Intestinal Autotransplantation and In-Situ Resection of Recurrent Pancreatic Head Intraductal Tubulopapillary Neoplasm with Portal Cavernoma: A Case Report

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Intraductal tubulopapillary neoplasm (ITPN) is a new entity of a rare premalignant pancreatic neoplasia, and a radical curative resection is indicated. As with other tumors of the root of the mesentery, the proximity of the lesion to large splanchnic vessels, abdominal aorta, and inferior vena cava poses major risks of a massive hemorrhage and visceral ischemia using conventional surgical techniques. At times, these lesions are amenable for resection using novel techniques developed from organ transplantation. Multivisceral (allo-) transplantation should be considered when radical resection of a benign tumor is likely to compromise portal flow and possibly precipitate acute liver failure, but it may be associated with a long waitlist time and tumor progression. Autotransplantation offers a safe and curative resection of otherwise inoperable tumors in a bloodless field, an excellent exposure, and prevention of warm ischemic injury to the affected viscera, which are then autotransplanted. Methods: We describe the en bloc resection of a large and recurrent ITPN of the pancreas, distal stomach, proximal duodenum, transverse colon, superior mesenteric vein, and portal cavernoma, followed by intestinal autotransplantation. Results: A complete tumor resection was achieved with negative margins, adequate cold preservation of the reimplanted intestine, and without significant hemorrhage. The patient was discharged from the hospital 10 days later. The histopathologic examination revealed free-margin resection of ITPN with an associated invasive carcinoma. The patient received adjuvant chemotherapy with folinic acid, fluorouracil, and oxaliplatin and remains disease-free 20 months after surgery. Conclusions: Autotransplantation offers curative resection of otherwise unresectable lesions of the root of the mesentery.
