Abstract
BACKGROUND Treatment of fistula-in-ano with fistula laser closure (FiLaC®) is a sphincter-saving procedure indicated for patients with complex anal fistulas. The aim of our study was to evaluate the clinical results of a 10-year experience with FiLaC®. METHODS Data from patients with cryptoglandular anal fistula who underwent laser closure with FiLaC® in June 2009-May 2019 were evaluated. The primary study endpoint was healing rate. Secondary endpoints were evaluation of morbidity and assessment of possible predictive factors of failure. RESULTS Out of a total of 180 patients, 5 had been lost to follow-up. 175 patients [m:f: 115:60; median age 49 years (range18-81 years)] with cryptoglandular fistulas treated with FiLaC® were included in the study. Fistulas were transphincteric in 152 (86.8%) cases, intersphincteric in 18 (10.3%), and suprasphincteric in 5 (2.9%). A seton or draining silicon loop was placed in 142 (81.8%) patients at a median of 14 weeks (range10-28 weeks) prior to FiLaC®. At median follow-up of 60 months (range 9-120 months), the overall primary healing rate was 66.8% (117/175). Thirty-eight patients (21.7%) failed to heal. Twenty out of 175 (11.4%) patients had recurrence at median follow-up of 18 months (range 9-50 months). Patients in whom a seton/loop was inserted for drainage at the first-stage procedure had a statistically significant higher rate of success (100/142, 70.4% vs. 17/33, 51.5%, respectively; p 0.0377; odds ratio 0.45). Forty-eight patients were reoperated on at a median of 15 months (range 12-20 months) after laser treatment. Twenty-six underwent redo laser closure with FiLaC®, and 12 of them healed (46%), for a secondary success rate of 73.7%. CONCLUSIONS Longer follow-up confirms the efficacy of FiLaC® in the treatment of complex anal fistulas. Its use and implementation should be encouraged.

Abstract
AIM Complex perianal fistulas pose a challenge to the surgeon since the fistulous tract must be eliminated without impairing continence. Although without strong scientific evidence, some bibliography has demonstrated the efficacy of some sealants in the treatment of anal fistulas. We aimed to assess the feasibility and safety of calcium alginate hydrogel injections into the fistulous tract as treatment for trans-sphincteric cryptoglandular fistulas. METHODS A prospective, single-centre, case series of this novel technique was conducted in a level 3 Spanish hospital, including patients diagnosed with trans-sphincteric perianal fistulas and treated with a calcium alginate hydrogel sealant. A strict follow-up was performed by an independent surgeon at 1, 3, 6 and 12 months. The main outcome measures were feasibility, safety (number of adverse events) and efficacy of the treatment. RESULTS Twenty patients were treated. The treatment was performed for all patients. Seven adverse events related to the injection product or the surgical procedure were identified. After a 12-month follow-up, 12 patients were completely cured and eight were not cured, with a greater response in the first 6 months. These findings were confirmed by endoanal ultrasound, with a Cohen's kappa concordance rate of 0.89. No statistically significant differences were observed in pain measured using the visual analogue scale, faecal incontinence measured using the Wexner scoring system, and quality of life analysed by the SF-36 Health Survey. CONCLUSION The treatment was feasible, safe and with discrete satisfactory healing results. It also demonstrated an acceptable safety profile, without worsening of faecal incontinence, quality of life and pain following treatment.

Abstract
Need. The diversity of approaches proposed for the treatment of complex perianal fistulas reflects the fact that no method has yet been shown to be fully satisfactory. We believe the successful treatment of this condition is directly proportional to the amount of fibrous tissue that can be removed. Technical solution. We use a kit of small curettes, of different thicknesses and sizes, incorporating spicules that enable the physician to remove fibrous tissue from the fistula tract. The small size and varying thicknesses of the curettes enable them to mould to the curves of the fistula tract and to remove tissue by deroofing from the shallowest to the deepest layers, thus excising the entire fibrous tract. Our hospital has recently incorporated into clinical practice a new model of 3D-printed surgical steel curette, flanked by 2 lateral rings through which the suture is threaded. The central part of the curette contains radially graduated discs, the tips of which perform the debriding action, removing the fibrous tissue from the tract. Proof of concept. By using these curettes in conjunction with our standard technique (plugging the tract with platelet-rich fibrin), we have improved the success rate from 67% to 88%. Next steps. We have contacted several companies with a view to marketing this product. Conclusion. The results obtained are significantly better than those offered by the techniques in current use for the treatment of complex fistulas, without prejudice to outcomes such as anal continence and morbidity and mortality.

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
Perianal sepsis is a common condition ranging from acute abscess to chronic anal fistula. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. Surgery is the main treatment and several procedures have been developed, but the risks of recurrence and of impairment of continence still seem to be an unresolved issue. This statement reviews the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
PURPOSE To compare the clinical outcome of autologous platelet-rich growth factor (PRP) with commercial fibrin glue in the management of high cryptogenic fistulae-in-ano. METHOD The study was conducted at a single center between July 2012 and July 2015 and performed as a phase III, randomized, double-blind comparison of autologously prepared PRP versus fibrin glue for cryptoglandular anal fistulae without active sepsis. Patients were assessed with clinical and endosonographic follow-up. Patients were followed up at 1 week and then at 3, 6, and 12 postoperative months. The primary outcome measure was the fistula healing rate (complete, partial, and non-healing) with secondary outcome measures assessing fistula recurrence, continence status, quality of life, and visual analog pain scores. RESULTS Of the 56 enrolled patients, 32 were PRP-treated and 24 were fibrin-treated. The groups were well matched for fistula type with an improved overall healing rate for PRP-treated over fibrin-treated cases (71% vs. 58.3%, respectively; P = 0.608); a complete healing rate of 48.4% vs. 41.7%, respectively; and a partial healing rate of 22.6% vs. 16.7%, respectively. The median pain scores of PRP-treated patients were lower at the first visit with a greater initial pain decrease early during follow-up. Improvements in pain reduction impacted the quality of life measures (P = 0.035). All adverse events were minor and no patient experienced a negative impact on continence. CONCLUSION Treatment of complex cryptoglandular anal fistula with autologous PRP is as effective as fibrin glue with less cost and no adverse effect on continence.

Abstract
BACKGROUND Rectal advancement flap is the standard surgical treatment for complex cryptoglandular anal fistulas, while Permacol™ collagen paste is considered an innovative treatment option for anorectal fistulas. This study aimed to compare the clinical outcomes of patients with complex cryptoglandular fistulas treated by endorectal advancement flap versus Permacol™ paste. METHODS This study was a retrospective analysis of patients with complex cryptoglandular anal fistulas. Thirty-one patients were treated with the rectal advancement flap (RAF group), while 21 were treated with Permacol™ paste injection (PP group). In PP group, the approach consisted of loose seton positioning followed several weeks later by closure internal opening with a resorbable sutures associated with paste injection into the fistula track. Clinical outcomes were assessed in terms of healing rate, faecal continence and patient satisfaction. RESULTS Seton drainage was done in all patients in both groups for a median duration of 8 weeks (range 4-18 weeks) before the final surgery (p = 0.719). No patient had faecal incontinence (CGS ≥ 5) preoperatively. Five patients (16%) in the RAF group and one (5%) in the PP group experienced faecal incontinence postoperatively. The 2-year disease-free survival was 65% in the RAF group and 52% in the PP group (p = 0.659). The median satisfaction scores were 5 (range 1-10) in the RAF group and 7 (range 2-10) in the PP group (p = 0.299). CONCLUSION The RAF appeared superior to PP in terms of fistula healing, although this result was not statistically significant. On the contrary, PP has a potential advantage in terms of continence disorders. Permacol™ paste can be considered as the initial treatment option for complex cryptoglandular anal fistulas in patients with faecal continence disorders.

Abstract
BACKGROUND Permacol paste injection is a novel treatment approach for complex cryptoglandular anal fistulas. This study was performed to evaluate the long-term clinical outcomes of treatment with Permacol paste for complex cryptoglandular fistulas. METHODS Patients with primary or recurrent complex cryptoglandular anal fistulas treated with Permacol paste from 2014 to 2016 were retrospectively analyzed. RESULTS A total of 46 patients (median age, 41.3 years; 21 female) underwent Permacol paste injection; 20 patients (43%) had previously undergone failed fistula surgery. The patients had experienced anal fistula-related symptoms for a median of 10 weeks (range, 3-50 weeks). All patients had a draining seton in situ for a median of 10 weeks (range, 4-46 weeks). The median follow-up time was 24 months (range, 1-25 months). At the 1-month follow-up, 2 patients had paste extrusion and 2 had anal abscesses. The mean preoperative Continence Grading Scale score was 1.10 ± 1.40, and that at 3 months postoperatively was 1.13 ± 1.39 ( P = .322). There was a significant difference in the preoperative and the 1- and 3-month postoperative pain scores ( P < .001). At the 24-month follow-up, the healing rate was 50% (n = 23). A total of 19 patients (41%) with a recurrent fistula after failed Permacol paste injection required additional operative procedures. The satisfaction rate at the 2-year follow-up was 65%. CONCLUSION Permacol paste injection is minimally invasive and technically easy to perform. It can be considered as a viable and reasonable option for the treatment of complex cryptoglandular anal fistulas in patients with fecal continence disorders.

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
Pediatric anal fistulae commonly result from recurrent perianal abscesses, of which nearly 50 per cent develop an anal fistula. The purpose of this study was to report the results of using fibrin glue to treat anal fistula in pediatric patients. Infants and children with recurrent perianal abscesses and anal fistulae were treated with either fistulectomy or fibrin glue. Demographic and clinical characteristics and outcomes were compared between the groups. A total of 34 children were included; 27 received fistulectomy (median age eight months) and seven received fibrin glue treatment (median age 14 months). No significant differences in demographic or clinical characteristics were found between the two groups (all, P > 0.05). Median follow-up duration was significantly higher in the fibrin glue group compared with that in the fistulectomy group (five months vs one month, P = 0.003). There was one recurrence in the fistulectomy group, and no recurrences in the fibrin glue group (P = 1.0). No complications occurred in either group. Fibrin glue treatment is a simple and effective treatment alternative in the management of anal fistula in children, offering the advantage of sphincter muscle-sparing and reduced risk of fecal incontinence.

Abstract
AIM Permacol™ collagen paste (Permacol™ paste) is an acellular cross-linked porcine dermal collagen matrix suspension for use in soft-tissue repair. The use of Permacol™ paste in the filling of anorectal fistula tract is a new sphincter-preserving method for fistula repair. The MASERATI100 study was a prospective, observational clinical study with the objective to assess the efficacy of Permacol™ collagen paste for anal fistula repair in 100 patients. METHOD Patients (n = 100) with anal fistula were treated, at 10 European surgical sites, with a sphincter-preserving technique using Permacol™ paste. Fistula healing was assessed at 1, 3, 6 and 12 months post-treatment, with the primary end-point being healing at 6 months. Faecal continence and patient satisfaction were surveyed at each follow-up; adverse events (AEs) were monitored throughout the follow-up. RESULTS At 6 months postsurgery, 56.7% of patients were healed and the percentage healed was largely maintained, with 53.5% healed at 12 months. Regarding AEs, 29.0% of patients had at least one AE, and 16.0% of patients had one or more procedure-related AE. Most AEs reported were minor and similar to those commonly observed after fistula treatment, and the incidence of serious adverse events was low (4.0% of patients). Regardless of treatment outcome, 73.0% of patients were satisfied or very satisfied with the procedure. CONCLUSION Permacol™ paste is a promising sphincter-preserving treatment for anal fistulae and has minimal adverse side-effects.

Abstract
OBJECTIVE This study aims to demonstrate the effectiveness and safety of autologous fibrin gel rich in platelet growth factors for the treatment of complex perianal fistulas. MATERIAL AND METHODS Prospective epidemiological study. Patients with complex perianal fistula or perianal fistula mere alteration of continence are included. identification of both holes and the journey, curettage of it and instillation of Vivostat PRF® in the way it is done to observe excess material by OFE. The variables analyzed were: age, sex, use of prior Seton clinic prevalent type of fistula, postoperative complications, fistula closure and impaired quality of life using the SF-36 test (v2). RESULTS From January 2011 to May 2013 have involved 23 patients, 12 men and 11 women, with an average age of 49 years and a minimum follow-up of 12 months. Two dropped out. 17 patients had low transsphincteric fistulas, 2 and 2 high transsphincteric intersphincteric with impaired continence. The most common symptom is the discharge. Twelve patients had a loose seton (62%), of which nine cured. Of all the patients we have operated the success rate is 62%. No patient developed incontinence after treatment. Only two reported a worse quality of life after surgery. CONCLUSION This study demonstrates that there is a clear benefit to the use of Vivostat PRF® as a treatment for complex perianal fistulas. It is a highly reproducible technique with acceptable results and does not produce impairment of continence.

Abstract
AIM Precise information regarding the location of an anal fistula and its relationship to adjacent structures is necessary for selecting the best surgical strategy. Retrospective and cross-sectional studies were performed to determine predictive factors for recurrence of anal fistula from preoperative examination by three-dimensional endoanal ultrasound (3D-EAUS). METHOD Patients in our tertiary centre and in a private centre specialized in proctology undergoing preoperative 3D-EAUS for cryptoglandular anal fistulae between 2002 and 2012 were included. A questionnaire was sent in September 2013 to assess the patient's condition with regard to recurrence. Variables checked for association with recurrence were gender, type of centre, previous fistula surgery, secondary track formation and classification of the fistula. RESULTS There were 143 patients of whom 96 had a low fistula treated by fistulotomy, 28 a high fistula treated by fistulectomy and 19 a high fistula treated by fistulectomy combined with a mucosal advancement flap. The median duration of follow-up was 26 (2-118) months. The fistula recurred in 40 (27%) patients. Independent risk factors included the presence of secondary track formation [hazard ratio 2.4 (95% CI 1.2-51), P = 0.016] and previous fistula surgery [hazard ratio 1.2 (95% CI 1.0-4.6), P = 0.041]. Agreement between the 3D-EAUS examination and the evaluation under anaesthesia regarding the site of the internal opening, classification of the fistula and the presence of secondary tracks was 97%, 98% and 78%. CONCLUSION The identification of secondary tracks by preoperative 3D-EAUS examination was the strongest independent risk factor for recurrence. This stresses the importance of preoperative 3D-EAUS in mapping the pathological anatomy of the fistula and a thorough search for secondary track formation during surgery.

Abstract
AIM Several sphincter-preserving techniques have been described with extremely encouraging initial reports. However, more recent studies have failed to confirm the positive early results. We evaluate the adoption and success rates of advancement flap procedures (AFP), fibrin glue sealant (FGS), anal collagen plug (ACP) and ligation of intersphincteric fistula tract (LIFT) procedures based on their evolution in time for the management of anal fistula. METHOD A PubMed search from 1992 to 2015. An assessment of adoption, duration of study and success rate was undertaken. RESULTS We found 133 studies (5604 patients): AFP (40 studies, 2333 patients), FGS (31 studies, 871 patients), LIFT (19 studies, 759 patients), ACP (43 studies, 1641 patients). Success rates ranged from 0% to 100%. Study duration was significantly associated with success rates in AFP (P = 0.01) and FGS (P = 0.02) but not in LIFT or ACP. The duration of use of individual procedures since first publication was associated with success rate only in AFP (P = 0.027). There were no statistically significant differences in success rates relative to the number of the patients included in each study. CONCLUSION Success and adoption rates tend to decrease with time. Differences in patient selection, duration of follow-up, length of availability of the individual procedure and heterogeneity of treatment protocols contribute to the diverse results in the literature. Differences in success rates over time were evident, suggesting that both international trials and global best practice consensus are desirable. Further prospective randomized controlled trials with homogeneity and clear objective parameters would be needed to substantiate these findings.

Abstract
AIM Permacol collagen paste (Permacol paste) is a new option for the treatment of anorectal fistula. It functions by filling the fistula tract with an acellular crosslinked porcine dermal collagen matrix suspension. The MASERATI 100 study group was set up to evaluate the clinical outcome of Permacol paste in the treatment of anorectal fistula. This paper reports the results from the initial 30 patients enrolled in the MASERATI 100 prospective, observational clinical trial. METHOD Patients (N = 30) with anal fistula presenting to 10 European academic surgical units were treated with a sphincter-preserving technique using Permacol paste. Fistula healing was assessed at 1, 3, 6 and 12 months after treatment, with the primary end-point of fistula healing at 6 months post-surgery. Faecal continence and patient satisfaction were recorded at each follow-up visit and adverse events were monitored throughout the follow-up. RESULTS Of the 28 patients with data at 6 months post-surgery, 15 (54%) were healed, and the healing rate was maintained at 12 months. Healing after treatment with Permacol paste was similar for intersphincteric to transsphincteric fistulae and primary or recurrent fistulae. Only one patient exhibited an adverse event (perianal abscess) that was possibly related to the treatment. At the last outpatient visit, over 60% of patients were satisfied or very satisfied with the operation. CONCLUSION Permacol paste is shown to be effective in treating primary and recurrent cryptoglandular anorectal fistula with minimal unwanted side effects.

Abstract
Perianal sepsis is a common condition ranging from acute abscess to chronic fistula formation. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. The key to successful treatment is the eradication of the primary track. As surgery may lead to a disturbance of continence, several sphincter-preserving techniques have been developed. This consensus statement examines the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
Anal fistulas require surgical treatment to cure the fistula. Fistulotomy is the treatment of choice because of its high success rate, but it also carries a risk of postoperative incontinence. Different methods have been proposed to overcome the need for dividing part or all of the sphincter, so-called "sphincter saving techniques" (SST), such as flap advancement, intrafistular injection of glue, or the insertion of a bio-prosthesis (collagen plug). However, the success rate of SSTs is lower than that of fistulotomy. Ligation of the Intersphincteric Fistula Tract (LIFT) is one of the most recent SSTs. It aims to ligate and transect the fistula by an approach through the intersphincteric space. The methodological quality of most published studies has been only average, but several studies have reported attractive success rates of 70 to 95% without postoperative incontinence. Other techniques such as endo-anal clip or injection of autologous stem cells are still anecdotal.

Abstract
AIM: To compare healing rates between intersphincteric fistula tract (LIFT) and LIFT plus partial fistulectomy procedures.
METHODS: A study of complex fistula-in-ano patients was carried out from 1st March 2010 to 31th January 2012. All operations were done by colorectal surgeons at a referral center in a Ministry of Public Health hospital. Data collected included patients’ demographic details, fistula type determined by endorectal-ultrasonography, preoperative and postoperative continence status, previous operations, time between diagnosis of fistula-in-ano and operation, type of surgery, healing rates, recurrence rates, and types of failure examined by endorectal-ultrasosnography, re-operation in recurrence or failure cases, and complications.
RESULTS: The study involved 41 patients whose average age was 40.78 ± 11.84 years (range: 21-71 years). The major fistula type was high-transsphincteric type fistula. The median follow-up period was 24 wk. The overall success rate was 83%: in the LIFT (Ligation intersphincteric fistula tract) group the success rate was 81% and in the LIFT plus (LIFT with partial coreout fistulectomy) group it was 85% (P = 0.529). The median wound-healing time was 4 wk in both groups (P = 0.262). The median time to recurrence was 12 wk. Neither group had incontinence (Wexner incontinence score-0) and the difference in healing rates between the two groups was not statistically significant.
CONCLUSION: There was no difference in results between LIFT and LIFT plus operations. The LIFT procedure is a good option for maintaining continence in management of fistula-in-ano.

Abstract
New technical approaches involving biologically derived products have been applied in the treatment for anal fistulas in order to avoid the risk of fecal incontinence. The aim of this review was to evaluate the scientific evidence present in the literature regarding these techniques. Trials comparing surgery (fistulotomy, advancement mucosal flap closure and placement of seton) versus fibrin glue, fistula plug or acellular dermal matrix were considered. In fibrin glue versus traditional surgical treatment the healing rate was higher in the surgery group, and the recurrence rate was lower in the traditional surgery group, but these results were not statistically relevant. In acellular dermal matrix (ADM) versus traditional surgical treatment the recurrence rate of fistulas was significantly lower in the ADM group, but non-significant differences were recorded in incontinence and anal deformity. Our review shows that there are no significant advantages of the new techniques involving biologically derived products. Further randomized controlled trials are needed.

Abstract
BACKGROUND Complex anal fistulas remain a challenge for the colorectal surgeon. The anal fistula plug has been developed as a simple treatment for fistula-in-ano. We present and evaluate our experience with the Surgisis anal fistula plug from two centres. METHODS Data were prospectively collected and analysed from consecutive patients undergoing insertion of a fistula plug between January 2007 and October 2009. Fistula plugs were inserted according to a standard protocol. Data collected included patient demographics, fistula characteristics and postoperative outcome. RESULTS Forty-four patients underwent insertion of 62 plugs (27 males, mean age 45.6 years), 25 of whom had prior fistula surgery. Mean follow-up was 10.5 months Twenty-two patients (50%) had successful healing following the insertion of plug with an overall success rate of 23 out of 62 plugs inserted (35%). Nineteen out of 29 patients healed following first-time plug placement, whereas repeated plug placement was successful in 3 out of 15 patients (20%; p = 0.0097). There was a statistically significant difference in the healing rate between patients who had one or less operations prior to plug insertion (i.e. simple fistulas) compared with patients who needed multiple operations (18 out of 24 patients vs. 4 out of 20 patients; p = 0.0007). CONCLUSIONS Success of treatment with the Surgisis anal fistula plug relies on the eradication of sepsis prior to plug placement. Plugs inserted into simple tracts have a higher success rate, and recurrent insertion of plugs following previous plug failure is less likely to be successful. We suggest the fistula plug should remain a first-line treatment for primary surgery and simple tracts.
