A case of common bile duct stones successfully treated by endoscopic papillary balloon dilation using straight view scope with a transparent hood attached to the tip, following Billroth II gastrectomy

Abstract

A 58-year-old male visited our hospital due to severe epigastric pain. Twentyseven years ago, he received distal partial gastrectomy due to duodenal ulcer. A common bile duct (CBD) stone was detected at abdominal CT scanning. We performed endoscopic retrograde cholangiopancreatography (ERCP) with side view scope, but approach to the afferent loop failed. Thus, we changed side view scope to straight view scope with a transparent hood attached to the tip, and this made access to the papilla of Vater, handling of a catheter and its cannulation to CBD very smooth. Endoscopic papillary balloon dilation (EPBD) was performed leading to successful removal of stone. Our experience indicated that EPBD with straight view scope using a transparent hood attached to the tip is useful for the treatment of CBD stones following Billroth II gastrectomy.
