Gastroplasty means changing the volume or shape of the stomach (or both). In endoscopic gastroplasty (ESG), both the shape and volume of the stomach are changed by folding the inner wall of the stomach. ESG is a simple operation that can be described as being a non-surgical procedure, as one does not need to make a surgical incision on the patient’s body.

The procedure itself is performed by inserting the endoscope through the mouth and down into the stomach, where the stomach is then sewn together from the inside. No tissue will be cut or removed at any time during the procedure, which significantly reduces the risk of subsequent complications. After the procedure, the stomach will typically be reduced by 40-50% compared to the original size.

The benefits of a stomach reduction are greatest in people with a BMI between 30-40 and where the necessary lifestyle changes have been a challenge. In other words, ESG will provide you with the necessary prerequisite for you to start losing weight.

How is the procedure performed?

ESG is performed under general anesthesia – also called general anesthesia. Although performed as an outpatient treatment, general anesthesia is necessary to perform this procedure.

The surgeon inserts the endoscope and the advanced wire device through the mouth to reach the abdomen. Using an advanced thread technique, the surgeon “folds” the inner layers of the stomach using the endoscope, which is then subsequently sewn with a special overlock technique. This results in a significant reduction in the volume of the stomach – typically up to 40-50% compared to the original size.

Unlike the traditional form of surgery, in which the surgeon enters through the skin, this type of procedure does not leave any surgical scars. The small perforations that occur in the inner layers of the stomach when the folds are sewn together have a very short healing time, compared to the more traditional methods.

After the procedure

After undergoing ESG, it is very important to drink plenty of fluids and solid foods should be avoided for the subsequent 10-14 days.

Since the procedure is outpatient, you will be discharged the same day. However, it is expected that you will feel stabbing pain in the first days after a procedure, and the associated doctor will therefore prescribe pain medication for you.

Vitamins and other supplements are needed in the first time after the procedure. In some cases, however, it will be necessary to continue vitamin and dietary supplements for an extended period of time.
