Brief Summary:

Anorectal 3D high resolution manometry (3D HRM) is the most advanced version of manometry equipment and has been recently introduced into clinical practice. It is the most precise method to assess the anal sphincter pressure function and may be crucial for planning and controlling surgical procedures of the anorectal area. Normal values in pediatric population have not been established.

The aim of this study is complex evaluation of anorectal function in children without symptoms from lower GI tract and establishment of normal values.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 61 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Evaluation of Anorectal Area in Children Using 3D High Resolution Anorectal Manometry.
Study Start Date : April 2013
Actual Primary Completion Date : November 2015
Actual Study Completion Date : November 2015

Arm Intervention/treatment
children without anorectal disorders
All children will be investigated by 3D high resolution anorectal manometry procedure
Device: 3D high resolution anorectal manometry
Procedure will take about 15 min. During procedure resting, voluntary squeeze, bear down maneuver, cough reflex, ano-anal reflex and Rectoanal Inhibitory Reflex will be obtained, if possible.

Primary Outcome Measures :
  1. Mean and maximum sphincters pressures during rest, voluntary squeeze and bear down maneuvers and Asymmetry of the anal canal [ Time Frame: up to 20 minutes ]
    Pressures during voluntary maneuvers will be obtained if cooperation with a child will be possible

Secondary Outcome Measures :
  1. Presence of Rectoanal Inhibitory Reflex [ Time Frame: up to 5 minutes ]
    Amount of air in a balloon needed to elicit Rectoanal Inhibitory Reflex

  2. Presence of dyssynergic defecation [ Time Frame: up to 1 minute ]
    Percent of children without constipation but with dyssynergic defecation pattern

  3. Presence of Cough Reflex [ Time Frame: 10 seconds ]
  4. Presence of Ano-anal Reflex [ Time Frame: 10 seconds ]
  5. Presence of discomfort during the procedure [ Time Frame: up to 20 minutes ]
