Verkade C, van Tilborg GFAJB, Stijns J, Wasowicz DK, Zimmerman DDE. Distalization of perianal fistulas after loose silicone seton drainage is a myth. Tech Coloproctol 2023; 28:16. [PMID: 38097914 PMCID: PMC10721694 DOI: 10.1007/s10151-023-02882-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 10/25/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND It is often stated that loose seton drainage results in distal migration of a fistula tract in perianal fistula. The aim of the present study was to assess this distalization of trans- and suprasphincteric perianal fistulas after a silicone seton has been inserted. METHODS Consecutive patients who underwent loose seton placement for the management of a transsphincteric or suprasphincteric fistula between January 2016 and December 2021 with a pre- and postoperative magnetic resonance imaging (MRI) were included in the present retrospective study. The height of the external anal sphincter (EAS) and the level of penetration of perianal fistula through the EAS or puborectal muscle (PRM) were determined on MRI. Primary outcome was migration of the fistula tract through the EAS and PRM. RESULTS Thirty-eight patients with perianal fistulas were included. Median height of the EAS was 28 (IQR 25-34) mm before seton placement and 27 (IQR 24-33) mm afterward. Median level of perforation was 32 (IQR 17-40) mm before seton placement and 28 (IQR 17-40) mm afterward (p = 0.37). One fistula (3%) was downgraded from mid to low transsphincteric and was laid open after 14.9 months of loose seton drainage. CONCLUSIONS No statistically significant distalization of complex fistula tracts after loose silicone seton drainage was found. Some complex fistulas may downgrade to a less complex fistula after long-term seton drainage. However, loose silicone seton drainage should not be offered to patients as a treatment option to downgrade a complex fistula to a simple one or even have the hope to heal it.

Surgical treatment trends and outcomes for anal fistula: fistulotomy is still accurate and safe. Results from a nationwide observational study. Tech Coloproctol 2023; 27:909-919. [PMID: 37460829 DOI: 10.1007/s10151-023-02842-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 04/25/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE The aim of the present study was to analyse current surgical treatment preferences for anal fistula (AF) and its subtypes and nationwide results in terms of success and complications. METHODS A retrospective multicentre observational cohort study was conducted. The study period was 1 year (2019), with a follow-up period of at least 1 year. A descriptive analysis of patient characteristics and trends regarding technical options was performed. Univariate and multivariate Cox regression models were used to analyse factors associated with healing and faecal incontinence (FI). RESULTS Fifty-one hospitals were involved, providing data on 1628 patients with AF. At a median follow-up of 18.3 (9.9-28.3) months, 1231 (75.9%) patients achieved healing, while 390 (24.1%) did not; failure was catalogued as persistence in 279 (17.2.0%) patients and as recurrence in 111 (6.8%). On multivariate analysis, factors associated with healing were fistulotomy (OR 5.5; 95% CI 3.8-7.9; p < 0.001), simple fistula (OR 2.1; 95% CI 1.5-2.8; p < 0.001), single tract (HR 1.9; 95% CI 1.3-2.8; p < 0.001) and number of preparatory surgeries (none vs. 3; HR 1.8; 95% CI 1.2-2.8; p = 0.006). Regarding de novo FI, in the multivariate analysis previous anal surgery (OR 1.5, 95% CI 1.0-2.4, p = 0.037), age (OR 1.02, 95% CI 1.00-1.04, p = 0.002) and being female (OR 1.7, 95% CI 1.1-2.5, p = 0.008) were statistically related. CONCLUSIONS Anal fistulotomy is the most used procedure for AF, especially for simple AF, with a favourable overall balance between healing and continence impairment. Sphincter-sparing or minimally invasive sphincter-sparing techniques resulted in lower rates of healing. In spite of their intended sphincter-sparing design, a certain degree of FI was observed for several of these techniques.

Abstract
BACKGROUND Anal fistulas are mainly treated via surgery. They can be difficult to treat without surgical intervention. Numerous procedures, such as fistulectomy and fistulotomy, are performed to treat anal fistulas and achieve good effects. However, the wounds created through fistulectomy and fistulotomy take a long time to heal. Therefore, a multicentre randomised controlled trial (RCT) is proposed to study the efficacy of one-stage shaped skin grafting at the surgical wound to heal low simple intersphincter anal fistulas. METHODS This study is a multicentre, hospital-based RCT. It will be performed at three hospitals. A total of 104 patients with low simple intersphincter anal fistulas who meet the inclusion criteria will be included in this trial and will be allocated randomly to two groups (test and control groups). The patients in the test group will receive one-stage anal fistulotomy surgery combined with shaped skin grafting, and those in the control group will undergo anal fistulotomy only. All the operations will be performed by attending colorectal surgeons or surgeons of a higher level. Effectiveness and safety indicators will be observed, recorded and analysed. DISCUSSION Anal fistulotomy can heal low simple intersphincter anal fistulas effectively and safely with a low recurrence rate. Skin grafts promote wound epithelisation significantly. We believe that skin grafting can treat low simple intersphincter fistulas with a short healing time. TRIAL REGISTRATION Chinese Clinical Trial Register, ChiCTR2000039174.

Surgery of Simple and Complex Anal Fistulae in Adults: A Review of the Literature for Optimal Surgical Outcomes. Cureus 2023; 15:e35888.

Abstract
Anal fistulas are common anorectal conditions, and surgery is the primary treatment option. In the last 20 years of literature, there exist a large number of surgical procedures, especially for the treatment of complex anal fistulas, as they present more recurrences and continence problems than simple anal fistulas. To date, there are no guidelines for choosing the best technique. We conducted a recent literature review, mainly the last 20 years, based on the PubMed and Google Scholar medical databases, with the goal of identifying the surgical procedures with the highest success rates, lowest recurrence rates, and best safety profiles. Clinical trials, retrospective studies, review articles, comparative studies, recent systematic reviews, and meta-analyses for various surgical techniques, as well as the latest guidelines of the American Society of Colon and Rectal Surgeons, the Association of Coloproctology of Great Britain and Ireland, and the German S3 guidelines on simple and complex fistulas were reviewed. According to the literature, there is no recommendation for the optimal surgical technique. The etiology, complexity, and many other factors affect the outcome. In simple intersphincteric anal fistulas, fistulotomy is the procedure of choice. In simple low transsphincteric fistulas, the patient's selection is crucial in order to perform a safe fistulotomy or another sphincter-saving technique. The healing rate in simple anal fistulas is higher than 95% with low recurrence and without significant postoperative complications. In complex anal fistulas, only sphincter-saving techniques should be used; the optimal outcomes are obtained by the ligation of the intersphincteric fistulous tract (LIFT) and rectal advancement flaps. Those techniques assure high healing rates of 60-90%. The novel technique of the transanal opening of the intersphincteric space (TROPIS) is under evaluation. The novel sphincter-saving techniques of fistula laser closure (FiLac) and video-assisted anal fistula treatment (VAAFT) are safe, with reported healing rates ranging from 65% to 90%. Surgeons should be familiar with all sphincter-saving techniques in order to face the variability of the fistulas-in-ano. Currently, there is no universally superior technique that can treat all fistulas.

Would Surgeons Like to Be Submitted to Anal Fistulotomy? An International Web-Based Survey. J Clin Med 2023; 12:jcm12030825. [PMID: 36769474 PMCID: PMC9918049 DOI: 10.3390/jcm12030825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 01/15/2023] [Accepted: 01/18/2023] [Indexed: 01/22/2023] Open
Abstract
Traditional fistulotomy is the most performed surgical procedure in anal fistula surgery. We conducted an international online survey to explore colorectal surgeons' opinions and preferences on fistulotomy. Considering the healing and continence impairment rates reported in the literature, surgeons were invited to answer as a hypothetic patient susceptible to being submitted to fistulotomy for low and high anal fistula. A total of 767 surgeons completed the survey from 72 countries. The majority of respondents were consultants, having treated more than 20 anal fistulas in the last year. Most of them declared that anal fistula would be able to negatively affect quality of life and would be worried/anxious about it. Taking into account all aspects, 87.5% and 37.8% of respondents would agree to be treated with a fistulotomy in case of a low and high fistula, respectively, with an acceptance rate that varied worldwide. At multivariate analysis, factors correlated to the acceptance of anal fistulotomy were male gender (p = 0.003), practice of less than 20 fistula operations during last year (p = 0.020), and low fistula (p < 0.001). Surgeons recognized the extreme complexity of this approach. This study highlighted the necessity of an accurate patients' selection and the adoption of alternative strategy to reduce the risk of anal continence impairment.

Abstract
Abstract
Objective Despite all the technological advances, successful management of complex fistula-in-ano is still a challenge due to recurrence and incontinence. The present study evaluates the outcomes of a novel technique, Interception of Fistula Track with Application of Ksharasutra (IFTAK) in terms of success rate and degree of incontinence.
Methods In the present prospective study, 300 patients with complex fistula-in-ano were treated by the IFTAK technique, whose surgical steps include: incision at the anterior or posterior midline perianal area, identification and interception of the fistulous track at the level of the external sphincter, rerouting the track (and extensions) at the site of interception, and application of a ksharasutra (medicated seton) in the proximal track (from the site of interception to the internal opening) that is laid open gradually, with the resulting wound healing with minimum scarring. The distal track is allowed to heal spontaneously.
Results There were 227 trans-sphincteric and 73 intersphincteric varieties of fistula with supralevator extension in 23 cases, of which 130 were recurrent fistulas, 29 had horseshoe track, while 25 had blind fistula with no cutaneous opening. The mean duration of the ksharasutra application was 8.11 ± 3.86 weeks with an overall success rate of 93.33% at the 1-year follow-up. A total of 3.67% of the cases reported with a mild impairment of continence on the Wexner incontinence scoring system. Pre- and postoperative anal manometry evaluation showed minimal reduction in median basal and squeeze pressures.
Conclusion The IFTAK technique is a minimally invasive, daycare surgical procedure for the management of complex fistula-in-ano with low recurrence and minimal sphincter damage.

A systematic review and meta-analysis. Colorectal Dis 2021; 23:3073-3089. [PMID: 34623747 DOI: 10.1111/codi.15945] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 06/22/2021] [Accepted: 07/19/2021] [Indexed: 12/23/2022]
Abstract
AIM This systematic review aimed to assess the outcomes of fistulotomy or fistulectomy and immediate sphincter repair (FISR) in relation to healing, incontinence and sphincter dehiscence both overall and in patients with high anal fistulae. METHODS Medline, Embase and The Cochrane library were searched for studies of patients undergoing FISR for anal fistula. Data regarding healing, continence and sphincter dehiscence were extracted overall and for high anal fistulae. The DerSimonian-Laird random-effects method was used for pooled analysis, heterogeneity between studies was assessed based on the significance of between-study heterogeneity, and on the size of the I2 value. Risk of bias was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa scale. RESULTS We identified 21 studies evaluating 1700 patients. Pooled analysis of healing reached 93% (95% CI: 91%-95%, I2 = 51% p-value for heterogeneity = 0.004), with continence disturbance and worsening continence reaching 11% (95% CI: 6%-18%, I2 = 87% p < 0.001) and 8% (95% CI: 4%-13%, I2 = 74% p < 0.001), respectively. Subgroup analysis according to fistula height could only be conducted on limited data. Pooled healing in high anal fistulae was 89% (95% CI: 84%-94%, I2 = 76% p < 0.001), 16% suffered disturbance of continence (95% CI: 7%-27%, I2 = 89% p < 0.001), 8% worsening continence from baseline (95% CI: 2%-16%, I2 = 80% p < 0.001) and 2% suffered sphincter dehiscence (95% CI: 0%-10%, I2 = 89% p < 0.001). CONCLUSION The evidence suggests FISR is a safe, effective procedure. However, data are limited by inconsistencies in reporting of continence and definition of fistula height, particularly high anal fistulae. Significant heterogeneity means that outcomes in high fistulae remain uncertain.

VAAFT for complex anal fistula: a useful tool, however, cure is unlikely. Tech Coloproctol 2021; 25:1115-1121.

Abstract
BACKGROUND Therapeutic options for complex anal fistula (CAF) are limited. Video-assisted anal fistula treatment (VAAFT) allows examination of these anatomically complex fistulae from within. The aim of the present study was to evaluate outcomes of VAAFT for a series of CAF. METHODS A retrospective study was conducted on consecutive patients at a single centre with complex anal cryptoglandular and Crohn's fistulae managed with VAAFT from June 2016 to June 2019. CAF was diagnosed as high intersphincteric/transsphincteric tract, multiple/secondary tracts, horseshoe or anovaginal fistulae. Patients were treated with 'therapeutic intent' if the internal opening was closed at the time of ablation and 'diagnostic/staged/palliative' VAAFT if there was no ablation/partial treatment/ablation-only, respectively. Symptom improvement was a reduction in reported pain, discharge, or pad use. RESULTS Eighty-four patients (73 cryptoglandular, 11 Crohn's, M:F 2.5:1, median age 43 [22-77] years), underwent 105 VAAFT procedures. Twenty patients had > 1 VAAFT. Median follow-up was 8 (1-46) months. 40 (48%) had multiple or secondary tracts; an additional 16 (19%) had horseshoe and 3 (4%) anovaginal fistulae. Of the 84 patients, 19 [16/73 (22%) cryptoglandular and 3/11 (27%) Crohn's fistulae] healed. 34 (40%) unhealed reported improved symptoms; 23 (27%) no improvement; and 6 (7%) were worse. Sixteen (19%) had CAF > 5 years of whom none healed, albeit 50% reported symptom improvement. Five patients (6%) developed faecal incontinence: 2 temporary, 1 to flatus only and 1 to liquid and 1 to solid, all managed conservatively. CONCLUSIONS VAAFT is a useful minimally invasive procedure for complex fistula with no other minimally invasive options. Complete healing is rare, and, although symptoms can be improved in a number of cases, there is a small risk of incontinence.

Heterogeneity in outcome selection, definition and measurement in studies assessing the treatment of cryptoglandular anal fistula: findings from a systematic review. Tech Coloproctol 2021; 25:761-830. [PMID: 33963945 PMCID: PMC8187216 DOI: 10.1007/s10151-021-02452-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Accepted: 04/15/2021] [Indexed: 12/12/2022]
Abstract
Background Treatment for cryptoglandular anal fistula (AF) is challenging and a lack of uniform outcomes in the literature prevents direct comparison of treatments. This can be addressed by developing a core outcome set, a standardised set of outcomes reported in all interventional studies for a specific condition. The aim of this systematic review is to assess the range of outcomes, their definitions, and the measurement instruments currently utilised in interventional studies for adult patients with AF. This will inform the development of an AF core outcome set. Methods Medline, Embase and The Cochrane Library were searched to identify all patient- and clinician-reported outcomes in studies assessing medical, surgical or combination treatment of adult patients with AF published from January 2008 to May 2020. The resulting outcomes were categorized according to the Core Outcome Measurement in Effectiveness Trials (COMET) taxonomy to better understand their distribution. Results In total, 155 studies were included, 552 outcomes were extracted, with a median of three outcomes (interquartile range 2–5) per study. Only 25% of studies demonstrated high-quality outcome reporting. The outcomes were merged into 52 unique outcomes and structured into four core areas and 14 domains, with the majority in the domain of physiological or clinical (gastrointestinal) outcomes. The most commonly reported outcomes were healing (77%), incontinence (63%), and recurrence (40%), with no single outcome assessed across all studies. There was a wide variation in outcome definitions and measurement instruments used. Conclusions There is substantial heterogeneity in outcomes, definitions, and measurement instruments reported in interventional studies for cryptoglandular anal fistula. This emphasises the need for standardised outcome reporting and measurement.

Abstract
BACKGROUND Surgical treatment of anal fistulas is still a challenge. The aims of this study were to evaluate the adoption and healing rates for the different surgical techniques used in Italy over the past 15 years. METHODS This was a multicenter retrospective observational study of patients affected by simple and complex anal fistulas of cryptoglandular origin who were surgically treated in the period 2003-2017. Surgical techniques were grouped as sphincter-cutting or sphincter-sparing and as technology-assisted or techno-free. All patients included in the study were followed for at least 12 months. RESULTS A total of 9,536 patients (5,520 simple; 4,016 complex fistulas) entered the study. For simple fistulas, fistulotomy was the most frequently used procedure, although its adoption significantly decreased over the years (P < .0005), with an increase in sphincter-sparing approaches; the overall healing rate in simple fistulas was 81.1%, with a significant difference between sphincter-cutting (91.9%) and sphincter-sparing (65.1%) techniques (P = .001). For complex fistulas, the adoption of sphincter-cutting approaches decreased, while sphincter-sparing techniques were mildly preferred (P < .0005). Moreover, there was a significant trend toward the use of technology-assisted procedures. The overall healing rate for complex fistulas was 69.0%, with a measurable difference between sphincter-cutting (81.1%) and sphincter-sparing (61.4%; P = .001) techniques and between techno-free and technology-assisted techniques (72.5% and 55.0%, respectively; P = .001). CONCLUSION Surgical treatment of anal fistulas has changed, with a trend toward the use of sphincter-sparing techniques. The overall cure rate has remained stable, even if the most innovative procedures have achieved a lower success rate.

Ng KS, Kwok AMF, Young CJ. Factors associated with healing, reoperation and continence disturbance in patients following surgery for fistula-in-ano. Colorectal Dis 2020; 22:2204-2213. [PMID: 32947650 DOI: 10.1111/codi.15372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 07/22/2020] [Indexed: 02/08/2023]
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
Objective: The aim of our study was to compare the success rates of suture selection, recovery times and pain associated with local wound infection and seton placement in patients undergoing cutting seton placement for complex anal fistula. Methods: The study included a total of 90 patients who were admitted with the diagnosis of complex anal fistula between January 2015 and July 2018. Results: The first session and other revision appointments demonstrated that the number of patients who required fistulotomy was significantly higher in group-1 as the seton failed to complete the transection (p = 0.001). When the patients were asked to rate pain for 3 different conditions according to numeric rating scale (NRS), the patients in group-2 had significantly higher pain in all 3 cases compared to the patients in group-1 (p 0.001). The impact of the suture material on local infection was examined and it was determined that the results of cultures for seton material were significantly more positive in group-1 (p = 0.001). Conclusions: We conclude that a multi-stage tight seton placement with silk material can lead to satisfactory results by aiming to shorten the cutting time of silk seton.

Abstract
PURPOSE We determined the outcomes of patients undergoing video-assisted anal fistula treatment (VAAFT) for fistulain-ano at the Philippine General Hospital. METHODS Twenty consecutive adult patients who underwent the VAAFT procedure from 2016-2018 were included in this investigation. Information detailing baseline demographic and clinical data, fistula type and classification, and previous surgeries were retrieved from in-hospital and operative records. Operative time, identification of the internal opening, method of internal opening closure, and occurrence of immediate postoperative complications were determined. The status of the fistula was assessed at one month, 3 months, and 6 months postoperatively based on outpatient follow-up records. The primary outcomes were healing rate and recurrence rate. Secondary outcomes were 30-day morbidity, postoperative complications, and incontinence using the Wexner score. RESULTS Eighteen patients (90%) had a preoperative diagnosis of complex fistula, and 13 patients (65%) had undergone a previous fistula surgery. Primary healing rate was 55% at 1 month, 63.16% at 3 months, and 78.95% at 6 months postoperatively. Eighteen patients (94.74%) maintained continence (Wexner score = 0) at 6 months. CONCLUSION Our study results suggest that VAAFT is a safe, minimally invasive technique for treatment of anal fistula and can preserve anal sphincter function. The technique has an acceptable healing rate with minimal complications.

Abstract
BACKGROUND The aim of this study was to evaluate the safety and long-term efficacy of fistulotomy and primary sphincteroplasty (FIPS). Secondary endpoints were its impact on postoperative continence status and patients' satisfaction. METHODS A retrospective study was conducted on patients with cryptoglandular anal fistula (AF) who had FIPS between June 2006 and May 2017. Patients were evaluated with standardized telephone interviews and clinical/instrumental assessment. Main outcome measures included fistula healing rate, continence status, and patient satisfaction. Incontinence was defined as an inability to hold either gas, liquid, or solid stools, as well as postdefecation soiling, and was measured by the Cleveland Clinic fecal incontinence score. Patient satisfaction was evaluated by an 11-point numeric rating scale. RESULTS There were 203 patients (139 males; mean age: 48.7 years) who had FIPS. The overall healing rate was 93% (188 patients) with a mean follow-up period of 56 ± 31 months. Half of the total cohort (51%) had a complex fistula. Preoperatively, 8 (4%) patients complained of postdefecation soiling and 2 (1%) of gas incontinence. Postoperatively, 26 (13%) patients had continence impairment (de novo n = 24), mainly consisting of postdefecation soiling (10%). In univariate analysis, patients with recurrent (RR 6.153 95% CI 2.097-18.048; p = 0.002) or complex (RR 3.005 95% CI 1.203-7.506; p = 0.012) AF and those with secondary tracts (RR 8.190 95% CI 2.188-30.654; p = 0.004) or previous set on drainage (RR 5.286 95% CI 2.235-12.503; p = 0.0001) were at higher risk of incontinence. In multivariate analysis, no significant predictors were found, although fistula complexity approached statistical significance (RR 5.464 95% CI 0.944-31.623; p = 0.050). The mean patient satisfaction numeric rating scale was 9.3 ± 1.6. Lower satisfaction rates were found in patients with transphincteric (p = 0.011) or complex (p = 0.0001) AF, with secondary tracts (p = 0.041) or previous seton drainage (p = 0.008), and in those with postoperative continence impairment (p = 0.0001). Postoperative onset of incontinence was the only significant factor in multivariate analysis (p = 0.0001). CONCLUSIONS FIPS should be considered a valid therapeutic option for selected AF. However, the risk of postoperative minor fecal incontinence exists, and should be discussed during preoperative patient counselling.

Abstract
INTRODUCTION This study aimed to evaluate the applicability, safety, results, and functional performance of Permacol™ collagen paste injection in patients with an anal fistula. METHODS Thirty-one patients with anal fistula underwent Permacol™ collagen paste injection between February 2015 and February 2017. The patients were followed up for a total of 12 months with recovery conditions monitored at intervals of 3, 6, and 12 months. Preoperative insertion of seton was performed in 15 patients for a period of 6-8 weeks and 2 patients for a period of 12 weeks. RESULTS A trans-sphincteric anal fistula was present in 20 patients and an intersphincteric fistula was present in 11 patients. There was a recurrence in 7 patients (22.5%): 1 patient (3.2%) after 1-month follow-up, 3 patients (9.7%) after 3-month follow-up, 2 patients (6.5%) after 6-month follow-up, and 1 patient (3.2%) after 12-month follow-up. A complete recovery was observed in 24 (77.5%) patients after a 12-month follow-up. The mean Fecal Incontinence Severity Index score was 0.29 ± 0.64 preoperatively and 0.55 ± 1.03 after 12 months. CONCLUSION In this study, we show that treatment of patients with an anal fistula by injection of Permacol™ is a safe and successful method that does not compromise continence.

Abstract
AIM Due to fear of incontinence, fistulotomy perhaps remains highly underutilized. The aim was to analyze the efficacy of fistulotomy in a large cohort, to assess the magnitude of underutilization of fistulotomy by current classifications and to identify the subgroup in whom the fistulotomy should be done. METHODS All consecutive operated patients of fistula-in-ano were included in the study retrospectively. The fistulas were classified as per existing classifications-Parks, St James University Hospital (SJUH) and Garg classification. Smaller grades of each classification (Parks I, SJUH I-II, Garg I-II) were expected to be simple fistulas and thus amenable to fistulotomy. Objective incontinence scores were done preoperatively and postoperatively. RESULTS 675 patients were operated over a 5.5 year period (median-27 months). 25 patients were excluded. Fistulotomy was done in 353/650 (54.3%) patients and sphincter-saving procedures (SSP) performed in 297/650 (45.7%) patients. After fistulotomy, 346/353 (98%) fistulas healed after the first operation. Seven patients with recurrent fistula were cured after a repeat fistulotomy surgery. Thus the overall healing rate was 353/353 (100%). There was no significant change in continence scores. The 353 fistulotomy patients were classified as per different classifications- Parks (I-225,II-112,III-16,IV-0), SJUH(I-138,II-87,III-47,IV-65,V-16) and Garg (I-188,II-165,III-0,IV-0,V-0). 123 (36.3%) patients who could undergo fistulotomy successful were erroneously classified as complex fistula by Parks and SJUH classifications. Garg classification accurately identified all 353/353 (100%) patients were amenable to fistulotomy. CONCLUSIONS Fistulotomy is a safe procedure with remarkably high success rate (100%) and is gold-standard in majority of patients (>50%). Parks and SJUH classifications are inaccurate in selecting patients for fistulotomy. Garg classification predicts amenability to fistulotomy with very high accuracy.

Abstract
BACKGROUND The surgical treatment of complex anal fistulae, particularly those involving a significant portion of the anal sphincter in which fistulotomy would compromise continence, is challenging. Video-assisted anal fistula treatment (VAAFT), fistula tract laser closure (FiLaC™) and over-the-scope clip (OTSC®) proctology system are all novel sphincter-sparing techniques targeted at healing anal fistulae. In this study, all published articles on these techniques were reviewed to determine efficacy, feasibility and safety. METHODS A systematic search of major databases was performed using defined terms. All studies reporting on experience of these techniques were included and outcomes (fistula healing and safety) evaluated. RESULTS Eighteen studies (VAAFT-12, FiLaC™-3, OTSC®-3) including 1245 patients were analysed. All were case series, and outcomes were heterogeneous with follow-up ranging from 6 to 69 months and short-term (< 1 year) healing rates of 64-100%. Morbidity was low with only minor complications reported. There was one report of minor incontinence following the first reported study of FiLaC™, and this was treated successfully at 6 months with rubber band ligation of hypertrophied prolapsed mucosa. There are inconsistencies in the technique in studies of VAAFT and FiLaC™. CONCLUSIONS All three techniques appear to be safe and feasible options in the management of anal fistulae, and short-term healing rates are acceptable with no sustained effect on continence. There is, however, a paucity of robust data with long-term outcomes. These techniques are thus welcome additions; however, their long-term place in the colorectal surgeon's armamentarium, whether diagnostic or therapeutic, remains uncertain.

Abstract
BACKGROUND Optimal surgical treatment for anal fistula should result in healing of the fistula track and preserve anal continence. The aim of this study was to evaluate Permacol™ collagen paste (Covidien plc, Gosport, Hampshire, UK) injection for the treatment of complex anal fistulas, reporting feasibility, safety, outcome and functional results. METHODS Between May 2013 and December 2014, 21 consecutive patients underwent Permacol paste injection for complex anal fistula at our institutions. All patients underwent fistulectomy and seton placement 6-8 weeks before Permacol™ paste injection. Follow-up duration was 12 months. RESULTS Eighteen patients (85.7%) had a high transsphincteric anal fistula, and three female patients (14.3%) had an anterior transsphincteric fistula. Fistulas were recurrent in three patients (14.3%). Seven patients (33%) had a fistula with multiple tracts. After a follow-up of 12 months, ten patients were considered healed (overall success rate 47.6%). The mean preoperative FISI score was 0.33 ± 0.57 and 0.61 ± 1.02 after 12 months. CONCLUSIONS Permacol™ paste injection was safe and effective in some patients with complex anal fistula without compromising continence.

Abstract
Fistula-in-ano has been managed by a number of techniques and there remains no consensus on the most appropriate management for all patients. The mainstay of any treatment balances the need to control sepsis vs the risk of potential incontinence post-intervention. Management should focus on the primary source of sepsis.

Abstract
BACKGROUND AND AIM Fistula-in-ano is a common problem among patients with Crohn's disease and carries significant morbidity. We aimed to study the outcomes of surgical treatment of fistula-in-ano after fistulotomy or seton placement in patients with perianal fistulizing Crohn's disease. MATERIAL AND METHODS A retrospective observational study of 59 patients diagnosed with Crohn's disease, who were treated surgically for fistula-in-ano between 2010 and 2014 in our department. The assessment of disease complexity included a detailed physical examination, magnetic resonance imaging of the rectum, and examination under anesthesia. Outcomes for analysis included wound healing rate and postoperative incontinence. RESULTS High transsphincteric fistula was found in 44% of the patients, while mid or low transsphincteric fistulas were found in 51%. Three women (5%) had a rectovaginal fistula. All patients with high transsphincteric fistulas were treated with loose seton placement. Patients with mid- or low-level transsphincteric fistula were offered either fistulotomy or seton placement based on the clinical evaluation. The mean follow-up duration was 1.6 ± 1.1 years. In terms of recurrence, one patient treated with seton placement presented with recurrence 6 months after seton removal and one patient with fistulotomy failed to achieve wound healing. Minor incontinence was found in six patients treated with fistulotomy and in three patients treated with seton placement; however, this difference was not significant (chi-square = 1.723, df = 1, Monte-Carlo: p = 0.273). CONCLUSION Fistulotomy could achieve good results in terms of wound healing and incontinence in strictly selected patients with Crohn's disease suffering from low-lying transsphincteric fistulae. For more high-lying or complicated fistulae, seton placement is more appropriate. For high transsphincteric fistulae, the only option is placement of loose seton.

Abstract
This study evaluates low transsphincteric anal fistula managed by serial setons and interval fistulotomy, with attention to healing without recurrence and preservation of continence. Following Institutional Review Board approval, consecutive anal fistula operations performed by a single surgeon from January 1, 2009 to December 31, 2013 were retrospectively reviewed using electronic medical records and telephone interviews for patients lost to follow up. Of the 71 patients, 26 (37%) had low transsphincteric fistula (23 males and 3 females; mean age: 46 years), treated at our institution by seton placement followed by interval surgical muscle cutting and subsequent seton replacement or final fistulotomy. Of the 26 patients, 22 (85%) were initially referred due to previous failed treatment, with a 30.6 month mean duration of fistula prior to referral and a mean of 2.2 (range: 0 -6) prior anorectal surgeries. At a mean follow-up of 11.9 months, none of the 21 patients experienced recurrence or fecal incontinence. Serial seton with interval muscle-cutting sphincterotomy followed by complete fistulotomy is an effective treatment for the management of patients who are either initially seen for low transsphincteric fistula, or referred after failed anorectal surgery for that condition.

Abstract
Complex anal fistulas require careful evaluation. Prior to any attempts at definitive repair, the anatomy must be well defined and the sepsis resolved. Several muscle-sparing approaches to anal fistula are appropriate, and are often catered to the patient based on their presentation and previous repairs. Emerging technologies show promise for fistula repair, but lack long-term data.

Abstract
INTRODUCTION Complex anal fistulas are responsible for pain, faecal incontinence and impaired quality of life. The rectal mucosa advancement flap (RMAF) procedure to cover the internal opening of the fistula remains a strategy of choice. However, a new procedure for closing anal fistulas is now available with the use of a nitinol closure clip (OTSC Proctology, OVESCO), which should ensure a better healing rate. This procedure is currently becoming more widespread, though without robust scientific validation, and it is therefore essential to carry out a prospective evaluation in order to determine the efficacy and safety of this new medical device for complex anal fistulas. METHODS AND ANALYSIS The FISCLOSE trial is aimed at evaluating the efficacy and safety of a nitinol closure clip compared to the RMAF procedure for the management of complex anal fistulas. This trial is a prospective, randomised, controlled, single-blind, bicentre and interventional study. Patients (n=46 per group) will be randomly assigned for management with either a closure clip or RMAF. The main objectives are to improve the healing rate of the anal fistula, lessen the postoperative pain and faecal incontinency, enhance the quality of life, and lower the number of reinterventions and therapeutic management costs. The primary outcome is the proportion of patients with a healed fistula at 3 months. The secondary outcomes are anal fistula healing (6 and 12 months), proctological pain (visual analogue scale), the faecal incontinence score (Jorge and Wexner questionnaire), digestive disorders and quality of life (Gastrointestinal Quality of Life Index and Euroqol EQ5D-3 L) up to 1 year. ETHICS AND DISSEMINATION The study was approved by an independent medical ethics committee 1 (IRB00008526, CPP Sud-Est 6, Clermont-Ferrand, France) and registered by the competent French authority (ANSM, Saint Denis, France). The results will be disseminated in a peer-reviewed journal and presented at international congresses. TRIAL REGISTRATION NUMBER NCT02336867; pre-result.

Abstract
AIM The aim of the study was to evaluate the impact of three-dimensional endoanal ultrasound (3D-EAUS) on postoperative outcome in patients with anal fistula. METHOD This prospective study compared clinical and functional outcomes of patients with and without preoperative 3D-EAUS examination 1 year after anal fistula surgery. Patients were prospectively followed and evaluated by a standardized protocol including physical examination, the Wexner Incontinence Score (WIS) and anorectal manometry, at baseline and 1 year after surgery. RESULTS A total of 196 patients were enrolled. There were no significant differences in demographic and operative parameters, except for operation time, between the two groups. At 1 year follow-up, the overall recurrence rates were 8.8% (9/102) in the 3D-EAUS group and 13.8% (13/94) in the examination under anaesthesia (EUA) group. In the subgroup of patients with complex fistulae, the recurrence rate was numerically lower in the 3D-EAUS group (12.8% vs 22.5%; P = 0.26). The WIS in the EUA group significantly worsened (0.35 ± 0.94 vs 1.07 ± 1.59; P = 0.003) with a decreased the number of fully continent patients (82.5% vs 55%; P = 0.008) while neither the WIS nor the proportion of fully continent patients changed in the 3D-EAUS group. Fewer patients in the 3D-EAUS group developed incontinence postoperatively (6.7% vs 33.3%; P = 0.012) and they had better maximum resting pressure and maximum squeeze pressure than the EUA group. CONCLUSIONS Preoperative use of 3D-EAUS had a favourable impact on the outcome of surgical treatment for anal fistulae, especially in those with complex anal fistula. It should be routinely used in the clinical setting.

Abstract
BACKGROUND Surgical management of cryptoglandular fistulas is a challenge because the consequences of anal surgery potentially include fecal incontinence and impaired quality of life. OBJECTIVE To assess factors associated with fecal incontinence after surgery for simple and complex cryptoglandular fistulas and to determine the impact of incontinence on quality of life. DESIGN The design is retrospective and cross-sectional. SETTINGS This study was conducted at an academic tertiary center and at a private center specializing in proctologic surgery. PATIENTS All patients who underwent preoperative endoanal ultrasound for cryptoglandular fistula between 2002 and 2012. MAIN OUTCOME MEASURES A questionnaire was sent out in October 2013 to evaluate incontinence (Wexner-score) and its impact on quality of life (FIQL). Variables tested for association were patient demographics, fistula type, number of incised abscesses (0, 1, >1), number of fistulotomies (0, 1, >1) and number of sphincter-sparing procedures (0, 1, >1). RESULTS Of the 141 patients participating, 116 (82%; 76 men, 40 women) returned all the questionnaires. Median follow-up from the first perianal fistula surgery was 7.8 years (range, 2.1-18.1 years). Thirty-nine patients (34%) experienced incontinence. Surgical fistulotomy, multiple abscess drainages and a high transsphincteric or suprasphincteric fistula tract were associated with incontinence. As compared to simple fistula (Wexner score, 1.2 [SD, 2.1]), incontinence was worse after surgery for complex fistula (Wexner score, 4.7 [SD, 6.2], p = 0.001), as were quality of life elements, including lifestyle (p = 0.030), depression (p = 0.077) and embarrassment (p < 0.001). LIMITATIONS Mainly retrospective design without a standardized treatment protocol. CONCLUSION Surgical fistulotomy is the strongest risk factor for fecal incontinence. The severity of incontinence increases with the complexity of the fistula, negatively influencing quality of life. Special attention should be paid to these patients so as to mitigate symptoms later in life. A shift to sphincter-sparing procedures appears warranted.

Abstract
AIM: To investigate the anal sphincter and rectal factors that may be involved in fecal incontinence that develops following fistulotomy (FIAF).
METHODS: Eleven patients with FIAF were compared with 11 patients with idiopathic fecal incontinence and with 11 asymptomatic healthy subjects (HS). All of the study participants underwent anorectal manometry and a barostat study (rectal sensitivity, tone, compliance and capacity). The mean time since surgery was 28 ± 26 mo. The postoperative continence score was 14 ± 2.5 (95%CI: 12.4-15.5, St Mark’s fecal incontinence grading system).
RESULTS: Compared with the HS, the FIAF patients showed increased rectal tone (42.63 ± 27.69 vs 103.5 ± 51.13, P = 0.002) and less rectal compliance (4.95 ± 3.43 vs 11.77 ± 6.9, P = 0.009). No significant differences were found between the FIAF patients and the HS with respect to the rectal capacity; thresholds for the non-noxious stimuli of first sensation, gas sensation and urge-to-defecate sensation or the noxious stimulus of pain; anal resting pressure or squeeze pressure; or the frequency or percentage of relaxation of the rectoanal inhibitory reflex. No significant differences were found between the FIAF patients and the patients with idiopathic fecal incontinence.
CONCLUSION: In patients with FIAF, normal motor anal sphincter function and rectal sensitivity are preserved, but rectal tone and compliance are impaired. The results suggest that FIAF is not due to alterations in rectal sensitivity and that the rectum is more involved than the anal sphincters in the genesis of FIAF.
