Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Retrospective analysis for HRM measurements using liquid swallows and a test meal for the presence of hiatal hernia. The investigators will correlate hernia descriptions with presence of acidic reflux and clinical complaints.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will retrospectively analyze all patients referred to hour unit for high-resolution esophageal manometry. These patients have been tested using liquid swallows and a test meal. We will analyze the HRM measurements for presence of manometric signs of hiatal hernia and determine predictive factors for hernia presence. We will correlate hernia description versus presence of acid reflux, clinical complaints and HRM measurements.
