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.
