A changing understanding in the presentation of patients with hepatoportal venous gas: a case report.

Often believed to be a poor prognostic sign, hepatoportal venous gas (HPVG) has been associated with massive intra-abdominal sepsis. It is more frequently detected as computed tomography imaging techniques improve. A patient presenting with radiological evidence of HPVG is discussed and the literature reviewed. This study aims to highlight the increasing understanding that HPVG may sometimes follow a more indolent course than previously believed. Patient assessment is the key in selecting those who need urgent laparotomy.
