What is the difference between gastric bypass, stomach stapling and gastric band?

Degrees: Band: appliance surg inserted to cinch stomach; adv.-easier surgery, reversible; disadv-less wt loss, less sustained, higher failure rate, compl, slippage, etc. Stapling-surg restrictive procedure; adv: more sustained, succ. Than above; disadv-still easy to cheat/wt gain (e.g. Melt ice cream, then drink it). Bypass: combo restrict and malabsorp; adv: more effective; dis: bigger op, more nutr risk.

Many differences: The band is a device goes over top part of the stomach. Bypass makes your stomach the size of a golf ball and detours your small bowel to increase weight loss. Stomach stapling or the vertical banded gastroplasty is not done anymore. Although some people are starting to call the new sleeve gastrectomy stomach stapling as well.
