Whether you have cuffitis or diversionary pouchitis.. prior to takedown, it can be treated. Cuffitis is inflammataion in the remaining rectal cuff, which is basically UC. Diverionary pouchtis is inflammation resulting from the lack of "nutrients" in the fecal stream going through the pouch. This is said to be completely unrelated to regular pouchitis, after takedown. Having diversionary pouchitis shouldn't be any precursor of pouchitis after takedwon.
Cuffitis can be treated with rectal meds.. even now pre-takedown. I might want to get that under control pre-takedown if it was really causing me trouble.
Diversionary pouchitis - if its causing intense pain, and unrelenting spasms can also be treated. Generally first line of treatment if short chain fatty acid enemas SCFA, if that doesn't work they move up to rowasa enemas.
