Laparoscopic Vertical Sleeve Gastrectomy

About

A sleeve gastrectomy procedure is a purely restrictive weight loss surgery whereby part of the stomach is removed and a new smaller stomach is retained. There is no intestinal bypass associated with a sleeve gastrectomy. Most patients achieve successful, effective weight loss in a manner similar to the gastric bypass. Most patients can lose 75 to 80% of their excess body weight over 12-24 months with sleeve gastrectomy alone.

How it Works

Performed laparoscopically, a sleeve gastrectomy is a restrictive weight loss surgery in which up to 85% of the stomach is removed. The resulting or remaining stomach resembles a narrow tube. The function of the stomach remains in tact, however there is a dramatic reduction in capacity for holding food, effectively reducing the amount of food one eats to feel satiated. The portion of the stomach producing the hunger stimulating hormone ghrelin is also removed, another factor contributing to remarkable weight loss.

Because the function of the stomach is preserved, there are relatively few food restrictions aside from a healthy diet. One of the greatest advantages of a sleeve gastrectomy is that there is no requirement for intestinal bypass, therefore decreasing any complications commonly associated with gastric bypass. A sleeve gastrectomy does not require adjustments to attain a proper level of restriction.

Advantages

Restrictive Procedure:

Restricts stomach capacity, leading to more prompt feelings of fullness with a decreased food intake. There is no malabsorption of calories associated with bypass.

Reduction of Hunger Stimulating Hormone:

The portion of the stomach that produces the hunger stimulating hormone Ghrelin is removed, thereby decreasing hunger and boosting weight loss.

Relief or resolution of obesity related health conditions:

A sleeve gastrectomy procedure can lead to significant health improvements including resolution or improvement of; type 2 diabetes, high blood pressure, heart disease, sleep apnea, acid reflux and cholesterol levels.

Laparoscopic Procedure:

Laparoscopic surgeries require smaller incisions than open surgeries and produces far less tissue trauma which ultimately reduces recovery periods and pain associated with recovery.

No Bypass of Intestinal Tract:

The normal function of the stomach is retained; patients do not suffer the complications associated with gastric bypass including “dumping syndrome.

No Implant or Foreign Body:

No long-term complications associated with the adjustable gastric band such as band slippage or erosion.

No Ongoing Vitamin or Mineral Supplementation Required:

Adequate nutrition may be obtained strictly from the diet.

Eligibility

The laparoscopic sleeve gastrectomy is an ideal weight loss surgery for individuals seeking a restrictive operation that does not require the maintenance of an adjustable gastric band and do not want the complications associated with intestinal re-routing. With commitment to a long-term health and lifestyle change, a sleeve gastrectomy procedure is an effective tool for weight loss. Generally patients who meet the criteria below may qualify for laparoscopic sleeve gastrectomy surgery.
  • You have a BMI of 30 for higher
  • You suffer from obesity related health conditions
  • You have attempted to lose weight in the past without success
  • You are mentally capable
  • You are free from alcohol or chemical dependency
  • You want low maintenance surgery, no band adjustments
  • You are apprehensive about the possible side effects of gastric bypass
  • You are apprehensive about a the possible side effects of a LAGB implant (band slippage or band erosion)
  • You have medical conditions that prevent you from having LAGB or bypass, such as anemia, Chron disease or other medical conditions
  • You are on anti-inflammatory medications that may cause ulcers for these patients gastric bypass is not recommended If your BMI 50, you may want to consider as part 1 of 2 part procedure

Some physicians may use the sleeve gastrectomy as a first of a two part procedure. This enables the patient to lose a substantial amount of weight before having a gastric bypass. Typically highly motivated patients do not require the second stage. Many patients choose a sleeve gastrectomy as a primary bariatric procedure. Speak to an AMBI representative about your eligibility.

Risks and Complications

Complications can be medical or specific to sleeve gastrectomy surgery. Medical complications can be those associated with anaesthesia and your general health and include; Bleeding, pain, shoulder pain, pneumonia, complications due to anesthesia and medications, deep vein thrombosis, injury to stomach, esophagus, or surrounding organs, infection, pulmonary embolism, stroke or heart attack and rarely death (0.3%).

Specific complications to sleeve gastrectomy include; blood clots in the deep leg veins, damage to adjacent organs, and leakage of digestive contents through the staple line. It is important you are well informed of potential risks and complications before you undergo surgery. Your surgeon will discuss these with you in advance of your surgery.
