Seton in Treating ComplexAnorectal Fistula-Our Experience

Background : Complex anorectal fistula may be endowed by the level at which the primary tract crosses the sphincters, the presence of secondary extensions or the difficulties faced in the treatment. Existing different treatment modalities like local advancement flap, LIFT procedure, fistulotomy and use of seton. Surgeons are afraid of incontinence in treating complex anorectal fistula. The aim of treatment of anal fistula is to cure the disease avoiding faecal incontinence. Among different procedures, Seton, a thread of foreign material, passed through the fistulous track and encircling sphincter mass thereby severing the muscle gradually without allowing it to spring apart and replacing the cut by the line of fibrosis thus avoiding incontinence, is an acceptable method practiced world wide. The purpose of the study is to evaluate and share our experience with others about the result of using seton in the treatment of complex anal fistula in our setting.
 Method: Between January 2003 and December 2008, I have taken the 1st 100 patients underwent surgery for complex anal fistula in Colorectal Surgery Unit of Bangabandhu Sheikh Mujib Medial University, Dhaka. It involved initial identification and partial laying open of the fistulous tract. A tight seton is placed around the external sphincter and is not removed until the internal orifice has migrated towards the perianal skin.
 Results: Out of 100 patients with mean age 43 years (range 19-65 years) 6 female and rest male underwent the procedure of seton. The median follow-up was 28.6 (24-36) months. The mean time of wound healing was 9.5 weeks (range 6-15). Recurrence occurred in two patient (2%). Continence disorders of flatus and loose stool were noted in 14 patients (14%). The duration with the seton in place was 56 days (range 20-190).
 Conclusion: The technique shows excellent results in the treatment of complex anal fistulous with preservation of faecal continence.

Photodynamic Therapy for the Treatment of Complex Anal Fistula.

To validate and analyze the results of intralesional photodynamic therapy in the treatment of complex anal fistula. This prospective multicentric observational study enrolled patients treated for complex anal fistula who underwent intralesional photodynamic therapy (i-PDT). The included patients were treated from January 2016 to December 2018 with a minimum follow-up of 1 year to evaluate recurrence, continence and postoperative morbidity. Intralesional 5-aminolevulinic acid (ALA) gel (2%) was injected directly into the fistula. The internal and external orifices were closed. After an incubation period of 2 hours, the fistula was irradiated using an optical fiber connected to a red laser (Multidiode 630 PDT) operating at 1 W/cm for 3 minutes (180 J). In total, 49 patients were included (61.2% male). The mean age was 48 years, and the mean duration of fistula was 13 months. Of the fistulas included, 75.5% were medium transphincteric, and 24.5% were high transphincteric. The median fistula length was 4 ± 1,14 cm (range: 3-5). A total of 41 patients (83.7%) had a previous history of fistula surgery. Preoperatively, some degree of anal incontinence was found in 5 patients (10.2%). No center reported any other procedure-related complications intraoperatively. Phototoxicity was found in one patient. In the first 48 hours after the procedure, fever was reported in 2 patients (4%). At the end of follow-up, total healing was observed in 32/49 patients (65.3%). No patient reported new incontinence postoperatively. i-PDT could be considered a good choice in patients with complex anal fistulas to avoid surgery and its complications. Lasers Surg.

Drainage Seton Versus External Anal Sphincter-Sparing Seton After Rerouting of the Fistula Tract in the Treatment of Complex Anal Fistula: A Randomized Controlled Trial.

Complex anal fistula is one of the challenging anorectal conditions. Several treatments have been proposed for complex anal fistula, yet none proved to be ideal. This randomized trial aimed to assess the efficacy of external anal sphincter-sparing seton in comparison with the conventional drainage seton in the treatment of complex anal fistula. This was a prospective, randomized, single-blind controlled study. The study was conducted at the Colorectal Surgery Unit of Mansoura University Hospitals. Adult patients of both sexes with complex anal fistula were recruited and evaluated with MRI before surgery. Patients were randomly divided into 2 groups; group 1 was treated with conventional drainage seton and group 2 was treated with external anal sphincter-sparing seton using a rerouting technique. The duration of healing, incidence of recurrence or persistence, postoperative pain, and complications including fecal incontinence were measured. Sixty patients (56 men) with a mean age of 43 years were included. Mean operation time in group 1 was significantly shorter than group 2 (29.8 ± 4.3 vs 43.8 ± 4.5 min; p < 0.0001). The mean pain score at 24 hours in group 1 was 8.1 ± 1.6 versus 5.3 ± 1.3 in group 2 (p < 0.0001). Five patients (17%) in group 1 experienced complications versus 2 (7%) in group 2. All of the patients in group 1 required a second-stage fistulotomy versus 2 patients (7%) in group 2 (p < 0.0001). Time to complete healing in group 1 was significantly (p < 0.0001) longer than group 2 (103 ± 47 vs 46 ± 18 d). Four patients (13%) in group 1 and 1 patient (3%) in group 2 experienced persistence or recurrence of anal fistula (p = 0.35). This was a single-center study with relatively small numbers in each group. Patients treated with external anal sphincter-sparing seton after rerouting of the fistula tract achieved quicker healing and less postoperative pain than those with conventional drainage seton. Postoperative complication and recurrence rates were comparable in both groups.

The clinical efficacy of stem cell therapy for complex perianal fistulas: a meta-analysis.

Treatment of complex anal fistulas remains difficult. However, treatment with stem cells has had an encouraging success rate when applied to complex perianal fistulas. We systematically reviewed the current evidence through meta-analysis. We performed an electronic literature search on PubMed, Embase, and the Cochrane Library and identified studies (published between January 1946 and August 2017) that used stem cells to treat patients with complex perianal fistula. Each paper was evaluated for treatment success rate, target patients, types of stem cells used, number of cells used, and criteria for complete healing. Potential publication bias was assessed via visual inspection of a funnel plot and Orwin's fail-safe N. Out of 171 papers, 16 were included in the meta-analysis. The overall healing rate of stem cell injection therapy for patients with complex perianal fistulas was 62.8% (95% CI 53.5-71.2, I2 = 54.05%), whereas those for patients with Crohn's perianal fistulas alone and complex anal fistulas not associated with Crohn's disease were 64.1% and 61.5% (p = 0.840), respectively. Healing rates for autologous and allogenic stem cell treatment were 69.4% and 50.7% (p = 0.020), respectively. Four comparative studies out of 16 studies were analyzed separately. Stem cell therapy increased the healing rate compared to the control groups (OR 0.379, 95% CI 0.152-0.947). Stem cell therapy is a good treatment option for complex perianal fistulas, which cannot be healed by conventional operative procedures. However, further research for additional supportive evidence, such as a large-scale randomized controlled trial, is required.

Outcome of Modified Park's Technique for Treatment of Complex Anal Fistula

BackgroundTreatment of complex anal fistula (CAF) can be associated with high rates of recurrence and fecal incontinence (FI). Park suggested drainage of the affected intersphincteric anal gland for treatment of cryptoglandular anal fistula; however, recurrence after this technique was high. We modified the original Park's technique by extending the internal sphincterotomy to ensure adequate drainage of the intersphincteric space. The aim of this study was to evaluate the incidence of recurrence and FI after modified Park's technique in treatment of CAF. MethodsAdult patients of both genders with CAF were evaluated before undergoing modified Park's technique with Wexner continence score, clinical examination, and endoanal ultrasonography or MRI. Postoperatively, patients were examined every 2 wk until complete wound healing. The continence state was evaluated with Wexner continence score, and quality of life was assessed before surgery and at 6 mo postoperatively by Short Form–36 questionnaire. ResultsThirty-two patients (27 male) of a mean age of 38 y were included. Median follow-up was 12 mo. Two patients (6.25%) experienced recurrence and 5 (15.6%) developed complications. One patient (3.1%) developed new-onset FI postoperatively. Twenty-eight (87.5%) patients were completely satisfied with the procedure. Quality of life showed significant improvement at 6 mo postoperatively. ConclusionsThe modified Park's technique is a promising procedure for the treatment of CAF with low recurrence and FI rates, and improved quality of life.

Clinical comparative study of two kinds of extra-dissection and loose seton operation in the treatment of complex anal fistula complicated with abscess

Objective To compare the clinical efficacy and safety of second-stage and one-stage extra-dissection and loose seton operation in the treatment of complex anal fistula complicated with abscess. Methods From May 2015 to December 2016, 100 patients with complex anal fistula complicated with abscess were chosen in the First People's Hospital of Wuyi County.The patients were randomly divided into two groups, with 50 patients in each group.The control group received second-stage extra-dissection and loose seton operation, and the observation group received one-stage extra-dissection and loose seton operation.The clinical effects, operation time, wound healing time, hospital stay and the incidence of complications after operation of the two groups were compared. Results The total effective rates of the control group and the observation group were 94.00%, 96.00%, respectively, there was no statistically significant difference between the two groups(χ2=8.78, P>0.05). The operation time, wound healing time and hospital stay of the observation group were shorter than those of the control group, and the differences were statistically significant(t=3.72, 2.96, 3.40, all P 0.05). Conclusion Second-stage and one-stage extra-dissection and loose seton operation in the treatment of complex anal fistula complicated with abscess has the same clinical effects and safety; but one-stage extra-dissection and loose seton operation can efficiently shorten the operation time and speed up the postoperative rehabilitation.

Autologous bone marrow derived stem cells in the treatment of complex anal fistula

Background: Treatment of anal fistula shows a great conflict between preservation of continence and eradication of sepsis. Stem cells extracted from bone marrow are able to home to inflamed tissues and repair injured ones. The aim of this study is to present the early results of injection of stem cells to tracts of complex recurrent fistulae. The primary outcome of the study is the healing of the complex fistula secondary outcomes include safety profile of the procedure.Methods: 15 patients having complex anal fistulae. To prepare stem cells, bone marrow aspiration was performed under complete aseptic conditions. After several steps for isolation, viability testing and preparation, stem cells were suspended in sterile saline for injection in the patients. The internal opening was identified and closed then curettage of the tract with injection of cell suspension simultaneous with fibrin glue followed by injection of stem cell suspension around the tract and external opening finally it was closed. The first evaluation was performed after 8 weeks, a final evaluation after one year.Results: Categorized into three groups (a) complete healing 8 patients (53.3%). (b) Incomplete healing 4 patients (26.7%) (c) Recurrence 3 patients (20%) No incontinence, abnormal tissue growth or major adverse effects were reported.Conclusions: Use of autologous bone marrow-derived stem cells in anal fistula treatment is a recent modality with variable rates of success. Despite the rate of failure or incomplete healing but it still provides a solution to avoid continence impairment. It needs better evaluation with larger sample size, with long-term follow up. literatures.

Complex anal fistulae management by combined technique approach: an experience

Background: The aim of this study is to evaluate our experience in the management of complex anal fistulae by combined technique approach. Ideal surgical treatment for complex anal fistula should aim to eradicate the source of infection and promote healing of the tract, while preserving the sphincters and the mechanism of anal continence. Even with the evolving newer techniques complex anal fistulae have higher rates of recurrence and functional disability as anal incontinence. The requirement of multiple surgeries for recurrence and the newer techniques like anal fistula plug are expensive and will become a burden for patients living in developing countries like ours. Thus, apart from Ligation of Intersphincteric fistula tract, the use of cutting seton is the main surgical method practiced here. This article focuses on the approach to the complex anal fistula management through evidence-based treatment strategies.Methods: Author conducted a prospective study of 35 complex anal fistulae patients undergoing combined technique approach with cutting Seton, Ligation of Intersphincteric Fistula tract and fistulotomy. Results: All patients recovered well with no complications in postoperative period. After 2 years of follow up patients are recurrence free and only 2 patients had partial incontinence with improving trend.Conclusions: The use of cutting Seton in high anal fistula is an effective technique. LIFT technique is good for Transphincteric tracts without previous scarring; it can be easily learned and applied. We can conclude that combined technique was an effective procedure and valid alternative for complex anal fistula management.

Outcome of hybrid seton placement for the treatment of high complex anal fistulas with and without tube drainage: A prospective comparative study

The aim of this study was to investigate the efficacy of treatment for complex anal fistula with cutting hybrid seton combined with tube drainage. A total of 66 consecutive patients with complex anorectal fistulae were divided into two groups: experimental group (group A with 36 patients) underwent cutting hybrid seton placement plus tube drainage and control group (group B with 30 patients) underwent same procedure without tube drainage. Comparison of clinical outcomes between two groups was conducted. The success rate, time for healing of the wound, postoperative pain, and recurrence rate were analyzed. No patient was lost to follow-up. Some major clinical outcomes presented significant differences. Experimental group was superior than the control group in the aspects of success rate, time for healing of the wound, postoperative pain score, and recurrence rate. We can conclude that cutting hybrid seton placement with tube drainage was an effective procedure and valid alternative for complex anorectal fistula with a favorable result on higher healing rate, less postoperative pain, and few impact on the function of sphincter.

Video-Assisted Anal Fistula Treatment (VAAFT) for Complex Anal Fistula: A Preliminary Evaluation in China.

BackgroundAlthough many attempts have been made to advance the treatment of complex anal fistula, it continues to be a difficult surgical problem. This study aimed to describe the novel technique of video-assisted anal fistula treatment (VAAFT) and our preliminary experiences using VAAFT with patients with complex anal fistula.Material/MethodsFrom May 2015 to May 2016, 52 patients with complex anal fistula were treated with VAAFT at Yangpu Hospital of Tongji University School of Medicine, and the clinical data of these patients were reviewed.ResultsVAAFT was performed successfully in all 52 patients. The median operation time was 55 minutes. Internal openings were identified in all cases. 50 cases were closed with sutures, and 2 were closed with staplers. Complications included perianal sepsis in 3 cases and bleeding in another 3 cases. Complete healing without recurrence was achieved in 44 patients (84.6%) after 9 months of follow-up. No fecal incontinence was observed. Furthermore, a significant improvement in Gastrointestinal Quality of Life Index (GIQLI) score was observed from preoperative baseline (mean, 85.5) to 3-month follow-up (mean, 105.4; p<0.001), and this increase was maintained at 9-months follow-up (mean, 109.6; p<0.001).ConclusionsVAAFT is a safe and minimally invasive technique for treating complex anal fistula with preservation of anal sphincter function.

FILAC – Fistula – Tract Laser Closure: a sphincter-preserving procedure for the treatment of complex anal fistulas

Several surgical options are described for the treatment of anorectal fistulas, particularly in complex cases where recurrence rates and the possibility of postoperative incontinence are still high. The aim of this study is to describe the use of FILAC technique (Fistula – Tract Laser Closure) minimally invasive and preservation sphincter technique. FILAC has been described in the literature as an option in the management of anorectal fistula.

Advancement Flap for Treatment of Complex Cryptoglandular Anal Fistula: Prediction of Therapy Success or Failure Using Anamnestic and Clinical Parameters.

Multiple new procedures for treatment of complex anal fistula have been described in the past decades, but an ideal single technique has yet not been identified. Factors that predict the outcome are required to identify the best procedure for each individual patient. The aim of this study was to find those predictors for advancement flap at midterm follow-up. From 2012 to 2015 in a tertiary university clinic, all patients who underwent advancement flap for treatment of complex cryptoglandular fistula were prospectively enrolled. Pre- and postoperatively standardized anamnestic and clinical examinations were performed. Predictive factors for therapy failure were identified using univariate and multivariate analysis. Out of 65 patients, 61 (93%) completed all examinations and were included in the study. Therapy failure after a mean follow-up period of 25months occurred in total n=11 patients (18%). There was no significant disturbance of continence among the entire study cohort as shown by the incontinence score (preop 0.34±0.91 pts., postop 0.37±0.97 pts.; p=0.59). Univariate analysis for risk factors for therapy failure revealed age (p=0.004), history of surgical abscess drainage (p=0.04), BMI (p=0.002), suprasphincteric fistula (p=0.019) and horseshoe abscess (p=0.036) as independent parameters for therapy failure. During multivariate analysis, only history of surgical abscess drainage (OR=8.09, p=0.048, 95% CI 0.98-64.96), suprasphincteric fistula (OR=6.83, p=0.032, 95% CI 1.17-6.83) and BMI (OR=1.23, p=0.017, 95% CI 1.03-1.46) were independent parameters for therapy failure. Advancement flap for treatment of complex fistula is effective and has low risk of disturbed continence. BMI, suprasphincteric fistula and history of surgical abscess drainage are predictors for therapy failure.

Pay attention to the imaging diagnosis of complex anal fistula

The diagnosis and treatment of complex anal fistula has been a significant challenge. Unwise incision and excessive exploration will lead to the secondary branch, sinus and perforation. A simple fistula may become a surgical problem and result in disastrous consequences. Preoperative accurate diagnosis of anal fistula, including in the internal opening, primary track and location of the fistula, extensions and abscess, is important for anal fistula treatment. In the diagnosis of anal fistula, imaging examination, especially MRI plays a crucial role. Localization and demarcation of anal fistula and the relationship with sphincter are important. MRI has been an indispensable confirmatory imaging examination.

Treatment of Fistula-In-Ano with Fistula Plug - a Review Under Special Consideration of the Technique.

In a recent Cochrane review, the authors concluded that there is an urgent need for well-powered, well-conducted randomized controlled trials comparing various modes of treatment of fistula-in-ano. Ten randomized controlled trials were available for analyses: There were no significant differences in recurrence rates or incontinence rates in any of the studied comparisons. The following article reviews the studies available for treatment of fistula-in-ano with a fistula plug with special attention paid to the technique. PubMed, Medline, Embase, and the Cochrane medical database were searched up to July 2015. Sixty-four articles were relevant for this review. Healing rates of 50-60% can be expected for treatment of complex anal fistula with a fistula plug, with a plug-extrusion rate of 10-20%. Such results can be achieved not only with plugs made of porcine intestinal submucosa but also those made of other biological or synthetic bioabsorbable mesh materials. Important technical steps are firm suturing of the head of the plug in the primary opening and wide drainage of the secondary opening. Treatment of a complex fistula-in-ano with a fistula plug is an option with a success rate of 50-60% with low complication rate. Further improvements in technique and better studies are needed.

Fistulotomy or fistulectomy and primary sphincteroplasty for anal fistula (FIPS): a systematic review.

There is still no clear consensus about surgical treatment of anal fistulas. Fistulotomy or fistulectomy and primary sphincter reconstruction is still regarded with skepticism. The aim of this systematic review was to evaluate the evidence in the literature supporting the use of this technique in the treatment of complex anal fistulas. MEDLINE, EMBASE and Cochrane Library databases were searched for the period between 1985 and 2015. The studies selected were peer-reviewed articles, with no limitations concerning the study cohort size, length of the follow-up or language. Technical notes, commentaries, letters and meeting abstracts were excluded. The major endpoints were the technique adopted, clinical efficacy, changes at anorectal manometry and assessment of quality of life after the procedure. Fourteen reports (666 patients) satisfied the inclusion criteria. The quality of the studies was low. Some differences about the surgical technique emerged; however, after a weighted average duration of follow-up of 28.9months, the overall success rate was 93.2%, with a low morbidity rate. The overall postoperative worsening continence rate was 12.4% (mainly post-defecation soiling). In almost all cases, the anorectal manometry parameters remained unchanged. The quality of life, when evaluated, improved significantly. Fistulotomy or fistulectomy and primary sphincteroplasty could be a therapeutic option for complex anal fistula. Success rates were very high and the risk of postoperative fecal incontinence was lower than after simple fistulotomy. Well-designed trials are needed to support the inclusion of this technique in a treatment algorithm for the management of complex anal fistulas.

Clinical Role of Modified Seton Procedure and Coring Out for Treatment of Complex Anal Fistulas Associated With Hidradenitis Suppurativa.

A variety of techniques have been described to treat complex anal fistulas. When complex anal fistulas are associated with hidradenitis suppurativa, the treatment has to be appropriately tailored for the severity and distribution of the disease so as to remove the external fistula tract to prevent recurrence while ensuring fecal continence. Between 2007 and 2011, a total of 10 males (ranging in age from 32 to 54 years) complained of recurrent purulent discharge in the buttocks and thigh regions. The discharge had started about 12 to 18 months prior, and had increased progressively resulting in complex anal fistulas and hidradenitis suppurativa in the buttocks. They underwent surgical operation according to a modified seton procedure for complex anal fistulas and coring out for hidradenitis suppurativa. They were discharged from the hospital in 4 to 5 days, while the seton dropped spontaneously about 6 to 8 months after surgery. They have been well without any morbidities or recurrence. The present paper demonstrates that cases of complex anal fistulas associated with hidradenitis suppurativa can be successfully treated with a modified seton procedure and coring out of hidradenitis suppurativa.

Combined partial fistulectomy and electro-cauterization of the intersphincteric tract as a sphincter-sparing treatment of complex anal fistula: clinical and functional outcome.

The aim of this study was to report a simple, effective and safe procedure, associated with minimal risk of incontinence and recurrence, for treating complex anal fistulas. This was a prospective study of 53 consecutive patients with complex anal fistulas. The technique used included excision of the distal part of the fistula tract down to the external anal sphincter and electro-cauterization of the intersphincteric part of the tract with simple closure of the internal opening. Data collected included patient characteristics, fistula type determined by magnetic resonance imaging, pre- and postoperative continence status evaluated using the Wexner incontinence score (0-10), previous operations, hospital stay, healing time, recurrence rate and complications. The patients had a mean age of 41.37 ± 7.82 years; the most frequent fistula type was the high transsphincteric fistula; the mean follow-up period was 19 months with a success rate of 92.5 %; the mean wound healing time was 3.6 weeks; the incontinence scores were the same as before the procedure. The recurrence rate was 7.5 %. Partial fistulectomy combined with electrocauterization of the intersphincteric fistula tract is a simple, and effective procedure for the treatment of complex anal fistulas.

Anal fistula plug: a prospective evaluation of success, continence and quality of life in the treatment of complex fistulae

Curing complex anal fistula without compromising continence can be extremely challenging. This study investigated the healing rate, continence and quality of life of patients after treatment of complex anal fistula of cryptoglandular origin with a bioprosthetic plug. Consecutive patients were prospectively followed in four referral centres. Following seton conditioning, a bioprosthetic plug was inserted into the fistula and sutured to the anal sphincter. Clinical evaluation was performed at 10 days, 6 weeks and 6 months after surgery, and was completed by telephone interviews. Anal continence and quality of life were evaluated using the Fecal Incontinence Score Index and the Short Form-36 Health Survey, version 2 (SF-36 v2) questionnaire. Forty-six patients presenting with a complex anal fistula and a median of three previous fistula surgeries were included. The 6-month recurrence rate was 30.7% (95% CI: 15.9-42.8%), increasing to 48.0% (95% CI: 30.6-61.1%) after 2 years. Follow up was continued for a median of 68.1 months, and 26 (56.5%) recurrences were identified. Anal continence improved from a median of 19 points to 12 points at 6 months of follow up (P = 0.008). Quality of life markedly improved in all scales. The physical summary score increased from 47.2 to 56.2 (P < 0.001), and the mental summary score increased from 48.5 to 55.3 (P = 0.013). The bioprosthetic fistula plug demonstrated a healing rate close to 50% in complex cryptoglandular fistula. Also, it markedly improved anal continence and quality of life. These data support the use of a bioprosthetic plug as first-line therapy for complex fistula instead of more aggressive and potentially debilitating surgical options.

Modified plug repair with limited sphincter sparing fistulectomy in the treatment of complex anal fistulas.

Purpose: New technical approaches involving biologically derived products have been used to treat complex anal fistulas in order to avoid the risk of fecal incontinence. The least invasive methods involve filling out the fistula tract with fibrin glue or introduction of an anal fistula plug into the fistula canal following thorough curettage. A review shows that the new techniques involving biologically derived products do not confer any significant advantages. Therefore, the question inevitably arises as to whether the combination of a partial or limited fistulectomy, i.e., of the extrasphincteric portion of the fistula, and preservation of the sphincter muscle by repairing the section of the complex anal fistula running through the sphincter muscle and filling it with a fistula plug produces better results.Methods: A modified plug technique was used, in which the extrasphincteric portion of the complex anal fistula was removed by means of a limited fistulectomy and the remaining section of the fistula in the sphincter muscle was repaired using the fistula plug with fixing button.Results: Of the 52 patients with a complex anal fistula, who had undergone surgery using a modified plug repair with limited fistulectomy of the extrasphincteric part of the fistula and use of the fistula plug with fixing button, there are from 40 patients (follow-up rate: 77%) some kind of follow-up informations, after a mean of 19.32 ± 6.9 months. Thirty-two were men and eight were women, with a mean age of 52.97 ± 12.22 years. Surgery was conducted to treat 36 transsphincteric, 1 intersphincteric, and 3 rectovaginal fistulas. In 36 of 40 patients (90%), the complex anal fistulas or rectovaginal fistulas were completely healed without any sign of recurrence. None of these patients complained about continence problems.Conclusion: A modification of the plug repair of complex anal fistulas with limited fistulectomy of the extrasphincteric part of the fistula and use of the plug with fixing button seems to increase the healing rate in comparison to the standard plug technique.
