BACKGOUND/AIMS: The involvement of bile ducts is frequently reported in autoimmune pancreatitis (AIP), which seem to have similar features to primary sclerosing cholangitis (PSC). Recent systematic comparative studies about these diseases are rare in Korea. METHODS: We retrospectively analyzed 26 patients with AIP with bile duct involvement and 30 patients with classic PSC who were diagnosed during the last decade. RESULTS: The mean age of patients was significantly higher in AIP than PSC at the time of diagnosis. There was a preponderance of men in both group, which was more prominent in AIP. The most common symptom in patients with AIP was jaundice, but PSC patients usually visited hospitals due to incidentally detected abnormal liver function tests. Most (26/31) of AIP had bile duct involvement. All of these patients showed narrowing of intrapancreatic common bile ducts and one patient exhibited hilar involvement as well. About 80% of PSC had both intra- and extrahepatic ducts involvement, and the characteristic features involve multifocal strictures. AIP patients showed improvement with steroid treatment, however, most PSC patients showed clinical deterioration. CONCLUSIONS: The clinical and cholangiographic findings of patients with AIP and PSC have many different characteristics. Therefore, further study of two diseases is required for the proper diagnosis and management.

Afferent loop syndrome is a rare complication which can occur in patients with Billroth II gastrectomy. Bile and pancreatic juice is congested at afferent loop in the syndrome. This syndrome can progress rapidly to necrosis, perforation, or severe sepsis, and therefore early diagnosis and swift surgical intervention is important. But, cases of endoscopic or percutaneous transhepatic drainage have been reported when surgical management was inappropriate to proceed. We report a case of afferent loop syndrome accompanying acute cholangitis developed after percutaneous transhepatic cholangioscopic lithotripsy for the retrieval of common bile duct stone in a patient who underwent Billroth II gastrectomy due to early gastric cancer. There was no other organic cause. We treated afferent loop syndrome successfully by performing balloon dilation of afferent loop outlet.
