Weight Loss Surgery - Surgical Options
The three weight loss surgery options at Southern Maine Medical Center are:
Roux-en-Y Gastric Bypass
The Roux-en-Y gastric bypass is one of the most popular and successful surgical options for long term weight loss in the morbidly obese in the United States. It is a restrictive and malabsorptive procedure.
A portion of the stomach is divided off creating a small pouch for reduced food intake. The new pouch only holds about an ounce of food or less. This causes a feeling of fullness just after eating a few bites or restriction.
The small intestine is brought up and sewn to the pouch. Because most of the stomach and small intestine has been bypassed, this allows less calories and nutrients to be absorbed or malabsorbed.
Laparoscopic Gastric Banding
A band is placed around the upper portion of the stomach. This band separates the stomach into a smaller upper pouch without disrupting the normal digestion and absorption of calories and nutrients is unchanged. It is strictly restrictive.
The amount of food consumed can be adjusted with tightening or loosening the band. Most patients feel fuller faster with small amounts of food.
Laparoscopic Sleeve Gastrectomy
The third procedure offered at SMMC is the Sleeve Gastrecomy. As the name describes, a portion of the stomach is permanently removed, leaving a small tube or "sleeve" that will hold only a little bit of food. This will make you feel full more quickly and less hungry after meals.
Normal digestion and absorption is unchanged. This procedure is not reversible. This procedure may also be used as a staged procedure; a first step to gastric bypass for patient’s that are severely morbidly obese for initial weight loss.
Weight Loss Following Surgery
Surgery alone will not remove the excess pounds and keep them off. It is only a tool. To reach a healthy weight, patient’s must adjust their eating habits and exercise patterns. The greatest weight loss usually occurs in the first year to 18 months following the Rou-en-Y surgery with 50 to 75 percent loss in excess body weight and greatest weight loss in 2 to 3 years for the Lap band with 45 to 60 percent loss of excess weight. Southern Maine Medical Center has had excellent results from surgeries performed with high patient satisfaction rates.
