Abstract
Gallstones in western countries are primarily composed of cholesterol. However, mixed or pigment stones, which contain a higher proportion of bilirubin, are more frequently seen in developing nations and Asia than in western countries. Abdominal and shoulder tip pains (STPs) are common complaints following the standard laparoscopic cholecystectomy procedure. To date, all pain management modalities have proven variable outcomes. This prospective randomized study included 82 patients who underwent elective laparoscopic cholecystectomy. The control group received 20 mL of normal saline, whereas the study group received a 20-mL instillation of 0.5% bupivacaine at the gallbladder bed after surgical resection. The Visual Analog Scale (VAS) was used to analyze abdominal pain and STP. The mean age ranged from 20 to 80 years. Abdominal VAS at 6, 12, 18, 24, 30, 36, and 48 hours were statistically insignificant. The majority were discharged on postoperative day 1 (32 studies, 37 control). Follow-up VAS after 1 week for STP VAS and abdominal pain VAS in both groups were statistically insignificant. Even with small numbers of a well-conducted randomized trial, we demonstrated that bupivacaine irrigation at the gallbladder bedpost laparoscopic cholecystectomy does not affect pain relief.
