Thanks to Boomer for starting this thread and to all others who contributed. I think if I ever need surgery in the future for an AN, I will strongly consider the endoscopic approach and SBI. My AN appears to be responding very well to CK, but who knows what will happen down the road. I also have a suspected second tumor to deal with, although that's also a candidate for CK.
From what I've read online, it seems the main objection -- whether valid or not -- to endoscopic approach is increased risk of runaway bleeding. I'd like to see data on what percentage of patients undergoing this procedure actually had this problem (i.e., resulting in complications). Then we could better tell if the objections are practical or just theoretical.
In any case, discussions on leading-edge technologies like this are one of the best aspects of this forum. Eventually, I hope, AN treatments will become so refined that none of us will have to go through the post-operative side effects so many of us have reported here.
Best,
TW
