The aim of this study was to evaluate computed tomography enteroclysis (CTE) of the small intestinal tract.
A total of 36 patients underwent CTE for further examination of small intestinal disease.
The indications were obscure gastrointestinal bleeding (OGIB) (n = 16), suspected Crohn's disease (n = 7), suspected and diagnosed by exclusion a small intestinal tumor (n = 5), and others (n = 8). Regarding OGIB, positive findings were observed in nine patients: angiodysplasia (n = 2), suspected ileac tumor (n = 2), colon cancer (n = 1), colon diverticulosis and diverticulitis (n = 2), Crohn's disease (n = 1), and enteritis (n = 1). As for Crohn's disease, hyperplasia of the small intestinal wall was shown in six patents. Positive findings of a small intestinal tumor were observed in two patients. In the "others" category, colon diverticulitis was found in three patients and isolated dissection of the superior mesenteric artery in one of four patients with abdominal pain. Primary carcinoid was identified in the pancreas in one patient, with liver carcinoid metastasis in the remaining four patients.
CT enteroclysis is a noninvasive method and useful approach in the diagnosis of small intestinal diseases.
本研究旨在评估小肠计算机断层肠摄影术（CTE）。
共有 36 名患者因小肠疾病进一步检查而行 CTE。
适应证为不明原因胃肠道出血（OGIB）（n=16）、疑似克罗恩病（n=7）、疑似小肠肿瘤并经排除诊断（n=5）及其他（n=8）。对于 OGIB，9 例患者有阳性发现：血管发育不良（n=2）、疑似回肠肿瘤（n=2）、结肠癌（n=1）、结肠憩室炎和憩室炎（n=2）、克罗恩病（n=1）和肠炎（n=1）。对于克罗恩病，6 例患者显示小肠壁增生。2 例患者有小肠肿瘤的阳性发现。在“其他”类别中，3 例患者有结肠憩室炎，4 例腹痛患者中有 1 例肠系膜上动脉孤立夹层。1 例患者胰腺原发性类癌，4 例患者肝脏类癌转移。
CT 肠摄影术是一种非侵入性方法，对小肠疾病的诊断具有重要意义。
