食管狭窄(Stenosis of the esophagus)可分先天性与后天性两种,在狭窄部位的上方伴有食管扩张和肥厚。先天性食管狭窄(CES)是指出生后就已经存在的因为食管壁结构内在狭窄而导致的畸形。主要表现是在进餐后会出现食物反流,而摄取半固体或固体食物时表现会更加明显。反流物里主要是唾液和消化不良的乳汁或食物,并没有酸味也不含有胆汁。
Stenosis of the esophagus can be divided into two types of congenital and acquired, at the top of the stenosis with esophageal dilation and hypertrophy. Congenital Esophageal Stenosis (CES) refers to the deformity that occurs after birth due to the stenosis of the esophageal wall structure. The main manifestation is that food reflux occurs after a meal, and the performance when taking semi-solid or solid food will be more obvious. Reflux material is mainly saliva and indigestion of milk or food, and no sour and does not contain bile.
