Pouchoscopy is an annual event for me to biopsy for CA screening (I had high grade dysplasia, mucosectomy was done, so no cuff left, but the surgeon still wanted annual scoping) It's done also to treat recurring prolapse in the pouch lining which causes SIBO type issues and incomplete emptying/leaking. So I get bands every year so far - 3rd time was this week.
Prep is Gatorade and Miralax, plus clear liquids the day before. I was never very good about having frequent colonoscopies when I had UC, but don't mind the annual scope now. It's good to know what's happening in there!
