What is gastric sleeve surgery?
Sleeve gastrectomy is a surgical procedure that transforms the stomach into a tube. An examination of the digestive system shows that almost all organs in this system are tubular. The esophagus and intestines are all organs in the form of elongated tubes. The stomach, which is an exception in this system, is shaped like a sack rather than a tube so that it can hold more food and create storage. Sleeve gastrectomy is an operation in which a large portion of the stomach is irreversibly removed and converted into a system that continues the esophagus and intestines. No tube or other foreign body is inserted into the stomach. Because the shape of the stomach resembles the shape of a tube, it is known as gastric sleeve surgery.
The only effect of the treatment is not to reduce stomach volume. Since the stomach shrinks into a tubular shape, this also has a strong effect on the hunger hormone released by the stomach. The need for food decreases, the brain feels less hungry, so gastrointestinal operations are not only mechanical but also hormonal.
WHICH DISEASES ARE USED for gastric sleeve surgery?
Sleeve stomach surgery is primarily used to treat pathological obesity. Many diseases associated with morbid obesity, including type 2 diabetes, benefit greatly from this surgical treatment. However, group bypass surgery is more successful when the primary target is type 2 diabetes rather than obesity.
In addition, gastric sleeve surgery can be used as a transitional operation for patients with severe obesity. Gastric sleeve surgery can be used to prepare very obese patients for group bypass surgery.
HOW IS gastric sleeve surgery performed?
- Sleeve stomach surgery is an operation that is performed under general anesthesia.
- The operation is almost always performed with closed, i.e. laparoscopic, methods. Depending on the surgeon and patient, this can be done from a single hole or through 4-5 holes or even with a robot. Since the holes are very small, it will not cause any problems in terms of aesthetics in the future.
- In order not to make a mistake during the operation and not to make the stomach too small, a calibration tube with the diameter of the esophagus is placed at the stomach entrance. Thanks to this calibration probe, the stomach is made smaller like a continuation of the esophagus, preventing excessive stenosis and obstruction.
- After taking precautions regarding vascularity and bleeding, the stomach is cut from length to length with special cutting and closing tools (staples).
- After completing the procedure, the calibration tube placed at the beginning of the operation is removed.
- One or more different techniques are used during surgery to test for leaks. Similar tests can be done after surgery.
