Abstract
Pelvic magnetic resonance (MR) imaging is currently the standard for imaging perianal Crohn disease. Perianal fistulas are a leading cause of patient morbidity because closure often requires multimodality treatments over a prolonged period of time. This review summarizes clinically relevant anal sphincter anatomy, imaging methods, classification systems, and treatment objectives. In addition, the MR appearance of healing perianal fistulas and fistula complications is described. Difficult imaging tasks including the assessment of rectovaginal fistulas and ileoanal anastomoses are highlighted, along with illustrative cases. Emerging innovative treatments for perianal Crohn disease are now available and have the promise to better control sepsis and maintain fecal continence. Different treatment modalities are selected based on fistula anatomy, patient factors, and management goals (closure versus sepsis control). Radiologists can help maximize patient care by being familiar with MR imaging features of perianal Crohn disease and knowledgeable about what features may influence therapy decisions. © RSNA, 2017 Online supplemental material is available for this article.

Abstract
OBJECTIVE Local application of adipose-derived mesenchymal stem cells (ADSC) represents a novel approach for the management of perianal fistula in patients with Crohn's disease. A randomised study on an animal model was performed to investigate the efficacy and to detect the distribution of implanted ADSCs by bioluminescence (BLI). MATERIALS AND METHODS A caecostomy was used as a fistula model in 32 Lewis rats. The ADSCs were isolated from transgenic donor expressing firefly luciferase. Animals were randomly assigned to groups given injections of 4 × 106 cells (n = 16, group A) or placebo (n = 16, group B) in the perifistular tissue. Fistula drainage assessment was used to evaluate the fistula healing. After application of D-luciferin, cell viability and distribution was detected using an IVIS Lumina XR camera on days 0, 2, 7, 14 and 30. RESULTS The fistula was identified as healed in 6 (38%) animals in group A vs. 1 case (6.3%) in group B (p = .033). The BLI was strongest immediately after administration of ADSCs 31.2 × 104 (6.09-111 × 104) p/s/cm2/sr. The fastest decrease was observed within the first 2 days when values fell by 50.2%. The BLI 30 days after injection was significantly higher in animals with healed fistulas - 8.23 × 104 (1.18-16.9 × 104) vs. 1.74 × 104 (0.156-6.88 × 104); p = .0393. CONCLUSIONS Local application of ADSCs resulted in significantly higher fistula closure rate on an animal model. BLI monitoring was proved to be feasible and showed rapid reduction of the ADSC mass after application. More viable cells were detected in animals with healed fistula at the end of the follow-up.

Abstract
AIM Management of fistulating perianal Crohn's disease (fpCD) is a significant challenge for a colorectal surgeon. A recent survey of surgical practice in this condition showed variation in management approaches. As a result we set out to devise recommendations for practice for UK colorectal surgeons. METHOD Results from a national survey were used to devise a set of potential consensus statements. Consultant colorectal surgeons were invited to participate in the exercise via the previous survey and the mailing list of the professional society. Iterative voting was performed on each statement using a five-point Likert scale and electronic voting, with opportunity for discussion and refinement between each vote. Consensus was defined as > 80% agreement. RESULTS Seventeen surgeons and two patient representatives voted upon 51 statements. Consensus was achieved on 39 items. Participants advocated a patient-centred approach by a colorectal specialist, within strong multidisciplinary teamworking. The use of anti-TNFα therapy is advocated. Where definitive surgical techniques are considered they should be carefully selected to avoid adverse impact on function. Ano/rectovaginal fistulas should be managed by specialists in fistulating disease. Stoma or proctectomy could be discussed earlier in a patient's treatment pathway to improve choice, as they may improve quality of life. CONCLUSION This consensus provides principles and guidance for best practice in managing patients with fpCD.

Abstract
Anal fistula is common in patients with Crohn's disease (CD) and leads to significant morbidity. The efficacy of seton drainage combined with anti-tumor necrosis factor-α monoclonal antibody (anti-TNF-α) or immunosuppressant in the treatment of CD-related anal fistula remains unclear. The aim of the present study was to compare the efficacy between seton drainage combined with anti-TNF-α and seton drainage combined with immunosuppressant postoperatively on the treatment of CD-related anal fistula. A total of 65 patients with CD-related anal fistula who had received seton drainage combined with postoperative medication were divided into an antibiotics only group, anti-TNF-α group and immunosuppressant group; all patients were treated with antibiotics. Fistula closure, external orifice exudation rate and recurrence rate were assessed among these patients. The duration of follow-up ranged from 3 to 84 months with an average of 25.3 months. There were 11 (16.9%) cases of recurrence after seton drainage, 9 of which underwent a second seton drainage. In the total study group, 34 (52.3%) cases achieved complete fistula closure, and 10 (15.4%) cases showed external orifice exudation. No significant difference was found among these three groups, regarding fistula closure rate, closure time of fistula and recurrence rate. The external orifice exudation rate was significantly higher in the anti-TNF-α group compared with the antibiotics only group and immunosuppressant group (P=0.004 and P=0.026, respectively). Seton drainage is an effective treatment for CD-related anal fistula. The efficacy is similar whether combined with anti-TNF-α or immunosuppressant.

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
INTRODUCTION Anal fistula in Crohn's disease is frequently an intractable condition. Methods of treatment are still debated because the results of various procedures are unsatisfactory. Available studies show that results can be improved using a combination of surgical and medical methods. Most patients undergo rather palliative than radical, curative procedures such as incision and drainage of abscesses and prolonged non-cutting seton placement. Surgery is combined today with biological therapy using infliximab, a murine-human chimeric monoclonal antibody against TNF-α or adalimumab a human monoclonal anti-TNF antibody to increase the healing process and in an attempt to prevent fistula recurrence. METHODS Medical records of 23 patients who were treated for anal fistulas in Crohn's disease between 2012 and 2014 were retrospectively evaluated. RESULTS There were 10 (43%) males and 13 females. The mean age was 39 years (range 29-60 years). Median duration of CD before present treatment was 6 years (range 1-15 years). Closure of all fistulas in 6 months was achieved in eight (35%) patients, whereas reduction of at least 50% from base line in the number of draining fistulas occurred in four (17%) patients. CONCLUSION Palliative and combined therapy for anal fistulas in Crohn's disease with surgery and infliximab or adalimumab therapy is an effective treatment for some patients.

Abstract
Fistulae-in-ano represent one of the more challenging anorectal diseases faced by surgeons, as appropriate management requires careful balance between the need for local sepsis control and patients' desire to maintain fecal continence. The ligation of intersphincteric fistula tract (LIFT) procedure, first described by Rojanasakul and colleagues in 2007, represents a sphincter-sparing technique for fistula management which has become our method of choice for transsphincteric fistulas. With this technique, patients frequently enjoy successful fistula healing., or, at worst, conversion to a less complex fistula tract. Here, we describe and illustrate our surgical approach and review success and recurrence rates presented in the published literature.

Abstract
Perianal sepsis is a common condition ranging from acute abscess to chronic fistula formation. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. The key to successful treatment is the eradication of the primary track. As surgery may lead to a disturbance of continence, several sphincter-preserving techniques have been developed. This consensus statement examines the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
Perianal fistulas in Crohn's disease are common and difficult to treat. Their aetiology is poorly understood. Assessment is clinical, endoscopic and radiological, and management is undertaken by a multidisciplinary team of gastroenterologists, surgeons and radiologists. Surgical drainage of the fistula tract system with the placement of loose setons precedes combined therapy with immunosuppressant and anti-TNFα agents in most patients. Proctitis should be rigorously eliminated where possible. Definitive surgical repair is sometimes possible and diversion or proctectomy are occasionally required. Combined medical and surgical management represents a promising avenue for the future.

Abstract
Background Healing rates after surgical closure for high perianal fistula in patients with Crohn’s disease are even more disappointing than in patients with cryptoglandular fistulas. The objective was to improve healing rates by combining the well-known mucosal advancement flap with platelet-rich plasma. Methods A prospective pilot study was conducted in one tertiary referral centre. Consecutive patients with primary or recurrent Crohn’s disease-related high perianal fistulas, defined as involving the middle and/or upper third parts of the anal sphincter complex, were included. A staged procedure was performed with non-cutting seton treatment for 3 months first, followed by a mucosal advancement flap with injection of platelet-rich plasma into the fistula tract. Results Ten consecutive patients were operated on between 2009 and 2014. Half (50 %) of the patients had undergone previous fistula surgery. Mean follow-up was 23.3 months (SD 13.0). Healing of the fistula was 70 % (95 % confidence interval, 33–89 %) at 1 year. One (10 %) patient had a recurrence, and in two (20 %) patients, the fistula was persistent after treatment. An abscess occurred in one (10 %) patient. The median post-operative Vaizey score was 8.0 (range 0–21), indicating a moderate to severe continence impairment. Conclusions The results of combining the mucosal advancement flap with platelet-rich plasma in patients with Crohn’s disease-related high perianal fistulas are moderate with a healing rate of 70 %. Further investigation is needed to determine the benefits and risks on continence status for this technique in this patient population.

[PMID: 25852290 PMCID: PMC4385552 DOI: 10.3748/wjg.v21.i13.4020] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2014] [Revised: 10/22/2014] [Accepted: 11/11/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To check the efficacy of the PERFACT procedure in highly complex fistula-in-ano.
METHODS: The PERFACT procedure (proximal superficial cauterization, emptying regularly fistula tracts and curettage of tracts) entails two steps: superficial cauterization of mucosa at and around the internal opening and keeping all the tracts clean. The principle is to permanently close the internal opening by granulation tissue. This is achieved by superficial electrocauterization at and around the internal opening and subsequently allowing the wound to heal by secondary intention. Along with this, all the tracts are curetted and it is ensured that they remain empty and clean in the postoperative period until they heal completely. The latter step also facilitates the closure of the internal opening by preventing collected fluid in the tracts from entering the internal opening and thus not letting it close. Objective incontinence scoring was done preoperatively and 3 mo after the operation.
RESULTS: Fifty-one patients with complex fistula-in-ano were prospectively enrolled. The median follow-up was 9 mo (5-14 mo). The mean age was 42.7 ± 11.3 years. Male:female ratio was 43:8. Fistula was recurrent in 76.5% (39/51), horseshoe in 50.1% (26/51), had multiple tracts in 52.9% (27/51), had an associated abscess in 41.2% (21/51), was anterior in 33.3% (17/51), the internal opening was not found in 15.7% (8/51) and 9.8% (5/51) of fistulas had a supralevator extension. Seven patients were excluded (5 lost to follow up, 2 with tuberculosis leading to/associated with fistula-in-ano). The success rate was 79.5% (35/44) and the recurrence rate was 20.5% (9/44). Out of these recurrences, three underwent reoperation (2 PERFACT procedure, 1 fistulotomy) and all three were successful. Thus, the overall success rate was 86.4%. The only complication was a non-healing tract in 9.1% (4/44) of patients. There was no significant change in objective incontinence scores three months after the operation. The pain was minimal, with all patients resuming their normal activities within 72 h of the operation.
CONCLUSION: The PERFACT procedure is a new effective method for complex fistula-in-ano, effective even in fistula associated with abscess, supralevator fistula-in-ano and where the internal opening is non-localizable.

Abstract
BACKGROUND The management of high anal fistula is often complicated and challenging. In spite of numerous new techniques, the advancement flap technique remained an integral procedure in its management. The purpose of this study was to determine the long-term outcome of advancement flap procedures for high anal fistulas. METHODS A retrospective review of patients who have undergone an advancement flap procedure for high anal fistula of cryptoglandular origin from June 2003 to April 2012 was performed. Patients were contacted via telephone to evaluate their continence status using the Wexner score. RESULTS Sixty-one patients with a median age of 48 (range, 19-74) years and a median follow-up of 6.5 (range, 1-59) months were evaluated. Fifty-three (86.9 %) patients had successful surgery while 8 (13.1 %) failed the procedure. Four of them underwent subsequent surgery. Of the 53 patients who had a successful procedure, 27 were successfully contacted for a telephone interview. Twenty-one (77.8 %) of them reported a Wexner score of '0'. Two (7.4 %) patients had a Wexner score of <4, another 2 had a score of '4' and '10', while the last 2 patients had a score of >10. CONCLUSION Advancement flap procedure is effective in the management of high anal fistulas with an acceptable success rate. The majority of the patients experienced good anal continence.

Abstract
PURPOSE The purpose of this study was to assess primary healing, recurrence and continence after endoanal advancement flap repair (EAFR). PATIENTS AND METHODS Seventy-seven patients with fistulas-in-ano of different etiologies received endoanal advancement flap repair between 1997 and 2009. This is a prospective, non-randomized, single-centre, single-surgeon study. RESULTS Follow-up data was available for 71 patients. 47.9 % had cryptoglandular fistulas. In 40.8 %, the fistulas were due to chronic inflammatory bowel disease. In 11.3 %, the fistula was a consequence of treatment for cancer. Primary healing was observed in 41 of the cases (57.7 %). The median time to recurrence was 27 months (mean 43.43 ± 48.11) and differed significantly across the patient groups: cryptoglandular origin 51 months (mean 57.09 ± 52.57), condition after cancer treatment 43 months (mean 31 ± 23.142), inflammatory bowel disease 11 months (mean 23.65 ± 32.47) (p < 0.01). Preoperatively, 31 (44.3 %) of the patients had impaired continence vs 30 (42.9 %) postoperatively. Overall, postoperative mean Cleveland Clinic incontinence score values improved significantly (preoperative 3.74 ± 4.558 vs postoperative 2.68 ± 4.752, p = 0.03). CONCLUSIONS Full-thickness endoanal advancement flap repair is a successful treatment option for a range of fistula etiologies. Overall, fistula aetiology proved to be prognostically more relevant than fistula location. Fistulas associated with chronic inflammatory bowel disease were found to have a significantly higher rate of recurrence and shorter time to recurrence at long-term follow-up. Repeat interventions do not negatively impact postoperative continence.

Abstract
BACKGROUND The treatment of complex fistulae-in-ano is challenging and often includes a number of operations due to high rates of recurrence. Recently, techniques using in vitro expanded adipose tissue-derived stem cells have been described. We describe a novel treatment for cryptoglandular fistulae used in 7 patients, using a combination of surgical closure of the internal opening and real-time autologous adipose tissue-derived regenerative cells (ADRC)-enhanced lipofilling, without need for in vitro expansion. METHODS Following exclusion of active perianal sepsis, patients underwent a standard tumescent liposuction procedure, harvesting ~300 to 400 mL of raw lipoaspirate. The lipoaspirate was prepared in real time, using the Celution 800/CRS system to obtain the stromal vascular fraction containing ADRCs. After excision of the fistula tract and closure of the internal orifice, fresh ADRC-enhanced lipoaspirate was injected into and around the fistula tract. RESULTS At 6-months' follow-up, 5 of 7 (71.4%) patients showed clinical signs of fistula closure; one of these patients had a recurrence at 10 months due to sepsis. The remaining 4 patients (57.1%) all had complete fistula closure at a median of 46 months' follow-up. There were no adverse events associated with the technique, and no new incontinence. CONCLUSION Treatment of cryptoglandular fistulae-in-ano with ADRC-enhanced lipofilling appears feasible and safe, and may add to the range of procedures that can be used to treat this difficult problem.

Abstract
BACKGROUND Anorectal fistula represents an epithelized communication path of infectious origin between the rectum or anal canal and the perianal region. The association of endoscopic surgery with the minimally invasive approach led to the development of the video-assisted anal fistula treatment. AIM To describe the technique and initial experience with the technique video-assisted for anal fistula treatment. TECHNIQUE A Karl Storz video equipment was used. Main steps included the visualization of the fistula tract using the fistuloscope, the correct localization of the internal fistula opening under direct vision, endoscopic treatment of the fistula and closure of the internal opening which can be accomplished through firing a stapler, cutaneous-mucosal flap, or direct closure using suture. RESULTS The mean distance between the anal verge and the external anal orifice was 5.5 cm. Mean operative time was 31.75 min. In all cases, the internal fistula opening could be identified after complete fistuloscopy. In all cases, internal fistula opening was closed using full-thickness suture. There were no intraoperative or postoperative complications. After a 5-month follow-up, recurrence was observed in one (12.5%) patient. CONCLUSION Video-assisted anal fistula treatment is feasible, reproducible, and safe. It enables direct visualization of the fistula tract, internal opening and secondary paths.

Surgical treatment of perianal fistulizing Crohn's disease: from lay-open to cell-based therapy--an overview. ScientificWorldJournal 2014; 2014:146281.

Abstract
Background. Perianal Crohn's disease (CD) can be challenging. Despite the high incidence of fistulizing CD, literature lacks clear guidelines. Several medical, surgical, and combined treatment modalities have been proposed, but evidences are scarce. Methods. We searched the literature to assess the facets of perianal CD, with particular focus on complex fistulae. Disease epidemiology, classification, diagnosis, activity scoring systems, and medical-surgical treatments were assessed. Results. Perianal fistulizing CD is common, frequently associated with upper gastrointestinal and colorectal CD. Complex fistulas often require repeated treatments. Continence is a major concern when dealing with repeated procedures. A prudent pathway is to resolve active sepsis and to limit damages, delaying a definitive treatment to the time when acute phase has been controlled. The improved diagnostic techniques allow better preoperative planning and are useful in monitoring the response to treatment. Besides newer devices, cell-based treatments are promising tools which have recently enriched the treatment portfolio. However, the need for proctectomy is still disturbingly high in CD patients with complex perianal fistulae. Conclusions. Perianal CD can impair quality of life and lead to need for proctectomy. A staged approach is reasonable. Treatment success can be improved by multimodal treatment and collaborative management by experienced gastroenterologists and surgeons.

Abstract
BACKGROUND The management of perianal Crohn's fistulas represents a significant challenge. A combination of medical and surgical therapy, guided by radiology, is often required. AIM To review systematically the literature to assess fistula healing rates with medical treatment (anti-TNF-α therapies ± immunomodulators) or surgical treatment alone, compared with combined medical and surgical treatment in fistulising perianal Crohn's disease (CD). METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Two independent reviewers searched the literature. RESULTS Twenty-four articles were included. The total population was 1139 patients; 460 (40%) received single treatment with either medical or surgical therapy, and 679 (60%) received combined medical and surgical therapy. Eight studies compared single and combination therapy, with a total population of 797 patients (single therapy: n = 448, combination therapy: n = 349). In the single therapy group, 191/448 were in complete remission (43%). This was lower than the healing rate of the combination therapy group 180/349 (52%). No response to therapy was noted in 34% (153/448) of the single therapy group compared with 23% (80/349) of the combination group. CONCLUSIONS Combined surgical and medical (anti-TNF-α ± immunomodulators) therapy may have additional beneficial effects on perianal fistula healing in patients with Crohn's disease, compared with surgery or medical therapy alone. A well-designed Crohn's perianal fistula clinical trial is required in a multidisciplinary medical and surgical setting, with clearly defined end points of clinical (and likely patient reported outcomes) and radiological healing.

Abstract
AIM The Biodesign(®) anal fistula plug was introduced as a means of obliterating the fistula tract and promoting healing through biocompatibility. The results demonstrated unexplained variations from good to bad. This report analysed the results of a retrospective multicentre study. METHOD All plug procedures performed in four Stockholm hospitals between June 2006 and June 2010 were identified and studied using a common protocol. The outcome after the first plug-insertion procedure was assessed by chart review performed a minimum of 8 months after plug insertion. Cox proportional-hazards models were used to assess the associations of various factors with fistula healing. RESULTS One-hundred and twenty-six patients (mean age 47 years) were deemed suitable for the plug procedure. Eighty-five per cent of fistulae were cryptoglandular, 64% of patients were male and a mean of 2.9 previous fistulae procedures had been performed. All patients, except four, had an indwelling seton at the time of the plug procedure, which was performed in accordance with previously established principles of day surgery. After a median of 13 months, 30 (24%) fistulae had closed with no discomfort or secretion reported. The outcome in the four hospitals varied from 13% to 33% with similar numbers of patients in each hospital. A success rate of 12% was observed for patients with anterior fistula compared with 32% for those with posterior tracks [hazard ratio (HR) for successful healing = 2.98; 95% CI: 1.01-8.78) and 41% for those with a lateral internal opening (HR = 3.76; 95% CI: 1.03-13.75). Age, sex and number of previous procedures were not associated with healing. CONCLUSION Four independent patient groups showed low success rates after the first plug-insertion procedure. Anterior fistulae were much less likely to heal compared with fistulae in other locations.

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

Abstract
Sphincter-preserving approaches to treat anal fistula do not jeopardize continence; however, healing rates are suboptimal. In this context, ligation of the intersphincteric fistula tract (LIFT) can be considered promising offering high success rates and a relatively simple procedure. This review aimed to investigate the outcomes of LIFT to treat anal fistula. We conducted a systematic review of the Pubmed, Web of Science, and Cochrane databases, to retrieve all relevant scientific original articles and scientific abstracts (Web of Science) related to the LIFT procedure for anal fistula between January 2007 and March 2013. The search yielded 24 original articles including 1,110 patients; these included one randomized controlled study, three case control studies, and 20 case series. Most studies included patients with trans-sphincteric or complex fistula, not amenable to fistulotomy. During a pooled mean 10.3 months of follow-up, the mean success, incontinence, intraoperative, and postoperative complication rates were 76.4, 0, 0, and 5.5%, respectively. A sensitivity analysis showed that the impact on success in terms of follow-up duration, study size, and combining other procedures was limited. There was no association between pre-LIFT drainage seton and success of LIFT. Ligation of the intersphincteric fistula tract appears to be an effective and safe treatment for trans-sphincteric or complex anal fistula. Combining other procedures and a pre-LIFT drainage seton does not seem to confer any added benefit in terms of success. However, given the lack of prospective randomized trials, interpretation of these data must be cautious. Further trials are mandatory to identify predictive factors for success, and true effectiveness of the LIFT compared to other sphincter-preserving procedures to treat anal fistula.

Abstract
AIM This study aimed to evaluate the long-term outcome of the anal fistula plug in the treatment of anal fistula of cryptoglandular origin. METHOD A review of all patients who had at least one anal fistula plug inserted from March 2007 to August 2008 was performed. Only anal fistulae of cryptoglandular origin were included. Success was defined as the closure of the external opening with no further purulent discharge or collection. RESULTS Thirty anal fistula plugs were inserted in 26 patients [median age 40 (26-70) years]. Twenty-six of the fistulae were transsphincteric and three were suprasphincteric. One patient had a high intersphincteric fistula, which was the only fistula that did not have a seton inserted. The median duration between seton insertion and the plug procedure was 12 (4-28) weeks. The median length of the fistula tract was 3 (1-7.5) cm. After a median follow-up of 59 (13-97) weeks, 26 (86.7%) fistulae recurred. Of the 26 failures, the median time to failure was 8 (2-54) weeks. Subsequent surgical interventions were performed in 20 of the failures. CONCLUSION The role of the fistula plug in the management of anal fistula of cryptoglandular origin remains debatable and warrants further evaluation.

Abstract
Symptoms thought related to hemorrhoids must be carefully considered before intervention. The first line of therapy for any hemorrhoidal complaint remains conservative management with increased fluid and fiber intake and appropriate modification of toileting behavior. Bleeding in grades 1 and 2 hemorrhoids that does not respond to this can be satisfactorily and safely managed with office-based therapies; some grade 3 hemorrhoids would also respond to this, though more treatment sessions would likely be required. Operative therapy is the best choice for management of persistently symptomatic grade 2 disease and for grades 3 and 4 symptomatic hemorrhoids as well. With proper patient selection and preparation, along with a familiarity with instrumentation and techniques, good results can be obtained with newer operative interventions for internal hemorrhoids. Outcomes must always be compared with those obtained with classic excisional hemorrhoidectomy.

Abstract
Crohn's disease is a chronic inflammatory disease which may involve any segment of the gastrointestinal tract, most frequently the terminal ileum, the large intestine, and the perianal region. The symptoms of perianal Crohn's disease include skin disorders, hemorrhoids, anal ulcers, anorectal stenosis, perianal abscesses and fistulas, rectovaginal fistulas and carcinoma of the perianal region. The perianal manifestations of Crohn's disease cause great discomfort to the patient and are among the most difficult aspects to treat. Management of perianal disease requires a combination of different imaging modalities and a close cooperation between gastroenterologists and dedicated surgeons.

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.

Abstract
AIM Conventional surgery for complex anal fistula (AF) is associated with continence disturbance and recurrence. In the hope of reducing these we developed a new mechanical device, the 'fistulectome', to excise the entire fistula tract. METHOD Between March 2001 and April 2011, 136 patients underwent surgery for a complex AF using the fistulectome. All fistulae were cryptoglandular in origin. Five patients were lost to follow up and were excluded from the analysis. RESULTS Of the 131 fistulae, 76 were trans-sphincteric, 14 were suprasphincteric and 16 were extrasphincteric. Seven had a horseshoe extension and 18 were unclassified. Of the 131, 108 had recurred after conventional fistulotomy performed at another centre and 23 were primary. The mean duration of follow up was 34.6 months, the mean hospital stay was 5 days and the healing time was 14 days. Recurrence, flatus incontinence and soiling occurred in 17 (12.9%), four (3.5%) and two (1.52%) patients. CONCLUSION The results of this series suggest that coring-out of a fistula using a fistulectome may be a valid treatment for complicated anal fistula.

Abstract
INTRODUCTION Management of fistula-in-ano requires understanding of both perianal and rectal anatomy, as well as the surgical approaches available to ensure the highest possible postoperative continence and wound healing. Further, high rates of recurrence with medical management commonly bring these patients under the care of the colorectal surgeon after variable periods of failed conservative management. Novel techniques provide surgeons with tools to treat increasingly complex fistulas with a focus on maintaining sphincteric functionality and limiting recurrence. METHOD This manuscript presents our practice, including perioperative decision making regarding surgical approach, in managing patients with fistula-in-ano. CONCLUSION Familiarity with these techniques prepares the general surgeon and colorectal surgeon to improve wound healing and functional outcomes in these patients, especially with complex disease involving the external and internal anal sphincters.

Abstract
AIM Ligation of the intersphincteric fistula tract (LIFT) is a novel sphincter-preserving technique for anal fistula. This pilot study was designed to evaluate the results in patients with a recurrent fistula. METHOD Seventeen patients [nine men; median age 49 (range, 30-76) years] with a recurrent trans-sphincteric fistula were treated with a LIFT procedure between June 2008 and February 2011. All were followed prospectively for a median of 16 (range, 5-27) weeks with clinical examination. Fifteen followed for 13.5 (range, 8-26) months by clinical examination also had three-dimensional (3D) anal ultrasound. RESULTS The duration of the procedure was 35 (range, 18-70) min. One patient developed a small local haematoma and one had a subcutaneous infection, but otherwise there was no morbidity. At follow up, 11 (65%) patients had a successful closure, two (12%) had a remaining sinus and four (23%) had a persistent fistula. The incidence of persistent or recurrent fistulae at 13.5 months was six (40%) of 15 patients. No de novo faecal incontinence was reported. CONCLUSION LIFT is a safe procedure for patients with recurrent anal fistula, with healing at short-term and medium-term follow-up comparable with or superior to that of other sphincter-preserving techniques. Larger studies with a longer follow up are needed to define the ultimate role of LIFT in patients with recurrence.

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
BACKGROUND It was the aim of this prospective study to analyze both the feasibility and preliminary results of video-assisted anal fistula treatment (VAAFT) combined with advancement flap repair for complex fistulas in Crohn's disease. METHODS All patients with perianal Crohn's disease suffering from complex fistulas who underwent definitive surgery using VAAFT combined with advancement flap repair were prospectively enrolled in the study. Only complex fistulas with concurrent stable disease and without any evidence of severe inflammatory activity or perianal sepsis were treated using the VAAFT technique. Patients with Crohn's proctitis or prior proctectomy were not candidates for the procedure. VAAFT was performed by using the VAAFT equipment (Karl Storz, Tuttlingen, Germany). Key steps included visualization of the fistula tract and/or side tracts using the fistuloscope and correct localization of the internal fistula opening under direct vision with irrigation. Diagnostic fistuloscopy was followed by advancement flap repair. In addition to feasibility, primary end points included detection of side tracts, success and continence status (assessed by the Cleveland Clinic Incontinence Score). Success was defined as closure of both internal and external openings, absence of drainage without further intervention and absence of abscess formation. Follow-up information was derived from clinical examination 3, 6 and 9 months postoperatively. RESULTS Within a 3-month observation period (September to November 2011), VAAFT was attempted in 13 patients with Crohn's associated complex fistulas. The completion rate was 85% (11/13). In these 11 patients (median age 34 years, 64% females), complex fistulas were transsphincteric (8), suprasphincteric (2) and recto-vaginal (1). Forty-six percent (5/11) had concomitant therapy with biologic drugs. In 36% (4/11), VAAFT was performed with fecal diversion. Median duration of surgery was 22 (range 18-42) minutes. Using VAAFT, additional side tracts not detected preoperatively could be identified in 64% (7/11). No morbidity occurred. After a mean follow-up of 9 months, the success rate was 82% (9/11). No deterioration of continence was documented (Cleveland Clinic Incontinence Score 2.4 vs. 1.6, p > 0.05). CONCLUSION Preliminary results of the addition of the VAAFT technique to advancement flap repair in Crohn's fistulas demonstrate that this leads to a high identification rate of occult side tracts with encouraging short-term healing rates. Moreover, a completion rate of 85% seems promising.

Abstract
AIM Endorectal advancement flaps are an established treatment for high transsphincteric and suprasphincteric fistulae. The outcome of a repeat procedure in the case of flap breakdown and fistula recurrence remains unclear. The aim of the study was to analyse the outcome of repeat endorectal advancement flaps. METHODS We retrospectively analysed patients with a repeat endorectal advancement flap procedure after flap breakdown and recurrence of fistula-in-ano of cryptoglandular origin who had been treated in our unit between 1994 and 2010. RESULTS In all, 97 patients underwent an endorectal advancement flap procedure for fistula-in-ano and, of these, nine patients (five men, four women, 9.3%) subsequently underwent a repeat procedure due to flap breakdown. Median age was 40 years (range 25-60). Median follow-up time was 85 months (range 26-136). Seven full-thickness and two mucosal flap repeat procedures were performed because of eight transsphincteric and one suprasphincteric fistulae. The repeat procedure was successful in seven (78%) patients. In one of the two patients with repeat flap failure, a third flap procedure failed again. Disturbances of postoperative faecal incontinence were observed in five (55%) patients. Overall, the median postoperative Vaizey faecal incontinence score was 1 (range 0-4). CONCLUSION Repeat endorectal advancement flap procedures are feasible and associated with a low recurrence rate and mild postoperative faecal incontinence. Therefore, a repeat procedure is a viable option in the case of a flap breakdown and fistula recurrence.

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
OBJECTIVE To evaluate the long-term clinical and manometric results of fistulotomy and sphincter reconstruction for the treatment of complex fistula-in-ano. BACKGROUND Complex fistula-in-ano is difficult to treat due to the occurrence of postoperative anal incontinence and the high rate of recurrence. METHODS Seventy patients who were diagnosed with complex fistula-in-ano and underwent fistulotomy and sphincter reconstruction between October 2000 and October 2006 were analyzed in the present study. Preoperative assessment included physical examination, anorectal manometry, and anal endosonography. Appointments were scheduled every 6 months during the first and second year of treatment and every 2 years thereafter. Recurrence and incontinence were evaluated during each visit. Continence was assessed according to the Wexner continence grading scale. Anal manometry was performed 3 and 12 months after treatment and every 2 years thereafter. Anal endosonography was conducted 6 months after treatment. RESULTS Fistulas were classified as medium-high trans-sphincteric in 64 patients (91.42%) and were recurrent in 22 patients (32%). Before surgery, 22 patients (32%) reported fecal incontinence, which improved after surgery in 15 cases (70%), from 6.75 to 1.88 (P < 0.005) on the Wexner Scale. Eight preoperative continent patients (16.6%) reported postoperative incontinence (Wexner Score < 3), and 6 patients (8.5%) had recurrent incontinence. Among these patients, 2 developed recurrent incontinence 6 months after treatment, 2 developed recurrent incontinence 1 year after treatment, 1 developed recurrent incontinence 2 years after treatment, and 1 developed incontinence 5 years after treatment. CONCLUSIONS Fistulotomy with sphincter reconstruction is an effective technique for the treatment of complex fistula-in-ano. Continence and anal manometry results were improved in incontinent patients and were not jeopardized in continent ones. Fistulotomy with sphincter reconstruction is an especially suitable technique for incontinent patients with recurrent fistulas.

Abstract
BACKGROUND The ligation of intersphincteric fistula tract (LIFT) is a relatively new surgical technique for treating complex anorectal fistulas. METHODS LIFT was compared with anorectal advancement flap management (ARAF) of complex anorectal fistulas requiring previous seton drainage. Crohn's patients were excluded. Patients with no confirmed recurrent sepsis after 6 months were randomized to day surgery performance of LIFT (25; 17 male) or ARAF (14; 10 male) with removal of the seton. Outcome measures included recurrences, surgical time, complications, hospital readmissions, and fecal incontinence. RESULTS LIFT was 32.5 minutes shorter than ARAF (P < .001). Complications were similar, with no hospital readmissions. Return to normal activities was 1 week for LIFT patients, 2 weeks for ARAF patients (P = .016). At 19 months there were 3 recurrences (2 in the LIFT group). One ARAF patient had minor incontinence. CONCLUSIONS The LIFT procedure was simple, safe, shorter, and patients returned to work earlier. All patients had preliminary seton drainage, possibly contributing to the low recurrence rates.

Abstract
BACKGROUND Complex anal fistulas remain a challenge for the colorectal surgeon. The anal fistula plug has been developed as a simple treatment for fistula-in-ano. We present and evaluate our experience with the Surgisis anal fistula plug from two centres. METHODS Data were prospectively collected and analysed from consecutive patients undergoing insertion of a fistula plug between January 2007 and October 2009. Fistula plugs were inserted according to a standard protocol. Data collected included patient demographics, fistula characteristics and postoperative outcome. RESULTS Forty-four patients underwent insertion of 62 plugs (27 males, mean age 45.6 years), 25 of whom had prior fistula surgery. Mean follow-up was 10.5 months Twenty-two patients (50%) had successful healing following the insertion of plug with an overall success rate of 23 out of 62 plugs inserted (35%). Nineteen out of 29 patients healed following first-time plug placement, whereas repeated plug placement was successful in 3 out of 15 patients (20%; p = 0.0097). There was a statistically significant difference in the healing rate between patients who had one or less operations prior to plug insertion (i.e. simple fistulas) compared with patients who needed multiple operations (18 out of 24 patients vs. 4 out of 20 patients; p = 0.0007). CONCLUSIONS Success of treatment with the Surgisis anal fistula plug relies on the eradication of sepsis prior to plug placement. Plugs inserted into simple tracts have a higher success rate, and recurrent insertion of plugs following previous plug failure is less likely to be successful. We suggest the fistula plug should remain a first-line treatment for primary surgery and simple tracts.

Abstract
Perianal Crohn’s Disease (CD) is a significant cause of morbidity in CD patients. Accurate identification of perianal involvement requires advanced imaging techniques in addition to physical exam. Treatment of the disease is aimed at improving both the perianal and intestinal manifestations. Proper treatment depends upon the severity of the disease and combines current medical and surgical therapies to maximize response. The ability to improve perianal disease has grown significantly since the introduction of anti-TNF agents which are now a mainstay of treatment along with antibiotics and immunomodulators. New experimental therapies are limited by lack of research to support their use.

Abstract
Surgery for an anal fistula may result in recurrence or impairment of continence. The ideal treatment for an anal fistula should be associated with low recurrence rates, minimal incontinence and good quality of life. Because of the risk of a change in continence with conventional techniques, sphincter-preserving techniques for the management complex anal fistulae have been evaluated. First, the anal fistula plug is made of lyophilized porcine intestinal submucosa. The anal fistula plug is expected to provide a collagen scaffold to promote tissue in growth and fistula healing. Another addition to the sphincter-preserving options is the ligation of intersphincteric fistula tract procedure. This technique is based on the concept of secure closure of the internal opening and concomitant removal of infected cryptoglandular tissue in the intersphincteric plane. Recently, cell therapy for an anal fistula has been described. Adipose-derived stem cells have two biologic properties, namely, ability to suppress inflammation and differentiation potential. These properties are useful for the regeneration or the repair of damaged tissues. This article discusses the rationales for, the estimated efficacies of, and the limitations of new sphincter-preserving techniques for the treatment of anal fistulae.

Abstract
Background At present, transanal advancement flap repair (TAFR) is the treatment of choice for transsphincteric fistulas passing through the upper and middle third of the external anal sphincter. It has been suggested that epithelialization of the fistula tract contributes to the failure of the treatment. The aim of this study was to assess the prevalence of epithelialization of the fistula tract and to study its effect on the outcome of TAFR and TAFR combined with ligation of the intersphincteric fistula tract (LIFT). Methods Forty-four patients with a high transsphincteric fistula of cryptoglandular origin underwent TAFR. Nine of these patients underwent a combined procedure of TAFR with LIFT. In all patients the fistula tract was excised from the external opening up to the outer border of the external anal sphincter. In patients undergoing TAFR combined with LIFT an additional central part of the intersphincteric fistula tract was excised. A total of 53 specimens were submitted. Histopathological examination of the specimens was carried out by a pathologist, blinded for clinical data. Results Epithelialization of the distal and intersphincteric fistula tract was observed in only 25 and 22% of fistulas, respectively. There was no difference in outcome between fistulas with or without epithelialization. Conclusions Epithelialization of high transsphincteric fistulas is rare and does not affect the outcome of TAFR and TAFR combined with LIFT.
