Obesity Surgery (2022)CAbstract


The duodenal switch is the most effective bariatric surgical procedure. Due to technical demands of the surgery and concerns regarding high rates of post-operative nutritional sequelae, many surgeons remain hesitant to adopt this technique.


Sixty-five patients undergoing duodenal switch surgery at our hospital between 2008 and 2015 were followed up for 5 years. All patients were provided with a thorough post-operative nutritional supplementation regimen. Nutritional deficiencies as evidenced by blood testing, excess body weight loss, and remission rates from type 2 diabetes, hypertension, and dyslipidaemia were studied.


The average excess body weight loss 5 years post-operatively was 62% ± 23.03%. Remission rates for type 2 diabetes, hypertension, and dyslipidaemia were 96%, 77% and 84% respectively. Patients achieved good nutritional outcomes. After 5 years, deficiencies in fat-soluble vitamins A and D occurred in 3.3% and 1.6% of patients respectively. The rate of ferritin deficiency at the 5-year post-operative mark was 19.4%. No predictors of nutritional deficiency were identified on univariate analysis.


Patients undergoing a duodenal switch achieve good long-term excess body weight loss and high obesity-related co-morbidity remission rates. The rates of post-operative nutritional deficiencies in patients who are subjected to a thorough post-operative nutritional supplementation regimen are lower than what was historically expected.
