Abstract
Hepatic portal venous gas is an ominous prognostic sign. We report a case of survival of necrotizing enteritis with hepatic portal venous gas and pneumatosis cystoides intestinalis. A 71-year-old man was admitted with a sudden onset of severe abdominal pain and vomiting. Hepatic portal venous gas wasdetected by conventional radiography, ultrasonography, and computed tomography. In an emergency laparotomy, the necrotic bowel was resected, and the patient survived. Hepatic portal venous gas suggests the presence of necrotic bowel, so it usually indicates the need for urgent surgical intervention. Since hepatic portal venous gas is difficult to detect by conventional radiography, computed tomography is a more valuable method for this purpose.
