Hepatobiliary disorders occur frequently in patients with IBD, with PSC and cholangiocarcinoma being the most clinically significant for endoscopists. Endoscopic therapy for PSC is effective in improving symptoms, biochemical parameters, and radiographic abnormalities. Endoscopic therapy may also confer survival benefit, but this has yet to be confirmed in randomized, controlled trials. Treatment should be restricted to those individuals with a rapid decline in liver function testing or those with recurrent cholangitis. Cholangiocarcinoma is a serious complication of PSC and carries an extremely poor prognosis. ERCP with brush cytology has a relatively low sensitivity and the diagnosis is usually made after the disease has become metastatic. Malignant biliary obstruction can be palliated by endoscopic stenting. Photodynamic therapy is a promising experimental technique that may confer symptomatic and survival benefit in patients with nonresectable, advanced cholangiocarcinoma. IBD patients also have an elevated risk for developing acute and chronic pancreatitis as well as pancreatic insufficiency. The majority of cases of acute pancreatitis are likely due to medication side effects and local structural complications of IBD. The remainder may possibly represent true extraintestinal manifestations of IBD. Chronic pancreatitis is frequently subclinical, but may be accompanied by clinically relevant exocrine insufficiency. ERCP is the test of choice for the diagnosis of chronic pancreatitis, but the role of endoscopy in the therapeutic management of IBD-associated chronic pancreatitis remains to be defined.

Sclerosing cholangitides represent a group of chronic biliary obstructive diseases which include primary sclerosing cholangitis (PSC), IgG4 associated sclerosing cholangitis (IgG4-SC) and secondary sclerosing cholangitis (SSC). The manifestations of the diseases are similar, but their asymptomatic course is also frequent. IgG4-SC belongs to the group of IgG4 associated diseases and it is the most frequently related to type 1 autoimmune pancreatitis. Diagnosing of IgG4-SC is based on typical histopathological images, shape changes revealed by diagnostic imaging, serological tests, concurrent impairment of other organs and response to therapy, where IgG4-SC responds well to treatment with corticoids, whereas the only possibility for the remaining units is endoscopic intervention or liver transplantation. Secondary sclerosing cholangitis may develop as a result of many different insults affecting the biliary tree. Among them, the most frequently described include long-lasting biliary obstruction, surgical injury of the biliary tree, and ischemic cholangitis in liver allotransplants or recurrent pancreatitis. We use serological and imaging examination in PSC diagnostics, sometimes we have to resort to liver biopsy. PSC is to a significant degree accompanied by the presence of idiopathic bowel disease, typically ulcerative colitis. As a result, PSC may lead to cirrhosis of the liver and it is a precancerous condition of several malignancies. With regard to variable locations of the biliary tree injuries concerning the aforementioned units, also certain malignancies in subhepatic landscape need to be considered in the differential diagnosis: pancreatic cancer and cholangiogenous carcinoma.Key words: genetic factors - IBD - IgG4 cholangitis - liver transplantation - bile duct cancer - ursodeoxycholic acid - primary sclerosing cholangitis - secondary cholangitis - sclerosing cholangitis.
