| 3 | Hepatic portal venous gas after endoscopy in a patient with anastomotic obstruction显示文摘A 72-year-old male underwent a laparoscopic low anterior resection for advanced rectal cancer.A diverting loop ileostomy was constructed due to an anastomotic leak five days postoperatively.Nine months later,colonoscopy performed through the stoma showed complete anastomotic obstruction.The mucosa of the proximal sigmoid colon was atrophic and whitish.Ten days after the colonoscopy,the patient presented in shock with abdominal pain.Abdominal computed tomography scan showed hepatic portal venous gas(HPVG) and a dilated left colon.HPVG induced by obstructive colitis was diagnosed and a transverse colostomy performed emergently.His subsequent hospital course was unremarkable.Rectal anastomosis with diverting ileostomy is often performed in patients with low rectal cancers.In patients with anastomotic obstruction or severe stenosis,colonoscopy through diverting stoma should be avoided.Emergent operation to decompress the obstructed proximal colon is necessary in patients with a blind intestinal loop accompanied by HPVG. | Ai Sadatomo Koji Koinuma Rihito Kanamaru Yasuyuki Miyakura Hisanaga Horie Alan T Lefor Yoshikazu Yasuda | 2015 | World Journal of Gastrointestinal Surgery2015，7，2： | 2 |
