Esophageal Manometry Testing and Anti-Reflux Surgery: The Preoperative Necessity and Prognostic Utility

Abstract

Manometric assessment of the gastroesophageal junction (GEJ) and esophageal body is the key to a better understanding of the mechanics of antireflux surgery (ARS) and maximizing its benefits while minimizing adverse outcomes. However, there is an attitude of uncertainty regarding the necessity of esophageal motility prior to ARS among some surgeons. This evidence-based review highlights the critical role of manometry in the preoperative workup for patients undergoing ARS. It also discusses how manometry can detect findings associated with favorable outcomes or the risk of postoperative dysphagia. Manometric data can be used for risk stratification and the prediction of outcomes, aiding the surgeon in matching an operation to the specific physiology of each individual patient.
