Anorectal Manometry
AM
Description
"Anorectal Manometry" test evaluates how well the rectum and anal muscles work, helping diagnose chronic constipation or fecal incontinence. A small tube with a balloon is gently inserted into the rectum to measure pressure and coordination during muscle contractions. Doctors use the results to assess bowel control, nerve response, or pelvic floor disorders. Findings help guide targeted treatments like biofeedback or dietary changes. Regular testing supports progress tracking and ensures personalized care for long-term digestive health.

Test Group Description
Endoscopic Procedure Group: This group encompasses a range of diagnostic and therapeutic procedures performed using an endoscope, a flexible tube with a camera and light at its tip. These procedures allow healthcare providers to visualize internal organs and tissues, such as the gastrointestinal tract, respiratory system, and urinary tract.
Optimal Range

Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Abscesses (Localized collections of pus)
Anorectal fistulas (Abnormal connections between the anus or rectum and the skin surface)
Constipation (Difficulty passing stool or infrequent bowel movements)
Fecal incontinence (Inability to control bowel movements)
Hemorrhoidectomy (Surgical removal of hemorrhoids)

Key Reasons For Testing
Evaluation of Anorectal Function: Assesses the proper functioning of the rectum and anus.
Diagnosis of Fecal Incontinence: Identifies muscle or nerve issues causing bowel control problems.
Assessment of Rectal Outlet Obstruction: Detects blockages or dysfunction affecting bowel movements.
Guidance for Biofeedback Therapy: Provides targeted insights for pelvic floor rehabilitation.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
