Revisional strategies comprised Minimizer ring implantation and pouch-based revisions. Outcomes assessed included percentage total weight loss (%TWL), body mass index (BMI) changes, postoperative complications, reinterventions, and functional tolerance at 3, 6, and 12 months. Non-parametric statistical methods were applied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>27 patients were analyzed (14 Minimizer ring implantations, 13 pouch revisions). Both strategies achieved progressive weight loss with no significant differences in %TWL at 3, 6 and 12 months. Early postoperative complication rates were similar in both groups. Minimizer ring implantation was associated with a higher rate of late intolerance and secondary interventions leading to ring removal.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Within the available 12-month follow-up, no statistically significant difference in weight loss was detected between Minimizer ring implantation and pouch revisional surgery. Minimizer ring implantation was associated with a higher observed burden of intolerance and secondary interventions in this cohort. Pouch revision may provide anatomical correction without foreign-body-related complications. These findings should be considered hypothesis-generating and suggest that future studies should assess cumulative reintervention burden across revisional strategies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00423-026-04075-6","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T03:28:08Z","timestamp":1779334088000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Minimizer ring implantation versus pouch revision for weight regain and functional failure after Roux-en-Y gastric bypass: A retrospective single-centre analysis"],"prefix":"10.1007","volume":"411","author":[{"given":"Marius","family":"Arbogast","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Hauf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Schaffner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Biraima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Soll","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"issue":"2","key":"4075_CR1","doi-asserted-by":"publisher","first-page":"48","DOI":"10.5412\/wjsp.v4.i2.48","volume":"4","author":"RS Stubbs","year":"2014","unstructured":"Stubbs RS (2014) What makes a gastric bypass a good gastric bypass?
