Colonoscopy Through the Stoma: A patient’s perspective (12 pages) – a nice overview of having a colonoscopy through the stoma, published by Colostomy UK.
Having a colonoscopy through a stoma: A guide to the test (20 pages) – Lots of details in this step-by-step guide. It was written for patients of the Sheffield Teaching Hospitals in the UK, so your own hospital’s protocol might vary slightly – but not significantly. Most important is that it will probably answer all your questions about what happens before, during, and after the procedure.
