several years post-colostomy reversal question

I"m usually on the CP forum but had a question (sorry for TMI)
I had a temp. colostomy after a Trauma but was able to have it reversed about 6 weeks after.
But since then, I have an issue having a BM. I often have to push on the area between the rectum and lady parts or actually do "manual removal" to get it out. This had been constant since the surgery. They don't know if its trauma related or surgery related. most just say its not an issue and I deal with it...but is this normal?

Your question was nine months ago. I have the same problem. My sitz marker test came back with residue in the small bowel that should have eliminated. Did you find out anything in the last nine months? I would like to know if small bowel motility is behind our problem . I don't want additional surgery. I'm scheduled for defecocraphy. I guess it checks muscles or nerves in the rectum. I know its just a laxative solution so I would like to cancel the test. Its invasive and expensive. If the small bowel is not moving fast enough then the rectum and muscles and nerves in the rectum are likely not the issue.
