Successful embolization with subsequent pancreaticoduodenectomy for intraductal papillary mucinous neoplasm hemorrhage: a case report and review of literature.

Abstract

Although various complications associated with intraductal papillary mucinous neoplasms have been reported, including acute pancreatitis, duct perforation, and fistula formation, spontaneous bleeding, especially life-threatening bleeding, is infrequent. In this case, emergency pancreatic resection might be one of the therapeutic options, which is associated with poor postoperative outcomes. An 87-year-old woman presented to our hospital with severe anemia (hemoglobin, 4.5 g/dl). Contrast-enhanced computed tomography revealed a large cystic lesion in the pancreatic head measuring 15 cm, with some solid components and an adjacent hematoma, suggestive of intra-cystic hemorrhage of the intraductal papillary mucinous neoplasm. The patient was hemodynamically unstable and had hypotension. After transcatheter arterial embolization, the patient became hemodynamically stable. Subsequently, an elective pylorus-preserving pancreaticoduodenectomy was successfully performed. Preoperative embolization was effective for subsequent elective pancreaticoduodenectomy in patients with severe intraductal papillary mucinous neoplasm bleeding.
