title: Effect of cisapride on symptoms and biliary drainage in patients with postcholecystectomy syndrome.
abstract: The study evaluates the effect of 20 mg cisapride twice daily on symptoms and biliary drainage in patients with the postcholecystectomy syndrome. Nineteen patients, all female, went through a randomized, double-blind, placebo-controlled, crossover trial with two 4-week treatment periods separated by a 2-week washout period. Symptoms were registered on diary cards. Biliary drainage was studied with dynamic cholescintigraphy. The down slope of the time-activity curve (T1/2 and elimination index) was used as a measure of the biliary drainage. More symptoms were registered during cisapride therapy than with placebo. This unfavourable effect of cisapride was statistically significant in a subgroup of patients with postcholecystectomy complaints identical to the biliary pain they experienced during injection of contrast at the endoscopic retrograde cholangiopancreatographic examination. Cisapride statistically significantly hastened biliary drainage. The median T1/2 values were 24 and 28 min after cisapride and placebo, respectively (p less than 0.01). In conclusion, cisapride promoted biliary drainage in patients with the postcholecystectomy syndrome but had an unfavourable symptomatic effect in those with bile duct-triggered postcholecystectomy complaints.
