It has been suggested that the incidence of portal vein thrombosis is directly related to many risk factors inherent in the bariatric population as well as factors related to local and systemic effects of laparoscopic surgery. Possible aetiologies vary from systemic inherited hypercoagulable states to a direct inflammatory reaction of portosystemic vessels. Here we present a case report of a 47-year-old obese women who underwent a robotic sleeve gastrectomy with subsequent development of a main portal vein, complete right intrahepatic portal vein and splenic vein thrombosis ultimately found to have a compound mutation of the methylenetetrahydrofolate reductase C677T and A1298C alleles.<\/jats:p>","DOI":"10.1136\/bcr-2020-236202","type":"journal-article","created":{"date-parts":[[2020,12,22]],"date-time":"2020-12-22T18:18:21Z","timestamp":1608661101000},"page":"e236202","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Portomesenteric thrombosis after robotic sleeve gastrectomy"],"prefix":"10.1136","volume":"13","author":[{"given":"Omkaar","family":"Jaikaran","sequence":"first","affiliation":[{"name":"Department of Surgery, New York University Medical Center, Brooklyn, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Derek","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Surgery, New York University Medical Center, Brooklyn, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Binetti","sequence":"additional","affiliation":[{"name":"Department of Surgery, Nuvance Health, Rhinebeck, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vadim","family":"Meytes","sequence":"additional","affiliation":[{"name":"Department of Surgery, Nuvance Health, Rhinebeck, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,12,22]]},"reference":[{"key":"2025082802252867000_13.12.e236202.1","doi-asserted-by":"crossref","first-page":"2360","DOI":"10.1007\/s11695-017-2637-2","article-title":"Portomesenteric vein thrombosis Post-Laparoscopic sleeve gastrectomy: case series and literature review","volume":"27","author":"AlSabah","year":"2017","journal-title":"Obes Surg"},{"key":"2025082802252867000_13.12.e236202.2","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-011-0445-7"},{"key":"2025082802252867000_13.12.e236202.3","doi-asserted-by":"crossref","first-page":"30","DOI":"10.4103\/2347-2618.158700","article-title":"Liver and bowel infarction secondary to portomesenteric vein thrombosis following laparoscopic sleeve gastrectomy","volume":"3","author":"De","year":"2015","journal-title":"Saudi J Obes"},{"key":"2025082802252867000_13.12.e236202.4","unstructured":"Franco J , Castillo J , Vel\u00e1quez A .
