Abstract

Although large bowel obstruction (LBO) is less common than small bowel obstruction, it is associated with high morbidity and mortality due to delayed diagnosis and/or treatment. Plain radiographs are sufficient to diagnose LBO in a majority of patients. However, further evaluation with multidetector computed tomography (MDCT) has become the standard of care to identify the site, severity, and etiology of obstruction. In this comprehensive review, we illustrate the various causes of LBO emphasizing the role of MDCT in the initial diagnosis and detection of complications along with the tips to differentiate from disease which can mimic LBO.
