Hey there experienced LIS'ers and soon-to-have-LIS'ers, do you all happen to know if you are getting (or had) open or closed LIS? Just curious. I'm scheduled for closed LIS myself and am wondering what the conventional/popular type usually is.
There's a brief explanation of both procedures in the "Surgical Technique" section of the Wikipedia entry on LIS:

My understanding is that closed LIS is less invasive and has shorter recovery times but carries a greater risk of infection or fistula.
