A case of hepatic portal venous gas after colonoscopy.

Hepatic portal venous gas (HPVG) is a rare radiologic finding that is usually precipitated by intestinal ischaemia, intra-abdominal abscesses, necrotising enterocolitis, abdominal trauma, infectious enteritis, and inflammatory bowel disease. In this study, we present a case of HPVG in a 66-year-old female patient who underwent colonoscopy for evaluation of haematochezia and a review of the literature focused on HPVG following colonoscopy.
