[Management of asymptomatic lithiasis].

A careful analysis of the series of patients with asymptomatic gallstones suggests that prophylactic cholecystectomy is not necessary. The purpose of this work was to try to detect subgroups of asymptomatic patients with factors predictive of symptoms or of severe complications such as acute cholecystitis, pancreatitis, or gallbladder carcinoma. Among local factors, neither the size, number or nature of gallstones, nor alterations of the walls or contractility of the gallbladder were predictive of symptoms or complications. Among general factors, neither the age or sex of patients nor associated diseases such as diabetes mellitus or recent organ transplantation were predictive of symptoms or complications. Only the few patients with a porcelain gallbladder were at high risk for gallbladder carcinoma requiring prophylactic cholecystectomy. In all other patients treatment of asymptomatic gallbladder stones is unnecessary as well as any surveillance.
