Comparison of postoperative early and late complications between pancreas-sparing duodenectomy and pancreatoduodenectomy.

PURPOSE: Pancreas-sparing duodenectomy (PSD) represents an alternative procedure to pancreatoduodenectomy (PD) for patients with duodenal neoplasms. METHODS: The postoperative early and late complications of 21 patients who underwent PSD between 1992 and 2014 were compared with those of 44 patients with soft pancreatic parenchyma who underwent PD between 2009 and 2014. RESULTS: The median operation time and blood loss were less in the PSD group than in the PD group (P < 0.001). The overall incidence of early complications was less in the PSD group than in the PD group (PSD with ampullectomy vs. PSD without ampullectomy vs. PD; 45.5 vs. 20.0 vs. 56.8 %). The incidence of pancreatic fistula formation and overall incidence of late complications were also less in the PSD group than in the PD group (P = 0.031, 0.020). There were no complications related to the pancreatic endocrine or exocrine functions in the PSD group. CONCLUSION: PSD is a less-invasive procedure and has the advantage over PD of preserving the pancreas.
