Bariatric surgery for obesity and metabolic conditions in adults

This week's British Medical Journal examines evidence related to the safety, efficacy, and metabolic outcomes of bariatric surgery to guide clinical decision making.

Drs David Arterburn and Anita Courcoulas summarized recent evidence related to the safety, efficacy, and metabolic outcomes of bariatric surgery to guide clinical decision making.

Several short term randomized controlled trials have demonstrated the effectiveness of bariatric procedures for inducing weight loss and initial remission of type 2 diabetes.

Observational studies have linked bariatric procedures with long term improvements in body weight, type 2 diabetes, survival, cardiovascular events, incident cancer, and quality of life.

Perioperative mortality for the average patient is low
British Medical Journal

The team found that perioperative mortality for the average patient is low but varies greatly across subgroups.

The incidence of major complications after surgery also varies widely, and emerging data show that some procedures are associated with a greater risk of substance misuse disorders, suicide, and nutritional deficiencies.

The team reported that more research is needed to enable long term outcomes to be compared across various procedures and subpopulations, and to identify those most likely to benefit from surgical intervention.

Dr Arterburn's team concludes, "Given uncertainties about the balance between the risks and benefits of bariatric surgery in the long term, the decision to undergo surgery should be based on a high quality shared decision making process."
