Benign non-traumatic inflammatory strictures of the extrahepatic biliary system

Abstract

Obstructive jaundice was the presenting feature in 12 patients with benign, non-traumatic strictures of the extrahepatic bile ducts. Ages at presentation ranged from 1.5 to 60 years and 11 were initially referred with diagnoses of malignant strictures. Histological examination, however, showed benign changes of chronic inflammation, with ulceration in seven, which were distinct from those of primary sclerosing cholangitis. All of the patients remain well from 3 to 14 years after surgery. The aetiology of the strictures is not known.
