Sleeve Gastrectomy

Selected obesity treatments and their medical experts and clinics in Switzerland – Ticino.

Bariatric surgery is not indicated for cosmetic reasons. A gastric bypass is used in patients who suffer from a very high BMI (> 35). A gastric bypass limits food intake and restricts the amount of calories and nutrients the body absorbs.

Advantages

  • Patients who suffer from morbid obesity have an extremely high risk of being affected by the following pathologies:
  • Hypertension
  • Diabetes
  • Heart diseases
  • Strokes
  • Arthrosis and degenerative joint diseases
  • Sleep apnea
  • Men: colorectal and prostate cancer
  • women: uterus, breast and gallbladder cancer
  • Lower life expectancy

Sleeve-gastrectomy promotes the loss of most of the excessive weight and also prevents the occurrence of the the above mentioned diseases.

Compared to the gastric bypass, sleeve gastrectomy is less complicated but more mutilating, having the same amount of complications. It’s a relatively recent surgery with not much long term experience.

Indications

The eligible patients are those who suffer from obesity (BMI 35 kg/m2) that couldn’t lose weight or maintain weight loss despite medical treatment (diets, drugs or nutritional advices).

What is the Body Mass Index (BMI) ?

Body Mass Index can be calculated dividing the weight in kilogram by the square meter height. The result indicates if a person has a normal weight (BMI from 18 to 24.9 kg/m2), is overweight (BMI from 25 to 29.9kg/m2) or obese (BMI from 30 to 39.9 kg/m2). The morbid obesity has a BMI of  beyond 40kg/m2.

Contraindications

Bariatric surgery is not indicated for cosmetic reasons.

Procedure

What to expect

Sleeve-gastrectomy is not a minor surgery. For this reason bariatric surgery can be performed only in centers certified by Swiss Study Group for Morbid Obesity (www.smob.ch).

Preparation

The first medical examinations with our specialists will determine if you have to undergo a bariatric surgery. If there are no contraindications you will have to meet further specialist for preoperative analyses. These specialists will follow you during the postoperative period.

The preoperative tests are the following:

  • A gastroscopy
  • A cardiological evaluation (ECG, blood pressure, plus other tests if necessary), a pulmonary function evaluation (spirometry) and further evaluations to rule out any condition concerning obesity and metabolic diseaeses.
  • A psychiatric evaluation

Treatment plan

The minimally invasive surgery is performed under general anaesthesia: about 80-85% of  the stomach is removed and a gastric tube of 2 cm diameter is packed.

Duration

The length of stay is about 5-7 days.

Recovery

After a Sleeve-gastrectomy vitamine, iron or mineral salts malabsorption can occur, leading to deficiency syndromes. These blood values need to be controlled, at first at shirt-term intervals, then annually for the rest of life.

Recommended behavior after treatment or therapy

After a Sleeve-gastrectomy your diet must be changed and regulated. You must be very careful to what you’re going to eat: enough proteins, few fats, avoid sugars. Vitamines and mineral salts must be intaken regularly.

Risks & complications

The surgical complications will be explained by the specialist.
