BACKGROUND
Perianal abscesses require immediate incision and drainage (I&D). However, prompt bedside drainage is controversial as it may compromise exposure and thorough anal examination.
OBJECTIVES
To examine outcomes of bedside I&D of perianal abscesses in the emergency department (ED) vs. the operating room (OR).
METHODS
We conducted a retrospective review of all patients presented to the ED with a perianal abscesses between January 2018 and March 2020. Patients with Crohn's disease, horseshoe or recurrent abscesses were excluded.
RESULTS
The study comprised 248 patients; 151 (60.89%) underwent I&D in the OR and 97 (39.11%) in the ED. Patients elected to bedside I&D had smaller abscess sizes (P = 0.01), presented with no fever, and had lower rates of inflammatory markers. The interval time from diagnosis to intervention was significantly shorter among the bedside I&D group 2.13 ± 2.34 hours vs. 10.41 ± 8.48 hours (P < 0.001). Of patients who underwent I&D in the OR, 7.3% had synchronous fistulas, whereas none at bedside had (P = 0.007). At median follow-up of 24 months, recurrence rate of abscess and fistula formation in patients treated in the ED were 11.3% and 6.2%, respectively, vs. 19.9% and 15.23% (P = 0.023, 0.006). Fever (OR 5.71, P = 0.005) and abscess size (OR 1.7, P = 0.026) at initial presentation were risk factors for late fistula formation.
CONCLUSIONS
Bedside I&D significantly shortens waiting time and does not increase the rates of long-term complications in patients with small primary perianal abscesses.

Surgery is the most important treatment for perianal abscesses. However, the gut microbiota of patients with perianal abscess and the effects of perianal abscess on the gut microbiota after surgery are unknown. In this study, significant changes in interleukin 6 and tumor necrosis factor- in the blood of healthy subjects, patients with perianal abscesses, and patients after perianal abscess surgery were identified. 16S rRNA gene sequencing technology was used to detect the changes in the gut microbiota among 30 healthy individuals and 30 patients with perianal abscess before and after surgery. Venn diagrams and alpha diversity analyses indicated differences in the abundance and uniformity of gut microbiota between the healthy individuals and patients with perianal abscesses before and after surgery. Beta diversity analysis indicated that the grouping effects among the control, abscess, and surgery groups were good. The classification and compositional analysis showed significant differences in the gut microbiota between healthy individuals and patients with perianal abscesses before and after surgery. LEfSe analysis, random forest analysis, and ROC curve analysis showed that (AUC = 0.7467) and (AUC = 0.72) could be potential biomarkers for the diagnosis of perianal abscess. The functional prediction results showed that the differential microbiota is significantly enriched in the pathways related to nutrition and drug metabolism. This study may have important implications for the clinical management and prognostic assessment of patients with perianal abscesses.

Review
Actinomycosis is a serious suppurative, bacterial infection caused by the gram-positive anaerobic Actinomyces species. Primary perianal actinomycosis is rare and challenging for the colorectal surgeon. We aimed to present our experience and compare this with available literature. All patients with isolated Actinomyces on microbiology reports, between January 2013 and February 2021, were identified and reviewed. Data collection was retrospective based on electronic patient records. The site of infection and treatment strategy were examined. Perianal cases were evaluated in depth. All publications available in the literature were interrogated. Fifty-nine cases of positive actinomycosis cultures were reviewed. Six cases of colonization were excluded. Actinomyces turicensis was the most common organism isolated. Five cases of perianal actinomycosis were identified requiring prolonged antibiotic and surgical therapy. Twenty-one studies, most case reports, published since 1951 were also reviewed. Diagnosis of perianal actinomycosis may be challenging but should be suspected particularly in recurrent cases. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium. An extended course of antibiotic therapy (months) is required for eradication in certain cases.

Meta-Analysis
BACKGROUND AND AIMS
Perianal Crohn's disease (pCD) is a potentially severe phenotype of CD. We conducted a systematic review with meta-analysis to estimate cumulative incidence, risk factors, and outcomes of pCD in population-based cohort studies.
METHODS
Through a systematic literature review through March 1, 2021, we identified population-based inception cohort studies reporting cumulative incidence of perianal disease (primarily abscess and/or fistula) in patients with CD. We estimated the cumulative incidence of pCD at presentation and 1-, 5-, and 10-year follow-up, and risk factors for perianal disease and outcomes including risk of major (bowel resection, proctectomy, ostomy) and minor perianal (incision and drainage, seton placement, etc.) surgery.
RESULTS
In 12 population-based studies, prevalence of pCD was 18.7% (95% confidence interval [CI], 12.5%-27.0%) with 1-, 5-, and 10-year risk of perianal disease being 14.3% (95% CI, 7.9%-24.6%), 17.6% (95% CI, 11.3%-26.5%), and 18.9% (95% CI, 15.0%-23.4%), respectively. Approximately 11.5% of patients (95% CI, 6.7%-19.0%) had perianal disease at or before CD diagnosis. Colonic disease location and rectal involvement were associated with higher risk of pCD. Overall, 63.3% of patients (95% CI, 53.3-72.3) required minor perianal surgery and 6.4% of patients (95% CI, 1.8%-20.6%) required major abdominal surgery for pCD. Use of biologic therapy for pCD is common and has steadily increased throughout the years.
CONCLUSIONS
Approximately 1 in 5 patients with CD develops perianal disease within 10 years of CD diagnosis, including 11.5% who have perianal disease at presentation. Approximately two-thirds of patients require perianal surgery, with a smaller fraction requiring major abdominal surgery.

Perianal abscesses are frequent diseases in general surgery. Principles of standard patient care are surgical drainage with exploration and concomitant treatment of fistula. Antiinfective therapy is frequently applied in cases of severe local disease and perianal sepsis. However, the role of microbiologic testing of purulence from perianal abscesses is disputed and the knowledge concerning bacteriology and bacterial resistances is very limited. A retrospective cohort study was performed of consecutive patients (≥ 12 years of age) from a tertiary care hospital, who underwent surgical treatment for perianal abscess from 01/2008 to 12/2019. Subdividing the cohort into three groups regarding microbiological testing results: no microbiological testing of purulence (No_Swab, n = 456), no detection of drug resistant bacteria [DR(-), n = 141] or detection of bacteria with acquired drug resistances from purulence [DR(+), n = 220]. Group comparisons were performed using Kruskall-Wallis test and, if applicable, followed by Dunn´s multiple comparisons test for continuous variables or Fishers exact or Pearson's X test for categorical data. Fistula persistence was estimated by Kaplan Meier and compared between the groups using Log rank test. Corralation analysis between perioperative outcome parameters and bacteriology was performed using Spearman´s rho rank correlation. Higher pretherapeutic C-reactive protein (p < 0.0001) and white blood cell count (p < 0.0001), higher rates of supralevatoric or pararectal abscesses (p = 0.0062) and of complicated fistula-in-ano requiring drainage procedure during index surgery (p < 0.0001) reflect more severe diseases in DR(+) patients. The necessity of antibiotic therapy (p < 0.0001), change of antibiotic regimen upon microbiologic testing results (p = 0.0001) and the rate of re-debridements during short-term follow-up (p = 0.0001) were the highest, the duration until definitive fistula repair was the longest in DR(+) patients (p = 0.0061). Escherichia coli, Bacteroides, Streptococcus and Staphylococcus species with acquired drug resistances were detected frequently. High rates of resistances against everyday antibiotics, including perioperative antibiotic prophylaxis were alarming. In conclusion, the knowledge about individual bacteriology is relevant in cases of complex and severe local disease, including locally advanced infection with extended soft tissue affection and perianal sepsis, signs of systemic inflammatory response as well as the need of re-do surgery for local debridements during short-term and fistula repair during long-term follow-up. Higher rates of acquired antibiotic resistances are to be expected in patients with more severe diseases.

PURPOSE
We aimed to evaluate the demographic characteristics of children with perianal abscess, distribution of microbiological etiology, antibiotic susceptibility, and identify the effectiveness and coverage of antibiotics due to culture results.
METHODS
A retrospective study was designed to evaluate pediatric patients with perianal abscesses between January 2013 and December 2022.
RESULTS
A total of 197 episodes in 135 patients were evaluated. The median age of the patients was 10 months (22 days-17 years). The isolated microorganisms were Gram-positive bacteria in 56 (28.4%) patients and Gram-negative bacteria in 141 (71.6%) patients. The most common isolated species was Escherichia coli (n = 70, 35.5%), followed by Klebsiella spp. (n = 48, 24.4%), Staphylococcus aureus (n = 37, 18.9%), and Enterobacter spp. (n = 9, 4.5%). Forthy-two percent (n = 58) of isolates were positive for extended-spectrum beta-lactamase, 8% (n = 11) were carbapenem-resistant in Gram-negative bacteria, and 37.5% (n = 21) were methicillin-resistant, 7.1% (n = 4) were vancomycin-resistant in Gram-positive bacteria. According to bacterial culture results, ertapenem plus glycopeptide had the highest antimicrobial coverage rate (92.3%), followed by ertapenem plus clindamycin (89.8%), ertapenem (81.7%), third-generation cephalosporin plus glycopeptide (82.2%), third-generation cephalosporin plus clindamycin (69.5%).
CONCLUSION
Ertapenem can be a good choice in the empirical treatment of perianal abscesses in children due to its high coverage rate.

American Journal of Translational... 2023This study aimed to comprehensively evaluate perianal fistulas and their related complications using magnetic resonance imaging (MRI).
OBJECTIVE
This study aimed to comprehensively evaluate perianal fistulas and their related complications using magnetic resonance imaging (MRI).
METHODS
We enrolled 115 eligible patients who underwent preoperative perianal MRI. Primary fistulas, internal and external openings, and related complications were evaluated using MRI. All fistulas were classified according to Park's classification, Standard Practice Task Force classification, St. James's grade, and the position of the internal opening.
RESULTS
In total, 169 primary fistulas were detected in 115 patients; 73 (63.5%) patients had a single primary tract and 42 (36.5%) patients had multiple primary tracts, and 198 internal and 129 external openings were identified. Based on Park's classification, 150 (88.7%) primary fistulas were classified into the following types: intersphincteric (82, 54.7%), trans-sphincteric (58, 38.6%), suprasphincteric (8, 5.3%), extrasphincteric (1, 0.7%), and diffuse intersphincteric with trans-sphincteric (1, 0.7%) types. Based on St. James's grade, 149 fistulas were classified into grade 1 (52, 34.9%), grade 2 (30, 20.1%), grade 3 (20, 13.4%), grade 4 (38, 25.5%), and grade 5 (9, 6.1%). We detected 92 (54.4%) simple and 77 (45.6%) complex perianal fistulas and 72 (42.6%) high and 97 (57.4%) low perianal fistulas. Furthermore, we detected 32 secondary tracts in 23 (20.0%) patients and 87 abscesses in 60 (52.2%) patients. Levator ani muscle involvement and extensive soft tissue edema were detected in 12 (10.4%) and 24 (20.9%) patients, respectively.
CONCLUSION
MRI is a valuable and comprehensive tool that can not only be used to determine the general condition of perianal fistulas but also to classify them and identify related complications.

Review
Hidradenitis suppurativa (HS) is a chronic, progressive, debilitating, recurrent inflammatory skin disease characterized by the occurrence of very severe, persistent, painful nodules, abscesses, and fistulas, most commonly found in the skin folds of the axilla, groin, gluteal, and perianal areas. The pathogenesis of HS is still not completely understood; currently, it is considered to be an immune-mediated inflammatory illness (IMID). Due to the significant decrease in the patients' quality of life and a delayed beginning of a treatment, the selection of the appropriate therapy is extremely important in these patients. Regardless of the fact that there are multiple treatment options for HS, no uniformly effective therapy has been found. All the guidelines underline the need for a multidisciplinary approach to the disease, which enables providers to create the right management of HS. This article aims to provide updates on the current treatment options of acne inversa to raise awareness and improve the management of the disease.

Review
Crohn disease (CD) patients can develop fistula or abscess from persistent active disease or postsurgical complications. Penetrating CD is traditionally treated with medication and surgery. The role of medication alone in the treatment of fistula is limited, except perianal fistulas or enterocutaneous fistula. Surgery is the standard treatment in those with hollow-organ to hollow-organ fistula, like ileovesicular fistula. Surgery is invasive with a higher risk of postoperative complications. Endoscopic therapy has evolved as a valid option. Fistulotomy, surgical or endoscopic, should be considered first-line therapy when feasible. Incision and drainage of perianal abscesses with an endoscopic device may be attempted.

INTRODUCTION
Perianal abscess and fistula-in-ano are common findings in infants and children. The perianal abscess is usually a manifestation of a fistula-in-ano. Experience of our center indicates general lack of knowledge of the origin of the abscess and therefore, it is usually treated by incision and drainage, which leads to repeated recurrences.
AIM
We aimed to present the optimal management of fistula-in-ano and perianal abscess in order to reduce or even eliminate the risk of recurrence.
MATERIAL AND METHODS
The retrospective study included 24 infants with perianal abscess treated at our center between 2013 and 2015. Patients were divided into two groups: group I (50%) was primary treated in our center, while group II had undergone prior surgical interventions in other hospitals. Fistula-in-ano was intraoperatively identified in all patients (100%) and fistulotomy was performed.
RESULTS
No fecal incontinence or recurrence of perianal abscess were observed in any of our patients. In group II, the disorder was associated with severe inflammation, some patients underwent an additional surgical intervention, such as incision and drainage of an extensive buttock's abscess; patients required longer antibiotic therapy and prolonged hospitalization.
CONCLUSION
Minimally invasive approach (sitz baths, antibiotic therapy, puncture or incision and drainage of the abscess) appears tempting due to its simplicity and lack of need for general anesthesia, but it is associated with a high recurrence rate. Fistulotomy and fistulectomy, which are slightly more invasive procedures, significantly reduce the recurrence rate of fistulain- ano and perianal abscess.
