Special Issue Information

Dear Colleagues,

In recent years, bariatric surgery has become an effective and relatively safe treatment for individuals with severe obesity. The number of patients undergoing bariatric surgery is increasing dramatically. The American Society for Metabolic and Bariatric Surgery estimates that in 2020 there were 198,651 bariatric surgeries in the United States.

In these individuals, the risk of nutritional deficiencies (vitamin B12, vitamin D, iron, calcium, vitamin B1, and others) is high, due in part to the presence of malnutrition of certain micronutrients even before surgery. Over the years, the number of individuals at risk of suffering nutritional complications will increase.

The new edition of this Special Issue will focus on the current state of knowledge on the nutritional management of patients with obesity before and after surgery. New research papers and reviews are welcome for this Issue.

SI topics are:

Nutritional risk assessment in the medium and long term after surgery;
Perioperative nutritional, metabolic, and non-surgical support of patients undergoing bariatric surgery;
Pre-operative nutritional management of patients with morbid obesity;
Evaluation of the efficacy of different nutritional supplements tailored to the bariatric patient.

Best regards,
Dr. Mauro Lombardo
Guest Editor

Abstract

Obesity is a crucial health problem because it leads to several chronic diseases with an increased risk of mortality and it is very hard to reverse with conventional treatment including changes in lifestyle and pharmacotherapy. Bariatric surgery (BS), comprising a range of various surgical procedures that modify the digestive tract favouring weight loss, is considered the most effective medical intervention to counteract severe obesity, especially in the presence of metabolic comorbidities. The Enhanced Recovery After Bariatric Surgery (ERABS) protocols include a set of recommendations that can be applied before and after BS. The primary aim of ERABS protocols is to facilitate and expedite the recovery process while enhancing the overall effectiveness of bariatric procedures. ERABS protocols include indications about preoperative fasting as well as on how to feed the patient on the day of the intervention, and how to nourish and hydrate in the days after BS. This narrative review examines the application, the feasibility and the efficacy of ERABS protocols applied to the field of nutrition. We found that ERABS protocols, in particular not fasting the patient before the surgery, are often not correctly applied for reasons that are not evidence-based. Furthermore, we identified some gaps in the research about some practises that could be implemented in the presence of additional evidence. Full article
