A). The pancreatic head was dissected laterally of the Superior Mesenteric Vein (SMV) and is turned to the right side after mobilization. The mesopancreas strains itself dorsally of themesenteric vessels as a whitish-firm, fatty tissue-like layer. PH = Pancreatic Head; SMV = Superior Mesenteric Vein; PV = Portal Vein; MP = Mesopancreas Inline graphic. B). Resection of the pancreas and mesopancreas dorsally of the mesenteric vessels en bloc. PH = Pancreatic Head; MP = Mesopancreas Inline graphic; PAF = Preaortic Fascia, PC = Plexus Coeliacus, PMS = Plexus Mesentericus superior. C). Macroscopically, in the dissected en-bloc specimen of the pancreas and mesopancreas nerve plexuses are found running from the dorsal surface of the pancreatic head to the mesopancreas to establish a perineural plane. PH = Pancreatic Head;NP = Nerve Plexus; SMV = Superior Mesenteric Vein; PV = Portal Vein; MP = Mesopancreas Inline graphic. D). The nerve plexus of the dorsal site of the pancreatic head is depicted in a detailed view after preparation of the layer between pancreas and mesopancreas. PH = Pancreatic Head; NP = Nerve Plexus of the dorsal margin of the pancreatic head.
