减肥手术是有效的，在实现体重减轻严重肥胖，与大多数程序进行腹腔镜。短期术前能量限制饮食被广泛采用，以通过减小肝脏大小和改善肝脏灵活性来实现手术。然而，饮食方法没有标准化。这项观察性研究报告了英国各减肥服务机构使用的术前限制性饮食。2012年9月至11月期间，从减肥服务机构收集了当前或过去术前饮食的信息，以及任何为使用或修改饮食提供证据的研究。英国约三分之一的减肥服务机构（28）做出了回应，目前使用的饮食共计49种。饮食类型包括低能量、低碳水化合物和液体，59%提供低能量/低碳水化合物食物，21%提供牛奶/酸奶，18%提供代餐（液体），2%提供透明液体。饮食持续时间为7至42天。评估术前饮食及其替代方法的服务提供了有限的轶事证据，饮食选择主要由临床医生主导，这项研究突出了不同中心使用的减肥手术前饮食形式的差异性和缺乏共识。对替代饮食的结果进行比较的进一步研究将支持未来的最佳实践。
Bariatric surgery is effective at achieving weight loss in the severely obese, with the majority of procedures performed laparoscopically. A short-term pre-operative energy restrictive diet is widely adopted to enable surgery by reducing liver size and improving liver flexibility. However, the dietary approach is not standardised. This observational study reports on pre-operative restrictive diets in use across bariatric services in the UK.Between September and November 2012, information was collected from bariatric services on current or past pre-operative diets, and any research providing evidence for the use or modification of their diets.Around one third of bariatric services (28) in the UK responded, with a total of 49 diets in current use. Types of diet include low energy, low carbohydrate and liquid, with 59 % offering low energy/low carbohydrate food-based, 21 % milk/yoghurt, 18 % meal replacement (liquid) and 2 % clear liquid. Diet duration varies between 7 and 42 days. Limited anecdotal evidence was provided by services evaluating the pre-operative diet, and its alternative approaches, with dietary choice primarily clinician-led.This study has highlighted variability and lack of consensus in the form of pre-bariatric surgery diet used across different centres. Further research comparing outcomes for alternative diets would support best practice in the future.
