Using imaging to predict weight loss success after bariatric surgery

Radiomics of Intra-abdominal and Subcutaneous Adipose Tissue Predict the Efficacy of Bariatric Surgery (RISABS)

Observational China-Japan Friendship Hospital · NCT06169033

This study is testing if looking at CT scans of belly fat can help predict how much weight people will lose and if their type 2 diabetes will improve after bariatric surgery.

What this trial studies

This study aims to analyze abdominal CT scans of patients scheduled for bariatric surgery to extract radiomic features from intra-abdominal and subcutaneous fat. By combining these imaging data with clinical characteristics, the researchers will develop a predictive model to assess the potential weight loss and remission of type 2 diabetes mellitus at 1, 3, and 5 years post-surgery. The observational nature of the study allows for a comprehensive understanding of how these factors correlate with surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates include individuals with a BMI greater than 27.5 kg/m2 who have type 2 diabetes and are planning to undergo bariatric surgery.

Not a fit: Patients who do not have an abdominal CT scan or who are not undergoing sleeve gastrectomy or Roux-en-Y gastric bypass may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients who are more likely to benefit from bariatric surgery, leading to improved treatment outcomes.

How similar studies have performed: While the use of radiomics in predicting surgical outcomes is an emerging field, similar studies have shown promise in other areas of medicine, suggesting potential for success in this approach.
