Brief Summary
Ano-rectal manometry is indicative in patients with either fecal incontinence or constipation. Recently anorectal 3D- high resolution manometry has been developed. Pressure variations are measured circumferentially along the anal canal. It may allow a better understanding of anorectal disorders by displaying anal pressure asymmetry and it could be useful to assess the functional anatomy of the pelvic floor better than conventional manometry.

Interventions
Anorectal probe is used with a single-use protective sheath with an inflation balloon Control of balloon deflation Patient in left lateral decubitus position with hips flexed to 90° (this position is the most commonly use and the most convenient) Transanal insertion 2 minutes resting period: resting anal pressure will be evaluated the second minute of rest Sustained voluntary maximal squeeze for at least 30 seconds; the maneuver will be repeated once Valsalva Bear down maneuver; the maneuver will be repeated once Anorectal reflexes evaluation with 20-, 40- and 60-ml intra-rectal balloon inflation Probe removal
Patient in left lateral decubitus position with hips flexed to 90° Transanal probe insertion Evaluation of internal and external anal sphincter integrity and puborectalis muscle at rest
Patient in left lateral decubitus position with hips flexed to 90° Rectum is filled with 50-ml water Probe is covered with a water-filled balloon to maintain the acoustic window for the ultrasound wave Transanal probe insertion Slow and manual rotation of the linear probe through 360° to identify the various layers constituting the anal wall (mucosa, IAS, EAS), the layer forming the rectal wall and the perirectal tissues (puborectalis muscle, bladder, and vagina or prostate) After the initial examination, the patient will be asked to make a defecation effort with the probe left in the same position
