title: Gastroesophageal reflux.
abstract: Gastroesophageal reflux disease (GERD) is the most common disease of the gastrointestinal system. Heartburn, regurgitation, and dysphagia are the most common symptoms of GERD. However, chest pain, chronic cough, laryngitis, hoarseness, and other otolaryngologic manifestation can be the primary manifestations of the disease. Endoscopy, barium studies, and especially pH monitoring and therapeutic trials may help in establishing the diagnosis of GERD. The introduction of H2 antagonists and especially of proton pump inhibitors (PPI) has brought symptomatic relief in most patients. However, surgical procedures, especially laparoscopic fundoplication, are still required in some patients. Barrett's esophagitis is the most common complication of GERD and is associated with a high prevalence of esophageal adenocarcinoma. Whether or not treatment with either PPIs or H2 antagonists can prevent this complication is still under investigation.
