Using imaging to predict weight loss success after bariatric surgery

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

Run by China-Japan Friendship Hospital · NCT06169033 · Data updated 2026-11-12

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.

Is this trial a fit for you?

Likely a 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.

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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 gone: 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.
