Ursodeoxycholic acid (UDCA) is the first-line treatment for primary biliary cirrhosis (PBC). The long-term administration of UDCA might indirectly favor colon carcinogenesis by increasing the fecal excretion of secondary bile acids or, in contrast, it might inhibit colon carcinogenesis, as demonstrated in animal models. In patients with PBC, we examined ...

Most patients with colonoscopy-induced colonic perforation require urgent surgical intervention. Certain patients may, however, recover with conservative management. If the colonic perforation has been induced by barotrauma, there may be an extravasation of air which may lead to collection and tracking of air along the tissue planes, involving the retroperitoneum, ...
