Influencing factors for poor jaundice resolution after radical pancreaticoduodenectomy in patients with malignant obstructive jaundice / 中华消化外科杂志

ABSTRACT

Objective To investigate the influencing factors for poor jaundice resolution after radical pancreaticoduodenectomy in patients with malignant obstructive jaundice.Methods The retrospective case-control study was conducted.The clinicopathological data of 121 patients with malignant obstructive jaundice who were admitted to the Affiliated Changzhou No.2 People's Hospital of Nanjing Medical University between March 2013 and June 2018 were collected.There were 70 males and 51 females,aged (69±9)years,with a range from 39 to 85 years.Of 121 patients,112 underwent open radical pancreaticoduodenectomy,and 9 underwent totally laparoscopic radical pancreaticoduodenectomy.Observation indicators:(1) situations of jaundice resolution after pancreaticoduodenectomy;(2) influencing factors for poor jaundice resolution after pancreaticoduodenectomy.Measurement data with normal distribution were represented as Mean ± SD.Measurement data with skewed distribution were represented as M (range).Count data were described as absolute numbers.Univariate analysis was performed using the chi-square test,t test,Fisher exact probability or Mann-Whitney U test.Multivariate analysis was performed by the Logistic regression model using P＜0.10 as an inclusion criteria in the univariate analysis.Results (1) Situations of jaundice resolution after pancreaticoduodenectomy:of 121 patients,97 had good jaundice resolution after pancreaticoduodenectomy,and 24 had poor jaundice resolution after pancreaticoduodenectomy.(2) Influencing factors for poor jaundice resolution after pancreaticoduodenectomy:results of univariate analysis showd that preoperative level of serum total bilirubin,comorbidity with diabetes mellitus were influencing factors for poor jaundice resolution after pancreaticoduodenectomy (t =-2.073,x2 =10.201,P＜0.05).Postoperative pancreatic fistula was also an influencing factor for poor jaundice resolution after pancreaticoduodenectomy (P ＜ 0.05).Results of multivariate analysis showed that comorbidity with diabetes mellitus and postoperative pancreatic fistula were independent risk factors for poor jaundice resolution after pancreaticoduodenectomy (odds ratio=0.258,0.129,95％ confidence interval:0.087-0.769,0.023-0.726,P＜0.05).Conclusions Preoperative level of serum total bilirubin,diabetes mellitus,and postoperative pancreatic fistula are influencing factors for poor jaundice resolution after pancreaticoduodenectomy.Comorbidity with diabetes mellitus and postoperative pancreatic fistula are independent risk factors for poor jaundice resolution after pancreaticoduodenectomy.
