Argon plasma coagulation for endoscopic treatment for congenital pyriform sinus fistula in children.

OBJECTIVE

This study aimed to evaluate the efficacy of a novel endoscopic approach using argon plasma coagulation (APC) for the treatment of congenital pyriform sinus fistulas (CPSF) in children.

METHODS

A retrospective analysis was conducted on 30 pediatric patients with PSF who were treated at Fujian Children's Hospital (Fujian Branch of Shanghai Children's Medical Center) between 2021 and 2025. All patients underwent neck color Doppler ultrasound and electronic laryngoscopy, with systematically analyzed of the results. Postoperative follow-up was performed at multiple time points.

RESULTS

All 30 procedures were successfully completed, with no cases of pharyngeal fistula, dysphagia, or infection around or beyond the fistula tract. During the follow-up period, ranging from 2 weeks to 3 years, no recurrence was observed.

CONCLUSION

Endoscopy-assisted argon plasma coagulation is a promising treatment for CPSF in children, offering advantages including minimal trauma, reduced bleeding, and clear visualization. This method appears safe and effective for infants and children with CPSF and warrants wider clinical adoption.
