"Mesopancreas-first" radical resection of pancreatic head cancer following the Cattell-Braasch-Valdoni maneuver: Appreciating the legacy of pioneers in visceral surgery.

The "artery-first" approach pancreaticoduodenectomy, with maximal mesopancreas excision and central vascular ligation, represents the current principal determinants of radicality in pancreatic head cancer resection. However, these modifications at the resection stage of pancreaticoduodenectomy constitute extremely demanding and technically complicated procedures. Among the most critical contributing factors in the difficulty of artery-first approaches is the spiral configuration of the mesoduodenum and proximal mesojejunum around the superior mesenteric artery axis.
