Not able to recruit enough patients

The purpose of this research study is to understand the mechanism of weight loss for weight loss procedures: that is Laparoscopic sleeve gastrectomy and Endoscopic sleeve Gastroplasty.

We want to better understand the mechanisms for weight loss by understanding the anatomic and physiologic changes that occur with gastric restrictive procedures for weight loss and to determine the differences in metabolic profile between the two restrictive procedures. We also want to identify the rate of Gastro Esophageal Reflux Disease (GERD) in patients undergoing gastric restrictive procedures for weight loss.

Inclusion Criteria:

1. BMI ≥ 30 Kg/m2 scheduled to undergo a bariatric intervention
2. Patients who will be undergoing ESG or LSG as part of their clinical care Age between 18 and 75 years.
3. Both male and female subjects will be included in the study.
4. Subjects from any ethnic background will be included in the study.
5. Female participants of childbearing age should not be pregnant. (Pregnancy test will be performed on all women of child bearing potential before any standard of care endoscopic procedure. For the purpose of the study we will record that information in the patient study records).
6. Successfully complete the screening process.
7. Patients able to provide written informed consent on the IRB/EC-approved informed consent form.
8. Demonstrate willingness to follow protocol requirements, including follow-up schedule, and completion of questionnaires.
