What is Endoscopic Sleeve Gastroplasty (ESG)?

ESG is a minimally invasive weight-loss procedure using an endoscope, a flexible tube with a camera, and an endoscopic suturing device attached. Using the endoscope, your surgeon places sutures in the stomach to change the structure of your stomach. Shaping the stomach into a tube restricts the amount of food you can eat because you feel fuller sooner. 

It helps you lose weight by limiting how much you can eat. Like other weight-loss procedures, endoscopic sleeve gastroplasty requires being dedicated to maintaining a healthier lifestyle. You must make permanent healthy changes to your diet paired with regular exercise to help ensure the long-term success of ESG.

What is the Endoscopic Sleeve Gastroplasty (ESG) Process?

Before the Procedure

If you qualify for endoscopic sleeve gastroplasty, our team will give you specific instructions on how to prepare. The following are some of the most common preparations for ESG:

  • Various lab tests and exams before surgery
  • Restrictions on eating, drinking, and which medications you can take
  • Starting a physical activity program

You should also plan for recovery after the procedure, such as arranging for someone to help at home for a few days.

During the Procedure

Endoscopic sleeve gastroplasty is an outpatient procedure using general anesthesia, so you'll be unconscious. The procedure is performed orally with no incisions and generally takes up to ninety minutes.

ESG uses an endoscope, a flexible tube with a camera, and an endoscopic suturing device attached. Your surgeon places sutures in the stomach to change the structure of your stomach. ESG reduces the size of the stomach by 70-80%. Shaping the stomach into a tube restricts the amount of food you can eat. Food stays in the stomach for a longer time, allowing patients to feel fuller.

This procedure does not remove any part of the stomach. Because the procedure is minimally invasive by going through the mouth and avoiding incisions, it reduces the risk of operative complications and allows for a quick return to daily activities.

After the Procedure

Most ESG patients return home the same day after recovering from sedation. However, some patients might require a short hospital stay for observation, generally no more than one day and night.

After the procedure, you won't be allowed to eat for a few hours. When you are released to eat, you will start a liquid diet lasting at least two weeks. After those two weeks, you can move on to semisolid foods before beginning a regular, healthy diet.
