Randomized Controlled Trial Multicenter StudyIncidence of gastroenterostomy stenosis in laparoscopic Roux-en-Y gastric bypass using 21- or 25-mm circular stapler: a randomized prospective blinded study.
Laparoscopic Roux-en-Y gastric bypass is the most common bariatric procedure performed in the United States today. The most common early complication after laparoscopic Roux-en-Y is stenosis. No randomized studies have compared the effect of the different staplers on the incidence of stenosis or on long-term weight loss. We compared the anastomoses performed with the two sizes of circular stapler in common use. ⋯ We found a significant difference in the stenosis rate between the 21-mm and 25-mm circular stapled anastomoses in laparoscopic Roux-en-Y gastric bypass. The 21-mm staplers led to significantly more endoscopies than did the 25-mm staplers. Symptoms leading to endoscopy occurred significantly later with use of a 25-mm stapler than after a 21-mm stapler.

Randomized Controlled TrialLaparoscopic adjustable gastric banding versus Roux-en-Y gastric bypass: 5-year results of a prospective randomized trial.
To perform a prospective, randomized comparison of laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB). ⋯ The results of our study have shown that LRYGB results in better weight loss and a reduced number of failures compared with LAGB, despite the significantly longer operative time and life-threatening complications.
