Sleeve gastrectomy, also called a vertical sleeve gastrectomy, is a well known and most popular surgical weight-loss procedure. This procedure is typically performed laparoscopically using surgical devices called “staplers”.Laparoscopy is a minimal invasive surgery using an endoscope pass through the abdomen. Minimal invasive surgery means less risk to the patient.
Sleeve gastrectomy, also called a vertical sleeve gastrectomy, is a surgical weight-loss procedure. This procedure as mentioned above is performed laparoscopically through several small abdominal incisions.
Vertical sleeve gastrectomy is a procedure thet reduces stomach size via partial gastrectomy that preserves the lesser curve and pylorus. The patient’s stomach is removed about 75-80 percent of its original size resulting in a sleeve or a tube-like structure like a banana reducing the volume of the stomach to 150-200 ml, consequently limiting food intake. Although sleeve gastrectomy appears to be a purely restrictive procedure, its mechanism of action is more complex. As a result small size of stomach after the surgery causes patients to feel satiated sooner and reduces the secretion of ghrelin also called hunger inducing(orexigenic) hormone. Thus, the patient does not feel hungry, and he/she gets full so quickly because of the reduced size of stomach.
The patients lose about 80 % of the excess body weight in the first year after sleeve gastrectomy. However, the stomach volume may increase in the following years.
There is the risk of not being able to lose adequate amount of weight and even regain weight when diet and exercise rules and bariatric eating habits are broken and former bad habits such as sweet tooth and binge eating are resumed because of the interruption of psychiatric treatment. That’s why the patients undergoing sleeve gastrectomy should be followed-up closely as recommended by bariatric team
Diet after sleeve gastrectomy:
Patients will have a special diet after gastric sleeve operation. This type of diet will be prepared and followed up by our dietitians and the patient will has to obey the rules for 3 weeks. Then, it is followed by mash food period, allowing the patient to eat pureed meals after 3rd week and then to start eating solid foods after 4th week. Patients can have their normal dieting after 4th week but have to eat small amounts of food because of the reduced size of stomach.
Some advantages of sleeve gastrectomy are listed below:
- Less postoperative pain
- Less blood loss and scarring
- Reduce patient risks and accelerates recovery
- Not change the natural anatomy of the digestive system, thus does not lead to mineral or vitamin deficiencies,digestion and absorption functions continue normally after sleeve gastrectomy.
- Not cause Dumping syndrome
- No foreign body in the abdominal cavity such as adjustable gastric band
Some disadvantages of sleeve gastrectomy are listed below:
Risk of bleeding (0,1%) and leakage (0,1%) according to relatively longer staple line and high intraluminal pressure due to lack of anastomosis between the stomach and small bowel.

The success rate after gastric sleeve surgery increases depending on strict postoperative controls and observations. Therefore, your first visit will be done 7 days after surgery for early complications.
Your routine controls will be done in the 1st-3rd-6th-12th-18th-24th-36th-48th-60th
postoperative months. Fasting blood sugar and insulin levels, liver enzymes, vitamins and mineral levels as well as renal functions will be checked through blood tests. Supportive treatments will be started if any deficiencies found. Our dietitian will also follow up your body composition.
If you have severe metabolic conditions such as uncontrolled diabetes, your follow up will be done by our endocrinologist. You can send your test results if you are living abroad via whatsapp and face-to-face communication with our team with video conferences.
