ABSTRACT
Abstract

Introduction:

Congenital piriform sinus fistula is a relatively rare type of disease in clinical practice, most occurring during childhood, but doctors have insufficient knowledge regarding this disease, easily misdiagnosing it.

Objectives:

This study aimed to identify the characteristics of deep neck abscess due to congenital piriform sinus fistula in children.

Methods:

We performed a retrospective study of 21 cases from January 2016 to August 2018 in our hospital. The onset age, clinical characteristics, auxiliary examination and clinical treatment of the patients was summarized to analyze the diagnosis, treatment characteristics and prognosis.

Results:

Children from 11 days to 12 years-old were enrolled, with an average age of 3.5 years. Twenty patients had left congenital piriform sinus fistula and 1 had right congenital piriform sinus fistula. Cervical enhanced computed tomography imaging showed gas-liquid equilibrium or air-shadow in the abscesses in 18 cases, and neck ultrasound demonstrated gas echo in the thyroid region in 10 cases. All patients underwent low temperature plasma to seal the internal fistula and returned to the hospital for electronic laryngoscope and neck ultrasound examination at 3 months, 6 months and 1 year after the surgery. No recurrence occurred in any patient.

Conclusion:

Congenital piriform sinus fistula is an important cause of deep neck abscess in children. The presence of purulent gas-liquid equilibrium or air shadow in cervical-enhanced computed tomography or ultrasound suggests a high possibility of the presence of an internal fistula, and endoscopic low temperature ablation can be done at the same time as the diagnostic endoscopy.
RESUMO
Resumo

Introdução:

A fístula congênita do seio piriforme é uma doença relativamente rara na prática clínica; a maioria se manifesta na infância; entretanto, os médicos geralmente têm conhecimento insuficiente sobre essa condição clínica e seu diagnóstico é facilmente feito de forma errônea.

Objetivo:

Identificar as características do abscesso cervical profundo devido à fístula congênita de seio piriforme em crianças.

Método:

Estudo retrospectivo de 21 casos de janeiro de 2016 a agosto de 2018 em nosso hospital. Idade de início, características clínicas, exames auxiliares e tratamento clínico dos pacientes foram resumidos para analisar o diagnóstico, as características do tratamento e o prognóstico.

Resultados:

Foram incluídas crianças de 11 dias a 12 anos, com média de 3,5 anos. Vinte pacientes tinham fístula congênita de seio piriforme no lado esquerdo e um no lado direito; a tomografia computadorizada cervical com contraste mostrava distribuição líquido-gasosa ou sombra aérea nos abscessos em 18 casos. O ultrassom cervical demonstrou eco gasoso na região da tireoide em 10 casos. Todos os pacientes foram submetidos a plasma de baixa temperatura para queimar a fístula interna e retornaram ao hospital para exame com laringoscópio eletrônico e ultrassonografia cervical aos 3 meses, 6 meses e um ano após a cirurgia. Não houve recorrências.

Conclusão:

A fístula congênita de seio piriforme é uma causa importante de abscesso cervical profundo em crianças. A presença de conteúdo líquido-gasoso purulento ou sombra gasosa na tomografia computadorizada ou no ultrassom cervical sugere uma alta possibilidade da presença de uma fístula interna e a ablação endoscópica a baixa temperatura pode ser feita ao mesmo tempo que a endoscopia diagnóstica.
