Background:
Perianal abscess is a common disease among adults, necessitating surgical drainage. We aimed to assess the role of microbiology and other factors in prolonged hospitalization of patients with perianal abscesses.
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.
Insights
Older age, female gender, and Enterococcus infections are linked to longer hospital stays for perianal abscess patients. Understanding these factors can improve care for this common condition.
Area of Science:
- Colorectal surgery
- Infectious disease epidemiology
Background:
- Perianal abscess is a frequent condition in adults requiring surgical intervention.
- Identifying factors influencing hospital stay duration is crucial for patient management.
Purpose of the Study:
- To investigate the microbiological and clinical predictors of prolonged hospitalization following perianal abscess drainage.
- To assess the impact of patient demographics and specific pathogens on length of stay (LOS).
Main Methods:
- Retrospective analysis of 791 adult patients undergoing incision and drainage for perianal abscess (2016-2020).
- Data collected included demographics, bacteriological cultures, and LOS.
- Prolonged hospital stay was defined as LOS > 3 days.
Main Results:
- Positive cultures were found in 46.1% of patients, with polymicrobial infections common (69.9%).
- Escherichia coli was the most frequent pathogen, followed by Streptococcus and Bacteroides species.
- Prolonged LOS was significantly associated with older age, female gender, and positive Enterococcus cultures.
Conclusions:
- Clinical factors (older age, female gender) and microbiological findings (Enterococcus) are associated with prolonged hospitalization for perianal abscess.
- Further research is warranted to explore the relationship between specific pathogens and complication rates.
