Endoanal ultrasonography with 3D reconstruction
As with any other form of ultrasound examination, the endoanal ultrasound examination is performed using special probes inserted into the anus. This has the advantage of examining the tissues around the anus more closely. This 2D examination is now supplanted by a sophisticated machine which combines 200 or more serial 2D images into a 3D volume image, allowing more precise visualization of the anus and any disease around it, e.g. fistula tract. When we can see better, we can plan and treat it better!
Anorectal manometry is an important diagnostic tool used in the assessment of faecal incontinence and chronic constipation. It is a test that measures how well the rectum and anal sphincters work together to eliminate stool (faeces). The anal sphincter has an internal and external sphincter, or valve, which helps to control continence (passing) of stool. These valves are made of muscles that control the opening and closing of the anus. The test is performed to see how well it is working.
Muscle transposition and graciloplasty
This involves moving one of the strap muscles of the thigh and wrapping it around the anal sphincter to improve the function.
Artificial bowel sphincter implantation
Implanting a special water-filled cuff device around the anal sphincter to improve incontinence.
