Rectal Physiologic testing
Rectal physiologic testing: The release of stool from the digestive tract requires a series of coordinated contractions of the rectum and relaxation of the internal and external anal sphincters. Damage to the nerves or muscles can lead to pelvic pain, constipation, and/or incontinence of the stools. Physiologic testing involves:
1)Anorectal manometry – measures rectal and anal contractions as well as anorectal sensation and the sphincter reflexes
2)Pudendal nerve testing – measures the function of the main nerve controlling the anal sphincter
3)Anorectal ultrasound – investigates the integrity of internal and external anal sphincters and well as the rectum
4)Flexible sigmoidoscopy – investigates for rectal and sigmoid diseases
The results of these tests will help guide therapy which can include:
- Pelvic floor physiotherapy: Strengthening and sensation conditioning
- Endoscopic interventions – polyp removal, haemorrhoid treatment
- Surgery: anal sphincter remain, rectal prolapse remain
- Medications – ointments, laxatives, and suppositories
