Chicago Classification Criteria of Esophageal Motility Disorders (EPT)

Chicago Classification Criteria of Esophageal Motility Disorders Defined in High Resolution Esophageal Pressure Topography (EPT)

High resolution esophageal pressure topography (EPT) is an evolutionary technology incorporating the combination of high resolution manometry (HRM) and pressure topography plotting in the form of Clouse plots introduced in 2000 for the clinical evaluation of esophageal motility. Prior to that, EPT had been developed and utilized as a highly innovative research modality. The HRM Working Group first met in San Diego during DDW 2007 with the objective of adapting EPT to the clinical evaluation of esophageal motility. Since then, a series of HRM Working Group meetings have ensued on a more-or-less annual basis to review, critique, and plan the iterative process of developing a practical classification for esophageal motility disorders based on EPT-specific metrics and criteria. The classification scheme was initially branded 'The Chicago Classification' in 2007 following a series of seminal publications defining key EPT metrics and interpretation criteria optimized for clinical EPT studies emanating from a group of investigators at Northwestern University in Chicago. Since then, two iterations of the Chicago Classification have been published summarizing the incremental development of the classification scheme. The most recent meeting of the HRM Working Group was in Ascona, Switzerland in conjunction an international congress focused on the clinical evaluation of esophageal disease. This paper summarizes the Chicago Classification of esophageal motility disorders emanating from the meeting at the Ascona congress.

BSG guidance on the use of faecal calprotectin testing in IBD

Updated guidance document on use of faecal calprotectin – both in assessment of GI symptoms, and also in patients with known IBD.

Dr Barney Hawthorne, Chair BSG IBD Section Committee, October 2016.

Differentiation between inflammatory bowel disease (IBD) and functional gut disorders, and the determination of mucosal disease activity in established cases of IBD remain the cornerstones of disease diagnosis and management. Non-invasive, accurate biomarkers of gut inflammation are needed due to the variability of symptoms, the inaccuracies of currently available blood markers and the cost and invasive nature of endoscopy. Numerous biomarkers have been used and/or considered with some in current use...

Cancer Genetics in Clinical Practice

A Guide to Cancer Genetics in Clinical Practice

A Guide to Cancer Genetics in Clinical Practice

BSG member Sue Clark has recently published a new textbook 'A GUIDE TO CANCER GENETICS IN CLINICAL PRACTICE' which has a significant gastroenterology content.

This book covers the basic concepts of cancer genetics. The common inherited cancer syndromes are each dealt with in greater depth, with the current management outlined. It is aimed at all clinicians who may encounter these conditions in their practice. The book sets out to facilitate identification of high-risk individuals and families, to inform interaction with geneticists and other sub-specialists, to provide a basis for patient management and to stimulate interest in these fascinating conditions.
