Résumé
Objective: The purpose of this study was to investigate the rate and reasons and also the risk factors for unplanned reoperation after pancreatoduodenectomy (PD) in a single center. Patients and Methods: This retrospective analysis included patients who underwent PD in the First Affiliated Hospital of Nanchang University between January 2010 and January 2018. The patients were divided into nonreoperation and reoperation groups according to whether they underwent unplanned reoperation following the primary PD. The incidence and reasons were examined. In addition, multivariate logistic regression analysis was performed to identify the risk factors for unplanned reoperation. Results: Of the 330 patients who underwent PD operations, 22 (6.67%) underwent unplanned reoperation. The main reasons for reoperation were postpancreaticoduodenectomy hemorrhage (PPH) (12/22 [54.5%]) and pancreaticoenteric anastomotic (PEA) leak (5/22 [22.7%]). Multivariate logistic regression analyses identified that diabetes (odds ratio [OR], 3.70; 95% confidence interval [CI], 1.06–12.90; P = 0.04), intraoperative blood loss ≥400 mL (OR, 4.06; 95% CI, 1.29–12.84; P = 0.02), occurrence of postoperative complications in the form of PPH (OR, 30.67; 95% CI, 8.85–106.31; P < 0.001), and PEA leak (OR, 11.53; 95% CI, 3.03–43.98, P < 0.001) were independent risk factors for unplanned reoperation. Conclusions: Our results suggest that diabetes, intraoperative blood loss ≥400 mL, PPH, and PEA leak were independent risk factors for unplanned reoperation after primary PD
