Ductal adenocarcinoma of the pancreatic head: A focus on current diagnostic and surgical concepts

Table 4 Improvement of radicality of resection

Resection	Exclusion of resection
Standard lymph node clearance for PPPD/CKW include the regional peripancreatic lymph nodes, hepato-duodenal ligament, common hepatic artery, portal vein, cranial portion of the superior mesenteric vein, right border along the mesenteric superior artery and celiac trunk	Extended lymphadenectomy can not be recommended
Vascular resection of the portal vein or superior mesenteric vein is feasible and safe and should not be an exclusion criterion in curative surgery	Thrombosis of the mesenteric-portal vein or tumoral infiltration > 180° of these vascular structures are contraindications in attempting curative resection

PPPD: Pylorus preserving pancreaticoduodenectomy; CKW: Classic Kausch-Whipple.
