Model to predict weight loss outcomes after sleeve gastrectomy

Prediction Model for Inadequate Weight Loss After Sleeve Gastrectomy

Observational China-Japan Friendship Hospital · NCT06157606

This study is trying to create a tool that helps doctors predict which patients might not lose enough weight after having sleeve gastrectomy, so they can provide better support before the surgery.

What this trial studies

This observational study aims to develop and validate a prediction model that estimates the likelihood of inadequate weight loss one year following sleeve gastrectomy. By analyzing preoperative clinical and laboratory data, the study seeks to identify individuals at high risk for inadequate weight loss, allowing for tailored preoperative management strategies. The model will be validated using two separate datasets to ensure its reliability and applicability in clinical settings.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 16 to 70 with a BMI of 27.5 kg/m2 or higher who are scheduled for sleeve gastrectomy.

Not a fit: Patients who have not undergone sleeve gastrectomy or those with incomplete follow-up information will not benefit from this study.

Why it matters

Potential benefit: If successful, this model could help clinicians better manage patients undergoing sleeve gastrectomy, potentially improving weight loss outcomes and reducing the risk of obesity-related complications.

How similar studies have performed: While prediction models for weight loss outcomes after bariatric surgery exist, this specific approach focusing on sleeve gastrectomy and its validation across multiple datasets is relatively novel.
