儿童非囊肿型先天性梨状窝瘘的诊断及内镜微创治疗效果OACSTPCD

Objective To explore the effect of the diagnosis and endoscopic minimally invasive surgical treatment of non-cystic congenital pyriform sinus fistula(CPSF)in children.Methods Clinical data of 76 children with non-cystic CPSF were retrospectively analyzed from October 2017 to May 2022.Larygoscope,neck color ultrasound,esophageal barium meal,neck CT,and magnetic resonance imaging(MRI)were performed,and temperature-controlled ablation radio-frequency was performed under general anesthesia supported by laryngoscope guidance.Results The internal fistula in the pyriform fossa was seen under laryngoscope.Imaging examination shows that the fistula was connected to the pharynx.Postoperative complications:hoarseness in 3 cases and deciduous tooth loss in 3 cases.After a follow-up period of 12～40 months,there was 1 recurrence in 46 newly treated patients and 1 recurrence in 30 non newly treated patients.No recurrence was observed during the follow-up period after re-endoscopic radiofrequency plasma surgical electrodes plasma cauterization.Conclusion The symptoms of CPSF are non-specific.The discovery of the internal fistula under endoscopy is the gold standard for diagnosis.Ultrasound can be used as the initial screening method for diagnosis.Esophageal barium meal combined with CT examination can improve the diagnostic rate,and MRI can assist in diagnosis.The temperature-controlled ablation radio-frequency technique under supportive laryngoscope has the advantages of safety,minimally invasive,aesthetic,convenient,and repeatable operation,and can be used as the preferred method for the treatment of non-cystic CPSF in children.
