There is currently little evidence available on various aspects of Revisional Bariatric Surgery (RBS) and no published consensus amongst experts. The purpose of this study was to understand variation in practices concerning RBS.
Bariatric surgeons from around the world who perform RBS were invited to participate in a questionnaire-based survey on SurveyMonkey®.
A total of 460 respondents from 62 countries took the survey. For revision after gastric banding, Roux-en-Y gastric bypass (RYGB) (75.5%, n = 345) emerged as the commonest choice followed by sleeve gastrectomy (SG) (56.9%, n = 260) and one anastomosis gastric bypass (OAGB) (37.2%, n = 170). For revision after SG, RYGB (77.7%, n = 355) was the commonest option followed by OAGB (42.45%, n = 194) and re-sleeve (22.32%, n = 102). For revision after RYGB, surgical pouch reduction (49.1%, n = 223), prolongation of bilio-pancreatic limb (30.0%, n = 136), and surgical stoma size reduction (26.43%, n = 120) were the most preferred options. Approximately 90.0% of respondents (n = 406/454) routinely perform an upper gastrointestinal endoscopy before an RBS, and 85.6% (n = 388/453) routinely perform a contrast study. Ninety percent (n = 403/445) reported that the demand for RBS was usually patient-driven, and there was wide variation in criteria used to define successful response, non-responders, and significant weight regain.
This survey is the first attempt to understand various aspects of RBS. The findings will help in identifying areas for research and allow consensus building amongst experts.
目前，关于减重手术翻修术（RBS）的各个方面几乎没有可用的证据，专家之间也没有达成共识。本研究旨在了解 RBS 实践方面的差异。
邀请来自世界各地进行 RBS 的减重外科医生参与基于 SurveyMonkey®的问卷调查。
共有来自 62 个国家的 460 名受访者参与了这项调查。对于胃束带后进行的修正，Roux-en-Y 胃旁路术（RYGB）（75.5%，n=345）是最常见的选择，其次是袖状胃切除术（SG）（56.9%，n=260）和单吻合口胃旁路术（OAGB）（37.2%，n=170）。对于 SG 后进行的修正，RYGB（77.7%，n=355）是最常见的选择，其次是 OAGB（42.45%，n=194）和再袖状胃切除术（22.32%，n=102）。对于 RYGB 后进行的修正，手术胃囊缩小术（49.1%，n=223）、胆胰吻合延长术（30.0%，n=136）和手术吻合口缩小术（26.43%，n=120）是最受欢迎的选择。大约 90.0%的受访者（n=406/454）在进行 RBS 前常规进行上消化道内镜检查，85.6%（n=388/453）常规进行对比研究。90.0%（n=403/445）报告说，RBS 的需求通常是由患者驱动的，并且用于定义成功反应、无反应和显著体重复增的标准存在很大差异。
本调查是首次尝试了解 RBS 的各个方面。调查结果将有助于确定研究领域，并使专家之间达成共识。
