Clinical relevance of colonic bowel wall thickening seen on abdominal CT scans is unknown. Recommendations for further diagnostic procedures are lacking. The aim of this retrospective study was to evaluate detecting of bowel wall thickening on CT scan and findings that were seen in case of endoscopical evaluation.
The radiological database was retrospectively reviewed for all reports of CT scans from 2003 to 2009 at the University Hospital Regensburg, Germany. Patients with underlying diseases for suspected bowel wall thickening were excluded.
Sixty-two patients with bowel wall thickening were detected. Twenty-one percent (13/62) had generalized bowel wall thickening. In 58%, bowel wall thickening was limited to one segment of the colon (36/62), mostly left sided (25/62). Forty-four percent of patients (27/62) were sent to endoscopy. In 15% (4/27), malignancy was suspected, and it could be histologically confirmed in two patients. Nineteen percent (5/27) had normal endoscopy, and 67% (18/62) showed benign findings.
Colonic bowel wall thickening is not a common finding on CT scan in this study. Consequential endoscopic evaluation was performed in less than 50% of patients. Pathological findings were detected in 80% of these patients. We recommend endoscopical evaluation if bowel wall thickening is reported on CT scan.
腹部 CT 扫描显示的结肠肠壁增厚的临床相关性尚不清楚。缺乏进一步诊断程序的建议。本回顾性研究的目的是评估 CT 扫描上肠壁增厚的检测以及内镜评估中发现的结果。
回顾性审查了德国雷根斯堡大学医院 2003 年至 2009 年的所有 CT 扫描报告的放射学数据库。排除了疑似肠壁增厚的基础疾病患者。
共检测到 62 例肠壁增厚患者。21%（13/62）存在广泛性肠壁增厚。58%（36/62）的肠壁增厚局限于结肠的一个节段，大多数位于左侧（25/62）。44%的患者（27/62）接受了内镜检查。在 15%（4/27）的患者中怀疑存在恶性肿瘤，其中 2 例可通过组织学证实。19%（5/27）的内镜检查正常，67%（18/62）显示良性发现。
在本研究中，CT 扫描上结肠肠壁增厚并不常见。在不到 50%的患者中进行了后续的内镜评估。在这些患者中，有 80%的患者发现了病理结果。如果 CT 扫描报告肠壁增厚，我们建议进行内镜评估。
