For last 13 years after my surgery i have had a sigmoidoscopy almost every year. I am talking with my GI doc to see if every two years makes sense. However, i just had a flare and i personally feel more comfortable with every year. This is especially true for me as there is history of colon cancer in my family and there is still that small section of colon left for the J-Pouch. so for me better safe than sorry. I tolerate the sig study without drugs or any issues as i have had them so often it is routine for me and I am in and out. Also i participate in any clinical trial to help research this nasty disease to help others, so if they want me in to do something i go.
