Background: Patients with cholestatic liver function tests and histological features of primary scleroslng cholangitis (PSC) but a normal cholangiogram are considered to have small duct PSC. The natural history of this condition is unknown. Methods: Thirty three patients with small duct PSC were identified among patients admitted for diagnostic workup of cholestatic liver function tests in one centre in the UK (Oxford) and one centre in Norway (Oslo). A total of 260 patients with large duct PSC were compared, and prognosis in terms of death, cholangiocarcinoma, biochemical features, histological features, and symptoms analysed. Results: Mean age at diagnosis was 38 years and 39 years in small duct and large duct PSC, respectively. Mean follow up was 106 months in small duct and 105 months in large duct patients. Four patients originally considered to have small duct developed large duct PSC. Two of these underwent liver transplantation during follow up. Of the remainder who did not develop large duct PSC, two patients died during follow up: one of liver failure and the other of cardiac death unrelated to her liver disease. A total of 122 (47%) large duct patients either required liver transplantation (34 patients) or died (88 patients). Small duct patients had a significantly better survival compared with large duct patients. Among small duct patients, none developed cholangiocarcinoma compared with 28 of 260 (11%) large duct patients. Conclusions: Patients with small duct PSC seem to have a good prognosis in terms of survival and development of cholangiocarcinoma. Small duct PSC progresses to large duct PSC in a small proportion of patients. [ABSTRACT FROM AUTHOR]

Twelve of 178 (7%) liver transplant patients underwent endoscopic retrograde cholangiopancreatography (ERCP) after transplantation. The indications for ERCP were persistent or late onset cholestasis, recurrent cholangitis, and suspected biliary leaks or strictures. The time between transplantation and ERCP ranged from 44 to 330 days (median 153 days). Biliary complications diagnosed by ERCP included biliary sludge in the form of casts, calculi, or debris (n = 7); bile leaks (n = 2); a biliary stricture (n = 1), and complete biliary obstruction (n = 1). One patient had a normal cholangiogram after transplantation. Biliary sludge was detected by ultrasound before ERCP in only one of six patients. Eight patients underwent endoscopic papillotomy, followed by clearance of biliary sludge in four and dilatation of a biliary stricture in one. Two patients bled after papillotomy but neither required surgical intervention. At a median follow up of 1.2 years (range 0.5-2.8 years), nine patients are well and three have died. ERCP provides both accurate diagnosis of biliary complications after liver transplantation and treatment that obviates the need for additional surgery in selected patients. [ABSTRACT FROM PUBLISHER]

Primary sclerosing cholangitis (PSC), present in 5% of patients with ulcerative colitis, may be associated with pouchitis after ileal pouch-anal anastomosis. The cumulative frequency of pouchitis in patients with and without PSC who underwent ileal pouch-anal anastomosis for ulcerative colitis was determined. A total of 1097 patients who had an ileal pouch-anal anastomosis for ulcerative colitis, 54 with associated PSC, were studied. Pouchitis was defined by clinical criteria in all patients and by clinical, endoscopic, and histological criteria in 83% of PSC patients and 85% of their matched controls. PSC was defined by clinical, radiological, and pathological findings. One or more episodes of pouchitis occurred in 32% of patients without PSC and 63% of patients with PSC. The cumulative risk of pouchitis at one, two, five, and 10 years after ileal pouch-anal anastomosis was 15.5%, 22.5%, 36%, and 45.5% for the patients without PSC and 22%, 43%, 61%, and 79% for the patients with PSC. In the PSC group, the risk of pouchitis was not related to the severity of liver disease. In conclusion, the strong correlation between PSC and pouchitis suggest a common link in their pathogenesis.

The aetiological role of biliary lithiasis for chronic pancreatitis remains controversial. Previous studies based on pancreatographic studies reported changes in the pancreatic duct system caused by biliary lithiasis. This study analysed retrospectively the endoscopic retrograde cholangiopancreatography of 165 patients presenting with biliary lithiasis and of 53 controls. Among the 165 patients, 113 had choledochal stones (53 with gall bladder stones, 50 had had a cholecystectomy, 10 with a normal gall bladder), 35 had gall bladder stones without choledochal stones, 17 had cholecystectomy for gall bladder stones. Pancreatograms were analysed by measuring the diameter of the pancreatic duct in the head, the body, and the tail of the pancreas, and evaluating the regularity of the main pancreatic duct and the presence of stenosis, the regularity or the dilatation of secondary ducts, and the presence of cysts. In addition, we established a score, based on the above parameters, by which pancreatograms were classified as normal or with mild, intermediate, moderate or severe abnormalities. A multivariate analysis (stepwise multiple discriminant analysis) was performed for age, sex, presence of gall stones, presence of choledochal stones. Patients were comparable with controls for sex, alcohol consumption but were younger (55 v 68 years, p < 0.01). In patients and in controls, the frequency of pancreatographic abnormalities increased significantly with age. The pancreatographic features of patients and controls were not significantly different. In the multivariate analysis, age was the only factor with significant predicting value for pancreatographic abnormalities. In conclusion, biliary lithiasis in itself is not an aetiological factor for chronic pancreatitis, older age being responsible for the abnormalities seen by pancreatography of patients with biliary lithiasis.

A case control study of AIDS related sclerosing cholangitis indicates that it has no overall influence on prognosis, but is responsible for a striking reversal of the usual inverse correlation of age and survival in HIV infection. Pain, the principal symptom, was controlled in surviving patients with analgesics alone. Twenty consecutive patients with AIDS related sclerosing cholangitis, defined from at least two characteristic lesions at endoscopic retrograde cholangiopancreatography, were followed for a minimum of 10 months or until death. Median age was 33.5 years (range 27-50). All had abdominal pain; 11 had diarrhoea. Alkaline phosphatase was > 2X normal in 13, but the bilirubin was raised in only three. The median CD4 was 0.024 x 10(9)/l (0.005-0.341). Thirteen had cryptosporidiosis, six had active cytomegalovirus, five had no gastrointestinal pathogen. Three patients are alive without AIDS related sclerosing cholangitis symptoms at 10, 11, and 21 months. Seventeen have died at median 7 (1-23) months. Cytomegalovirus therapy had no apparent influence. The initial CD4 was < 0.11 in all those dying within six months, but correlation of CD4 with prognosis was otherwise poor. Controls, matched for age, CD4, and opportunistic infections had virtually identical overall outcome (median survival 7.5 months) and the expected worse prognosis with increasing age. Increasing age, however, appeared protective in AIDS related sclerosing cholangitis (r = +0.6; p < 0.05): this is not explained by disproportionate degrees of immunosuppression, nor by opportunistic infections.

Obstructive jaundice caused by compression of the common hepatic duct by a simple hepatic cyst in a 31 year old Europid man is reported. The jaundice and duct compression resolved after percutaneous aspiration of the cyst under ultrasound direction and the patient has been well for 12 months. [ABSTRACT FROM PUBLISHER]
