Minimally invasive surgery — operating through small incisions in the abdominal wall — means less pain and scarring, fewer complications, quicker recovery time, and a faster return to normal activity than open surgery. There are several types of bariatric surgery.
Laparoscopic Gastric Bypass
Gastric bypass is a minimally invasive approach to weight loss surgery. It involves making a small stomach pouch connected to the small bowel so that food is rerouted around the majority of the stomach. This rerouting results in metabolic changes that help drive weight loss. Like all weight loss surgery procedures, it requires a long-term commitment to major lifestyle and diet changes. The majority of people who undergo gastric bypass experience no complications, losing an average of 70 percent of their excess weight within two years after the gastric bypass procedure. Most people also enjoy a significant improvement or complete resolution of their obesity-related conditions.
Sleeve Gastrectomy is a minimally invasive approach to weight loss surgery. With this procedure, the stomach is reduced to about 25% of its original size by surgically removing a portion of the stomach. The result is a sleeve or tube-like structure. The portion of the stomach that is removed has hormonal activity that prevents weight loss. Therefore, much like gastric bypass, it also creates metabolic changes that help drive weight loss. Sleeve gastrectomy patients tend to lose about 60-70% of their excess weight.
Laparoscopic Gastric Band
Lap Band© is a minimally invasive approach to weight loss surgery. The surgeon places the band around a portion of the stomach, which limits the amount of food one can eat by slowly tightening the band. While the band produces good results (approximately 50 percent excess weight loss in most cases), the results are more gradual and less dramatic than those achieved by the gastric bypass and sleeve gastrectomy procedures. Although Lap Band may have the lowest immediate complication rate, it seems to have the highest long-term complication rate when compared to other weight-loss surgeries.
