[Pylorus-Preserving Pancreaticoduodenectomy (PPPD) with Segmental Portal Vein Resection]

Pylorus-preserving partial pancreatoduodenectomy is a complex visceral operation, especially when simultaneous resection and reconstruction of the portal venous axis is necessary. Pancreatic anastomosis plays a decisive role in this procedure, since postoperative pancreatic fistula (POPF) is a frequent complication, with serious consequences (morbidity and mortality) for the affected patient. Various techniques are available for anastomosing the residual pancreas: the duct-to-mucosa pancreaticojejunostomy, invaginating pancreatojejunostomy, Blumgart anastomosis and pancreatogastrostomy.

Pylorus-preserving pancreaticoduodenectomy (PPPD) with portal vein resection.

A standardised and structured approach to pylorus-preserving partial pancreatoduodenectomy helps the surgeon to perform this procedure safely. Performing a simultaneous portal vein resection increases the complexity of the procedure, but nonetheless, if infiltration of the portal venous axis is suspected, the indication for en-bloc resection should be given generously, as intraoperatively it is not possible to differentiate reliably between inflammatory adherence and tumour infiltration and portal vein/V.-mesenterica-superior-resection does not increase morbidity and mortality. The choice of the surgical technique for anastomosing the residual pancreas should be made by the surgeon on the basis of his expertise and, if necessary, adapted to the patient's situs, since the most important pancreatic anastomosis techniques appear to be equivalent according to the current evidence.
