Gastroesophageal reflux and pulmonary aspiration: incidence, functional abnormality, and results of surgical therapy

C A PellegriniD B Skinner


The incidence of aspiration, the causative esophageal pathophysiology, and the results of surgical therapy were evaluated in 100 patients with abnormal gastroesophageal reflux documented by 24-hour esophageal pH monitoring. Based on historical evidence, 48 patients were suspected to be aspirators. Eight patients had documented episodes of aspiration (drop on esophagela pH, followed by acid taste in mouth and onset of cough or wheezing spell) during the monitoring period. Nine patients were considered to be potential aspirators because they presented oral acid regurgitation without development of pulmonary symptoms. In five patients a primary respiratory disorder (PRD) induced gastroesophageal reflux. The remaining 78 patients had abnormal reflux without aspiartion or regurgitation. Aspirators had a 75% incidence of esophageal motor abnormality on manometry, and the clearance of refluxed acid was significantly delayed in the supine position. A history of heartburn and endoscopic evidence of esophagitis were present in only half of the patients who were documented aspirators. Potential aspirators were spared from aspiration by rapid esophageal clearance of refluxed acid unaffected by changes in body position. Patients with a PRD ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
