Duodenal intussusception due to periampullary duodenal adenoma: A case report

Abstract

Duodenal intussusceptions are uncommon due to their fixed location in retroperitoneum except when associated with bowel malrotation abnormalities. We present a case of recurrent duodenojejunal intussusception in a 34-year-old female diagnosed on imaging. The lead point, in our case, was periampullary duodenal tubulovillous adenoma which was confirmed on endoscopy and subsequent punch biopsy. The patient underwent segmental duodenal resection anastomosis preserving the ampulla with reduction of the intussuceptum and fixation of the jejunal loops and its mesentery.
