Abstract
This study aims to understand the prevalent practices on the nutritional aspects of the enhanced recovery after surgery (ERAS) protocol based on the knowledge and practice of surgeons, nutritionists, and anesthesiologists who work in the bariatric and metabolic surgery (BMS) units worldwide. This cross-sectional study enrolled BMS unit professionals from five continents-Africa, America, Asia, Europe, and Oceania. An electronic questionnaire developed by the researchers was provided to evaluate practices about the three nutritional aspects of ERAS protocol in BMS (Thorel et al. 2016): preoperative fasting, carbohydrate loading, and early postoperative nutrition. Only surgeons, nutritionists, and anesthesiologists were invited to participate. One hundred twenty-five professionals answered the questionnaires: 50.4% from America and 39.2% from Europe. The profile of participating professionals was bariatric surgeons 70.2%, nutritionists 26.4%, and anesthesiologists 3.3%. Approximately 47.9% of professionals work in private services, for about 11 to 20years (48.7%). In all continents, a large majority were aware of the protocol. Professionals from the African continent reported having implemented the ERAS bariatric protocol 4.0 ± 0years ago. It is worth mentioning that professionals from the five continents implemented the ERAS protocol based on the published literature (p= 0.012). About preoperative fasting abbreviation protocol, a significant difference was found between continents and consequently between services (p= 0.000). There is no uniformity in the conduct of shortening of fasting in the preoperative period and the immediate postoperative period. Early postoperative (PO) period protein supplementation is not performed in a standard fashion in all units globally. ERAS principles and practices are partial and insufficiently implemented on the five continents despite the prevalent knowledge of professionals based on evidence. Moreover, there is no uniformity in fasting, immediate postoperative diet, and early protein supplementation practices globally.
