Alex,
Although it would be a bit hard to search through them, there are a lot of posts on the board about surgical clips. Another member was going through a removal when I first visited here, which provoked me to ask my surgeon about them.
He explained the use, and used my IGRT planning CT to point them out. It did not seem that he had experienced many problems over the years of open and DaVinci surgeries, but said yes, it is possible.
