I was also unhappy about having my 30 year J pouch removed, but recurrent high grade dysplasia and a malignant polyp in the anal canal made pouch removal necessary. I very strongly did not want an ileostomy with its quality of life issues and opted to get a BCIR (very similar to a K pouch). These options do not require having an external bag and there is a lot of information about both procedures in the internet. I have now had a BCIR for 6 years and have had no problems with it.
