Endoscopic Gastroplasty vs Gastric Sleeve: When Does Each One Work?

In recent years, endoscopic gastroplasty has emerged as a "non-surgical" alternative for patients with overweight or grade I obesity seeking to lose weight without a major surgical intervention. But is it really comparable to gastric sleeve? Dr. César Hernández Elenes in Mexicali analyzes the differences so you make an informed decision.

What is endoscopic gastroplasty?

Endoscopic gastroplasty is a minimally invasive procedure where, through the mouth (endoscopically), internal sutures are placed that fold the stomach to reduce its capacity by approximately 70%. There are no external incisions, no tissue is removed and it is theoretically reversible. It is performed under general anesthesia but does not require prolonged hospitalization.

What is gastric sleeve?

Gastric sleeve is a laparoscopic surgery that definitively removes 80% of the stomach. 4-5 small incisions are made in the abdomen, the stomach is sectioned and stapled, and the removed portion is extracted. It is a definitive procedure with documented long-term results.

Differences in effectiveness

Endoscopic gastroplasty produces a loss of 15-20% of body weight in the first year. Gastric sleeve produces a loss of 25-30% of body weight (60-70% of excess weight) in 12-18 months. The difference is significant: the sleeve nearly doubles the results of endoscopic gastroplasty. This is because the sleeve permanently removes tissue and reduces ghrelin production, while gastroplasty only folds the stomach without eliminating hunger hormone-producing cells.

Result durability

5-year studies show that endoscopic gastroplasty maintains approximately 60% of initial loss, with gradual re-stretching of the stomach and potential need for "endoscopic revision" in some patients. Gastric sleeve maintains 70-80% of initial loss at 5-10 years in patients who maintain healthy habits.

Recovery and times

Endoscopic gastroplasty has very fast recovery: return to normal activities in 3-5 days, no visible scars, no risk of wound infections. Gastric sleeve requires 2-4 weeks of recovery, leaves 4-5 small scars of 5-10 mm, and has risks inherent to laparoscopic surgery (bleeding, leak, infection) although in certified centers they are less than 2%.

Who is each procedure for?

Endoscopic gastroplasty is appropriate for patients with BMI 30-35 (grade I obesity) without severe comorbidities, or overweight patients (BMI 27-30) who do not qualify for formal bariatric surgery. Gastric sleeve is the procedure of choice for patients with BMI 35-45 (or BMI 30-35 with comorbidities such as type 2 diabetes, hypertension or sleep apnea). For BMI >45, bypass or duodenal switch are usually considered.

Economic considerations

Endoscopic gastroplasty has an intermediate cost: lower than gastric sleeve but higher than intragastric balloon. If insufficient results lead to subsequently requiring a gastric sleeve, the total cost can be higher. Gastric sleeve is a one-time investment with more lasting results, which also reduces medications for diabetes and hypertension, generating long-term savings.

Recommendation

If your BMI is between 30-35 and you seek a non-surgical procedure with moderate results, endoscopic gastroplasty may be suitable. If your BMI is greater than 35, you have comorbidities, or you seek the best possible long-term results, gastric sleeve remains the reference procedure. In consultation with Dr. César Hernández, your complete profile is evaluated to recommend the most effective option for your particular case.
