Anorectal Manometry (ARM): Techniques, Benefits, and Best Practices

Published on Mar 6, 2024

Anorectal manometry (ARM) is an essential diagnostic tool used for evaluating the function of the anal sphincters and rectum. ARM can help diagnose and understand disorders like fecal incontinence, constipation, and pelvic floor dysfunction. How can this procedure empower you when treating these disorders in your practice?

Definition and Purpose of Anorectal Manometry

ARM provides valuable information about muscle function by measuring pressures in the anal canal and rectum. This minimally invasive procedure has become a cornerstone in understanding anorectal physiology. The advancements in ARM have revolutionized diagnostic precision, from traditional manometry to high-resolution manometry. ARM aims to assess anorectal function accurately to easily diagnose and plan for treatment.

Techniques of Anorectal Manometry

Catheter Types and Specifications

Different catheter designs cater to various clinical needs, ensuring flexibility and patient comfort during the procedure. The selection of catheters appropriate for a patient is pivotal in obtaining accurate and meaningful data.

Preparation and Positioning

Proper preparation and positioning are vital to getting accurate and reliable results from an ARM examination. Healthcare professionals need to use the correct technique to insert and place the catheter for a successful procedure. Explaining the different tests to the patient as you go is important to help them relax and cooperate to get the best results. This step-by-step process ensures precision and minimizes discomfort for the patient.

Data Acquisition during ARM Procedures

The collection of meaningful data is needed for accurate diagnosis and treatment. Detailed data is also useful when determining a course of treatment for the patient. With ARM systems, like mcompass®, the compact, easy-to-read tablet PC gives simple prompts to guide even first-time users through the entire exam process. After prompted procedures are completed, the patient data appears on the tablet screen to then be analyzed to create a treatment plan.

Interpreting Anorectal Manometry Results

Take the time to familiarize yourself with the expected values and parameters. This will help you interpret the procedure results more effectively. ARM helps identify issues such as impaired sphincter function, rectal or hyposensitivity, and abnormal reflexes. Recognizing the connection between the results and clinical conditions guides effective treatment strategies. Real-world examples showcase how ARM findings translate into clinical decision making, enhancing understanding. View a recent case study here.

Benefits of Anorectal Manometry in Clinical Practice

ARM allows clinics to detect anorectal disorders early on leading to prompt intervention and improved patient outcomes. ARM also increases patient comfort and convenience. Patients are more likely to have a positive experience leading to an increase in compliance with diagnostic protocols.
