Conservative treatment of hepatic portal venous gas consecutive to a complicated diverticulitis: A case report and literature review

• A Conservative treatment of hepatic portal venous gas is described.
• The literature showed only one clinical trial establishing a scoring system.
• A pneumoportogram (hepatic portal venous gas) is a very rare and from poor prognosis.

Introduction and presentation of caseEight days after being diagnosed with multiple small strokes a 71 year old male patient is readmitted with suspicion of a petit mal seizure also complained of diarrhoea and abdominal pain. The patient was stable, not febrile and neurologically intact with a slight tenderness in the left lower quadrant. An ultrasound revealed presence of air in the hepatic portal venous system and a suspicion for sigmoid diverticulitis. A CT-scan confirmed both diagnoses. We proceeded with a conservative regimen under close observation. The clinical course and laboratory results were unremarkable.DiscussionThe review of the literature (PubMed database) triggered 685 items with only one clinical trial establishing a scoring system to detect adult individuals, which need operation.ConclusionA pneumoportogram (hepatic portal venous gas, HPVG) is a very rare and usually associated with bowel ischemia and from poor prognosis. The last decades saw the emergence of numerous other aetiologies (also benign) with a shift of paradigm from systematic emergency laparotomies to individual patient selection.
