Background: Revising the size of the gastric pouch during the conversion of one anastomosis gastric bypass (OAGB)/mini-gastric bypass to Roux-en-Y gastric bypass (RYGB) is an important point. Even in patients undergoing RYGB, marginal ulcer is regarded as a known complication. Materials and Methods: In our Centre of Excellence in Bariatric and Metabolic Surgery, 2492 patients underwent OAGB from February 2012 to January 2019. Twelve of 2492 patients were enrolled in this clinical case series because of persistent gastroesophageal reflux-like symptoms which underwent conversional RYGB. All patients regularly received proton-pump inhibitors (PPIs) for 6 months after the surgery. After this period, the cases with symptomatic reflux were invited to be visited in the clinic by a bariatric surgeon and a gastroenterologist and received 6 months of PPI therapy until their symptoms disappeared. Twelve refractory reflux cases underwent conversional RYGB after 1 year. An enteroenterostomy was created in all the patients 75 cm distal to the gastrojejunostomy without resizing the gastric pouch, and the jejunal loop was cut just before the gastrojejunostomy. Results: Before conversional surgery, mean ± standard deviation (SD) body mass index (BMI) and gastroesophageal reflux disease (GERD)-Q score were found to be 26.45 ± 2.34 kg/m 2 and 10.08 ± 0.56, respectively. At 1 year after conversion, mean ± SD BMI in the patients was 28.12 ± 4.71, and GERD-Q score was 5.08 ± 1.5. Conclusion: It seems that resizing the gastric pouch is not necessary during the conversion of OAGB to RYGB.

“…Gastric bypass surgery is a safe, effective treatment for individuals with severe obesity [ 1 ] and leads to improvements in associated conditions including type 2 diabetes mellitus (T2DM) [ 2 ] and cardiovascular disease [ 3 ]. The most frequently performed procedure is the Roux-en-Y gastric bypass (RYGB), and more recently the One-Anastomosis gastric bypass (OAGB) which are equally effective for both weight loss [ 4 ] cardiovascular and quality-of-life outcomes [ 5 , 6 ] .…”

Gastric bypass surgery leads to significant and sustained weight loss and a reduction in associated health risks in individuals with severe obesity. While reduced energy intake (EI) is the primary driver of weight loss following surgery, the underlying mechanisms accounting for this energy deficit are not well understood. The evidence base has been constrained by a lack of fit-for-purpose methodology in assessing food intake coupled with follow-up studies that are relatively short-term. This paper describes the underlying rationale and protocol for an observational, fully residential study using covert, objective methodology to evaluate changes in 24-hr food intake in patients (n = 31) at 1-month pre-surgery and 3-, 12- and 24-months post-surgery, compared to weight-stable controls (n = 32). The main study endpoints included change in EI, macronutrient intake, food preferences, and eating behaviours (speed, frequency, and duration of eating). Other physiological changes that may influence EI and weight regulation including changes in body composition, circulating appetite hormones, resting metabolic rate, total energy expenditure and gastrointestinal symptoms were also evaluated. Understanding which mechanisms contribute to a reduction in EI and weight loss post-surgery could potentially help to identify those individuals who are most likely to benefit from gastric bypass surgery as well as those that may need more targeted intervention to optimise their weight loss post-surgery. Furthermore, clarification of these mechanisms may also inform targeted approaches for non-surgical treatments of obesity.
