Epidemiological investigation and analysis on perianal surgical site infection in patients with anorectal diseases in Wuhan FREE

摘要:

目的在建立《肛肠疾病肛周手术部位医院感染诊断标准》的基础上，对武汉市肛肠疾病肛周手术部位感染的情况进行流行病学调查与分析。方法采用流行病学前瞻性调查方法，在武汉市不同规模的5家医院调查、收集资料，对肛肠疾病住院患者术后手术部位感染的相关因素：年龄、性别、职业、体型、既往病症、手术持续时间、麻醉方式、切口部位（包括肛周）菌种与菌量变化、住院时间与费用等进行流行病学分析，并以新建的“诊断标准”对总的感染情况进行判断、评估。结果武汉市肛肠疾病肛周手术部位总的感染率为32.98％（124/376），其中痔疮等疾病（包括内/外痔、混合痔、直肠息肉、肛裂）手术部位感染率为29.06％（77/265），肛周脓肿手术部位感染率为38.46％（15/39），肛瘘手术部位感染率为44.44％（32/72）。经统计学分析，肛肠疾病肛周手术部位感染与患者的住院时间有关（P<0.05）；肛周手术部位微生物的菌量和菌种在手术后分别有24.50%、30.46%发生变化。结论通过本次调查，首次得到了武汉市常见肛肠疾病肛周手术部位感染情况的流行病学资料，为常见肛肠疾病肛周手术部位感染的预防和控制提供了科学依据。
 

Abstract:

ObjectiveTo investigate the incidence of perianal surgical site infection（SSI）in patients with anorectal diseases in hospitals in Wuhan on the basis of “The diagnostic criteria for perianal SSI in anorectal diseases”. MethodsEpidemiological prospective survey was adopted, five  hospitals in Wuhan were selected to collect information, the relevant factors for perianal SSI, including age, sex, occupation, obesity, history of diseases, duration of operation, anaesthesia, change in the number and species of bacteria at incisional site（including perianal）, and hospitalization time and costs were analysed, SSI was evaluated according to the newly established “diagnostic criteria”. ResultsThe overall rate of perianal SSI in anorectal diseases was 32.98 %（124/376）. SSI in hemorrhoid (including internal and external hemorrhoid, mixed hemorrhoid, rectal polyp,and anal fissure) was 29.06％（77/265）, SSI in perianal abscess and  anal fistula was 38.46％（15/39） and 44.44％（32/72）respectively.Statistical analysis showed that perianal SSI was relevant to patients’ hospital stay （P<0.05）, the percentage of changes in the number and species of bacteria at surgical sites was 24.50% and 30.46% respectively.ConclusionThis survey acquired the epidemiological data about perianal SSI in patients with anorectal diseases in Wuhan, which provide the scientific basis to prevent and control perianal SSI in anorectal diseases.
