ABSTRACT

OBJECTIVE: to evaluate the impact of the new technology of multidetector computed tomography (MDCT) in improving the accuracy and early diagnosis of BSBI. METHODS: patients with blunt small bowel injuries (BSBI) grade> I were identified retrospectively and their CT scans reviewed by an experienced radiologist. Clinical and tomographic findings were analyzed and patients grouped as "pre-MDCT" and "post-MDCT", according to the time of implementation of a 64-slice MDCT. RESULTS: of the 26 patients with BSBI 16 had CT scans. Motor vehicle collision (62.5%) was the most frequent mechanism of injury. In the pre-MDCT period, five of the 13 patients (38.5%) had abdominal CT, and in the post-MDCT, 11 of 13 patients (84.6%) had the exam. During pre-MDCT, all CT scans were abnormal with findings of pneumoperitoneum (60%), free fluid (40%) and bowel wall enhancement (20%). In the post-MDCT group, all exams but one were abnormal and the most frequent findings were free fluid (90.9%), bowel wall enhancement (72.7%), and pneumoperitoneum (54.5%). However, the rate of delayed laparotomy did not change. The mortality rate in both groups were similar, with 20% during pre-MDCT and 18.2% during post-MDCT. CONCLUSION: the use of MDCT in abdominal trauma in our service has increased the sensibility of the diagnosis, but has had no impact on outcome so far. .


OBJETIVO: avaliar se o avanço tecnológico dos aparelhos de tomografia computadorizada (TC) melhorou a acurácia e rapidez no diagnóstico dessas lesões. MÉTODOS: pacientes com lesão de intestino delgado grau>I (AAST-OIS) por trauma contuso foram identificados e suas imagens de TC analisadas por especialista. Foram analisados achados clínicos e tomográficos agrupando os pacientes em antes e após o uso da TC multislice 64 canais, incorporada em nosso Serviço em abril de 2009. RESULTADOS: Dentre os 26 pacientes identificados entre 2005 e 2012, 16 realizaram TC. Acidente automobilístico (62,5%) foi o principal mecanismo de trauma. No período pré-multislice, cinco dentre 13 pacientes (38,5%) realizaram TC e no pós-multislice 11 de 13 (84,6%). No grupo pré-multislice todos os exames foram alterados, sendo os principais achados pneumoperitônio (60%), liquido livre (40%) e espessamento da parede intestinal (20%). No grupo pós-multislice apenas um exame foi considerado normal e os achados mais frequentes nos outros 10 casos foram: líquido livre (90,9%), espessamento da gordura do mesentério (72,7%) e pneumoperitônio (54,5%). Não foi observada mudança no intervalo de tempo entre a realização de TC e a laparotomia. A mortalidade em ambos os grupos foi semelhante (20% no pré-multislice e 18,2% no pós-multislice). CONCLUSÃO: O uso de tomografia multislice aumentou a sensibilidade do diagnóstico, porém sem alteração na evolução dos pacientes. .
