A study of causes of error on barium enema examinations is reported. There were 144 patients with 189 inflammatory and neoplastic lesions of the large bowel examined endoscopically and with a preceding barium enema. Twelve lesions were not reported radiologically, a false negative error rate of 6.3%. Radiographic errors included 11 polyps and 1 sigmoid carcinoma. Causes for these errors were analyzed and classified into perceptive, technical, or combined categories. Ten lesions were visible in retrospect. Five lesions, clearly visible but not noted, were due to perceptive error. Five other lesions, poorly visible due to faulty studies, represented combined error. Two lesions could not be identified and represented purely technical failure. All unreported lesions were distal to the splenic flexure with the majority located in the sigmoid colon.
本文报告了一项关于钡剂灌肠检查误差原因的研究。对144例患者进行了内镜检查及之前的钡剂灌肠检查，共发现189处大肠炎性和肿瘤性病变。有12处病变在放射学检查中未被报告，假阴性误差率为6.3%。放射学误差包括11处息肉和1处乙状结肠癌。对这些误差的原因进行了分析，并分为感知性、技术性或综合性类别。回顾性分析发现有10处病变是可见的。5处病变清晰可见但未被注意到，属于感知性误差。另外5处病变由于检查不完善而显示不清，属于综合性误差。有2处病变无法识别，属于纯粹的技术失误。所有未报告的病变均位于脾曲远端，大多数位于乙状结肠。
