BACKGROUND
Pyriform sinus fistula is a rare brachial pouch anomaly. However, it is difficult and risky to remove the fistula tract completely. Circumferential chemocauterization of the internal opening with trichloroacetic acid (TCA) for pyriform sinus fistula is simple, reproducible, reliable, and causes less morbidity. The aim of this study was to determine the feasibility of TCA chemocauterization for pyriform sinus fistula.
METHODS
This retrospective study enrolled 44 patients who were diagnosed with pyriform sinus fistula and underwent TCA chemocauterization. We retrospectively reviewed the medical records of the patients to obtain their demography as well as treatment outcomes for them.
RESULTS
The success rate of treatment for pyriform sinus fistula after the first TCA chemocauterization was 77.3% (34/44) and the cumulative success rate after the second treatment was 93.2% (41/44). There was no complication such as vocal fold palsy after TCA chemocauterization.
CONCLUSIONS
It is suggested that TCA chemocauterization can be a reasonable first-line treatment for pyriform sinus fistula.
背景
梨状窝瘘是一种罕见的颈部囊状异常。然而，完全切除瘘管是困难且有风险的。三氯乙酸（TCA）环形化学烧灼梨状窝瘘的内口简单、可重复、可靠，且发病率较低。本研究旨在确定 TCA 化学烧灼治疗梨状窝瘘的可行性。
方法
本回顾性研究纳入了 44 例诊断为梨状窝瘘并接受 TCA 化学烧灼的患者。我们回顾性地查阅了患者的病历，以获取他们的人口统计学资料和治疗结果。
结果
第一次 TCA 化学烧灼治疗后梨状窝瘘的成功率为 77.3%（34/44），第二次治疗后的累积成功率为 93.2%（41/44）。TCA 化学烧灼后无声带麻痹等并发症。
结论
建议 TCA 化学烧灼可作为梨状窝瘘的合理一线治疗方法。
