Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 16 years of experience. I look forward to working with you.
The decision to perform surgery should be based on him (his health overall and how bothered he is by this condition). Usually we turn to surgery when all medications have failed (stool softeners, pro motility drugs, subcutaneous fluid therapy, etc). The surgery does a good job in better than 80% of the cases. An existing dilated bowel as he probably has now can take months to return to function. If he is controlled now with just medications, then I would wait on the surgery and see if he gets some motility back. Probably will not, but if he starts to do very well with no problems, then no hurry.
If you elect surgery subtotal colectomy is the best option for cats that don't respond to medical treatment. It should be done by an experienced surgeon, and although it is a major procedure, it provides a permanent cure. Diarrhea occurs post-operatively for a couple of weeks, or up to 2 months, but generally the procedure works well.
