OBJECTIVE: The most common causes of large-bowel obstruction (LBO) are colon carcinoma and volvulus. Nevertheless, the increased frequency of the condition and widespread use of diagnostic imaging have revealed uncommon causes of LBO. We review the imaging features of the unusual causes of LBO on several imaging modalities, with particular emphasis on CT, along with the current literature. CONCLUSION: We propose an algorithmic approach to the radiologic evaluation of the uncommon causes of LBO.
目的：大肠梗阻（LBO）最常见的病因是结肠癌和肠扭转。然而，该疾病发病率的上升以及诊断性成像的广泛应用揭示了LBO的一些罕见病因。我们回顾了几种成像方式下LBO罕见病因的成像特征，尤其着重于CT，并结合当前文献进行阐述。 结论：我们提出了一种针对LBO罕见病因进行放射学评估的算法方法。
