Fistulectomy and primary sphincteroplasty in complex anal fistula treatment: a hospital-based long-term follow-up study. Tech Coloproctol 2023; 27:145-152. [PMID: 36371771 DOI: 10.1007/s10151-022-02722-w] [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: 03/27/2022] [Accepted: 10/19/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND Currently, there is no agreement on the best treatment for complex anal fistulas with the least recurrence and lowest complication rate. The aim of this study was to evaluate the long-term recurrence and incontinence after fistulectomy and primary sphincteroplasty (FIPS) in a group of patients with complex perianal fistula. METHODS This prospective observational study was done at the colorectal ward of Taleghani Hospital of Tehran from January 2010 to December 2020. Patients with anal fistula who underwent FIPS were studied. After surgery, patients were evaluated regularly by a colorectal surgeon for fistula recurrence and incontinence. Recurrence was described as a new fistula tract formation after the initial cure and failure of healing in the operation site or any purulent discharge from the fistula tract and openings. In addition, the patient's continence was assessed based on the Wexner score. RESULTS There were 335 patients (66 men and 269 women, mean age 42.74 ± 12.44 years), 191 of them with low fistula and 144 with high fistula. Thirteen patients (3.90%) experienced recurrence (all had a low fistula). Thirty-nine patients (11.64%), 19 patients with high and 20 patients with low fistula, had a Wexner score ≥ 3 during the follow-up. Fifteen patients were lost to follow-up. Male patients (OR = 2.67, 95% CI 0.84, 8.45, p = 0.094, adjusted OR = 4.41, 95% CI 1.05, 18.48, p = 0.042), patients with low fistula (p = 0.001), and recurrent cases had a significantly higher rate of recurrence (OR = 10.38, 95% CI 3.24-33.20 p ≤ 0.001, adjusted OR = 23.36, 95% CI 4.35-125.39, p ≤ 0.001). A significant correlation between body mass index > 35 kg/m2 and incontinence was found (OR = 4.40, 95% CI 1.35, 14.33, p = 0.014). CONCLUSIONS In the present study, an acceptable healing rate and a low percentage of complications following FIPS were seen in patients with complex anal fistula. Randomized clinical trials with appropriate follow-up duration and sample size comparing different surgical methods in these patients are needed to confirm these results.

Abstract
AIM To evaluate the long-term success rate of treatment with the Surgisis® (Biodesign® ) anal fistula plug for complex anal fistulas, assess fistula plug failure over time and compare success rates for fistula plug between a group of patients with cryptoglandular fistula and another group with Crohn's fistula. METHOD This is a single-centre study of consecutive patients treated with the Surgisis® (Biodesign® ) anal fistula plug between May 2006 and October 2009. All patients had complex anal fistulas in need of surgical treatment. The patients were assessed preoperatively by physical examination and three-dimensional (3D) endoanal ultrasound, and treated with a loose seton. Postoperative assessment by clinical examination and 3D endoanal ultrasound was performed at 2 weeks, 3 months and 6-12 months. Long-term follow-up was carried out in 2017 using a questionnaire, and clinical examination combined with 3D endoanal ultrasound was performed if the questionnaire indicated any signs of fistula recurrence. RESULTS A total of 95 patients were included; 30 had quiescent Crohn's disease. Overall, 151 plug procedures were performed. Long-term follow-up was undertaken in 90 (95%) patients; the results showed that after a median period of 110 months, the overall healing rate after one to five plug procedures was 38%. No statistically significant difference in success rate was found between the cryptoglandular fistula group and the Crohn's fistula group (P = 0.37). No further healing was observed after the use of three plugs. CONCLUSION Considering its low morbidity in a complex disease with high recurrence rates over time, the anal fistula plug may still be considered as one of the first-line treatments for patients with complex anal fistulas.

Langenbecks Arch Surg 2020; 406:855-861. [PMID: 33174168 DOI: 10.1007/s00423-020-02024-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 11/03/2020] [Indexed: 12/12/2022]
Abstract
PURPOSE The aim of this study was to evaluate the anal function in patients with trans-sphincteric anal fistulas who underwent an anal fistula plug procedure, and analyze risk factors that might affect post-operative anal function. METHODS This was an observational, retrospective study of patients diagnosed with trans-sphincteric anal fistulas and initially underwent anal fistula plug procedures between August 2008 and September 2012 at our institute. The analysis includes clinical characteristics, anal fistula healing, and the Wexner score for pre- and post-operative anal function (0 = no incontinence to 20 = complete incontinence). RESULTS A total of 123 patients who had an adequate follow-up in the end were included. The median duration of follow-up was 8 years (range 72-121 months). The overall healing rate was 56% (69/123), and 33 (26.8%) patients had decreased anal function after surgery. The post-operative Wexner score on anal function was significantly higher than that before the operation (p < 0.001), as well as scores of gas, liquid stool, solid stool incontinence, and alteration in lifestyle (p < 0.05). Based on multiple logistic regression analysis, a high body mass index (p < 0.001) and long distance between the external opening and anal verge (p = 0.003) were significantly associated with a decline in post-operative anal function. CONCLUSIONS As a sphincter-preserving technique for the treatment of anal fistulas, the anal fistula plug procedure might impair the anal function. Especially for patients with obesity or long distance between the external opening of anal fistula and anal verge, the reduced anal function is more likely to occur after treatment with anal fistula plug therapy.

A comparative study on the effectiveness of rectal advancement flap and seton placement surgeries in patients with anal fistula on the rate of recurrence, incontinence and infection. J Family Med Prim Care 2019; 8:3591-3594. [PMID: 31803658 PMCID: PMC6881962 DOI: 10.4103/jfmpc.jfmpc_760_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 09/12/2019] [Accepted: 10/20/2019] [Indexed: 12/18/2022] Open
Abstract
Introduction: Due to the high prevalence of anal fistulas and the recurrence of the disease following surgery, different methods have been suggested for appropriate treatment of this disease. In this study, the effects of rectal advancement flap surgery and seton placement on the recurrence rate, incontinence and wound infection were compared. Methods: In this interventional, prospective and quasi-experimental study, 45 patients with anal fistulas including 28 males and 17 females were studied for 2 years (2015-2017). Patients were divided into two groups and mucosal advancement flap and seton placement techniques were used for each of them. Descriptive analysis of data was performed by SPSS software. Results: 24 patients (54%) had seton placement surgery and 21 patients (46%) underwent rectal advancement flap surgery. Recurrence was significantly higher in patients who underwent seton placement surgery than the group that underwent rectal advancement flap surgery. Twelve patients (57%) who underwent rectal advancement flap surgery showed improvement in sphincter tone while 11 patients (45%) showed improvements with seton placement. Conclusion: The overall results of this study showed that rectal advancement flap surgery reduces recurrence and wound infection more significantly than seton placement in patients with anal fistula.

Abstract
Hemorrhoids, anal fissures, and fistulas are common benign anorectal diseases that have a significant impact on patients’ lives. They are primarily encountered by primary care providers, including internists, gastroenterologists, pediatricians, gynecologists, and emergency care providers. Most complex anorectal disease cases are referred to colorectal surgeons. Knowledge of these disease processes is essential for proper treatment and follow up. Hemorrhoids and fissures frequently benefit from non-operative treatment; they may, however, require surgical procedures. The treatment of anorectal abscess and fistulas is mainly surgical. The aim of this review is to examine the etiology, diagnosis, medical, and surgical treatment for these benign anorectal diseases.

Abstract
BACKGROUND Clinical trials have reported that flap repair (FR) can treat anal fistula (AF) effectively. However, no study systematically investigated its efficacy and safety for patients with AF. This study will systematically assess its efficacy and safety of AF. METHODS We will retrieve MEDLINE, EMBASE, Cochrane Library, Elsevier, Springer, Web of Science, Scopus, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Information, and Wanfang Data from their inceptions to May 1, 2019 without any language limitations. The primary outcome is fistula cure rate. The secondary outcomes consist of fistula recurrence rate, fecal continence, quality of life, and complications. RevMan 5.3 software will be used for methodological quality assessment, data synthesis, subgroup analysis and sensitivity analysis. RESULTS The results of this study will summarize a high-quality synthesis of current evidence for the treatment of FR for patients with AF. CONCLUSION The findings of this proposed study will provide evidence for judging whether FR is an effective and safety intervention for AF or not.PROSPERO registration number: PROSPERO CRD42019135507.

Abstract
AIM The aim was to compare the effectiveness of the anal fistula plug (AFP) with the rectal advancement flap (RAF) for complex cryptoglandular anal fistulas. METHODS We conducted a literature search to identify relevant available articles published without language restriction from Embase and PubMed databases and the Cochrane Library. Studies comparing outcomes with the AFP vs RAF for complex cryptoglandular anal fistulas were eligible for inclusion. RESULTS A total of 11 articles with 810 patients were included in this meta-analysis. Four RCTs and one observational clinical study provided long-term follow-up. The pooled analysis of all 11 studies indicated that there was no significant difference between the AFP and RAF in terms of healing rate, recurrence rate and incidence of fistula complications. However, the pooled results of studies with long-term follow-up revealed that the RAF group had a significantly higher healing rate (OR 0.32, 95% CI 0.13, 0.78, P = 0.01) and lower recurrence rate (OR 4.45, 95% CI 1.45, 13.65, P = 0.009) than the AFP group. CONCLUSIONS For the treatment of complex cryptoglandular anal fistulas, the RAF was superior to the AFP in terms of healing and recurrence rate after pooling of randomized controlled trials with long-term follow-up, even though a comparison based on the pooling of all studies showed no significant difference.

Abstract
BACKGROUND Surgical management of complex perianal fistula associated with pararectal cavities can be challenging. We hypothesised that healing of the pararectal cavities prior to healing of the fistula leads to a better outcome. We aimed to assess the efficacy of irrigation catheters in the healing of pararectal cavities associated with fistula-in-ano. METHODS This study design was consistent with IDEAL stage 2a (development) and was conducted at the Professorial Surgical Unit, National Hospital of Sri Lanka, Colombo. Thirty-two patients with complex fistulae with a pararectal cavity (detected by 2D-Endoanal ultrasounography-EAUS) were included. All patients underwent examination under anaesthesia (EUA), during which insertion of an irrigation catheter to the pararectal cavity and tagging of the primary fistula tract with a drainage seton was done. Patients were advised to irrigate with antiseptic solution and were followed-up at three weekly intervals to assess cavity reduction. RESULTS The majority were males (96.8%, n = 31). The primary fistula tract in 26 patients (81.2%) was trans-sphincteric and was inter-sphincteric in 6 patients (18.7%). Mean time of cavity contraction was 34.78 (range, 21-112) days. Complete healing was seen in 87.5% (n = 28), with 3 patients (9.37%) being lost to follow-up and 1 patient (3.12%) having a persistent perianal fistula after 6 months of follow-up. Those who had complete healing were followed up for a median duration of 6 (range, 3-20) months and there were no recurrences. CONCLUSIONS Irrigation in the management of pararectal cavities yielded satisfactory results. A case control trial with larger numbers and assessment of cavity size pre and post procedure by 3D-EAUS/MRI evaluation would be necessary for more objective evaluation of the efficacy of this novel intervention.

Abstract
Objectives Surgery for fistula in ano is associated with anal incontinence. The biologic anal fistula plug (AFP) can minimize this. This is a retrospective analysis of patients with cryptoglandular anorectal fistulae, who underwent a surgical procedure using AFP. Patient’s demographics and characteristics of the fistulae were obtained from a prospective database. Each primary opening was occluded by using an AFP. Success was defined by the closure of the external opening and absent drainage. Results Fifty-one patients were treated with AFP (male:female: 37:14), mean age 42 years (SD ± 14.86, range 26–70). Ten patients defaulted follow-up. Forty-seven procedures were analysed. Twenty-three (56.1%) patients had complete healing while 18 (43.9%) patients failed the fistula plug procedure during the follow up period of 12 months. Logistical regression failed to identify any statistical significant association with demographic or disease factors and healing. Healing was 1.5 times less likely for every failed procedure prior to AFP insertion. Contrary to other published studies, placement of fistula plug was associated with much lower overall rates of fistula healing. Highest success rates were seen in simple fistulae when compared to the complex type. Repeat plug placement may be successful in selected patients.

Abstract
Innovation can be variably defined, but when applied to healthcare is often considered to be the introduction of something new, whether an idea, method or device, into an unfilled void or needy environment. Despite the introduction of many positive surgical subspecialty altering concepts/devices however, epic failures are not uncommon. These failures can be dramatic in regards to both their human and economic costs. They can also be very public or more quiet in nature. As surgical leaders in our communities and advocates for patient safety and outcomes, it remains crucial that we meet new introductions in technology and patient care with a measured level of curiosity, skepticism and science-based conclusions. The aim of an expert committee was to identify the most dominant failures in technological innovation and/or dogmatic clinical beliefs within each major surgical subspecialty. In summary, this effort was pursued to highlight the past failures and remind surgeons to remain vigilant and appropriately skeptical with regard to the introduction of new innovations and clinical beliefs within our craft.

Abstract
AIM: To evaluate the safety of the implantation of a new device for the treatment of anal fistulas. The short-term clinical efficacy was also assessed.
METHODS: This study took place at a tertiary care university hospital. Patients with a complex anal fistula of cryptoglandular origin were enrolled in the study and were treated with insertion of the new device. All patients were evaluated by clinical and physical examination, including an endoanal ultrasound at the baseline, and then at the 2 wk and 1, 2, 3 and 6-mo follow-up visits.
RESULTS: Morbidity, continence status, and success rate were the main outcome measures. Ten patients underwent the placement of the new device. The fistulas were transphincteric in eight patients and extrasphincteric in the remaining two. The median duration of the surgical procedure was 34.5 (range, 27-42) min. Neither intra- nor postoperative complications occurred, and all patients were discharged the day after the procedure. At the 6-mo follow-up evaluation, the final success rate was 70%. Three failures were registered: a device expulsion (on the 10th postoperative day), the persistence of inflammatory tissue around the fistula tract (at the 2-mo follow up), and the persistence of serum discharge (at the 6-mo follow up). No patient experienced any change incontinence, as assessed by the Cleveland Clinic Fecal Incontinence score.
CONCLUSION: The technical procedure is simple and has low risk of perioperative morbidity. The pre- and post-operative continence status did not change in any of the patients. The initial results at the 6-mo follow up seem to be promising. However, a longer follow-up period and a larger sample size are needed to confirm these preliminary results.

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
Introduction 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. Material and Methods PubMed, Medline, Embase, and the Cochrane medical database were searched up to July 2015. Sixty-four articles were relevant for this review. Results 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. Discussion 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.

Abstract
AIM The study aimed to compare the rate of success and cost of anal fistula plug (AFP) insertion and endorectal advancement flap (ERAF) for anal fistula. METHOD Patients receiving an AFP or ERAF for a complex single fistula tract, defined as involving more than a third of the longitudinal length of of the anal sphincter, were registered in a prospective database. A regression analysis was performed of factors predicting recurrence and contributing to cost. RESULTS Seventy-one patients (AFP 31, ERAF 40) were analysed. Twelve (39%) recurrences occurred in the AFP and 17 (43%) in the ERAF group (P = 1.00). The median length of stay was 1.23 and 2.0 days (P < 0.001), respectively, and the mean cost of treatment was €5439 ± €2629 and €7957 ± €5905 (P = 0.021), respectively. On multivariable analysis, postoperative complications, underlying inflammatory bowel disease and fistula recurring after previous treatment were independent predictors of de novo recurrence. It also showed that length of hospital stay ≤ 1 day to be the most significant independent contributor to lower cost (P = 0.023). CONCLUSION Anal fistula plug and ERAF were equally effective in treating fistula-in-ano, but AFP has a mean cost saving of €2518 per procedure compared with ERAF. The higher cost for ERAF is due to a longer median length of stay.

Abstract
Anal fistulas are difficult to treat because they are often recalcitrant to medical therapies and surgical treatment may lead to significant morbidities. A recent novel biologically derived graft from porcine urinary bladder (MatriStem™) has shown great promise in experimental studies of tissue regeneration in diverse tissues. The objectives of this study were to evaluate the safety and short-term efficacy of MatriStem for treatment of anal fistulas. This was a retrospective study of patients treated from January 3, 2012 to March 3, 2014 at the University of Pittsburgh Medical Center. MatriStem was used to treat patients with anal fistulas by implanting it uniformly with a single application in all patients using a standardized protocol. Data were collected retrospectively from hospital records and office charts. Nineteen fistulas were treated with MatriStem. There were no adverse complications. Overall efficacy of MatriStem was 79 per cent with healing occurring in a mean time of 17 days and mean follow-up of seven months (range 1–26 months). MatriStem was effective in healing in 75 per cent of primary anal fistulas and 86 per cent of recurrent fistulas. MatriStem seems to be a safe and promising treatment for primary and recurrent anal fistulas, and warrants further study and clinical trials to substantiate widespread clinical use.

[PMID: 25850629 DOI: 10.1007/s10151-015-1299-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2014] [Accepted: 02/05/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND The aim of the present study was to assess a novel autologous cartilage plug technique used to treat anal fistula in ten patients. METHODS All ten patients had undergone at least two prior operations for recurrent fistulas. The plugs were prepared using the patients' own cartilage, which was obtained from either the nose or the ear, diced into pieces, and wrapped with oxidized regenerated cellulose. During the same session, fistula tracts were curetted using cytology brushes, and then, the cartilage plug was inserted into the tract. Routine postoperative examinations were performed at 2, 4, 8, 12, and 24 weeks after surgery. Magnetic resonance imaging was performed before surgery and at 3 and 6 months postoperatively. Relief of symptoms, radiological healing, recurrence, and continence were evaluated. RESULTS The ten patients included six males and four females, with a median age of 39 years (range 25-70 years) and a median of three previous fistula operations (range 2-7 operations). Nine patients had cryptoglandular abscess, and one patient had Crohn's disease. The majority of the patients had transsphincteric fistulas with substantial anal sphincter involvement. The cartilage donor site was the nose for one patient and the ear for nine patients. The median follow-up time was 24 months (range 10-32 months). Of the ten patients, nine had fistula treatment without any short-term complications. The fistula failed to heal in one patient. Among the nine patients whose operations were initially successful, two late recurrences were observed. CONCLUSIONS The cartilage plug seems to be a promising alternative for anal fistula treatment.

Abstract
BACKGROUND Although interest in sphincter-sparing treatments for anal fistulas is increasing, few large prospective studies of these approaches have been conducted. OBJECTIVE The study assessed outcomes after implantation of a synthetic bioabsorbable anal fistula plug. DESIGN A prospective, multicenter investigation was performed. SETTING The study was conducted at 11 colon and rectal centers. PATIENTS Ninety-three patients (71 men; mean age, 47 years) with complex cryptoglandular transsphincteric anal fistulas were enrolled. Exclusion criteria included Crohn's disease, an active infection, a multitract fistula, and an immunocompromised status. INTERVENTION Draining setons were used at the surgeon's discretion. Patients had follow-up evaluations at 1, 3, 6, and 12 months postoperatively. MAIN OUTCOME MEASURES The primary end point was healing of the fistula, defined as drainage cessation plus closure of the external opening, at 6 and 12 months. Secondary end points were fecal continence, duration of drainage from the fistula, pain, and adverse events during follow-up. RESULTS Thirteen patients were lost to follow-up and 21 were withdrawn, primarily to undergo an alternative treatment. The fistula healing rates at 6 and 12 months were 41% (95% CI, 30%-52%; total n = 74) and 49% (95% CI, 38%-61%; total n = 73). Half the patients in whom a previous treatment failed had healing. By 6 months, the mean Wexner score had improved significantly (p = 0.0003). By 12 months, 93% of patients had no or minimal pain. Adverse events included 11 infections/abscesses, 2 new fistulas, and 8 total and 5 partial plug extrusions. The fistula healed in 3 patients with a partial extrusion. LIMITATIONS The study was nonrandomized and had relatively high rates of loss to follow-up. CONCLUSION Implantation of a synthetic bioabsorbable fistula plug is a reasonably efficacious treatment for complex transsphincteric anal fistulas, especially given the simplicity and low morbidity of the procedure.

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
In colorectal surgery, eradicating the fistula and maintaining continence are still complex challenges for a colorectal surgeon. A minimally invasive method using a novel device was performed to consecutively treat 14 patients with anal fistula from August 2008 to November 2009. After a follow-up period of 36 months, 13 patients achieved successful closure of their fistula tracts, and recurrence occurred only in one patient. Recurrence was due to the delay of dressing change. No patient had interference with continence, and no major intra- and postoperative complications were identified. Using the novel device with invasive methods can be a promising alternative for managing anal fistulas.
