Effect of staple height on gastrojejunostomy during laparoscopic gastric bypass: a multicenter prospective randomized trial

In the present prospective, randomized trial, using a circular stapler with a shorter staple height (3.5 mm) during construction of the gastrojejunostomy, significantly reduced the rate of postoperative anastomotic stricture, with a trend toward a lower rate of GI bleeding from the gastrojejunostomy.
