Evaluation of patients with hepatic portal venous gas who can be treated with conservative therapy

Aim: Hepatic portal venous gas is an indication for emergency surgery and reportedly has a high mortality rate. However, these days, cases of hepatic portal venous gas associated with milder disease are increasing. In this report, we compared two groups to investigate whether there were any objective indicators for selecting conservative therapy. Methods: From July 2007 to August 2011, 19 patients with hepatic portal venous gas were evaluated at our hospital. The condition was diagnosed by computed tomography imaging. Vital signs, laboratory test results, and physical examination findings were compared. Results: The A group included 12 patients who could be treated with conservative therapy. The B group included 7 patients who could not be treated with conservative therapy. The combined mortality rate was 31.5% (6/19 patients). There was a significant difference in the pulse rate and shock index. In the A group, none of the patients had signs of peritoneal irritation. However, in the B group, physical examination revealed signs of peritoneal irritation in all patients. Conclusion: Conservative therapy may be possible in patients with hepatic portal venous gas, depending on the cause. Evaluation of vital signs and serial changes on physical examination are important.
