A double-blinded, prospective randomized controlled trial of intraperitoneal bupivacaine in laparoscopic Roux-en-Y gastric bypass.

Background: Intraperitoneal local anesthetics have been investigated in several laparoscopic procedures that demonstrate improved postoperative pain control and reduced length of hospital stay. No published studies to date address the effectiveness of IP local anesthetics in laparoscopic gastric bypass patients (LRYGB).

Study Design: Between October 2004 and March 2005, 133 patients were prospectively studied to evaluate the efficacy of IP bupivacaine (IPB) in LRYGB.
