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.

Urinary retention in common benign anal surgery is a burden to ambulatory surgery.
PURPOSE: To reduce voiding complication pudendal nerve block (PB) was applied in hemorrhoids surgery. METHODS We compared PB with spinal anesthesia (SA) for anal surgery. In this prospective study, 163 patients undergoing elective hemorrhoids surgery by single surgeon were randomized to receive either PB with 0.5% bupivacaine (n=81) with 1: 20,000 epinephrine or SA with 0.5% bupivacaine (n=83). RESULTS There were no statistically significant differences in patient demographics, total amount of administered fluid, time to onset of block, or intraoperative pain. All patients had a successful block for surgery however, puborectalis muscle relaxation with PB was not complete. The time from injection of the anesthetics to first development of pain was longer in the patients who received PB (9.1 vs 3.1h; P<0.001). Urinary catheterization needed in only 6 patients in PB group compared with 57 cases in SA group (p<0.001).
Degree of pain was significantly low in PB (2.7 vs 5.2 with VAS; p<0.001) Injected analgesics was significantly reduced in PB (16/81 vs 45/82; p<0.001) CONCLUSIONS: Our results suggest that PB with bupivacaine results in fewer postoperative voiding complications and less pain compared with traditional SA in hemorrhoidectomy.
BACKGROUND /AIMS: The caudal anesthsia is most commonly used for benign anorectal surgery, The combination of long-acting anesthetics and opiates has been used for longer duration and successful control of postoperative pain. But the side effects of peridural anesthesics and morphine have commonly occured in caudal anesthesia. This study was performed to assess the difference in clinical effects between peridural mepivacaine and bupivacaine with morphine. METHODS We evaluated the clinical effects in 60 patients who had anal operation with Jack-Knife position under caudal anesthesia. We divided randomly these 60 patients into two groups, M and B groups (in each group, 30 patients included). Group M (n=30) was given 2% mepivacaine 20 ml with morphine 2 mg caudally, and Group B (n=30) was given 0.5% bupivacaine 20 ml with morphine 2 mg in the same manner. We measured the onset time, duration, postoperative analgesia, and side effects including urinary retention. RESULTS The onset time for analgesia was significantly shorter in group M than in group B. The duration of postoperative pain complaints was significantly longer in group M than in group B. The postoperative analgesic effects and side effects were not significantly different between two groups. CONCLUSIONS Caudal mepivacaine and morphine mixture is effective for control of postoperative pain without significant side effects.
