Abstract
Background Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the most established restorative operative approach for patients with ulcerative colitis. It has associated morbidity and the potential for major repercussions on quality of life. As such, patient selection is crucial to its success. The main aim of this paper is to present an institutional preoperative checklist to support clinical risk assessment and patient selection in those considering IPAA. Methods A literature review was performed to identify the risk factors associated with surgical complications, decreased functional outcomes/quality of life, and pouch failure after IPAA. Based on this, a preliminary checklist was devised and modified through an iterative process. This was then evaluated by a consensus group comprising the pouch multidisciplinary team (MDT) core members. Results The final preoperative checklist includes assessment for risk factors such as gender, advanced age, obesity, comorbidities, sphincteric impairment, Crohn's disease and pelvic radiation therapy. In addition, essential steps in the decision-making process, such as pouch nurse counselling and discussion regarding surgical alternatives, are also included. The last step of the checklist is discussion at a dedicated pouch-MDT. Discussion A preoperative checklist may support clinicians with the selection of patients that are suitable for pouch surgery. It also serves as a useful tool to inform the discussion of cases at the MDT meeting.

Abstract
AIM Patient understanding of disease can guide decision-making in the management of anal fistula. This prospective feasibility study aimed to assess the acceptability and methods of assessing the impact of viewing realistic models on patients with anal fistula. METHODS New referrals to a tertiary clinic participated in this single-centre, parallel-group randomized controlled study. Baseline characteristics, Decisional Conflict Scale and understanding of disease were assessed pre-consultation. Participants were randomized to a standard consultation, where disease and treatment options were explained using magnetic resonance images and drawn diagrams, or a similar consultation supplemented with an appropriate generic three-dimensional (3D) printed model. Understanding of disease and proposed surgery, Decisional Conflict Scale and ratings of visual aids were assessed post-consultation, along with 3D model feedback. RESULTS All 52 patients who were approached agreed to be randomized (25 standard, 27 3D consultation). Understanding of disease increased post-consultation in both groups. Post-consultation decisional conflict (0, no; 100, high decisional conflict) was low (median 27 post-standard vs. 24 post-3D consultation). Patients scored highly on measures assessing understanding of proposed surgery. 3D models were rated highly, with 96% of patients wanting to see them again in future consultations. CONCLUSIONS Three-dimensional printed fistula models are a welcome addition to outpatient consultations with results suggesting that understanding of surgery is improved. A future trial should be powered to detect whether 3D models result in a significant improvement in understanding beyond traditional methods of explanation and explore the conditions in which models have their maximal utility. CLINICALTRIALS GOV REGISTRATION ID This study was registered on ClinicalTrials.gov (ID: NCT04069728). Registered on 23 August 2019.

Abstract
AIM Quality of life (QoL) is a crucial and core outcome in assessing the effectiveness of treatments for cryptoglandular anal fistula. Despite its extensive impact, there is a lack of patient-centred, disease-specific QoL measurement instruments of adequate quality. The aim of this study is to develop a disease-specific measurement instrument that can accurately measure QoL for patients with cryptoglandular anal fistula. METHOD Semi-structured qualitative patient interviews and a systematic review of current instruments were used to generate items for the draft instrument. This underwent successive rounds of cognitive interviews to refine its wording and structure. Individual item and overall scale content validity were determined by asking experts to rate the relevance of each item and those deemed irrelevant were removed. The final instrument then underwent psychometric testing and test-retest analysis to determine its sensitivity and stability. RESULTS A total of 148 patients were involved in item generation, scale development and psychometric testing. A 22-item measurement instrument has been developed; it is scored on a scale of 0-100, where 0 indicates the worst QoL and 100 demonstrates perfect QoL. The scale demonstrates excellent internal consistency (Cronbach-α = 0.927), strong content and construct validity [correlation with Perianal Disease Activity Index = -0.713, Hospital Anxiety and Depression Anxiety (-0.659) and Depression (-0.673) subscales and Short Form-12 physical (0.609) and mental (0.589) component scales] and strong reliability and responsiveness. CONCLUSION We have developed a cryptoglandular Anal Fistula Quality of Life scale (AF-QoL), a comprehensive, disease-specific patient reported outcome measure assessing QoL in patients with cryptoglandular anal fistula.

Abstract
AIM The primary aim of the European Society of Coloproctology (ESCP) Guideline Development Group (GDG) was to produce high-quality, evidence-based guidelines for the management of cryptoglandular anal fistula with input from a multidisciplinary group and using transparent, reproducible methodology. METHODS Previously published methodology in guideline development by the ESCP has been replicated in this project. The guideline development process followed the requirements of the AGREE-S tool kit. Six phases can be identified in the methodology. Phase one sets the scope of the guideline, which addresses the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula in adult patients presenting to secondary care. The target population for this guideline are healthcare practitioners in secondary care and patients interested in understanding the clinical evidence available for various surgical interventions for anal fistula. Phase two involved formulation of the GDG. The GDG consisted of 21 coloproctologists, three research fellows, a radiologist and a methodologist. Stakeholders were chosen for their clinical and academic involvement in the management of anal fistula as well as being representative of the geographical variation among the ESCP membership. Five patients were recruited from patient groups to review the draft guideline. These patients attended two virtual meetings to discuss the evidence and suggest amendments. In phase three, patient/population, intervention, comparison and outcomes questions were formulated by the GDG. The GDG ratified 250 questions and chose 45 for inclusion in the guideline. In phase four, critical and important outcomes were confirmed for inclusion. Important outcomes were pain and wound healing. Critical outcomes were fistula healing, fistula recurrence and incontinence. These outcomes formed part of the inclusion criteria for the literature search. In phase five, a literature search was performed of MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews by eight teams of the GDG. Data were extracted and submitted for review by the GDG in a draft guideline. The most recent systematic reviews were prioritized for inclusion. Studies published since the most recent systematic review were included in our analysis by conducting a new meta-analysis using Review manager. In phase six, recommendations were formulated, using grading of recommendations, assessment, development, and evaluations, in three virtual meetings of the GDG. RESULTS In seven sections covering the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula, there are 42 recommendations. CONCLUSION This is an up-to-date international guideline on the management of cryptoglandular anal fistula using methodology prescribed by the AGREE enterprise.

Abstract
BACKGROUND Patients with Crohn's disease (CD) are at risk of developing complications such as perianal fistulas. Patients with Crohn's perianal fistulas (CPF) are affected by fecal incontinence (FI), bleeding, pain, swelling, and purulent perianal discharge, and generally face a higher treatment burden than patients with CD without CPF. AIM To gain insights into the burden of illness/quality of life in patients with CPF and their treatment preferences and satisfaction. METHODS This cross-sectional observational study was conducted in patients with CD aged 21-90 years via a web-enabled questionnaire in seven countries (April-August 2021). Patients were recruited into three cohorts: Cohort 1 included patients without perianal fistulas; cohort 2 included patients with perianal fistulas without fistula-related surgery; and cohort 3 included patients with perianal fistulas and fistula-related surgery. Validated patient-reported outcome measures were used to assess quality of life. Drivers of treatment preferences were measured using a discrete choice experiment (DCE). RESULTS In total, 929 patients were recruited (cohort 1, n = 620; cohort 2, n = 174; cohort 3, n = 135). Short Inflammatory Bowel Disease Questionnaire scores were worse for patients with CPF (cohorts 2 and 3) than for those with CD without CPF (cohort 1): Mean score 3.8 and 3.7 vs 4.1, respectively, (P < 0.001). Similarly, mean Revised FI and FI Quality of Life scores were worse for patients with CPF than for those with CD without CPF. Quality of Life with Anal Fistula scores were similar in patients with CPF with or without CPF-related surgery (cohorts 2 and 3): Mean score 41 and 42, respectively. In the DCE, postoperative discomfort and fistula healing rate were the most important treatment attributes influencing treatment choice: Mean relative importance 35.7 and 24.7, respectively. CONCLUSION The burden of illness in CD is significantly higher for patients with CPF and patients rate lower postoperative discomfort and higher healing rates as the most desirable treatment attributes.

Abstract
Perianal fistulizing Crohn's Disease (pCD) affects about 25% of patients with Crohn's Disease (CD). It remains a difficult entity to manage with a therapeutic ceiling of treatment success despite improving medical and surgical management. The refractory nature of the disease calls for an imminent need to better understand its immunopathogenesis and classification to better streamline our treatment options. In this article, we overview the current state of pCD management and discuss where the future of its management may lie.

Abstract
AIM Pilonidal disease is a benign condition that affects mainly the young. In existing literature, there is no consensus for best treatment, with multiple operative techniques described, some complex, resulting in a high proportion of failure and/or morbidity. The cleft closure (or cleft lift) described by Bascom and Bascom (Arch Surg, 137, 2002, 1146-50), by comparison, is a simple operation, resulting in healing in the majority and good cosmesis. METHOD This is a single surgeon series, with the aim of evaluating outcomes for consecutive patients who underwent cleft closure surgery at two centres (St Mark's Hospital, London, and Queen Alexandra Hospital, Portsmouth) between 1995 and 2021 for either extensive, complex or recurrent pilonidal disease. Primary study outcomes that were measured included rate of primary healing, time to complete healing and rate of recurrence. RESULTS Some 714 patients had a cleft closure of whom 656 had documented follow-up. Primary healing occurred in 60.7% (n = 398) rising to 88.5% by 12 weeks (n = 562) and 91.8% by 16 weeks. The remaining patients healed over the following weeks with only 19 wounds failing to heal completely (3%), requiring further surgery to achieve healing. After complete healing 5.3% of patients developed recurrent disease at a median of 12 months. CONCLUSION Cleft closure is an effective operation for pilonidal disease. Overall, 97% of patients healed without further surgery. A 3% failure rate and 5.3% recurrence rate were observed. This technique could be considered as an alternative procedure to complex flaps or midline excision, in extensive, recurrent and unhealed pilonidal disease.

Abstract
BACKGROUND There are reported variations in the intraoperative management of Crohn's disease. This consensus statement aimed to develop a standardised protocol for photographic documentation of intraoperative findings and critical procedural steps in ileocolonic Crohn's disease surgery. METHODS Colorectal surgeons with a specialist interest in minimally invasive surgery and inflammatory bowel disease were invited as committee members to develop a survey on the use of photo-documentation in Crohn's disease surgery. A 15 item survey was developed on ethical considerations and applications of photo-documentation in audit and quality control, research, and training. RESULTS There was strong agreement on the potential application of intraoperative photo-documentation in Crohn's disease for training, research, quality control and tertiary referrals. Reviewers agreed that intraoperative staging required photo-documentation of strictures, skip lesions, perforations, fat wrapping and mesenteric disease. The necessary steps to be photo-documented were very specific to Crohn's disease surgery, such as views of anastomosis and strictureplasties, and extent of resection(s). CONCLUSIONS Our consensus statement identified several items for appropriate intraoperative photo-documentation in Crohn's disease surgery, to be used as an adjunct to accurate annotation of intraoperative findings and procedures.

Abstract
Background: Cryptoglandular anal fistulae can significantly affect patient quality of life (QoL), making it essential to ensure that any study of fistula treatment assesses the impact on QoL. The aim of this systematic review was to evaluate the content validity of Patient-Reported Outcome Measures (PROMs) that assess QoL in patients with a fistula. Methods: MEDLINE, EMBASE, PsycINFO, and Scopus were searched and studies assessing the content validity of patient-reported QoL measurement instruments, or PROM development studies in patients with cryptoglandular anal fistulae, were included. Data were extracted from eligible studies to determine the instruments’ relevance, comprehensiveness, and comprehensibility, and their quality was assessed according to COnsensus-based Standards for the Selection of health Measurement Instruments (COSMIN). Results: Two PROM development studies were identified, both of which described the development of a disease-specific QoL measurement instrument for patients with cryptoglandular anal fistulae. The overall content validity of these instruments was inconsistent and supported by very low-quality evidence. There were no studies assessing the content validity of established QoL measurement instruments in patients with fistulae. Conclusions: This systematic review could not establish the content validity of the available QoL PROMs for patients with anal fistulae, due either to the absence of designated content validity studies or a lack of comprehensiveness of the available PROMs. This highlights an important gap in the literature that needs to be addressed to ensure high-quality outcome assessment in patients with fistulae.

Abstract
There are a range of sphincter-preserving procedures available to treat anorectal fistula, some of which can be precluded, or rendered more optimal by specific features of fistula anatomy. Magnetic resonance imaging (MRI) is the gold standard modality for assessing anorectal fistula. To maximise clinical utility, the MRI report should accurately describe these clinically relevant features. We aimed to develop a minimum dataset for reporting MRI of anorectal fistula, in order to improve the assessment and management of these patients. A longlist of 70 potential items for the minimum dataset was generated through systematic review of the literature. This longlist was presented to radiologists, surgeons and gastroenterologists in an online survey to understand the features that shape current clinical practice. The longlist and survey results were then presented to an expert consensus panel to generate the final minimum dataset through discussion and anonymous voting. The final minimum dataset details the general characteristics, features of the internal and external openings, path of the fistula through the sphincters and any associated extensions and collections that should be described in all MRI reports for anal fistula. Additional surgical and perianal Crohn's disease subsets were developed to indicate the features that aid decision-making for these patients, in addition to a minimum dataset for the clinical request. This study represents a multi-disciplinary approach to developing a minimum dataset for MRI reporting of anal fistula, highlighting the most important features to report that can assist in clinical decision-making. KEY POINTS: • This paper recommends the minimum features that should be included in all MRI reports for the assessment of anal fistula, including Parks classification, number of tracts, features of the internal and external opening, path of the tract through the sphincters, the presence and features of extensions and collections. • Additional features that aid decision-making for surgery or in the presence of Crohn's disease have been identified. • The items that should be included when requesting an MRI are specified.

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
AIM Discussions regarding sex after colorectal and pelvic floor surgery are often overlooked by clinicians. This is the first patient designed and delivered study to explore sexual function and practices after colorectal surgery. The aim was to explore the questions about sex that matter to patients and their partners following colorectal or pelvic floor surgery through a patient and public involvement survey. The results of this work will underpin the creation of a sex patient reported outcome measure. METHODS An anonymous online survey tool (Survey Monkey™) was disseminated via social media (Twitter, Facebook). Thematic analysis was applied to 130 free text comments posted by participants to identify key themes. RESULTS Some 632 individuals completed the survey. Most respondents were women (80% n = 507), 49.5% (n = 312) were married and 14% (n = 87) identified as LGBT+ (lesbian, gay, bisexual and transgender +). Indications for surgery varied: 34% were treated for ulcerative colitis (n = 214); 31% Crohn's (n = 196); 17% (n = 109) cancer; and 17% (n = 110) for perianal fistula. For patients who had a stoma formed (85%, n = 540), over half (51%, n = 324) lived with their stoma for 1-5 years. Respondents reported substantial alterations to their preferences for sexual positions, sexual activity and body confidence following surgery. Most respondents indicated that they were not offered advice about sex by a healthcare professional. CONCLUSIONS The survey showed a substantial impact on the mechanics of sex following colorectal surgery. Few patients were offered preoperative information regarding sex, which has implications for informed consent. This study demonstrates a clear unmet need, voiced by patients, that open dialogue is necessary preoperatively to discuss sexual (dys)function.

Abstract
OBJECTIVE Management of acute severe UC (ASUC) during the novel COVID-19 pandemic presents significant dilemmas. We aimed to provide COVID-19-specific guidance using current British Society of Gastroenterology (BSG) guidelines as a reference point. DESIGN We convened a RAND appropriateness panel comprising 14 gastroenterologists and an IBD nurse consultant supplemented by surgical and COVID-19 experts. Panellists rated the appropriateness of interventions for ASUC in the context of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Median scores and disagreement index (DI) were calculated. Results were discussed at a moderated meeting prior to a second survey. RESULTS Panellists recommended that patients with ASUC should be isolated throughout their hospital stay and should have a SARS-CoV-2 swab performed on admission. Patients with a positive swab should be discussed with COVID-19 specialists. As per BSG guidance, intravenous hydrocortisone was considered appropriate as initial management; only in patients with COVID-19 pneumonia was its use deemed uncertain. In patients requiring rescue therapy, infliximab with continuing steroids was recommended. Delaying colectomy because of COVID-19 was deemed inappropriate. Steroid tapering as per BSG guidance was deemed appropriate for all patients apart from those with COVID-19 pneumonia in whom a 4-6 week taper was preferred. Post-ASUC maintenance therapy was dependent on SARS-CoV-2 status but, in general, biologics were more likely to be deemed appropriate than azathioprine or tofacitinib. Panellists deemed prophylactic anticoagulation postdischarge to be appropriate in patients with a positive SARS-CoV-2 swab. CONCLUSION We have suggested COVID-19-specific adaptations to the BSG ASUC guideline using a RAND panel.

Abstract
BACKGROUND Distal feeding (DF) describes the insertion of a feeding tube into a fistula or stoma to administer a liquid feed into the distal bowel. It is currently used clinically in patients who are unable to absorb enough nutrition orally. This systematic review investigates DF as a therapeutic measure across a spectrum of patients with stomas and fistulae. METHODS A total of 2825 abstracts and 44 full-text articles were screened via OVID. Fifteen papers were included for analysis. Randomised controlled trials, cohort and observational studies investigating DF as a therapeutic measure were included. RESULTS Three feeds were used across the studies-reinfusion of effluent, infusion of prebiotic or a mixture. The studies varied the length of feeding between 24 hours and 61 days, and the mode of feeding, bolus or continuous varied.DF was demonstrated to effectively wean patients from parenteral nutrition in two papers. Two papers demonstrated a significant reduction in stoma output. Three papers demonstrated improved postoperative complication rates with distal feeding regimens, including ileus (2.85% vs 20% in unfed population, p=0.024). One paper demonstrated a reduction in postoperative stool frequency. CONCLUSIONS This review was limited by study heterogeneity and the lack of trial data, and in the patient groups involved, the variability in diet and length of regimen. These studies suggest that DF can significantly reduce stoma output and improve renal and liver function; however, the mechanism is not clear. Further mechanistic work on the immunological and microbiological action of DF would be important.

Abstract
Background Management of anal fistula (AF) remains challenging with many controversies. The purpose of this study was to explore current surgical practice in the management of AF with a focus on technical variations among surgeons. Methods An online survey was conducted by inviting all surgeons and physicians on the membership directory of European Society of Coloproctology and American Society of Colon and Rectal Surgeons. An invitation was extended to others via social media. The survey had 74 questions exploring diagnostic and surgical techniques. Results In March 2018, 3572 physicians on membership directory were invited to take part in the study 510 of whom (14%) responded to the survey. Of these respondents, 492 (96%) were surgeons. Respondents were mostly colorectal surgeons (84%) at consultant level (84%), age ≥ 40 years (64%), practicing in academic (53%) or teaching (30%) hospitals, from the USA (36%) and Europe (34%). About 80% considered fistulotomy as the gold standard treatment for simple fistulas. Endorectal advancement flap was performed using partial- (42%) or full-thickness (44%) flaps. Up to 38% of surgeons performed ligation of the intersphincteric fistula tract (LIFT) sometimes with technical variations. Geographic and demographic differences were found in both the diagnostic and therapeutic approaches to AF. Declared rates of recurrence and fecal incontinence with these techniques were variable and did not correlate with surgeons’ experience. Only 1–4% of surgeons were confident in performing the most novel sphincter-preserving techniques in patients with Crohn’s disease. Conclusions Profound technical variations exist in surgical management of AF, making it difficult to reproduce and compare treatment outcomes among different centers.

Abstract
Crohn's disease is increasingly thought to encompass multiple possible phenotypes. Perianal manifestations account for one such phenotype and represent an independent disease modifier. In its more severe form, perianal Crohn's disease confers a higher risk of a severe and disabling disease course, relapses, hospital admissions and operations. This, in turn, imposes a considerable burden and disability on patients. Identification of the precise manifestation is important, as management is nuanced, with both medical and surgical components, and is best undertaken in a multidisciplinary setting for both diagnosis and ongoing treatment. The introduction of biologic medication has heralded a significant addition to the management of fistulizing perianal Crohn's disease in particular, albeit with modest results. It remains a very challenging condition to treat and further work is required to optimize management in this group of patients.

Abstract
Background Anal fistula occurs in approximately one in three patients with Crohn's disease and is typically managed through a multimodal approach. The optimal surgical therapy is not yet clear. The aim of this systematic review was to identify and assess the literature on surgical treatments of Crohn's anal fistula. Methods A systematic review was conducted that analysed studies relating to surgical treatment of Crohn's anal fistula published on MEDLINE, Embase and Cochrane databases between January 1995 and March 2016. Studies reporting specific outcomes of patients treated for Crohn's anal fistula were included. The primary outcome was fistula healing rate. Bias was assessed using the Cochrane ROBINS‐I and ROB tool as appropriate. Results A total of 1628 citations were reviewed. Sixty‐three studies comprising 1584 patients were ultimately selected in the analyses. There was extensive reporting on the use of setons, advancement flaps and fistula plugs. Randomized trials were available only for stem cells and fistula plugs. There was inconsistency in outcome measures across studies, and a high degree of bias was noted. Conclusion Data describing surgical intervention for Crohn's anal fistula are heterogeneous with a high degree of bias. There is a clear need for standardization of outcomes and description of study cohorts for better understanding of treatment options.

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
INTRODUCTION Surgery is the mainstay of treatment of anal fistulas. Low fistulas are often laid open, but higher fistulas present a more difficult problem. Patient choice centres on a compromise between risk of recurrence and risk of impairment of continence. We aimed to determine the efficacy and safety of fistulotomy at a tertiary referral centre, in particular the additional risk of impairment of continence following fistulotomy of the often recurrent, multiply-operated patients seen. METHODS Patients undergoing surgery under the senior author (RKSP) for an anal fistula during the study period (2005-2006) were identified, and a thorough review of the patients' clinical records was undertaken. Demographic, fistula anatomy, treatment and follow-up data were obtained. RESULTS Eighty-four patients underwent either fistulotomy (50), insertion of permanent loose (drainage) seton (28) or EUA with or without drainage of abscess. Mean length of follow up was 11 months (SD 14.22). In the fistulotomy group, we found an overall success rate of 93 %. Secondary extensions were associated with failure to achieve cure (P = 0.008). Nine patients (20 %) suffered deterioration in continence after surgery. A longer time to referral was associated with impaired final continence. In the group referred from a surgeon in secondary care, 91 % of patients were cured, and continence impairment (mostly minor) rose from 32 % at referral to 40 % after surgery. CONCLUSIONS We have shown that it is safe and reasonable to offer fistulotomy to appropriate patients despite previous surgery and within the tertiary setting. By so doing, a very high rate of healing can be achieved in patients who have previously failed. The additional risk of impairment of continence is around one in five, and in the majority will represent only minor incontinence.

Abstract
Dust storms are frequent in Australia and can have a large impact on the soil resource, the economy and people. There have been few economic studies of the impact of wind erosion worldwide and only one in Australia before this study. While wind erosion impacts on the soil resource at the point of the erosion, the level of economic impact rises as the population and associated infrastructure affected by dust increases. This study estimates the impact on the economy of the state of New South Wales of a single large dust storm called Red Dawn that passed over the eastern coast of Australia on 23 September 2009. Estimates for rural and urban areas are presented with both on- and off-site costs evaluated. The estimated cost is A$299 million (with a range of A$293–A$313 million) with most of the cost being associated with household cleaning and associated activities. The dust storm also impacted on many cities on the coast of the state of Queensland, but their costs are not included in this study. This study demonstrates some, but not all, of the major economic costs associated with wind erosion in Australia. Given the annual average cost of dust storms it is suggested that A$9 million per year would be a conservative estimate of the level of investment required in rural areas for dust mitigation strategies, based on improved land management that could be justified to achieve a positive impact on soil condition and reduce economic losses in rural towns and the more populous coastal cities.

Abstract
BACKGROUND Anti-tumor necrosis factor (TNF) therapy heals many Crohn's disease (CD) anal fistulas clinically but the rate, extent, and durability of deep tissue healing and factors influencing long-term outcome are unknown. METHODS Consecutive patients with CD-related perianal (anal, rectovaginal, anolabial) fistulas treated with infliximab or adalimumab were monitored prospectively both clinically and radiologically using magnetic resonance imaging (MRI). RESULTS Forty-one consecutive patients with CD-related perianal fistulas were treated with infliximab (n = 32) or adalimumab (n = 9; following infliximab failure) in combination with a thiopurine (unless intolerant). Fifty-eight percent of all patients, comprising 66% and 43% of infliximab and adalimumab-treated patients, respectively, demonstrated remission or response at 3 years. Thirty-three percent of infliximab treated patients maintained clinical remission at 3 years. Radiological healing lagged behind clinical remission by a median of 12 months. The likelihood of clinical remission at any time was five times greater in patients who had early clinical response within 6 weeks than those without. A higher number of fistula tracts was associated with reduced clinical remission. All patients who achieved radiological healing maintained healing on infliximab treatment, while only 43% maintained healing after cessation of anti-TNF therapy. CONCLUSIONS Combination anti-TNF and thiopurine therapy provides sustained benefit in patients with perianal CD fistula. Early clinical response is associated with subsequent clinical remission. Radiological healing is slower than clinical healing. Radiologically healed fistula tracts maintain healing on infliximab but can recur after cessation of therapy.

Abstract
The Federal Agricultural Improvement and Reform Act of 1996 required the Secretary of Agriculture to reform federal milk marketing orders. The Secretary carried out this task and issued a final rule on March 31, 1999, that was eventually approved by dairy farmers in a national referendum. However, a temporary restraining order (TRO) was issued on September 28, 1999, that halted the reform process. The TRO was effectively overturned and the reform process restarted when President Bill Clinton signed the Consolidated Appropriations Act of 2000 on November 29, 1999. The final rule as amended consolidates the number of orders, develops a multiple component pricing system that determines new formulas for class prices, and provides a new system for pricing fluid milk based on county-level price differentials. The impact of these changes is to provide more transparency in pricing and improved market signals to farmers. But the new system is also much more vulnerable to changes in dairy commodity prices. The objective of this report is to provide a comprehensive overview of federal order reform and to analyze the impact of recent changes in class price formulas.
