Outcome of superior mesenteric-portal vein resection during pancreatectomy for borderline ductal adenocarcinoma: results of a prospective comparative study

Background Approximately 20 % of patients affected by pancreatic ductal adenocarcinoma are amenable to surgical resection. Several tumours are reported as “borderline resectable” because of their proximity to the major vessels. In the effort to achieve a radical tumour removal, vein resection has been proposed, but its oncological benefits remain debated.
