Laparoscopic conversion to Roux-en-Y gastric bypass (LRYGB) is one of the rescue strategies.<h4>Objectives</h4>To analyze short- and long-term results of reoperative LRYGB after failed LAGB.<h4>Setting</h4>Three European expert bariatric center (2 university hospitals and 1 regional hospital).<h4>Methods</h4>A retrospective review of prospectively collected data, including all consecutive patients submitted to revisional LRYGB for failed LAGB between 1999 and 2013, was performed. Complications were classified according to the Dindo-Clavien system. Long-term results in terms of weight loss were analyzed in a subgroup of patients.<h4>Results</h4>A total of 642 patients (569 women and 73 men) were included. Mean±standard deviation operating time was 188±43 minutes. There was no mortality and an overall complication rate of 9.7%, including 3.6% major complications, with no difference between the 1- or 2-step approaches. Follow-up rate was 88% at 10 years for the Swiss patient cohort. The mean excess body mass index loss was between 65% and 70% throughout the study period, and the mean total weight loss was between 28% and 30% based on the maximum weight. The mean body mass index decreased from 44.7 kg/m(2) before LAGB to 31.6, 32.2, and 32.5 kg/m(2) at 1, 5, and 10 years after revision.<h4>Conclusions</h4>Revisional LRYGB is well tolerated and feasible after failed LAGB. A 1-step approach, in cases without erosion, does not increase operative morbidity. Results up to 10 years after revision are comparable to those reported after primary LRYGB.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26077700","pmcid":null,"openalex_id":null,"authors":[],"funders":[],"total_grants":0,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":null,"license":null,"oa_locations":[],"fields_of_study":[],"mesh_terms":["Humans","Obesity, Morbid","Postoperative Complications","Laparoscopy","Treatment Outcome","Gastric Bypass","Gastroplasty","Reoperation","Retrospective Studies","Follow-Up Studies","Time Factors","Adult","Female","Male","Operative Time"],"keywords":["Long-term","Complications","Roux-en-y Gastric Bypass","Gastric Banding","Revisional Surgery"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-01T11:51:29.687637Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
