After you take a few weeks rest from remedies it is absolutely neseccary to take a full case history. For example what preceeeded the bowell problem in the first place even before the surgery? What csused the rectal prolapse? It seems that you have been looking at the consequences and results, but not finding the cause. What was your emotional state and what happened in your life before this. Was it a chronic condition evolving or was it of quick onset.

It may then be that a remedy like OPIUM might be considered depending on the case history.
RECTUM: SEVERE CONSTIPATION, NO DESIRE FOR STOOL: Round, hard balls

Homeopathy will help more than just the physical manifestation's you have described so give it a real chance to help you. All the best for your health.
