"Why was the need for a cannula and drug administration referred to?"

I agreed to sigmoidoscopy because I believed it to be a drug free procedure. Indeed, in none of the literature given to me by the hospital is the need for a cannula and drug administration referred to. The doctor I saw who referred me for the procedure didn't mention it and neither did the nurse I saw in a pre-assessment appointment.

However in late July I attended for my sigmoidoscopy to be told by the nurse that the doctor carrying out the procedure insisted on a cannula for the administration of drugs. I made it clear I didn't want drug administration and the doctor response was to refuse to carry out the procedure so I went home.

I have to say that the nurse I saw in the endoscopy suite was excellent and very apologetic. However I took a day off work so lost money and incurred costs in travelling to and from the hospital unnecessarily. Also, of course, I had prepared myself by using an unnecessary enema before leaving home which I hasten to add resulted in considerable rectal bleeding which hasn't stopped, but nobody seemed interested.

The nurse did kindly say that she would re-arrange an appointment for me with a doctor who didn't require a cannula. Therefore it's obvious this isn't essential

If this requirement had been made known by staff or in literature beforehand, I could have saved my time and money and the hospitals.
