肛肠疾病手术切口感染病原菌的临床分析

Clinical Analysis of Anorectal Disease Pathogen Operation Incision Infection

目的研究肛肠疾病手术切口感染(SSI)的病原菌特点。方法选择574例实施肛肠手术后切口出现感染的患者,对其感染的病原菌情况进行性菌,13.2%为革兰阳性菌,5.3%为真菌。结果通过分析,所选患者中有118例患者出现SSI,感染率为20.6%;其中76例为痔疮感染,占20.4%;24例为肛瘘感染,占20.7%;18例为肛裂感染,占20.9%。共分离出76株病原菌,阳性率为64.4%;其中81.5%为革兰阴性菌,13.2%为革兰阳性菌,5.3%为真菌。结论肛肠疾病术后切口出现感染率较高,常见的病原均为革兰阴性菌,导致SSI感染的因素主要有年龄、手术时间以及BMI等,需要对其实施积极有效的预防措施,这样能够很好的降低肛肠疾病SSI出现。

Objective To study the anorectal disease operation incision infection（SSI）of the characteristics of pathogenic bacteria. Methods 574 cases after the implementation of the anorectal surgery incision infection and the infection of pathogens of bacterial and 13.2% for gram positive bacteria,5.3% were fungi. Results Through analysis,118 cases of patients with SSI,infection rate was 20.6%,among them 76 cases of hemorrhoid infection accounted for 20.4%,24 cases with anal fistula infection,accounting for 20.7%,18 cases of anal fissure infection,accounted for 20.9% patients. A total of 76 strains of pathogenic bacteria were isolated,and the positive rate was 64.4%,81.5% of them were gram negative bacteria,13.2% were gram positive bacteria,5.3% were fungi. Conclusion Anorectal disease postoperative incision infection rate is higher,common pathogens are gram negative bacteria,age,operation time and BMI are the main factors lead to SSI infection,need for implementation of a positive and effective prevention measure. This can be very good to reduce SSI anorectal diseases appear.
