Abstract

Pharyngolaryngeal reflux has been generally accepted as a cause for pharyngolaryngitis, hoarseness, aspiration pneumonia, chronic cough, and nocturnal asthma. Although patients who have undergone gastric conduit reconstruction after esophagectomy are at a high risk to pharyngolaryngeal reflux disease (PLRD), PLRD after esophagectomy is still unknown. The aim of this study is to investigate the correlation between reflux pharyngolaryngitis and acid reflux into the hypopharynx and into the cervical esophagus in patients who have undergone cervical esophagogastrostomy. We enrolled 62 patients who received follow-up endoscopy and 24-h pH monitoring after cervical esophagogastrostomy. These included 26 at 1 month after surgery and 36 at 1 year or more after surgery. We investigated: (i) the correlation between the extent of reflux pharyngolaryngitis and that of reflux esophagitis based on endoscopic findings; and (ii) the correlation between the extent of reflux pharyngolaryngitis and that of acid exposure -'% time pH < 4' measured by 24-h pH monitoring - in the hypopharynx and in the cervical esophagus, and of acidity in the gastric conduit. There was no difference in acid exposure between the hypopharynx and the cervical esophagus...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
