Pouchomarx, it appears that you have made the first major decision: I do not want the bag. Here are my thoughts on your other concerns:
1.You are fortunate to have the Cleveland Clinic nearby. It is definitely a significant plus as far as follow up care, if needed ,which is best provided by the doctors that did your procedure. Plus, there is no travel involved.
2.If you have not already done so, go to the BCIR program website: www. bcir.com. There you will find a lot of information about the BCIR and their services at Palms of Pasadena Hospital. There are a number of other websites on both the BCIR and K pouch that provide additional information.
3.When you meet with your CC surgeon, you should ask him what enhancements they have made to the original K pouch procedure to reduce valve failures and fistula formation (relatively rare occurrences with both procedures) and how he compares it with the BCIR.
4.I was in the hospital in Florida for BCIR for the standard 21 days, which gave sufficient healing time for me to safely travel home to northern Wisconsin and fully care for myself. The time at CC for a K pouch would probably be quite a bit less.
5.I am retired, so return to work was not an issue. However. I had no problems going to an outdoor estate auction that lasted for 4+ hours and involved a one block walk in from where we parked. This event was one week after returning home. For your job, four weeks post-op should be sufficient, but I would consider working half days for your first week. You will have a lifting restriction prescribed by your surgeon.
6.I would think that that a leak repair or pouch redo would be best, provided your surgeon believes there will be a high chance of success.
Best of luck with whatever choice you make.
