E-news: Risks and benefits of bariatric surgery - all the recent evidence

This review by Arterburn and Courcoulas summarises all the recent evidence relating to the safety, effectiveness and metabolic outcomes of bariatric surgery.

Its aim is to guide clinical dicision making. It seeks to assess which patient groups may benefit most from the different types of surgical intervention and, indeed, which individuals may be 'cured' of such conditions as T2DM, balanced against the potential harmful risks of undertaking major surgery in a sub-optimally fit populaton group. 

Added to this is the emerging evidence that some procedures are adversely associated with a higher risk of substance misuse disorders (perhaps replacing one addiction for another), suicide and nutritional deficiencies. 

The authors conclude that, give the wide variation in outcomes, any decision to undergo surgery should be based on a high quality shared decision-making process.
