title: Biliary colic without evidence of gallstones: diagnosis, biliary lipid metabolism and treatment.
abstract: Fifteen patients with history of biliary colic, induceable by cholecystokinin, but normal oral cholecystogram and ultrasonogram were studied prior to and after cholecystectomy. Fasting duodenal bile, obtained preoperatively after administration of cholecystokinin, and gallbladder bile obtained at operation were analyzed. The lipid composition as well as the cholesterol saturation were within the range seen in gallstone-free subjects. The total lipid concentration of gallbladder bile was normal, whereas that of duodenal bile was reduced by about 50%, indicating a less efficient gallbladder emptying. In 10 of the 15 patients, the analysis of the excised gallbladder displayed macro- or microscopic abnormalities; two patients had cholesterol gallstones. At re-examination 9-27 months after the operation, 12 of the patients were completely symptom-free and two patients reported a clear improvement while on still had unchanged symptoms. It is concluded that cholecystectomy is the treatment to prefer in patients with "acalculous" biliary pain, induceable by cholecystokinin.
