Purpose: The accuracy of CT in the detection of injuries of the solid visceral organs is well established, butthe value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conductedto ascertain CT finding of small bowel rupture result from abdominal trauma. Materials and Methods: Aretrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture wasconfirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. Results:Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of thebowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal orretroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collectionwas seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases,respectively. Conclusion: The CT scan is sensitive and effective modality for evaluation of small bowel ruptureafter abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.
