title: [Transduodenal sphincteroplasty of the Oddi-Boyden for free bilio-pancreatic flow].
abstract: In 58 patients we performed transduodenal sphincteroplasty to show the effectiveness of this procedure in patients with stenosis of the sphincter of Oddi-Boyden, choledocholithiasis and biliary pancreatitis with follow up ranging from 14 months to 11 years 3 months. The sphincteroplasty was performed in 33 cases (27%) for stenosis, in 13 cases (22%) for biliary pancreatitis and in 12 cases (12%) for choledocholithiasis. All cases with the exception of one had cholelithiasis or choledocholithiasis. In 39 patients (67%) the cholangiography performed before the sphincteroplasty demonstrated a common bile duct with average diameter of 1.6 cm. On the first, third and fifth postoperative examination of serum bilirubin and amylase showed a progressive decrease, implying free flow through the common bile duct. Post operative cholangiography confirmed free flow of contrast trough the common bile duct into the duodenum (p < 0.05). The morbidity and mortality were 24.5% and 1.7% respectively. The results were bad in 2 cases, fair in one case, and excellent in 55 cases (94.6%); which were completely free of symptoms postoperatively. We conclude that transduodenal sphincteroplasty of the sphincter of Oddi-Boyden is a useful procedure to reestablish free biliary flow in cases of stenosis, choledocholithiasis and biliary pancreatitis.
