The aim of this study was to describe the radiographic findings in stercoral colitis.
The computed tomographic scans and abdominal radiographs of 13 patients with surgically and pathologically confirmed stercoral colitis from 4 affiliated hospitals were reviewed by a board-certified abdominal radiologist blinded to the official imaging, surgical, and pathologic findings.
The median age was 66 years. The patients presented mainly with constipation (100%) and an acute inflammatory process (85%); 5 patients (38%) had frank septic shock. Mortality was 46%. Imaging scans showed that the colon dilated proximally to the impaction site in 6 patients (50%). Other findings included fat stranding (100%), mucosal sloughing (58%), mesenteric hyperemia (58%), and extraluminal gas (17%).
Computed tomography is an important diagnostic modality for stercoral colitis. The presence of a large fecaloma with distention of the affected colon and wall thickening and pericolonic fat stranding should alert radiologists and surgeons to the presence of this potentially fatal condition.
本研究旨在描述粪块性结肠炎的影像学表现。
来自4家附属医院的13例经手术及病理证实为粪块性结肠炎的患者的计算机断层扫描和腹部X线片，由一位不了解官方影像、手术及病理结果的腹部放射科专科医师进行回顾分析。
患者的中位年龄为66岁。主要表现为便秘（100%）和急性炎症过程（85%）；5例患者（38%）出现明显的感染性休克。死亡率为46%。影像学扫描显示，6例患者（50%）结肠在粪块阻塞部位近端扩张。其他表现包括脂肪条索征（100%）、黏膜脱落（58%）、肠系膜充血（58%）和肠腔外气体（17%）。
计算机断层扫描是粪块性结肠炎的重要诊断方法。存在大的粪块瘤伴受累结肠扩张、肠壁增厚及结肠周围脂肪条索征，应提醒放射科医师和外科医师注意这种潜在致命疾病的存在。
