Bariatric surgery has been performed for decades. For most of those years, surgeons performed bariatric surgery using an open technique, which required a long incision and traditional medical instruments.
As medical technology evolved, the laparoscopic or minimally invasive technique was introduced and widely adopted. Using the minimally invasive technique, a surgeon performs the same operation, but creates six half to one centimeter incisions and uses long-handled instruments. This technique is associated with faster recovery, less pain, and less scarring.
The most popular operations being performed today are laparoscopic, gastric bypass, sleeve gastrectomy and laparoscopic adjustable gastric banding.
Laparoscopic and open gastric bypass have similar success rates in reducing excess weight and improving or resolving co-morbid conditions.
