RESUMO
ABSTRACT Objective There is currently no consensus regarding the optimal management of acute suppurative thyroiditis (AST) secondary to pyriform sinus fistula (PSF). To investigate the benefits and adverse events of aspiration with or without lavage for the treatment of AST secondary to PSF. Subjects and methods This was a retrospective analysis of consecutive patients with AST secondary to PSF who were admitted at the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University between August 2012 and December 2018. Clinical information, procedural data, and imaging data were analyzed. Results Seven patients (five women; mean age, 16.9 ± 6.3 years; range, 8-26 years) were included. The patients most presented with anterior neck pain and swelling (n = 7), fever (n = 7), or odynophagia (n = 5). Six cases of AST occurred on the left side of the thyroid and 1 on the right. All patients had thyroid abscess. AST was diagnosed by ultrasound-guided needle aspiration cytology in all cases. PSF was diagnosed during the inflammatory stage in five patients and during the quiescent stage in two. All patients were treated with empiric antibiotics. Needle aspiration without lavage was performed in three cases. Needle aspiration with lavage was performed in four cases. Repeat aspiration was performed in three cases. All patients recovered completely, with no procedure-related complications. During 18.3 ± 7.8 months of follow-up, AST recurred in one case. Excision of the PSF was performed in another case. Conclusion Ultrasound-guided aspiration with or without lavage had a good treatment effect and without adverse events for the management of AST secondary to PSF.

Resumen Introducción: Las fístulas del seno piriforme, originadas desde el tercer o cuarto arco branquial, son entidades poco frecuentes. Se pueden presentar como aumento de volumen cervical, fístula cervical, absceso cervical, tiroiditis abscedada y/o disfonía. Objetivo: Reportar 4 casos tratados en nuestro hospital y revisión de la literatura. Discusión: Frente a un cuadro clínico compatible, se debe realizar estudio endos- cópico y de imágenes. El manejo quirúrgico sigue siendo el de mejores resultados, pero se han desarrollado terapias endoscópicas y combinaciones de estas con buenos resultados. Conclusión: El diagnóstico requiere un alto índice de sospecha clínica. La cirugía abierta se mantiene como el gold standard, sin embargo, en población pediátrica estaría indicada la resolución endoscópica debido a la alta morbilidad de la cirugía tradicional.
Introduction: Pyriform sinus fistula is a rare cervical branchial anomaly derived from the third and fourth branchial arch. Pyriform sinus fistula should be considered in children presenting enlarged neck mass, fistula, abscess, thyroid infection and/or dysphonia. Objective: We here report 4 cases treated in Hospital Clínico Universidad de Chile and review of the current literature on pyriform sinus fistula. Discussion: When clinical presentation is compatible with pyriform sinus fistula, endoscopic and imaging techniques are required. Surgical outcomes are better, although endoscopic therapies and combination of both surgery and endoscopy have also reported good outcomes. Conclusion: Diagnosis is made based on signs and symptoms and a high index of clinical suspicion. Open surgery is gold standard, however in pediatric population endoscopic resolution should be considered to reduce the high morbidity of traditional surgery.
