Evaluation of esophageal function for antireflux surgery.

摘要

Antireflux surgery has become well established as an effective and durable therapy for gastroesophageal reflux disease and its complications. The outcome of antireflux surgery, however, is only as good as the evaluation to document the association between pathologic esophageal acid exposure and the patient's symptoms. This article discusses the well-established diagnostic modalities used to assess foregut structure and function and includes several more sophisticated secondary studies that may aid the clinician in elucidating the cause of the problem in patients in whom standard testing is inadequate.
