Methods: The retrospective case-control study was adopted. The clinical data of 200 patients who underwent pancreatico-duodenectomy at the Third Affiliated Hospital of Inner Mongolia Medical University from January 2010 to June 2015 were collected. The patients underwent Whipple procedure or pylorus-preserving pancreaticoduodenectomy according to the tumor site. Observation indicators included: (1) postoperative complications using Clavien-Dindo classification;(2) univariate and multivariate analyses: patients' basic information, surgery-related factors, pancreas-related factors;(3) relationship between independent risk factors and Clavien-Dindo classification of complications after pancreaticoduodenectomy. The chi-square test was applied to univariate analysis and categorical data. The comparison between groups was done by using independent samples nonparametric test (Kolmogorov-Smirnov Z), and multivariate analysis was done by using Logistic regression model. Results: (1) Postoperative complications: Of 200 patients, 122 underwent Whipple procedure and 78 underwent pylorus-preserving pancreaticoduodenectomy, including 6 cases combined with vascular reconstructions and 1 case with RFA of liver tumors. Ninety-eight patients had postoperative complications, including 41 patients with no less than 2 types of complications. After surgery, pancreatic fistula was detected in 80 patients, including 42 cases with grade A, 28 cases with grade B and 10 cases with grade C;incisional infection in 29 patients;gastric retention in 24 patients;intra-abdominal infection in 16 patients;intra-abdominal hemorrhage in 10 patients, including 8 patients receiving interventional treatment;biliary leakage in 7 patients and unplanned reoperation in 2 patients. Three patients were dead during hospitalization. The incidences of complications in grade Ⅰ, Ⅱ, Ⅲ (Ⅲ a and Ⅲ b), Ⅳ and Ⅴ of Clavien-Dindo classification were 28.00% (56/200), 13.00% (26/200), 5.00% (10/200), 1.50% (3/200) and 1.50% (3/200). (2) Univariate and multivariate analyses: The results of univariate analysis showed that body mass index (BMI) and pancreas texture were risk factors affecting complications after pancreaticoduodenectomy (χ2 = 6.483, Z = -3.189, p < .05). The results of multivariate analysis showed that BMI > 23.9 kg/m2 and soft pancreas were independent risk factors affecting complications after pancreaticoduodenectomy (OR = 2.044, 1.649, 95% confidence interval: 1.212-3.447, 1.194-2.275). (3) The relationship between independent risk factors and Clavien-Dindo classification of complications after pancreaticoduodenectomy was analyzed. There were statistically significant differences between BMI or pancreas texture and Clavien-Dindo classification of complications after pancreaticoduodenectomy (χ2 = 13.897, 27.077, p < .05). Conclusions: Clavien-Dindo classification of complications after pancreaticoduodenectomy contributes to comprehensive com-parison and evaluation, and this type of classification in this study mainly refers to grade I and II. Reducing BMI and good management of pancreatic stump may improve Clavien-Dindo classification of complications after pancreaticoduodenectomy.展开更多
