This paper reviews reoperations rates for short- and long-term complications following secondary bariatric procedures and need for further bariatric surgery. The search revealed 28 papers (1317 secondary cases) following at least 75 % of patients for 12 months or more. For adjustable gastric banding (AGB), rebanding had higher re-revisional rates than conversions into other procedures. Conversion of AGB to Roux-en-Y gastric bypass had the highest number of short- (10.7 %) and long-term (22.0 %) complications. We estimated 194 additional reoperations per 1000 patients having a secondary procedure, 8.8 % needing tertiary surgery. Despite being poorly reported, risks of reoperations for long-term complications and tertiary bariatric surgery are higher than usually reported risks of short-term complications and should be taken into account when choosing a secondary bariatric procedure and for economic evaluations.
