Clinical Study On Postoperative Infection Of Abdominal Surgical Site In Hepatobiliary And Pancreatic Surgery Of A Tertiary Hospital In Yunnan Province

Objective: To study and explore the incidence of surgical site infection(SSI)after hepatobiliary pancreatic surgery and the related risk factors of SSI,so as to provide a reference for the prevention of SSI after hepatobiliary pancreatic surgery in our hospital.Methods: A total of 208 adult patients who underwent abdominal surgery in the Department of Hepatobiliary and Pancreatic Surgery of our hospital from January2021 to December 2021 were selected,including 28 patients with SSI as the case group and 180 patients without SSI as the control group.The general data and perioperative clinical data of the two groups of patients were collected through the electronic medical record system of the hospital.Patients’ general information(such as age,gender,Body Mass Index(BMI),underlying diseases,etc.)and surgeryrelated information(surgical method,operation time,ASA score,intraoperative blood loss,operation time,incision grade,incision classification,etc.)were included.The data were input by Excel and analyzed by SPSS,and the relevant count data were classified.The chi-square test was used for univariate analysis to screen the factors affecting the occurrence of SSI.The statistically significant data in chi-square test were included in multivariate logistic regression analysis to determine the possible risk factors.Results: The incidence of SSI after hepatobiliary and pancreatic surgery was13.46%.In univariate analysis,the risk factors of SSI after hepatobiliary and pancreatic surgery were as follows:(1)BMI≥24 kg/m2;(2)patients with diabetes mellitus;(3)The average operation time was more than 120 minutes;(4)Intraoperative bleeding greater than 150 m L;(5)Hospital stay more than 10 days;(6)ASA Grade Ⅲ or above;(7)Grade of surgical incision;(8)Preoperative albumin level.logistic regression analysis:(1)BMI≥24 kg/m2;(3)Hospital stay more than 10days;(3)ASA classification;(4)In patients with diabetes,these items are independent risk factors for SSI.Conclusion(s): At present,the proportion of SSI after hepatobiliary and pancreatic surgery is still high,and there are many related factors affecting the occurrence of SSI.This study shows that the independent risk factors are diabetes mellitus,BMI,ASA grade Ⅲ and above.Clinical surgeons need to pay more attention to it,need multiple means,comprehensive prevention,and pay more attention to perioperative patient management.It can effectively avoid the occurrence of SSI caused by related high-risk factors.This study provides important relevant clinical basis for reducing and preventing SSI after hepatobiliary and pancreatic surgery in the future.
