Abstract

PURPOSE
Recently, single-incision laparoscopic surgery (SILS) has been popular for minimally invasive surgery and cosmetic improvement. However, some papers have reported that SILS for an appendectomy (SILS-A) has had the more postoperative complaints of pain. We investigated postoperative pain relief using wound infiltration with 0.5% bupivacaine in SILS-A and compared the result with that for conventional SILS-A.
METHODS
Between July 2010 and September 2012, 75 patients who underwent SILS-A were enrolled in this study. The patients were randomly assigned to two groups: conventional SILS-A group (C-SILS-A) or wound infiltrated with 0.5% bupivacaine in SILS-A group (W-SILS-A). Forty-five patients were in the C-SILS-A, and 30 patients were in the W-SILS-A. Patients with perforated appendicitis were excluded. The clinical outcomes were compared between the groups by using the verbal numerical rating scale (VNRS).
RESULTS
Clinical outcomes were similar in both study groups except for the pain score. The W-SILS-A group showed significantly lower numbers of additional pain killers and lower VNRS scores 1, 6, and 12 hours after surgery than the C-SILS-A group.
CONCLUSION
W-SILS-A is a technically simple and effective method of reducing early postoperative pain. It may be applicable in SILS-A for pain control system.
