Gastric Sleeve Surgery

The Laparoscopic Gastric Sleeve Surgery

Our partner doctors recommend gastric sleeve surgery for people with a BMI higher than 35 and also underline that this procedure offers significant advantages over other surgical options. The effect of weight reduction is significant and starts immediately after surgery. Already in between three and six months, patients usually lose 25 kgs to 50 kgs, depending on their weight before the operation.

In about 80% of patients who have undergone gastric sleeve surgery, there is a decrease in the accompanying diseases such as hypertension, diabetes, insuline resistance, cardiac problems etc. whereupon a further treatment of medication is no longer necessary.

After the operation, long-term success in maintaining the ideal weight is highly observed. However, in some cases patients might gain back weight. This situation should be assesed by the performing surgeon for a possible “re-sleeve”. This might be possible at any time as well as the possibility of a conversion to a special gastric bypass is still present. This possibility of revision procedures also makes the gastric sleeve mostly the first choice among all other surgical options.

The surgery itself takes between 45 to 90 minutes. Shortly after the procedure, the patients are transferred to the patients´ station after the recovery phase, they are then allowed to have a certain amount of liquid and are already mobilized on the same day of the surgery.

The fluid intake is expected to return to normal within two days, so that most patients will more likely to be able to leave the hospital as early as on the third day after the surgery and are suitable to travel after the next day. The gastric sleeve surgery is performed using a minimally invasive technique and it is mostly performed with the key-hole method(laparoscopic). Generally 3 or 4 trocars with a diameter of 5 – 12 mm are inserted through the abdominal wall into the abdominal area. Subsequently, the stomach is seperated from the surrounding tissues and the %80 of the gastric pouch is removed. The remaining pouch is sutured and closed in the longitudinal direction by special titanium staples.

In doing so, the pylorus remains intact. The excess portion of the stomach is removed from the places accessed by the abdominal wall. In this way, the gastric capacity is limited to about 100 ml – 150 ml. The tubular conversion and reduction of the stomach leads to the fact that even small amounts of food already lead to an effective and mostly persistent feeling of satisfaction.
