Overview

High-resolution Manometry (HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors. For a Manometry system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most 1 cm apart. Two dominant pressure transduction technologies are used: solid state pressure sensors and water perused pressure sensors.

Each pressure transduction technology has its own inherent advantages and disadvantages. HRM systems also require advanced computer hardware and software to store and analyze the Manometry data.
WE CAN PERFORM BOTH ESOPHAGEAL MANOMETRY AND ANORECTAL MANOMETRY ON SAME HARDWARE, ONLY CATHETER & SOFTWARE IS DIFFERENT.

Esophageal Manometry

Esophageal Manometry (muh-NOM-uh-tree) is a test that shows whether your esophagus is working properly. The esophagus is a long, muscular tube that connects your throat to your stomach. When you swallow, your esophagus contracts and pushes food into your stomach. Esophageal Manometry measures the contractions. The test also measures the force and coordination of esophageal muscles as they move food to your stomach. During esophageal Manometry, a thin, flexible tube (catheter) that contains pressure sensors is passed through your nose, down your esophagus and into your stomach. Esophageal Manometry can be helpful in diagnosing certain disorders that can affect your esophagus.
Esophageal manometry is used to check whether the muscles in the esophagus are working properly. When the muscles don’t work as they should, you may experience symptoms such as heartburn, trouble or pain when swallowing, chest pain and regurgitation (food coming back up after swallowing).


Esophageal manometry helps determine what is causing these symptoms,

which could be conditions such as:

Achalasia (esophagus muscles don’t help move food down and prevent food from entering stomach)

Diffuse esophageal spasm (esophagus muscles contract randomly and interfere with swallowing)

Scleroderma (a rare disease that may cause some esophagus muscles to stop moving)

Anorectal Manometry

Anorectal manometry is a noninvasive procedure to evaluate the function of the rectal and anal muscles. This group of muscles, called the anorectal sphincter, controls how stool is released from your body. Anorectal manometry can help determine if these muscles are too loose, too tight or are not engaging at the right moment. This test measures the pressures created by the muscles, the sensation in the rectum (the passageway between the large intestine and the anus), and the neural reflexes necessary for normal bowel movements.
Coordination between specialized muscles and nerves in the rectum and anal canal is essential for bowel movements. Weak or untimely contractions of the anal sphincter muscles can lead to fecal incontinence, while tight muscles during pushing may contribute to constipation. Anorectal manometry is a diagnostic test for conditions like fecal incontinence and constipation. If you're experiencing persistent bowel issues, your doctor may suggest anorectal manometry.

Anorectal manometry can also be used to evaluate people with:

Malformations or injuries of the anus or rectum affecting nearby nerves or muscles.

Hirschsprung’s disease, a condition that is present at birth, and affects the muscles of the bowel.

Irritable bowel syndrome, a condition that involves both diarrhea and constipation.

Rectal cancer if it was treated with procedures that affect the function of anorectal muscles.

A catheter with a balloon on the end that gets inserted into the anus and rectum.

A device connected to the catheter that allows a technician to change the pressure in the balloon by inflating and deflating it, usually with air.

Computer software connected to the pressure device that controls the test settings and records data from the balloon.

The test usually takes about 30 minutes. Before the procedure, you will need to make sure your digestive tract is empty. Your doctor may recommend using one or more over-the- counter enemas at home before the test.

You will need to undress from the waist down or change into a hospital gown, as instructed by the technician or nurse performing the test. A technician will explain the procedure, take a brief health history and answer your questions.

You lie down on your left side and bring your knees up into a fetal position.

Before starting the anorectal manometry test, the technician may first perform a digital rectal exam by inserting a gloved finger into the anus to feel for abnormalities.

A small, flexible, lubricated tube, about the size of a thermometer, with a deflated balloon at the end is inserted into the rectum. The tube is connected to a machine that measures pressure.

The technician will position the balloon at various depths inside the rectum and take several benchmark pressure readings.

The technician will then inflate the balloon to a certain size and ask you to squeeze, relax, push or cough for brief intervals of time. These activities are repeated with different balloon sizes or positions in the rectum. The anal sphincter muscle pressures are measured each time.

To squeeze, you tighten the sphincter muscles as if trying to prevent anything from coming out. Coughing also contracts your anal sphincter.

To push or strain, you bear down as if you are trying to have a bowel movement.

The technician might also ask you if the sensation in your rectum changes with different balloon sizes. You will need to say when it feels like you need to have a bowel movement.

When the test is finished, the technician deflates and removes the balloon.

After the examination, you may drive yourself home and go about your normal activities.

Anal Manometry Test Results

Test results can help your doctor identify the cause of constipation or incontinence and inform a treatment plan.

For instance, the test may reveal weak anal sphincter muscles or poor sensation in the rectum that can contribute to fecal incontinence. These problems can be treated. Biofeedback techniques using anal manometry and special exercises of the pelvic floor muscles can strengthen the muscles and improve sensation.

Test results may show that the anal sphincter muscles do not relax appropriately when you are pushing to have a bowel movement, which may cause constipation. These muscles, too, can be retrained with biofeedback techniques.

BIO FEEDBACK

Biofeedback for anorectal manometry is a therapeutic technique used to treat conditions related to dysfunction of the anal sphincter muscles and pelvic floor. Anorectal manometry is a diagnostic test used to evaluate the function of the rectum and anal sphincter muscles by measuring pressures and reflexes in the rectum and anus.The goal of biofeedback therapy is to teach patients how to improve the coordination and strength of their pelvic floor muscles and anal sphincter muscles. This can help alleviate symptoms associated with conditions such as fecal incontinence, constipation, and pelvic floor dysfunction.
Biofeedback for anorectal manometry is typically performed by a trained therapist in a clinical setting. The therapist will work with the patient to develop a personalized treatment plan that may include exercises, relaxation techniques, and behavioral modifications to improve muscle function and control.
Overall, biofeedback therapy for anorectal manometry can be an effective non-invasive treatment option for individuals experiencing pelvic floor dysfunction and related symptoms.

Antroduodenal Manometry

The antrum is the lower part of the stomach. The duodenum is the first portion of the small intestines. The antrum of the stomach and the duodenum are connected by a muscle called the pyloric sphincter.
Manometry is the study of pressure. Antroduodenal manometry is a way to measure and identify any abnormalities in the coordination and strength of the muscle contractions in the stomach and the duodenum.
Abnormalities in strength or coordination of contractions may cause improper digestion. This may result in symptoms including loss of appetite, nausea, gagging, vomiting, abdominal distention, abdominal pain, diarrhea, and constipation.
You will be asked not to eat for several hours before testing begins.

The doctor will pass a flexible plastic tube through the nose, down the throat into the stomach, and finally into the small intestine. The tube does not interfere with breathing. If you have a gastrostomy, the manometry tube may be placed through the gastrostomy.

The tube has holes at regular spaces, that measure pressure at different places in the stomach and duodenum.

Once properly placed, the tube is carefully secured with tape to the nose or gastrostomy site.

Because sedation and stress affect the contractions of the stomach and intestines, the measurement of pressure will start after you are fully recovered from the catheter placement.

The antroduodenal-manometry tube is connected to a machine that slowly pushes water through each hole in the tube. The machine then records the pressures against the water trying to flow out of the tube.

Recordings are continued during four to five hours of fasting, then you are given a meal. After the meal, the recordings are continued for another one or two hours. From start to finish, the measurement of pressures usually takes six hours. Medication may be given throughout the test to measure their effect on gastrointestinal motility.

While the tube is in place, you will be restricted in activity. Watching TV or reading, as well as storytelling and quiet play for children, are all encouraged. A parent may stay with a child throughout the test.

The measurement of pressure during the antroduodenal-manometry is painless; you will not feel the tube inside your stomach and intestine.

SOLID STATE MANOMETRY

Solid state manometry is a medical diagnostic technique used to measure pressures within various parts of the body, particularly in the gastrointestinal (GI) tract. Unlike traditional water-perfused manometry systems, which use fluid-filled catheters to measure pressures, solid-state manometry employs solid-state sensors to detect pressure changes.
In solid-state manometry, small sensors or transducers are placed at specific locations within the body, usually through a catheter. These sensors can directly measure pressure variations without the need for fluid-filled tubes. The data collected from these sensors are then transmitted to a computer for analysis.

Greater accuracy: Solid-state sensors provide more precise and reliable pressure measurements compared to fluid-filled catheters, as they are less susceptible to fluid inertia and compliance issues.

Increased patient comfort: Solid-state catheters are typically thinner and more flexible than their fluid-filled counterparts, making them more comfortable for patients during the procedure.

Enhanced mobility: Solid-state manometry systems are often more compact and portable, allowing for easier transport and use in various clinical settings.

Reduced risk of contamination: Since solid-state catheters do not require fluid, there is a lower risk of contamination or infection during the procedure.

Provides a continuous and dynamic measurement of pressure changes along the length of the esophagus.

Offers a higher resolution, allowing for more detailed assessment of motility patterns.

Can measure both the amplitude and duration of pressure waves accurately.

Less affected by movement artifacts due to its dynamic measurement.

Can be used for both diagnostic and therapeutic purposes, such as identifying abnormalities in esophageal motility and guiding interventions.
