high-resolution manometry

[Guest guest]

One of the things people in this support group often recommend is that

people looking for a diagnosis go to better centers that specialize in

esophageal motility disorders. One of the things they are told they may

find there is better manometry equipment with people that have more

expertise in using them and understanding the results. Many doctors may

be using old standard equipment while some centers are now using newer

high-resolution manometry (HRM) and high-resolution esophageal pressure

topography (HREPT) equipment. This newer technology and detailed data it

provides may be changing the understanding and classification of

achalasia and the ability to predict treatment outcomes.

Take a look at these paper's abstracts:

Has high-resolution manometry changed the approach to esophageal

motility disorders?

http://www.ncbi.nlm.nih.gov/pubmed/20502325

" By reproducibly subtyping achalasia into classic achalasia, achalasia

with pressurization, or spastic achalasia with differential responses to

treatment, HRM has potential to predict clinical outcomes. ... Improved,

accurate and reproducible recognition of manometric diagnoses by HRM

will allow the clinician to confidently diagnose esophageal disorders

such as achalasia, direct therapy and predict outcomes. "

Esophageal motor disorders in terms of high-resolution esophageal

pressure topography: what has changed?

http://www.ncbi.nlm.nih.gov/pubmed/20179690

" Ultimately, clinical experience will be the judge, but it seems likely

that HREPT data, along with its well-defined functional implications,

will improve the clinical management of esophageal motility disorders. "

Achalasia: a new clinically relevant classification by high-resolution

manometry.

http://www.ncbi.nlm.nih.gov/pubmed/18722376

" ... 3 distinct patterns of aperistalsis are discernable with

high-resolution manometry (HRM). ... analysis found type II to be a

predictor of positive treatment response, whereas type III and

pretreatment esophageal dilatation were predictive of negative treatment

response. "
