Objective To analyze the risk factors of bile duct injuries in laparoscopic cholecystectomy.Methods The clinical data of 11 243 patients who underwent laparoscopic cholecystectomy between October 1992 and December 2013 in the Xianyang Center Hospital were studied retrospectively.The risk factors of bile duct injuries were analyzed using the Chi-square test to determine the independent risk factors of bile duct injuries.Results Univariate analysis showed that bile duct injuries were associated with male,age ≥65 years,BMI ≥25 kg/m2,staging of inflammation,gallbladder atrophy on ultrasonography,thickness of gallbladder wall on ultrasonography,anatomy of Calot 's triangle and operator's experience (all P < 0.05).Multi-factor and non conditional Logistic regression analyses showed that the independent risk factors of bile duct injury were old men,gallbladder atrophy,anatomy of Calot's triangle and operator's experience (All P < 0.05).Conclusion Old men,gallbladder atrophy,anatomy of Calot's triangle and operator's experience were independent risk factors of bile duct injuries.

Objective To compare the differences between two statistical methods for evaluating non-sensitivity of pathogenic bacteria to antimicrobial agents,and explore effect of non-consideration of clinical background on evalua-ting extent of bacterial resistance.Methods Data of Staphylococcus aureus and Acinetobacter spp .in a hospital in the first half year of 2008,2010 and 2013 were collected and conducted statistical analysis with two methods (me-thod 1 :based on all clinically isolated bacteria;method 2 :based on infection-related non-repetitive bacteria),two methods for evaluating bacterial non-sensitive rates to antimicrobial agents were compared.Results The non-sensi-tive rates of Acinetobacter spp .to various antimicrobial agents :statistical results by using method 1 were generally higher than those using method 2,absolute difference between two statistical methods was 10.46%-33.77%;the non-sensitive rates of Staphylococcus aureus to various antimicrobial agents :except compound sulfamethoxazole in 2010 and 2013(difference were 6.17% and 10.21 % respectively),penicillin G (difference was 3.86%),erythromy-cin (difference was 2.71 %),and azithromycin in 2013 (difference was 2.43%),statistical results by using method 1 were generally higher than those using method 2,absolute difference between two statistical methods was 0-18.04%.Conclusion There are deviation in the non-sensitive rates of bacterial strains to antimicrobial agents by using two different statistical methods,deviation is larger in Acinetobacter spp ..The resistance level might be incorrectly higher when evaluating the resistance status without considering clinical background of bacteria.

Objective:
To understand the prevalence and influencing factors of dyslipidemia in the residents aged 40 years and over in the rural areas of Liaoning Province,so as to provide basis for the development of targeted prevention and control measures.
Methods:
From September 2017 to May 2018,by stratified cluster random sampling method,the residents aged 40 years or above from 19 villages in Liaoning Province were selected. Demographic features,height,weight,blood pressure and lipid level were collected. A logistic regression model was applied to explore the influencing factors for dyslipidemia.
Results:
A total of 10 926 residents were recruited,with an average age of (59.97±10.08)years. The crude and standardized prevalence rate of dyslipidemia was 30.96% and 29.68%. The results of multivariate logistic regression analysis showed that women(OR=1.323,95%CI:1.189-1.473),50-69 years old(OR:1.238-1.333,95%CI:1.075-1.523),a high school education or below(OR:0.585-0.635,95%CI:0.439-0.842),hypertension(OR=1.398,95%CI:1.273-1.534),diabetes(OR=2.137,95%CI:1.918-2.381),overweight or obesity(OR=2.101,95%CI:1.916-2.303), meat-based meals(OR=1.306,95%CI:1.144-1.492)and vegetables intake less than 5 days a week(OR:1.169-1.387,95%CI:1.004-1.796) were associated with dyslipidemiais.
Conclusions
The prevalence rate of dyslipidemia was 30.96% in the rural residents aged 40 years and over in Liaoning Province. People who were females,who were 50-69 years old,and who suffered from hypertension,diabetes,overweight or obese,might take their lipid levels into consideration.

Objective:To compare the embedding anastomosis with the intermittent eversion anastomosis on the pancreatic fistula rates after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 116 patients who underwent LPD at the Center Hospital of Xianyang City affiliated to Xi' an Jiaotong University Health Science Center from March 2016 to March 2020 were retrospectively studied. According to the method of pancreaticojejunostomy used, these patients were divided into the following two groups: the embedding anastomosis group ( n=55) and the intermittent eversion anastomosis group ( n=61). The duration of pancreaticojejunostomy, bilioenterostomy and gastrointestinal anastomoses, and the amounts of intraoperative blood loss and postoperative complication rates were compared between the two groups. Results:Of 116 patients in this study, there were 67 males and 49 females, with a median age of 61.5 years. No perioperative death occurred in the 2 groups. The operation time, digestive tract reconstruction time and pancreaticojejunostomy time in the embedded anastomosis group were (260±20), (65±15) and (35±15) min, respectively, which were significantly lower than those in the intermittent eversion anastomosis group (305±25), (81±25) and (45±12) min, (all P<0.05). The grade A and B pancreatic fistula rates in the embedded anastomosis group were 27.3%(15/55) and 21.8%(12/55), respectively, which were significantly higher than those in the intermittent eversion anastomosis group [8.2%(5/61) and 6.6%(4/61)], (all P<0.05). The postoperative hospital stay in the intermittent eversion anastomosis group (10.3±1.1) d was significantly lower than that in the embedding anastomosis group [(15.2±3.2) d, P<0.05]. Conclusion:In LPD, when compared with embedded pancreaticojejunostomy, intermittent eversion pancreaticojejunostomy reduced the postoperative pancreatic fistula rate and shortened the postoperative hospital stay.

Objective:To evaluate the efficacy of total laparoscopic surgery vs. open surgery for hilar cholangiocarcinoma. Methods:The clinical data of 45 patients undergoing laparoscopic radical resection of hilar cholangiocarcinoma and 42 patients by open surgery from Mar 2017 to Mar 2021 were retrospectively analyzed.Results:There was no significant difference in demographics, Bismuth classification and excision extension between the two groups (all P>0.05). The laparoscopic surgery used longer time ( t=-1.366, P<0.05). The intraoperative blood loss, number of lymph node dissection and postoperative hospital stay favored laparoscopic method( t=0.043, t=0.026, t=-1.852, P<0.05). R 0 radical resection rate,postoperative complications were also in favor of laparoscopic surgery ( χ2=3.216, χ2=2.566, all P<0.05). There was no significant difference in postoperative pathology and in hospital expenses (all P>0.05). The 1- and 3-year survival rate of the laparoscopic group was superior (all P<0.05). Conclusions:In spite of longer operational time,patients in laparoscopic hilar cholangiocarcinoma radical resection group have shorter postoperative in hospital stay and longer postoperative survival time.
