先天性气管食管瘘(简称 TE 瘘)根据其解剖上的特点,分为五种类型:(1) 食管闭锁无TE 瘘,(2) 食管闭锁合并上端 TE 瘘,(3) 食管闭锁合并下端 TE 瘘,(4) 食管闭锁合并上、下两端 TE 瘘,(5) 无食管闭锁 TE 瘘即“H”型。所有的先天性气管食管瘘畸形病例中,85～95%属于食管闭锁合并下端 TE 瘘,“H”型 TE瘘的发病率仅占先天性气管食管畸形中1(1/2) ～
Congenital tracheal esophageal fistula (referred to as TE fistula) according to their anatomical characteristics, divided into five types: (1) esophageal atresia without TE fistula, (2) esophageal atresia combined with the upper TE fistula, (3) esophageal atresia combined with the lower TE Fistula, (4) Esophageal atresia combined with TE fistula at both upper and lower ends, and (5) TE fistula with “Esophageal atresia” type “H”. All cases of congenital tracheoesophageal fistula deformity, 85-95% belong to esophageal atresia combined with the lower TE fistula, “H” type TE fistula incidence of congenital tracheoesophageal malformations only 1 (1/2) ~
