Laparo-endoscopic single-site (LESS) cholecystectomy with epidural vs. general anesthesia.
BACKGROUND: Laparo-endoscopic single-site (LESS) surgery involves a single umbilical incision, lending itself to epidural anesthesia. This prospective, randomized study was undertaken to evaluate epidural anesthesia for patients undergoing LESS cholecystectomy, to assess the feasibility, and to analyze all intraoperative and postoperative complications. The secondary objectives were to determine differences in postoperative pain and time until PACU discharge-to-home readiness between patients. METHODS: With institutional review board approval, 20 patients with chronic cholecystitis, cholelithiasis, and/or biliary dyskinesia were randomized to receive spinal epidural anesthesia (n = 10) or general anesthesia (n = 10). Postoperative pain at rest was recorded in the PACU every 10 min, and at rest and walking at discharge using the visual analog scale (VAS). Operative time and time until PACU discharge-to-home readiness were recorded. Results are expressed as mean ± SD. RESULTS: Patient age, American Society of Anesthesiologists class, and body mass index were similar. There were no additional ports/incisions, conversions to "open" operations, or conversions to general anesthesia. There were no differences in operative duration. Time until postanesthesia care unit discharge-to-home ready was not significantly different. The most common postoperative adverse event was urinary retention (1 epidural and 3 general anesthesia patients). Resting postoperative VAS pain score at discharge was 4.7 ± 2.5 vs. 2.2 ± 1.6 (p = 0.02, general versus epidural anesthesia respectively); the stressed VAS pain score at discharge was 6.1 ± 2.3 vs. 3.1 ± 2.8 (p = 0.02, general versus epidural anesthesia respectively). CONCLUSIONS: LESS cholecystectomy with epidural anesthesia was completed with no operative or anesthetic conversions, and less postoperative pain at discharge. Epidural anesthesia appears to be a preferable alternative to general anesthesia for patients undergoing LESS cholecystectomy.
