Several studies indicate a causal relationship between duodenal diverticula and gallstone disease. The diverticula persist after biliary tract surgery, and it is therefore presumed that patients with diverticula have an increased disposition to develop new calculi in the bile ducts after cholecystectomy. To test this hypothesis, the occurrence of recurrent biliary calculi was studied in 101 patients who had cholecystectomy, all with an asymptomatic period of two years or more following the primary biliary surgery. All patients had symptoms, that indicated biliary tract or pancreatic diseases. The incidence of recurrent calculi in patients with diverticula was 87.5% (95% confidence interval, 66.9–95.8). In patients without diverticula, the incidence was 31.9% (95% confidence interval, 21.5–44.3). The difference is highly significant, and the results support the assumption tht diverticula in the area of the papilla of Vater dispose to gallstone disease.
