Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of pulmonary function and postoperative pain after laparoscopic versus open gastric bypass: a randomized trial.
Impairment of pulmonary function is common after upper abdominal operations. The purpose of this study was to compare postoperative pulmonary function and analgesic requirements in patients undergoing either laparoscopic or open Roux-en-Y gastric bypass (GBP). ⋯ Laparoscopic gastric bypass resulted in less postoperative suppression of pulmonary function, decreased pain, improved oxygenation, and less atelectasis than open gastric bypass.
