Acute gallstone pancreatitis

Abstract

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.
