Bariatric surgery is a well-tolerated and effective treatment for severe obesity. Newer surgical techniques and equipment have improved safety standards surrounding bariatric surgery. In particular, buttressing of the staple line in sleeve gastrectomy has decreased rates of clinically significant postoperative bleeding. The present study investigates the effectiveness of buttressing the circular stapled anastomosis during laparoscopic Roux-en-Y gastric bypass (LRYGB).
