What this trial studies

This study aims to identify predictors for gastroesophageal reflux disease (GERD) following sleeve gastrectomy. Participants will undergo an upper endoscopy with the EndoFLIP device before the surgery to gather data on various parameters. A follow-up endoscopy will be conducted at six months post-surgery if clinically indicated, along with questionnaires over a five-year period to assess outcomes. The goal is to develop a predictive model for GERD after the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years with a BMI of 30 or greater who can consent to the procedure.

Not a fit: Patients with severe esophagitis, Barrett's esophagus, major motility disorders, or previous stomach surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at risk for GERD after sleeve gastrectomy, leading to better management and outcomes.

How similar studies have performed: Other studies have explored similar predictive models for post-surgical complications, indicating potential for success in this approach.
