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)...

INTRODUCTION: Effect of bariatric surgery on health-related quality of life (HRQOL) varies greatly. This might be caused by the diversity in questionnaires used to assess HRQOL and the weight loss of the studied population. This study assesses the relationship between weight loss and HRQOL in primary Roux-en-Y gastric bypass (RYGB) patients by using an obesity-specific (impact of weight on quality of life-lite, IWQOL-lite) and a generic (RAND-36) questionnaire. METHODS: HRQOL and weight parameters were assessed before and 15 and 24 months after RYGB surgery...

BACKGROUND: Concerns for the possibility of an excessive loss of fat-free mass (FFM) and resting metabolic rate (RMR) after bariatric surgery, such as Roux-en-Y gastric bypass (RYGB) and duodenal switch (BPD/DS), have been raised. OBJECTIVES: This study aims to examine body composition and RMR in patients after RYGB and BPD/DS and in non-operated controls. METHODS: Body composition and RMR were studied with Bod Pod and indirect calorimetry in weight-stable RYGB (n = 15) and BPD/DS patients (n = 12) and compared with non-operated controls (n = 17)...

Up to 50% of patients have zinc deficiency before bariatric surgery. Roux-en-Y gastric bypass (RYGB) is the commonest bariatric procedure worldwide. It can further exacerbate zinc deficiency by reducing intake as well as absorption. The British Obesity and Metabolic Surgery Society, therefore, recommends that zinc level should be monitored routinely following gastric bypass. However, the American guidance does not recommend such monitoring for all RYGB patients and reserves it for patients with 'specific findings'...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is the most effective method for the treatment of obesity, and metabolic disease RYGB may reduce body weight by altering the feeding responses evoked by the short-term satiety peptides. MATERIALS AND METHODS: Here, we measured meal size (MS, chow), intermeal interval (IMI) length, and satiety ratio (SR, IMI/MS; food consumed per a unit of time) by the small and the large forms of gastrin-releasing peptide (GRP) in rats, GRP-10 and GRP-29 (0, 0...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is complicated by a leak in 0-4.3% of cases. Treatment by fully covered stents has been reported to be associated with some life-threatening complications. We report our experience of insertion of double pigtail stents. METHODS: Thirty-three patients (20M, 43 years-20/65), presenting with a leak at an average of 10 days after RYGB (4-35), were treated by double pigtail stent insertion and a nasojejunal feeding tube. Sixty percent of these patients had undergone surgical drainage prior to stenting for control of sepsis...

INTRODUCTION: Morbidly obese patients have lower quality of life (QOL) when compared to the general population. So far, no studies have compared gender and procedural differences in gastrointestinal QOL after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). METHODS: Patients before and after bariatric surgery completed the gastrointestinal quality of life index (GIQLI), a 36-item questionnaire with five subscores. Differences between SG and RYGB were analyzed, as were gender differences...

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: Few population-based studies provide data on mortality after bariatric surgery. We hypothesized that hypoglycemia could be an underdiagnosed cause of death. OBJECTIVES: To examine perioperative, all-cause, and cause-specific long-term mortality in Roux-en-Y gastric bypass (RYGB) patients versus population comparisons. SETTING: Danish nationwide population-based cohort study. METHODS: We included all 9895 patients who underwent RYGB during 2006-2010, and a 1:25 age- and gender-matched comparison cohort (n = 247,366) (0...

BACKGROUND: Bariatric surgery has increased in popularity, with Roux-en-Y Gastric Bypass (RYGB) being one of the most frequently performed. This leads to many cases in which the stomach is removed from routine gastroscopy access, sometimes being a major source of concern. Performing enteroscopy in these patients is technically difficult. We present our experience with 24 cases in which the aim was to access the detached stomach. METHODS: Retrospective analysis on RYGB enteroscopy procedures aimed to access the detached stomach...

Bariatric surgery is associated with bone loss but skeletal consequences may differ between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), the two most commonly performed bariatric procedures. Furthermore, severe weight loss is associated with high marrow adipose tissue (MAT); however, MAT is also increased in visceral adiposity. The purpose of our study was to determine the effects of RYGB and SG on BMD and MAT. We hypothesized that both bariatric procedures would lead to a decrease in BMD and MAT...

Roux-en-Y gastric bypass (RYGB) is an efficient treatment for morbid obesity and reduces obesity-related co-morbidities. With the growing number of patients undergoing gastric bypass, complications now demand further attention. Postprandial hyperinsulinemic hypoglycemia (PHH) after Roux-en-Y gastric bypass is a complex condition, characterized by increased glucose variability including both hyperglycemic and hypoglycemic values. PHH seems to be more prevalent than previously suggested and is highly dependent on the choice of diagnostic tool, which has not yet been standardized...

OBJECTIVE: Although long-term weight regain may occur after bariatric surgery, many patients are protected against relapse or development of type 2 diabetes. The study objective was to investigate whether this involves beneficial changes in adipose function. RESEARCH DESIGN AND METHODS: Forty-nine obese women were investigated before and 2 and 5 years after Roux-en-Y gastric bypass (RYGB). At the 5-year follow-up, 30 subjects were pairwise matched for BMI and age to 30 control women...
