[Evaluation of endoscopic sphincter of Oddi manometry in patients with biliopancreatic diseases].

Diagnostic ability of endoscopic sphincter of oddi manometry for 112 patients with biliopancreatic diseases (including 12 patients of normal) was evaluated. The presence of abnormal high pressure was recognized in 50% of suspected sphincter of oddi dysfunction (SOD). 56% of cholecystolithiasis, 67% of cholecystocholedocholithiasis and 50% of pancreatic stones. Many patients with abdominal pain of suspected SOD or stones of biliopancreatic ducts were considered to have possibility of the complication of papillary stenosis. It was thought that endoscopic sphincter of oddi manometry was a useful method of confirming the presence of SOD.
