Laparoscopic surgery has become an acceptable alternative for open surgery in treating benign gynecologic diseases. One of most important advantages of laparoscopy is a reduced postoperative pain compared with open surgery. Moreover, postoperative pain plays an important part in the enhanced recovery after surgery (ERAS) pathway. Although the length of hospitalization and recovery period after laparoscopy tends to be shorter, postoperative pain can still be an important issue.~Recently, continuous wound infusion (CWI) providing a constant flow of local anesthetic directly a surgical wound postoperatively has been widely used to reduce pain after cesarean section and open surgery. Studies evaluating the effectiveness of CWI to manage postoperative pain following laparoscopy are markedly lacking. Especially, there was no study comparing CWI and placebo in treating gynecologic laparoscopy. Therefore, the investigators conducted this randomized, double-blind, placebo-controlled trial to investigate whether CWI of local anesthetics was an effective strategy for ERAS, compared with placebo in patients undergoing benign gynecologic laparoscopy.
