Core Tip

Core tip: A rare case of hepatic portal venous gas (HPVG) is reported. Endoscopy through ileostomy leaded the formation of HPVG induced by obstructive colitis. The anastomosis of rectum was totally obstructed after rectum cancer operation. For nine months, the mucosa of ascending to sigmoid colon has changed atrophy for disuse. The patient’s condition improved after emergent operation of transverse colostomy. In patients with anastomotic obstruction or severe stenosis, colonoscopy through diverting stoma should be avoided.
