Is it viable to have internal and external hemorrhoid surgery with just local ansthesia?

Yes : It can be done with just local but i would not recommend it. I would also try to find a non-operative treatment before attempting surgery. Do everything you can to avoid surgery. The recovery is very painful and there are many nonsurgical alternatives that are very effective.

Yes...but: The external hemorrhoids can be numbed using local anesthesia, the inner ones are a little more complicated. However, even if good analgesia is obtained the patient would still be better served by having some sedation, or deep sedation, for the procedure. I would talk with your anesthesiologist about your options. I personally would want to go to sleep for this procedure.
