Risk and Predictors of Postoperative Morbidity and Mortality After Pancreaticoduodenectomy for Pancreatic Neuroendocrine Neoplasms A Comparative Study With Pancreatic Ductal Adenocarcinoma

摘要

Objectives Pancreaticoduodenectomy (PD) is associated with a high risk of postoperative complications and mortality. The aim of this study was to compare postoperative morbidity after PD in patients undergoing resections for pancreatic neuroendocrine neoplasms (PanNENs) with patients undergoing the same resection for pancreatic ductal adenocarcinoma (PDAC). Methods Data of 566 patients from 3 European tertiary referral centers between 1998 and 2014 were considered. Results Overall, 566 patients (179 with PanNENs, 387 with PDAC) who underwent PD were analyzed. Patients with PanNENs were significantly younger (56 vs 64 years, P < 0.0001). The consistency of the pancreas was soft in 147 patients (82%) with PanNENs and in 162 patients (42%) with PDAC (P < 0.0001). Patients in the PanNENs group had a significantly higher rate of pancreatic fistula (P < 0.0001), bile leak (P = 0.004), abdominal collection (P = 0.017), and development of sepsis (P = 0.042). No differences in terms of overall postoperative complications, median length of stay, and in-hospital mortality were found. On multivariate analysis sex (male), PanNENs indication, blood transfusion, and a soft pancreatic texture were independent predictors of pancreatic fistula after PD. Conclusions Pancreaticoduodenectomy for PanNENs is associated with higher rate of surgical-specific postoperative complications than those for PDAC.
