Surgery of gastroesophageal reflux disease: a competitive or complementary procedure?

The management of chronic gastroesophageal reflux disease (GERD) has both been simplified and immensely improved by the development of modern medical therapies. These are built entirely on the concept of profound acid inhibition, which is very successful in a substantial proportion of GERD patients. Despite the efficacy of proton pump inhibitors (PPIs) some failures are unavoidable, and some patients experience incomplete control of major GERD symptoms on ordinary dosing of PPIs. Although the safety profile of PPIs is very reassuring, some people express some concern about the safety of drug treatment extending beyond 10 years especially when alternative therapeutic strategies are available. Some patients complain of alleged respiratory complications to severe reflux, and in those situations as well as in cases with e.g. Barrett's esophagus, a complete control of reflux also incorporating the duodenal components in the refluxate may be warranted. In all those situations antireflux surgery can be considered indicated for the treatment of chronic GERD and thus be looked upon as complementary to medical therapy. Furthermore, some patients who have their GERD symptoms under control on PPIs still want to have an operation to avoid dependency on drugs. Hence in none of these clinical situations does antireflux surgery play a competitive role in relation to medical therapy. However, in the very few randomized clinical trials in which a head-to-head comparison has been completed between medical and surgical therapy, the latter has been found to be somewhat more effective in terms of reflux control. The other side of the coin is that antireflux surgery has some side effects that signify the importance of this surgery being performed in specialized centers. Copyright 2004 S. Karger AG, Basel
