Brief Summary:

Pressures measured by manometric solid-state catheters may differ according to the type of the catheter and specific anatomy and physiology of anorectum.

The aim of the study is to establish the difference in recordings between 2 types of anorectal catheters used in pediatric patients and to validate the most appropriate way to diagnose of functional disorders.

Condition or disease Intervention/treatment Phase
Constipation Children Fecal Incontinence Device: High-resolution anorectal manometry Not Applicable

Detailed Description:
Patients enrolled in study will be investigated by both types of anorectal catheters, first by anorectal high resolution flexible, thinner, solid-state catheter and after that with rigid, thicker, solid-state catheter. Both procedures will be undertaken during one session. There will be used standard protocol of the procedure that measures conventional manometric parameters (resting pressure, squeeze pressure, bear down manoeuver, thresholds of sensation and recto anal inhibitory reflex threshold.

Official Title: Comparison of High-resolution Anorectal Manometry and 3D High-definition Anorectal Manometry in Diagnosis of Functional Disorders in Children
Actual Study Start Date : March 1, 2018
Estimated Primary Completion Date : March 2019
Estimated Study Completion Date : March 2019

Arm Intervention/treatment
High resolution anorectal manometry
All subjects will be investigated by high-resolution anorectal manometry. At the beginning the anorectal cather will be used to record conventional parameters and after that 3D high-definition anorectal manometric catheter will be inserted in order to measure conventional parameters and 3D picture of anorectum.
Device: High-resolution anorectal manometry
Recording of conventional manometric parameters after insertion of the catheters.

Primary Outcome Measures :
  1. Difference in Resting pressure of the anorectal area [ Time Frame: 20 seconds ]

    Resting pressure will be measured after insertion catheter into anorectum. The software automatically record pressure while patient is lying on the bed.

    The parameter is recorded with 2 different types of anorectal catheters and the difference is evaluated.

Secondary Outcome Measures :
  1. Maximum squeeze pressure [ Time Frame: 1 min ]
    Pressure is recorded after the patient is asked to squeeze anorectum for 20 s (repeated 3 times).

  2. Bear down manoeuver [ Time Frame: 1 min ]
    Pressures are recorded after the patient is asked to bear down for 20 s (repeated 2 times)

  3. Thresholds of sensation [ Time Frame: 1 min ]
    The balloon at the top of the catheter is being filled with air until a patient is able to report sensation, urge and discomfort.

  4. Recto anal inhibitory reflex [ Time Frame: 5 min ]
    The balloon at the top of the catheter is being filled with air until the relaxation of anal sphincter is observed.
