先天性食管病,如食管隔膜、下食管蹼环、食管闭锁、食管过短、食管组织异位等已为临床所了解,但也有些疾病至今尚未完全清楚。近年来,测压、pH监测、核素扫描、内镜检查、超声内镜等的发展,为一些疾病提供了良好的诊疗手段。当前对食管疾病的研究重点是运动功能障碍性疾病和胃食管反流病。本文仅就食管运动功能异常的疾病—食管贲门失弛缓症加以讨论。 Congenital esophageal disease, such as the esophageal membrane, the lower esophageal ring, esophageal atresia, esophageal ectopic esophageal ectopic has been clinically understood, but some diseases have not yet fully understood. In recent years, the development of manometry, pH monitoring, radionuclide scanning, endoscopy, endoscopic ultrasound and so on has provided a good means of diagnosis and treatment for some diseases. Current research on esophageal diseases focuses on motor dysfunction and gastroesophageal reflux disease. This article only on esophageal motility disorders - esophageal achalasia to be discussed.
