What is the percentage of people who have had complications?

I was wondering how many of you that have had lap RNY have experienced complications and what did they consist of. I am going through the process of seeing my specialists in order to get approved, but I am so scared of any complications ...going under the knife once is bad enough. I am confident of my surgeon (Dr. Pomp) but I'm still a little nervous. Any and all experiences with complications are welcome. And also, thank you in advance for your continued support. Karen
