Popis: The proximal jejunal vein which branches from the dorsal side of the superior mesenteric vein (SMV) usually drains the inferior pancreatoduodenal veins (IPDVs) and contacts the uncinate process of the pancreas. We focused on this vein, termed the proximal dorsal jejunal vein (PDJV), and evaluated the anatomical classification of the PDJV and surgical outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) with PDJV involvement (PDJVI). The jejunal veins that branch from the dorsal side of the SMV above the inferior border of the duodenum are defined as PDJVs. We investigated 121 patients who underwent upfront pancreaticoduodenectomy for PDAC between 2011 and 2017; PDJVs were resected in all patients. The anatomical classification of PDJV was evaluated using multidetector computed tomography. Surgical and prognostic outcomes of pancreticoduodenectomy for PDAC with PDJVI were evaluated. The PDJVs were classified into seven types depending on the position of the first and second jejunal veins relative to the superior mesenteric artery. In all patients, the morbidity and mortality rates were 15.7 and 0.8%, respectively. The rates for parameters including SMV resection, presence of pathological T3–4, R0 resection, and 3-year survival were 46.2, 92.3, 92.3, and 61.1%, respectively, when there was PDJVI (n = 13). When there was no PDJVI (n = 108), the rates were 60.2, 93.5, 86.1, and 58.3%, respectively. Overall, there were no significant differences. Pancreaticoduodenectomy with PDJV resection is feasible for PDAC with PDJVI and satisfactory overall survival rates are achievable. It may be necessary to reconsider the resectability of PDAC with PDJVI.
