Fístulas del seno piriforme congénitas. Reporte de 4 casos y revisión de la literatura

Abstract

Congenital pyriform sinus fistula. Report of 4 cases and review of the literature 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.

Manejo endoscópico de fistulas del seno piriforme. Reporte de dos casos

“…Como hemos mencionado el manejo quirúrgico tradicional se asocia a disecciones extensas y colocación de colgajos musculares. (4,9,10) En contraste el manejo endoscópico que utilizamos ha mostrado alta efectividad en pacientes pediátricos sin los riesgos que implica la disección extensa. (4,9,11) También se ha reportado el uso de ácido tricloroacético, pero requiere endoscopía rígida y un procedimiento más complejo.…”
