Background: Bariatric surgery (BS) results in major and sustained weight loss and improves comorbidities in patients with obesity but can also lead to malnutrition, especially through severe malabsorption and/or surgical complications. Little is known about the efficacy of artificial nutrition (AN) in this setting. Methods: In this case series, we describe data from consecutive severely malnourished patients after BS (resectional and non-resectional), managed by AN at our hospital unit over a 4-year period. Results: Between January 2018 and June 2022, 18 patients (mean ± SD age 42.2 ± 10.4 years, 94% women) required AN following BS complications. At the time of AN initiation, more than half of the patients (53%) had multiple revisional surgeries (up to four). Mean BMI was 49.7 ± 11.3 kg/m2 before BS and 29.6 ± 9.6 kg/m2 when AN was initiated. Most patients (n=16, 90%) received enteral nutrition. AN management resulted in weight regain (+4.7kg ± 8.0, p=0.034), increased serum albumin (+28%, p=0.02), pre-albumin (+88%, p=0.002), and handgrip strength (+38%, p=0.078). No major AN complication nor death was observed. Median total AN duration was 4.5 months [1-12]. During follow-up, the cumulative duration of hospitalization was 33 days [4-88] with a median of 2.5 hospitalizations [1-8] per patient. Conclusion: Malnutrition can occur after any BS procedure, and AN when required in this setting appears safe and effective on nutritional parameters. It is important to recognize the potential risk factors for malnutrition, which include excessive weight loss resulting from surgical complications, eating disorders, multiple revisional BS, and pregnancy.
