[Study of laryngopharyngeal reflux using pH-metering in immediate post-op of laryngectomized patients].
OBJECTIVE
Little is known about incidence of laryngo-pharyngeal 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 48 hours after surgery.


METHODS
In 50 patients, 48-hour double-probe pH monitoring was performed in postoperative of laringectomy, after a intraoperatory 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 postoperatory of laringectomy ranges between 30% and 40%. A esofagic reflux has been observed in 40%.


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