Abstract
Objectives Fistula-in-ano is a common condition that negatively affects the quality of life of its sufferers. A high anal fistula poses a significant challenge for surgeons due to its proximity to the anorectal ring and the potential risk of incontinence rather than recurrence. Many modalities have been used in a justified search for a satisfactory cure for the condition, but the seton remains a mainstay of surgical treatment. Therefore, the rationale of this study is to assess the outcome of treating a high anal fistula using the cutting seton technique in a hospital in Al Madinah, Saudi Arabia. The evaluation is intended through a retrospective analysis of patients' outcomes, comparing its effectiveness to similar articles. Methods This is a retrospective study that includes 50 patients with high anal fistulas who were treated with a cutting seton at the National Guard Hospital over a four-year period (2019-2022). Information obtained from medical records included clinical and demographic data. The data collected during the study was compiled and statistically analyzed using the SPSS Statistics version 26.0 (IBM Corp. Released 2019. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY: IBM Corp.). A p-value of <0.05 was considered statistically significant. Results A total of 50 patients with high anal fistula treated with a cutting seton were included: 82% were males and 18% were females, with 66% below 45 years of age. Approximately 92% had inter-sphincteric fistulas, and only 28% had a recurrent fistula. Almost all patients (98%) had an MRI done before surgery. Around 70% of patients were completely cured, 26% had minor complications, 8% of the operated patients experienced mild incontinence, and only one recurrence (2%). Conclusion The cutting seton is still a valid modality in treating patients with a high anal fistula, as it is considerably safe, effective, and yields good outcomes. Standard preoperative assessment and thorough surgical techniques are cornerstones for achieving a satisfactory outcome.

A comparative study between high ligation of the inter-sphincteric fistula tract via lateral Approach Versus Fistulotomy and primary sphincteroplasty in High Trans-Sphincteric Fistula-in-Ano: a randomized clinical trial. BMC Surg 2023; 23:224. [PMID: 37559044 PMCID: PMC10413541 DOI: 10.1186/s12893-023-02117-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Accepted: 07/21/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Trans-sphincteric fistula management is very challenging and everyday new techniques are introduced to reach the safest and the most effective technique. In this study two of the most effective techniques are compared based on their post-operative outcomes. OBJECTIVE To compare the efficacy of high ligation of the inter-sphincteric fistula tract by lateral approach (modified LIFT) and Fistulotomy and primary sphincteroplasty (FIPS) in the management of high trans-sphincteric fistula regarding their post-operative outcomes in the form of post-operative pain, time of wound healing in weeks, wound infection, incontinence and recurrence within one year. PATIENTS AND METHODS The current study is single-blind, prospective, randomized, controlled, single-center trial conducted from June 2020 to June 2022 in the colorectal surgical unit of Ain Shams University Hospitals, which included 80 patients presented with high trans-sphincteric perianal fistula 55 (68.75%) males and 25 (31.25%) including a one-year follow-up postoperative. RESULTS There were 80 patients in our study 40 patients in each group. The mean age of group (I) is 46.65 with standard deviation 6.6. while, in group (II) the mean age is 45.85 with standard deviation 6.07 (p = 0.576). From the included 80 patients 55(68.7%) were males and 25 (31.25%) were females (p = 0.469). Regarding, postoperative wound infection occurred in 2(5%) Patients in group (I) and 7(17.5%) patients in group (II) (p = 0.154). There were no cases of incontinence in group I. However, there were 6(15%) cases of incontinence to gases only scored by Wexner score 3/20 in group II (p = 0.026) and its significant difference between the two techniques. Postoperative pain was assessed for one week duration by the visual analogue score (VAS) from 0 to 10 in which, zero is the least and 10 is the maximum. In group (I) 18(45%) patients scored their pain mild from 1 to 3, 20(50%) patients scored their pain moderate from 4 to 6 and 2(5%) patients scored severe pain from 7 to 9. While, in group (II) 14(35%) patients scored their pain mild from 1 to 3, 22(55%) patients their pain moderate from 4 to 6 and 4(10%) patients scored their pain severe from 7 to 9 (p = 0.275). Recurrence in one-year follow-up occurred in 13(32.5%) patients in group (I) about 7 patients had recurrence in the form of inter-sphincteric fistula and 6 patients in the form of trans-sphincteric fistula. While, in group II recurrence occurred in 1 (2.5%) patient in the form of subcutaneous fistula at the healing site (p = 0.001). CONCLUSION Fistulotomy and primary sphincteroplasty is an effective and preferred technique for the trans-sphincteric fistula repair with high statistically significant lower incidence of recurrence in one-year follow-up as compared to modified LIFT technique. Although, there is higher incidence regarding incontinence to gases only post-operative. This work recommends fistulotomy and primary sphincter reconstruction procedure in high trans-sphincteric perianal fistulas to be more popular, to be implemented as a corner stone procedure along various and classic operations for such cases as it's easy, feasible.

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.

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
OBJECTIVES Complex perianal fistulas (CPFs) in children even in the absence of luminal symptoms prompt evaluation for Crohn's disease (CD). Reports of isolated CPF in children, however, are sparse. In perianal CD, antitumor necrosis factor α (anti TNF) therapy is recommended. We aimed to describe our experience with anti TNF therapy in children with isolated CPF without evidence of luminal CD. METHODS We retrospectively reviewed charts of patients with isolated CPF who were treated with anti TNF agents between 2011 and 2019 in a tertiary center. MRI pelvis findings at baseline versus end of follow up were scored using MAGNIFI-CD. Outcomes included clinical remission, radiological response and radiological remission based on MAGNIFI-CD score at end of follow up. RESULTS Overall, 17 patients were identified, [10 males (59%), mean age at anti TNF initiation 13.4 ± 2.9 years]. Median time from perianal disease onset to anti TNF was 16.5 months (IQR 9.4-36.4). None of the patients had luminal inflammation. Prior to anti TNF, all patients had been treated with antibiotics without sufficient improvement, and 9/17 with abscess drainage and or Seton insertion. Nine patients (53%) were treated with infliximab while 8 (47%) received adalimumab. Median duration of follow up was 30.7 months (IQR = 12.7-44.8). At the end of follow up 9 patients (53%) achieved clinical remission. When comparing MRI prior to and after anti TNF, 36% (5/14) had radiologic response, of whom 2 (14%) achieved radiologic resolution. CONCLUSION Anti TNF agents may be an effective treatment option for children with isolated CPF. Whether these patients should be considered part of the CD phenotypic spectrum or a distinct entity is unclear. LEVELS OF EVIDENCE Therapeutic.

Abstract
Abstract
Background Fistula in ano is a very common perianal condition seen in outpatient departments. Fistulotomy and fistulectomy are two conventional options of surgery. The present study is designed to observe wound healing time and mean postoperative pain score in the comparison of outcome of the fistulectomy to fistulotomy with marsupialization.
Methods This prospective randomized trial was conducted in the surgical department of the Civil Hospital Karachi for a period of 12 months, in which 60 patients with low anal fistula were divided into 2 groups. Thirty patients in group A were treated with fistulectomy, and 30 in group B were treated with fistulotomy with marsupialization. The postoperative pain severity was assessed after 24 hrs through a visual analogue scale and on weekly and fortnightly follow-ups for 6 weeks. Wound healing was assessed by clinical examination on weekly and fortnightly follow-ups for 6 weeks to estimate the mean healing time.
Results The mean pain score was significantly lower in group B in comparison to group A (3.6 ± 1.99 versus 2.40 ± 1.52; p = 0.01). The mean wound healing time was shorter in group B in comparison to group A (4.23 ± 0.77 versus 5.80 ± 0.41 weeks; p = 0.0005).
Conclusion Fistulotomy with marsupialization is a simple, easy, and more effective method than fistulectomy for the treatment of simple perianal fistula.

Abstract
Despite current management strategies, digestive fistulae remain extremely debilitating complications associated with significant morbidity and mortality, generating a need to develop innovative therapies in these indications. A number of clinical trials and experimental studies have thus investigated the potential of stem/stromal cells (SCs) or SC-derived extracellular vesicles (EVs) administration for post-surgical and Crohn's-associated fistulae. This review summarizes the physiopathology and current standards-of-care for digestive fistulae, along with relevant evidence from animal and clinical studies regarding SC or EV treatment for post-surgical digestive fistulae. Additionally, existing preclinical models of fistulizing Crohn's disease and results of SC therapy trials in this indication will be presented. The optimal formulation and administration protocol of SC therapy products for gastrointestinal fistula treatment and the challenges for a widespread use of darvadstrocel (Alofisel) in clinical practice will be discussed. Finally, the potential advantages of EV therapy and the obstacles towards their clinical translation will be introduced.

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.

Abstract
Background Achieving a complete cure while maintaining continence constitutes a considerable challenge in the treatment of patients with high anal fistula. This study aimed to evaluate the effectiveness of loose combined cutting seton (LCCS) for treating patients with high intersphincteric fistula. Methods Consecutive patients with high intersphincteric fistula who underwent LCCS were retrospectively enrolled. Patient data including demographics, medical history, comorbidities, details of the fistula, operative procedure, and prognosis were collected. Postoperative pain was assessed using a visual analog scale (VAS), which ranged from 0 (no pain) to 10 (extremely severe pain). The severity of fecal incontinence was assessed using the Wexner Continence Grading Scale, with a total score ranging from 0 (no incontinence) to 20 (complete incontinence). The primary outcome was the healing rate of fistula. Secondary outcomes included the recurrence rate of fistula and the severity of fecal incontinence. Results The 22 patients (male: female =18:4) in our study had a median follow-up of 55 (range, 32–568) days. The healing rate was 100%, and none of the patients experienced fistula recurrence. At the follow-up visit, 19 patients (86.4%) reported no fecal incontinence. The median total Wexner score was 0. 95.5% patients had VAS score of 0 and only 1 patient (4.5%) had a VAS score of 1, which indicated a low level of postoperative pain. Conclusions LCCS achieved a high healing rate with an increased level of continence, as well as a low level of postoperative pain, in most patients with high anal fistula in our study. Further randomized controlled trials are needed to confirm the effectiveness of this novel seton-based technique.

Abstract
Idiopathic cryptoglandular fistula-in-ano is a common pathological condition. Fistula-in-ano has been managed by a number of surgical techniques, and there is still no consensus regarding the management of this condition. Surgical techniques aim to treat and cure the fistula-in-ano with minimal risk of recurrence or complications, and to maintain patient continence. This article discusses the evidence available to inform the management of idiopathic cryptoglandular fistula-in-ano, and problems that surgeons face because of the lack of high-quality evidence.

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
BACKGROUND Management of transsphincteric cryptoglandular fistulas remains a challenging problem and the optimal surgical approach remains elusive. Mesenchymal stem cells, increasingly being utilized for perianal Crohn's disease, offer a novel therapy to treat cryptoglandular fistulas. OBJECTIVES This study aimed to determine safety and feasibility of using an autologous mesenchymal stem cell-coated fistula plug in patients with transsphincteric cryptoglandular fistulas. DESIGN This study is a phase I clinical trial. SETTING This study was conducted at a tertiary academic medical center. PATIENTS Adult (>18 years) male and female patients with transsphincteric cryptoglandular fistulas were selected. MAIN OUTCOMES MEASURES The primary outcomes measured were the safety, feasibility, and efficacy of a mesenchymal stem cell-coated fistula plug in patients with transsphincteric fistulas. RESULTS Fifteen patients (8 women, mean age 39.8 years) with a single-tract transsphincteric fistula received a mesenchymal stem cell-loaded fistula plug and were followed for 6 months. Duration of disease at the time of study enrollment was a median of 3.0 years (range, 1-13 years) with a median of 3.5 (range, 1-20) prior surgical interventions. Adverse events included 1 plug extrusion, 1 abdominal wall seroma, 3 perianal abscesses requiring drainage, and 1 patient with perianal cellulitis. There were no serious adverse events. At 6 months, 3 patients had complete clinical healing, 8 had partial healing, and 4 patients showed no clinical improvement. Radiographic improvement was seen in 11 of 15 patients. LIMITATIONS This study was limited by the small cohort and short follow-up. CONCLUSIONS Autologous mesenchymal stem cell-coated fistula plug treatment of transsphincteric cryptoglandular fistulas was safe and feasible and resulted in complete or partial healing in a majority of patients.

Abstract
AIM To establish and evaluate an experimental porcine model of fistula-in-ano.
METHODS Twelve healthy pigs were randomly divided into two groups. Under general anesthesia, the experimental group underwent rubber band ligation surgery, and the control group underwent an artificial damage technique. Clinical magnetic resonance imaging (MRI) and histopathological evaluation were performed on the 38th d and 48th d after surgery in both groups, respectively.
RESULTS There were no significant differences between the experimental group and the control group in general characteristics such as body weight, gender, and the number of fistula (P > 0.05). In the experimental group, 15 fistulas were confirmed clinically, 13 complex fistulas were confirmed by MRI, and 11 complex fistulas were confirmed by histopathology. The success rate in the porcine complex fistula model establishment was 83.33%. Among the 18 fistulas in the control group, 5 fistulas were confirmed clinically, 4 complex fistulas were confirmed by MRI, and 3 fistulas were confirmed by histopathology. The success rate in the porcine fistula model establishment was 27.78%. Thus, the success rate of the rubber band ligation group was significantly higher than the control group (P < 0.05).
CONCLUSION Rubber band ligation is a stable and reliable method to establish complex fistula-in-ano models. Large animal models of complex anal fistulas can be used for the diagnosis and treatment of anal fistulas.

Abstract
Tumours of the anal and perianal region are relatively rare, and clinically often interpreted as innocuous lesions, leading to frequent delays in diagnosis and adequate treatment. Although squamous cell neoplasia represents the most common entity encountered in this anatomically complex area, many conditions, both neoplastic and inflammatory, may occur. Adding to the challenge of correct diagnosis and patient management, recent years have seen major updates in the terminology of squamous cell neoplasia, created to reflect advances in our understanding of the role of human papilloma virus and unify previous terminologies used for different sites in the anogenital tract. However, squamous cell neoplasia in the anal canal and perianal region may differ in terms of histology, biological behaviour, staging and treatment. The aim of this review is to present an overview of neoplastic and non-neoplastic lesions that may be seen in this area, an update on important developments and terminology, potential pitfalls that may be encountered in routine pathology practice and a practical approach on how to resolve these issues.

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
BACKGROUND Fistula-tract Laser Closure (FiLaC™) is a sphincter-saving technique for the treatment of anal fistulas that has been shown to be successful in the short and middle term. However, the long-term success rate is unknown. This study aimed to report long-term results in performing FiLaC™. METHODS This study was performed as a retrospective observational study. Forty-five patients who underwent FiLaC™ between July 2010 and May 2014 were evaluated. In all cases, FiLaC™ was performed with a diode laser at a wavelength of 1470 nm by means of a radial fiber. Patients and fistula characteristics, previous treatments, healing rates, failures and postoperative incontinence were reviewed. RESULTS Median follow-up time was 30 months (range 6-46 months). Thirty-five patients (78%) had a history of previous surgery for their fistulas. Primary healing was observed in 32 patients (71.1%), and the median healing time was 5 weeks (range 3-8 weeks). Eleven of the 13 failures (85%) were early failures (persistent symptoms). No patient reported postoperative incontinence. The best healing rate was observed in patients who had been previously treated with loose seton (19/24, 79%). CONCLUSIONS Long-term follow-up after FiLaC™ seems to confirm the favorable short-term success rates reported for this procedure. Although sealing of chronic anal fistulas may be obtained with FiLaC™ in a single treatment, our current strategy consists of placing a loose seton into the fistula tract a few weeks prior to laser treatment. Seton treatment facilitates the following laser procedure and seems to have favorable effects on healing.

Abstract
Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract, whilst preserving the sphincters and the mechanism of continence. For the simple and most distal fistulae, conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore, well accepted in clinical practise. However, for the more complex fistulae where a significant proportion of the anal sphincter is involved, great concern remains about damaging the sphincter and subsequent poor functional outcome, which is quite inevitable following conventional surgical treatment. For this reason, over the last two decades, many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function. Among them, the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula. Another technique, the anal fistula plug, derived from porcine small intestinal submucosa, is safe but modestly effective in long-term follow-up, with success rates varying from 24%-88%. The failure rate may be due to its extrusion from the fistula tract. To obviate that, a new designed plug (GORE BioA®) was introduced, but long term data regarding its efficacy are scant. Fibrin glue showed poor and variable healing rate (14%-74%). FiLaC and video-assisted anal fistula treatment procedures, respectively using laser and electrode energy, are expensive and yet to be thoroughly assessed in clinical practise. Recently, a therapy using autologous adipose-derived stem cells has been described. Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae, and studies remain in progress. The aim of this present article is to review the pertinent literature, describing the advantages and limitations of new sphincter-preserving techniques.

Abstract
Anal fistula (AF) presents a chronic problem for patients and colorectal surgeons alike. Surgical treatment may result in impairment of continence and long-term risk of recurrence. Treatment options for AFs vary according to their location and complexity. The ideal approach should result in low recurrence rates and minimal impact on continence. New technical approaches involving biologically derived products such as biological mesh, fibrin glue, fistula plug, and stem cells have been applied in the treatment of AF to improve outcomes and decrease recurrence rates and the risk of fecal incontinence. In this review, we will highlight the current evidence and describe our personal experience with these novel approaches.

Abstract
We report a case of chronic arthritis of the right hip joint in an otherwise healthy young male athlete as a complication of inadequately treated anal fistula. A young male athlete presented with symptoms of right hip pain and difficulty in walking and intermittent fever for 2 months. He had a history of perianal abscess drainage. On examination he was found to have a tender right hip joint with severe restriction of movements. He was also found to have a partially drained right ischiorectal abscess. X-ray and MRI of the hip joint revealed chronic arthritis of the right hip joint, which was communicating with a complex fistula-in-ano. He underwent a diversion sigmoid colostomy and right ischiorectal abscess drainage along with appropriate antibiotics with a plan for definitive hip joint procedure later. He was lost to follow-up and succumbed to severe perianal sepsis within a few months.

Abstract
Anal fistula management has long been a challenge for surgeons. Presently, no technique exists that is ideal for treating all types of anal fistula, whether simple or complex. A higher incidence of poor sphincter function and recurrence after surgery has encouraged the development of a new sphincter-sparing procedure, ligation of the intersphincteric fistula tract (LIFT), first described by Van der Hagen et al. in 2006. We assessed the safety, feasibility, success rate, and continence of LIFT as a sphincter-saving procedure. A literature search of articles in electronic databases published from January 2006 to August 2012 was performed. Analysis followed Preferred Reporting Items for Systematic Reviews recommendations. All LIFT-related articles published in the English language were included. We excluded case reports, abstracts, letters, non-English language articles, and comments. The procedure was described in detail as reported by Rojanasakul. Thirteen original studies, including 435 patients, were reviewed. The most common fistula procedure type was transsphincteric (92.64 %). The overall median operative time was 39 (±20.16) min. Eight authors performed LIFT as a same-day surgery, whereas the others admitted patients to the hospital, with an overall median stay of 1.25 days (range 1-5 days). Postoperative complications occurred in 1.88 % of patients. All patients remained continent postoperatively. The overall mean length of follow-up was 33.92 (±17.0) weeks. The overall mean healing rate was 81.37 (±16.35) % with an overall mean healing period of 8.15 (±5.96) weeks. Fistula recurrence occurred in 7.58 % of patients. LIFT represents a new, easy-to-learn, and inexpensive sphincter-sparing procedure that provides reasonable results. LIFT is safe and feasible, with favorable short- and long-term outcomes. However, additional prospective randomized studies are required to confirm these findings.

BACKGROUND Management of anal fistulas is challenging, because surgeons must aim to obtain complete healing while sparing the sphincter and avoiding fecal incontinence. The optimal treatment method remains unknown. OBJECTIVE This study assessed the safety and effectiveness of the use of a new synthetic fistula plug made of bioabsorbable polymers in the treatment of cryptoglandular anal fistulas. DESIGN This study is a retrospective review of a database of patient records. SETTING : Patients were treated at a general hospital in Italy. PATIENTS Forty-eight patients (39 men and 9 women; mean age, 49.9 years) with 49 fistulas were treated with the synthetic plug between November 2009 and March 2012. Types of fistula were as follows: 24 superficial transsphincteric, 18 medium transsphincteric, 5 deep transsphincteric, and 1 medium intersphincteric. INTERVENTIONS The fistula tract was cleaned by using curettage, and a synthetic plug was sized to fit the tract and inserted. A draining seton was used preoperatively in 1 patient. MAIN OUTCOME MEASURES The outcome measures were complete closure of the fistula, with no discharge/residual fistula (verified by endoanal ultrasonography), perineal pain level (assessed with a visual analog scale), and fecal continence. Follow-up was conducted at 1 week and 1, 3, 6, and 12 months postoperatively. RESULTS The overall healing rate was 69.3% (34/49 fistulas, 33/48 patients). Eight patients (24.2%) had healing by 3 months after surgery, 21 patients (63.6%) had healed by 6 months, and 4 patients (12.1%) had healed by 12 months. By 3 months, no patient had perineal pain or fecal incontinence. No plug became dislodged, and no patient had the onset of anal stenosis, bleeding, local infection, or any other complication. LIMITATIONS The number of patients and the retrospective nonrandomized nature of the investigation are limitations of this study. CONCLUSIONS In patients with cryptoglandular anal fistulas, the use of a bioabsorbable synthetic plug provided a high rate of healing without causing fecal incontinence or other major adverse effects. Larger and randomized studies of this treatment are warranted.

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 The mostly widely studied biomaterials for the sphincter sparing treatment of anal fistulas are fibrin glue and the anal fistula plug (AFP). However their overall mean clinical success is only 50-60%. As the understanding of the pathology of anal fistula, wound healing and the host response to materials has improved, so new biological sphincter-sparing strategies have been developed. The aim of this review is to assess the safety and efficacy of these novel techniques. METHOD PubMed, the Cochrane database and EMBASE were independently searched. All studies that investigated the potential of a biomaterial (defined as any synthetic or biologically derived substance in contact with host tissue) to augment the healing of anal fistula without sphincter division were included. Studies solely describing the role of fibrin glue or an AFP were excluded. Data extraction included type of material, fistula aetiology, treatment of the primary tract, fistula healing, incontinence, duration of follow-up and any specific complications. Systematic quality assessment of the included articles was performed. RESULTS Twenty-three articles were finally selected for review. These included a variety of biological and synthetic systems that were employed to deliver selected components of the extracellular matrix, growth factors, cytokines, stem cells or drugs to the fistula tract. CONCLUSION To date no study matches fistulotomy with regard to long-term fistula eradication rate. This is probably due to implant extrusion, inadequate track preparation or an unsuitable material. Future techniques need to address all these issues to ensure success. Success should be validated by MRI or long-term follow-up.

Abstract
BACKGROUND The management of fistula-in-ano is a balance between fistula cure and preservation of continence. OBJECTIVE The aim of this study is to summarize the anal fistula plug literature for Crohn's and non-Crohn's fistula-in-ano in a homogenous patient population. DATA SOURCES PubMed, MEDLINE, Embase, and Cochrane medical databases were searched from 1995 to 2011. Abstracts from The American Society of Colon and Rectal Surgeons, The Society for Surgery of the Alimentary Tract, The European Society of Coloproctology, and the Association of Coloproctology of Great Britain and Ireland meetings between 2007 and 2010 were also evaluated. STUDY SELECTION Studies were included if results for patients with and without Crohn's disease could be differentiated. Patients with rectovaginal, anovaginal, rectourethral, or ileal-pouch vaginal fistulas were excluded as were studies where the mean or median follow-up was less than 3 months. Two researchers independently selected studies matching the inclusion criteria. INTERVENTION Anal fistula plug insertion was performed. MAIN OUTCOME MEASURES The primary outcomes measured were the overall fistula closure rates and length of follow-up. RESULTS Seventy-six articles or abstracts were identified from the title as being of relevance. Twenty studies (2 abstracts, 18 articles) were finally included. Study sample size ranged from 4 to 60 patients; 530 patients were included in all studies (488 non-Crohn's and 42 Crohn's patients). The plug extrusion rate was 8.7% (46 patients). The proportion of patients achieving fistula closure varied widely between studies for non-Crohn's, ranging from 0.2 (95% CI 0.04-0.48) to 0.86 (95% CI 0.64-0.97). The pooled proportion of patients achieving fistula closure in patients with non-Crohn's fistula-in-ano was 0.54 (95% CI 0.50-0.59). The proportion achieving closure in patients with Crohn's disease was similar (0.55, 95% CI 0.39-0.70). LIMITATIONS This study was limited by the variability of operative technique and perioperative care between studies. CONCLUSIONS Fistula closure is achieved by using the anal fistula plug in approximately 54% of patients without Crohn's disease. The anal fistula plug has not been adequately evaluated in the Crohn's population.
