common bile duct. A laparoscopy-assisted transgastric ERCP was performed successfully. During the procedure, the duodenoscope was introduced through a gastrostomy, obviating the need for an intragastric trocar. The patient evolved favorably and was discharged on second postoperative day without any complications.DiscussionTransgastric laparoscopy-assisted ERCP represents an effective approach for the management of biliary complications after RYGB, even if there is a long interval between the two interventions, as occurred in the present case. Other methods described for accessing the biliary tree in patients with altered RYGB anatomy are double-balloon ERCP and endoscopic ultrasound-directed transgastric ERCP. We elected to perform the laparoscopy-assisted approach because choledocholithiasis was diagnosed transoperatively, thus, avoiding the need for secondary procedures or interventions.ConclusionTransgastric laparoscopy-assisted ERCP is a feasible procedure with low complication rates and is used in treating patients with altered RYGB anatomy who present with biliary tract disorders. The use of transgastric laparoscopy-assisted ERCP allows endoscopic treatment and cholecystectomy to be performed in a single setting.

Project description:BACKGROUND:Gastric cancer is an extremely rare condition to occur after bariatric surgery, and most of the reported cases are adenocarcinomas. Regarding gastrointestinal stromal tumors (GISTs), there are only two reported cases occurring after bariatric surgery (one after gastric banding and the other following Roux-en-Y gastric bypass (RYGB)). CASE PRESENTATION:A 48-year-old woman with previous history of obesity and type 2 diabetes, treated with a Roux-en-Y gastric bypass 2 years earlier, was referred to our center due to complains of diffuse abdominal pain and distension associated with asthenia. Magnetic resonance imaging showed a cystic-solid mass located in the right hypochondrium, measuring 19.5 × 13.5 × 16 cm, suggesting the diagnosis of a retroperitoneal tumor. Based on these findings, a laparotomy, evidencing that the larger cystic-solid tumor was originating from the excluded stomach post-RYGB. The gastrectomy of the excluded stomach was performed aside with a conventional cholecystectomy. Histopathology and immunohistochemistry confirmed to be a gastric GIST with epithelioid cells. Currently, 12 months after surgery, the patient presents no signs of recurrence. CONCLUSION:This is the second case of gastric GIST occurring after RYGB to be reported in the literature.
