Pylorus-preserving pancreaticoduodenectomy
Also written as: PPPD — Pylorus-preserving pancreaticoduodenectomy
A modification of the Whipple procedure that preserves the pylorus and antrum to maintain gastric function.
Full Definition
Pylorus-preserving pancreaticoduodenectomy (PPPD) is a surgical technique for pancreatic head resection that maintains the pyloric sphincter and gastric antrum, in contrast to the classical Whipple procedure. This modification aims to reduce postoperative gastric dysfunction, improve nutritional outcomes, and decrease dumping syndrome. The procedure involves careful preservation of the right gastric and right gastroepiploic vessels while achieving the same oncological resection as traditional pancreaticoduodenectomy. Studies suggest comparable long-term survival outcomes with potential functional advantages.
