Endoscopic Sleeve Gastroplasty FAQ

Learn about the Endoscopic Sleeve Gastroplasty (ESG) and if it’s the right procedure to help you reach your weight loss goals.

What is the Endoscopic Sleeve Gastroplasty (ESG)?

The Endoscopic Sleeve Gastroplasty (ESG) is a new weight loss procedure done by endoscopy where a flexible device called an endoscope with a high-definition camera is introduced into the patient’s mouth throughout the esophagus until it reaches the stomach. Once in the stomach, the surgeon will apply stitches to it by using an attached endoscopic suturing machine, significantly reducing the stomach’s size and volume by 50% or more.

There are no incisions or cuts and the stomach will not be cut or bypassed. The procedure is done under general anesthesia and lasts around 30 to 50 minutes (the procedure itself) plus the anesthesia induction and recovery time.

How much does this procedure cost?

See our pricing page.

Who can have this procedure?

Qualifications for this surgery should be discussed with one of our coordinators. Please contact us to see if you qualify.

Exceptionally, and under individual evaluation it can be used in very high BMI to bridge the patient to a safer BMI to have surgery or in patients with conditions that prevent surgery. 

How does the pre-op diet / preparation differ from other surgeries?

The pre-op diet and preparation is shorter and less restrictive consisting of 24 hours of liquid diet, two weeks of protein pump inhibitors (Like Omeprazole), and 8 hours fasting on the day prior to the procedure.

The use of blood thinners, compression socks, and other medications or measures follow specific guidelines and will be informed individually.

What should I expect on the day of the procedure?

You will spend one night in the hospital. Some mild pain and nausea are expected and last around 6 to 18 hours but you will be on medication. When discharged, the patient will go to the EOC hotel to complete the recovery. Full recovery is expected in one week, but patients can safely travel in 3-4 days.

How does the post-op diet differ from the other surgeries?

You will follow the same post-op diet we recommend for all weight loss surgery options.

How much weight loss should I expect?

The results we achieve with our patients show a loss of around 15 to 20% of the total weight that can be translated into around 50-60% loss of excess weight.

As with any other weight loss procedures, there are responders and not responders. In one of our studies, we show a responder rate of 84% in the two-year follow-up. A recent publication had also shown less weight loss but non-inferiority when compared to sleeve gastrectomy up to three years follow-up.

Is Endoscopic Sleeve Gastroplasty a surgery?

Yes. Though less invasive than a traditional incision based surgery, it is surgery via the mouth without incision or cutting the stomach.

How long has this surgery been performed?

Dr. Manoel Galvao and other pioneers of Endoscopic Gastroplasty started performing it in 2012. The endoscopic suture itself has been in use since 2010.

What are the complications?

Endoscopic procedures are even less invasive than laparoscopic procedures with less number of complications. The overall complication rate among all studies published ranges around 2 to 2.5%. In EOC, our own publications show less than 1%.

Any procedures that involve suture can have bleeding and perforations but these complications are rare and can most of the time be solved by endoscopy itself and in even rarer cases by laparoscopy.
