ABSTRACT
BACKGROUND: Portal vein resection and reconstruction in locally advanced pancreatic cancer represents a potentially curative treatment in selected patients without increasing surgical mortality. However, vascular reconstruction after segmental venous resection is challenging. The parietal peritoneum has emerged as a venous substitute but few reports include its use as a tubular graft. We report a retrospective series of portal vein reconstruction using a falciform ligament tubular graft during pancreaticoduodenectomy. MATERIAL AND METHODS: Technical aspects and short-term morbidity and mortality after pancreaticoduodenectomy with falciform ligament tubular graft interposition were analyzed. RESULTS: Among 21 patients who used parietal peritoneum for venous substitution between 2015 and 2019, eight underwent pancreaticoduodenectomy with venous resection and reconstruction using interposition of falciform ligament tubular graft. The mean duration of surgery and clamping time were 350 and 27 min, respectively. No perioperative blood transfusion was required. All the grafts were patent the day after surgery. No complication related to venous obstruction was detected during the hospital stay. Two patients had postoperative pancreatic fistula. No further intervention was needed. The 90-day mortality was null. CONCLUSIONS: The use of interposition of falciform ligament tubular graft for portal venous reconstruction during pancreaticoduodenectomy seems to be a reliable, inexpensive, and safe procedure.

Resection of the inferior vena cava may be required in the courses of oncological surgeries for the tumors originating from or invading it. Management of the remaining defect depends on the extension of the resection. Partial or complete replacement of the inferior vena cava, with a patch or interposition graft, may be required. Standard techniques for the reconstruction with a prosthetic material or the autologous veins can be associated with the prosthetic graft infection, high cost, long-standing anticoagulation, technical difficulties, and/or need for extra incisions. The use of the autologous peritoneum represents an easy and inexpensive alternative for the partial and complete inferior vena cava reconstructions.
