simplified gastric bypass

Rui He, Yue Yin, Yin Li, Ziru Li, Jing Zhao, Weizhen Zhang
BACKGROUND: Despite of its significant therapeutic effects on obesity and metabolic diseases, Roux-en-Y gastric bypass (RYGB) has limited clinical application because of considerable impacts on the gastrointestinal structure and postoperative complications. This study aims to develop a simplified surgical approach with less damage and complication but efficient metabolic benefit. METHODS: The effects of Esophagus-Duodenum gastric bypass (EDGB) on body weight, food intake, glucose and lipid metabolism were compared to RYGB in mice...

Obesity and its associated comorbidities entail a significantly increased cardiovascular mortality. Therefore, approaching obesity control must include among its aims the reduction of the associated comorbidities and the higher cardiovascular mortality risk and not only weight loss. Many observational studies indicate that bariatric surgery (BS) is associated with a better long-term survival than standard care. Furthermore, in general, these epidemiological studies included patients who underwent gastric bypass (GB), not biliopancreatic diversion/duodenal switch (BPD/DS), so the potential additional benefit of this latter technique remains unknown...

Background: Gastric bypass is a restrictive and malabsorptive surgery. The restrictive part consists in the creation of a small gastric pouch. The gastrointestinal bypass serves as the malabsorptive element. Aim: To describe a simplified gastric bypass approach for morbid obese patients, showing our results, and also remarking the importance of this technique for reducing the learning curve. Method: The patient is positioned in a split legs position and carefully strapped to the operating room table, with the surgeon between the patient's legs...

Severe nutrition complications after bariatric surgery remain poorly described. The aim of this case series was to identify specific factors associated with nutrition complications after bariatric surgery and to characterize their nutrition disorders. We retrospectively reviewed all people referred to the clinical nutrition intensive care unit of our university hospital after bariatric surgery from January 2013 to June 2015. Twelve persons who required artificial nutrition supplies (ie, enteral nutrition or parenteral nutrition) were identified...

BACKGROUND: The Roux-en-Y gastric bypass (GBP) has been considered the gold standard for many years. The loop duodenal switch (LDS) is a relatively new procedure that simplifies the complexity of the duodenal switch (BPDDS) by making it a single anastomosis procedure while at the same time giving it more intestinal absorption to reduce the rates of malnutrition associated with traditional BPDDS. This paper seeks to compare the 18-month weight loss outcomes and complications of the more standard GBP with the newer LDS in a single US center...

BACKGROUND: Laparoscopic gastric bypass is one of the most performed bariatric operations worldwide. The exclusion of stomach and duodenum after this operation makes the access to the biliary tree, in order to perform an endoscopic retrograde cholangiopancreatography (ERCP), very difficult. This procedure could be more often required than in overall population due to the increased incidence of gallstones after bariatric operations. Among the different techniques proposed to overcome this drawback, laparoscopic access to the excluded stomach has been described by many authors with a high rate of success reported...

BACKGROUND: Obesity surgery includes various gastrointestinal procedures. Roux-en-Y gastric bypass is the prototype of mixed procedures being the most practiced worldwide. A similar and novel technique has been adopted by Dr. Almino Cardoso Ramos and Dr. Manoel Galvao called "simplified bypass," which has been accepted due to the greater ease and very similar results to the conventional technique. The aim of this study is to describe the results of the simplified gastric bypass for treatment of morbid obesity in our institution...

BACKGROUND: The surgical management of complex or morbid obesity is increasing exponentially. Laparoscopic procedures are being increasingly utilized due to their similar efficacy but shorter hospital stay and faster convalescence when compared with open surgery. Despite this, many patients remain in hospital for a number of days after laparoscopic obesity surgery due to concerns about potential sequelae. We present the results of our simplified fast-track service, designed to enable discharge of all patients on postoperative day one following laparoscopic Roux-en-Y gastric bypass (LRYGB)...

BACKGROUND: Intestinal anastomosis is a complex procedure during laparoscopy, mainly due to the difficulties knotting the sutures. Unidirectional barbed sutures have been proposed to simplify wall and mesentery closure, but the results for intestinal anastomosis are not clear. This study aimed to establish the feasibility and the safety of laparoscopic intestinal anastomosis using barbed suture. METHODS: Between June 2011 and May 2012, 15-cm-long unidirectional absorbable barbed sutures (V-Loc; Covidien, Mansfield, MA, USA) were used for all laparoscopic intestinal anastomoses: one suture for closure of intestinal openings after mechanical anastomoses and two sutures for hand-sewn anastomoses...

INTRODUCTION: Vertical banded gastroplasty (VBG) originated as a simplified bariatric operation to avoid malabsorption and provide lasting results due to a fixed stoma. Short-term results were excellent (50-70 % excess weight loss); however, patients often displayed maladaptive eating behaviors, and many failed to either achieve or sustain adequate long-term weight loss. Complications were also common including severe reflux and regurgitation, gastric outlet stenosis or stricture, gastrogastric fistula, and breakdown of the staple line...

BACKGROUND: Although the mortality from bariatric surgery is low, perioperative determinants of morbidity and mortality in the bariatric surgery population to date have not been fully defined. This study aimed to evaluate the factors capable of predicting perioperative mortality based on preoperative characteristics with a national patient sample. METHODS: From the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, all the primary bariatric procedures performed between 2007 and 2009 were identified...

The past decade has seen an enormous increase in the number of bariatric, or weight loss, operations performed. This trend is likely to continue, mirroring the epidemic of obesity around the world and its rising prevalence among children. Bariatric surgery is considered by many to be the most effective treatment for obesity in terms of maintenance of long-term weight loss and improvement in obesity-related comorbid conditions. Although overly simplified, the primary mechanisms of the surgical interventions currently utilized to treat obesity are the creation of a restrictive or malabsorptive bowel anatomy...

OBJECTIVES: Due to the multi-factorial physiological implications of bariatric surgery, attempts to explain trends in oral bioavailability following bariatric surgery using singular attributes of drugs or simplified categorisations such as the biopharmaceutics classification system have been unsuccessful. So we have attempted to use mechanistic models to assess changes to bioavailability of model drugs. METHODS: Pharmacokinetic post bariatric surgery models were created for Roux-en-Y gastric bypass, biliopancreatic diversion with duodenal switch, sleeve gastrectomy and jejunoileal bypass, through altering the 'Advanced Dissolution Absorption and Metabolism' (ADAM) model incorporated into the Simcyp® Simulator...

BACKGROUND: Bowel obstruction due to internal hernia is a well-known complication of laparoscopic Roux-en-Y gastric bypass (LRGB). Increasing evidence supports primary closing of the mesenteric defects, but controversy continues about surgical technique of systematic closure. This paper reviews our experience with internal hernia after LRGB and describes a new method of preemptive closure of the mesenteric defects. MATERIAL AND METHODS: Two thousand four hundred seventy-two consecutive patients undergoing LRGB from September 2005 to June 2010 were entered into our prospective longitudinal database...

Small bowel obstruction (SBO) after bariatric surgery is well documented. Although infrequent, it can be associated with considerable morbidity and mortality. The laparoscopic approach to Roux-en-Y gastric bypass (LRYGB) has gained widespread popularity for the treatment of morbid obesity since its first description in 1994. One of the theoretical advantages of a minimally invasive technique is reduced intraabdominal adhesions and, consequently, diminution in the incidence of SBO. However, the laparoscopic approach demonstrates a similar rate of obstruction to the open procedure...
