  Purpose

High Resolution Manometry is a new technology that utilizes 36 solid state sensors on a thin catheter spaced at 1-cm intervals. One can more effectively measure the pressure of the esophagus. It includes a sophisticated software to display the pressures data as color topography plot using time, length of the esophagus and pressure within the entire esophagus. It is unclear if this technology improvement actually correlates with patient's symptoms.

Primary Outcome Measures:
  • Differences and similarities in patients with achalasia [ Time Frame: at 24 months ] [ Designated as safety issue: No ]
    To determine the differences and similarities in the clinical presentation of patients with type 1, 2 and 3 achalasia based on the Chicago classification for HRM


Secondary Outcome Measures:
  • Esophageal dysmotility in patients with dysphagia and GERD symptoms [ Time Frame: at 24 months ] [ Designated as safety issue: No ]
    To determine the prevalence of esophageal dysmotility using the Chicago classification based on primary chief complaints.

  • HRM parameters [ Time Frame: at 24 months ] [ Designated as safety issue: No ]
    To determine if HRM parameters reflect esophageal physiology between contractile strength of the esophagus and GEJ residual pressure obstructing esophageal flow.

  • Esophageal dysmotility in patients with postfundoplication compliants [ Time Frame: at 24 months ] [ Designated as safety issue: No ]
    To determine the prevalence of esophageal dysmotility using the Chicago classification based in patients with postfundoplication complaints.

  • Correlation between HRM and symptoms [ Time Frame: At 24 months ] [ Designated as safety issue: No ]
    To determine if HRM parameters reflect symptom presentations.

Detailed Description:

In a 2007 retrospective study performed using this technology, 400 subjects referred to the motility lab underwent high resolution manometry (HRM) for complaints of dysphasia, gastroesophageal reflux disease, chest pain and miscellaneous complaints. HRM offered greater detail of individual contracting segments of the esophagus, including the duration of contraction and propagation of individual contractions.

For example, a new subclass of achalasia was defined by HRM. In this classification, achalasia is divided into types 1, 2 and 3. Type 1 corresponds to classic achalasia (complete esophageal motor failure), type 2 is a compression achalasia (simultaneous panesophageal pressurization with aperistalsis), and type 3 is spastic achalasia with aperistalsis (100% spasm). However, it is unclear if this categorization represents a spectrum of disease among patients with achalasia, or it represents distinct subgroups of patients with different symptom presentation and etiology.

This study will attempt to correlate the data from HRM to patient's chief compliants, symptom severity, and clinical presentation.
