I've been watching Dr Pimple Popper, and she removes massive lipomas under LA. Which reminds me that I have always wondered why I had mine removed under GA.
A few years ago I had a 3cm lipoma removed from my shoulder. I was having pain in my arm and neck, especially when the lipoma was pressed by a bra strap or shoulder bag.
I was referred to a GP who did minor surgery. He was going to remove it under local anaesthetic. He warned me that, if the tumour was too close to the major nerve or blood vessel, he would have to close me up again and refer me to a specialist surgeon (orthopaedics IIRC). I refused the surgery and asked to be referred there and then.
The specialist decided to remove the lipoma in hospital. Ultrasound scan had shown that the lipoma was unlikely to involve any important tissues, though this was not guaranteed. This time I felt I was in expert, safe hands, and was not worried.
On the morning of the surgery, when the surgeon came to say hello and draw all over my shoulder with permanent marker, he told me I was going to have GA (I had been told to fast beforehand, in any case). I asked if I could have the surgery under LA, explaining that I was not anxious about it. Surgeon was quite firm that it had to be GA. I accepted this, and the surgery went ahead with no problems.
Thing is, GA always messes with my head, and I'm loopy for up to a week after it. So I do not know whether my question was ever answered: why did the specialist insist on a GA?
