Study summary

Anorectal 3D manometry (3D HRAM) is the most advanced version of manometric equipment that measures pressures along the anal canal in a very detailed manner. It provides complete data about pressure profile of anorectum and may indicate impaired defecation dynamics. Balloon expulsion test (BET) is a cheap, easy way to diagnose constipation as the result of outlet obstruction.

Our aim is to compare this two methods of diagnosis of dyssynergic defecation and to find the correlation between this diagnostic equipment.

Read the detailed description

Patients with the diagnosis of constipation will be enrolled in the study. Each patient will be investigated by anorectal manometry and after the procedure BET will be performed at the same day.

During anorectal manometry conventional manometric parameters will be recorded, such as resting pressure, squeeze pressure, bear down manoeuver, thresholds of sensation and threshold of recto anal inhibitory reflex. 3D picture of anal canal will be recorded.

After the manometry standard BET will be performed. The balloon will be inserted into the rectum and patient will be asked to expel it in private during 1 min.

Data from manometry will be correlated with the success rate of BET.

    All patients will be investigated by anorectal manometry and after the procedure with balloon expulsion test as previously described.

    Device: Manometry

Interventions

  • DeviceManometry

    Each patient will be investigated first by anorectal manometry, standard protocol of conventional parameters will be recorded such as: resting pressure, squeeze pressure, bear down manoeuver, thresholds of sensation and threshold of recto anal inhibitory reflex. 3D picture of anal canal will be recorded. After that balloon with 50 ml of water will be inserted into the rectum and patient will be asked to expel the device within 1 min in privacy.

What researchers measure

Primary outcomes

  1. Correlation between percent of dyssynergic defecation diagnosed by the manometry and BET.

    Percent of patients with the diagnosis of dyssynergic defecation made by BET and according to manometric equipment.

    Time frame: 30 min

Secondary outcomes

  1. Bear down manoeuver pressure differential

    Pressures of rectum and anal canal during bear down manoeuver will be recorded 3 times. Patients will be classified as dyssynergic defecation type. Correlation between the type and the result of BET will be evaluated.

    Time frame: 1 min

  2. puborectalis muscle pressure

    3D picture of anal canal will be recorded and pressure of puborectalis muscle will be recorded during rest and squeeze. The level of pressure will be correlated with the result of BET

    Time frame: 1 min
