Read Full Paperexternally

Key Points

To examine the effect of bariatric surgery on the risk of upper gastrointestinal cancers, including oesophageal, liver, and gallbladder cancers.
Conducted a meta-analysis of existing studies on bariatric surgery outcomes.
Evaluated cancer risk associated with different types of bariatric surgical procedures.
Assessed the impact on weight management and cancer prevention.
Bariatric surgery is linked to a reduced risk of oesophageal cancer.
Liver cancer risk decreases following bariatric surgery.
Gallbladder cancer risk is also lower after bariatric procedures.

Abstract

Bariatric surgery appears to reduce the risk of oesophageal, liver, and gallbladder cancers, supporting a role in both weight management and cancer prevention. Standardization in reporting surgical procedures is needed to clarify effects by bariatric surgery type.
