Gastric Bypass v. Duodenal Switch

Hello! I am nearly approved for the Gastric Bypass surgery, but I've been wondering if the Duodenal Switch might be the better option for me. I qualify - My BMI is around 51. I've heard that the duodenal switch is much more effective, but also much more risky. I do want to have children a few years down the road as well, so that factors into my decision. Does anyone have any input that might help me out? Thanks!!

I'm doing the switch on the 27th with Dr. Marchesini. My research went from lap-band to RNY to DS. Over-all I liked the prospect of maintaining the pyloric valve. The DS board really helped me, if you like re-post there. Best wishes on your ultimate decision! -Cam
