[Advances in endoscopic treatment of congenital pyriform sinus fistula in children]

Pyriform sinus fistula is a rare clinical disease, often with recurrent acute suppurative thyroiditis or neck infection in children.The traditional method treatment is complete resection of the fistula with or without hemithyroidectomy in external cervical surgical approach, but in recent years, minimally invasive endoscopic occlusion of the internal opening for the treatment of pyriform sinus fistula is performed in many hospitals, including electrocautery, chemocautery, laser cauterization, biocauterization, and suture closure. Literatures about endoscopic management of pyriform sinus fistula in children are reviewed and various surgical methods, complications and success rate are evaluated.梨状窝瘘是一种临床上罕见的疾病，常表现为反复急性化脓性甲状腺炎或颈部感染。过去传统的手术方法是颈外径路完整切除瘘管，伴或者不伴有患侧甲状腺切除，但近年来许多医院开展微创内镜下闭塞内瘘口方法来治疗梨状窝瘘，其中包括电烧灼、化学烧灼、激光烧灼、生物胶治疗、缝合技术等。因此，本文收集国内外内镜下治疗儿童梨状窝瘘的相关文献，并综述各类手术方法、并发症及治疗有效率。.
