Acute gallstone pancreatitis -: Timing of laparoscopic cholecystectomy in mild and severe disease

Background: In acute gallstone pancreatitis, the ideal point in time for laparoscopic cholecystectomy with special reference to the severity of the disease has been prospectively analyzed. Methods: A total of 77 patients with biliary acute pancreatitis were admitted between November 1993 and July 1998 (37 men and 40 women; mean age, 63 years; median Apache II score, 13.3) and staged by contrast-enhanced computed tomography findings as having edematous or necrotizing disease. Results: In 48 patients, laparoscopic cholecystectomy was found to be possible: 35 patients (73%) with mild and 13 patients (27%) with severe acute pancreatitis. The overall success rate was 79% (38 of 48 patients), with 85% (30 of 35 patients) and 62% (8 of 13 patients) having mild and severe disease, respectively. Median duration of time between onset of symptoms and surgery was 10 days (range, 4-19 days) in edematous and 14 days (range, 7-29 days) in necrotizing pancreatitis (p = 0.0353). Operating time (median, 80 min) and hospital stay (median, 5 days) were almost the same in both groups. Total morbidity was 8%, with no mortality. Conclusions: Laparoscopic cholecystectomy with preoperative endoscopic common bile duct clearance is recommended as a treatment of choice for biliary acute pancreatitis. In mild disease, this is performed safely within 7 days, whereas in severe disease, especially in extended pancreatic necrosis, at least 3 weeks should elapse because of an increased infection risk.
