The Sleeve Gastrectomy is a purely restrictive procedure, whereby it limits the amount of food that can be eaten at one time.
A gastric “sleeve” is created by removing 80% of the stomach. This limits the amount of food that can be eaten at one time. No changes are made to the remainder of the intestines which allows for normal digestion and absorption. Gherlin producing cells are reduced with the removal of a portion of the stomach thus diminishing the sensation of hunger. This is a non-reversible procedure and does not require implanting an artificial device in the abdomen.
Advantages of the Procedure:
- Patients can expect to loss 70% of their excess weight at the end of one year.
- Weight loss begins immediately.
- Diminished sensation of hunger – Patient often feel less hungry and state the desire to eat is reduced.
- Does not require implanting an artificial device in the abdomen.
- Does not require manipulation as with the adjustable gastric band.
Risks & Precautions:
- Leaks can occur and may be from staple lines or due to poor healing.
- Marginal ulcers – ulcers in the gastric sleeve that can bleed, perforate (create a hole in the gastric pouch) or heal and cause narrowing of the gastric sleeve.
- Strictures or narrowing of the gastric sleeve. This can occur due to scar tissue or ulcer disease.
- Obstructions can occur due to scar tissue or ulcer disease.
- Vitamin and mineral deficiency can occur therefore patients are encouraged to take vitamin supplementation. It is recommended that all patients have their vitamin levels checked at regular intervals.
- Hernias can develop in up to 10 to 20 percent of patients after any type of abdominal surgery.
- Gallstones can occur due to rapid weight loss.
- Intolerance to certain foods can occur. It is recommended that patients speak with the Registered Dieticians at the Bariatric Surgery Institute at The Medical Center of Plano if they are experiencing this.
- Stretching and enlargement of the gastric sleeve can occur over time. This can lead to weight gain.
- Weight gain can occur if patients do not comply with the appropriate dietary guidelines. It is recommended that all patients follow up at regular intervals during the first year and yearly thereafter with the staff at the Bariatric Surgery Institute at The Medical Center of Plano. The best prevention to weight gain is early identification of maladaptive behaviors and modifying them.
- Due to the nature of this procedure it is not reversible.
- It is considered “investigational” by many insurance plans.
