What this trial studies
This is an observational follow-up of patients who underwent bariatric procedures five or more years ago to document long-term outcomes such as sustained weight loss, comorbidity status, complications, and quality of life. Clinical records, anthropometric measures, and patient-reported information will be collected at participating centers and analyzed to identify predictors of durable success or failure. The project aims to compare outcomes across different surgical techniques and patient profiles to inform surgical decision-making. Findings will be used to develop criteria for personalized surgical planning and targeted follow-up.
Who should consider this trial
Good fit: Adults who underwent bariatric surgery at least five years ago and are able to provide informed consent and attend follow-up at the participating centers are ideal candidates.
Not a fit: People who had bariatric surgery less than five years ago, are unable to consent, or cannot participate in follow-up visits are unlikely to benefit from this project.
Why it matters
Potential benefit: If successful, the results could help clinicians choose the most appropriate operation for each patient and tailor follow-up to reduce long-term weight regain and complications.
How similar studies have performed: Prior cohort and registry studies have suggested some predictors of long-term outcomes after bariatric surgery, but results are inconsistent and no clear consensus exists.
