Abstract In experimental animals, sphincterotomyfacilitates passage of solids from the gallbladder andinhibits gallstone formation apparently by improvementin gallbladder emptying. In humans, however, gallbladder emptying has not been studied followingendoscopic sphincterotomy (ES) in patients withgallstones. We therefore prospectively studied restingand cerulinstimulated gallbladder volumes by real timeultrasonography in 15 patients of choledocholithiasis withgallbladder in situ (eight with and seven withoutgallbladder calculi) before and after (after bile ductclearance) ES. ES significantly lowered restinggallbladder volume (21.2 ± 10.6 vs 11.1 ±5.0; P 〈 0.0001) and cerulin-stimulated residualgallbladder volume (10.8 ± 5.6 vs 4.4 ±2.1; P 〈 0.0001). ES also significantly increased thegallbladder ejection fraction (47.3 ± 12.1% vs 58.8 ± 11.1%; P 〈 0.0001). Therate constant for gallbladder emptying after cerulininfusion also increased significantly after ES(–0.022/min vs –0.031/ min; P 〈 0.0001).Significant improvement in gallbladder motility was observed in both groups ofpatients with and without gallbladder calculi. ESsignificantly improves gallbladder motility inhumans.
