Abstract

Purpose

Pneumatosis intestinalis (PI) is increasingly being detected in recent years with the more frequent use of computerized tomography (CT). The present study was performed to evaluate the clinico-radiologic characteristic presentation of PI and to determine the prognostic factors for mortality.

Methods

Fifteen patients who were diagnosed with PI on CT between June 2000 and May 2010 were retrospectively reviewed. Age, sex, location of PI, presence of portal vein gas, time to diagnosis, American Society of Anesthesiologists (ASA) classification, Acute Physiology And Chronic Health Evaluation II (APACHE II), acidosis, shock, and other associated findings were analyzed for their association with outcome.

Results

Fifteen patients (7 males and 8 females, average age, 60.3 years) were diagnosed with PI. Mortality rate was 47% (7 patients). The mortality rate in patients with septic shock, APACHE II score (18), acidosis (pH<7.36) were all 100%, 87%, 100%, respectively (P<0.05). Age, sex, location of PI, portal vein gas, time to diagnosis, ASA classification, associated findings did not show statistical difference.

Conclusion

Shock, APACHE II score (18) and acidosis were associated with high mortality in patients with PI. So, more intensive management and interest are recommended in patients with shock, APACHE II score (18), and acidosis due to PI.
