【Abstract】　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.
