Not concerned about
Crohn's Virdent I think that is what the surgeon recommends.
I asked to be for a knocked out for my sigmoidoscopy and they had no problem the surgeon came into the room and said the test I had last week enema x-ray showed narrowing in the anus so she would have to stretch the inside. They said I would feel a slight discomfort. I found out afterward they gave me extra sedation during the test because they had to insert a balloon inside to stretch it 7mm. I didn't feel a thing I don't remember the car ride home and I slept it off for 4 hours. So overall it wasn't that bad. I had extreme discomfort last night and this morning just popping Tylenol for the pain now. Surgery is booked for Aug 8.
Good luck 3timechamp and 100% yes to sedation.
