Conventional anorectal manometry

Anorectal manometry is a fundamental test for the precise evaluation of the functionality of the anal sphincters and of the rectum. Anorectal manometry is in fact the only diagnostic test which allows for measuring the rectal sensitivity and the pressures and reflexes of anal sphincters.

However, traditional anorectal manometry is an uncomfortable test which is generally performed by liquid multi-channel transduction using a very cumbersome device. Furthermore, the specialist must often carry out the examination in a separate laboratory and the clinical evaluation of the patient is normally performed by another specialist at a later stage.

In addition to these aspects, conventional anorectal manometry has other limitations, including:

  • a need to calibrate the catheters
  • a very wide range of values considered normal and abnormal
  • difficulty in interpreting data

THD® Anopress: a new approach to anorectal manometry

THD® Anopress is an innovative portable anorectal manometer which overcomes many of the limitations associated with traditional anal manometry. THD® Anopress allows to correlate the collected data to the patient's symptoms in a simple and fast way, making standardised and replicable pressure values immediately available.

In this way, the specialist performing the exam can immediately evaluate the results and associate them to different pathological conditions. The association between the results of the manometry and specific colorectal diseases is based on the interpretation of a curve which describes the sphincter activity at different times.

The THD® Anopress portable system consists of an anorectal manometer with dedicated software and single-use probes specially developed for use with the THD® Anopress manometer.

THD® Anopress

The THD® Anopress manometer is compact, lightweight, battery operated and is compatible with most PCs. The manometer can be connected via Bluetooth to many PCs and laptops both for storing and sharing data and for printing.

THD® Anopress is equipped with an LED screen which shows pressure values from a numerical and morphological point of view in real time. The controls on the manometer panel allow you to easily manage the different stages of the exam.

THD® PressProbe and THD® SensyProbe

The THD® Anopress system includes single-use probes, specially designed to be used in combination with the THD® Anopress manometer:

  • THD® PressProbe: for the evaluation of the average sphincter tone. The THD® PressProbe has an ergonomic handle and an atraumatic profile to minimise patient discomfort.
  • THD® SensyProbe: for the evaluation of the average sphincter tone, the rectoanal inhibitory reflex (RAIR) and rectal sensitivity. The THD® SensyProbe has an ergonomic handle and an atraumatic profile to minimise patient discomfort.

THD® Anopress software

The THD® Anopress system is equipped with a dedicated software with a user-friendly interface. The software allows the specialist to create medical records for each patient, to keep track of their medical history, to compare current data with previously collected data and to manage further manometric examinations.

The diagrams based on the data collected during the exams show the pressure variations in real time.

THD® Anopress: indications

The most frequent indications for clinical anorectal manometry are:

  • active and passive faecal incontinence.
  • obstructed defecation syndrome.
  • chronic constipation.
  • obstetric damage or post-partum sphincter lesions.
  • lesions of the peripheral nervous system due to trauma, diabetes or sclerosis.
  • pre-operative or post-operative monitoring of sphincter repair operations.
  • pre-operative or post-operative monitoring of surgical operations in the anorectal region (i.e. anal fissures, anal fistulas etc.).
