Can the marshmallow esophagram replace high-resolution manometry as an appropriate screening for esophageal motility prior to anti-reflux surgery?

Backgound: The purpose of our study was to evaluate the use of minimally invasive Marshmallow Swallow Study (MSS) as a preoperative screening technique for patients and correlate marshmallow results with High Resolution Manometry (HRM) results and post-operative dysphagia following antireflux surgery.

Methods: A retrospective electronic chart review of data on 61 adult patients undergoing MSS was completed. Patients were included if they completed the MSS as well as: HRM and/or antireflux surgery.
