[Recent topics in the medical treatment of reflux esophagitis].

Reflux esophagitis is one of the most common disorders of the upper gastrointestinal tract. It can lead to obstruction through stricture formation, in more severe form to bleeding through ulceration, and to cancer development through the association of Barrett's esophagus. The vast majority of esophagitis can be managed medically. Medical management is separated into two categories: (1) life style modification and (2) drug therapy. Drug therapy includes antacids, prokinetics, sucralfate, H2 receptor antagonists (H2-RAs) and proton pump inhibitors (PPIs). Among these, antisecretory therapy is the mainstay for the treatment. PPIs are shown to be superior to H2-RAs in healing of esophagitis and symptom relief. Recurrence, particularly of erosive esophagitis, is common without maintenance therapy. PPIs are also consistently superior to H2-RAs in maintenance of esophagitis healing. Interestingly, a recent report has suggested that curing Helicobacter pylori infection may provoke reflux esophagitis, raising the possibility that the gastroesophageal reflux diseases become more common in the future. Therefore, treatment strategy for reflux esophagitis needs to be re-established in terms of the future cost-effectiveness evaluation and quality-of-life assessments.
