Hello sorry to hear of your problems.
I agree with hodaya you need to be very sure your rectum is working ok. also its been a while since you had surgery so are these problems new?
YOu should def not be constipated and you could have narrowing of the part where the join is but dont quote me on it. you really need to talk to your consultant you cannot wait and be suffering.
In the meantime have you tried a glass of warm prune juice in the morning and afternoon? it might help along with the MOM.
