[Alternative endobiliary operations for choledocholithiasis and papilla of Vater stenosis]

The immediate results of endoscopic papillosphincterotomy (EPST) (n=754) and endobiliary balloon dilatation (n=120) were comparatively analyzed. Survey included patients with choledocholithiasis and papilla Vateri stenosis. The use of balloon dilatation and EPST was defined by the size and amount of gallstones. Balloon dilatation was preferable when there less then 3 concrements. "Critical" diameter of the gallstone, which permitted the use of endobiliary dilatation, was 9 mm. In cases of the papilla Vateri stenosis balloon dilatation also demonstrated better results then EPST: 93,5+/-3,6% and 79,4+/-2,8% of satisfactory results, respectively).
