Gastroesophageal Reflux Disease.
Prior to the advent of proton pump inhibitors, internists recommended antireflux surgery primarily for patients whose gastroesophageal reflux disease (GERD) failed to respond to medical therapy. Although many physicians still cling to the notion that antireflux surgery is a procedure best reserved for "medical failures," today this position is inappropriate. Modern medical treatments for GERD are extraordinarily effective in healing reflux esophagitis. It is uncommon to encounter patients with heartburn or esophagitis due to GERD who do not respond to aggressive antisecretory therapy. Indeed, the very diagnosis of GERD must be questioned for patients whose esophageal signs and symptoms are unaffected by the administration of proton pump inhibitors in high dosages. In the large majority of these so-called refractory patients, protracted esophageal pH monitoring reveals good control of acid reflux by the proton pump inhibitors. This finding indicates that the persistent symptoms usually are not due to acid reflux, but to other problems such as functional bowel disorders. Medical treatment fails in such patients because the diagnosis is mistaken, not because the drugs fail to control acid reflux. Modern antireflux surgery also is highly effective for controlling acid reflux, but fundoplication will not be effective for relieving symptoms in patients whose symptoms are not reflux-induced. Therefore, many patients deemed failures of modern medical therapy would be surgical failures as well. Antireflux surgery is an excellent treatment option for patients with documented GERD who respond well to medical therapy, but who wish to avoid the expense, inconvenience, and theoretical risks associated with lifelong medical treatment. Ironically, surgical therapy for GERD today is best reserved for patients who are medical successes.
