Gastric Sleeve Surgery

The Laparoscopic Gastric Sleeve Surgery

Our doctors recommend gastric sleeve surgeries for people with a BMI higher than 35 and argue that it offers significant advantages over other surgical operations. 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 the starting weight.

In about 80% of patients who have undergone gastric sleeve surgery, there is a decrease in accompanying diseases like hypertension or diabetes, whereupon a further treatment of medication is no longer necessary.

Long-term success in maintaining the weight can be noted. However, in case of a renewed increase, a second narrowing of the stomach (re-sleeves) is possible at any time as well as the possibility of a conversion to a special bypass.

The surgery itself lasts 45 to 90 minutes. As per procedure, the patients are transferred to the patients´ station after the recovery phase, allowed to have a certain amount of liquid and are already mobile again on the same day of the surgery.
The fluid intake is expected to return to normal within two days, so that most patients will be able to leave the hospital as early as on the third day after the surgery and are suitable to travel after another day. The gastric sleeve surgery is performed using a minimally invasive technique (laparoscopic). As a rule, 3-4 small sleeves (trocars) with a diameter of 5 – 12 mm are inserted through the abdominal wall into the abdominal area. Subsequently, the stomach is removed from the surrounding area to the extent that the stomach is narrowed and severed in the longitudinal direction by means of 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.
