摘要先天性梨状窝瘘(congenital pyriform sinus fistula,CPSF)为罕见的颈部鳃源性疾病,主要表现为急性化脓性甲状腺炎、反复发作的颈部脓肿和蜂窝织炎.既往认为炎症静止期,手术切除瘘管是唯一根治手段.但传统开放性手术并发症较多,复发率较高.上世纪90年代末,各种相对安全有效、微创美观的内镜术式被尝试应用于先天性梨状窝瘘的治疗.经过10余年的临床验证,内镜烧灼逐渐被推荐为先天性梨状窝瘘的首选治疗方法.该文介绍和总结内镜技术治疗先天性梨状窝瘘的原理、方法、利弊、手术适应证、并发症及预防.

abstractsCongenital pyriform sinus fistula (CPSF) is a rare branchial abnormality,presented as acute suppurative thyroiditis, recurrent neck abscess and cellulitis.In the past, the only way to cure CPSF is surgical resect of the whole lesion in the inflammation quiescent period, which always lead to many complications and high rate of recurrence.Since late 1990s,different kinds of endoscopic procedures have beeen attempted to close the inner orifice of congenital pyriform sinus fistula.After more than 10 years,endoscopic cauterization has been recommended as the first-line treatment for its safety, effective and minimally invasive.This paper introduces and summarizes the theory, procedure, advantages and disadvantages, indications and complications of endoscopic treatment of congenital pyriform sinus fistula.
