反流性食管炎是由于食管下端括约肌不能阻止胃十二指肠分泌物的反流,因反流物刺激而引起食管粘膜的损害。近些年来,由于对胃肠道激素、受体学说的深入研究及电影萤光摄片、纤维食管镜检、食管拉网细胞学检查、食管压力计的临床应用等项技术的发展、对食管功能的研究及食管疾病的诊断、取得了重大的进展。从而对本病已可作出较准确的诊断和提供较合 Reflux esophagitis is due to the lower esophageal sphincter can not prevent reflux of gastroduodenal secretions, esophageal mucosa damage caused by reflux. In recent years, due to gastrointestinal hormones, receptor theory and in-depth study of the film fluorescence imaging, esophageal fiberoscopy, esophageal cytology, esophageal pressure gauge clinical application of other technologies, the esophagus Functional research and diagnosis of esophageal diseases, made significant progress. Thus the disease has been able to make a more accurate diagnosis and provide a better match
