FYI

Anorectal manometry - The pressures generated by the anal muscles are tested at rest and during squeezing. We also measure reflexes that contribute to bowel control and various measures of rectal sensation.
Anal Ultrasound � Anorectal ultrasound is a very useful tool for imaging the anatomy of the anal sphincters and rectum in patients with a variety of anorectal diseases. It is not an x-ray, therefore there is no radiation exposure. A probe the size of an index finger is inserted into the anal canal and the rectum. Using 'sound waves' produced by the probe, an image is captured on the screen. The patient may feel vibration from the probe during the examination, but discomfort is uncommon. The study takes 15 to 30 minutes.

If they used the ultra sound for analrectal issues, not just the abdomen.

"Outlet obstruction type constipation (pelvic floor dyssynergia)
The external anal sphincter, which is part of the pelvic floor, also normally stays tightly closed to prevent leakage. When you try to have a bowel movement, however, this sphincter has to open to allow the fecal material to come out. Some people have trouble relaxing the sphincter muscle when they are straining to have a bowel movement, or they may actually squeeze the sphincter more tightly shut when straining. This produces symptoms of constipation."
