Can't wait for this to become common practice. I have a family Hx of colon cancer and even knowing I am at risk, I will not go for the traditional colonoscopy for several reasons .
#1 As you said, I don't want anything going up the rear.Especially under anesthesia. And fear something will be damaged while probing. Highly invasive procedure.
#2 The uncomfortable clean out procedure and fasting.
#3 Anesthesia
Hurry up!!
