Laparoscopic Sleeve Gastrectomy Overview

Laparoscopic Sleeve Gastrectomy surgery (VSG) is one of the newer bariatric operations. It can be performed as a stand-alone procedure for those who have relatively less weight to lose, who are older, or who are at higher risk for more extensive surgeries. It can also be part of a staged operation, converting to a Duodenal Switch or Roux-en-Y Gastric Bypass for additional weight loss. Weight loss rates average 55-70% of excess body weight, and can be even higher for those who are otherwise healthy, relatively young and able to exercise.

Laparoscopic Sleeve Gastrectomy is the only bariatric procedure involves no malabsorption (difficulty absorbing nutrients common in other procedures) or foreign body issues (introduction of an internal device such as a Lap Band). Because of the simplicity of the operation, there is also a very low risk of requiring additional surgery in the future.

Weight loss is restrictive and takes place because the stomach is reduced to about 60cc in volume (compared to 1,000 to 2,000cc for a normal stomach). Patients feel full after a very small amount of food, are satisfied with less and, as a result, lose weight. Hunger also diminishes because the body has a reduced capacity to produce ghrelin, a naturally occurring hormone that induces a feeling of hunger.

VSG preserves the pylorus, a valve that regulates the emptying of the stomach. The result is a more normal feeling of fullness as food slowly trickles out. When food quickly empties out of the stomach it can result in complications known as dumping and marginal ulcers, which are more common with other procedures. Symptoms include nausea and diarrhea.

Before the Procedure

  • Stop smoking and begin eating 5-6 small meals per day.
  • Consider joining a Wellstar support group for bariatric patients.
  • Your medical history will be reviewed. Medical tests may include a urinalysis, glucose test for diabetes, thyroid analysis, chest x-ray, electrocardiogram and psychiatric evaluation.
  • Begin an exercise program to increase your fitness and stamina.
  • You will receive counseling on nutrition and fitness to help you modify your habits and maximize post-surgery results.
  • Tell your doctor about all medications or supplements you take. You may need to discontinue those that can increase bleeding.

During the Procedure

  • You will be given an anesthetic to put you to sleep for the surgery.
  • Your Wellstar surgeon will make 5 small incisions in your belly. A tiny video camera (laparoscope) and thin surgical instruments will be inserted through the incisions.
  • While viewing your belly on a video screen, the surgeon will remove the left side of your stomach, leaving a much smaller “sleeve-shaped” stomach.
  • The procedure takes about an hour, depending on a patient’s previous operations.

After the Procedure

  • You will be monitored in a recovery room and will be required to stay one night in the hospital.
  • A nurse or therapist will help you get up and walk soon after your surgery to keep your blood moving and improve healing.
  • You will be able to return to work and normal activities, including strenuous activity, after about two of weeks.
  • You may have a catheter in your bladder to remove urine.
  • You will wear special stockings that help prevent blood clots.
  • You may not be able to eat immediately after surgery, but will soon be able to have liquids, then pureed and soft foods. You will find that you become full after a small meal.
  • The sleeve gastrectomy is not a quick fix for weight loss. Your doctor will talk with you about ongoing diet and exercise to maximize your results.
  • You will see your Wellstar bariatric surgeon regularly to monitor your progress and address any possible complications.
  • You will need to take extra vitamins and supplements to stay healthy.
