Dr. Chiasson has had a longstanding interest in performing therapeutic endo-bariatric weight loss procedures.  The U.S. Food and Drug Administration’s (FDA) recent authorization of the “Apollo ESGTM System” to perform Endoscopic Sleeve Gastroplasty (ESG) is a very important development.  He is excited to be one of the first surgeons in the Southwest to offer this procedure in his practice. Located in Tucson, AZ.

What is the Endoscopic Sleeve Gastroplasty?

Endoscopic Sleeve Gastroplasty is an “Incisionless” weight loss procedure involving a small suturing device attached to the end of a GI endoscope. The endoscopist uses the suturing device to reduce and shorten the size of the patient’s stomach by 70-75%.  The procedure involves no incisions or scars and does not remove any of the stomach.


Who is a candidate for Endoscopic Sleeve Gastroplasty?

The Endoscopic Sleeve Gastroplasty procedure using the Apollo ESG System has been approved by the FDA for individuals with a BMI from 30-50.  This procedure is also indicated for those patients of Middle Eastern, Asian, or East Indian descent with a BMI of 27 due to their increased risk of Metabolic Disease.


How does the Endoscopic Sleeve Gastroplasty work?

Endoscopic Sleeve Gastroplasty works by limiting the amount of food that one can eat at one time.  In addition, the new anatomy associated with the procedure results in food passing more slowly into the small intestine.  This results in the patient feeling full for a longer period of time despite eating much less.


What should you expect after Endoscopic Sleeve Gastroplasty?

The Sleeve Gastrectomy is generally performed as an outpatient procedure. The procedure is performed under general anesthesia and generally takes about one hour.  I use the latest pain and nausea control techniques to avoid these symptoms following the procedure.  In general, the majority of patients experience minimal discomfort and nausea after the procedure.  Most are able to return to their normal activities within a few days.  At this time, this procedure is not covered by insurance.


Advantages of the Endoscopic Sleeve Gastroplasty?

Endoscopic Sleeve Gastroplasty is a safe, non-surgical weight loss procedure.  In addition to significant weight loss, the procedure has been demonstrated to have a significant impact on the associated medical conditions associated with obesity and metabolic disease such as high blood pressure, Fatty Liver, and Type II Diabetes.  It has the least nutritional risk of all the permanent weight loss operations.  Finally, if necessary, this procedure can be revised or converted to a more aggressive surgical weight loss procedure.


How much weight loss is associated with Endoscopic Sleeve Gastroplasty?

Endoscopic Sleeve Gastroplasty has been extensively evaluated.  On average, patients who have this procedure will lose about 20% of their total body weight.
