The Effect of Stoma Size on Weight Loss After Laparoscopic Gastric Bypass Surgery: Results of a Blinded Randomized Controlled Trial

Abstract

The level of restriction or the presence of stenosis achieved by different circular stapler sizes does not have a significant causative role in weight loss.

Circular- vs. Linear-Stapled Gastrojejunostomy in Laparoscopic Roux-En-Y Gastric Bypass

“…Gould et al [23] found a significantly reduced incidence of anastomotic strictures using the 25-mm circular stapler compared to the 21-mm circular stapler, but no negative influence of the wider anastomosis on the EWL at 1 year. Both results correlate to the findings of Nguyen et al [24] and Cottam et al [25].…”

The Use of Predictive Markers for the Development of a Model to Predict Lowest Quartile Weight Loss following Roux-en-Y Gastric Bypass.

“…In 2009 we also found that the only significant effectors of weight loss at one year were gender and BMI (26). This study correlates directly with our results that other factors are not significant in predicting excess weight loss at one year.…”

“…Literature is also split of whether age effects weight loss however we did not find it to be significant (7,23 paper (26) and this one as well.…”

Importance of pouch size in laparoscopic Roux-en-Y gastric bypass: a cohort study of 14,168 patients

“…The importance of the size of the gastric pouch and the gastrojejunostomy, for long-term weight loss, has been debated since the very start of bariatric surgery. Stoma size has been shown in several studies to be of importance for gastroplasties [15,16], but not for RYGB [17,18]. The first pouches in gastric bypass had a volume of about 200 ml, according to the inventor Dr Mason [19], and were vertically orientated, containing a large part of the greater curvature, prompt for later dilatation.…”
