Weight Loss Surgery Procedures
The Digestive Process
To better understand how weight loss surgery works, it is helpful to know how the normal digestive process works. As food moves along the digestive tract, special digestive juices and enzymes arrive at the right place at the right time to digest and absorb calories and nutrients. After we chew and swallow our food, it moves down the esophagus to the stomach, where strong acid and powerful enzymes continue the digestive process. The stomach can hold about three pints of food at one time.
Roux-en-Y Gastric Bypass (RYGB)
The Roux-en-Y Gastric Bypass Surgery continues to be considered the “gold standard” for bariatric surgery. RYGB is the most common type of bariatric surgery. In gastric bypass surgery, a small pouch is created and then connected to a shorter length of the small intestine. This procedure both restricts food intake and interferes with absorption, resulting in more consistent weight loss. It can be performed either as a traditional open procedure or through the minimally invasive laparoscopic procedure
Laparoscopic Adjustable Gastric Banding Surgery (LAGB)
Laparoscopic Adjustable Gastric Banding (LAGB) surgery controls the amount of food you consume with the insertion of a hollow silicone band that is placed around the top of the stomach. The band creates as small pouch and narrow passageway allowing food to slowly pass through. The band is adjusted after the surgery and as needed with weight loss. With LAGB surgery there is no permanent alterations to the stomach or digestive system and the band can be removed The LAGB patient can expect a reduced hospital stay of one to two days; in some instances there may be an increased stay if the surgery required an abdominal incision or complications occurred. Patients may resume normal activities in one to two weeks.
The surgeon can control the amount of saline in the band using a fine needle through the skin. The adherence to monthly appointments for band adjustments the first 6-12 months after surgery is very important to achieve optimal results. Once the band is adjusted properly, the duration between visits can be lengthened. The adjustments are made in the surgeon’s exam room and patients have minimal discomfort. Finally, should the band need to be removed, the stomach will return to its original form and function.
Vertical Sleeve Gastrectomy
The gastric sleeve, also known as vertical sleeve gastrectomy, is a restrictive type of weight loss surgery that permanently reduces the size of the stomach. It promotes weight loss by limiting food intake and reducing the sensation of hunger. With this procedure, 60-80% of the stomach along the greater curvature is removed, leaving only a tube or “sleeve” for the new stomach pouch that extends from the natural stomach opening to the natural stomach outlet. There is no intestinal rerouting or food malabsorption. This procedure may be converted to gastric bypass if necessary for additional weight loss or can be a stand-alone procedure.
The sleeve gastrectomy is used for selected patients who are not candidates for the band or gastric bypass due to severe medical conditions, extremely high BMI, or prior bowel surgery. In some patients, the sleeve is used as a first stage procedure to improve their medical condition prior to a second stage gastric bypass.
Laparoscopic gastric plication, also known as laparoscopic greater curvature plication, has recently emerged as a new bariatric procedure. Gastric plication does not involve gastric resection, intestinal bypass, or placement of a foreign body, and this could potentially provide a lower risk alternative that will appeal to patients and referring physicians. The operation involves mobilizing the greater curvature of the stomach similar to the dissection for a sleeve gastrectomy and infolding or imbricating the stomach to achieve gastric restriction. There are increasing numbers of gastric plication procedures being performed worldwide and this operation is being marketed as a new option for surgical weight loss by some practices.
