Minimally Invasive Approaches to Weight Loss Surgery
The surgeon makes several very small abdominal incisions to insert a tiny camera and surgical instruments in to the abdomen to complete the surgical procedure.
Laparoscopic Roux-en-Y Gastric Bypass
The surgeon creates a small stomach pouch using staples, then attaches a section of the small intestine directly to the newly created pouch. The small stomach pouch restricts the amount of food consumed, while the rerouting of the intestine allows food to bypass a portion of the small intestine where calories and some nutrients are usually absorbed. This is both a restrictive and malabsorptive procedure. The volume of food consumed at any one time is limited, and there is further calorie reduction due to decreased absorption.
Laparoscopic Sleeve Gastrectomy
A thin, vertical “sleeve” of stomach is created using a stapling device. The newly created sleeve is roughly the size of a banana. The remaining unused portion of the stomach is completely removed from the body.
This is a restrictive procedure, meaning that the volume of food consumed at any one time is limited.
Laparoscopic Adjustable Gastric Band
A silicone band is placed around the uppermost part of the stomach, creating a smaller stomach pouch. A connecting tube and filling port are placed in the soft tissue under the skin. Over time, the band will be slowly filled with sterile water to create a feeling of early fullness when eating.
This is a restrictive procedure, limiting the volume of food passing through the banded portion of the upper stomach at any one time.
Revision Bariatric Surgery
Under certain circumstances, a previous bariatric surgical procedure may have failed due to technical or behavioral reasons, causing weight regain. A second bariatric surgery procedure may be considered to facilitate weight loss.
Revision bariatric surgery carries a much higher risk for surgical complications, and the potential for any meaningful weight loss may be much less. Each situation is very unique, and must be thoroughly evaluated on an individual basis.
