Metastatic colon cancer from extrahepatic cholangiocarcinoma presenting as painless jaundice: case report and literature review.

Cholangiocarcinoma (CCA) is a rare cancer of the biliary epithelium comprising only about 3% of all gastrointestinal malignancies. It is a highly aggressive malignancy and confers a dismal prognosis with majority of patients presenting with metastatic disease. Metastatic CCA to the colon is extremely rare with only few cases reported in the literature.

A multicenter analysis of safety and outcome of removal of a fully covered self-expandable metal stent during ERCP.

Background: Fully covered self-expandable metal stents (FCSEMSs) have been used for palliation of both malignant and benign biliary strictures. Limited data are available about safety and outcome of endoscopic removal of these stents.

Objective: To evaluate safety and efficacy of endoscopic removal of FCSEMSs.

A pilot study of urokinase-type plasminogen activator (uPA) overexpression in the brush cytology of patients with malignant pancreatic or biliary strictures.

We have previously demonstrated that uPA is overexpressed in pancreatic tumors. In an attempt to diagnose these tumors earlier, we sought to determine whether uPA could be identified in endoscopic retrograde cholangiopancreatography obtained brushings in patients with malignant pancreatic and biliary strictures. Secondarily, uPA was measured in the serum of this patient population.
