放射性核素胃食管显象测定胃食管返流

The eletermiation of GER using gastroes-ophageal image in technique.

放射性核素胃食管显象诊断胃食管返流具有方法简便、灵敏、非侵入性、定量等优点。作者用本法检测18例正常人均未见返流,84例胃食管返流可疑病人检出率为78.6％,而X线钡剂胃肠和内窥镜检查的检出率仅为70.2％和26％,分别为放射性核素显象检出率的89.3％和33.1％。

The Diagnosis of gastroesophageal reflux (GER) using radionuclide imaging is a simple, sensitive non-invasive and guantitative technique. This paper reported the results of 18 normal persons and 84 cases of suspected GER patients examined by this technique. No reflux was found in normal group, there were 78.6% detectability in paients group, while the detectability X-ray examination were 70.2% in same group of patients. 23 cases were undergoing endoscopic examination, only 6 cases had revealed the presence of reflux, thereby elete-ctability was only 26.0%.
