Abstract
Objective

Little is known about incidence of laryngopharyngeal reflux (LPR) and gastroesophageal reflux (GER) in the early postoperatory period of laryngectomy. To evaluate the effect and characteristics of the LPR and GER in laryngectomized patients, by means of double pH-metry during the 48hours after surgery.

Material and method

In 50 patients, 48-hour double-probe pH monitoring was performed in postoperative period following laryngectomy, after a intraoperative placement. Descriptive analysis of 4 variables of pH to level of the sensor proximal, and definition of the presence of esofagic reflux and LPR.

Results

The incidence of LPR in the postoperative of laryngectomy ranges between 30% and 40%. A esofagic reflux has been observed in 40%.

Conclusions

A high incidence of LPR and GER in the postoperative immediate of laryngectomized patients was found.

Resumen
Objetivo

Se desconoce la incidencia de reflujo laringofaríngeo (RLF) y de reflujo gastroesofágico (RGE) en el postoperatorio reciente de las laringectomías. Nos propusimos evaluar la incidencia y las características del RLF y el RGE en pacientes laringectomizados, mediante pHmetría de dos canales durante las 48horas posteriores a la cirugía.

Material y método

Estudio prospectivo de 50 pacientes mediante la colocación intraoperatoria de una sonda de pH de dos canales, el análisis descriptivo de cuatro variables de pH a nivel del sensor proximal y definición del RGE y el RLF.

Resultados

La incidencia de RLF en el postoperatorio de los laringectomizados oscila entre el 30 y el 40% y la de RGE, en el 40%.

Conclusiones

El RLF y el RGE se detectan en un porcentaje elevado de pacientes en el postoperatorio inmediato de las laringectomías.
