Cholangiography

Abstract: Twenty-nine patients with primary sclerosing cholangitis were reviewed. Males predominated (2:1). Seventy-six per cent presented with cholestasis and cholangitis, 17% with cirrhosis and portal hypertension, and 7% were asymptomatic, presenting with a raised serum alkaline phosphatase. The serum immunoglobulin IgM concentration was raised in 45% of the patients, but no patient had serum mitochondrial antibody present. Seventy-two per cent had ulcerative proctocolitis. There was no relationship between either duration or severity of ulcerative proctocolitis and the development of primary sclerosing cholangitis. Four patients were not benefited by colectomy. None of the patients ahd Crohn's disease. The prognosis was variable. Corticosteriods and azathioprine were ineffective. Eleven patients (38%) had died with a mean survival time of seven years from diagnosis. Three patients with ulcerative proctocolitis developed bile duct carcinoma. The cholangiograms and liver biopsies were reported without reference to clinical information together with 41 patients with other biliary diseases. Cholangiography was diagnostic in 18/22 (82%). Hepatic histology was diagnostic in 8/22 (36%). Ten showed features of large bile duct disease and three were misdiagnosed as primary biliary cirrhosis. Reduced numbers of bile ducts, ductular proliferation, portal inflammation, and substantial copper deposition, in combination with piecemeal necrosis, are commonly seen in primary sclerosing cholangitis and indicate the need for cholangiography.

Abstract: The last 30 years have seen major developments in the management of gallstone-related disease, which in the United States alone costs over 6 billion dollars per annum to treat. Endoscopic retrograde cholangiopancreatography (ERCP) has become a widely available and routine procedure, whilst open cholecystectomy has largely been replaced by a laparoscopic approach, which may or may not include laparoscopic exploration of the common bile duct (LCBDE). In addition, new imaging techniques such as magnetic resonance cholangiography (MR) and endoscopic ultrasound (EUS) offer the opportunity to accurately visualise the biliary system without instrumentation of the ducts. As a consequence clinicians are now faced with a number of potentially valid options for managing patients with suspected CBDS. It is with this in mind that the following guidelines have been written.

Abstract: In patients with obstructive jaundice caused by malignant stricture of the extrahepatic bile duct we compared survival time, complication rates, hospitalisation requirements, and quality of life after palliation by endoscopic endoprosthesis or bypass surgery. During diagnostic endoscopic cholangiography 50 patients were randomised to the two treatment alternatives. All 25 patients randomised to endoprosthesis were treated by this procedure, whereas only 19 of 25 patients randomised to bypass surgery underwent operative biliary-digestive anastomosis. Life table analysis revealed no difference in survival between treatment groups or randomisation groups. No differences were found when other variables were compared. We conclude, that palliation of obstructive jaundice in malignant bile duct obstruction with endoscopically introduced endoprosthesis is as effective as operative bypass.
