My J-Pouch has essentially failed and I want to try a K-Pouch or BCIR before reverting back to an ostomy. BCIR's are essentially advertised as an upgraded version to the K-Pouch. Is that actually and/or still true, as my subject line asks? Or have have the more experienced K-Pouch surgeons of today matched / surpassed the way BCIR's supposed advantages with their own small "update(s)" to their K-Pouch's? Or have K-Pouch procedures and anatomy therein have never evolved since invented and BCIR's are actually structurally "better"? This is something I haven't been able to find anywhere online or through any doctors, so any input from the people that have subjectively experienced this would be greatly appreciated.
TLDR: K-Pouch vs BCIR-- Which is really better?
