Summary
Brief summary (as posted)
The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.

- Endoscopic Metabolic and Bariatric Therapies
- description
- Subjects who have had endoscopic bariatric therapies for obesity - primary and revision. Bariatric endoscopic procedures include ablation techniques, intragastric balloons, submucosal tunneling procedures (PSAM, GEM, G-POEM), tissue plication platforms (POSE, ROSE), endoluminal sleeves and endoscopic suturing devices (ESG).
