Preoperative Diagnostic Workup before Antireflux Surgery: An Evidence and Experience-Based Consensus of the Esophageal Diagnostic Advisory Panel

Abstract

Currently, upper endoscopy, barium esophagram, pH testing, and manometry are required for preoperative workup for antireflux surgery. Additional studies with long-term follow-up are required to evaluate the diagnostic and therapeutic benefit of new technologies, such as oropharyngeal pH testing, multichannel intraluminal impedance, and hypopharyngeal multichannel intraluminal impedance, in the context of patient selection for antireflux surgery.
