Abstract
Seventy-one patients presenting for elective hernia repair without gastrointestinal symptoms were screened for occult blood in their stools. All patients had stools negative for occult blood and were studied with proctosigmoidoscopy and barium enema. Polyps were found in 10% of the study population. The potential for missing polyps definitely exists if patients are selected for further studies only on the basis of tests for occult stool blood.
摘要
对71例择期进行疝修补且无胃肠道症状的患者进行了粪便潜血筛查。所有患者的粪便潜血均为阴性，并接受了直肠乙状结肠镜检查和钡灌肠检查。在研究人群中，10%的患者发现有息肉。如果仅根据粪便潜血检测来选择患者进行进一步研究，肯定存在漏诊息肉的可能性。
