Influence of pouch and stoma size on weight loss after gastric bypass

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

“…The findings of the present study are in accordance with this since, except in the very early postoperative phase, no correlation between staple line length and %EBMIL was found, in spite of the very large study group. Contrary to this, Heneghan et al [20] noted that large pouches are more common in patients suffering from weight regain; however, it is unknown whether a large pouch allows big meals or whether the pouch becomes enlarged because of overeating. Finally, age and high BMI are known to predict inferior EBMIL% [21,22] as well as the presence of diabetes [22].…”

Increased Gastric Retention Capacity, Assessed by Scintigraphy, after APC Treatment of Dilated Gastrojejunal Anastomosis

“…The causes of this weight regain are numerous, but they include metabolic dysfunctions, relaxed diets, a sedentary lifestyle, hormonal changes, fistulas, a large stomach pouch, and dilatation of the gastrojejunal anastomosis [3-6]. In fact, dilatation of the gastrointestinal anastomosis is one of the most common causes [7, 8]. …”

Six month outcomes in patients experiencing weight gain after gastric bypass who underwent gastrojejunal revision using an endoluminal suturing device

“…A recent multicenter randomized trial demonstrated that dilation of the gastrojejunal (GJ) anastomosis has been associated with weight regain after surgery [9,10]. In this trial, endoscopically reducing the diameter of the GJ stoma resulted in additional weight loss after RYGB [11].…”
