Hi Clive, I have had 2 Sigmoids in the last year or so, if you read my Profile updates from 13/4/22 you can get an idea of what to expect through the whole process; after the second one I was diagnosed with radiation proctitis with a couple of diverticulae thrown in for good measure! :). I'm losing a fair bit of blood with most bowel movements. Anyway I've started on Sucralfate enema's now to try and improve things .... though its not easy to administer (its DIY with a syringe!). You can have a sedative with the sigmoid, though I didn't either time and, apart from a bit of cramping, I didn't find it painful. Any questions feel free to get in touch! Rgds, Nick.
