title: [Stenosing odditis: diagnosis and treatment. Report of 109 cases (author's transl)].
abstract: Stenosing odditis represents only 4.5 p. cent of all benign lesions of the extrahepatic bile ducts. Their diagnosis is made by peroperative radiomanometry, but clinically they are suggested by a past history and serious clinical signs. The pancreatic involvement is rarely macroscopic (10 p. cent of cases of which 5 p. cent are severe) and acute pancreatitis due to stricture of the sphincter without gall stones is exceptional. Associated biliary lesions are frequent; in 50 p. cent of cases, of lithiasis of the common bile duct or pancreatitis, in 66 p. cent of cases of residual odditis. The treatment is surgical. Sphincterotomy should be reserved for young subjects with a slightly dilated common bile duct, or when necessary to extract a gall stone from the lower end of the bile duct. Biliary by pass operations are all the more indicated when the patient is elderly or the common bile duct more dilated. Local complications are the most frequent and the most serious after sphincterotomy; the local complications of biliary by pass operations are usually very simple. The late results of biliary by-pass operations are better than those of sphincterotomy, which confirms that the pancreatic complications of odditis are rare or well tolerated. The presence of chronic pancreatitis in association is not an aggravating factor.
