BACKGROUND
Acute surgical units (ASU) are increasingly being adopted and in our system are staffed by colorectal and non-colorectal general surgeons. This study aims to evaluate whether surgeon specialization was associated with improved outcomes in perianal abscess.
METHODS
Patients with perianal abscess admitted to the ASU between 2016 and 2020 were identified from a prospective database and their medical records reviewed. Patients with IBD, treatment for fistula-in-ano within the preceding year, or perianal sepsis of non-cryptoglandular origin were excluded. Patients admitted under an ASU colorectal (CR) consultant were compared with those under a non-CR general surgeon in a retrospective cohort study. Primary outcome was perianal abscess recurrence. For those without initial fistula, hazard of recurrent abscess or fistula was analysed. Multivariable Cox PH regression analysis was performed.
RESULTS
Four-hundred and eight patients were included (150 CR, 258 non-CR). The CR group more frequently had a fistula identified at index operation (34.0% versus 10.9%, P < 0.0001). However, Cox multivariable analysis found no difference in hazard of recurrent abscess between groups (HR 1.12, 95% CI 0.65-1.95, P = 0.681)). Abscess recurred in 18.7% CR and 15.5% non-CR. Subsequent fistula developed in 14.7% in both groups. For patients without initial fistula, there was no difference between groups in hazard of recurrent abscess or fistula (HR 1.18, 95% CI 0.69-2.01, P = 0.539).
CONCLUSION
Surgeon specialization was not associated with improved outcomes for ASU patients with perianal abscess, albeit with potential selection bias. CR surgeons were more proactive identifying fistulas; this raises the possibility that drainage alone may be adequate treatment.

PURPOSE
The features of perianal abscess and fistula-in-ano in infants are different from those of older children, and there is controversy regarding their treatment. The aim of this study was to assess the efficacy of various methods used for their management.
METHODS
A retrospective analysis of the records was conducted for all infants younger than 24 months of age treated for perianal abscess, fistula-in-ano, or both from 1990 to 2002.
RESULTS
The study included 98 infants. Perianal abscess was found in 77 patients (75 males), and fistula-in-ano in 21. No infant had an underlying illness. Drainage was performed by needle aspiration in 47 patients and by incision and drainage in 5. Following drainage, 43 patients received antibiotics. Altogether, 6 infants were treated with antibiotics alone and 19 with local care alone. Twenty-eight boys (36.4 percent) had an evolution toward fistula-in-ano. Patients who received antibiotics following drainage were less likely to develop fistula-in-ano than were patients who underwent a drainage procedure alone (27.9 percent vs. 66.7 percent, P < 0.05). All patients with fistula-in-ano were male and had been previously treated for perianal abscess (21 patients elsewhere and 28 in our department). Spontaneous cure of fistula-in-ano occurred in 42.9 percent of them (average 3.2 months), and 57.1 percent underwent fistulectomy for persistent fistula-in-ano. Cryptotomy was added when an involved crypt was found (11 patients, 39.3 percent). No recurrence of fistula-in-ano was noted after fistulectomy.
CONCLUSIONS
Local treatment for perianal abscess during the early stage and drainage by needle aspiration during the progressive stage are effective. Antibiotics may be considered for patients undergoing drainage of perianal abscess. Fistula-in-ano can be managed conservatively for one to three months. For a persisting fistula, fistulectomy with cryptotomy (when abnormal anal crypts are found) is the preferred treatment.

Review
Anorectal abscesses and fistulas are seen commonly in the primary care practice. An abscess forms as the result of obstruction of an anal gland, with resulting retrograde infection. An anal fistula simply represents the chronic phase of a perianal abscess. The history generally is diagnostic, and special studies usually are not required. Treatment is surgical, with good results.

ANZ Journal of Surgery Mar 2019To investigate the role of interleukin (IL)-17 in tissue and peripheral blood of perianal abscess and anal fistula.
BACKGROUND
To investigate the role of interleukin (IL)-17 in tissue and peripheral blood of perianal abscess and anal fistula.
METHODS
Patients with primary perianal abscess (n = 50) admitted to Jinhua Municipal Central Hospital between March 2003 and August 2004 were enrolled. Fifty patients with mixed haemorrhoids, who showed no perianal abscess or anal fistula, were also recruited as the control. After surgery, patients were followed up for 6 months. Protein and gene expression of IL-17 was determined in surgically harvested anal tissues and peripheral blood, respectively. The relationship between IL-17 and clinical pathological features were analysed.
RESULTS
As shown by immunohistochemistry of anorectal tissues, the positive rate of IL-17 protein was higher in the perianal abscess group than in the control group. In patients with perianal abscess, the expression of IL-17 significantly correlated with the diameter of the abscess (P = 0.013), the wound surface healing time (P = 0.010) and the progression into anal fistula (P = 0.003). For the gene expression of IL-17 in peripheral blood cells, the level was significantly higher in patients with perianal abscess comparing to the control group (0.4350 ± 0.1190 versus 0.1785 ± 0.1230, P ≤ 0.001). Comparing to the recovery group, patients with their perianal abscess progressed to anal fistula showed higher levels of IL-17 gene expression (P = 0.014).
CONCLUSIONS
Expression of IL-17 was increased in the anorectal tissues and peripheral blood of patients with perianal abscess and anal fistula. IL-17 may play an important role in the pathogenesis of perianal abscess and anal fistula.

Diagnosis and Clinical Features of Perianal Lesions in Newly Diagnosed Crohn's Disease: Subgroup Analysis from Inception Cohort Registry Study of Patients with Crohn's Disease (iCREST-CD).
BACKGROUND AND AIMS
Perianal lesion is a refractory phenotype of Crohn's disease [CD] with significantly diminished quality of life. We evaluated the clinical characteristics of perianal lesions in newly diagnosed CD patients and the impact of perianal lesions on the quality of life in Japanese patients with CD.
METHODS
Patients newly diagnosed with CD after June 2016 were included between December 2018 and June 2020 from the Inception Cohort Registry Study of Patients with CD [iCREST-CD].
RESULTS
Perianal lesions were present in 324 [48.2%] of 672 patients with newly diagnosed CD; 71.9% [233/324] were male. The prevalence of perianal lesions was higher in patients aged <40 years vs ≥40 years, and it decreased with age. Perianal fistula [59.9%] and abscess [30.6%] were the most common perianal lesions. In multivariate analyses, male sex, age <40 years and ileocolonic disease location were significantly associated with a high prevalence of perianal lesions, whereas stricturing behaviour and alcohol intake were associated with low prevalence. Fatigue was more frequent [33.3% vs 21.6%] while work productivity and activity impairment-work time missed [36.3% vs 29.5%] and activity impairment [51.9% vs 41.1%] were numerically higher in patients with than those without perianal lesions.
CONCLUSIONS
At the time of CD diagnosis, approximately half of the patients had perianal lesions; perianal abscesses and perianal fistulas were the most common. Young age, male sex, disease location and behaviour were significantly associated with the presence of perianal lesions. The presence of perianal lesion was associated with fatigue and impairment of daily activities.

Review
Endoanal ultrasound is a technique that provides imaging of the anal sphincters and its surrounding structures as well as the pelvic floor. However, endoanal magnetic resonance imaging (MRI) is preferred by most physicians, although costs are higher and demand easily outgrows availability. Endoanal ultrasound is an accurate imaging modality delineating anatomy of both cryptoglandular as well as Crohn perianal fistula and abscess. Endoanal ultrasound is comparable with examination under anesthesia and equally sensitive as endoanal MRI in fistula detection. When fistula tracts or abscesses are located above the puborectal muscle, an additional endoanal MRI should be performed. Preoperative imaging is advocated in recurrent cryptoglandular fistula because a more complex pattern can be expected. Endoanal ultrasound can help avoid missing tracts during surgery, lowering the chance for the fistula to persist or recur. It can easily be performed in an outpatient setting and endosonographic skills are quickly incremented. Costs are low and endoanal ultrasound has the potential to improve outcome of patients with both cryptoglandular and fistulizing Crohn disease; therefore, it values more attention.

The authors present a retrospective review of 40 pediatric patients with perianal abscess and/or fistula-in-ano. The total patient population could be divided clinically into 2 broad groups. The first group consisted of 22 infants younger than 2 years of age, all of whom were males, and 10 of whom presented with recurrences after previous incision and drainage. Of the 14 infants presenting with an abscess, in 12 (85.7 percent), a fistula-in-ano was discovered at surgery. In contrast, in the group of 18 children older than 2 years of age, there were 7 females and 11 males, and fistulas were identified in only 7 of 13 patients (54.8 percent) who presented with abscesses. Surgical treatment consisted of examination under anesthesia and a diligent search for a fistulous tract. Abscesses were primarily saucerized and fistulotomy and cryptotomy of the confluent crypt was performed if a fistulous tract was identified. The only recurrences with this form of treatment occurred in the two immunocompromised patients.

Review
Pediatric inflammatory bowel disease is a chronic gastrointestinal disease consisting of Crohn's disease (CD) and ulcerative colitis (UC). Both disease processes can share similar clinical symptoms including abdominal pain, diarrhea, hematochezia, and weight loss; CD can also be complicated by penetrating and fistulizing disease. Perianal skin tags, perianal abscesses, recto-cutaneous fistulae, and rectal stenosis are among the phenotypic characteristics of perianal CD. Current treatment strategies are focused on the surgical drainage of abscesses and the closure of fistulous tracts as well as controlling intestinal inflammation with the use of immunomodulators (6-mercaptopurine and methotrexate) and biologics (infliximab and adalimumab). Current guidelines by the American Gastroenterology Association and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition recommend a combination of surgical intervention and medical management for the treatment of perianal CD.

INTRODUCTION
Perianal fistula is a burdening disease with an annual incidence of 6-12/100 000 in Western countries. More than 90% of crypto-glandular fistulas originate from perianal abscess. Despite adequate drainage, up to 83% recur or result in an anal fistula, the majority developing within 12 months. There is some evidence that gut-derived bacteria play a role in the development of perianal fistula. Up till now, it is not common practice to routinely administer prophylactic antibiotics to prevent anal fistula development. There is a need for a study to establish whether adding antibiotic treatment to surgical drainage of perianal abscess results in a reduction in perianal fistulas.
METHODS AND ANALYSIS
This multicentre, double-blind, randomised, placebo-controlled trial investigates whether addition of antibiotics (ciprofloxacin and metronidazole) to surgical drainage of a perianal abscess is beneficial compared with surgical drainage alone. The primary outcome is the development of a perianal fistula within 1 year. Secondary outcomes include quality of life, treatment costs, need for repeated drainage, patient-reported outcomes and other clinical outcomes. Participants are recruited in one academic and seven peripheral Dutch clinics. To demonstrate a reduction of perianal fistula from 30% to 15% when treated with adjuvant antibiotics with a two-sided alpha of 0.05, a power of 80% and taking a 10% loss to follow-up percentage into account, the total sample size will be 298 participants. Data will be analysed according to the intention-to-treat principle.
ETHICS AND DISSEMINATION
The study protocol has been approved by the Medical Ethics Review Committee of the Amsterdam University Medical Centers (nr. 2021_010). Written consent is obtained from each participant prior to randomisation into the study. The results of this trial will be submitted for publication in international peer-reviewed journals, presented at conferences and spread to coloproctological associations.
