These are usually asymptomatic and discovered incidentally. Small bowel obstruction due to gastrointestinal stromal tumour in neurofibromatosis 1 is rare, especially in young adults. We report a 24-year-old man with neurofibromatosis type 1 who presented with right upper quadrant pain and biochemical features of acute cholecystitis. During laparoscopic cholecystectomy, unexpected small bowel dilatation prompted conversion to laparotomy, revealing obstruction from a large multifocal jejunal gastrointestinal stromal tumour. This case highlights the rarity of such a presentation and the importance of surgical adaptability intraoperatively.<\/jats:p>","DOI":"10.1093\/jscr\/rjag030","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T12:33:03Z","timestamp":1768307583000},"source":"Crossref","is-referenced-by-count":0,"title":["Small bowel obstruction from jejunal gastrointestinal stromal tumour in a young adult with neurofibromatosis type 1: a case report"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3937-9631","authenticated-orcid":false,"given":"Anaan","family":"Fareed","sequence":"first","affiliation":[{"name":"Surgical Services, John Hunter Hospital , Lookout Road, New Lambton Heights, Newcastle, NSW 2305 ,","place":["Australia"]},{"name":"School of Medicine and Public Health, University of Newcastle , University Drive, Callaghan, Newcastle, NSW 2308 ,","place":["Australia"]},{"name":"Department of General Surgery, Armidale Rural Referral Hospital , 226 Rusden Street, Armidale, NSW 2350 ,","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jordan","family":"Barrett","sequence":"additional","affiliation":[{"name":"John Hunter Hospital , Lookout Road, New Lambton Heights, Newcastle, NSW 2305 ,","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Al-Mashat","sequence":"additional","affiliation":[{"name":"Surgical Services, John Hunter Hospital , Lookout Road, New Lambton Heights, Newcastle, NSW 2305 ,","place":["Australia"]},{"name":"School of Medicine and Public Health, University of Newcastle , University Drive, Callaghan, Newcastle, NSW 2308 ,","place":["Australia"]},{"name":"Department of General Surgery, Armidale Rural Referral Hospital , 226 Rusden Street, Armidale, NSW 2350 ,","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjaya","family":"Karunaratne","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Armidale Rural Referral Hospital , 226 Rusden Street, Armidale, NSW 2350 ,","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,1,30]]},"reference":[{"key":"2026020600225764300_ref1","doi-asserted-by":"publisher","first-page":"712","DOI":"10.1136\/jmg.26.11.712","article-title":"A genetic study of von Recklinghausen neurofibromatosis in south East Wales.
