Randomized Controlled Trial Multicenter StudyEffect of staple height on gastrojejunostomy during laparoscopic gastric bypass: a multicenter prospective randomized trial.
Gastrointestinal (GI) bleeding and anastomotic stricture are frequent complications associated with the construction of the gastrojejunostomy during laparoscopic gastric bypass. Staplers with shorter staple height can reduce the rate of postoperative GI hemorrhage. The aim of the present study was to assess the outcomes of patients who had undergone gastric bypass with construction of the gastrojejunostomy using a 25-mm circular stapler with a 3.5- versus 4.8-mm staple height. ⋯ 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.
