METHODS: This retrospective study included all patients aged 18 or older who underwent surgical incision and drainage for perianal abscess in a single medical center between 2016 and 2020. Data regarding demographics, bacteriological cultures, and length of hospital stay were collected via electronic patient charts. A prolonged hospital stay was defined as a LOS longer than 3 days.
RESULTS: A total of 791 patients were included, of which 77.5% were male, with a mean age of 43.2. Overall, 46.1% of patients had positive cultures, of which 69.9% were polymicrobial. The most common pathogen found in obtained cultures was Escherichia coli (69.9%), followed by streptococcus species (36.7%) and Bacteroides (26.0%). Females had a significantly longer hospital stay (p = 0.03). Prolonged hospital stay was associated with older age (p < 0.0001), female gender (p = 0.04), and positive cultures for Enterococcus (p = 0.02).
CONCLUSIONS: This study identified clinical and microbiological risk factors for prolonged hospitalization in patients with perianal abscesses. Further studies are needed to evaluate the association between specific pathogens and rates of complications.
方法:这项回顾性研究包括2016年至2020年在一个医疗中心接受肛周脓肿手术切开引流术的所有18岁或以上患者。有关人口统计的数据,细菌学培养,和住院时间是通过电子病人图表收集的。长期住院定义为LOS超过3天。
结果:共纳入791例患者,其中77.5%为男性,平均年龄43.2岁.总的来说,46.1%的患者有阳性培养,其中69.9%为多微生物。在获得的培养物中发现的最常见的病原体是大肠杆菌(69.9%),其次是链球菌(36.7)和拟杆菌(26.0%)。女性的住院时间明显更长(p=0.03)。住院时间延长与年龄较大有关(p<0.0001),女性(p=0.04),和肠球菌阳性培养物(p=0.02)。
结论:本研究确定了肛周脓肿患者长期住院的临床和微生物学危险因素。需要进一步的研究来评估特定病原体与并发症发生率之间的关系。
