Obesity Surgery

Bariatric surgery is the only permanent method for treatment of people who have Body Mass Index > 40 or > 35 with comorbidities. Bariatric surgery is an important alternative for people who cannot lose weight, since it increases quality of life and prolongs life expectancy. Since complication rate is very low and intended weight is rapidly accomplished, bariatric surgery is ever increasingly preferred. It is performed by surgeons, who are well experienced in this field, in Istanbul Cerrahi Hospital, after appropriate patient is carefully selected.

Bariatric Surgery Methods in Istanbul Cerrahi Hospital;

  • Gastric Balloon
  • Gastric Bypass
  • Sleeve Gastrectomy
  • Gastric Bypass

In Gastric Bypass, a large portion of stomach is bypassed and a small volume of stomach is prepped and anastomosed to small intestines.

As it is also the case for other bariatric surgery operations, this type of surgery aims that some part of nutrients is discharged without being absorbed by decreasing volume of stomach and inactivating a part of small intestines. Therefore, patient can be satiated with less food.

Similar to other bariatric surgery operations, gastric bypass is performed with laparoscopic method. Surgery is carried out through small abdominal incisions. Therefore, patient can be largely protected against possible risks, including without limitation wound infection and herniation.

In post-operative period, patients can easily feel satiety with a small serving of food. Later, this satiety turns into loss of appetite. General food intake significantly decreases.

Surgeon and dietician should properly plan necessary vitamin and mineral supplementations due to small size of stomach and decreased food absorption. Therefore, patient can lose weight without resultant vitamin and mineral deficiencies. In Istanbul Cerrahi Hospital, patients can be discharged three or four days after the surgery.

Sleeve Gastrectomy :

Vertical Sleeve Gastrectomy or Vertical Gastrectomy implies removing out 75% of stomach on vertical plane and converting shape of stomach into a tube or “banana”. Procedure is laparoscopically performed with stapler.

Laparoscopic Sleeve Gastrectomy (LSG) is an effective surgical procedure for patients with high body mass index and at high risk for safe weight loss.

Sleeve Gastrectomy is a new bariatric surgery technique, which can be laparoscopically performed to decrease gastric volume. Stomach is transformed into configuration of a tube, which appears like continuum of esophagus. Patients can be satiated when patients eat only ¼ of foods they used to eat, since volume of stomach is decreased by 75%. Since intestine is not bypassed in this method, malabsorption is not observed and less food intake causes weight loss.

Sleeve Gastrectomy emerged as a method that restricts food intake. However, metabolic effects are observed due to altered hormonal homeostasis.

Sleeve Gastrectomy is ever increasing used in last couple of years. A substantial part of stomach is irreversibly removed in sleeve gastrectomy. Volume of rest stomach measures approximately 150 to 200 ml.

Sleeve Gastrectomy poses two effects on obesity:

  1. Patient can be easily satiated, since gastric volume is decreased.
  2. Since large amount of appetite hormones are synthesized in stomach, loss of appetite and regression in feeling of hunger between meals are noted.
