Portal venous gas has traditionally been considered an indicator of a poor prognosis due to @entity39 . Portal venous gas has recently been detected in @entity1 with various clinical conditions, such as @entity30 , chemotherapy, and blunt @entity3511 without @entity39 . We herein report the first case of a @entity1 with @entity5 in whom portal venous gas developed after low anterior resection without @entity834 or @entity39 . A 66-year-old @entity1 who had undergone low anterior resection started having severe @entity294 the day after the operation. A fever was present for 2 days after the operation but resolved on postoperative day 3. The @entity1 complained of @entity490 5 days postoperatively. Computed tomography showed portal venous gas. Emergency open laparotomy was performed, but only limited ascites fluid without leakage or @entity39 was found. We irrigated the abdominal cavity and performed an ileostomy with insertion of a drainage tube in the rectovesical pouch. Only serous ascites was discharged through the drainage tube. The portal venous gas disappeared 3 days after the second operation. The @entity1 was discharged in good condition 21 days after the first operation. Portal venous gas can develop after rectal surgery without @entity834 or @entity39 . Conservative treatment is reasonable for @entity1 without signs of @entity39 or panperitonitis. However, @entity1 with portal venous gas must be carefully observed because portal venous gas may be life threatening.
