BACKGROUND: Excellent results have been reported with mini-gastric bypass. We adopted and modified the one-anastomosis gastric bypass (OAGB) concept. Herein is our approach, results, and long-term follow-up (FU). METHODS: Initial 1200 patients submitted to laparoscopic OAGB between 2002 and 2008 were analyzed after a 6-12-year FU. Mean age was 43 years (12-74) and body mass index (BMI) 46 kg/m(2) (33-86). There were 697 (58 %) without previous or simultaneous abdominal operations, 273 (23 %) with previous, 203 (17 %) with simultaneous, and 27 (2 %) performed as revisions...

BACKGROUND AND AIMS: Unsatisfactory weight loss after gastric bypass or sleeve gastrectomy in super-obese patients (body mass index > 50) is a growing concern. Biliopancreatic diversion with duodenal switch results in greater weight loss, but is technically challenging to perform, especially as a laparoscopic procedure (Lap-DS). The aim of this study was to compare perioperative outcomes of Lap-DS and the corresponding open procedure (O-DS) in Sweden. MATERIAL AND METHODS: The data source was a nationwide cohort from the Scandinavian Obesity Surgery Registry and 317 biliopancreatic diversion with duodenal switch patients (mean body mass index = 56...

BACKGROUND: The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are current therapeutic options to reverse the hypoglycemic effect, with substantial associated morbidity. Our group reports a pilot clinical series of a novel surgical technique using one-anastomosis jejunal interposition with gastric remnant resection (Branco-Zorron Switch)...

OBJECTIVES: Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedure. One anastomosis gastric bypass (OAGB) is rapidly emerging as a safe and effective metabolic procedure. This study aims at comparing the 1-year follow-up results of OAGB and LSG in terms of excess weight loss, complications, resolution of comorbidities, and quality of life. METHODS: A prospective randomized study of results between 100 LSG and 101 OAGB patients was done from 2012 to 2015...

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...

Background: Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. Aim: To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Methods: Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients...

BACKGROUND: In one anastomosis gastric bypass (OAGB), the measurement of the afferent limb starting at the angle of Treitz may result in insufficient absorptive surface of the intestine of the remaining efferent limb. To address this concern, we recently modified the technique of OAGB by constructing the gastrointestinal anastomosis at a fixed distance from the ileocecal valve (i.e., 300 cm). We adopted the new concept and named it the single anastomosis gastro-ileal bypass (SAGI). METHODS: Seven consecutive patients with morbid obesity underwent the SAGI procedure...

The technically easier one-anastomosis (mini) gastric bypass (MGB) is associated with similar metabolic improvements and weight loss as the Roux-en-Y gastric bypass (RYGB). However, MGB is controversial and suspected to result in greater malabsorption than RYGB. In this study, we compared macronutrient absorption and intestinal adaptation after MGB or RYGB in rats. Body weight and food intake were monitored and glucose tolerance tests were performed in rats subjected to MGB, RYGB, or sham surgery. Carbohydrate, protein, and lipid absorption was determined by fecal analyses...

BACKGROUND: This video demonstrates laparoscopic band-separated one anastomosis gastric bypass-combining the advantages of banding and gastric bypass without stapler and cutter use. This is basically a gastrojejunal loop bypass above an obstructive band in the upper stomach. MATERIALS AND SURGICAL TECHNIQUE: An adjustable low pressure "Medsil" gastric band was introduced in the abdomen and retracted through the retrogastric tunnel. The front wall of the stomach below the band was displaced in the upward direction through the ring band, increasing the size of the anterior portion of the stomach pouch so that a gastroenteroanastomosis could be created at this point...

BACKGROUND: Obesity is the most frequent chronic metabolic disease globally. There is a direct correlation between increasing body mass index (BMI) and elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and triglycerides (Tg), and an inverse correlation with high-density lipoprotein cholesterol (HDL); all these lipid derangements are associated with an increased risk of cardiovascular disease. Our aim was to evaluate lipid profiles in morbidly obese patients before and after one-anastomosis gastric bypass (OAGB) performed at a single-center during a 2-year follow-up...

BACKGROUND: Gastric bypass procedures can potentially lead to middle and long-term complications (Podnos et al. Arch Surg 138(9):957-61, 2003). For several years, Roux-en-Y gastric bypass reversal procedures performed by laparotomy or laparoscopic way have been described in literature (Moon et al. Surg Obes Relat Dis 11(4):821-6, 2015). Major complications are anastomotic ulcers, anastomotic complications or functional disorder such as dumping syndrome, hypocalcemia, severe hypoglycemia, and malnutrition (Moon et al...

BACKGROUND: Insufficient weight loss (percentage of excess weight loss [%EWL]<50%) is observed in approximately 20% of patients after Roux-en-Y gastric bypass (RYGB). Surgical revision can be performed by various procedures including malabsorptive techniques. Conversion to a biliopancreatic diversion with duodenal switch (BPD/DS) remains a complex technique which cannot always be performed as a one-stage procedure. OBJECTIVES: This study evaluates the conversion of RYGB to BPD/DS using a novel gastric reconstruction technique based on a "hybrid sleeve" using the existing gastrojejunal anastomosis of the RYGB...

INTRODUCTION: Roux-en-Y gastric bypass is a commonly used technique of bariatric surgery. One of the most important complications is gastrojejunal anastomotic stricture. Endoscopic balloon dilation appears to be well tolerated and effective, but well-designed randomized, controlled trials have not yet been conducted. OBJECTIVE: Identify factors associated with complications or failure of endoscopic balloon dilation of anastomotic stricture secondary to Roux-en-Y gastric bypass surgery...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most performed bariatric procedures in treating morbid obesity. There is no consensus on which technique used for gastrojejunal anastomosis is optimal. The meta-analysis aimed to solve the issue by comparing hand-sewn with mechanical gastrojejunostomy during LRYGB for morbid obesity. METHODS: PubMed, Embase, Cochrane Library, Scopus, Google Scholar and Research Gate were searched (from inception to April 2016)...

Management of super-super obese patients poses a particular challenge for bariatric surgeons. Many staged algorithms exist for these patients. Essentially all of these involve a lower-risk procedure like sleeve gastrectomy first before a definitive second-stage procedure like gastric bypass or duodenal switch. This study compares our results with 19 mini (one anastomosis) gastric bypass and 56 sleeve gastrectomy in super-super obese patients. Sleeve gastrectomy patients were significantly older. There was no mortality or major complication in either group...

Surgery continues to be the mainstay of esophageal cancer treatment. However, it is a big challenge for the surgical treatment of patients with both esophageal cancer and coronary artery disease (CAD). We reported, here, the first case series of esophageal cancer patients treated with simultaneous esophagectomy and off-pump coronary artery bypass grafting (CABG). From August 2010 to August 2012, 2154 esophageal or esophageal gastric junction (EGJ) cancer patients underwent surgical treatment in Tangdu Hospital, Xi'an, China...

BACKGROUND: The improvement in glucose metabolism after bariatric surgery is well established. The aim of this study was to investigate the hormones and glycemic control in diabetes after a one-anastomosis gastric bypass (OAGB) variant in an animal model of non-obese type 2 diabetes mellitus. METHODS: Thirty-six Goto-Kakizaki rats were randomly assigned to undergo one of the following procedures: OAGB (18 rats) or sham intervention (18 rats). Each group was subdivided into three additional groups according to the time of surgery (early-12 weeks; intermediate-16 weeks; and late-20 weeks)...
