Sleeve Gastrectomy (Gastric Sleeve)

Pre-Operations Tests

Before the procedure, radiologic scanning tests, blood and hormonal tests might be demanded.

Operation Details

The vertical sleeve gastrectomy, also known as the sleeve gastrectomy or gastric sleeve, restricts the amount of food you eat by reducing the size of the stomach. The minimally invasive procedure removes a great portion of the stomach (%70-80), making the stomach roughly the size and shape of a banana. This involves making five or six small incisions in the abdomen and performing the procedure using a video camera (laparoscope) and long instruments that are placed through these small incisions. Weight loss is achieved through 2 mechanisms in this procedure.

  • Restrictive Effect: Weight loss associated with a mechanical limitation and reduced of gastric mobility as a result of gastric volume reduction.
  • Endocrine Effect: Sense of satiety is achieved by ensuring reduction of levels of ghrelin hormone, defined as hunger hormone, produced by the portion of the stomach removed. Ghrelin is a peptide protein secreted by the cell in upper portion of the stomach fundus. It strongly stimulates the region in the brain that increases appetite. During sleeve gastrectomy operation, fundus region which produces ghrelin of the stomach is removed so appetite is reduced, contributing to weight loss.

Patients who have had a sleeve gastrectomy can develop reflux or heartburn symptoms in the first few weeks but this usually settles quickly.

Patients who have had a hiatus hernia operation cannot have this surgery.

Operation time, Hospitalization and Total Stay in Country

Operation time of this procedure is 2-3 hours. 4 days hospitalization is required for this procedure.  The patient can start to eat 8 hours after the operation. After the discharge, the patient should stay for 7 days in the country for doctor controls.


  • 50 to 60% extra weight loss within the first 6 months of the procedure.
  • Dumping syndrome is minimized because the pylorus is preserved.
  • Minimizes the chance of an ulcer occurring.
  • A great deal of health improvements in medical condition; especially diabetes type 2, high blood pressure, high cholesterol and obstructive sleep apnea.
  • Stomach functions are normally allowing and most foods are to be eaten in small amounts.
  • The procedure is simpler than gastric bypass operation.
  • It is the most recommended surgery method for the patients who are suitable.
