Multidisciplinary Diagnosis and Management of a Rare Dysplastic Adenoma Involving a Pancreas Transplant

A 52-year-old man with a history of type 1 diabetes mellitus with diabetic nephropathy who underwent simultaneous pancreas–kidney transplant over a decade ago presented with small bowel obstruction and was found by enteroscopy to have a carpeted lesion encompassing the small bowel anastomosis in the region of the donor pancreas. As endoscopic mucosal resection was impracticable because of technical limitations, the patient was referred to transplant surgical team for surgical exploration and ultimately required organ resection. This represents a unique presentation of an ampullary adenoma with high-grade dysplasia requiring device-assisted enteroscopy requiring multidisciplinary management.
