You may well have post operative adhesions.
These can cause transient obstructive symptoms - colicky abdominal pains that are intermittent, inability to keep anything down, symptoms suddenly appearing or disappearing. Adhesions may occur after any type of abdominal surgery. Unfortunately, the PR bleeding doesn't fit with this. If bright red, it may just be something local such as piles; if altered (black, foul smelling) it is melaena and representative of bleeding from higher up in the gut.

Your doctors are being cocks; the best way to play it is ask if change in bowel habit and PR bleeding are normal, what is the specific diagnosis, and when are you having an abdominal CT...
