Abstract
PURPOSE To investigate the ability of a "slowly cutting, loose seton ligature and staged fistulotomy" to heal perianal fistulas, the time needed with the seton ligature, recurrence rate, influence on anal continence, health-related quality of life (HRQoL), and patient satisfaction. METHODS Observational single-center study. We reviewed the medical records of all patients with primary surgeries from January 1, 2009, to December 31, 2018. The patients answered a questionnaire pre- and postoperative on anal continence (St. Mark's incontinence score) and HRQoL (The Short Health Scale). Satisfaction with the operation was answered postoperatively. RESULTS Forty-three patients (37 men, 6 women) were included. Initially 41 of 43 healed (95%). Three patients (7%) had a recurrence, two healed after retreatment. The median follow-up was 55 months (IQR, 4). Thirty-four patients (79%) responded to the questionnaire. At follow-up, forty (93%) patients were healed. The median time treated with a seton ligature in the healed patients was 13 months (IQR, 14). St. Mark's incontinence score preoperative was median 2 (IQR, 9) and after the operation median 1 (IQR, 4). The Short Health Scale improved from median 20 (IQR, 5) preoperatively to 5 (IQR, 5) postoperatively, p < 0.001. Patient satisfaction was median 1 (= very satisfied) (IQR, 1). CONCLUSION A "slowly cutting, loose seton ligature followed by a staged fistulotomy", heals the vast majority of perianal fistulas with minor or none influence on continence and few recurrences. Patient-reported HRQoL improves greatly, and patient satisfaction is high.

Abstract
OBJECTIVE This study aimed to investigate the clinical value of combined serum matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) for the prognosis of perianal fistula patients. METHODS Patients diagnosed and treated for perianal fistula by minimally invasive surgery (MIS) were enrolled. The concentrations of serum MMP-2, MMP-9 and TIMP-1 were measured at 24 h after surgery. Different levels of wound secretion, growth of granulation tissue and wound pain were used as criteria to evaluate surgical incision healing. The receiver operating characteristic curve was used to analyze the predicted assessment value. RESULTS The concentrations of serum MMP-2 and MMP-9 were significantly higher, while the concentrations of serum TIMP-1 at 24 h after surgery were significantly lower in the poor healing group than in the good healing group. It was further found that high levels of serum MMP-2 and MMP-9 were risk factors for poor healing, while high concentrations of serum TIMP-1 at 24 h after surgery were protective factors for poor healing. CONCLUSION High concentrations of serum MMP-2 and MMP-9 and low concentrations of serum TIMP at 24 h after surgery are risk factors for poor healing in perianal fistula patients who receive MIS, and the combined test has a higher predictive value.

Abstract
Anal fistula is a common proctological disease, but the thorough mechanisms of the anal fistula formation are still unclear. An increasing number of studies have revealed the crucial role of gut microbiota in intestinal diseases. We used 16S rRNA gene sequencing to analyze the intestinal microbiome in order to determine whether there are differences in the microbiome between anal fistula patients and healthy individuals. The microbiome samples were extracted by repeatedly wiping the rectal wall with intestinal swab. Before this operation, the whole intestine of all participants was irrigated and the score of the Boston bowel preparation scale reached 9. The biodiversity of gut microbiome of rectum revealed significant difference between anal fistula patients and healthy individuals. 36 discriminative taxa were identified by LEfSe analysis between two groups. At the phylum level, Synergistetes was enriched in anal fistula patients, while Proteobacteria was higher in healthy individuals. We also found that at the genus level, Blautia, Faecalibacterium, Ruminococcus, Coprococcus, Bacteroides, Clostridium, Megamonas and Anaerotruncus were highly enriched in anal fistula patients, while the microbiome of healthy individuals was enriched with Peptoniphilus and Corynebacterium. Spearman correlations showed the extensive and close association among genera and species. Finally, a diagnostic prediction model was constructed by random forest classifier, and the area under curve (AUC) reached 0.990. This study gave an important hint for analyzing gut microbiome of rectum in anal fistula patient.Keypoints.We use the 16S rRNA gene sequencing to test the microbiome samples extracted from the intestinal swab. This is the first study to explore the gut microbiome of rectum using this workflow. We also found the distinct gut microbiome of rectum differences between anal fistula patients and healthy individuals.

Platelet-rich plasma in the treatment of anal fistula: a systematic review and meta-analysis. Int J Colorectal Dis 2023; 38:70. [PMID: 36905475 DOI: 10.1007/s00384-023-04367-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/05/2023] [Indexed: 03/12/2023]
Abstract
OBJECTIVE To analyse the safety and effectiveness of platelet-rich plasma (PRP) in anal fistula patients. METHODS Online databases including PubMed, Embase, Cochrane Library, and Web of Science were searched from inception to December 5, 2022, for eligible studies about evaluating the efficacy of platelet-rich plasma (PRP) in treating anal fistula. Literature search, screening, data extraction, and quality assessment were carried out by two independent investigators. The overall cure rate, the complete cure rate, the recurrence rate, and the adverse event rate with their 95% confidence intervals (95% CI) were the primary calculation indexes. Subgroup analyses were conducted primarily according to whether PRP was combined with other treatments. Softwares of MedCalc 18.2 and Review Manager 5.3 were used for meta-analysis. RESULTS A total of 14 studies with 514 patients were included in the meta-analysis. The overall cure rate of 14 studies was 72.11% (95% CI 0.64-0.79). The cure rate of PRP alone was 62.39% (95% CI 0.55-0.69). The combined cure rate of PRP with other treatments was 83.12% (95% CI 0.77-0.88). The cure rate of interventions involving PRP were superior to the cure rate of surgery methods without using PRP significantly in the 4 randomized controlled studies (RR = 1.30, 95% CI 1.10-1.54, p = 0.002). The complete cure rate of the 8 studies was 66.37% (95% CI 0.52-0.79). The recurrence rate of the 12 studies was 14.84% (95% CI 0.08-0.24). The adverse event rate of the 12 studies was 6.31% (95% CI 0.02-0.12). CONCLUSION PRP showed favorable safety and effectiveness in the treatment of anal fistula, especially combined with other treatment procedures.

Abstract
BACKGROUND Anal fistula is one of the most common diseases in anorectal surgery. The wound healing after surgery can affect the prognosis of patients. We conducted a protocol for systematic review and meta-analysis to assess the efficacy and safety of Chinese herbal medicine for reducing wound complications after anal fistula surgery. METHODS We have prepared this protocol in accordance with the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA-P) statement. We will search the following databases: the China National Knowledge Infrastructure, Wanfang Database, Chinese Science and Technology Periodical Database, Chinese Biomedical Literature Database, Pubmed, Embase, Web of Science, and the Cochrane library. Two authors will independently assess the risk of bias of the included studies based on the bias risk assessment tool recommended in the Cochrane "Risk of bias" assessment tool. All calculations are carried out with STATA13.0 software. RESULTS A synthesis of current evidence of Chinese herbal medicine for wound management after anal fistula surgery will be shown in this protocol. CONCLUSION This study may provide more convincing evidence to help clinicians make decisions when dealing with anal fistula patients after surgery.

Abstract
OBJECTIVE This study was designed to assess the demographic characteristics of patients with Crohn's perianal fistula (CPF) who were treated at a tertiary referral institution. Surgical outcomes were compared in groups of patients who underwent seton placement, fistulotomy, and stem cell therapy. METHODS Patients who underwent surgery for CPF between 2015 and 2017 at Asan Medical Center, Seoul, Korea, were retrospectively evaluated. Patients were divided into groups who underwent seton placement, fistulotomy, and stem cell therapy. Their clinical variables and closure rates were compared. RESULTS This study included 156 patients who underwent a total of 209 operations. More than half of the operations consisted of seton placement (67%), followed by stem cell therapy (18%) and fistulotomy (15%) patients. Of the 209 fistulas, 153 (73%) were complex, with an overall closure rate of 38% during a median follow-up of 29 months. Closure rates following fistulotomy, stem cell therapy, and seton placement were 90%, 70%, and 18%. Seton placement was more significantly frequently used than the other procedures in patients with complex fistula and those with abscesses. Of the 79 fistulas that achieved complete closure, 11 (14%) recurred. The recurrence rates did not differ among the various techniques. CONCLUSION Surgical treatment of CPF is dependent on lesion type. Seton placement was the primary draining procedure for complex fistulas and abscesses, resulting in low closure rates. Fistulotomy was the definite procedure for low type and simple fistula. Stem cell therapy showed high closure rates as definitive treatment, even for complex fistulas.

Abstract
This study quantifies the damage to the internal anal sphincter (IAS) after a rectal mucosal advancement flap for a high transphincteric fistula in 16 patients using 3D-endoanal ultrasound. This was correlated with postoperative incontinence and quality of life scores. The median length of involved IAS preoperatively was 50 % (20-100) and 93.72 % for EAS (47.4-100 %). IAS division did not influence continence (p > 0.05). Continence deteriorated between the pre-, postoperative (p = 0.014) and six-month follow-up (p = 0.005), with no significant differences after one year (p > 0.05). The FIQOL score and SF-36 deteriorated initially, with recovery in all domains except for mental health after one year. Three fistulas recurred (18.75 %).

Abstract
BACKGROUND Surgery is the most common and effective therapy for anal fistula, while the postoperative complication, such as pain, edema, pruritus, turgescence, and exudation in surgical wound, can have serious impact on wound healing and patients' quality of life. Chinese herbal fumigant and lotion have been commonly used in postoperative treatment and achieved satisfied effect in China. However, clinical evidence-based literature of Chinese herbal fumigant and lotion for postoperative anal fistula is not sufficient. This protocol is described for a systematic review to investigate the beneficial effects. METHODS A systematic search will be conducted in database involving PubMed, the Cochrane library, Embase, Web of Science, Google Scholar, SinoMed, China National Knowledge Infrastructure(CNKI), VIP, Wanfang Database, CiNii(National Institute of Informatics), and KISS(Koreanstudies Information Service System) from inceptions to December 31, 2019. We will include randomized controlled trials (RCT) regarding Chinese herbal fumigant and lotion in the treatment of complication in surgical wound of anal fistula. Quality of included RCTs will be assessed according to the Cochrane Handbook 5.1.0. GRADE will be used to assess the quality of evidence. The summary results will be pooled using the random-effects model or fixed-effects model according to the heterogeneity of included studies. RESULTS After peer-review, the study will be disseminated in scientific journals and conferences. CONCLUSION This systematic review will provide evidence for the efficacy of Chinese herbal fumigant and lotion for curing postoperative complication of anal fistula. In addition, it might provide suggestions for Chinese medicine clinical practice or guideline. PROSPERO REGISTRATION CRD42020164975.

Abstract
BACKGROUND Despite a burgeoning literature during the last two decades regarding perioperative risk management of anal fistula, little is known about its risk factors that influence postoperative recurrence. We performed a meta-analysis to summarize and assess the credibility of evidence of potential risk factors for anal fistula recurrence (AFR) after surgery. METHODS Pubmed and EMBASE without language restriction were searched from inception to April 2018 that reported risk factors which predisposed recurrence after anal fistula surgery. We excluded studies that involved patients with anal fistula associated with Crohn's disease. MOOSE guidelines were followed when this meta-analysis was performed. We used random-effects models to pool relative risks (RRs) with 95% confidence intervals (CIs). Evidence from observational studies was graded into high-quality (Class I), moderate-quality (Class II/III) and low-quality (Class IV) based on Egger's P value, total sample size and between-study heterogeneity. RESULTS Of 3514 citations screened, 20 unique observational studies comprising 6168 patients were involved in data synthesis. High-quality evidence showed that AFR was associated with high transsphincteric fistula (RR, 4.77; 95% CI, 3.83 to 5.95), internal opening unidentified (RR, 8.54; 95% CI, 5.29 to 13.80), and horseshoe extensions (RR, 1.92; 95% CI, 1.43 to 2.59). Moderate-quality evidence suggested an association with prior anal surgery (RR, 1.52; 95% CI, 1.04 to 2.23), seton placement surgery (RR, 2.97; 95% CI, 1.10 to 8.06), and multiple fistula tract (RR, 4.77; 95% CI, 1.46 to 15.51). High-quality evidence demonstrated no significant association with gender or smoking; moderate-quality evidence also suggested no association with age, tertiary referral, alcohol use, diabetes mellitus, obesity, preoperative seton drainage, high internal opening, postoperative drainage, mucosal advancement flap surgery, supralevator extensions, location or type of anal fistula. CONCLUSION Several patient, surgery and fistula-related factors are significantly associated with postoperative AFR. These findings strengthen clinical awareness of early warning to identify patients with high-risk disease recurrence for AFR.

Abstract
Introduction Perianal fistulas are a common problem. Video-assisted anal fistula treatment is a new technique for the management of this difficult condition. We describe our initial experience with the technique to facilitate the treatment of established perianal fistulas. Methods We reviewed a prospectively maintained database relating to consecutive patients undergoing video-assisted anal fistula treatment in a single unit. Results Seventy-eight consecutive patients had their perianal fistulas treated with video-assistance from November 2014 to June 2016. Complete follow-up data were available in 74 patients, with median follow-up of 14 months (interquartile range 7-19 months). There were no complications and all patients were treated as day cases. Most patients had recurrent disease, with 57 (77%) having had previous fistula surgery. At follow-up, 60 (81%) patients reported themselves 'cured' (asymptomatic) including 5 patients with Crohn's disease and one who had undergone 10 previous surgical procedures. Logistical stepwise regression did not demonstrate any statistically significant factors that may have been considered to affect outcome (age, gender, diabetes, previous I&D, Crohn's disease, smoking, type of fistula). Conclusions Our data have shown that video-assisted anal fistula treatment is safe and effective in the management of perianal fistulas in our patients and this suggests it may be applied to all patients regardless of comorbidity, underlying pathology or type of fistula.

Abstract
INTRODUCTION Anal fistula affects people of working age. Symptoms include abscess, pain, discharge of pus and blood. Treatment of this benign disease can affect faecal continence, which may, in turn, impair quality of life (QOL). We assessed the QOL of patients with cryptoglandular anal fistula. METHODS Newly referred patients with anal fistula completed the St Mark's Incontinence Score, which ranges from 0 (perfect continence) to 24 (totally incontinent), and Short form 36 (SF-36) questionnaire at two institutions with an interest in anal fistula. The data were examined to identify factors affecting QOL. RESULTS Data were available for 146 patients (47 women), with a median age of 44 years (range 18-82 years) and a median continence score of 0 (range 0-23). Versus population norms, patients had an overall reduction in QOL. While those with recurrent disease had no difference on continence scores, QOL was worse on two of eight SF-36 domains (p<0.05). Patients with secondary extensions had reduced QOL in two domains (p<0.05), while urgency was associated with reduced QOL on five domains (p<0.05). Patients with loose seton had the same QOL as those without seton. No difference in urgency was found between patients with and without loose seton. In primary fistula patients, 19.4% of patients experienced urgency versus 36.3% of those with recurrent fistulas. CONCLUSIONS Patients with anal fistula had a reduced QOL, which was worse in those with recurrent disease, secondary extensions and urgency. Loose seton had no impact on QOL.

Abstract
OBJECTIVE The history of treatments for fistula-in-ano can be traced back to ancient times. Current treatment of transphincteric fistulae is controversial, with many options available. We reviewed the history of treatment using cutting setons and present our series of transphincteric fistulae in the light of the series in the literature. DESIGN Literature review and case series. SETTING Hospital based coloproctology service PARTICIPANTS 140 consecutive patients presenting with fistula-in-ano were included. MAIN OUTCOME MEASURES The literature pertaining to treatment of transphincteric fistula was reviewed, along with the outcome of various treatment methods for this condition. Data were collected for 140 consecutive patients presenting with fistula- in-ano were assessed for fistula healing, recurrence and complications. RESULTS A total of 140 consecutive patients with fistula-in-ano were identified, of which 111 were cryptoglandular (79.3%). Eighty-one of these 111 were transphincteric (73.0%). At a median follow-up of 35 months (range, 2-83 months), 70 transphincteric fistulae had healed (86.4%), 10 were still undergoing treatment (12.3%) and one patient was lost to follow-up prior to treatment (1.2%). Two patients in this group required a stoma (2.5%), six patients developed recurrence (7.4%); three 'true' recurrences (3.7%). One (1.2%) developed a chronic fissure. There were no reported cases of incontinence. CONCLUSIONS The management of transphincteric fistula-in-ano is complex and controversial, for which no clear surgical procedure has gained acceptance as the gold standard. This study demonstrates that transphincteric fistulae can be successfully treated using cutting setons. A high healing rate (86.4%), low recurrence rate (7.4%) and a low complication rate (3.7%) are shown, which compares favourably with published rates over a long follow-up.

Abstract
BACKGROUND Perianal abscesses and fistulae-in-ano are a common anorectal complaint causing significant distress to patients, and present a considerable treatment challenge. Principal of treatment is achieving closure of the fistula while maintaining continence. There are numerous treatment approaches with large debate about which method is "ideal." Our aim was to assess the tolerance and efficacy of loose seton placement in the treatment for fistula-in-ano. METHODS We performed a retrospective multicenter review of the management of anal fistulae with loose seton placement over a three-year period. All patients underwent a standardized procedure, and were rescheduled for an elective change of seton until fistula resolution. Patients' demographics, medical history, comorbidities, overall number and time interval between seton placements, tolerance, and morbidity of the procedure were recorded. RESULTS A total of 200 consecutive patients had loose seton placement. 69.5 % (n = 139) were males, and mean age was 42.6 years. The median number of setons required for each patient was 3 (range 1-8; mean 2.84). The mean interval between changes was 3.08 months (range 2-4 months). All patients had successful clearance of fistula. The procedure was well tolerated in 96 % of patients (n = 187). Only 1 % (n = 2) could not tolerate the presence of seton due to significant discomfort. Fistula recurrence rate was 6 % (n = 12). CONCLUSIONS Recently, newer treatment modalities have been reported with enthusiasm. However, there remains a lack of strong statistical evidence of efficacy to support their use. Overall, loose seton placement remains a well-tolerated, pragmatic low-cost solution to this common and difficult condition as evident by our study.

Abstract
Minimally invasive anal fistula treatment (MAFT) was introduced to minimize early postoperative morbidity, preserve sphincter continence, and reduce recurrence. We report our early experience with MAFT in 416 patients. Preoperative MRI was performed in 150 patients initially and subsequently thereafter. The technique involves fistuloscope-aided localization of internal fistula opening, examination and fulguration of all fistula tracks, and secure stapled closure of internal fistula opening within anal canal/rectum. MAFT was performed as day-care procedure in 391 patients (93.9 %). During surgery, internal fistula opening could not be located in 100 patients (24 %). Seven patients required readmission to hospital. Mean visual analog scale scores for pain on discharge and at 1 week were 3.1 (1-6) and 1.6 (0-3), respectively. Mean duration for return to normal activity was 3.2 days (2-11 days). Fistula recurrence was observed in 35/134 patients (26.1 %) at 1 year follow-up. MAFT may be performed as day-care procedure with benefits of less pain, absence of perianal wounds, faster recovery, and preservation of sphincter continence. However, long-term results from more centers are needed especially for recurrence.

Hybrid seton for the treatment of high anal fistulas: results of 128 consecutive patients. Tech Coloproctol 2013; 18:187-93.

Abstract
Background The aim of this study was to evaluate our experience in managing high anal fistulas with a simple modification of the cutting seton. Methods We performed a retrospective review of standardized patient charts and of prospectively collected scores and questionnaires. Surgical outcomes of 128 consecutive, well-documented patients with high anal fistulas, including anterior transsphincteric fistulas in females, treated using a hybrid seton, were analyzed. Results No significant complications occurred. The mean postoperative pain scores on a visual analog scale were 3.23 and 0.61, on days 1 and 7, respectively. Complete healing was achieved in 67 cases (52.3 %) at 1 month and in all cases (100 %) at 3 months. Recurrent fistula was noted in 2 patients (1.5 %) at 6 and 12 months. The mean postoperative incontinence scores at 3 and 12 months did not differ significantly from the preoperative score (p = 0.061, Wilcoxon’s test). The depression, life style, and embarrassment item scores of the fecal incontinence quality of life index improved significantly after surgical treatment. Conclusions The results of this series suggest that the hybrid seton might be a valid alternative for the treatment of high anal fistulas, eliminating the need for postoperative adjustments. The slow and stable cutting of the sphincter seems to have a positive effect on the maintenance of continence. The successful outcome is associated with significant improvement in quality of life.

Abstract
AIM: To investigate the efficacy of the anal fistula plug (AFP) compared to the mucosa advancement flap (MAF), considered the best procedure for patients with a complex anal fistula.
METHODS: The literature search included PubMed, EMBASE, Cochrane Library and OVID original studies on the topic of AFP compared to MAF for complex fistula-in-ano that had a deadline for publication by April 2011. Randomized controlled trials, controlled clinical trials and prospective cohort studies were included in the review. After information collection, a meta-analysis was performed using data on overall success rates as well as incidence of incontinence and morbidity. The quality of postoperative life was also included with the clinical results.
RESULTS: Six studies involving 408 patients (AFP = 167, MAF = 241) were included in the meta-analysis. The differences in the overall success rates and incidence of fistula recurrence were not statistically significant between the AFP and MAF [risk difference (RD) = -0.12, 95%CI: -0.39 - 0.14; RD = 0.13; 95%CI: -0.18 - 0.43, respectively]. However, for the AFP, the risk of postoperative impaired continence was lower (RD = -0.08, 95%CI: -0.15 - -0.02) as was the incidence of other complications (RD = -0.06, 95%CI: -0.11 - -0.00). The postoperative quality of life, for patients treated using the AFP was superior to that of the MAF patients. Patients treated with the AFP had less persistent pain of a shorter duration and the healing time of the fistula and hospital stay were also reduced.
CONCLUSION: The AFP is an effective procedure for patients with a complex anal fistula; it has the same success rate but a lower risk of complications than the MAF and may also be associated with an improved postoperative quality of life. Additional evidence is needed to confirm these findings.

Abstract
AIM: To evaluate the efficacy and safety of traditional Chinese surgical treatment for anal fistulae with secondary tracks and abscess.
METHODS: Sixty patients with intersphincteric or transsphincteric anal fistulas with secondary tracks and abscess were randomly divided into study group [suture dragging combined with pad compression (SDPC)] and control group [fistulotomy (FSLT)]. In the SDPC group, the internal opening was excised and incisions at external openings were made for drainage. Silk sutures were put through every two incisions and knotted in loose state. The suture dragging process started from the first day after surgery and the pad compression process started when all sutures were removed as wound tissue became fresh and without discharge. In the FSLT group, the internal opening and all tracts were laid open and cleaned by normal saline postoperatively till all wounds healed. The time of healing, postoperative pain score (visual analogue scale), recurrence rate, patient satisfaction, incontinence evaluation and anorectal manometry before and after the treatment were examined.
RESULTS: There were no significant differences between the two groups regarding age, gender and fistulae type. The time of healing was significantly shorter (24.33 d in SDPC vs 31.57 d in FSLT, P < 0.01) and the patient satisfaction score at 1 mo postoperative follow-up was significantly higher in the SDPC group (4.07 in SDPC vs 3.37 in FSLT, P < 0.05). The mean maximal postoperative pain scores were 5.83 ± 2.5 in SDPC vs 6.37 ± 2.33 in FSLT and the recurrence rates were 3.33 in SDPC vs 0 in FSLT. None of the patients in the two groups experienced liquid and solid fecal incontinence and lifestyle alteration postoperatively. The Wexner score after treatment of intersphincter fistulae were 0.17 ± 0.41 in SDPC vs 0.40 ± 0.89 in FSLT and trans-sphincter fistulae were 0.13 ± 0.45 in SDPC vs 0.56 ± 1.35 in FSLT. The maximal squeeze pressure and resting pressure declined after treatment in both groups. The maximal anal squeeze pressures after treatment were reduced (23.17 ± 3.73 Kpa in SDPC vs 22.74 ± 4.47 Kpa in FSLT) and so did the resting pressures (12.36 ± 2.15 Kpa in SDPC vs 11.71 ± 1.87 Kpa in FSLT), but there were neither significant differences between the two groups and nor significant differences before or after treatment.
CONCLUSION: Traditional Chinese surgical treatment SDPC for anal fistulae with secondary tracks and abscess is safe, effective and less invasive.

Abstract
Background: Treatment of high anal fistulas may be associated with a high risk of continence disorders. Beside traditional procedure of flap-reconstruction the occlusion of the fistula tract using fistula-plugs offers a new sphincter-saving treatment option. In this study for the first time results from Germany are described. Patients and method: 40 patients (30 male, 10 female, age 51±12 years) underwent closure of a high trans-sphincteric (n=28) or supra-sphincteric (n=12) fistula with Gore BioA Fistula Plug® in three surgical departments. The surgical procedures had been performed by five colorectal surgeons. Four patients had Crohn’s disease. Preoperatively 33 patients were completely continent; seven patients complained of minor continence disorders. Treatment of the patients was performed on a intent-to-treat basis and evaluation of the results was retrospective using pooled data from each center. Results: Postoperatively one patient developed an abscess, which had to be managed surgically. In two patients the plug had fallen out within the first two weeks postoperatively. Six months after surgery the fistula has been healed in 20 patients (50.0%). Three additional fistulas healed after 7, 9 rsp. 12 months. The overall healing-rate was 57.5% (23/40). The healing rate differs considerably between the surgeons from 0 to 75% and depends on the number of previous interventions. In patients having only drainage of the abscess success occurred in 63.6% (14/22) whereas in patients after one or more flap fistula reconstruction the healing rate decreased slightly to 50% (9/18). No patient complained about any impairment of his preoperative continence status. Conclusion: By occlusion of high anal fistulas with a plug technique definitive healing could be achieved in nearly every second patients. Previous surgery seems to have a negative impact on success rate. We have not observed any negative impact on anal continence. From that point of view anal fistula plugs might be discussed as a treatment option for high anal fistulas, but further studies are needed to gain conclusive evidence.

Abstract
BACKGROUND Cryptoglandular anal fistula arises in 2 per 10 000 persons per year and is most common in young men. Improper treatment can result in fecal incontinence and thus in impaired quality of life. METHOD This S3 guideline is based on a systematic review of the pertinent literature. RESULTS The level of evidence for treatment is low, because relevant randomized trials are scarce. Anal fistulae are classified according to the relation of the fistula channel to the sphincter. The indication for treatment is established by the clinical history and physical examination. During surgery, the fistula should be probed and/or dyed. Endo-anal ultrasonography and magnetic resonance imaging are of roughly the same diagnostic value and may be useful as additional studies for complex fistulae. Surgical treatment is with one of the following operations: laying open, seton drainage, plastic surgical reconstruction with suturing of the sphincter, and occlusion with biomaterials. Only superficial fistulae should be laid open. The risk of postoperative incontinence is directly related to the thickness of sphincter muscle that is divided. All high anal fistulae should be treated with a sphincter-saving procedure. The various plastic surgical reconstructive procedures all yield roughly the same results. Occlusion with biomaterials yields a lower cure rate. CONCLUSION This is the first German S3 guideline for the treatment of cryptoglandular anal fistula. It includes recommendations for the diagnostic evaluation and treatment of this clinical entity.

Abstract
Previous studies have demonstrated that the division of sphincter muscle in the treatment of anal fistula may precipitate fecal incontinence. Cutting setons may pose a particular risk of unrecoverable injury to the sphincter apparatus. To evaluate if the use of an adjustable cutting seton mitigates this risk, we performed a retrospective review of all patients operated on for anal fistulae in a 10-year period by a single surgeon. Adjustable cutting setons (consisting of heavy silk ligature with patient-controllable tension) were used selectively. Forty-seven patients met the study criteria. Ninety-four per cent of the fistulae treated were transsphincteric. All of the fistulae were treated with at least partial fistulotomy. Ninety-nine per cent of patients were followed to completion of treatment. One (2%) patient subsequently developed fecal incontinence, and four (9%) developed a recurrent or persistent fistula in the same location. Adjustable cutting setons have been used in our practice with a high success rate and low risk of complications. Our data support adjustable cutting setons as a useful tool in the surgeon's repertoire for treating fistulae that involve the anal sphincter complex.

Abstract
At present, the treatments for complex anal fistula are often associated with high recurrence and insufficient protection of anal function. Fistulotomy and cutting seton often lead to damage to the anal sphincters, increasing the risk of incontinence. Recently, they have been replaced gradually by sphincter-saving measures, such as advancement flap, anal fistula plug and ligation of intersphincteric fistula tract. In this article, we will review the recent advances in sphincter-saving surgical treatment of complex anal fistula.

Abstract
AIM We introduced a modification of the loose seton for high transsphincteric fistula which involved daily self-rotation of the seton by 360°, which we call the progressive migration technique. The outcomes were evaluated. METHOD A retrospective review was undertaken of all operations for anal fistula performed by a single colorectal surgeon from Jan. 2002-Dec. 2007. Twenty-four patients with high transsphincteric fistulas were treated with loose, 0-silk setons. Patients were asked to rotate the seton daily, one revolution in each direction, pulling the knot through the fistula tract. Follow-up was done by phone with questionnaires to address incontinence pain scores, satisfaction, and recurrence. RESULTS The patients' mean age was 48 years (range, 22-77 years), with M/F ratio of 3:1. The mean duration for seton in place was 14 months (range, 2-40 months). Follow-up ranged from 12-81 months (mean, 45 months). The progressive migration technique resulted in the gradual healing of the fistula tract in 75% of patients (n = 18), with no recurrence (setons completely worked their way to the surface [n = 9], or tract migration was extensive to allow a safe completion fistulotomy [n = 9]). All were fistula free. Twenty-five percent (n = 6) had Crohn's disease. Reported incontinence rates were 0% for solid and liquid stool and 8% (n = 2) for flatus. Twenty-five percent (n = 6) tolerated the setons poorly, and an alternative procedure was performed. CONCLUSIONS Simple daily self-rotation of a heavy silk seton, resulting in progressive migration of the fistula tract, is an alternative technique for treating complex, high transsphincteric anal fistulas.

Abstract
AIM Fibrin glue and porcine intestinal submucosa are used in novel sphincter-preserving techniques to heal anal fistulae. However, their success is highly variable and decreases with the length of follow up. The aim of this study was to assess the safety, feasibility and potential efficacy of another novel agent, cross-linked collagen, in two different physical formats, to heal anal fistulae. METHOD Prospectively recruited patients underwent symptom, continence and anal physiology assessments and magnetic resonance imaging. Patients with secondary tracts or acute sepsis were excluded. At operation, participants were randomized to receiving a solid collagen implant or collagen fibres suspended in fibrin glue. Follow up included repeat symptom, continence and physiological assessments at 3 months, and regular clinical review thereafter. RESULTS Twenty-nine of 43 entrants were eligible for inclusion. Thirteen patients received the collagen implant, and 16 collagen-fibrin glue. Three months postoperation, no patient experienced acute sepsis or continence disturbance, and sphincter function and integrity were unchanged. At 29 months, 12 of 15 (one lost to follow up) patients treated with collagen-fibrin glue were healed, compared with seven of 13 who received the implant. CONCLUSION In the short-to-medium term, both techniques are safe and equally effective. The results justify continued research into the use of biomaterials to heal anal fistulae.

Abstract
CONTEXT Management of complex anal fistulas is associated with the risk of sphincter injury and fecal incontinence. In recent years, fibrin glue has emerged as an alternative sphincter-preserving treatment for anal fistulas. To date, however, there is no consensus about the efficacy of the method. OBJECTIVE To specifically evaluate the fibrin glue injection in the management of complex cryptoglandular anal fistulas. METHODS We studied a series of patients with complex anal fistulas treated with fibrin glue between January 2005 and January 2007. Only patients with fistulas of cryptoglandular origin were analyzed. Patients with fistulas related to Crohn's disease, HIV or previous surgery were excluded from the study. Under spinal anesthesia, the fistulas were curetted and injected with fibrin glue. After treatment, patients were followed-up for 12 months. RESULTS Thirty-two patients were enrolled in the study. Two patients were lost to follow-up and were excluded. Out of the remaining 30 patients, only three healed successfully (10%). Among the 27 patients who failed to heal, 9 (33.3%) were diagnosed within the first postoperative month. In 13 patients (48.1%) the failure of treatment occurred in the period between 1 and 3 months, in 3 patients (11.1%) between 3 and 6 months, and in 2 patients (7.4%) between 6 and 9 months after surgery. No treatment-related complications were observed. CONCLUSIONS In this series, fibrin glue treatment for complex cryptoglandular anal fistulas achieved a very low healing rate. Our results do not support the use of fibrin glue as a first-line treatment for patients with this type of fistula.

Abstract
OBJECTIVE The challenge of surgery for anal fistula is to eradicate the fistula track while maintaining anal continence. Seton placement is recommended to reduce postoperative faecal incontinence but interestingly a great range of functional impairment after surgery has been published. The aim of this study was to analyse the influence of intra-operative internal anal sphincter division during tight or cutting seton technique for cryptogenic anal fistula, on the results of recurrence and postoperative faecal incontinence. METHOD A systematic literature review was performed to identify published series from 1966 to May 2007 of patients with anal fistula treated by a tight or cutting seton technique. The published series has been divided in to those where preservation of internal anal sphincter was performed (PIAS group) or where intra-operative surgical division was undertaken in the time of seton placement (SIAS group) .The main endpoints of the review were to study anal fistula recurrence rate and postoperative faecal incontinence. RESULTS Eighteen studies including 19 series and 448 patients were analysed in detail. Recurrence rate was 5.0% and 3.0% in PIAS and SIAS group respectively. Overall faecal incontinence rate was 5.6% in PIAS group and 25.2% in SIAS group. CONCLUSION Although based on low-evidence studies, intra-operative preservation of internal anal sphincter at the time of seton insertion for anal fistula seems to reduce the postoperative faecal incontinence without a substantial increase in recurrence rates.

Abstract
PURPOSE The purpose of this study was to assess the influence of identification of the location of the internal opening of anal fistula on the recurrence rate after surgical treatment in patients with primary transsphincteric anal fistulas. The influence of preoperative rectal ultrasound on the treatment results was studied. METHODS One hundred thirty-one patients operated in the period February 1992 to July 2005 were analyzed. Endorectal ultrasound (ERUS) was not performed (till February 2004) on 103 out of the 131 patients, while the other 28 received ERUS (from March 2004). We performed either cutting seton technique or fistulectomy according to the course of fistulous tract (high or low transsphincteric fistulas). The recurrence rate of anal fistula was assessed after the complete healing of the anal fistula after 6 months. RESULTS In patients in whom ERUS was not performed, the internal opening was identified by endoscopy in 41.7% and in 47.6% intraoperatively. In patients in whom ERUS was preoperatively performed, the internal opening was identified in 85.8%. In all the studied groups, the internal opening of anal fistula was not localized in 13 patients (9.9%). Recurrence of the fistulas occurred in ten patients (7.6%); in seven out of 13 patients, the internal opening was not found (53.85%), and in three out of 118, the internal opening was identified (2.54%). CONCLUSIONS Relative risk of anal fistula recurrence was 20-fold higher in patients in whom the internal opening was not identified than in those with the internal opening identified. Preoperative ERUS doubled the identification rate and thus decreased the risk of recurrence.

Abstract
OBJECTIVE To determine the incidence of anal incontinence after the use of cutting seton treatment for anal fistula. METHOD Literature searches were performed on PubMed, MEDLINE and Google Scholar using the words 'cutting seton(s)', 'seton(s)' and 'anal fistula'. An analysis of the data in the collected references was performed. RESULTS The average rate of incontinence following cutting seton use was 12%. The rate of incontinence increased as the location of the internal opening of the fistula moved more proximally. In the studies that described the types of incontinence, liquid stool was the most common followed closely by flatus incontinence. Incontinence associated with the treatment of fistulas defined as nonspecific cryptoglandular in nature was 18%. CONCLUSION The high incontinence rates that result from the use of cutting setons suggest that this commonly used therapy can damage the continence musculature. Other techniques that do not involve cutting the sphincter, when available, should be preferred, especially for higher fistulas.

Abstract
OBJECTIVE The aim of this study was to determine the efficacy of the anal fistula plug in the treatment of high fistula-in-ano. METHOD Twenty-three patients with high cryptoglandular fistula-in-ano were prospectively studied over 1 year. The number of tracks, number of previous procedures and co-morbid conditions that could potentially affect outcome were noted. A seton was used to guide the AFP into the fistula track which was anchored at the primary opening. RESULTS Two patients were lost to follow-up. Twenty-one patients (mean age was 49.8 years) were followed from 192 to 543 days (median = 292 days). Thirteen patients had single track, eight had multiple tracks and 14 had a recurrent fistula. Success, defined by closure of all fistula tracks occurred in 71.4% (15/21). The success rate was 84.6% in patients with a single fistula track (11/13) compared with 50% in patients with multiple tracks (4/8) (P = 0.14, Fisher's exact test). Recurrent [10/14 (71.4%)] vs nonrecurrent fistulae [5/7 (71.4%)] had no bearing on the outcome (P = 1.0). Two patients experienced healing despite extrusion of the plug in the early postoperative period. The procedure was safe and well tolerated. CONCLUSION The Surgisis AFP was successful in 71.4% of patients. Plug extrusion does not necessarily mean failure.

Abstract
BACKGROUNDS AND AIM Endorectal advancement flap repair is a well-recognized method for the treatment of complex anorectal fistula. The purpose of this study was to prospectively assess the clinical and functional results of endorectal advancement flaps for complex anorectal fistula and to identify factors that affect outcome. MATERIALS AND METHODS A prospective study of 56 patients was performed. Clinical and functional results were studied using the Wexner continence scale and anal manometry before and after surgery. Factors associated with recurrence and incontinence were analyzed by univariate and multivariate regression analysis. RESULTS Sixty endorectal flaps were constructed in 56 patients. Mean age was 49 years (range 24-74). The fistula was of cryptoglandular origin in 91.1% cases. Mean follow-up was 43.8 months. The technique was repeated in four patients because of recurrence (7.1%), with subsequent healing in all cases. There were significant reductions in maximum resting pressure 3 months after surgery (83.6+/-33.2 vs 45.6+/-18.3, p<0.001) and maximum squeeze pressure (208.8+/-91.5 vs 169.5+/-75, p<0.001). Before surgery, five patients (8.9%) reported incontinence symptoms. After surgery, 78.6% patients had normal continence, seven patients (12.5%) complained of minor incontinence, and five (9%) had major continence disturbances. None of the variables studied (age, sex, previous fistula surgery, rectovaginal fistula, and Crohn's disease) affected the outcome of the procedure in multivariate analysis. CONCLUSIONS Endorectal advancement flap repair is an effective technique for complex anal fistula, with a low recurrence rate (7.1%). Patients (21.4%) reported disturbed anal continence. It is still not possible to identify factors that are predictive of failure or incontinence.

Abstract
OBJECTIVE The aim of this paper was to analyse the results of treatment of anal fistulas retrospectively. METHODS Between 1992 and 2004, 407 patients were operated on for perianal fistula. In the follow-up period, 107 patients were lost, so 300 patients were analysed in the study. The mean follow-up time was 4.2 years. Analysed parameters included: types of surgical procedures in different kinds of fistulas and postoperative complications. Various types of surgical procedures and their effectiveness were described. Late results were assessed taking into account healing time, duration of sick leave, recurrence rate and incidence of anal sphincter dysfunction. Severity of gas and stool incontinence was assessed according to the Cleveland Clinic Incontinence Score. RESULTS In our study, subcutaneous fistula was diagnosed in 23.3%, inter-sphincteric in 18%, trans-sphincteric in 37.7%, supra-sphincteric in 16% and extra-sphincteric in 5% of patients. Single-tract fistulas were present in 88.7% and multi-tract fistulas were present in 11.3%. Overall, 242 patients had primary fistulas and 58 patients had recurrent fistulas. The most frequently performed procedures were cutting seton (139 patients) and radical fistulectomy (104 patients). Recurrent fistulas developed in 14.3%. Postoperative gas and/or stool incontinence was noticed in 10.7%. The recurrence rate was 5.4% in patients with primary fistula and in 51.7% patients presenting with a recurrent fistula. Gas and stool incontinence developed in 3.7% of patients with primary fistulas and in 39.7% of patients presenting with recurrent fistulas. Recurrence rate was 12% in the patients of single-tract fistulas and 32.4% in the patients of multi-tract fistulas. Postoperative gas and/or stool incontinence occurred in 8.3% of patients of single-tract fistulas and in 29.4% of patients of multi-tract fistulas. CONCLUSIONS The complication rate was 10-fold higher in patients presenting with a recurrent fistula than in those with primary fistulas and threefold higher in patients with multi-tract fistulas than in those with single-tract fistulas.

Abstract
OBJECTIVE To assess the short and intermediate outcomes of a modification of the traditional cutting seton technique, using a 'snug' silastic seton, to treat idiopathic anal fistulae. PATIENTS AND METHODS Between August 1997 and December 2002, 35 patients with idiopathic fistulae (4 female; age 26-76 years) underwent insertion of a 'snugly' tied 1 mm silastic seton (silicone nerve vessel retractor, Medasil), as definitive treatment. Short-term assessment was performed by case note review. Patients were subsequently invited to participate in a medium-term review. RESULTS Twenty-nine patients' notes (3 female) were available for short-term analysis. Fistulae were classified as intersphincteric (9) and transsphincteric (20). The seton spontaneously cut out in 15/29 (52%) after a median of 24 weeks. In 14 patients the seton enclosed residual tissue (< 5 mm) required division as a day case procedure, at a median of 35 weeks. All fistulae healed but 10/29 (34%) patients (1 female; 8 transsphincteric) experienced minor incontinence. Sixteen patients participated in a medium-term review at a median of 42 months; 7 had experienced early continence disturbance. No patient suffered recurrence, but minor incontinence persisted in 4/16 (25%) patients (0 females; 3 transsphincteric). All patients were at least 'satisfied' with the outcome. CONCLUSION In the short and medium term, the 'snug' seton is a safe and effective addition to the fistula surgeon's armamentarium.

Abstract
Anal fistula is a frequent condition. The most commonly accepted origin is infectious. The most widely used classification is based on cryptoglandular theory and on the position of the fistulous tract in relation to the anal sphincter. Physical examination will help to identify the type of fistula and allow its treatment to be planned. The most widely used complementary tests are endoanal ultrasound and magnetic resonance imaging. We review the various therapeutic options and their results, especially fistulotomy, endorectal advancement flap, use of sedal, anodermal advancement flap, sphincterorrhaphy with sphincter repair, and fibrin glue.

Abstract
OBJECTIVE After sphincter-sparing core fistulectomy for deep anal fistula most surgeons advance a rectal mucosal flap to reinforce closure of the internal opening. Our own method having for many years been simple appositional closure the resulting series presented an opportunity for comparison. PATIENTS AND METHODS From November 1987 to January 2001, 44 patients underwent 46 core fistulectomies with flap-less direct appositional closure in our unit. Records were kept prospectively. Twenty-six fistulae (in 28 patients) appeared healed at two to five months follow-up and the patients had been discharged. A full review was mounted in May 2001, when 16 of the healed patients could be contacted and questionnaires completed. Two patients were excluded from the study. RESULTS The procedure failed in 16 patients initially and was found to have done so in two more at long-term follow-up (41% overall). Three patients had died and five could not be traced. CONCLUSION Simple appositional closure after core fistulectomy for deep anal fistula seems inferior to methods using flap reinforcement.

Abstract
OBJECTIVE To study the accuracy of endoanal ultrasound in pre-operative assessment of cryptoglandular anal fistulas, with respect to the site of the internal opening, type and depth of the fistula tract. PATIENTS AND METHODS A consecutive series of 151 patients with anal sepsis underwent pre-operative endoanal ultrasound assessment of a suspected anal fistula. Hydrogen peroxide was used to define the tract when there was doubt as to the course of the fistula. All patients subsequently had surgical exploration under anaesthesia, irrespective of findings at sonography. The site of the internal opening, depth and type of fistula were recorded at surgery, and concordance with the ultrasound was assessed. RESULTS One hundred and forty-five patients were subsequently shown to have a fistula at surgical exploration. Type of fistula: Two thirds were transsphincteric (63%) and one third were inter sphincteric (32%), with a few submucosal, and supra sphincteric fistulas. Ultrasound correctly predicted surgical findings in 82% of patients (124/151). Concordance was highest for transsphincteric fistulas (87%). Internal opening: Accuracy of predicting the site of the internal opening was 93% (140/151). The commonest site for the internal opening was the midline posteriorly (49%), followed by the midline anteriorly (25%), the rest lay laterally. Fistula depth: Ultrasound and surgical assessment of the depth of fistulas was concordant in 120 of 145 patients (83%). CONCLUSIONS Endoanal ultrasound has a high accuracy of predicting the site of internal opening of an anal fistula. Endoanal ultrasound is able to assess the type and depth of a fistula. This information is useful for pre-operative planning of fistula treatment.
