Pathogenesis of acute cholecystitis after gastrectomy.

Abstract

The increased incidence of gallbladder diseases after gastrectomy is discussed with regard to contractile motility of the gallbladder. Ultrasonographic findings and contraction of the gallbladder in response to egg yolk or caerulein were studied before and after gastrectomy at intervals ranging from 2 weeks to 6 months. Enlargement of the gallbladder with accumulation of biliary sludge and hypomotility were frequently observed within a month of operation for gastric cancer, suggesting that biliary stasis is an important contributing factor in postoperative acute cholecystitis. Within 3 months of operation, contraction had recovered to close to preoperative levels and the incidence of biliary sludge formation gradually decreased. Daily administration of an opiate antagonist, naloxone (0.8 mg), significantly improved gallbladder dyskinesia and decreased the incidence of biliary sludge formation within 1 month of gastrectomy.
