Abstract
BACKGROUND Crohn's anal fistula is a challenging condition, and may require multiple surgical procedures. To replicate successful procedures, these must be adequately reported in the literature. The aim of this study was to review the quality of reporting of components of surgical interventions for Crohn's anal fistula. METHODS A systematic review was conducted. It was registered with PROSPERO (CRD:42019135157). The Medline and EMBASE databases were searched for studies reporting interventions intended to close fistula in patients with Crohn's disease, published between 1999 and August 2019. Abstracts and full texts were screened for inclusion by two reviewers. Dual extraction of data was performed to compare reporting to the TIDiER and Blencowe frameworks for reporting of interventions. RESULTS Initial searches identified 207 unique studies; 38 full texts were screened for inclusion and 33 were included. The most common study design was retrospective cohort (17/33), and the most frequently reported interventions were anal fistula plug (n = 8) and fibrin glue (n = 6). No studies showed coverage of all domains of TIDieR. Reporting was poor among domains related to who provided an intervention, where it was provided, and how it was tailored. Reporting of domains in the Blencowe framework was poor; the majority of studies did not report the component steps of procedures or efforts to standardise them. CONCLUSIONS This study demonstrates that reporting on technical aspects of interventions for Crohn's anal fistula is poor. Surgeons should aim to improve reporting to allow accurate reproduction of techniques both in clinical practice and in clinical trials.

Abstract
Perianal diseases, common complications of Crohn's disease, are difficult to diagnose/manage. Patients with perianal Crohn's disease suffer from persistent pain and drainage, recurrent perianal sepsis, impaired quality of life, and financial burden. Conventional medical and surgical therapies carry risk of infection, myelosuppression, incontinence, disease recurrence. Although the phenotype of Crohn's disease has been extensively studied, reported outcomes are inconsistent. Endoanal ultrasonography is also becoming popular because of low cost and ability to acquire images in real time. Emerging management strategies for treatment including laser therapy, local injection of agents, use of hyperbaric oxygen, and stem cell therapy, have demonstrated efficacy.

Abstract
BACKGROUND The ligation of the inter-sphincteric fistula tract plus bioprosthetic anal fistula plug (LIFT-plug) is a new procedure in the treatment of trans-sphincteric perianal fistulas. The aim of this study was to evaluate its long-term outcomes. MATERIAL AND METHODS Clinical data of 78 patients with trans-sphincteric perianal fistula who were managed by the LIFT-plug technique between March 2014 to October 2016 were analyzed retrospectively. The operation time, healing rate, postoperative complications, recurrences, and length of stay were reviewed. RESULTS No serious complications occurred during the operation in all patients. The median follow-up was 30 months (16 to 47 months), clinical healing of the anal fistula occurred in 75 patients (96.2%). The median operative time was 25 minutes (18 to 45 minutes). The mean complete healing time was 16 days (9 to 46 days). The median healing time for the external anal fistula opening was 2 weeks (range, 2 to 3 weeks), and the inter-sphincteric groove incision healing time was 4 weeks (range, 3 to 7 weeks). The median hospital stay after operation was 5 days. Fistula recurred in 2 patients because of spontaneous expulsion of the plug at 7 days post-surgery; perianal abscess occurred in 1 patient. The anal function was evaluated in 70 patients of the 78 patients. Perfect control of continence was recorded for 97.1% of the patients (68 out of 70 patients). Two patients were identified to a rare complication of gas incontinence (Wexner score 1). CONCLUSIONS LIFT-plug procedure for the treatment of trans-sphincteric fistulas is a simple procedure with a high healing rate, minimal invasiveness, quick healing, and without disturbance to anal function. LIFT-plug is an ideal procedure for trans-sphincteric fistula.

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

[PMID: 29732218 PMCID: PMC5926628 DOI: 10.5173/ceju.2018.1353] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Revised: 09/16/2017] [Accepted: 11/13/2017] [Indexed: 11/22/2022] Open
Abstract
Introduction Recto-urethral fistula (RUF) is a relatively rare surgical condition, the treatment of which is quite challenging. There are many causes of RUF, but 60% of them are iatrogenic following open prostatectomies, radiotherapy, brachytherapy, urethral instrumentation etc. We present a series of six cases treated at our institution. Material and methods A retrospective study of all six patients with recto-urethral fistula treated at our centre between 2011 and 2016 was performed. The study included charting of information like age, etiology, clinical presentation, diagnostic modalities, treatment protocols, complications and recurrence. All the patients had simple direct fistulas with no previous history of repair. One patient had history of pelvic fracture following road traffic accident, one patient had a penetrating perineal injury following road traffic accident; two patients had history of Freyer's prostatectomy for benign prostatic hypertrophy; two patients had history of open radical prostatectomy performed at other centres. All patients were treated with an initial double diversion (suprapubic cystostomy and colostomy) followed by definitive surgical repair three months later. The surgical technique used was fistula excision, urethral augmentation by buccal mucosal graft, primary rectal defect repair and gracilis muscle flap interposition between the rectum and urethra. Results The patients were followed up ranging from after 6 to 48 months with a mean follow-up period of 27 months. There were minimal complications such as main wound site infections, seroma at the harvested site of gracilis muscle flap, urethral stricture. There was no report of recurrence. Conclusions From our experience, we conclude that this method of repair is a very efficient one without any recurrence and with minimal complications. The results were on par with all the other successful methods of recto-urethral fistula repair described in the literature.

Abstract
Background Anal fistula occurs in approximately one in three patients with Crohn's disease and is typically managed through a multimodal approach. The optimal surgical therapy is not yet clear. The aim of this systematic review was to identify and assess the literature on surgical treatments of Crohn's anal fistula. Methods A systematic review was conducted that analysed studies relating to surgical treatment of Crohn's anal fistula published on MEDLINE, Embase and Cochrane databases between January 1995 and March 2016. Studies reporting specific outcomes of patients treated for Crohn's anal fistula were included. The primary outcome was fistula healing rate. Bias was assessed using the Cochrane ROBINS‐I and ROB tool as appropriate. Results A total of 1628 citations were reviewed. Sixty‐three studies comprising 1584 patients were ultimately selected in the analyses. There was extensive reporting on the use of setons, advancement flaps and fistula plugs. Randomized trials were available only for stem cells and fistula plugs. There was inconsistency in outcome measures across studies, and a high degree of bias was noted. Conclusion Data describing surgical intervention for Crohn's anal fistula are heterogeneous with a high degree of bias. There is a clear need for standardization of outcomes and description of study cohorts for better understanding of treatment options.

Abstract
Despite advances in surgical technique, postoperative complications may lead to refractory cutaneous sinus tracts or tunnels. Negative pressure wound therapy is difficult to apply in longer tracts with a narrow diameter opening and conservative treatment failures ultimately necessitate surgical revisions. The aim of this pilot study was a clinical utility assessment of two different commercial placental membrane products for refractory cutaneous sinus tracts of surgical origin. Patients were treated with viable cryopreserved placental membrane (vCPM, n = 6) or devitalized dehydrated amnion/chorion membrane (dHACM, n = 6). The primary outcome measurement was the proportion of complete sinus tract depth resolution without exudate. Secondary endpoints included 4-week percent reduction in sinus tract probing depth and peri-tract wound surface area, days and number of grafts to resolution, number of wound-related infections, and 1-year recurrence rate for closed sinus tracts. All vCPM patients demonstrated complete sinus tract resolution compared to zero closures in the dHACM group (p = 0.00216). The vCPM group achieved greater percent reduction in probing depth (73.3 ± 21.9 versus −4.4 ± 91.3) and surrounding wound surface area (34.8 ± 86.8 versus −279.3 ± 454.9) at 4 weeks than dHACM. The use of viable intact cryopreserved placental membrane has demonstrated positive clinical outcomes for the treatment for refractory exudative sinus tracts and may be an alternative to repeat surgical intervention.

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

Abstract
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
Fistulas are a frequent manifestation of Crohn's disease (CD) and can result in considerable morbidity. Approximately 35% of all patients with CD will experience one fistula episode during their disease course of which 54% is perianal. The major symptoms of patients with perianal fistulas are constant anal pain, the formation of painful swellings around the anus and continuous discharge of pus and/or blood from the external fistula opening. The exact aetiology of perianal fistulas in CD patients remains unclear, but it is thought that a penetrating ulcer in the rectal mucosa caused by active CD forms an abnormal passage between the epithelial lining of the rectum and the perianal skin. Genetic, microbiological and immunological factors seem to play important roles in this process. Although the incidence of perianal fistulas in patients with CD is quite high, an effective treatment is not yet discovered. In this review all available medical and surgical therapies are discussed and new treatment options and research targets will be highlighted.

Abstract
Crohn disease involves the perineum and rectum in approximately one-third of patients. Symptoms can range from mild, including skin tags and hemorrhoids, to unremitting and severe, requiring a proctectomy in a small, but significant, portion. Fistula-in-ano and perineal sepsis are the most frequent manifestation seen on presentation. Careful diagnosis, including magnetic resonance imaging or endorectal ultrasound with examination under anesthesia and aggressive medical management, usually with a tumor necrosis factor-alpha, is critical to success. Several options for definitive surgical repair are discussed, including fistulotomy, fibrin glue, anal fistula plug, endorectal advancement flap, and ligation of intersphincteric fistula tract procedure. All suffer from decreased efficacy in patients with Crohn disease. In the presence of active proctitis or perineal disease, no surgical therapy other than drainage of abscesses and loose seton placement is recommended, as iatrogenic injury and poor wound healing are common in that scenario.

Abstract
AIM The aim of this study was to assess the outcome of fibrin glue in high and low anal fistulas. METHODS A prospective, non-randomized trial was carried out on 30 patients who were diagnosed to have fistulas in ano. They were evaluated by categorizing them into high (with the internal opening above the anorectal ring)(14/30) and low anal fistulas (with the internal opening below the anorectal ring)(16/30). The fibrin glue was instilled in their anal tracts. The character of the anal tract, whether it was single or multiple and primary or recurrent, was analyzed. The outcome in terms of a postoperative discharge (failure), the incidence of a postoperative perianal pain/abscess and the glue reaction, was noted at 1 week, 1 month, 3 months and 6 months. A success was defined as the absence of any discharge at 6 months. RESULTS Fourteen patients with high anal fistulas and 16 with low anal fistulas (with a mean age of 48.5yrs) were treated with fibrin glue. 19 patients had primary tracts (7- high group and 12- low group) and 11 had recurrent tracts (7- high group and 4- low group). 20 fistulas were single tracted (8- high and 12- low) and ten were multiple tracted (6- high and 4-low). The success rate at 6 months was 57.14% in the high group and it was 81.25% in the low group. The failure rate was 85.71% in the recurrent high fistula group as compared to 25% in the recurrent low fistula group (p=0.049). 25% of the single tracted high fistulas failed to heal as compared to a 100% healing rate in the single low fistulas group (p=0.90). CONCLUSION This procedure is thus, superior to the conventional surgical treatment, in terms of the patient comfort, an undisturbed sphincter function, a reduced overall hospital stay, wound pain and the complications and adverse reactions. It showed the best results in the primary, single tracted and the low anal fistulas.

Abstract
PURPOSE Our aim is to determine the feasibility and safety of N Butyl Cyanoacrylate (HISTOACRYL), adhesive material in the treatment of fistula in-ano in infants and children. PATIENTS AND METHODS 30 patients who presented with a perianal fistula (25 males and 5 females) were studied. Their ages ranged from 9 months to 15 years. All patients received medical (conservative) treatment. Six patients improved, 7 patients were subjected to surgical intervention, and the remaining 17 patients were managed by injection of adhesive material through the fistula under fluoroscopic guidance and general anesthesia after failure of medical management. RESULTS Of the 17 children who underwent injection therapy to the fistula in-ano after failed medical management, 14 patients were males. The procedure time was 10 to 15 min. The mean follow up was 18 months. Two patients had a recurrence after one to two months. They were subjected to reinjection, and one of them had a second recurrence. Overall, 16 (94%) of 17 patients have had successful closure of their fistula, and one of them healed from a second injection. CONCLUSION Our method of tissue adhesive Cyanoacrylate injection is safe, feasible, and can be used repeatedly in treatment of fistula in-ano in infants and children.

Abstract
The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.

Abstract
AIM The long-term recurrence rate of fibrin glue treatment was analysed in patients with trans-sphincteric cryptoglandular fistula operated by a two-phase procedure: (i) fistulectomy with seton placement; (ii) fibrin sealant (Tissucol Duo®, Baxter) insertion in the track. METHOD Clinical data were collected prospectively for all patients operated between 2004 and 2010. The statistical association of clinical variables and recurrence was analysed and a disease-free curve was constructed using the Kaplan-Meier method. RESULTS Twenty-eight consecutive patients (mean age 48.3 ± 13.3 years; 22 men) were enrolled in the study. Middle and high trans-sphincteric fistulae were diagnosed in 20 (71.4%) and eight (28.6%) patients. Seven (25%) had secondary track formation. The mean interval between the first operation and the fibrin sealant treatment was 12.5 ± 7.6 months. There were no complications related to the procedure. Nine (32.1%, 95% CI 17.9-50.7%) patients developed recurrence between 3 and 27 months after fibrin sealant treatment. Disease-free curves showed that the highest probability of recurrence occurred in the first 2 years. No incontinence was found at a mean follow-up of 20.6 (3-60) months among the 67.8% patients with no evidence of recurrence. CONCLUSION Fibrin sealant is safe and simple. The healing rate is satisfactory without the risk of incontinence.

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
Purpose This prospective study was done to analyze the efficacy of commercial fibrin glue application in the healing of patients with fistulas-in-ano from a long-term (mean 4.5 years) research period. Methods This clinical trial of forty-six patients was performed during the period from January 2004 to February 2005. Thirty-nine men and seven women were treated for a fistula-in-ano with a commercial fibrin glue application. In the operating room, the patients underwent an anorectal examination under spinal anesthesia. The external and internal fistula tract openings were then identified. The fistula tract was curetted. Fibrin glue was injected into the external fistula opening until the fibrin glue could be seen coming from the internal opening. Results The overall initial success rate was 86.95% (40/46). Recurrence rate was 41.30% (19/46). Two patients underwent a re-application with fibrin glue and the fistulas of these patients closed. The total recurrence rate was 36.95% (17/46). The long-term overall success rate was 63.04% (29/46). Conclusion Fibrin glue application was thus found to be an easy, safe, acceptable, successful alternative treatment in the management of fistulas-in-ano. Choosing the patient correctly is very important because long (more than 4 cm) and non-ramificate fistula tracts usually close with commercial fibrin glue.

Abstract
Although rectourinary fistula (RUF) after radical prostatectomy (RP) is rare, it is an important issue impairing the quality of life of patients. If the RUF does not spontaneously close after colostomy, surgical closure should be considered. However, there is no standard approach and no consensus in the literature. A National Center for Biotechnology Information (NVBI) PubMed search for relevant articles published between 1995 and December 2010 was performed using the medical subject headings “radical prostatectomy” and “fistula.” Articles relevant to the treatment of RUF were retained. RUF developed in 0.6% to 9% of patients after RP. Most cases required colostomy, but more than 50% of them needed surgical fistula closure thereafter. The York-Mason technique is the most common approach, and closure using a broad-based flap of rectal mucosa is recommended after excision of the RUF. New techniques using a sealant or glue are developing, but further successful reports are needed.

Abstract
Rectourethral fistulas in adults is a rare but potentially devastating postoperative condition requiring complex and demanding surgery. Fibrin glue treatment has been used with some success in anal and rectovaginal fistulas, and in the case we present here this indication has been extended to a postoperative rectourethral fistula following radical prostatectomy. For the first time, to our knowledge, a fibrin sealant (Quixil) was injected into the fistula tract, and a rectal mucosal flap was used to close the internal opening. The fistula healed in few weeks, and the patient is symptom free after 1 year of follow-up.

Abstract
BACKGROUND & AIMS Fibrin glue is a therapeutic for fistulas that activates thrombin to form a fibrin clot, which mechanically seals the fistula tract. We assessed the efficacy and safety of a heterologous fibrin glue that was injected into the fistula tracts of patients with Crohn's disease (ClinicalTrials.gov No. NCT00723047). METHODS This multicenter, open-label, randomized controlled trial included patients with a Crohn's disease activity index < or =250 and fistulas between the anus (or low rectum) and perineum, vulva, or vagina, that drained for more than 2 months. Magnetic resonance imaging or endosonography was performed to assess fistula tracts and the absence of abscesses. Patients were stratified into groups with simple or complex fistulas and randomly assigned to receive fibrin glue injections (n = 36) or only observation (n = 41) after removal of setons. The primary end point was clinical remission at week 8, defined as the absence of draining, perianal pain, or abscesses. At week 8, a fibrin glue injection was offered to patients who were not in remission. RESULTS Clinical remission was observed in 13 of the 34 patients (38%) of the fibrin glue group compared with 6 of the 37 (16%) in the observation group; these findings demonstrate the benefit of fibrin glue (odds ratio, 3.2; 95% confidence interval: 1.1-9.8; P = .04). The benefit seemed to be greater in patients with simple fistulas. Four patients in the fibrin glue group and 6 in the observation group had adverse events. CONCLUSIONS Fibrin glue injection is a simple, effective, and well-tolerated therapeutic option for patients with Crohn's disease and perianal fistula tracts.

Abstract
BACKGROUND Surgery for anorectal fistula may result in recurrence, or impairment of continence. The ideal treatment for anorectal fistulae should be associated with low recurrence rates, minimal incontinence and good quality of life. OBJECTIVES To assess the efficacy and morbidity of operative procedures for chronic anal fistula, primary outcomes being recurrence and incontinence. SEARCH STRATEGY The following databases were searched: EMBASE (Webspirs 5.1, Silver Platter version 2.0, 1950-2009); Medline (Webspirs 5.1, Silver Platter version 2.0, 1950-2009); The Cochrane Central Register of Controlled Trials (2009 issue 4)and the IndMed ( Indian Medline, www.indmed.nic.in) database. We restricted our search to the English literature. The Indian Journal of Surgery was electronically searched (issues between 2003 and vol 71, Oct 2009). We also searched all primary trial registers (Indian, Australian, Chinese, WHO, ISRCTN and American). SELECTION CRITERIA Randomised controlled trials comparing operative procedures for anorectal fistulae were considered. Non randomised trials and cohort studies were examined where data on recurrence and function were available. DATA COLLECTION AND ANALYSIS Two reviewers (TJ and BP) independently selected the trials for inclusion in the review. Disagreements were solved by discussion. Where disagreement persisted and published results made data extraction difficult, we obtained clarification from the authors. REVMAN 5 was used for statistical analysis. Quality of the trials were assessed and allowances made for subgroup analysis and prevention of publication bias, using funnel plots if needed. MAIN RESULTS Ten randomised controlled trials were available for analysis. The quality of included studies was adequate, though in some trials the numbers were small and they were inadequately powered for equivalence or to detect significant differences. Comparisons were made between various modalities of treatments. There were no significant difference in recurrence rates or incontinence rates in any of the studied comparisons except in the case of advancement flaps. There were more recurrences in the glue plus flap group, a significant difference that favoured the flap only technique. It was also noted that Fibrin glue and advancement flap procedures report low incontinence rates.In the review of literature of non-randomised trials, most trials on fibrin glue indicate good healing in simple fistulae with low incontinence rates. AUTHORS' CONCLUSIONS There are very few randomized controlled trials comparing the various modalities of surgery for fistula in ano. While post operative pain, time to healing and discharge from hospital affect quality of life, recurrence and incontinence are the most important. As it turns out, there seems to be no major difference between the various techniques used as far as recurrence rates are concerned.The use of Fibrin glue and advancement flaps are associated with low incontinence rates.There is a crying need for well powered, well conducted randomised controlled trials comparing various modes of treatment of fistula in ano. Newer operations like the anal fistula plug and the LIFT procedure need to be evaluated by randomised clinical trials.

Abstract
: affecting sphincter integrity and continence. Traditional surgical and medical approaches are not without their limitations and may result in either comorbidity, such as fecal incontinence, or incomplete healing of the fistulae. Over the last 2 decades these limitations have led to a paradigm shift toward the use of biomaterials, and more recently cell-based therapies, which have met with variable degrees of success. This review discusses the traditional and current methods of treatment, as well as emerging and possible alternative approaches that may improve fistula healing.

Abstract
INTRODUCTION Fistula-in-ano can be associated with a number of conditions, including Crohn's disease. The majority, however, are classified as idiopathic or cryptoglandular. The aim of this study was to review the outcome of surgical management of fistula-in-ano in a specialist colorectal unit. MATERIALS AND METHODS One hundred and four consecutive patients underwent surgery for anal fistulae between 1st January 2000 and December 2004. Data was analysed in two main groups, according to the aetiology, cryptoglandular (n = 86) and Crohn's disease (n = 18). Follow-up data was available on 91 patients. RESULTS In the cryptoglandular group, 62 patients had an inter-sphincteric tract, of which 48 underwent a single-stage fistulotomy. Of those patients with a trans-sphincteric tract, six patients underwent a single-stage fistulotomy, 13 had a seton and staged fistulotomy. Follow-up data revealed that two fistulae recurred. The median number of procedures in this group was 1 (range 1-3). There was a significant difference in the inpatient stay depending of Park's classification (p = 0.001). In the Crohn's group, three patients with an inter-sphincteric tract underwent a single-stage fistulotomy, two patients with a trans-sphincteric tract had single-stage fistulotomy, and five required a loose seton and staged fistulotomy. Eight patients had multiple fistulae which required long-term setons. Four patients from this group eventually required proctectomy. In the Crohn's group, there was a significantly increased complexity of surgery and higher recurrence. This was reflected in an increased inpatient length of stay and a greater reliance on imaging (p = 0.001). The median number of procedures in this group was 3 (range 1-5). DISCUSSION The majority of cryptoglandular fistula-in-ano were treated by primary fistulotomy or staged fistulotomy with a loose seton. This was associated with a low recurrence rate and low rates of faecal incontinence. There was a low reliance on imaging techniques in this group. However, we would urge caution when dealing with fistula-in-ano related to Crohn's disease. In this group of patients, the fistulae tended to be more complex and require additional imaging and multiple procedures.

Abstract
AIM: To investigate a new technique of the anorectal fistula treatment with acellular extracellular matrix (AEM).
METHODS: Thirty patients with anorectal fistula were treated with AEM. All fistula tracts and primary openings were identified using conventional fistula probe. All tracts were curetted with curet and irrigated with hydrogen peroxide and metronidazole. The AEM was pulled into the fistula tract from secondary to primary opening. The material was secured at the level of the primary opening. The excess AEM was trimmed at skin level at the secondary opening.
RESULTS: All of the 30 patients had successful closure of their fistula after a 7-14 d follow-up. The healing rate of anal fistula in treatment group was 100%. The ache time, healing time and anal deformation of treatment group were obviously superior to traditional surgical methods.
CONCLUSION: Using AEM anal fistula plug in treatment that causes the anorectal fistula is safe and successful in 100% of patients. It can reduce pain, shorten disease course and protect anal function.

Abstract
BACKGROUND AND AIMS This study was undertaken to determine the incidence of and risk factors for anal incontinence after fistulotomy for intersphincteric fistula-in-ano. We also evaluated the role of anal manometry in preoperative assessment of intersphincteric fistula. MATERIALS AND METHODS A prospective, observational study was undertaken in 148 patients who underwent fistulotomy for intersphincteric fistula between January and December 2004. Functional results were assessed by standard questionnaire and anal manometry. Possible factors predicting postoperative incontinence were examined by univariate and multivariate regression analyses. RESULTS The mean follow-up period was 12 months. Postoperative anal incontinence occurred in 30 patients (20.3%), i.e., soiling in 6, incontinence for flatus in 27, and incontinence for liquid stool in 4. Fistulotomy significantly decreased maximum resting pressure (85.9 +/- 20.4 to 60.2 +/- 18.4 mmHg, P < 0.0001) and length of the high pressure zone (3.92 +/- 0.69 to 3.82 +/- 0.77 cm, P = 0.035), but it did not affect voluntary contraction pressure (164.7 +/- 85.2 to 160.3 +/- 84.8 mmHg, P = 0.2792). Multivariate analysis showed low voluntary contraction pressure and multiple previous drainage surgeries to be independent risk factors for postoperative incontinence. CONCLUSION Fistulotomy produces a satisfactory outcome in terms of eradicating sepsis and preserving function in the vast majority of patients with intersphincteric fistula with intact sphincters. However, sphincter-preserving treatment may be advocated for patients with low preoperative voluntary contraction pressure or those who have undergone multiple drainage surgeries. Preoperative anal manometry is useful in determining the proper surgical procedure.

Abstract
BACKGROUND AND AIMS The management of anal fistula is debatable. Although several procedures have been described, none of them is free from complications, such as anal incontinence and anal pain. The purpose of this study was to evaluate the employment of a glue composed of N-butil-2-cyanoacrylate and methacryloxysulfolane (Glubran 2) to treat fistula-in-ano. PATIENTS AND METHODS Twenty-one patients (14 men and 7 women) with cryptoglandular anal fistula were enrolled in the study and treated as day-cases. Fistulas were assessed both clinically and by trans-rectal endosonography with a rotating 10-MHz 360 degrees endoscopic probe. Assessment of continence was also performed. The fistula tract was identified, curetted and washed-out with normal saline and hydrogen peroxide; then the glue was injected from the syringe nozzle through a catheter previously inserted into the fistula. Additional treatments were performed when the first failed. RESULTS Five of seven simple fistulas (71.4%) healed with primary glue treatment; the other two needed second and third injections, and both healed. Ten of 14 (71.4%) complex fistulas healed with primary treatment; of the other four patients, one showed signs of intolerance to cyanoacrylate, which required re-intervention to remove the applied glue. In the second patient, treatment was successful after a second session; in the third case, three glue injections were required; while the fourth patient was lost at follow-up after three unsuccessful sessions. The ratio of cumulative healing with only one treatment was 15/21 (71.4%), and the ratio of overall healing after more than one session was 19/21 (90.2%). There was no sign of recurrence of the disease after 18 months of follow-up. CONCLUSION Cyanoacrylate glue seems to be ideal to treat fistula-in-ano, as it is a safe, cost-effective, repeatable and muscle-sparing technique. The incidence of recurrence is low, and post-procedure complicated fistulas or perianal abscesses were not reported.

Abstract
PURPOSE This prospective study was done to analyze the efficacy of commercial fibrin glue application in the healing of patients with fistulas-in-ano. METHODS This clinical trial of 36 patients was performed during the period from November 2003 to May 2004. Thirty men and six women were treated for a fistula-in-ano with commercial fibrin glue application. None of the patients had undergone prior attempts to correct fistulas-in-ano surgically. All patients received preoperative mechanical bowel preparation and prophylactic intravenous antibiotics. In the operating room, the patients underwent an anorectal examination under spinal anesthesia. The external and internal fistula tract openings were then identified. The fistula tract was curetted. Fibrin glue was injected into the external fistula opening until fibrin glue could be seen coming from the internal opening. No dressing was applied over the external opening. Thereafter, the patient was discharged. A 1-week course of oral antibiotics was prescribed. The patients were followed up for 70 weeks with a mean of 54 weeks (range 40-70 weeks). RESULTS The cause of the fistula-in-ano was cryptoglandular in all patients. The overall initial success rate was 77.8% (28/36). No complications were encountered related to the application. Two patients underwent a reapplication with fibrin glue and the fistulas of these patients were all closed. The overall success rate was 83.3% (30/36). CONCLUSION Fibrin glue application was thus found to be an easy, safe, effective, and useful alternative treatment in the management of fistulas-in-ano. However, our findings need substantiation by increasing the number of patients and prolonging the follow-up duration, as well as carrying out comparative studies.

Abstract
Biosurgical preparations designed to promote surgical hemostasis and tissue adhesion are now available to the urologist and are increasingly being used across all surgical disciplines. Fibrin sealant and gelatin thrombin matrix are the two most widely used bio-surgical adjuncts in urology. Complex reconstructive, oncologic, and laparoscopic genitourinary procedures are those most appropriate for sealant use. This article details the diverse urologic applications of biosurgical products in the management of urologic injuries and the promotion of wound healing.

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
Anal abscesses and fistulas are a common part of surgical practice. Most abscesses simply need to be drained and most fistulas can be safely laid open. Excessive probing should not be attempted when draining abscesses as this may lead to iatrogenic fistulas. A small percentage of fistulas are complex and very challenging to manage. Management involves an accurate diagnosis and a balance between eradication of the fistula and maintenance of continence. A decision should be made, based on clinical evaluation and anal ultrasound (if available), whether the fistula can be laid open. If it cannot be laid open, a loose seton is placed and the sepsis is allowed to settle. Once the sepsis is quiescent, a definitive repair can be attempted. There are various techniques available including rectal advancement flap, fibrin glue and cutaneous flaps all of which are discussed.

Abstract
BACKGROUND Injecting fibrin glue has proved to be an effective means of treating anal fistulas (AF). There has been some debate, however, as to whether this technique should be used on the AF often involved in Crohn's disease (CD). AIM To assess the effectiveness of injecting heterologous fibrin glue as a means of treating AF refractory to immunosuppressive treatment in patients with CD. METHODS Fourteen CD patients (five men and nine women, average age 42 years) presenting with refractory AFs were included in this study. Heterologous fibrin glue was injected into the fistula tract under general anaesthesia under continuous endosonographic monitoring using a 7.5-MHz blind linear probe. The patients were followed up clinically and ultrasonographically for 3 months after the procedure, and then at regular intervals. RESULTS Three months after the fibrin glue injection, the fistulas had completely dried up in 10 patients (71%), the leakage had decreased in one patient (7%), and no improvement was observed in the other three patients (21%). Endosonographic findings showed that the fistula tract had completely disappeared in two cases (14%). The fistula tract was found to be non-permeable in eight cases (57%), and no change in the fistula was observed in four patients (29%). At the end of the follow-up period [average 23.4 months (12-26 months)], the leakage had completely dried up in eight of the 14 patients (57%). No side effects were observed. CONCLUSION Nearly 2 years after the use of a heterologous fibrin glue to treat an AF, over half of the patients with CD showed clinical signs of remission. Because it is easy to use and harmless as well as being effective, this method provides a good alternative to classical methods of surgical treatment.

Abstract
OBJECTIVE Fibrin glue has been used as a sphincter sparing approach for the treatment of anal fistulae for two decades. However, there is uncertainty about its short and long-term efficacy. The objective of this review was to ascertain the role of fibrin glue in the management of anal fistulae, including assessment of recurrence rates, continence disturbance and other complications. METHODS We searched Medline (January 1966 to February 2004), the Cochrane database, and EMBASE using the terms anal fistulae, fistula-in-ano, and fibrin glue. Relevant papers from the reference lists of these articles and from the authors' personal collections were also reviewed. A systematic review of all articles relating to the use of fibrin glue in the treatment of anal fistulae was performed. This included 19 studies. Reviewers performed data extraction independently. Outcomes evaluated included recurrence rates, continence disturbance, septic complications, adverse drug reactions, and duration of follow-up. Heterogeneity of the clinical trials made direct comparisons difficult and meta-analysis impossible. RESULTS The success rates reported in published studies range from 0% to 100%. Differences in patient selection (including fistula aetiology and type), treatment protocols, and follow-up duration may contribute to such diverse results. CONCLUSIONS Fibrin glue is simple to use, has a minimal morbidity and should not affect later treatment options in the event of its failure. It is therefore theoretically attractive as a first line treatment in the management of those types of anal fistula in which it has been shown to work. However, further research into 'biological' glues is merited and these subject to randomised controlled study.

Abstract
BACKGROUND Despite advances in surgical, endoscopic, and percutaneous therapeutic techniques, pancreatic fistulas remain a source of significant morbidity and long-term patient discomfort. The intraoperative use of fibrin sealant has been used prophylactically to prevent formation of fistula. We recognized the potential use of fibrin glue as a therapeutic modality for successful resolution of low-output pancreatic fistulas. METHODS Three patients with low (<20 ml per day) output pancreatic fistulas underwent fluoroscopically directed injection of fibrin glue along their fistula tract. RESULTS All 3 patients underwent successful fibrin glue injection without procedural complication. All fistula output stopped, and the 3 patients remained asymptomatic at 1 year. CONCLUSIONS Fibrin glue inserted with image-guided catheter delivery systems may be a useful option in selected patients with low-output pancreatic fistulas.

Abstract
Abstract
Background
This study determined the long-term outcome after use of the loose-seton technique (LST) to eradicate complex fistula in ano.
Methods
Twenty patients whose complex fistula in ano was treated by the LST a minimum of 10 years previously were assessed by case-note review, supplemented where necessary by mailed and telephone interview.
Results
Eighteen patients had a trans-sphincteric and two a suprasphincteric fistula. There were seven supralevator and 12 ischiorectal secondary extensions. At short-term follow-up, a median of 6 months following seton removal, perianal sepsis had been eradicated in 13 of 20 patients. However, the long-term success rate of the LST was lower than that noted in the short term (four versus 13 of 20). Sixteen patients had persisting or recurrent sepsis, necessitating further surgery in 13. In the long term, external sphincter division was necessary to control sepsis in seven of the 20 patients compared with three of 20 patients at short-term follow-up. The rate of relapse in those with Crohn's disease and cryptoglandular fistula in ano was similar (five of six versus 11 of 14; P = 1·000). The fistula recurred in seven, 11 and 15 patients at 6, 15 and 60 months respectively after seton removal.
Conclusion
The success rate of the LST for complex fistula in ano falls over time. Counselling before seton removal should emphasize that, although most patients do not require sphincter division and some are cured by this technique, many patients develop further sepsis that usually requires surgery.

Abstract
PURPOSE We report our preliminary experience with the use of fibrin sealant to manage iatrogenic urinary tract injuries, complex urinary fistulas, and urological surgical complications. MATERIALS AND METHODS Topical fibrin sealant was used in 19 patients for iatrogenic urinary tract injury during gynecological or general surgical procedures (7), complex urinary fistulas (5) or urological surgical complications (7). RESULTS Successful resolution of the injury, fistula or complication was attained after a single application of fibrin sealant in the 18 patients (94.7%) in whom a direct injection technique was used. The only failure (formation of a vesicovaginal fistula) occurred with the air driven sprayed sealant delivery technique after sutured closure of iatrogenic cystotomy during vaginal hysterectomy. CONCLUSIONS Liquid fibrin sealant appears to be safe and prudent for use in urological "damage control" from trauma, fistulas or surgical complications. Direct injection over a sutured urinary anastomosis appears to be highly effective in preventing urinary drainage. Additional study is needed to define further the role and best use of tissue adhesives in urology.

Abstract
OBJECTIVE: To conduct a prospective audit of all patients presenting with anal fistula at St. Mark's Hospital during one calendar year and to compare the presentation and outcome of this cohort with previous reports from this institution. PATIENTS AND METHODS: All patients undergoing examination under anaesthetic (EUA) for anal fistula during 1997 were studied. All fistulae were anatomically classified and operative procedures recorded. During a mean follow-up period of 14 months details of healing, recurrence and function were gathered. RESULTS: 98 patients with a mean age of 43.7 years were assessed. 86 (88%) patients had fistulae of cryptoglandular (idiopathic) origin. Fistulae were superficial in 11 (11%) patients, intersphincteric in 30 (31%) patients, trans-sphincteric in 52 (53%) patients, suprasphincteric in 3 (3%) patients and extra-sphincteric in 2 (2%) patients. 49 (50%) fistulae were classified as complex. Eradication of fistulae with preservation of function was achieved in 89 (91%) patients. Fistula recurrence occurred in 4 (4%) cases. Ten (10%) patients had some degree of incontinence, 9 (9%) of whom had undergone previous fistula surgery. Nine (9%) patients still had setons in situ at the end of the follow-up period. CONCLUSIONS: A greater proportion of difficult fistulae was seen during the year compared with previous studies from St. Mark's. Despite this a satisfactory outcome was achieved in the vast majority with a relatively low rate of disturbed function. Previous fistula surgery is a risk factor for incontinence, which can usually be managed conservatively.

Abstract
Because current techniques for examination and imaging of perianal fistulas tend to underestimate the extent, location, and course of perianal fistulas--information essential for decisions about surgical management--the use of hydrogen peroxide was investigated as an image-enhancing contrast agent for confirmation of the presence of and improvement in the depiction of fistulas during endoanal ultrasonography (US). After conventional endoanal US was performed with a side-fire 7.5- or 10.0-MHz rotating endoprobe, external perianal openings were cannulated and approximately 1 mL of peroxide was administered. After reinsertion of the endoprobe, the entire course of the echogenic fistula, including its relation to the internal and external sphincters and the levator ani muscle, was depicted in real time in three dimensions. This depiction of fistulas permits accurate classification, which facilitates surgical planning. In experience with more than 60 patients, peroxide-enhanced endoanal US was found to be a useful technique for documentation of the presence, number, and internal course of perianal fistulas and for characterization of abnormalities seen at endosonography performed without use of contrast enhancement. In addition, the technique permitted surgeons to stratify patients into treatment groups and has been especially useful for planning surgical treatments.

Abstract
Current surgical management of deep partial-thickness and full-thickness burn wounds involves early excision and grafting. Blood loss during these procedures can be profound, thus prompting the use of topical hemostatic agents to control and minimize hemorrhage during grafting. The primary endpoint of this multicenter trial was to evaluate the efficacy of fibrin sealant as a topical hemostatic agent during skin grafting. The secondary endpoint was to obtain data to support the existing safety profile of a human fibrin sealant (FS) in participating patients as indicated by the type, severity, and frequency of any adverse events within the 24-hour postoperative period. A multicenter prospective, open label, Phase III multicenter, randomized, comparative clinical trial evaluated the use of fibrin sealant in burn patients undergoing skin graft procedures. Each patient served as his or her own control in this randomized, unblinded study of the effect on time to hemostasis in donor sites treated with the investigational FS product. At operation, 1 contiguous donor skin harvest site was bisected into 2 equal halves, 1 of which was then randomly selected and treated with fibrin sealant. At the end of the fibrin sealant application, the time to hemostasis in each of the donor site halves was identified by the operating surgeon and recorded by the research coordinator. The use of any other topical hemostatic agents was prohibited. A significant difference (P < .001) was demonstrated in the mean time to hemostasis between the fibrin sealant treated donor sites when compared painwise to the control sites. The significant difference was consistent across the 6 participating study centers. There were no adverse events associated with the use of fibrin sealant. The investigational FS product was shown to be efficacious, because it significantly decreases the time to hemostasis at the donor skin harvest site in patients undergoing skin grafting and was noted not to cause any adverse reactions.
