Medical management of esophageal reflux

Abstract

Gastroesophageal reflux of varying severity is a common disorder for which medical attention is sought at all levels, from pharmacists to specialist physicians and surgeons. This brief overview represents my current understanding of reflux, its effects on the esophagus and my personal approach to treatment of these disorders. Of necessity, because the literature is so extensive (a Medline search on reflux from 1966 to 1993 yielded over 1500 papers.), I have relied in places on the extensive review by Marks and Richter [1]. My paper emphasizes the evaluation and treatment of patients with symptomatic reflux, esophagitis and its complications. It describes why it is important to grade the disorders so that the treatment used is appropriate to the severity of the disease. The more severe the disease, the more specific the diagnostic information needed and the more exacting the treatment. Various treatments and outcomes of therapy are discussed, and a role for surgery is defined. The essence of effective medical treatment of esophagitis is to reduce acidity of the refluxate to a level outside the optimum proteolytic pH range of pepsin, i.e. greater than pH 3.5.
