Understanding Anorectal Manometry: A Diagnostic Tool for Bowel Function

What is Anorectal Manometry?

Anorectal manometry is a diagnostic test used to measure the pressure in the rectum and anus during defecation. It helps evaluate the function of the muscles involved in bowel movement.

Why Anorectal Manometry is required?

This test is often performed to:

• Diagnose constipation or fecal incontinence.
• Evaluate the effectiveness of treatments for these conditions.
• Assess the function of the anal sphincters and pelvic floor muscles.
• Identify potential anatomical or neurological abnormalities affecting bowel function.

which are the method of Anorectal Manometry ?

There are two main methods of anorectal manometry:

1. Balloon manometry: A small balloon is inserted into the rectum, and pressure is measured as the balloon is inflated and deflated.
2. Sensing probe manometry: A thin probe with sensors is inserted into the rectum to measure pressure at different points.

 

who should go for Anorectal Manometry ?

Individuals who may benefit from anorectal manometry include:

• People with chronic constipation or diarrhea.
• Those experiencing fecal incontinence.
• Patients undergoing surgery for pelvic floor disorders.
• Individuals with neurological conditions that may affect bowel function.

 What are the results of Anorectal Manometry ? 

The results of anorectal manometry can help identify abnormalities in:

• Rectal pressure: This may be too high or too low.
• Anal sphincter function: The anal sphincters may be weak or not closing properly.
• Pelvic floor muscle coordination: The muscles may not be contracting or relaxing correctly.

What are the components of Anorectal Manometry?

The test typically involves:

• Preparation: You may be asked to fast or avoid certain foods before the test.
• Insertion of the probe: The probe is inserted into the rectum through the anus.
• Pressure measurements: As you contract and relax your pelvic floor muscles, the pressure in the rectum and anus is measured.
• Interpretation of results: A healthcare provider will analyze the results and discuss the findings with you.
