ESG – Benefits

The major benefit of the ESG is that it is performed endoscopically with a stitching device placed into the stomach through the mouth. This means that unlike surgery, there is no cutting or stapling, no scarring and no wounds. The procedure is carried out by pioneering surgeon Mr Jamie Kelly, in Southampton, under general anaesthetic and usually takes about an hour.

It works by reducing stomach capacity and slowing down the speed at which food passes into the bowel. The food you eat goes into a small pocket at the top of the stomach before working its way down through the reduced, banana shaped stomach, and emptying into the bowel.

Weight loss with the ESG

Since we did the UK’s first ESG procedure in 2016 we’ve been monitoring results, both our own and those of the other world leading centres that offer it.

We’ve been delighted with the outcomes and we’ve seen some spectacular success stories.

Our own weight loss results* have seen most patients losing over half of their excess weight within 2 years. Some have done much better than this and lost all of their excess weight.

As with all weight loss procedures there is a small proportion (about 10-20%) for whom the procedure is unsuccessful and for whom it is best to consider a surgical procedure.

As the ESG continues to grow in popularity across the world so do the number of publications that show its outcomes.

Based on these studies an accurate indication of weight loss would be that after 2 years most people can expect to have lost 15-20% of their starting weight. Most of this weight loss is achieved in the first year

Although these weight loss outcomes are a little lower than we would expect from the surgical sleeve and bypass they are comparable to those for gastric band. Most importantly, they are sufficient to achieve a major improvement in health and life expectancy.

Studies also show that the rate of complications with ESG is low too. One study showed the post-operative complication rate to be as low as 2.4% (AlQuatani et al December 2018).

Here is a summary of published weight loss data:

ParticipantsAvg weight loss at 2 years
Alqahtani et al160015-20%
Lopez-Nava et al24818.6%
Sharaiha et al9120.9%

In the Lopez Nava study we saw that nearly all of the weight loss was achieved in the first 6 months

Other benefits of the ESG

Aside from the weight loss it delivers, the main benefit of ESG is that it’s not surgery, so patients benefit from a faster recovery time and lower post-operative risks, both incidence rate and severity.

We are therefore expecting the ESG to grow rapidly in popularity and for the number of procedures we do to increase accordingly.

Health benefits of the ESG

Through losing weight ESG patients will enjoy the same benefits that accrue from weight loss with any procedure, including improvements in:

  • Diabetes
  • Hypertension
  • Sleep apnoea
  • Back pain and arthritis
  • Self esteem

Similar to the gastric band, health improvements will come steadily over time as you lose weight. The sleeve and bypass procedures are a little different because they offer immediate health improvements by changing the anatomy of the stomach. If you are managing existing health issues associated with your weight, the sleeve or bypass are options you should consider as well as the ESG.

More about weight loss with the ESG

The evidence we have suggests people can expect to lose about half of their excess weight over a 12-18 month period*. At this stage, because this is still a new procedure, longer term weight loss results are not available.

The weight loss results in the chart below are the published results from a study of 248 ESG patients. They show average total body weight loss (TBWL) as a percentage of the starting weight. We’ve also shown how much weight this equates to assuming different starting weights.

In summary, based on the published data you can expect to lose just over half of your excess weight after 24 months after your procedure. This is similar to the weight loss with a gastric band and a little below the weight loss we’d expect with a surgical sleeve or gastric bypass.
