Endoscopic obesity therapies
Endoscopic obesity therapies
Endoscopic obesity therapies are minimally invasive, incision-free, weight-loss procedures performed via an endoscope down the throat. Designed for patients with a BMI of 30-40, common methods include intragastric balloons (temporary, space-occupying) and endoscopic sleeve gastroplasty (ESG) (suturing the stomach smaller). They offer faster recovery, lower risks, and reduce weight, often by 15-20%.
Key Types of Endoscopic Obesity Therapies
- Intragastric Balloon (IGB): A soft silicone balloon is placed in the stomach and filled with saline, reducing appetite by taking up space. It is temporary, usually remaining for six months.
- Endoscopic Sleeve Gastroplasty (ESG): A specialized endoscopic device stitches the stomach to create a smaller, tubular shape, restricting food intake. This procedure can reduce the stomach volume by up to 75-80%.
- Aspiration Therapy (AT): A tube is placed into the stomach to allow for the removal of a portion of stomach contents after meals.
- Endoscopic Gastric Botox Injections: A relatively newer technique attempting to slow gastric emptying to induce satiety.
Candidates for Endoscopic Procedures
Endoscopic therapy is generally indicated for individuals who meet the following criteria:
- Body mass index (BMI) of 30–40 kg/m
- Patients who have failed other lifestyle modification programs.
- Those seeking an alternative to traditional surgery.
- Individuals seeking to restart weight loss after a prior surgical procedure.
Benefits:
- No Surgical Scars: Performed through the mouth, resulting in no external cuts.
- Faster Recovery: Outpatient setting with minimal downtime, often returning to normal activities within a few days.
- Improvement in Comorbidities: Improves obesity-related illnesses such as type 2 diabetes, high blood pressure, and high cholesterol.
Risks and Side Effects:
- Side Effects: Nausea and vomiting are common, particularly with balloons, but usually subside quickly.
- Weight Regain: There is a possibility of weight regain if long-term lifestyle changes are not maintained.
- Minimal Risks: Minor risk of bleeding, infection, or gastric ulceration.
Comparison with Traditional Surgery
- Endoscopic procedures, or Endoscopic Bariatric Therapies (EBTs), generally offer a better safety profile and lower cost than traditional laparoscopic surgery, though they may lead to less overall, permanent weight loss compared to procedures like Roux-en-Y gastric bypass.
