Restrictive procedures, and in particular sleeve gastrectomy (SG), although widely performed as primary bariatric surgery, seems particularly prone to need surgical revision for the above-mentioned reasons during long-term follow-up. The aim of this systematic review was to compare the long-term (5-year) safety and efficacy between Roux-en-Y gastric bypass (RYGB) and single anastomosis duodeno-ileal bypass (SADI) after \u2018failed\u2019 SG.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A systematic review was performed from 2007 to September 2024.
