Abstract

Choledochoscopy is effective in reducing the incidence of retained biliary stones and for the removal of retained calculi through the T-tube tract. It has also been of value in performing complex reconstructive and diversionary procedures on the common duct. Knowledge of the biliary anatomy is a prerequisite for the development of skill in choledochoscopy. The use of a biliary endoscopy teaching model with stones has been very effective in teaching the techniques of biliary endoscopy. Experience with the choledochoscope and its accessories should precede its use for postoperative choledochoscopy.

Endoscopic sphincterotomy in young patients with choledochal dilatation and a long common channel: a preliminary report.

An anomalous elongated pancreaticobiliary common channel encourages reflux up both the biliary tree and the pancreatic ductal system, resulting in progressive choledochal dilatation, cholangitis with ductal calculi, relapsing pancreatitis and malignant change. Transduodenal sphincteroplasty has been used to improve drainage from the abnormal channel. The use of endoscopic sphincterotomy (ES) to establish drainage and minimize the surgical risks is reported in six symptomatic patients with mild choledochal dilatation (common bile duct diameter less than 15 mm), a common channel less than 15 mm in length and a distal stenosis. This was successful in five patients, who have no further symptoms. ES failed in the only patient with an undilated common channel and this patient went on to have open surgery. We believe ES to be safe and effective in the treatment of selected cases of long common channel.
