However, its use remains limited in various parts of the world due to postoperative complications. After the efficacy of this procedure was established, the focus of treatment shifted toward resolving postoperative complications. Protein-energy malnutrition after OAGB is one of the main issues that needs to be addressed. There are several operative options for patients who require revision surgery including reversal and conversion to Roux-en-Y gastric bypass (RYGB). The conversion from OAGB to RYGB is a feasible method that has shown excellent results when performed by experts in the field. Here, we present the case of a woman with symptoms of acute obstruction secondary to OAGB who underwent conversion to RYGB under emergent conditions.<\/jats:p>","DOI":"10.1093\/jscr\/rjad428","type":"journal-article","created":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T22:47:23Z","timestamp":1692744443000},"source":"Crossref","is-referenced-by-count":1,"title":["Emergent conversion from single-anastomosis gastric bypass to Roux-en-Y gastric bypass with subsequent obstruction of entero-enteric anastomosis by ascaris"],"prefix":"10.1093","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1153-5145","authenticated-orcid":false,"given":"Mauricio","family":"Palacios","sequence":"first","affiliation":[{"name":"Cirug\u00eda Bari\u00e1trica, Hospital Metropolitano , Quito 170521 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex","family":"Guachilema R","sequence":"additional","affiliation":[{"name":"Cirug\u00eda General, Hospital General Enrique Garc\u00e9s , Quito 170131 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Morocho","sequence":"additional","affiliation":[{"name":"Anestesiolog\u00eda, Hospital General Enrique Garces , Quito 170131 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Lisintu\u00f1a","sequence":"additional","affiliation":[{"name":"Cirug\u00eda General y Laparosc\u00f3pica, Hospital Metropolitano , Quito 170521 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julio","family":"Yepez","sequence":"additional","affiliation":[{"name":"M\u00e9dico Internista, Hospital Metropolitano , Quito 170521 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariela","family":"Andrade","sequence":"additional","affiliation":[{"name":"Cirug\u00eda General y Laparosc\u00f3pica, Hospital Metropolitano , Quito 170521 , Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,8,22]]},"reference":[{"key":"2023082222471459200_ref1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.ijscr.2020.08.032","article-title":"Conversion from mini bypass to laparoscopic roux en Y gastric bypass in an emergency setting: case report and literature review","volume":"75","author":"Perez Galaz","year":"2020","journal-title":"Int J Surg Case Rep"},{"key":"2023082222471459200_ref2","doi-asserted-by":"crossref","first-page":"32","DOI":"10.17476\/jmbs.2021.10.1.32","article-title":"Conversion of one-anastomosis gastric bypass (OAGB) to roux-en-Y gastric bypass (RYGB) is effective in dealing with late complications of OAGB: experience from a tertiary bariatric Center and literature review","volume":"10","author":"Voon","year":"2021","journal-title":"J Metab Bariatr Surg"},{"key":"2023082222471459200_ref3","doi-asserted-by":"crossref","first-page":"568","DOI":"10.1016\/j.ciresp.2019.07.012","article-title":"Revisional bariatric surgery due to failure of the initial technique: 25 years of experience in a specialized unit of obesity surgery in Spain","volume":"97","author":"Mora Oliver","year":"2019","journal-title":"Cir Esp (Engl Ed)"},{"key":"2023082222471459200_ref4","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1016\/j.soard.2021.10.019","article-title":"Conversion from one-anastomosis gastric bypass to roux-en-Y gastric bypass: when and why-a single-center experience of all consecutive OAGB procedures","volume":"18","author":"Jedamzik","year":"2022","journal-title":"Surg Obes Relat Dis"},{"key":"2023082222471459200_ref5","doi-asserted-by":"crossref","first-page":"2956","DOI":"10.1007\/s11695-017-2726-2","article-title":"Complications following the mini\/one anastomosis gastric bypass (MGB\/OAGB): a multi-institutional survey on 2678 patients with a mid-term (5 years) follow-up","volume":"27","author":"Musella","year":"2017","journal-title":"Obes Surg"},{"key":"2023082222471459200_ref6","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1016\/j.ijsu.2019.07.003","article-title":"Retrospective cohort study of 925 OAGB procedures.
