CLINICAL INVESTIGATION OF JUXTA-PAPILLARY DIVERTICULA

-THE INFLUENCE ON PANCREATICO -BILIARY DISEASE AND EST-

Abstract

Twelve thousand and twenty five cases of ERCP and 254 cases EST were performed since 1978 at our institute. We have investigated on the incidence and influence of juxta papillary diverticula in our cases which performed ERCP or EST. One hundred seventy six out of 1225 cases (14.4%) performed ERCP were complicated with diverticula. Especially, it was seen frequently in the cases of bile duct stone or benign papillary stenosis. Many of those diverticula were located at supra-papillary, and a few of them were seen at infra-papillary region. In 7 out of 43 cases with juxta-papillary diverticula EST was limited on the width and the direction of cutting. All cases of recurrent stones in our EST had juxta-papillary diverticula. EST is often interrupted by complicated juxta-papillary diverticula, but it is necessary for such cases to be cut as widely and carefully as possible.
