Abstract
We report two cases of hepatic portal venous gas without bowel necrosis. Case 1: A 79-year-old woman hospitalized for cerebral infarction developed enterocolitis symptoms of the intestine luxus. Case 2: A 48-year-old woman developed paralytic ileus symptoms due to neuroleptic internal use. In a review of 106 cases of portal venous gas without bowel necrosis reported from 1986 to 2008 in Japan, overall mortality was 4.7% and underlying diseases were inflammatory bowel disease (45.3%), gastrointestinal trace (GIT) obstruction and dilation (29.2%), sepsis (9.4%), iatrogenic injury and trauma (4.7%), cancer (3.8%), and miscellaneous (7.5%). Surgery was done in 51.4%. Positive PCI was 26.6%. Given the many causes of portal-vein gas without bowel necrosis, determining a treatment policy requires careful physical examination and accurate diagnostic imaging.
