Abstract
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.

Abstract
BACKGROUND MR-enterography/enteroclysis (MRE) is increasingly used for primary diagnosis, detection of complications, and monitoring of patients with inflammatory bowel disease (IBD). Standardization of reporting is relevant to ensure quality of the methodology and to improve communication between different faculties. The current manuscript describes the features that are required for optimized reporting of MRE in IBD. METHODS An expert consensus panel of radiologists and gastroenterologists conducted a systematic search of the literature. In a Delphi process, members of the German Radiological Society (DRG) and members of the Competence Network for Inflammatory Bowel Diseases voted on relevant criteria for the reporting of findings in MRE. Based on the voting results, statements were developed by the expert consensus panel. RESULTS Clinically relevant aspects of MRE findings have been defined to optimize reporting and to standardize terminology. Minimal requirements for standardized reporting are suggested. The statements focus on the description of disease activity as well as on complications of IBD. Attributes of intestinal inflammation are described and illustrated by exemplary images. CONCLUSION The current manuscript provides standardized parameters and gives practical recommendations on how to report and how to characterize MRE findings in patients with IBD. KEY POINTS · Systematic overview provides practice-oriented recommendations and names and evaluates the decisive criteria for reporting and interpretation of MRI in inflammatory bowel disease.. · Standardized terminology and reporting criteria for MRI in IBD improves interdisciplinary communication.. · Standardized collection and documentation of MRI findings in IBD helps to further establish the method and to improve care for IBD patients..

Abstract
OBJECTIVE Aim: The aim of the study was to investigate the incidence of IBD in gastrointestinal surgery patients and record the disease's characteristics and treatment. PATIENTS AND METHODS Materials and Methods: A search was carried out in the archives of the gastroenterology clinics of the University General Hospital of Ioannina and the General Hospital of Ioannina "G. Hatzikosta" in Greece. All cases of operated patients from 1980 to 2018 were examined. The duration of the study was 4 months. Data were analyzed with the SPSS program, v.28. RESULTS Results: The total sample consisted of 1464 patients (n=1464). Most of them (915-62.5%) came from the University General Hospital of Ioannina, while the rest (549-37.5%) came from the GHI hospital "G. Hatzikosta". The mean age of the patients was 47 years (M=47.26, SD=17.34, Min=<1 month, Max=95 years). From the total sample, 58 patients (4%) suffered from IBD; most were men (42-72.41%). Their mean age was approximately 50 years (M=49.63, SD=16.48, Min=25 years, Max=77 years, range=52 years) and most belonged to the age groups of 31-40 years (11 patients- 19.6%) and 21-30 years and 61-70 years (10 patients-17.9%). The perianal disease was present in 43.1% (25 patients). The most frequent type of operation was fistula resection, ligation, curettage-biopsy (24.1%) and opening-drainage (22.4%-13 patients) and the most frequent type of anesthesia was general anesthesia (93.1%-54 patients). CONCLUSION Conclusions: This long-term study of the patients' data followed up over time showed that the possibility of surgery in patients with IBD is mitigated through systematic monitoring and multifaceted therapeutic treatment.The perianal disease which appeared more often in men shows that it can be diagnosed early and at an early stage and with the new minimally invasive techniques the patient with IBD can be treated with a better quality of life.

Lack of anti-TNF drugs levels in fistula tissue - a reason for nonresponse in Crohn's perianal fistulating disease? Eur J Gastroenterol Hepatol 2022; 34:18-26.

Abstract
INTRODUCTION Anti-TNF therapy is recommended as treatment for patients with Crohn´s perianal fistulas. However, a significant proportion of patients have a sub-optimal response to anti-TNF therapy. Higher serum levels of anti-TNF agents have been associated with improved outcomes in perianal Crohn's disease. Currently, it is unknown whether anti-TNF agent levels can be detected in tissue from fistula tracts themselves and whether this is associated with response. AIMS AND METHODS We undertook a pilot study to measure fistula tissue levels of anti-TNF medication (infliximab and adalimumab). We used a previously validated targeted proteomic technique, employing ultraperformance liquid chromatography-mass spectrometry, to detect/quantify anti-TNF drugs. Biopsies were obtained from fistula tracts of patients with Crohn's disease on maintenance treatment; with idiopathic (cryptoglandular) fistula tissues used as negative controls as well as positive controls (by spiking the latter tissues with anti-TNF drugs). RESULTS Tissue was sampled from the fistula tracts of seven patients with Crohn's perianal disease (five patients were on adalimumab and two patients were on infliximab). The anti-TNF drugs, infliximab and adalimumab, were not detected in fistula samples from any of the Crohn's patients despite detection in 'spiked' positive control samples. CONCLUSION Absence of detection of the anti-TNF drugs in fistula tissue raises the question on the role of tissue penetrance of anti-TNF drugs in response to therapy. Further work is required in a larger number of patients to validate the findings observed and investigate if any correlation exists between tissue and serum levels of anti-TNF and clinical outcome. SUMMARY Predicting response in Crohn's fistula patients on biologic therapy is difficult with no reliable biomarkers. This pilot study uses targeted proteomics to investigate the potential role of tissue drug levels in acting as a biomarker of treatment response.

Abstract
INTRODUCTION Few studies have investigated perianal fistula etiopathogenesis, and although the cryptoglandular theory is widely accepted in idiopathic cases, in Crohn's disease, it is thought to involve the interplay between microbiological, immunological and genetic factors. A pilot study was conducted to assess for metabolic variations in Crohn's perianal fistula tissue that might differ from that of idiopathic (cryptoglandular) perianal fistula tissue as a comparator. The goal was to identify any potential biomarkers of disease, which may improve the understanding of pathogenesis. AIMS AND METHODS Fistula tract biopsies were obtained from 30 patients with idiopathic perianal fistula and 20 patients with Crohn's anal fistula. Two different assays were used in an ultra-high-performance liquid chromatography system coupled with a mass spectrometric detector to achieve broad metabolome coverage. Univariate and multivariate statistical data analyses were used to identify differentiating metabolic features corresponding to the perianal fistula phenotype (i.e. Crohn's disease vs. idiopathic). RESULTS Significant orthogonal partial least squares discriminant analysis predictive models (validated with cross-validated-analysis of variance P value <0.05) differentiated metabolites from tissue samples from Crohn's vs. idiopathic anal fistula patients using both metabolic profiling platforms. A total of 41 metabolites were identified, suggesting alterations in pathways, including amino acid, carnitine and lipid metabolism. CONCLUSION Metabonomics may reveal biomarkers of Crohn's perianal fistula. Further work in larger numbers is required to validate the findings of these studies as well as cross-correlation with microbiome work to better understand the impact of host-gut/environment interactions in the pathophysiology of Crohn's and idiopathic perianal fistulas and identify novel therapeutic targets.

Abstract
Crohn’s Disease (CD) is a chronic inflammatory disorder in which up to 50% of patients develop fistula within 20 years after the initial diagnosis, and half of these patients suffer perianal fistulizing disease. The etiopathogenesis of CD-related perianal fistula is still unclear, and its phenotypical and molecular characteristics are even more indefinite. A better understanding would be crucial to develop targeted and more effective therapeutic strategies. At present, the most accredited theory for the formation of CD-related fistula identifies the epithelial-to-mesenchymal transition (EMT) as the driving force. It has been well recognized that CD carries an increased risk of malignancy, particularly mucinous adenocarcinoma is often associated with long-standing fistula in CD patients. Despite the availability of multiple treatment options, perianal fistulizing CD represents a therapeutic challenge and is associated with an important impact on patients’ quality of life. To date, the most effective management is multidisciplinary with the cooperation of gastroenterologists, surgeons, radiologists, and nutritionists and the best recommended treatment is a combination of medical and surgical approaches.

Abstract
A full understanding of the presentation and work-up of inflammatory bowel disease is necessary to ensure appropriate treatment of this complex disease. Crohn's disease and ulcerative colitis share many common clinical features but are treated very differently. This article covers the factors which contribute to IBD pathogenesis and presentation as well as the methods of diagnosis and work-up to ensure that the appropriate diagnosis is reached. This article also serves as a basis of understanding for the more complex aspects of the disease to be discussed in subsequent articles.

Abstract
BACKGROUND The characteristics of patients who develop a fistula-in-ano after an anorectal abscess are unclear. OBJECTIVE Our study explored this relationship and patient factors associated with fistula development. DESIGN International Classification of Diseases, 10 Revision, and Classification of Interventions and Procedures, version 4, codes were used to identify all of the patients with a primary anorectal abscess. Multivariable analysis was used to identify factors predictive of fistula formation. SETTINGS The study was conducted in a district general hospital. PATIENTS Patients with anorectal abscess who were admitted to our institution (2004-2015) were included. MAIN OUTCOMES MEASURES The rate of subsequent fistula formation was measured. RESULTS A total of 1970 abscess patients were identified; 70.0% (n = 1379) were men, and 7.3% (n = 144) had Crohn's disease. Fistulas occurred in 16.2% (n = 319) at a median of 7 months (interquartile range, 3-7 mo). Patients with Crohn's disease were more than twice as likely to develop a fistula than patients without Crohn's disease (32.6% vs 14.9%; OR = 2.5 (95% CI, 1.7-3.7); p < 0.001). Patients with Crohn's disease with a fistula were more likely to be women (55.3% vs 34.6%; p = 0.007) and aged <30 years (51.1% vs 24.3%; p< 0.001) versus patients without Crohn's disease with a fistula. At multivariable analysis of the entire cohort, male sex (OR = 0.7 (95% CI, 0.5-0.9); p = 0.005) and diabetes mellitus (OR = 0.5 (95% CI, 0.3-0.9); p = 0.027) were associated with a reduced likelihood of developing a fistula after abscess formation. LIMITATIONS The study was limited by its single-center scope, retrospective analysis, and lack of a standardized definition for Crohn's disease. CONCLUSIONS Abscesses are more common in men, but progression to fistula is more likely in women. The rate of fistula progression in Crohn's disease is twice that in patients without Crohn's disease. Identification of patients at risk may help delineate those who will benefit from a more conservative surgical approach, enhanced follow-up, or investigation after abscess drainage.

Abstract
BACKGROUND Evidence from groups who have studied fistula aetiology and extrapolation from interventional studies supports a multifactorial hypothesis of Crohn's perianal fistula, with several pathophysiological elements that may contribute to fistula formation, persistence and resistance to treatment. AIM An evidence synthesis of current understanding of pathophysiological factors underlying Crohn's perianal fistula is presented, exploring the fundamental reasons why some treatments succeed and others fail, as a means of focussing clinical knowledge on improving treatment of Crohn's perianal fistula. METHODS Evidence to support this review was gathered via the Pubmed database. Studies discussing pathophysiological factors underpinning perianal fistula, particularly in Crohn's disease, were reviewed and cross-referenced for additional reports. RESULTS Pathophysiological factors that impact on success or failure of interventions for Crohn's perianal fistulae include the high-pressure zone, obliterating the dead space, disconnecting the track from the anus, removing epithelialisation, eradicating sepsis and by-products of bacterial colonisation, correcting abnormalities in wound repair and removing the pro-inflammatory environment which allows fistula persistence. Most current interventions for Crohn's perianal fistulae tend to focus on a single, or at best two, aspects of the pathophysiology of Crohn's anal fistulae; as a result, failure to heal fully is common. CONCLUSIONS For an intervention or combination of interventions to succeed, multiple factors must be addressed. We hypothesise that correct, timely and complete attention to all of these factors in a multimodal approach represents a new direction that may enable the creation of an effective treatment algorithm for Crohn's anal fistula.

Abstract
Purpose While perianal disease (PAD) is a characteristic of patients with Crohn disease, it has been overlooked in patients with ulcerative colitis (UC). Thus, our study aimed to analyze the incidence and the clinical features of PAD in patients with UC. Methods We reviewed the data on 944 patients with an initial diagnosis of UC from October 2003 to October 2015. PAD was categorized as hemorrhoids, anal fissures, abscesses, and fistulae after anoscopic examination by experienced proctologists. Data on patients’ demographics, incidence and types of PAD, medications, surgical therapies, and clinical course were analyzed. Results The median follow-up period was 58 months (range, 12–142 months). Of the 944 UC patients, the cumulative incidence rates of PAD were 8.1% and 16.0% at 5 and 10 years, respectively. The incidence rates of bleeding hemorrhoids, anal fissures, abscesses, and fistulae at 10 years were 6.7%, 5.3%, 2.6%, and 3.4%, respectively. The cumulative incidence rates of perianal sepsis (abscess or fistula) were 2.2% and 4.5% at 5 and 10 years, respectively. In the multivariate analyses, male sex (risk ratio [RR], 4.6; 95% confidence interval [CI], 1.7–12.5) and extensive disease (RR, 4.2; 95% CI, 1.6–10.9) were significantly associated with the development of perianal sepsis. Conclusion Although the clinical course of PAD in patients with UC is not serious, in clinical practice, PAD is not rare in such patients. Therefore, careful examination and appropriate management for PAD is needed if the quality of life for patients with UC is to be improved.

Abstract
Computed tomography and magnetic resonance enterography have become routine small bowel imaging tests to evaluate patients with established or suspected Crohn's disease, but the interpretation and use of these imaging modalities can vary widely. A shared understanding of imaging findings, nomenclature, and utilization will improve the utility of these imaging techniques to guide treatment options, as well as assess for treatment response and complications. Representatives from the Society of Abdominal Radiology Crohn's Disease-Focused Panel, the Society of Pediatric Radiology, the American Gastroenterological Association, and other experts, systematically evaluated evidence for imaging findings associated with small bowel Crohn's disease enteric inflammation and established recommendations for the evaluation, interpretation, and use of computed tomography and magnetic resonance enterography in small bowel Crohn's disease. This work makes recommendations for imaging findings that indicate small bowel Crohn's disease, how inflammatory small bowel Crohn's disease and its complications should be described, elucidates potential extra-enteric findings that may be seen at imaging, and recommends that cross-sectional enterography should be performed at diagnosis of Crohn's disease and considered for small bowel Crohn's disease monitoring paradigms. A useful morphologic construct describing how imaging findings evolve with disease progression and response is described, and standard impressions for radiologic reports that convey meaningful information to gastroenterologists and surgeons are presented.

Abstract
Perianal fistulas are a major problem in many patients with Crohn's disease. These are usually complex fistulas that adversely affect patients' quality of life, and their clinical management is difficult. Medical treatment sometimes achieves cessation of discharge and closure of the external opening; however, it is difficult to assess the status of the rest of the fistula tract. Magnetic resonance imaging is the method of choice with which to evaluate the condition of perianal fistulas and allows for assessment of the status of inaccessible areas. Magnetic resonance imaging also allows the clinician to evaluate other perianal manifestations of Crohn's disease that differ from the fistulas. This imaging technique is therefore a fundamental means of patient monitoring. When used in conjunction with assessment of the patient's morphological findings, it provides information that allows for both quantification of disease severity and evaluation of the response to treatment. New types of magnetic resonance sequences are emerging, such as diffusion, perfusion, and magnetisation transfer. These sequences may serve as biomarkers because they provide information reflecting the changes taking place at the molecular level. This will help to shape a new scenario in the early assessment of the response to treatments such as anti-tumour necrosis factor drugs. TEACHING POINTS • MRI is the method of choice with which to evaluate perianal fistulas. • In perianal Crohn's disease, MRI is a fundamental means of patient monitoring. • The usefulness of the Van Assche score for patient monitoring remains unclear. • New MRI sequences' diffusion, perfusion, and magnetisation transfer may serve as biomarkers.

Abstract
BACKGROUND Data on the outcomes of children with perianal Crohn's disease are limited. We aimed to assess phenotypic features at diagnosis and long-term disease-specific outcomes of this phenotype. METHODS The medical records of 296 pediatric onset patients with Crohn's disease, diagnosed from 2001 to 2015, were reviewed retrospectively. Baseline characteristics included age, sex, severity indices, laboratory data, endoscopic findings, and anthropometric measurements. Main outcome measures included time to first flare, hospitalization, surgery, and biological therapy. RESULTS Of the 296 included patients (median age 14.2 years), 70 (24%) had nonfistulizing perianal findings, whereas only 40 (13%) had fistulizing perianal disease at diagnosis. Perianal involvement was associated with female sex (P = 0.01), whereas fistulizing perianal disease resulted in a greater use of immunomodulators (P = 0.01). Time to hospitalization was shorter for both nonfistulizing and fistulizing perianal disease (hazard ratio [HR] 1.66 and 1.34, respectively, P = 0.027) and time to biological therapy (HR 2.1 and 1.7, respectively, P = 0.002). There were no differences in time to first flare or surgery. During a median follow-up of 8.5 years, additional 26 patients (10%) developed fistulizing perianal disease after a median time of 3.5 years. The presence of nonfistulizing disease at diagnosis was a significant risk factor for the development of fistulizing perianal disease (HR 3.4, P = 0.002). At the end of follow-up, complicated disease was more common in patients with any perianal involvement (P = 0.01). CONCLUSIONS Pediatric patients with Crohn's disease with both nonfistulizing and fistulizing disease have worse clinical outcomes. Nonfistulizing disease is a risk factor for the development of fistulizing disease over time.

Abstract
OBJECTIVES Data on the outcomes of children with perianal Crohn disease (pCD) are limited, although its presence is often used for justifying early use of biologics. We aimed to assess whether pCD in children is associated with more severe outcomes as found in adults. METHODS Data were extracted from the ImageKids database, a prospective, multicenter, longitudinal cohort study. The study enrolled 246 children at disease onset or thereafter. All patients underwent comprehensive clinical, endoscopic, and radiologic evaluation at enrollment; 98 children had repeat evaluation at 18 months. RESULTS Of the 234 included patients (mean age 14.2 ± 2.4 years; 131 [56%] boys), 57 (24%) had perianal findings, whereas only 21 (9%) had fistulizing perianal disease. Children with pCD had reduced weight and height z scores compared with non-pCD patients (-0.9 vs -0.35, P = 0.03 and -0.68 vs -0.23, respectively; P = 0.04), higher weighted pediatric CD activity index (32 [interquartile range 16-50] vs 20 [8-37]; P = 0.004), lower serum albumin (3.6 ± 0.7 vs 4.5 ± 0.8, P = 0.016), and higher magnetic resonance enterography global inflammatory score (P = 0.04). Children with pCD had more rectal (57% vs 38%, P = 0.04), and jejunal involvement (31% vs 11% P = 0.003) and a higher prevalence of granulomas (64% vs 23%, P = 0.0001). Magnetic resonance enterography-based damage scores did not differ between groups. Patients with skin tags/fissures only, had similar clinical, endoscopic, and radiologic characteristics as patients with no perianal findings. CONCLUSIONS Pediatric patients with pCD with fistulizing disease have distinct phenotypic features and a predisposition to a greater inflammatory burden.

Abstract
Background Psychological assessment is not commonly performed nor easily accepted by coloproctological patients. Our aim was to evaluate the psychological component of coloproctological disorders using uncommon tools. Methods The 21-Item Depression Anxiety and Stress Scale and the Pescatori projective test were applied to coloproctological outpatients of the Gastroenterology Department of our hospital as well as to healthy volunteers. Results Seventy patients (median age 47 years, 22 male) divided in 4 groups (functional constipation, constipated irritable bowel syndrome, benign anorectal disease and perianal Crohn’s disease) and 52 healthy volunteers (age 45 years, 18 male) completed the tests. Proctological patients showed higher scores of depression (P<0.001), anxiety (P<0.001), and stress (P<0.001) compared to healthy participants. Compared to the control group, patients with functional constipation, irritable bowel syndrome and perianal Crohn’s disease maintained the highest scores in all subscales (P<0.05), while patients with benign anorectal disease only had higher anxiety and stress (P<0.001) scores. The patients’ also showed lower scores in the Pescatori projective test (P=0.012). A weak association between the projective test and the depression subscale was found (P=0.05). Conclusion Proctological patients had higher scores of depression, anxiety and stress and lower scores in the Pescatori projective test compared to healthy controls.

Abstract
Perianal Crohn’s disease affects a significant number of patients with Crohn’s disease and is associated with poor quality of life. The nature of the disease, compounded by presentation of various disease severities, has made the treatment of perianal Crohn’s disease difficult. The field continues to evolve with the use of both historical and contemporary solutions to address the challenges associated with it. The goal of this article is to review current literature regarding medical and surgical treatment, as well as the future directions of therapy.

Abstract
PURPOSE Infliximab is currently used for the treatment of active Crohn's disease (CD). We aimed to assess the efficacy and safety of infliximab therapy and to determine the predictors of response in Korean patients with CD. MATERIALS AND METHODS A total of 317 patients who received at least one infliximab infusion for active luminal CD (n=198) and fistulizing CD (n=86) or both (n=33) were reviewed retrospectively in 29 Korean referral centers. Clinical outcomes of induction and maintenance therapy with infliximab, predictors of response, and adverse events were evaluated. RESULTS In patients with luminal CD, the rates of clinical response and remission at week 14 were 89.2% and 60.0%, respectively. Male gender and isolated colonic disease were associated with higher remission rates at week 14. In week-14 responders, the probabilities of sustained response and remission were 96.2% and 93.3% at week 30 and 88.0% and 77.0% at week 54, respectively. In patients with fistulizing CD, clinical response and remission were observed in 85.0% and 56.2% of patients, respectively, at week 14. In week-14 responders, the probabilities of sustained response and remission were 94.0% and 97.1%, respectively, at both week 30 and week 54. Thirty-nine patients (12.3%) experienced adverse events related to infliximab. Serious adverse events developed in 19 (6.0%) patients including seven cases of active pulmonary tuberculosis. CONCLUSION Infliximab induction and maintenance therapy are effective and well tolerable in Korean patients with luminal and fistulizing CD. However, clinicians must be aware of the risk of rare yet critical adverse events.

Abstract
BACKGROUND AND AIMS In Western countries, tuberculous anal fistula may not be an issue because tuberculosis [TB] is not common, and this is a very rare form of extrapulmonary manifestation of TB. However in TB-endemic countries, careful diagnostic differentiation is required because the clinical features of TB anal fistula and Crohn's disease [CD] anal fistula are similar, with distinguishing features remaining unclear. We aimed to analyse the clinical features of TB versus CD anal fistulas. METHOD Among 13872 patients who underwent anal fistula surgery from 2003 to 2014, 87 patients with TB fistulas and 116 patients with CD fistulas were included. Data on the annual incidence of TB and CD, as well as the clinical, pathological, ultrasonographic, colonoscopic and surgical data were analysed. RESULTS Compared with CD, the TB group was older [median: 37 vs 22 years] and underlying chronic illness was more common [20.3% vs 2.6%]. In the TB group, 46 patients [59.7%] showed active or inactive pulmonary TB, and acid-fast bacilli and caseating granuloma were found in 56.3% and 62.1%, respectively. During colonoscopy, mucosal lesions were observed more frequently in CD [96.9% vs 16.9%]. CONCLUSIONS TB anal fistula is clinically very similar to CD anal fistula. In Korea, the incidence of CD anal fistula has recently increased in prevalence, whereas the prevalence of TB anal fistula is decreasing but is still persistent. We recommend that clinicians should prepare for a possibility of TB as well as CD anal fistula in TB-endemic countries including Korea.

Abstract
Perianal fistulas in Crohn's disease are common and difficult to treat. Their aetiology is poorly understood. Assessment is clinical, endoscopic and radiological, and management is undertaken by a multidisciplinary team of gastroenterologists, surgeons and radiologists. Surgical drainage of the fistula tract system with the placement of loose setons precedes combined therapy with immunosuppressant and anti-TNFα agents in most patients. Proctitis should be rigorously eliminated where possible. Definitive surgical repair is sometimes possible and diversion or proctectomy are occasionally required. Combined medical and surgical management represents a promising avenue for the future.

Abstract
AIM Psychological stress is known to affect the immunologic system and the inflammatory response. The aim of this study was to assess the presence of psychological stress, anxiety, and depression in patients with anal fistula. METHODS Consecutive patients with anal fistula, hemorrhoids, and normal volunteers were studied prospectively. Stressful life events were recorded and subjects were asked to complete the state-trait anxiety inventory (STAI), a depression scale, and three different reactive graphic tests (RGT). RESULTS Seventy-eight fistula patients, 73 patients with grade III-IV hemorrhoids, and 37 normal volunteers were enrolled. Of the fistula patients, 65 (83 %) reported one or more stressful events in the year prior to diagnosis, compared to 16 (22 %) of the hemorrhoid patients (P = 0.001). There were no significant differences in the percentage of subjects with abnormal trait anxiety (i.e., proneness for anxiety) and depression scores between fistula patients, hemorrhoid patients, and controls. Fistula patients had significantly higher (i.e., better) scores compared to hemorrhoid patients in two of three RGT and significantly lower (i.e., worse) scores in all three RGT compared to healthy volunteers. Of 37 patients followed up for a median of 28 months (range 19-41 months) after surgery, 8 (21.6 %) had persistent or recurrent sepsis. There was no significant difference in depression, STAI, and RGT scores between patients with sepsis and patients whose fistula healed. CONCLUSION Our results suggest that an altered emotional state plays an important role in the pathogenesis of anal fistula and underline the importance of psychological screening in patients with anorectal disorders.

Abstract
AIM The aetiology of Crohn's disease-related anal fistula remains obscure. Microbiological, genetic and immunological factors are thought to play a role but are not well understood. The microbiota within anal fistula tracts has never been examined using molecular techniques. The present study aimed to characterize the microbiota in the tracts of patients with Crohn's and idiopathic anal fistula. METHOD Samples from the fistula tract and rectum of patients with Crohn's and idiopathic anal fistula were analysed using fluorescent in situ hybridization, Gram staining and scanning electron microscopy were performed to identify and quantify the bacteria present. RESULTS Fifty-one patients, including 20 with Crohn's anal fistula, 18 with idiopathic anal fistula and 13 with luminal Crohn's disease and no anal fistula, were recruited. Bacteria were not found in close association with the luminal surface of any of the anal fistula tracts. CONCLUSION Anal fistula tracts generally do not harbour high levels of mucosa-associated microbiota. Crohn's anal fistulas do not seem to harbour specific bacteria. Alternative explanations for the persistence of anal fistula are needed.

Surgical treatment of perianal fistulizing Crohn's disease: from lay-open to cell-based therapy--an overview. ScientificWorldJournal 2014; 2014:146281.

Abstract
Background. Perianal Crohn's disease (CD) can be challenging. Despite the high incidence of fistulizing CD, literature lacks clear guidelines. Several medical, surgical, and combined treatment modalities have been proposed, but evidences are scarce. Methods. We searched the literature to assess the facets of perianal CD, with particular focus on complex fistulae. Disease epidemiology, classification, diagnosis, activity scoring systems, and medical-surgical treatments were assessed. Results. Perianal fistulizing CD is common, frequently associated with upper gastrointestinal and colorectal CD. Complex fistulas often require repeated treatments. Continence is a major concern when dealing with repeated procedures. A prudent pathway is to resolve active sepsis and to limit damages, delaying a definitive treatment to the time when acute phase has been controlled. The improved diagnostic techniques allow better preoperative planning and are useful in monitoring the response to treatment. Besides newer devices, cell-based treatments are promising tools which have recently enriched the treatment portfolio. However, the need for proctectomy is still disturbingly high in CD patients with complex perianal fistulae. Conclusions. Perianal CD can impair quality of life and lead to need for proctectomy. A staged approach is reasonable. Treatment success can be improved by multimodal treatment and collaborative management by experienced gastroenterologists and surgeons.

Abstract
BACKGROUND AND AIM The expression of interleukin (IL)-17 is upregulated in inflammatory bowel disease (IBD). Since fibroblasts are known to be responsive to IL-17, they may play a role in the modulation of inflammatory responses in IBD. Here, the effects of IL-17 on ileum and colon fibroblasts from Crohn's disease (CD) and ulcerative colitis (UC) patients are investigated, as compared to controls. METHODS Fibroblasts were isolated from surgical specimens taken from the tissue of 21 CD patients, 5 UC patients, and 14 patients undergoing surgery for colorectal carcinoma (control). The fibroblasts were cultured with and without IL-17. We performed mRNA microarray analysis on cultured fibroblasts, isolated from three CD samples and three control samples. Based on these results, the expression of IL-17 induced genes was validated in a larger selection of samples using qRT-PCR and ELISA. RESULTS The mRNA microarray showed that IL-17 induced the expression levels of various genes in fibroblasts of CD patients and controls, among which NFKBIZ, CXCL1, and CXCL6 demonstrated the most prominent response. qRT-PCR validated that IL-17 induced the expression of NFKBIZ significantly (p=0.028) in intestinal fibroblasts of CD patients. By performing an ELISA, we also discovered that, following IL-17 stimulation, CXCL1 levels were significantly increased in fibroblasts from CD patients (p=0.048). IL-17 also stimulated secretion of CXCL6 in fibroblasts from UC patients (p=0.053). CONCLUSION The enhanced expression of IL-17 that is observed in patients with Crohn's disease could act on intestinal fibroblasts to induce expression of transcription factor NFKBIZ and proinflammatory chemokine CXCL1. This can have consequences for fibroblast activity and neutrophil chemotaxis.

Abstract
Fistulas are a frequent manifestation of Crohn's disease (CD) and can result in considerable morbidity. Approximately 35% of all patients with CD will experience one fistula episode during their disease course of which 54% is perianal. The major symptoms of patients with perianal fistulas are constant anal pain, the formation of painful swellings around the anus and continuous discharge of pus and/or blood from the external fistula opening. The exact aetiology of perianal fistulas in CD patients remains unclear, but it is thought that a penetrating ulcer in the rectal mucosa caused by active CD forms an abnormal passage between the epithelial lining of the rectum and the perianal skin. Genetic, microbiological and immunological factors seem to play important roles in this process. Although the incidence of perianal fistulas in patients with CD is quite high, an effective treatment is not yet discovered. In this review all available medical and surgical therapies are discussed and new treatment options and research targets will be highlighted.

Abstract
BACKGROUND AST-120 (spherical carbon adsorbent) was previously reported to be effective for perianal fistula healing in Japanese patients with mild-to-moderate Crohn's disease. METHODS To evaluate the efficacy and safety of AST-120 in a Western population, a phase 3, multicenter, randomized, double-blind, placebo-controlled, study (FHAST-1) was conducted in adult patients with at least 1 draining perianal fistula and a Crohn's disease activity index <400. Patients received either AST-120 or matching placebo at a dose of 2 g 3 times daily for 8 weeks. The primary endpoint was the proportion of patients with treatment success, defined as a 50% reduction in the number of draining fistulae, at both weeks 4 and 8. A multivariate model was generated to assess covariates for treatment success among baseline variables. RESULTS Two hundred forty-nine patients were randomized (AST-120; n = 122; placebo, n = 127). The proportions of patients achieving the primary endpoint were no different between treatment groups (13.9% versus 16.5%, P = 0.6). No differences in fistula response were noted at week 4 (23.0% versus 25.2%, P = 0.77) or week 8 (27.0 versus 34.6%, P = 0.22). Serum C-reactive protein concentrations >0.6 mg/dL and Crohn's disease activity index scores >151 at baseline were associated with a reduced likelihood of treatment success (odds ratio, 0.40; confidence interval, 0.19-0.87; P = 0.02; and odds ratio, 0.45; confidence interval, 0.21-0.97; P = 0.04, respectively). CONCLUSIONS In this largest placebo-controlled trial to date to evaluate the impact of a therapeutic agent on perianal fistulae in Crohn's disease, the efficacy of AST-120 could not be confirmed. An inverse relationship was observed between both inflammatory and clinical disease activity and fistula response.

Abstract
The gastrointestinal microbiota is a complex ecosystem with each human individual hosting at least 160 different bacterial strains. Our understanding of its role is rapidly expanding as a result of the molecular microbiological techniques that can accurately characterise its composition and 'omics' technologies that measure its metabolic activity. Since 1995, extensive research has investigated the prebiotic concept, which describes how supplementation of some non-digestible oligosaccharides can stimulate the growth and/or activity of specific genera including bifidobacteria. However, the vast majority of studies are in healthy human subjects, with few undertaken in patients with disorders relevant to clinical nutrition. Marked alterations of the luminal microbiota have been demonstrated in patients with digestive disorders, highlighting mechanisms through which they might be involved in their pathogenesis, including higher clostridia in patients who develop diarrhoea during enteral nutrition and the influence of bifidobacteria on intestinal dendritic cell phenotype in Crohn's disease. The impact of prebiotics on the intestinal microbiota of healthy people has not been consistently replicated in patients with digestive disorders. For example, a number of studies show that inulin/oligofructose do not increase bifidobacteria in enteral nutrition and Crohn's disease. Indeed, in Crohn's disease and irritable bowel syndrome there is evidence that some prebiotics in high doses worsen functional symptoms. Unlike healthy human subjects, patients experience a number of issues that may alter their gastrointestinal microbiota (disease, antibiotics and inflammation) and the use of microbiota modifying therapies, such as prebiotics, do not always elicit the same effects in patients as they do in healthy people.

Abstract
BACKGROUND Crohn's disease (CD) is characterised by periods of relapse and remission. Over time the disease leads almost inevitably to the complications of stricturing, penetration and fistulisation. Perianal CD involves areas of chronic abscess formation, ulceration, skin tags or fistula formation. This can be a particularly challenging and complex problem to manage, and a range of potential treatment modalities exist. METHODS This review covers the management of perianal CD and provides recommendations for practice for the multidisciplinary team (MDT), including the use of wound management products and relevant clinical images. RESULTS Current practice focuses predominantly on the use of antibiotic therapy, immunosuppression, immunomodulation and surgery. These therapies are used individually or in combination. The majority of evidence suggests that a combination of medical and surgical management produces the best disease outcomes. However, this treatment regime can be debilitating for the patient and compliance can be difficult. Published work on the use of topical therapy in the management of perianal CD focuses specifically on topical drug therapy; it does not, however, address the basic guiding principles of chronic wound management-in particular, optimal moisture control and the management of bacterial burden on the wound surface. Honey and silver-containing wound management products act as topical antimicrobial agents and therefore address these principles. CONCLUSIONS Perianal CD is the archetypal condition that exemplifies the need for an MDT approach in caring for patients with inflammatory bowel disease. A combination of treatment modalities that includes topical wound management is likely to produce the best patient outcomes.

Abstract
BACKGROUND Imaging modalities such as endoanal ultrasound or MRI can be useful preoperative adjuncts before the appropriate surgical intervention for perianal fistulas. OBJECTIVES We present a systematic review of published literature comparing endoanal ultrasound with MRI for the assessment of idiopathic and Crohn's perianal fistulas. DESIGN A meta-analysis was performed to obtain pooled values for specificity and sensitivity. SETTINGS Electronic databases were searched from January 1970 to October 2010 for published studies. PATIENTS AND INTERVENTIONS Four studies were used in our analysis. There were 241 fistulas in the ultrasound group and 240 in the magnetic resonance group. RESULTS The combined sensitivity and specificity of magnetic resonance for fistula detection were 0.87 (95% CI: 0.63-0.96) and 0.69 (95% CI: 0.51-0.82). There was a high degree of heterogeneity between studies reporting on MRI sensitivity (df = 3, I = 93%). This compares to a sensitivity and specificity for endoanal ultrasound of 0.87 (95% CI: 0.70-0.95) and 0.43 (95% CI: 0.21-0.69). There was a high degree of heterogeneity between studies reporting on endoanal ultrasound sensitivity (df = 3, I = 92%). CONCLUSIONS From the available literature, the summarized performance characteristics for MRI and endoanal ultrasound demonstrate comparable sensitivities at detecting perianal fistulas, although the specificity for MRI was higher than that for endoanal ultrasound. Both specificity values are considered to be diagnostically poor, however. The high degree of data heterogeneity and the shortage of applicable studies precludes any firm conclusions being made for clinical practice. Future trials with improved study design (including prospective data collection and consideration of verification bias) may help to further clarify the role of MRI in the assessment and treatment response monitoring of perianal fistulas (particularly in patients with Crohn's disease).

Abstract
Perianal lesions are common in patients with Crohn’s disease, and display aggressive behavior in some cases. An accurate diagnosis is necessary for the optimal management of perianal lesions. Treatment of perianal Crohn’s disease includes medical and/or surgical options. Recent discoveries in the pathogenesis of this disease have led to advances in medical and surgical therapy with good results. Perianal lesions in Crohn’s disease remain a challenging aspect for both gastroenterologists and surgeons and lead to a greatly impaired quality of life for all patients affected by this disease. A multidisciplinary approach is mandatory to obtain the best results.

Abstract
BACKGROUND & AIMS Magnetic resonance imaging (MRI) is used to assess the outcome of infliximab (IFX) therapy in patients with perianal fistulizing Crohn's disease (pfCD). However, few long-term data are available about its efficacy. METHODS We assessed 59 patients with pfCD by MRI and clinical evaluation at baseline. Treated patients then received paired clinical and MRI examinations for a median time period of 36 (11-53.3) weeks. Short-, mid-, and long-term effects of therapy, as well as the ability of MRI to predict treatment outcome and need for surgery, were evaluated. RESULTS Compared with the baseline MRI, the short-term follow-up MRI (n = 29) revealed a reduced number of fistula tracks in 13.8% and in the inflammatory activity in 55.2% of patients, respectively; mid-term MRI (n = 25) in 56% and in 52%, respectively; and long-term MRI (n = 13) in 15.4% and in 31%, respectively. Improvement of pfCD based on MRI results coincided with clinical improvement in 54.7% of the patients. Short-term and mid-term (but not long-term) MRI showed a significant decrease in the activity score. Therapy outcome was worse among patients with persisting fistulas (P = .01), collections (P = .009), and rectal wall involvement (P = .01) in the final MRI. Patients with single-branched fistulas (P < .0001) and collections (P = .006) in their baseline MRI were more likely to undergo surgery. CONCLUSIONS MRI is a useful technique for evaluation of pfCD during the first year of follow-up. In the long-term, the MRI improvement coincides with clinical and endoscopic response to IFX in 50% of the patients.
