Abstract
The knowledge about how patients are selected for elective gallbladder investigations is limited. In this study the anamnestic data of 817 patients referred for an elective cholecystography have been compared with those of 789 matched controls. Other diseases in the medical history were commonly seen, and different gastrointestinal symptoms occurred frequently in the patients. Only 207 (23%) patients presented with a gallstone disease, and no symptom was commoner in these patients than in the patients with normal cholecystograms. The low positive yield could be due to liberal and unclear indications for oral cholecystography. Many gallstones detected this way may in fact be asymptomatic, which should be borne in mind when a cholecystectomy is considered.
