LAPAROSCOPIC SLEEVE GASTRECTOMY
SLEEVE WEIGHT LOSS SURGERY
PROCEDURE, ADVANTAGES & RESULTS
About Laparoscopic Sleeve Gastrectomy Surgery
The sleeve gastrectomy has its roots in the earliest gastroplasty and anti-reflux procedures. This procedure generates weight loss primarily through gastric restriction (reduced stomach volume). The stomach is restricted by stapling and dividing it vertically. After surgery the stomach volume is reduced to approximately 1/3 of its original volume. The stomach that remains is shaped like a banana and holds between 50 to 150 mL (about 2 to 5 ounces). The nerves to the stomach and the outlet valve (pylorus) remain intact with the idea of preserving the function of the stomach while drastically reducing its volume.
The Minimally Invasive or Laparoscopic Approach
A small camera is passed through a port into the abdomen so the surgeon can view the operative site on a nearby video monitor. Delicate instruments are used to perform the operation through five tiny incisions. The laparoscopic approach to surgery has many advantages including reduced post-operative pain, shortened hospital stay, quicker recovery, and better cosmetic results.
Weight Loss after Sleeve Gastrectomy
Typically people who have sleeve gastrectomy surgery lose 55% or more of their excess body weight within the first year. Studies have shown that after sleeve gastrectomy people show improvement in diabetes, high blood pressure, high cholesterol and sleep apnea within one to two years (see benefits of weight loss surgery). These improvements are comparable to those seen after other weight loss procedures.
Advantages of Sleeve Gastrectomy Surgery
• Laparoscopic approach
• No intestinal re-routing
• Reduces stomach capacity and allows the stomach to function normally so most food items can be consumed, in small amounts.
• Eliminates the portion of the stomach that produces the hormones that stimulates hunger (Ghrelin).
• Dumping syndrome is avoided.
• Minimizes the risk of an ulcer forming.
• Reduces the risk of intestinal obstruction (blockage), marginal ulcers, anemia, osteoporosis, protein deficiency and vitamin deficiency.
• Appealing option for people who are concerned about the risks of intestinal bypass procedures.
• Appealing option for people who are concerned about having an implanted medical device.
• Small incisions and minimal scarring
Diet and Exercise After Weight Loss Surgery
Weight loss gives you more energy, makes you feel better about yourself and motivates you to continue the changes that have made you successful. The success of any weight loss operation must begin with realistic goals; once established, your motivation will ultimately determine the amount of weight you lose. Weight loss surgery works with you, not by itself. It creates a situation where a small amount of food makes you full and less hungry, reducing the number of calories eaten in a day. If you take advantage of this situation, you will lose weight.
Exercise adds to this by increasing the number of calories burned. When you exercise, you build muscle, which increases your metabolic rate, which burns more calories. We strongly encourage the addition of exercise to weight loss surgery, as the combination of eating fewer calories and burning more calories is very powerful for successful weight loss.
There are patients who go through the trouble of having weight loss surgery and do not lose much weight because they expect the surgery to do the work for them. Becoming a thinner person requires change. You must be more active and make wise food choices. An example is a patient who eats a large quantity of high-calorie liquids such as milkshakes or sugary sweets. Sugar is an unnecessary source of calories that you must burn off with exercise. We strongly recommend not eating sweets after weight loss surgery (unless it’s your birthday). Try sugar-free foods. Other patients sabotage their success by grazing or emotional eating -- eating small amounts of food throughout the day. After weight loss surgery, if you avoid sugar, high-calorie liquids and emotional grazing, you will increase your success rate. The best way to lose weight is to eat less and exercise more.
Northwest Weight Loss Surgery has developed a comprehensive after care program to better prepare you for the lifelong changes after surgery. We encourage you to attend our monthly support groups where we discuss many topics relating to the weight loss journey. For patient success stories click here.
Motivation is the Key to Weight Loss
Most patients who've had weight loss surgery found it to be the only thing that allowed them to keep the weight off long-term. We hear people say things like "weight loss surgery gave me my life back” and "I wish I would have done this sooner”. We have many successful patients, but it is incorrect to think that you do not have to put any effort into losing weight. Your surgeon will educate you on your responsibilities as a weight loss surgery patient. These include new eating patterns and a new lifestyle.
