Laser excision of GOO blockage possible?

First, I've got dudenal GOO and my doc wants to do a bypass as serial balloon dilation hasn't been effective and I'm living on Ensure and chicken broth.

Why can't the laser remove my obstructive ulcer growth, just as is done for colon polyps and cancerous duodenum growths?

I had a monster colonic polyp removed with no problems, so why not the ulcer?

Second, is anyone aware of a university or clinic or doctor that is doing laser abolation for neoplasm removal in the USA?

Many do laser work to control bleeding but bleeding is not present.
