To our knowledge, a pancreatic allograft duodenal bezoar has not been previously described as a cause of obstruction. A 69-year-old female presented to the emergency department (ED) with severe abdominal pain and computed tomography (CT) findings concerning for a SBO. Given imaging characteristics concerning for a mass and her complete obstruction, we performed an immediate exploratory laparotomy. Intraoperatively, a large, solidified bezoar within the pancreatic allograft duodenum and a smaller bezoar causing a SBO in the efferent jejunal limb were removed. This case reveals a previously undescribed cause of life-threatening obstruction within a pancreaticoduodenal allograft and highlights the importance of considering rare entities in pancreas transplant patients to preserve graft function and prevent further complications.<\/jats:p>","DOI":"10.3389\/frtra.2026.1706203","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T06:32:11Z","timestamp":1770013931000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Bezoar in allograft duodenum\u2014rare cause of bowel obstruction 13 years post-pancreas transplant"],"prefix":"10.3389","volume":"5","author":[{"given":"Marlena","family":"Urvater","sequence":"first","affiliation":[{"name":"The University of Queensland\u2014Ochsner Clinical School","place":["New Orleans, LA, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cora","family":"Ianiro","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Ochsner Clinic Foundation","place":["New Orleans, LA, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David S.","family":"Bruce","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Ochsner Clinic Foundation","place":["New Orleans, LA, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tuesday","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Ochsner Clinic Foundation","place":["New Orleans, LA, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik B.","family":"Finger","sequence":"additional","affiliation":[{"name":"Department of Surgery, Division of Transplantation, University of Minnesota","place":["Minneapolis, MN, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Barr","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Ochsner Clinic Foundation","place":["New Orleans, LA, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1288","DOI":"10.2214\/AJR.05.1087","article-title":"Bowel complications seen on CT after pancreas transplantation with enteric drainage","volume":"187","author":"Lall","year":"2006","journal-title":"AJR Am J Roentgenol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"139","DOI":"10.1111\/tri.13775","article-title":"Early intestinal complications following pancreas transplantation: lessons learned from over 300 cases\u2014a retrospective single-center study","volume":"34","author":"Ferrer-Fabrega","year":"2021","journal-title":"Transpl Int"},{"key":"B3","doi-asserted-by":"publisher","first-page":"346","DOI":"10.1080\/08998280.2014.11929155","article-title":"Post-transplant lymphoproliferative disorder presenting as a small bowel obstruction in a patient with pancreas transplantation alone","volume":"27","author":"Kruel","year":"2014","journal-title":"Proc (Bayl Univ Med Cent)"},{"key":"B4","doi-asserted-by":"publisher","first-page":"575","DOI":"10.1016\/j.transproceed.2004.02.034","article-title":"Small-bowel obstruction due to bezoar following pancreas transplantation with portal-enteric drainage: a case report","volume":"36","author":"Boggi","year":"2004","journal-title":"Transplant Proc"},{"key":"B5","first-page":"132","article-title":"Bezoars and concretions.
