Detection and Localization of Obscure Lower Gastrointestinal Bleeding by Using SPECT/CT and Intraoperative Endoscopy

目的评价SPECT/CT和术中内镜联合应用在不明原因下消化道出血中的定位诊断作用。方法分析26例不明原因急性下消化道出血住院患者的诊治情况。结果本组26例患者均能术中发现病灶及病因,其中SPECT/CT检查阳性率为88.5%,术中纤维内镜定位准确率为100%,随访1个月至2年无复发。结论不明原因急性下消化道出血患者首选SPECT/CT检查,确定大致部位后,术中再行纤维内镜确切定位,行确定性手术治疗,效果满意。

Objective To evaluate the detection and localization of obscure lower gastrointestinal bleeding by using SPECT/CT and intraoperative endoscopy. Methods Twenty six cases of patients with obscure lower gastrointestinal bleeding were analyzed retrospectively. Results The positive detection rate of SPECT/CT was 88.5%. All 26 patients （100%） were identified the bleeding source by using intraoperative endoscopy. No recurrence was found during 1-24 months follow-up. Conclusion SPECT/CT examination should be chosen firstly for patients with obscure lower gastrointestinal bleeding in order to localize the bleeding site roughly. Intraoperative endoscopy can localize the bleeding site accurately in patients who undergoes operation.
