To determine whether computed tomography (CT) can satisfactorily diagnose and evaluate patients with suspected colonic obstruction.
Seventy-five patients with suspected colonic obstruction were evaluated prospectively by CT and compared with the gold standards of surgery and/or endoscopy in 65 patients, clinical course in nine, and contrast enema (CE) in one. A limited comparison between CT and CE (26) patients was also made in those patients who had both studies.
CT successfully diagnosed colonic obstruction in 45 of 47 patients (96% sensitivity). Pseudo-obstruction was correctly diagnosed in 26 of 28 patients (93% specificity). CT correctly localized the point of obstruction in 44 of 47 patients (94%). CE successfully diagnosed obstruction in only 20 of 25 patients (80% sensitivity).
In this study, CT proved to be a satisfactory modality in evaluating patients with suspected colonic obstruction. CT may in certain circumstances be preferable to the traditional CE in evaluating these patients.
确定计算机断层扫描（CT）能否令人满意地诊断和评估疑似结肠梗阻患者。
对75例疑似结肠梗阻患者进行前瞻性CT评估，并与65例患者的手术和/或内镜检查金标准、9例患者的临床病程以及1例患者的结肠造影（CE）结果进行比较。对同时进行了CT和CE检查的26例患者，还对两者进行了有限的比较。
CT在47例患者中的45例成功诊断出结肠梗阻（敏感性96%）。在28例患者中的26例正确诊断出假性梗阻（特异性93%）。CT在47例患者中的44例正确定位了梗阻点（94%）。CE仅在25例患者中的20例成功诊断出梗阻（敏感性80%）。
在本研究中，CT被证明是评估疑似结肠梗阻患者的一种令人满意的方式。在评估这些患者时，CT在某些情况下可能比传统的CE更可取。
