[Hepatic portal venous gas].
OBJECTIVE
Hepatic portal venous gas is a radiological symptom associated with a poor prognosis (75% to 90% mortality). The aim of this retrospective study was to report 7 cases observed over a 2-year period.


METHODS
From June 1997 to November 1999, hepatic portal venous gas was diagnosed in 6 patients by CT scan and in one patient by echosonography. It was not detected in any case by plain abdominal X-rays. Three patients had small bowel obstruction with necrosis, three had extensive superior mesenteric infarction and one had preperforative necrosis of the colon.


RESULTS
One patient with extensive intestinal infarction and a metastatic head and neck cancer was not operated. Two patients were operated, but the extensive mesenteric infarction was not amenable to surgical management. Three of the 7 patients died, while the other four patients survived after resection of the necrotic small intestine (n = 3) and left colectomy extended to the transverse colon (n = 1).


CONCLUSIONS
Hepatic portal venous gas was associated with intestinal necrosis in the seven cases of this series. The severity of portal venous gas is only correlated with the severity of the disease causing portal venous gas.
