A comparison of bupivacaine lavage and diclofenac suppository effects on post-operative pain of laparascopic transabdominal pre-peritoneal herniorrhaphy: a randomized clinical trial study.

Objectives: Injection of a topical anaesthetic has been proved to be helpful with reducing pain after laparoscopic herniorrhaphy. We aimed to assess the effect of bupivacaine lavage on postoperative pain and compare it with diclofenac suppository. In this randomized clinical trial, 60 patients-scheduled for laparoscopic herniorrhaphy-were enrolled and randomized into three groups of 20 each, including diclofenac suppository, bupivacaine lavage, and normal saline as a placebo.
