胃-食管反流常在临床引起明显症状如烧心、反酸、反食,更可引起胸骨后疼痛、咽下不适等,且可造成食管下段糜烂、溃疡,愈合成可有异型增生(Barrett 食管)等病变。因此,检查并诊断胃-食管反流、深入了解其发病机制具有重要意义。我们用放射性核素方法对此做了初步探索。 Stomach - esophageal reflux often cause clinically significant symptoms such as heartburn, acid reflux, anti-food, but also can cause post-sternal pain, swallowing and discomfort, etc., and can cause erosion of the lower esophagus, ulcers, healing can have dysplasia (Barrett’s esophagus ) And other diseases. Therefore, to check and diagnose gastric-esophageal reflux, to understand its pathogenesis is of great significance. We used radionuclide method to do this preliminary exploration.
