High resolution oesophageal manometry: addressing thermal drift

Oesophageal high-resolution manometry: moving from research into clinical practice.

Manometry measures pressure within the oesophageal lumen and sphincters, and provides an assessment of the neuromuscular activity that dictates function in health and disease. It is performed to investigate the cause of functional dysphagia, unexplained "non-cardiac" chest pain, and in the pre-operative work-up of patients referred for anti-reflux surgery. Manometric techniques have improved in...

Chronic Cough in Musculoskeletal disorders: Using high resolution oesophageal manometry in search of an Aetiology

Chronic cough is a common symptom carrying significant morbidity which can occur as a result of oesophageal dysmotility. Here we report 2 patients with musculoskeletal disease presenting with chronic cough to our tertiary cough clinic. Prior to referral both patients had been extensively investigated to determine the basis of their cough, with no cause found. Oesophageal studies, using high res...

Recent Concept in Interpreting High-Resolution Manometry

Esophageal manometry is considered the gold standard for assessing esophageal motor function. Although conventional manometry has been widely used to evaluate esophageal motor function, this is not fully satisfactory for explaining esophageal symptoms. High-resolution manometry (HRM) is designed to overcome the limitations of conventional manometric systems with advanced technologies. A solid-s...

Event Prediction in Pharyngeal High-Resolution Manometry

A prolonged phase of increased pressure in the upper esophageal sphincter (UES) after swallowing might result in globus sensation. Therefore, it is important to evaluate restitution times of the UES in order to distinguish physiologic from impaired swallow associated activities. Estimating the event t where the UES has returned to its resting pressure after swallowing can be accomplished by pre...
