Obesity is a chronic disease that predisposes to many complications like type 2 diabetes, cardiovascular pathologies, and cancer [1]. Bariatric surgery (BS) is nowadays the most effective treatment for morbid obesity. It allows a long-term body weight loss between 13 and 27%, depending on the surgery technique, and it reduces obesity mortality by 5% [2]. However, nutritional complications can occur after BS. Protein malnutrition is one of the most severe ones. Its incidence varies between 0 and 13% after Roux-en-Y gastric bypass (RYGBP) [3]. Prevention is essentially based on regular postoperative follow-up. When dietary management remains insufficient, the use of artificial nutrition (AN) may be necessary. AN after BS is poorly documented. Our objective was to analyze data of patients requiring AN after BS in an academic hospital. Methods
