Levator Syndrome is chronic spasms in the colon, sometimes very painful. It can also affect urination, and lead to prostatitis-like symptoms (urgency, pain, etc.)

I don't think any test can really detect it -doctors diagnose it through the symptoms.

What are your symptoms?

I have chronic rectal spasms currenlty, but I also had to have surgery for a chronic fissure. My spasms started after about a month of bleeding from the fissure. 2 months post surgery, and I still get them, although in the last couple weeks they havent been too bad. My symptoms are

1. Obvious spasms and contractions in the colon and sphincter
2. A feeling like I have to have a BM, even when I don't
3. Sometimes it spasms during a BM, and I have to push harder, because everything is clenching down.
4. 3 times in the last 4 months, I had painful spasms, when the colon just goes nuts, and I'm incapacitated for about 15-30 minutes. Twice this happened during the night, and once after sex.

Exercise seems to help a bit. When I'm in the gym pumping iron and moving around, I don't notice the spasms.

I've wondered if I have this condition as well. I even had some urinary problems 2 years ago (urgency and frequency) that mysteriously went away after I took some Flomax and modified my diet.
