Prediction Model for Inadequate Weight Loss After Sleeve Gastrectomy

Prediction Model for Inadequate Weight Loss After Sleeve Gastrectomy

This study aims to develop and validate a prediction model for estimating the probability of inadequate weight loss one year after sleeve gastrectomy.

Inadequate weight loss (IWL) is a major problem after sleeve gastrectomy, leading to the recurrence of obesity-related comorbidities and increased risk of revision surgery. It is important to identify the high-risk individuals for IWL before surgery so that clinicians can initiate more rigorous weight monitoring and management strategies. Therefore, this study aims to develop a prediction model using preoperative clinical and laboratory data to estimate the risk of IWL one year after sleeve gastrectomy, and then validate it using two separate datasets.

Inclusion Criteria:

• BMI ≥ 27.5 kg/m2;
• 16 years ≤ age ≤ 70 years;
• Complete preoperative data and one-year follow-up information

Exclusion Criteria:

• Patients who did not undergo SG;
• Incomplete follow-up information;
• Patients with a history of pituitary or thyroid disease;
• Female patients who conceived within one year after surgery
