Abstract:
The objective of the study was to investigate the accuracy of using preoperative data for the prediction of bile duct calculi in patients operated on for acute cholecystitis. 279 consecutive patients underwent cholecystectomy with peroperative cholangiography for acute calculous cholecystitis in the Department of Surgery, Lund University Hospital, between 1985 and 1991. The correlation between 13 preoperative clinical and laboratory variables, and the incidence of bile duct calculi was studied. Among the 13 variables tested, serum bilirubin concentration and serum gamma-glutamyltransferase activity were independent factors of predictive significance. These two factors were used for constructing an additive prognostic index for the presence of bile duct stones. Thus, three groups of patients could be identified having a 3, 7-9 or 59% risk of harboring bile duct stones, corresponding to a sensitivity of 61% and a specificity of 93% in predicting the presence of bile duct stones in the 'high-risk' group. Logistic regression analysis permits accurate preoperative identification of bile duct stones in patients with acute calculous cholecystitis.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
