Abstract:
Objective To explore the relationship between the histological alterations of Oddi sphincter lesions and clinical manifestations. MethodsFrom October 1995 to May 2003, biopsies of Oddi sphincter were undertaken during transduodenal sphincteroplasty (TSP) in 32 cases. Specimens were stained with Van Gieson Mason staining. ResultsThirty one out of 32 specimens were found with histological alterations in Oddi sphincter including diffuse fibrosis in 87 1% (27/31) , adenomyosis in 2 cases and chronic inflammatory infiltration in 2 cases. Impacted stone in the terminal common bile duct, benign papillary stenosis and visible postpancreatitis parenchymal changes were all found accompanying severe fibrosis of Oddi sphincter. ConclusionIn patients with impacted stones in the ampulla, intracholedochal sludge with recurrent cholangitis, and relapsing pancreatitis, endoscopic sphincterotomy is recommended.
