ABSTRACT
SUMMARY

OBJECTIVE:

To assess the diagnostic performance of CT findings in differentiating causes of pneumatosis intestinalis (PI), including benign and life-threatening causes.

METHODS:

All CT reports containing the word "pneumatosis" were queried from June 1st, 2006 to May 31st, 2015. A total of 42 patients with PI were enrolled (mean age, 63.4 years; 23 males and 19 females) and divided into two groups on based on electronic medical records a benign group (n=24) and a life-threatening group (n=18). Two radiologists reviewed CT images and evaluated CT findings including bowel distension, the pattern of bowel wall enhancement, bowel wall defect, portal venous gas (PVG), mesenteric venous gas (MVG), extraluminal free air, and ascites.

RESULTS:

CT findings including bowel distension, decreased bowel wall enhancement, PVG, and ascites were more commonly identified in the life-threatening group (all p<0.05). All cases with PVG were included in the life-threatening group (8/18 patients, 44.4%). Bowel wall defect, extraluminal free air, and mesenteric venous gas showed no statistical significance between both groups.

CONCLUSION:

PI and concurrent PVG, bowel distension, decreased bowel wall enhancement, or ascites were significantly associated with life-threatening causes and unfavorable prognosis. Thus, evaluating ancillary CT features when we encountered PI would help us characterize the causes of PI and determine the appropriate treatment option.
RESUMO
RESUMO

OBJETIVO:

Avaliar o desempenho diagnóstico dos achados CT em causas diferenciadoras da pneumatose intestinal (PI), incluindo causas benignas e que ameaçam a vida.

MÉTODOS:

Todos os relatórios CT contendo a palavra "pneumatose" foram questionados de 10 de junho de 2006 a 31 de maio de 2015. Um total de 42 pacientes com PI foi matriculado (idade média 63,4 anos, 23 do sexo masculino e 19 do sexo feminino) e divididos em dois grupos na base de registros médicos elétricos grupo benigno, n = 24 e grupo com risco de vida, n = 18. Dois radiologistas analisaram as imagens da CT e avaliaram seus achados, incluindo distensão intestinal, padrão de realce da parede intestinal, defeito da parede intestinal, gás venoso portal (PVG), gás venoso mesentérico (MVG), ar extraluminal e ascite.

RESULTADOS:

Achados CT, incluindo distensão intestinal, diminuição do realce da parede intestinal. PVG e ascite foram mais comumente identificados em grupo com risco de vida (todos p < 0,05, respectivamente). Todos os casos com PVG foram incluídos em grupo com risco de vida (8/18 pacientes, 44,4%). Defeito da parede do intestino, ar livre extraluminal e gás venoso mesentérico não mostraram significância estatística entre dois grupos.

CONCLUSÃO:

PI e PVG concorrente, distensão intestinal, diminuição do aumento da parede do intestino ou ascites foram significativamente associados com causas que ameaçaram a vida e prognóstico desfavorável. Portanto, avaliar os recursos de CT auxiliares quando encontramos PI nos ajudaria a caracterizar as causas de PI e determinar a opção de tratamento apropriada.
