RETRACTED ARTICLE: Different anesthesia methods for laparoscopic cholecystectomy

Abstract

The aim of the study was to compare the possibility of performing laparoscopic cholecystectomy using two different anesthesia procedures (spinal anesthesia versus general anesthesia). The study included 68 patients with symptoms of cholelithiasis examined in the 309th Hospital of PLA from 2006 to 2009. Patients were randomly selected to undergo laparoscopic cholecystectomy with low tension pneumoperitoneum with CO(2) under general anesthesia (n=33) or spinal anesthesia (n=35). The study used propofol, fentanyl, rocuronium, sevoflurane and tracheal intubation for general anesthesia and hyperbaric 15mg bupivacaine and 20µg fentanyl were used to achieve a sensorial level of T(3) for spinal anesthesia. Intraoperative parameters, postoperative pain, complications, recovery, patient satisfaction and cost were compared between both groups. All surgical procedures were completed with the chosen method with the exception of one case, in which spinal anesthesia was converted to general anesthesia. Shoulder pain was significantly less frequent in the spinal anesthesia group (6%) compared with the general anesthesia group (24%). The level of pain at 2, 4, and 6h after the procedure under spinal anesthesia was significantly lower than that under general anesthesia. At 12h both groups had the same evaluation in the visual analogue scale. In the spinal anesthesia group all patients recovered 6h after surgery, while patients in the general anesthesia group spent more time in recovery. All patients were discharged from hospital after 24h. In the postoperative evaluation all patients were satisfied with the spinal anesthesia and would recommend this procedure, while only 78.9% of patients were very satisfied in the general anesthesia group. The cost of spinal anesthesia was significantly lower than that of general anesthesia. Laparoscopic cholecystectomy with low pressure pneumoperitoneum with CO(2) can be safely performed under spinal anesthesia. Spinal anesthesia was associated with an extremely low level of postoperative pain, better recovery and lower cost than general anesthesia.
