The vertical sleeve gastrectomy or known as longitudinal “vertical” gastrectomy, gastric reduction or vertical gastroplasy is a laparoscopic bariatric “weight loss” surgery aiming at reducing the stomach size by stapling the stomach and removing a part of it leaving a banana shaped sleeve or tube from the stomach. The operation is irreversible.
Laparoscopic Sleeve Gastrectomy is a Safe and Effective Weight Loss Surgery for High BMI and High Risk patients.
Sleeve Gastrectomy (LSG) is a new form of laparoscopic surgery that reduces the size of the stomach. The stomach is made smaller by stapling so that it takes the shape of a sleeve that will act as a new smaller stomach. The reduced size generates weight loss because less food can be eaten without any bypass of the intestines or malabsorption.
LSG (laparoscopic sleeve gastrectomy) has emerged as a restrictive operation, but its ability to extend beyond that through hormonal modifications raises a promise that it will play a leading role in the future of bariatric surgery, either as a sole operation or as part of a more extended procedure. 3
Sleeve Gastrectomy Surgery – a Brief Walk-through
- This vertical sleeve gastrectomy procedure is performed under general anesthesia and it requires only a small abdominal incision, or laparoscopic, to do stomach stapling and remove the separated part.
- Laparoscopic sleeve gastrectomy surgery implements staples in order to create a new stomach.
- Laparoscopic sleeve gastrectomy surgery reduces the size of the stomach up to 85%.
- The excess stomach volume is removed, not left in place.
Advantages of Laparoscopic Sleeve Gastrectomy
- A good single stage operation for weight reduction for moderately obese patients.
- Improvement in co-morbidities of obesity, such as hypertension and diabetes mellitus, has been reported to occur in the majority of patients with resolution in 60-100%. 1
- It does not require disconnecting or reconnecting intestines.
- The stomach is reduced but functions normally and almost every type of food can be consumed, though in small amounts.
- Many patients lose up to 60% of their excess body weight within six months of their Lap Sleeve Gastrectomy surgery.
- By removing most of the excess stomach volume, the Ghrelin hormone production is mostly eliminated and therefore the sensation of hunger is being reduced.
- It is a simpler surgery than RNY.
- There is no malabsorption as with RNY, minerals and vitamins are not necessary, this may be important though in older patients.
- There is no dumping syndrome but sugar substitutes may be better tolerated.
- No foreign device is inserted in the body (as in lap band or johnson & johnson band surgery).
- Can be converted into almost any other WLS (weight loss procedure).
Disadvantages of Laparoscopic Sleeve Gastrectomy:
Although it has promising effects, LSG operation has some disadvantages like:
- It is irreversible.
- Complications may develop due to the stapling procedure.

As any surgical procedure, there are some pre-operative preparations to fulfill carefully. The pre-operative preparatory instructions from your doctor will mainly include:
- Start Atkins diet for 2 weeks before the surgery to reduce the fat around your liver.
- Make sure to be on a regular intake of clear fluids 48 hours before surgery.
- You must cleanse your colon before surgery by taking magnesium citrate or Colyte.
- Stop any medication unless indicated and recommended by your doctor.
- Stop any herbal medication and over the counter medications for headache or allergy or other similar conditions 7 days before the surgery.
Post-operative lifestyle & Dietary modifications:
You will be instructed to change your diet and eating habits. Drink more water (about 8 cups of water per day) and increase this amount 10-20% if you are exercising. You MUST not drink water or fluids with solid food. Regarding your meals, the first couple of months will be the hardest times as you have to adapt to your new stomach size. You must chew food well and eat smaller amount of food within longer meal time (30-45 minutes for meal). You must stop eating once you feel full. You should have 3 meals per day but the most important thing is to reduce fats and carbohydrates and make the main nutrient of your diet protein.
Candidates for this Lap Sleeve Procedure will be patients with extremely high BMI (greater than 55), those with complicated surgical histories, concerned about deficiencies in vitamins (malabsorption) and nutrition as with RNY, patients who want to minimize the risk of WLS or for whom lap band and Johnson & Johnson band (gastric band) adjustments are not convenient or available. The Vertical Gastrectomy has proven to be quite safe and quite effective for individuals with a BMI in lower ranges.
