A CASE OF STENOSIS OF ISCHEMIC ASCENDING COLON WITH PORTAL VENOUS GAS TREATED WITH LAPAROSCOPY-ASSISTED SURGERY

Abstract

A 76-year-old woman was transported to our hospital emergency room for right flank pain with hematochezia. Abdominal CT examination revealed portal venous gas in the left lobe of the liver and wall thickness of the ascending and transverse colon. General condition of the patient was stable. A follow-up CT, 2 days later, showed portal venous gas was decreasing. Because of the persistent localized abdominal pain, we performed colonoscopy 3 weeks later and severe stenosis was detected in the ascending colon and cecum. We performed laparoscopy-assisted right hemi-colectomy and the histopathological study revealed ischemic changes at the stenotic lesion.
