AIMS: To achieve additional weight loss or to resolve band-related problems, a laparoscopic adjustable gastric banding (LAGB) can be converted to a laparoscopic Roux-en-Y gastric bypass (RYGB). There is limited data on the feasibility and safety of routinely performing a single-step conversion. We assessed the efficacy of this revisional approach in a large cohort of patients operated in a high-volume bariatric institution. METHODS: Between October 2004 and December 2015, a total of 885 patients who underwent LAGB removal with RYGB were identified from a prospectively collected database...

BACKGROUND: Robust data on quality of life (QoL) after different techniques of bariatric surgery are sparse. This RCT compared excess weight loss (EWL) and QoL after sleeve gastrectomy versus Roux-en-Y gastric bypass (RYGB). METHODS: Obese patients were assigned randomly to RYGB or sleeve gastrectomy. The primary outcome measure was EWL. Secondary outcomes included QoL, co-morbidity, adverse events, vitamin and glycolipid status. QoL was assessed before and annually after surgery, using the Moorehead-Ardelt Quality of Life Questionnaire II (M-A-QoLQII) and Gastrointestinal Quality of Life Index (GIQLI)...

BACKGROUND: Bariatric surgery (BS), the most effective treatment for severe obesity, typically results in 40-50 kg weight loss in the year following the surgery. Beyond its action on protein metabolism, dietary protein intake (PI) affects satiety, thermogenesis, energy efficiency, and body composition (BC). However, the required amount of PI after surgical weight loss is not known. The current daily PI recommendation for diet-induced weight loss is 0.8 g/kg ideal body weight (IBW) per day, but whether this amount is sufficient to preserve fat-free mass during active surgical weight loss is unknown...

Type 2 diabetes (T2D) in Asian populations is characterized by a lower body mass index (BMI) than in Caucasian cases. This pilot study investigated antidiabetic outcomes after a Roux-en-Y gastric bypass (RYGB) in Asian subjects with T2D and BMI < 30. Fifteen Koreans with poorly controlled T2D and BMI 23-30 underwent RYGB. Two years after RYGB, seven patients achieved HbA1c < 6.5% without medication (target-achieved). The other cases also showed improved glycemic control. The insulin secretory response during an oral glucose tolerance test was significantly restored in the target-achieved group...

BACKGROUND: Preservation of pancreatic beta cell function has been increasingly appealing in the treatment of type 2 diabetes. Evidence is still limited on how bariatric surgery affects pancreatic beta cell apoptosis. SETTING: University medical center. OBJECTIVE: The study aimed to investigate the effect of a major component of Roux-en-Y gastric bypass, duodenal-jejunal bypass, on protecting pancreatic beta cells from progressive loss. METHODS: Forty-five normal Sprague-Dawley rats were randomly assigned into 3 groups: duodenal-jejunal bypass (DJB) group (n = 16) and sham (S) group (n = 17), based upon the procedure received, and a control (C) group (n = 12) without any procedure performed, to eliminate potential traumatic effects from surgery...

BACKGROUND & AIMS: Marginal ulceration, or ulceration at the gastrojejunal anastomosis, is a common complication of Roux-en-Y gastric bypass (RYGB). Acidity likely contributes to the pathophysiology, and proton pump inhibitors (PPIs) frequently are prescribed for treatment. However, patients with gastric bypass only have a small gastric pouch and rapid small-bowel transit, which limits the opportunity for capsule breakdown and PPI absorption. Soluble PPIs (open capsules [OCs]) might be absorbed more easily than intact capsules (ICs)...

One of the most effective methods to tackle obesity and its related comorbidities is bariatric surgery. Polycystic ovary syndrome (PCOS) and endometrial hyperplasia (EH), which are associated with increased risk of endometrial carcinoma, have been identified as potentially new indications for bariatric surgery. PCOS is the most common endocrine disorder in women in the reproductive age and is associated with several components of the metabolic syndrome such as obesity, insulin resistance and hypertension. EH is a pre-cancerous condition which arises in the presence of chronic exposure to estrogen unopposed by progesterone such as both in PCOS and obesity...

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...
