HRM Consensus Group

Objectives

The findings of conventional oesophageal manometry as categorized by current classification systems fail to provide a definitive diagnosis or explain the causes of symptoms in the majority of patients referred for investigation.

High resolution manometry (HRM) provides detailed and functionally relevant information about oesophageal motility and function. This information has provided new insights into the physiologic basis of oesophageal function in health and disease.

The HRM Consensus Group was founded to work towards a classification system that:

  • Defines oesophageal dysmotility in terms of its objective effects on function
  • Provides a clear explanation of oesophageal symptoms
  • Identifies abnormal oesophageal motor activity and function that is amenable to specific treatment

This website allows researchers and clinicians working with HRM to get involved with this process. Registered members can take part in on-line studies and upload interesting cases that challenge the existing classification scheme. Active members will be invited to join meetings of the Consensus Group to review study findings, discuss the issues and, we hope, reach consensus on a classification system that both reflects the pathophysiology of oesophageal disease and guides effective clinical management.

Advances in Clinical Investigation of Oesophageal Dysmotility and Gastro-Esophageal Reflux Disease

Introduction to On-line Studies

Inter-Observer Agreement

Inter-observer agreement is essential if high resolution manometry data is to be established as a standard investigation in research and clinical practice.

The current on-line study is designed to assess inter-observer agreement for single 10 ml water swallows based on the provisional Class Definitions published by Pandolfino, Fox, Bredenoord and Kahrilas. Registered users are invited to assess 100 individual swallows from a representative selection of patients referred for investigation of oesophageal symptoms to the University Hospital of Zürich and Northwestern University, Chicago.

This study will be followed by an assessment of the inter-observer reliability for manometric diagnosis based on a set of 10 water swallows. For this study participants will be invited to rate the likelihood of whether HRM findings were accompanied by oesophageal symptoms and to suggest treatment.

XHRM: XML Format for High-Resolution Manometry

By: Dieter Menne, Menne Biomed Consulting, Tübingen

The HRM consensus group has designed an XML based protocol for HRM data exchange and protocol definition which can be downloaded from the addresses below. As of April 7, 2009, all major companies (alphabetically MMS, Sandhill and Sierra) will support the format and are actively working on revisions of the definition.

The full zipped package with the document in Microsoft Word format, the schema file, two sample files and the formal documentation created from the schema can be downloaded here:
