BACKGROUND: There are no agreed definitions as to what constitutes a 'failure' of the primary bariatric procedure in relation to weight loss. METHODS: The MEDLINE database for primary research articles was searched using obesity [title] or bariatric [title] and revision [title] or revisional [title]. RESULTS: 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. CONCLUSIONS: 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.
