Summary
Combined impedance-manometry offers enhanced oesophageal motility testing by monitoring bolus transport and LES relaxation without radiation. This novel technology improves diagnostic accuracy for oesophageal function disorders.
Area of Science:
- Gastroenterology
- Physiology
Background:
- Oesophageal manometry is the standard for assessing oesophageal motility.
- Conventional manometry lacks direct information on bolus transit.
Purpose of the Study:
- To review the novel technology of combined impedance-manometry for oesophageal motility testing.
- To highlight the advantages of combined impedance-manometry over conventional manometry.
Main Methods:
- Review of recent studies on combined impedance-manometry.
- Focus on the capabilities of the novel technology.
Main Results:
- Combined impedance-manometry provides additional information on oesophageal motility.
- It enables radiation-free monitoring of bolus transport patterns.
- It allows calculation of bolus transit parameters and evaluation of bolus clearance.
- It investigates relationships between bolus transit and lower oesophageal sphincter (LES) relaxation.
Conclusions:
- Combined impedance-manometry offers significant advantages over conventional oesophageal manometry.
- This technology has the potential to improve diagnostic accuracy in oesophageal motility testing.
- It advances both clinical and basic research in gastroenterology.

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

01:19Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
