Among spinal and epidural anesthesia, which is recommended for uterine polyp removal?

Hello doctor,

My gynecologist removed most of a polyp in her office with a local anesthetic and NSAID shot. However bits are still attached to the uterine wall because she was afraid of puncturing wall if I move. I had a colonoscopy with Propofol and had only had a bit of dizziness when I stood up, but it gone within a minute or two (I actually could have driven myself home). I had wanted to do without anesthetic, but the doctor said there was no way to get a local that far up. However, my gynecologist is afraid I could still move under Propofol and wants a general anesthetic. I only get to talk to an anesthesiologist at the hospital where once I schedule a surgery so I want to find out about perhaps using an epidural or spinal anesthetic. Basically, I want the least amount of anesthetic that will allow me to stay awake but keep my legs from moving. I have a high tolerance for pain. So, can I get some thoughts on this.

I am currently taking Levothyroxine sodium 50 mcg and some vitamin supplements.
