For those considering gastric bypass surgery, take a look at Amazon's do-it-yourself kit. It's only $260 (cheap!) and comes with 3 sets (so you don't have to get it right the first time!). Bring your own anesthetics and instructions, though.
You wouldn't believe HALF the weird shit that comes through the doors of an emergency room every single day.
That's why I don't work in a public hospital anymore. To many crazy, mean, know-it-all jerks come crying to the emergency room when they try some wacka-doo self-surgery procedure. Self-surgery is just ONE of the things in the 'weird shit' category an ER nurse sees on a daily basis.
Yes, sadly...super sadly...people try doing this stuff without trained surgeon(s) and medical team.
