The Utility of Esophageal Motility Testing in Gastroesophageal Reflux Disease (GERD).

Purpose Of Review: Here, we discuss how esophageal motor testing plays important roles in patients with suspected gastroesophageal reflux disease (GERD). In addition to guiding appropriate placement of catheters for ambulatory reflux monitoring, esophageal high-resolution manometry (HRM) rules out confounding diagnoses, such as achalasia spectrum disorders, that can present with symptoms similar to that of GERD, but are managed very differently.

Recent Findings: HRM performed with impedance in the post-prandial setting (PP-HRIM) can assess for rumination syndrome or supragastric belching, which should be directed towards behavioral interventions.

Management of Functional Esophagogastric Junction Outflow Obstruction: A Systematic Review.

Goals: Awareness of functional esophagogastric junction outflow obstruction (fEGJOO) has increased, but because there is no consensus on its management, we performed a systematic review of the literature to explore treatment strategies and outcomes.

Background: EGJOO is a heterogenous disorder defined by high-resolution manometry parameters of elevated integrated relaxation pressure with preserved esophageal peristalsis. The etiology may be mechanical obstruction or idiopathic, the latter being fEGJOO.
