为评价~(99m)Tc-RBC显像检查对消化道出血的诊断价值,我们对41例消化道出血进行检查,部分病例与内镜、动脉造影比较.结果:41例核素显像阳性率为73.2%,其中上消化道出血占52.9%,下消化道出血为87.5%.6例行胃镜检查的核素显像阳性的上消化道出血病例中,核素显像定位诊断符合率为66.7%.在下消化道出血核素显像阳性率明显高于动脉造影与结肠镜检.其中7例行手术病检的病例,定位诊断符合率达85.7%.结果提示,核素显像检查灵敏、可靠、耐受性好,对上消化道出血可作为胃镜的补充;对下消化道出血有更高的定位诊断符合率,可为外科手术提供可靠信息.
In order to evaluate the value of 99m Tc-RBC imaging in the diagnosis of gastrointestinal bleeding, 41 cases of gastrointestinal bleeding were examined, and some cases were compared with endoscopic and arterial angiography.Results: The positive rate of 41 cases of radionuclide imaging Was 73.2%, in which upper gastrointestinal bleeding accounted for 52.9%, lower gastrointestinal bleeding was 87.5% .6 cases of gastroscopy in radionuclide-positive cases of upper gastrointestinal bleeding, radionuclide imaging diagnosis was 66.7 % In the lower gastrointestinal hemorrhage nuclide imaging was significantly higher than the rate of angiography and colonoscopy.Among them, 7 cases of surgical disease cases, the diagnostic accuracy rate of 85.7% .The results suggest that nuclide imaging examination is sensitive, Reliable and well-tolerated, the upper gastrointestinal bleeding can be used as a gastroscopy supplement; lower gastrointestinal bleeding with a higher diagnostic accuracy of positioning can provide reliable information for surgery.
