Abstract
BACKGROUND Accurate tools to distinguish Crohn's disease [CD] from cryptoglandular disease in patients with perianal fistulas without detectable luminal inflammation on ileocolonoscopy and abdominal enterography (isolated perianal fistulas [IPF]) are lacking. We assessed the ability of video capsule endoscopy [VCE] to detect luminal inflammation in patients with IPF. METHODS We studied consecutive adults [>17 years] with IPF who were evaluated by VCE after a negative ileocolonoscopy and abdominal enterography between 2013 and 2022. We defined luminal CD by VCE as diffuse erythema, three or more aphthous ulcers, or a Lewis score greater than 135. We compared rates of intestinal inflammation in this cohort with age- and sex-matched controls without perianal fistulas, who underwent VCE for other indications. We excluded persons with pre-existing inflammatory bowel disease [IBD] and exposure to non-steroidal anti-inflammatory drugs or immunosuppressive treatments. RESULTS A total of 45 patients with IPF underwent VCE without complications. Twelve patients [26%] met our definition of luminal CD. Luminal CD was more common in patients with IPF than in controls [26% vs 3%; p <0.01]. Among patients with IPF, male sex (OR [odds ratio], 9.2; 95% confidence interval [CI] [1.1-79.4]), smoking (OR, 4.5; 95% CI [0.9-21.2]), abscess (OR, 6.3; 95% CI [1.5-26.8]), rectal enhancement on magnetic resonance imaging [MRI] (OR, 9.0; 95% CI [0.8-99.3]), and positive antimicrobial serology (OR, 7.1; 95% CI, [0.7-70.0]) were more common in those with a positive VCE study. CONCLUSIONS VCE detected small intestinal inflammation suggestive of luminal CD in approximately one-quarter of patients with IPF. Larger studies are required to validate these findings.

Abstract
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-α 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 Klebsiella (AUC = 0.7467) and Bilophila (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.

Abstract
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. TRIAL REGISTRATION NUMBERS 2020-004449-35; NCT05385887.

Abstract
BackgroundThe internal orifice plays an important role in the pathogenesis and treatment of the most complex fistula-in-ano. The treatment of the internal orifice is considered to be the key to the success of anal fistula surgery. The objective of this study is to evaluate the feasibility of a new sphincter-sparing surgical approach for anal fistula.Materials and MethodsAll hospitalized anal fistula patients were included in this study. Preoperative anorectal ultrasound was done on all the patients. Transanal internal orifice alloy closure (IOAC) was performed through a disposable titanium nickel alloy anal fistula stapler. The external sphincter was not cut. An anal fistula brush was used to curette and clean fistulas. Postoperative anorectal color ultrasound was used for evaluation 2 months postoperatively.ResultsTwenty-one patients (male/female: 18/3, age: 39.7 ± 10.5 years) with fistula-in-ano were included (follow-up: 6–11 months).In total, 38.1% (8) had multiple tracts, and 9.5% (2) belonged to a high anal fistula. In total, 23.8% (5) of anal fistula patients were complicated by Crohn’s disease. The fistula healed completely in 85.7% (18/21) and did not heal in 14.3% (3/21). Three patients who did not heal had conventional surgery reperformed and eventually healed. Except for three patients undergoing additional traditional anal fistula surgery, the Wexner incontinence scores of other patients did not change after surgery compared with before surgery.ConclusionsIOAC is a novel sphincter-saving technique that is simply effective in treating anal fistula containing Crohn’s anal fistula.

Abstract
BACKGROUND Video-Assisted Anal Fistula Treatment (VAAFT) is a novel minimally invasive & sphincter-saving technique for treating complex fistula-in-ano involving endoscopic assessment & treatment of perianal fistula. This retrospective, non-randomized, observational study is the first Australian study of VAAFT. It is also the longest study of VAAFT to-date. METHODS From January 2014 to September 2019, 59 patients with a complex anal fistula were identified via MRI & underwent VAAFT. Fourteen patients had undergone previous definitive surgery for anal fistula. Specialized Karl Storz video equipment (fistuloscope) was used in the procedure. The rigid fistuloscope was used to directly visualize the fistula tract/s & internal opening. Closure of the internal opening was then performed. The fistula tract/s were then treated via fulguration. The external opening was kept patent & dressed. Patients were then followed up for a mean 59.5 months. RESULTS 67.9% (n = 38) of patients achieved primary healing (needing nil further intervention) at a median of 13 weeks. 12.5% (n = 7) experienced healing followed by recurrence while 19.6% (n = 11) experienced non-healing. Of the recurrence/non-healing groups, 11/18 underwent repeat VAAFT with healing occurring in 10/11 patients at a median of 7 weeks. The mean operating time was 41.1 min. There were no major complications & continence scores were not affected. Three patients were lost to follow up. CONCLUSION VAAFT is both effective & safe for the treatment of complex fistula-in-ano. Its minimally invasive nature means that in the instance of recurrence or persistence, VAAFT can be repeated with minimal morbidity & reasonable likelihood of success.

Abstract
Anal fistulae are abnormal hollow connections between the wall of the anal canal and the perianal skin around the anus that have remained a burden on the medical sector for centuries. The complexity of this disease is attributed to a number of factors such as the degree of associated sphincter muscle, concomitant illnesses, existence of multiple fistulous tracts and the number of previous interventions. Persistence of a complex anal fistula can cause a decline in patient's physical quality of life as well as impact on the psychological status of patients who often suffer from anxiety and depression. Surgical intervention remains the gold standard for treatment, however; the risk of incontinence and high recurrence potential has led to interest into developing alternative treatment approaches such as the use of biologics, bioactives and biomaterials. One potential reason for these varied outcomes could be the multifactorial interplay between genetic, immune-related, environmental, and microbial persistence factors on tissue regeneration. Recent observations have proposed that adverse inflammatory mediators may contribute more than microbial factors. The moderate to high success rates of biotechnological advances (mesenchymal stem cells and biomaterial scaffolds) show promise as therapies for the amelioration of adverse persistent factors while facilitating a means to closing the fistula tract. The purpose of this review is to outline recent advances in biologics and combination therapies to treat persistent factors associated with complex anal fistula.

Abstract
AIM Fistula-in-ano (FIA) is associated with high treatment costs and has a deleterious impact on quality of life. A wide range of healing, incontinence and recurrence rates have been reported. This study aimed to identify operative, patient and disease factors that influence these outcomes after surgery for FIA. METHOD An observational cohort study of consecutive patients who were managed for FIA at a tertiary colorectal practice (1999-2019) was performed. Outcome measures included healing, impaired continence and the need to reoperate. Clinico-pathological variables, including patient comorbidities, fistula anatomy and operative approach, were assessed for their association with these outcomes. RESULTS Some 411 procedures were performed on 263 patients [median age 41.8 years (range 17.8-79.7 years), 184 men (70.0%)]. Some 77.9% of patients achieved complete healing, 9.5% experienced some deterioration in continence postoperatively and 37.6% required reoperation at a median time of 19.0 weeks. Poorer healing was associated with Crohn's disease, high trans-sphincteric fistulas, extrasphincteric fistulas and steroid usage. Poorer continence was associated with female sex, age > 40 years, posterior location, suprasphincteric fistulas, seton insertion and having more than three subsequent procedures. The need to reoperate was associated with female sex, high trans-sphincteric fistulas, suprasphincteric fistulas, inflammatory bowel disease and previous operations for FIA. CONCLUSION Minimizing recurrence of FIA and preservation of continence can be competing management goals. More than one in three patients require reoperation, one in five fails to heal completely and one in ten suffers worsened continence following surgery. Awareness of the factors that contribute to these outcomes is important to the process of informed consent and managing patient expectations before surgery.

Abstract
BACKGROUND The number of citations a scientific paper has received indicates its impact within any medical field. We performed a bibliometric analysis to highlight the key topics of the most frequently cited 100 articles on perianal fistula to determine the advances in this field. METHODS The Scopus database was searched from 1960 to 2018 using the search terms "perianal fistula" or "anal fistula" or "fistula in ano" or "anal fistulae" or "anorectal fistulae" including full articles. The topic, year of publication, publishing journal, country of origin, institution, and department of the first author were analyzed. RESULTS The median number of citations for the top 100 of 3431 eligible papers, ranked in order of the number of citations, was 100 (range: 65-811), and the number of citations per year was 7.5 (range: 3.8-40.1). The most-cited paper (by Parks et al in 1976; 811citations) focused on the classification of perianal fistula. The institution with the highest number of publications was St Mark's Hospital, London, UK. The most-studied topic was surgical management (n = 47). The country and the decade with the greatest number of publications in this field were the USA (n = 34) and the 2000s (n = 50), respectively. CONCLUSION The 100 most frequently cited manuscripts showed that surgical management had the greatest impact on the study of perianal fistula. This citation analysis provides a reference of what could be considered the most classic papers on perianal fistula, and may serve as a reference for researchers and clinicians as to what constitutes a citable paper in this field.

Abstract
The ideal intervention in the treatment of perianal fistula prevents the onset of infection to speed healing and prevent fistula recurrence while maintaining the function of the anal sphincter. Currently, there is no consensus on the best recommended surgical technique for perianal fistula management. Several studies have shown that fistulotomy was an easy and safe procedure for treatment of perianal fistula. Lateral internal sphincterotomy is the usual procedure performed on an anal fissure to decrease the anal sphincter tone. This study reports a combination of fistulotomy and contralateral internal sphincterotomy procedures for recurrent and complex perianal fistula to prevent recurrence. Here, we report 5 cases of recurrent and complex perianal fistula. The combination of fistulotomy and contralateral internal sphincterotomy is a relatively easy and safe procedure for complex perianal fistulae. In our cases, we found neither recurrence nor postoperative anal incontinence.

Abstract
Background Several studies have investigated the association between smoking and anal abscess and anal fistula (AA/F) diseases. However, the relationship between cigarette smoking and AA/F remains unclear. This study sought to assess the role of smoking in anorectal male patients in a Chinese population. Methods In this retrospective study, a questionnaire, including smoking history, was completed over a 3-month period by male inpatients in the Proctology Department of China-Japan Friendship Hospital. "Cases" were patients who had AA/F, and "controls" were patients with other anorectal complaints. Mann-Whitney U-test and Chi-square test were carried out to examine differences in baseline characteristics between groups. Subsequently, multivariate logistic regression was used to explore any related factors. Results A total of 977 patients aged from 18 to 80 years were included, excluding those diagnosed with inflammatory bowel disease or diabetes mellitus. Out of this total, 805 patients (82.4%) completed the entire questionnaire. Among the 805 patients, 334 (41.5%) were cases and 471 (58.5%) were controls. Results showed significant differences between cases and controls (χ2 = 205.2, P < 0.001), with smoking found to be associated with the development of AA/F diseases (odds ratio: 12.331, 95% confidence interval: 8.364-18.179, P < 0.001). Conclusions This study suggested smoking to be a potential risk factor for the development of AA/F diseases in a Chinese population. Consequently, current smoking patients should be informed of this relationship, and further research should be conducted to explore and investigate this further.

Abstract
Wound healing is the main problem in the therapy of anal fistula (AF). Daphne genkwa root has been traditionally used as an agent to soak sutures in operation of AF patients, but its function in wound healing remains largely unclear. The aim of the present study was to illuminate mechanisms of D. genkwa root treatment on AF. In the present study, 60 AF patients after surgery were randomly divided into two groups, external applied with or without the D. genkwa extractive. Wound healing times were compared and granulation tissues were collected. In vitro, we constructed damaged human skin fibroblasts (HSFs) with the treatment of TNF-α (10 μg/ml). Cell Count Kit-8 (CCK-8) and flow cytometry analysis were used to determine the effects of D. genkwa root extractive on cell viability, cell cycle and apoptosis of damaged HSFs. Furthermore, protein levels of TGF-β, COL1A1, COL3A1, Timp-1, matrix metalloproteinase (MMP)-3 (MMP-3) and MEK/ERK signalling pathways were investigated both in vivo and in vitro Results showed that D. genkwa root extractive greatly shortens the wound healing time in AF patients. In granulation tissues and HSFs, treatment with the extractive significantly elevated the expressions of COL1A1, COL3A1, Timp-1, c-fos and Cyclin D1, while reduced the expression of MMP-3 Further detection presented that MEK/ERK signalling was activated after the stimulation of extractive in HSFs. Our study demonstrated that extractive from D. genkwa root could effectively improve wound healing in patients with AF via the up-regulation of fibroblast proliferation and expressions of COL1A1 and COL3A1.
