Purpose: The aim of this study is to clarify the factors linked to bowel necrosis in patients with acute abdomen who had hepatic portal venous gas (HPVG) on computed tomography (CT) scans.
Methods: Over the past 6 years, 22 patients with HPVG detected by CT scan were treated. Medical records from these patients were reviewed to identify signs associated with bowel necrosis. Of the 22 patients with gas in the portal venous system seen on a CT cross-section, nine patients had bowel necrosis. The patients were divided into two groups for comparison: Necrotic bowel group (n=9) and Non-necrotic bowel group (n=13).
Results: Signs of peritoneal irritation were present in all patients of the bowel necrotic group, but in only one of the bowel non-necrotic group (p=0.00002). Age, sex, and laboratory findings were not associated with bowel necrosis. On CT findings, pneumatosis intestinalis (PI) was significantly associated with bowel necrosis (p=0.00732).
Conclusion: Signs of peritoneal irritation and PI were strongly associated with bowel necrosis in acute abdomen patients with HPVG.
