Endoscopic Sleeve Gastroplasty

What Is an Endoscopic Sleeve Gastroplasty?

The Endoscopic Sleeve Gastroplasty is a type of weight-loss procedure in which the stomach size is reduced by using an endoscopic suturing device, without the need for surgery or removal of part of your stomach. This procedure is recommended if you are overweight and other methods of weight loss such as dieting and exercise have been unsuccessful.

At King’s we offer the Endoscopic Sleeve Gastroplasty procedure as part of our Weight Loss & Bariatric Programme, whereby you have the option of continuous support for 6 months post surgery, to ensure you have the best opportunity to reach your weight loss goals.


Why Is the Surgery Done?

Being overweight brings along a large list of related health problems. Endoscopic Sleeve Gastroplasty is performed to help you lose weight and to reduce the impact of those conditions.

Who Is the Surgery Recommended For?

Endoscopic Sleeve Gastroplasty is mostly recommended for people who are clinically diagnosed as obese, but your doctor might decide if the procedure is beneficial for you or not. The following conditions are normally required to qualify for the procedure:

  • BMI above 30.
  • No eating disorder history.
  • Blood sugar under control.
  • No history of stomach ulcers.
  • Have attempted weight-loss through diet and exercise without success.

For select candidates, the ESG procedure can be done even if a previous weight loss surgery has been performed.

Benefits and Potential Results

Endoscopic sleeve gastroplasty can lead to significant weight loss, depending on how much you change your lifestyle habits. Recent studies have shown that depending on BMI some patients lose approximately 17Kg in the first six months.  Also, the following conditions can be improved:

  • Diabetes
  • Hypertension
  • Hyperlipidemia
  • Heart diseases
  • Sleep apnea
  • Osteoarticular diseases


Early studies have shown a favorable safety profile. Usually, patients experience pain and nausea that can be managed and disappear after 2-3 days.

Before Surgery

In order to be selected as a valid candidate for the procedure, your doctor might require some lab tests and also, will recommend a high-protein and low-carbohydrate diet some days before. The night before, you are not allowed to consume any food or liquid after midnight.

During Surgery

Endoscopic sleeve gastroplasty is a non-invasive procedure that can be done using an endoscope, a flexible tube with a camera, and a suturing device. The procedure involves the following steps:

  • The endoscope passes through your mouth into your stomach.
  • There will be placed some sutures in your stomach, in order to restructure it into a tube shape, reducing the stomach size.
  • After the procedure, you will be monitored closely for any complication.

As a result, you will feel full sooner, restricting the number of calories your body absorbs. General anesthesia is required and the whole procedure will take about half an hour.

After Surgery

Immediately after the procedure, you won’t be allowed to eat or drink for about 8 hours. After that, a liquid diet will be required for two weeks. Around week four, you will be allowed to move into semi-solid foods, and eventually to your regular healthy diet. Most people go home within the same day and it takes about 1-3 days to fully recover at home and return to work.
