Acute liver injury and acute liver failure following bariatric surgery

Bariatric surgery is the most effective treatment for obesity and improves several manifestations of the metabolic syndrome, including nonalcoholic fatty liver disease. Strict nutritional counseling after bariatric surgery is a key in realizing these outcomes. When postoperative nutrient intake or nutrient uptake is compromised, bariatric surgery can also lead to severe hepatic complications. Here, we describe 3 cases of acute liver injury and acute liver failure caused by bariatric surgery, all with different management strategies and outcomes.
