There are no agreed definitions as to what constitutes a 'failure' of the primary bariatric procedure in relation to weight loss.
The MEDLINE database for primary research articles was searched using obesity [title] or bariatric [title] and revision [title] or revisional [title].
The MEDLINE search retrieved 174 studies. After duplicates and exclusions were removed, 60 articles underwent analysis. Fifty-one studies included inadequate weight loss or weight regain as an indication for revision: 31/51 (61 %) gave no definition of failure, 7/20 quoted <50 % of excess weight loss at 18 months and 6/20 used <25 % excess weight loss.
The majority of published studies do not define failure of bariatric surgery, and <50 % excess weight loss at 18 months was the most frequent definition identified.
关于减肥方面，对于初次减肥手术的“失败”尚无公认的定义。
使用肥胖症[标题]或减肥手术[标题]以及翻修[标题]或翻修术[标题]检索MEDLINE数据库中的原始研究文章。
MEDLINE检索到174项研究。去除重复项和排除项后，对60篇文章进行了分析。51项研究将减肥不足或体重反弹作为翻修的指征：31/51（61%）未给出失败的定义，7/20引用18个月时多余体重减轻<50%，6/20使用多余体重减轻<25%。
大多数已发表的研究未定义减肥手术的失败，18个月时多余体重减轻<50%是最常确定的定义。
