Management of malignant biliary diseases by the use of peroral and percutaneous cholangioscopy.

Background And Aims: The single-operator digital cholangioscope has allowed visual access to the biliary tree and the ability to perform selective biopsies. This has significantly improved our diagnostic yield in bile-duct disorders. Cholangioscopy requires specialized equipment and expertise.

Gastric Perforation Following Prophylactic Embolization of Right Gastric and Gastroduodenal Arteries Prior to Selective Internal Radiation Therapy.

Prophylactic gastroduodenal artery (GDA) and right gastric artery (RGA) embolization for prevention of gastric ulceration in patients with hepatic metastases from colorectal cancer undergoing Selective Internal Radiation Therapy (SIRT) are relatively safe. Herein, we present a case of gastric perforation following prophylactic embolization of the GDA and RGA for SIRT in a 43-year-old male with sigmoid colon adenocarcinoma and multiple hepatic metastases.

Giant colonic diverticulum.

Background: Over 100 giant colonic diverticuli have been recorded in the literature to date. The magnetic resonance imaging (MRI) and pathophysiology of their aetiology have rarely been described.

Aim: To report a giant colonic diverticulum along with the MRI of this clinical entity.
