Objetive: To determine the relationship between pharyngolaryngeal reflux and the absence of intra-abdominal portion of the lower esophageal sphincter. Materials and methods: Analitical, prospective study. Evaluating 65 patients referred to the consultation of the Gastroenterology from Consultation of the Otorhinolaryngology diagnosed with reflux pharyngolaryngeal of Medical Teaching Center La Trinidad period January 2013 to November 2014. They were interviewed to assess typical symptoms (heartburn and regurgitation) and atypical symptoms (cough, hawking and hoarseness), esophageal manometry and ambulatory 24 hour esophageal pH monitoring. Two groups were selected to compare: group A with no intra-abdominal portion of the lower esophageal sphincter and group B with presence of intra-abdominal portion of the sphincter upper esophageal. Results: The variables: age, gender, typical symptoms (heartburn and regurgitation) and atypical symptoms (cough, hawking and hoarseness), pressure of the lower esophageal sphinter and the motility of the esophagic body, they were not significant when compared groups. The ambulatory 24 hours esophageal pH monitoring was significant statistically when compared groups, demostrating that the group A had the highest percentage of positive results for pathological reflux. Conclusion: the absence of intra-abdominal portion determined by esophageal manometry is related to the presence of pathological reflux determined by ambulatory 24 hour esophageal pH monitoring, demonstrating that this can be a trigger factor of Gastroesophageal reflux disease and therefore pharyngolaryngeal reflux.
