Review
Perianal Crohn's is a common manifestation of Crohn's disease. Primary manifestations of perianal disease mirror common anorectal conditions, however treatment is less successful than in those patients without Crohn's related perianal disease. A multimodal approach to therapy including medical and surgical modalities is often necessary. The goal of treatment is to manage symptoms while maintaining continence.

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
Perianal abscess and anal fistula are 2 common anorectal diseases in infants and young children. However, their causes, clinical diagnosis, and treatment remain controversial. Compared to adults, infants with these 2 diseases exhibit unique clinical characteristics. Blind pursuit of conservative treatment or surgery may worsen the condition, resulting in increased pain in young patients and greater economic burden and psychological harm to parents. Therefore, it is crucial to select correct and effective treatments. This review summarizes the relevant literature from the past 10 years and systematically explains the pathogenesis, clinical characteristics, and treatment measures of perianal abscess and anal fistula in infants with the goal of providing clinicians a deeper understanding of perianal abscess and anal fistula in infants and summarizing safe and effective treatment methods.

Review
Crohn's disease is a chronic inflammatory disease which may involve any segment of the gastrointestinal tract, most frequently the terminal ileum, the large intestine, and the perianal region. The symptoms of perianal Crohn's disease include skin disorders, hemorrhoids, anal ulcers, anorectal stenosis, perianal abscesses and fistulas, rectovaginal fistulas and carcinoma of the perianal region. The perianal manifestations of Crohn's disease cause great discomfort to the patient and are among the most difficult aspects to treat. Management of perianal disease requires a combination of different imaging modalities and a close cooperation between gastroenterologists and dedicated surgeons.

Comparative Study Meta-Analysis Review
Transperineal ultrasound (TPUS) is a practical tool for assessing perianal inflammatory lesions. We systematically review its accuracy for detecting and classifying perianal fistulae and abscesses. The National Library of Medicine and Embase were searched for articles on TPUS for the assessment of idiopathic and Crohn's perianal fistulae and abscesses. Two reviewers independently reviewed eligible studies and rated them for quality using the QUADAS tool. The primary outcome measure was the accuracy of TPUS as measured by its sensitivity and positive predictive value (PPV) in detecting and classifying perianal fistulae, internal openings and perianal abscesses. We included 12 studies (565 patients). Overall, the methodological quality of the studies was suboptimal. 3 studies were retrospective and 4 showed significant risks of bias in the application of the reference standard. The sensitivity of TPUS in detecting perianal fistulae on a per-lesion basis was 98 % (95 % CI 96 - 100 %) and the PPV was 95 % (95 % CI 90 - 98 %). The detection of internal openings had a sensitivity of 91 % (95 % CI 84 - 97 %) with a PPV of 87 % (95 % CI 76 - 95 %). The classification of fistulae yielded a sensitivity of 92 % (95 % CI 85 - 97 %) and a PPV of 92 % (95 % CI 83 - 98 %). TPUS had a sensitivity of 86 % (95 % CI 67 - 99 %) and PPV of 90 % (95 % CI 76 - 99 %) in the detection of perianal abscesses. The current literature on TPUS illustrates good overall accuracy in the assessment of perianal fistulae and abscesses. However, many studies had methodological flaws suggesting that further research is required.

Meta-Analysis
BACKGROUND
Perianal abscesses and anal fistulas are common. The principle of intention-to-treat has not been considered in previous systemic reviews. Thus, the comparison between primary and post-recurrence management was confused, and the recommendation of primary treatment is obscure. The current study aims to identify the optimal initial treatment for pediatric patients.
METHODS
Using PRISMA guidelines, studies were identified from MEDLINE, EMBASE, PubMed, Cochrane Library, and Google Scholar without any language or study design restriction. The inclusion criteria include original articles or articles with original data, studies of management for a perianal abscess with or without anal fistula, and patient age of <18 years. Patients with local malignancy, Crohn's disease, or other underlying predisposing conditions were excluded. Studies without analyzing recurrence, case series of <5, and irrelevant articles were excluded in the screening stage. Of the 124 screened articles, 14 articles had no full texts or detailed information. Articles written in a language other than English or Mandarin were translated by Google Translation first and confirmed with native speakers. After the eligibility process, studies that compared identified primary managements were then included in the qualitative synthesis.
RESULTS
Thirty-one studies involving 2507 pediatric patients met the inclusion criteria. The study design consisted of two prospective case series of 47 patients and retrospective cohort studies. No randomized control trials were identified. Meta-analyses for recurrence after initial management were performed with a random-effects model. Conservative treatment and drainage revealed no difference (Odds ratio [OR], 1.222; 95% Confidential interval [CI]: 0.615-2.427, p = 0.567). Conservative management had a higher risk of recurrence than surgery without statistical significance (OR 0.278, 95% CI: 0.109-0.707, p = 0.007). Compared with incision/drainage, surgery can prevent recurrence remarkably (OR 4.360, 95% CI: 1.761-10.792, p = 0.001). Subgroup analysis of different approaches within conservative treatment and operation was not performed for lacking information.
CONCLUSION
Strong recommendations cannot be made due to the lack of prospective or randomized controlled studies. However, the current study based on real primary management supports initial surgical intervention for pediatric patients with perianal abscesses and anal fistula to prevent recurrence.

BACKGROUND
The optimal management of perianal abscess in neonates and infants remains unclear, including the need for laying open of the fistula and the role of microscopy and culture studies (MCS). We aimed to report the recurrence rate following incision and drainage alone (I&D) compared to incision and drainage with laying open of the fistula (I&DF) and to determine the value of MCS in perianal abscess management.
METHODS
Following ethical approval (16326Q), a 10-year (2007-2017) review of children younger than 1 year presenting with a perianal abscess was performed. Presence of a fistula was sought in all patients. Data are presented as number of cases (%), median (range) and analysed using Fisher's exact test and Mann-Whitney U-test. P-values of <0.05 were considered significant.
RESULTS
We identified 108 patients (107 (99.1%) males) with 111 abscesses (three bilateral); 26 in I&D group and 85 in I&DF group. Initial abscess occurred to the right of midline in 64 cases (58%) and to the left of midline in 47 cases (42%). Twenty-two (20%) recurred after 30 (6-372) days. Sixty-five (59%) had MCS performed. Recurrence was higher in I&D group (9/26) versus I&DF group (13/85) (P = 0.04 (relative risk 2.2, 95% confidence interval 1.0-4.5)). There was no difference in recurrence within each group between patients with or without MCS (I&D group, P = 0.1; I&DF group, P = 0.3).
CONCLUSION
The recurrence of surgically managed perianal abscess is lower when a fistula is identified and laid open at the initial operation. There is little value of MCS in the management of paediatric perianal abscess.

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.

Review
BACKGROUND
Anorectal abscess and fistula-in-ano is a rare disease with an exemplary prognosis. Most patients are diagnosed with cryptoglandular disease but unusual infections raise difficult antimicrobial management challenges.
METHODS
All primary references identified in PubMed, EMBASE, the ISI Web of Knowledge database and the Cochrane Library, published between 1960 and 2015, using the keywords "anorectal abscess," "fistula-in-ano," "perianal abscess," or "perianal fistula" or all, were uploaded into a database. The databases were also interrogated using keywords specific for each infection type studied.
RESULTS
In all, 52 relevant primary medical publications were identified. There were also 4 relevant organizational standards guideline publications, 1 relevant review and 4 historical publications about the diagnosis and outcomes of anorectal abscess and fistula-in-ano with data derived primarily from prospective and retrospective trials as well as institutional case series to provide an evidence level opinion. The use of antimicrobial therapy in combination with surgical incision and drainage in the treatment of cryptoglandular disease has failed to improved healing times or reduce recurrences or both. Based on limited data, routine antimicrobial therapy may benefit patients with significant comorbid conditions, extensive cellulitis and systemic symptoms. For patients with unusual infecting pathogens (eg, Mycobacterium tuberculosis, Actinomyces species and Chlamydia species) outcomes are favorable with selected antimicrobial therapy agents of various durations.
CONCLUSION
Surgical incision and drainage is the main treatment for anorectal abscess and fistula-in-ano, but a select group of patients with unusual infections benefit from tailored prolonged antimicrobial therapy with the overall recurrence rate remaining low.

Review
Perianal penetrating complications of Crohn disease are among the most important causes of symptoms in the pediatric population. High-quality diagnostic imaging of the perianal region is crucial for treatment planning and therapeutic response assessment. MRI, with its absence of ionizing radiation and high soft-tissue resolution, provides an excellent noninvasive tool for evaluation of perianal fistulae and associated abscesses, as well as their anatomical relationship to the anal sphincter complex. In this review we discuss the role of MRI in initial diagnosis and follow-up of perianal fistulizing Crohn disease in the pediatric population.
