Tube Stomach Operation - Sleeve Gastrectomy

Tube Stomach Operation - Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is the most commonly used method in obesity treatment. It is when the stomach takes the form of a tubular tube that runs along the small curvature. Stomach volume is 150-200 cc on average.

The weight loss mechanism is in two ways in this surgery as a restrictive and hormonal effect. The feeling of satiety with less food as a result of narrowing the stomach longitudinally is a limiting effect. As a hormonal effect, there is a loss of appetite due to the decrease in the secretion of the ghrelin hormone produced from the cells in the fundus, which is the upper part of the stomach.

After the operation, patients lose 65-70% of their excess weight in approximately 12 months. The patient can increase this weight loss rate up to 100% with sports or other supporting factors.

One of the biggest advantages of sleeve gastrectomy operation is that there is no problem in vitamin and mineral intake since there is no procedure that affects absorption. Patients only receive temporary supplements such as iron during certain periods (first fluid feeding period).

As in all bariatric surgeries, nutrition changes gradually in this procedure, and cooperation should be made with the nutrition consultant during the adaptation period.

Surgery Summary

  • Tube stomach surgery is an operation performed under general anaesthesia.
  • Gastric sleeve surgery is performed by closed, ie laparoscopic methods. It can be made from a single hole or 4-5 holes or even with a robot, depending on the surgeon and patient. Since the holes are very small, they do not cause any future problems in terms of aesthetics.
  • In order not to make a mistake and reduce the stomach too much during the operation, a calibration tube is placed in the stomach inlet equal to the diameter of the oesophagus. Thanks to this calibration tube, while the stomach is reduced as if it is the continuation of the oesophagus, excessive stenosis and obstruction are prevented.
  • After the measures regarding vascularization and bleeding are taken, the stomach is cut to length with special cutting and covering tools (stapling).
  • After the procedure is completed, the calibration tube placed at the beginning of the operation is removed.
  • During the operation, one or more different techniques are used to test whether there is a leak or not. Similar tests can be done after surgery.
