Although widely applied, there is no consensus about the characteristics of the diets prescribed in the immediate preoperative period of bariatric surgery (BS). The objective of this study was to perform a survey on preoperative dietary management in BS centers.
This was a cross-sectional study with BS Brazilian centers. Only BS centers with certificate of excellence by Surgical Review Corporation were included. An electronic questionnaire was applied to assess details about the dietary management in the immediate preoperative period of BS.
Of the 15 centers invited, 80% (n = 12) answered the questionnaire. Preoperative weight loss was required to patients in all 12 centers. For 8.3% (n = 1), this request was applied to all patients; 91.7% (n = 11) of the centers requested weight loss in specific cases. Ten (83.3%) centers prescribed restrictive diets; none of these adopted a standard dietary protocol. The caloric value of the diets ranged from 800 to 2000 kcal/day. The duration of the diet ranged from 10 to 20 days in 40% (n = 4) of the centers and from 20 to 90 days in 60% (n = 6) of the centers. Dietary prescription was based on team consensus in 100% (n = 12) of the centers. In 33.3% (n = 4) of the centers, scientific evidence supporting dietary prescription was cited.
This study identified the frequent practice of requesting preoperative weight loss and the diversity of diets used in the immediate preoperative period by Brazilian BS centers. Future guideline proposal is needed on preoperative BS diets.
尽管已广泛应用，但关于减肥手术（BS）术前即刻规定饮食的特点尚无共识。本研究的目的是对BS中心的术前饮食管理进行一项调查。
这是一项针对巴西BS中心的横断面研究。仅纳入获得外科评审公司卓越认证的BS中心。应用电子问卷来评估BS术前即刻饮食管理的详细情况。
在受邀的15个中心中，80%（n = 12）回复了问卷。所有12个中心都要求患者术前减重。对于8.3%（n = 1）的中心，此要求适用于所有患者；91.7%（n = 11）的中心在特定情况下要求减重。10个（83.3%）中心规定了限制性饮食；这些中心均未采用标准饮食方案。饮食的热量值范围为每天800至2000千卡。40%（n = 4）的中心饮食持续时间为10至20天，60%（n = 6）的中心为20至90天。100%（n = 12）的中心饮食处方基于团队共识。33.3%（n = 4）的中心引用了支持饮食处方的科学证据。
本研究确定了巴西BS中心术前要求减重的常见做法以及术前即刻使用的饮食的多样性。需要针对BS术前饮食提出未来指南建议。
