BACKGROUND: Although mortality associated with pancreatic surgery has decreased dramatically, high morbidity rates are still of major concern. This study aimed to identify the prevalence of, and risk factors for, @entity166 after pancreatic surgery. METHODS: The Japanese Society of Pancreatic Surgery conducted a multi-institutional analysis of complications in @entity1 who underwent pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) between January 2010 and December 2012. Risk factors that were significantly associated with @entity166 in univariable models were included in a multivariable logistic regression model, and a nomogram was created to predict the risk of @entity166 after pancreatectomy. RESULTS: Infectious complications occurred in 1459 (35.2 per cent) of 4147 @entity1 in the PD group and 426 (25.2 per cent) of 1692 @entity1 in the DP group (P < 0.001). Nine risk factors for @entity166 after PD were identified: male sex, age 70 years or more, body mass index at least 25 kg/m(2), other @entity5 , @entity409 , bile contamination, duration of surgery 7 h or longer, intraoperative blood transfusion and soft pancreas. Five risk factors for @entity166 after DP were identified: chronic @entity479 use, smoking, duration of surgery 5 h or more, intraoperative blood transfusion and non-laparoscopic surgery. Occurrence of a postoperative infectious complication was significantly associated with mortality and reoperation after PD (odds ratio (OR) 4.33, 95 per cent c.i. 2.01 to 9.92 and OR 3.26, 1.86 to 5.82, respectively) and DP (OR 6.32, 1.99 to 22.55; OR 3.74, 1.61 to 9.04). CONCLUSION: Prolonged operating time, intraoperative blood transfusion, bile contamination (PD) and non-laparoscopic surgery (DP) are risk factors for @entity260 that could be targeted to improve outcome after pancreatectomy.
