Abstract
PURPOSE Currently, the anal fistula treatment which optimises healing and preserves bowel continence remains unclear. The aim of our study was to compare the relative efficacy of different surgical treatments for AF through a network meta-analysis. METHODS Systematic searches of MEDLINE, EMBASE and CENTRAL databases up to October 2022 identified randomised controlled trials (RCTs) comparing surgical treatments for anal fistulae. Fistulae were classified as simple (inter-sphincteric or low trans-sphincteric fistulae crossing less than 30% of the external anal sphincter (EAS)) and complex (high trans-sphincteric fistulae involving more than 30% of the EAS). Treatments evaluated in only one trial were excluded from the primary analyses to minimise bias. The primary outcomes were rates of success in achieving AF healing and bowel incontinence. RESULTS Fifty-two RCTs were included. Of the 14 treatments considered, there were no significant differences regarding short-term (6 months or less postoperatively) and long-term (more than 6 months postoperatively) success rates between any of the treatments in patients with both simple and complex anal fistula. Ligation of the inter-sphincteric fistula tract (LIFT) ranked best for minimising bowel incontinence in simple (99.1% of comparisons; 3 trials, n = 70 patients) and complex anal fistula (86.2% of comparisons; 3 trials, n = 102 patients). CONCLUSIONS There is insufficient evidence in existing RCTs to recommend one treatment over another regarding their short and long-term efficacy in successfully facilitating healing of both simple and complex anal fistulae. However, LIFT appears to be associated with the least impairment of bowel continence, irrespective of AF classification.

Abstract
Abstract
Background A common acquired anorectal condition is anal fistula. The treatment approaches that have been employed have been linked to erratic outcomes and sometimes life-threatening consequences. Video-assisted anal fistula treatment (VAAFT), a minimally invasive method, was introduced for adult patients in 2011.
Objective To know the efficacy of the VAAFT procedure in treating high anal fistulas and to compare it to open methods in the Basrah province.
Methods The present study was performed on 200 patients with high fistulas in ano in Basrah province. We divided the patients into 2 groups: Group A: treated by the VAAFT technique and Group B: treated by open fistulotomy
Results The patients treated with VAFFT revealed no occurrence of the following postoperative complication: Infection, incontinence, recurrence, anal stenosis, and bleeding. There was lower incidence of pain, short time for wound healing, rapid return to work, and more patient satisfaction compared with open fistulotomy
Conclusion An innovative method for managing ano fistula is VAAFT. Compared with traditional methods, it has a lot of benefits. It is day case surgeryno open wound.no damage to anal sphincter and no risk of incontinence, it is more affordable.it allow for clear identification of internal office, whole tract and its associated branches and cavity. The instrument can be used for multiple patients after good sterilization and disinfection.

Abstract
BACKGROUND Surgical management of anal fistulas in Crohn's disease (CD) is associated with high failure rates, and treatment options are limited due to ongoing proctitis, multiple tracts, and concern for incontinence and non-healing wounds. The aim of this study was to investigate the healing rate of ligation of the inters-sphincteric fistula tract (LIFT) for anal fistulas in Crohn's disease and identify prognostic factors for healing. METHODS This prospective analysis compared long-term healing rates of CD patients undergoing LIFT for anal fistulas. Consecutive patients with CD who underwent LIFT procedure at our institution, in the period from March 2012 to September 2019 were included. The main outcome was anal fistula healing rate. RESULTS The study cohort of 46 patients (mean age of 34.2 ± 13.0 years, 18 (40%) males). After a mean follow-up time of 33 ± 28 months, fistula healing was seen in 30 (65%) patients. A total of 8 patients were noted to have inter-sphincteric recurrence and 8 patients had trans-sphincteric recurrence. Smoking at the time of surgery was significantly associated with LIFT failure (HR 3.18, 95% CI 1.18-8.61, p = 0.02). Other factors, such as age, sex, race, disease duration and location, type of fistula history of proctitis, preoperatively use of biologics or a seton, and previous repair attempts, did not appear to influence LIFT healing. Although not statistically significant, there was a trend toward increase in failure among patients with active proctitis at the time of surgery (HR 1.97, 95% CI 0.71-5.42, p = 0.19). CONCLUSION Our increasing experience with LIFT for anal fistula in CD demonstrates a higher rate of healing (65%) than previously reported (48%). Smoking appears to negatively influence healing of LIFT in CD.

Abstract
BACKGROUND The treatment of anal fistula has been a conundrum for surgeons over the years. Various methods such as fistulotomy, fistulectomy, seton, ligation of the intersphincteric fistula tract (LIFT), advancement flaps, fibrin glue, and plugs are well-known techniques. Yet, they may be followed by several considerable complications, including incontinency and recurrence. METHODS In this study, the outcomes of the "Jump" and "Seton" techniques are compared. A randomized controlled trial consisting of 130 cases with cryptoglandular anal fistula randomly sorted into two groups was conducted. Group A underwent the "Jump technique" while group B underwent the "Seton technique." Outcomes, incontinency and recurrences in particular, were evaluated after a year of treatment. Data were analyzed by Fisher Exact, Chi-Square and Mann Whitney Tests. RESULTS Group A with 65 cases underwent the "Jump technique" while group B with 65 cases underwent the "Seton Method." Recurrence was reported in 12 (20%) cases in group A and 10 (15.6%) cases in group B (p=0.687). Overall incontinence was reported in 3 (4.6%) cases in group A and 18 (27.7%) cases in group B (P=0.001). The total St. Mark's scores for incontinency of group A (0.092±0.52) and group B (1.8±02.47) significantly differed (p<0.001). CONCLUSIONS The "Jump technique", named after a runner who jumped over hurdles, has obviated these complications. The "Jump technique" had satisfactory results and can be utilized as a first-line approach for all types of fistulas. Moreover, it can be redone for cases with recurrences without affecting the continence, paving the way to change the technique during operations.

Abstract
BACKGROUND Fistulotomy with immediate sphincteroplasty is a technique that can heal fistulas and decrease fecal incontinence more effectively than fistulotomy alone, in selected patients. OBJECTIVE We aimed to perform a long-term evaluation of fecal incontinence after fistulotomy and immediate sphincteroplasty in patients with complex anal fistula. DESIGN This prospective study included patients undergoing fistulotomy and immediate sphincteroplasty for complex anal fistula from January 2000 to December 2010. SETTINGS The study was conducted by 2 colorectal surgeons in the coloproctology unit of the General Hospital of Elche. PATIENTS We included patients aged ≥18 years with complex anal fistulas of cryptoglandular origin. MAIN OUTCOME MEASURES Main outcomes were recurrence and continence after fistulotomy and immediate sphincteroplasty, according to fistula tract height and preoperative continence status. RESULTS A total of 107 patients were included; 68.2% were men, with a mean age of 48 years and mean fistula duration of 12.8 months. The range and median follow-up period were 84 to 204 and 96 months. Thirty-seven fistulas were not primary. The overall healing rate was 84.1%. Primary fistulas healed by the end of follow-up in 58 (82.9%) of 70 patients; recurrent fistulas healed in 32 (86.5%) of 37; high tracts healed in 31 (83.8%) of 37, and nonhigh fistulas healed in 59 (84.3%) of 70. Male sex (OR = 0.66 (95% CI, 0.20-2.13); p > 0.05) and recurrent fistulas (OR = 0.43 (95% CI, 0.11-1.68); p > 0.05) could have a protective effect against postoperative fecal incontinence; however, more studies with larger sample sizes are necessary to confirm this result, whereas high fistulas showed a 4-fold increased risk of incontinence (range, 1.22-13.06; p < 0.01). One in 5 high-tracts patients experienced continence deterioration. LIMITATIONS This was a prospective study, and randomized clinical trials with more patients and longer follow-up are needed to compare fistulotomy and immediate sphincteroplasty with other sphincter-preserving techniques. CONCLUSIONS Fistulotomy and immediate sphincteroplasty are good options for treating complex anal fistulas, especially for recurrent fistulas, men, and patients with nonhigh tracts, with acceptable recurrence and incontinence rates.

EVALUACIN A LARGO PLAZO DE LA FISTULOTOMA Y LA ESFINTEROPLASTIA INMEDIATA COMO TRATAMIENTO PARA LA FSTULA ANAL COMPLEJA ANTECEDENTES:La fistulotomía y la esfinteroplastia inmediata es una técnica que puede curar las fístulas y disminuir la incontinencia fecal de manera más efectiva que la fistulotomía sola, en pacientes seleccionados.OBJETIVO:Nuestro objetivo fue realizar una evaluación a largo plazo de la incontinencia fecal después de la fistulotomía y la esfinteroplastia inmediata en pacientes con fístula anal compleja.DISEÑO:Este estudio prospectivo incluyó pacientes sometidos a fistulotomía y esfinteroplastia inmediata por fístula anal compleja, desde enero de 2000 hasta diciembre de 2010.ENTORNO CLINICO:El estudio fue realizado por dos cirujanos colorrectales de la Unidad de Coloproctología del Hospital General de Elche.PACIENTES:Se incluyeron pacientes ≥ 18 años con fístulas anales complejas de origen criptoglandular.PRINCIPALES MEDIDAS DE VALORACION:Los principales resultados fueron la recurrencia y la continencia después de la fistulotomía y la esfinteroplastia inmediata, de acuerdo con la altura del trayecto de la fístula y el estado de continencia preoperatoria.RESULTADOS:Se incluyeron un total de 107 pacientes; El 68,2% eran varones, con una edad media de 48 años y una duración media de la fístula de 12,8 meses. El rango y la mediana del período de seguimiento fue de 84-204 y 96 meses, respectivamente. Treinta y siete fístulas no fueron primarias. La tasa de curación general fue del 84,1%. Las fístulas primarias cicatrizaron al final del seguimiento en 58/70 (82,9%) pacientes; las fístulas recurrentes cicatrizaron en 32/37 (86,5%); los tractos altos cicatrizaron en 31/37 (83,8%) y las fístulas no altas cicatrizaron en 59/70 (84,3%). El sexo masculino (razón de posibilidades: 0,66 [0,20-2,13], p > 0,05) y las fístulas recurrentes (razón de posibilidades: 0,43 [0,11-1,68], p > 0,05) podrían tener un efecto protector contra la incontinencia fecal postoperatoria, sin embargo, más estudios con una muestra más grande son necesarios para confirmar este resultado. Fistulas altas mostraron un riesgo cuatro veces mayor de incontinencia ([1.22-13.06], p < 0.01). Uno de cada cinco pacientes con tractos altos experimentó un deterioro de la continencia.LIMITACIONES:Este fue un estudio prospectivo y se necesitan ensayos clínicos aleatorios con más pacientes y un seguimiento más prolongado para comparar la fistulotomía y la esfinteroplastia inmediata con otras técnicas de preservación del esfínter.CONCLUSIÓN:La fistulotomía y la esfinteroplastia inmediata son buenas opciones para el tratamiento de fístulas anales complejas, especialmente para fístulas recurrentes, varones y pacientes con tractos no altos, con tasas aceptables de recurrencia e incontinencia.

Abstract
The purpose of this study is to demonstrate that repetitive minor surgical procedures allow for a high rate of permanent closure of perianal fistulas in patients with Crohn’s disease (CD). Patients with perianal fistulizing CD (PFCD) who underwent perianal surgery at the University Hospital of Muenster between 2003 and 2018 were assessed for fistula characteristics and surgical procedures. We included 45 patients (m:f = 28:17) with a mean age of 27 years at first fistula appearance. Of these, 49% suffered from a complex fistula. An average of 4.2 (1–14) procedures were performed, abscess incisions and fistula seton drainages included. Draining setons were left in place for 5 (1–54) months, until fistula closure. Final surgical techniques were fistulotomy (31.1%), seton removal with sustained biological therapy (26.7%), Anal Fistula Plug (AFP) (17.8%), Over-The Scope-Clip proctology (OTSC) (11.1%), and mucosa advancement flap (4.4%). In 8.9% of cases, the seton was kept as permanent therapy. The time from first to last surgery was 18 (0–182) months and the median follow-up time after the last surgery was 90 (15–200) months. The recurrence rate was 15.5% after 45 (17–111) months. Recurrent fistulas healed after another 1.86 (1–2) surgical re-interventions. The final success rate was 80%. Despite biological treatment, PFCD management remains challenging. However, by repeating minor surgical interventions over a prolonged period of time, high permanent healing rates can be achieved.

Abstract
Abstract
Background High perianal fistula treatment remains challenging, mainly due to the variability in success and recurrence rates as well as continence impairment risks. So far, no procedure can be considered the gold standard for surgical treatment. Yet, strong efforts to identify effective and complication-free surgical options are ongoing. Fistulotomy can be considered the best perianal fistula treatment option, providing a perfect surgical field view, allowing direct access to the source of chronic inflammation. Controversy exists concerning the risk of continence impairment associated with fistulotomy. The present study aimed to assess the outcomes of fistulotomy with immediate sphincteric reconstruction regaring fistula recurrence, incontinence, and patient satisfaction.
Methods This interventional study was performed at the General Surgery Department of Zagazig University Hospital during the period from July 2018 to December 2019 on 24 patients with a clinical diagnosis of high transsphincteric fistula-in-ano. The fistulous tract was laid open over the probe placed in the tract. After the fistula tract had been laid open, the tract was curetted and examined for secondary extensions. Then, suturing muscles to muscles, including the internal and external sphincters, by transverse mattress sutures.
Results Our study showed that 2 patients develop incontinence to flatus ∼ 8.3%.and only one patient develop incontinence to loose stool, 4.2%. Complete healing was achieved in 83% and recurrence was 16.6%.
Conclusion Fistulotomy with immediate sphincteric reconstruction is considered to be an effective option in the management of high perianal fistula, with low morbidity and high healing rate with acceptable continence state.

Abstract
Background Surgical closure of anal fistulas with rectal advancement flaps is an established standard method, but it has a high degree of healing failure in some cases. The aim of this study was to identify risk factors for anal fistula healing failure after advancement flap placement between patients with cryptoglandular fistulas and patients with Crohn’s disease (CD). Methods From January 2010 to October 2020, 155 rectal advancement flaps (CD patients = 55, non-CD patients = 100) were performed. Patients were entered into a prospective database, and healing rates were retrospectively analysed. Results The median follow-up period was 189 days (95% CI: 109–269). The overall complication rate was 5.8%. The total healing rate for all rectal advancement flaps was 56%. CD patients were younger (33 vs. 43 years, p < 0.001), more often female (76% vs. 30%, p < 0.001), were administered more immunosuppressant medication (65% vs. 5%, p < 0.001), and had more rectovaginal fistulas (29% vs. 8%, p = 0.001) and more protective stomas (49% vs. 2%, p < 0.001) than patients without CD. However, no difference in healing rate was noted between patients with or without CD (47% vs. 60%, p = 0.088). Conclusions Patients with anal fistulas with and without Crohn’s disease exhibit the same healing rate. Although patients with CD display different patient-specific characteristics, no independent factors for the occurrence of anal fistula healing failure could be determined. Trial registration Not applicable due to the retrospective study design.

Abstract
AIM Complex perianal fistulas pose a challenge to the surgeon since the fistulous tract must be eliminated without impairing continence. Although without strong scientific evidence, some bibliography has demonstrated the efficacy of some sealants in the treatment of anal fistulas. We aimed to assess the feasibility and safety of calcium alginate hydrogel injections into the fistulous tract as treatment for trans-sphincteric cryptoglandular fistulas. METHODS A prospective, single-centre, case series of this novel technique was conducted in a level 3 Spanish hospital, including patients diagnosed with trans-sphincteric perianal fistulas and treated with a calcium alginate hydrogel sealant. A strict follow-up was performed by an independent surgeon at 1, 3, 6 and 12 months. The main outcome measures were feasibility, safety (number of adverse events) and efficacy of the treatment. RESULTS Twenty patients were treated. The treatment was performed for all patients. Seven adverse events related to the injection product or the surgical procedure were identified. After a 12-month follow-up, 12 patients were completely cured and eight were not cured, with a greater response in the first 6 months. These findings were confirmed by endoanal ultrasound, with a Cohen's kappa concordance rate of 0.89. No statistically significant differences were observed in pain measured using the visual analogue scale, faecal incontinence measured using the Wexner scoring system, and quality of life analysed by the SF-36 Health Survey. CONCLUSION The treatment was feasible, safe and with discrete satisfactory healing results. It also demonstrated an acceptable safety profile, without worsening of faecal incontinence, quality of life and pain following treatment.

Abstract
Abstract
Background Fistula-in-ano commonly affects males more than females. Some differences in the characteristics of fistula-in-ano between both genders have been recognized, yet the impact of these differences on the outcomes of surgery for fistula-in-ano is still unclear. The present study conducted a gender-specific analysis aiming to assess the characteristics and the outcomes of surgery of fistula-in-ano in each gender.
Patients and methods The records of patients with fistula-in-ano were retrospectively reviewed and the following variables were extracted: patients’ demographics, type of fistula-in-ano, position of the external opening, operation performed, incidence of recurrence and complications, particularly fecal incontinence. Gender-based analysis of the characters and outcomes of surgery for fistula-in-ano was performed.
Results 565 (491 males) patients of a mean age of 41.7 years were included. Females had a significantly higher percentage of low fistula-in-ano than males (70.2% vs. 50.3%, p = 0.002). Males had a significantly higher percentage of high trans-sphincteric fistula-in-ano (48.5% vs. 29.7%; p = 0.003). Anterior fistula-in-ano was more common in female patients (69% vs. 16.3%; p < 0.0001). Recurrence of fistula-in-ano was detected in 42 (7.4%) patients. Males had higher recurrence rate than females (7.9% vs. 4%; p = 0.34). Fecal incontinence developed in 1.7% of patients with higher incidence observed in females (4% vs. 1.4%).
Conclusion The majority of fistula-in-ano in males were posterior and high trans-sphincteric whereas most fistula-in-ano in females were low and anteriorly based. Despite the different characteristics of fistula-in-ano; no significant differences in the rates of fistula recurrence and fecal incontinence between males and females could be recorded.

Abstract
Abstract
Background Ligation of intersphincteric fistula tract technique is a new sphincter saving method with good results in management of anal fistula, but few studies report long-term follow-up data.
Material and methods This study investigated the use of ligation of intersphincteric fistula tract as a sphincter saving method based on long term results. This was a retrospective review of prospectively collected data. The study was conducted at two tertiary care university medical centers. 36 patients with complex fistula from January 2010 to January 2014 treated with classic ligation of intersphincteric fistula tract were retrospectively followed. Demographic data, previous repair attempts, the type of the fistula and score of fecal continence were collected. The procedure was performed by colorectal surgeons. Primary healing rate, failures and fecal incontinence score of patients were followed for 6–48 months.
Results A total of 36 patients underwent ligation of intersphincteric fistula tract during 24 months. The mean age of the patients was 35 years and 50% had two previous attempts at surgery. A total of 25 patients (69/5%) had high transsphincteric fistula. The mean follow up was 27 months. Successful fistula closure was achieved in 63/8% of the patients (23 of 36). The mean time of recurrence was 4.5 weeks. Only one (2/77%) patient reported gas incontinence (score: 3) after the procedure.
Conclusion The recurrence rate and fecal incontinence were measured. The ligation of intersphincteric fistula is a promising sphincter-preserving procedure that is simple and safe. Our study demonstrates favorable long-term results of ligation of intersphincteric fistula tract for management of complex anal fistulas.

Abstract
Abstract
Introduction Anal fistula is an epithelised path between the rectum or anal canal and the perianal region. The use of laparoscopic surgery with a minimally invasive procedure has led to the development of video-assisted surgical treatment of anal fistula.
Objective To describe the surgical technique VAAFT as a new approach to fistula.
Conclusion This is a safe and reproducible procedure. It enables the study of the entire fistula, obtaining the identification of accessory paths, cavitations and of the inner hole. More studies should be published for a better analysis of this technique, as well as to have a long-term outcome with new publications.

Abstract
Perianal Crohn's disease (CD) is a complex manifestation of CD that affects approximately 10% of patients. The spectrum of disease is quite variable, ranging from relatively mild disease to severe, aggressive manifestations that result in frequent hospitalizations, multiple surgeries, and poor quality of life. Despite significant recent advances in surgical and medical management, treatment remains challenging and frequently requires a multidisciplinary medical-surgical approach. The goal of this article is to review the current literature regarding the work-up, treatment, and future directions of therapy. Crucial features of effective management include the precise identification of manifestations, control of sepsis, limiting rectal inflammation, frequently with use of antitumor necrosis factor agents, and avoidance of extensive surgery.

Abstract
AIM To assess clinical healing in patients with perianal Crohn's disease with local intrafistular injection of autologous platelet-rich plasma. METHOD The pilot study was conducted at a single centre between January 2013 and December 2015. Autologous platelet-rich plasma was prepared in platelet-rich and platelet-poor fractions for local intrafistular injection in patients with proven, established perianal Crohn's disease. Patients were permitted biological therapies, and the Perianal Crohn's Disease Activity Index was recorded. Patients were followed for 48 weeks for clinical signs of healing (complete, partial or non-healing), monitoring fistula drainage, closure and epithelialization. RESULTS The study included 29 patients (19 males; mean age 38 ± 12.8 years) with four exclusions in the operating room because surgery was not indicated and four lost to follow-up. Five adverse events were recorded, with two requiring the drainage of abscess collections. Of the 21 patients assessable at 24 weeks, there was complete healing, partial healing and non-healing in 7 (33.3%), 8 (38.1%) and 6 (28.6%) patients, respectively. By 48 weeks, there was complete healing, partial healing and non-healing in 6 (40%), 6 (40%) and 3 (20%) patients, respectively, with a reduction in the number of visible external fistula openings at both time points (P = 0.021). By the end of the study, there was a higher trend of healing if biological therapies were continued (85.7% with biologics vs. 75% without, P = 0.527), but there were no statistically significant differences and no differences in the Perianal Crohn's Disease Activity Index. CONCLUSION Autologous platelet-rich plasma is safe in patients with perianal Crohn's disease, with an acceptable healing rate over a medium-term follow-up, particularly if biological therapies are used concomitantly.

Abstract
AIM Transanal flap is an attractive technique for complex fistulas. The aim of this study was to identify factors associated with poor outcome, recurrence and incontinence. METHOD All patients who underwent an advancement flap for the treatment of a complex anal fistula between 1995 and 2019 were prospectively enrolled. The patient data obtained included age, sex, body mass index, comorbid conditions and smoking history. The fistula characteristics analysed included previous anal surgery, anatomy of the fistula according to Park's classification, horseshoe or supralevator extension and preoperative seton drainage. The postoperative data registered included complications, postoperative stay, recurrence and incontinence. Predictive factors for recurrence and incontinence were identified using univariate and multivariate analysis. RESULTS One hundred and ninety patients were included; 134 (70.5%) were men and the mean patient age was 50 years. The median length of follow-up was 44.6 months. The fistula recurred in 14 patients (7.3%). Before surgery, 20 patients (10.5%) reported incontinence symptoms. In the continent patients a Wexner postoperative score of 0 was identified in 79.4%. Wexner scores between 1 and 3 were observed in 17% and scores of 4 or more in five patients (3%). Factors associated with recurrence included age < 50 years (OR = 4.8, P = 0.02, 95% CI 1.2-19), smoking (OR = 4.1, P = 0.03, 95% CI 1-16.5) and suprasphincteric fistula (OR = 0.5, P = 0.01, 95% CI 0.2-0.8) in multivariate log regression analysis. Major incontinence was influenced by female sex and previous anal surgery (OR = 7.5, P = 0.003, 95% CI 1.6-34 and OR = 0.1, P = 0.007, 95% CI 0.1-0.7, respectively). CONCLUSION Full-thickness transanal advancement flap is a good treatment for complex anal fistula repair. This study provides relevant information on risk factors for failure of therapy and incontinence, which can help in advising patients before surgery and planning a good treatment strategy.

Abstract
Crohn’s Disease (CD) is a chronic inflammatory disorder that potentially involves the entire gastrointestinal tract. Perianal fistulizing CD (pCD) is a serious and frequent complication associated with significant morbidities and a heavy negative impact on quality of life. The aim of CD treatment is to induce and maintain disease remission and to promote mucosal repair. Unfortunately, even the best therapeutic regimens in pCD do not have long-term efficacy and cause a significant number of side effects. Therefore, it is mandatory to study new therapeutical options such as the use of mesenchymal stromal cells (MSCs). These cells promote tissue repair via the induction of immunomodulation. The present review aims to analyze the existing updated scientific literature on MSCs adoption in the treatment of pCD to evaluate its efficacy and safety and to compare the use of bone marrow and adipose tissue derived MSCs, type of administration, and dose required for recovery.

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

Abstract
Fistulising perianal Crohn's disease (pCD) is an aggressive phenotype, and patients not only suffer from perianal manifestations but also a worsening course for their luminal disease. This article describes the 6 key steps clinicians need to consider when managing patients with pCD which include; (i) ensuring a prompt diagnosis, (ii) multi-disciplinary management, (iii) psychological support, (iv) using multimodal medical and surgical treatment strategies, (v) continually monitoring and optimising therapy and (vi) ensuring that patients have a way of accessing care if required. Patients with fistulising pCD often have an unpredictable disease course and complete remission can be elusive. As such, a considered and nuanced approach is essential keeping the wider multi-disciplinary team and the patient involved in all decision making.

Abstract
BACKGROUND Complex anal fistula in Crohn's disease (CD) poses a challenging problem. We sought to evaluate long-term surgical healing of complex anal fistula in CD through the two robust repair options-ligation of the intersphincteric fistula tract (LIFT) and advancement flap (AF). METHODS A single-center retrospective study was conducted evaluating long-term healing rates in patients with CD with complex anal fistula undergoing LIFT or AF in 2008-2018. Fistula healing was defined as closure of external wounds, cessation of drainage and absence of pain. Short-term and long-term healing rates were compared. Cox proportional hazards model was performed to identify independent predictors of fistula healing. RESULTS The study cohort included 60 CD patients undergoing LIFT (n = 38) or AF (n = 22). The AF group included 8 dermal flaps. Patients having LIFT were younger (35 years vs 43 years; p = 0.007), more likely to have a seton at the time of repair (92% vs 68%; p = 0.03) and less likely to have had prior repair attempts (34% vs 68%; p = 0.02). Short-term fistula healing occurred in 65% (n = 39) of the overall study cohort. However, at final follow-up, median 36 months (range 6-192 months), only 46% (n = 28) of repaired fistulas were healed. Considering the overall status of the cohort's perianal health at final follow-up, including both repaired, secondary or novel anal fistulas, only 50% (n = 30) of all patients in the cohort had all fistula sites healed and maintained bowel continuity at final follow-up. On Cox proportional hazards analysis, LIFT independently predicted long-term fistula healing (hazard ratio 2.3; 95% confidence interval 1.1-4.9; p = 0.03). Only a small number of patients (n = 5; 8%) required fecal diversion (n = 3) and/or proctectomy (n = 2). CONCLUSIONS Repair of complex anal fistula in CD results in modest healing rates. LIFT independently predicts long-term healing. However, these results must be taken in context, considering differences in patient and fistula characteristics between groups. These results ought to be kept in mind when counseling CD patients with complex anal fistula.

Abstract
BACKGROUND Complex perianal fistulas occurring in the absence of luminal inflammation (isolated perianal disease, IPD) may represent a specific phenotype of Crohn's disease (CD). AIM We assessed the effectiveness of tumor necrosis factor (TNF)-antagonists in patients with IPD compared to those with perianal CD (PCD) with luminal inflammation. METHODS Patients were identified through our institutional radiology database and were classified as PCD or IPD based on the presence or absence of luminal inflammation by ileocolonoscopy and abdominal enterography. Consecutive adults (> 17 years) with recurrent IPD who were treated with TNF antagonists were matched by age and gender to patients with complex PCD (1:2 ratio). Fistula remission was defined as an absence of fistula drainage. Surgery-free survival was assessed by Cox proportional hazard models. RESULTS Twenty-two patients with IPD treated with a TNF antagonist were compared with 44 matched patients with PCD. A similar proportion of patients with IPD and PCD were treated with concomitant immunomodulators (55% vs. 66%) and underwent examinations under anesthesia prior to therapy (36% vs. 46%). Fistula remission at 3, 6, and 12 months was lower for the IPD cohort: 9.5% versus 34%; 19% versus 39%; and 19% versus 43%. Surgical intervention after initiating anti-TNF therapy was more common for patients with IPD (HR 3.99: 95% CI, 1.62-9.83; p = 0.0026). CONCLUSIONS Fewer patients with IPD achieved fistula remission, and more required surgical intervention after anti-TNF therapy, suggesting that TNF antagonists may not be as effective in these patients.

Regusci L, Fasolini F, Meinero P, Caccia G, Ruggeri G, Serati M, Braga A. Video-Assisted Anal Fistula Treatment (VAAFT) for complex anorectal fistula: efficacy and risk factors for failure at 3-year follow-up. Tech Coloproctol 2020; 24:741-746. [PMID: 32318991 DOI: 10.1007/s10151-020-02213-w] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Accepted: 04/07/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND The aim of this study was to assess the 3-year objective and subjective outcomes of patients with complex anorectal fistula treated with Video-Assisted Anal Fistula Treatment (VAAFT). Furthermore, we evaluated the risk factors associated with recurrence. METHODS All consecutive patients with complex anorectal fistula who underwent VAAFT in Beata Vergine Hospital of Mendrisio, Switzerland, from January 2013 to January 2016, were enrolled. Patients with suspicion or diagnosis of Crohn's disease, malignancy, previous history of radiotherapy or radical pelvic surgery were excluded. Preoperative clinical assessment based upon medical history, physical examination and endosonography, was performed in all patients. Data regarding subjective outcomes (the Patient Global Impression of Improvement, patient satisfaction scores and Wexner score), objective cure rate (absence of fistula at clinical examination), and adverse events were collected during follow-up. Uni and multivariate analysis were performed to investigate outcomes. RESULTS One hundred and four patients had VAAFT. At 3-year follow-up, 96 patients (92.3%) were available for the evaluation. At 3 years after surgery, 81 of 96 patients (84.4%) declared themselves cured (p = 0.60). Similarly, at 3-year evaluation, 80 of 96 patients (83.3%) were objectively cured (p = 0.52). No serious intraoperative or postoperative complications were reported. All recurrences were treated with a repeat VAAFT procedure resulting in a complete healing. Uni and multivariate analysis of variables potentially involved in the failure of VAAFT showed that age ≥ 50 years was the only factor associated at risk of recurrence. CONCLUSIONS VAAFT is a highly effective safe procedure for the treatment of anorectal fistula, with a low recurrence rate at 3-year follow-up. However, our study demonstrated that age ≥ 50 years is a risk factor for failure of VAAFT.

Abstract
BACKGROUND The number of citations a scientific paper has received indicates its impact within any medical field. We performed a bibliometric analysis to highlight the key topics of the most frequently cited 100 articles on perianal fistula to determine the advances in this field. METHODS The Scopus database was searched from 1960 to 2018 using the search terms "perianal fistula" or "anal fistula" or "fistula in ano" or "anal fistulae" or "anorectal fistulae" including full articles. The topic, year of publication, publishing journal, country of origin, institution, and department of the first author were analyzed. RESULTS The median number of citations for the top 100 of 3431 eligible papers, ranked in order of the number of citations, was 100 (range: 65-811), and the number of citations per year was 7.5 (range: 3.8-40.1). The most-cited paper (by Parks et al in 1976; 811citations) focused on the classification of perianal fistula. The institution with the highest number of publications was St Mark's Hospital, London, UK. The most-studied topic was surgical management (n = 47). The country and the decade with the greatest number of publications in this field were the USA (n = 34) and the 2000s (n = 50), respectively. CONCLUSION The 100 most frequently cited manuscripts showed that surgical management had the greatest impact on the study of perianal fistula. This citation analysis provides a reference of what could be considered the most classic papers on perianal fistula, and may serve as a reference for researchers and clinicians as to what constitutes a citable paper in this field.

Abstract
The formation of an advancement rectal flap could be technically demanding in the presence of high perianal of rectovaginal fistula, and the outcomes could be frustrated by the inadequate view, bleeding and a poor exposure through the standard transanal approach. The application of the transanal minimally invasive surgery (TAMIS) to the advancement rectal flap procedure could overcome these difficulties. In the lithotomy position, a partial fistulectomy was performed and the internal opening was closed. A full-thickness flap was mobilized initially through the classic transanal approach. Subsequently, the TAMIS port was inserted and the mobilization of the flap was carried on proximally for as long as required. The laparoscopic visualization allowed a perfect view, a proper orientation of the flap and accurate hemostasis. The TAMIS-flap procedure seems a promising technique to perform a long advancement rectal flap to treat high perianal or rectovaginal fistulae (Video, Supplemental Digital Content 1, http://links.lww.com/SLE/A208).

Abstract
Perianal sepsis is a common condition ranging from acute abscess to chronic anal fistula. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. Surgery is the main treatment and several procedures have been developed, but the risks of recurrence and of impairment of continence still seem to be an unresolved issue. This statement reviews the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
Background Perianal fistulizing Crohn's disease is associated with severe symptoms such as pain, fecal incontinence, and a significant reduction in quality of life. Results In refractory cases, many patients face the decision of having a stoma and/or requiring proctectomy. In former years, the standard of care was a complete fistulectomy, bringing with it a high rate of continence disorders. Additionally, many patients received indefinite treatment, namely the placement of a seton to maintain surgical drainage. Conclusion More recently, newer biologics, cell-based therapies as well as novel surgical techniques have been introduced, raising new hopes that outcomes can be improved upon.

Abstract
PURPOSE OF REVIEW Perianal Crohn's disease is a morbid and disabling condition, notoriously difficult to successfully treat with conventional medical and surgical therapies. Mesenchymal stem cells (MSCs) are an emerging novel therapy for perianal Crohn's disease. RECENT FINDINGS Over 300 patients with perianal Crohn's disease have now been treated with MSCs in the context of clinical trials. All trials have demonstrated safety, and efficacy superior to conventional therapy with biologics and surgical intervention. This was consistent despite the heterogeneity in study protocols including variability in cell dosing, mode of delivery, repeat dosing, and allogeneic versus autologous donors. Sustained healing to 1 year has also been demonstrated in a recent extension of the largest phase III study confirming superior efficacy of MSCs to placebo at 1-year follow-up. However, several outstanding questions regarding the use of MSCs for perianal Crohn's disease remain, which, if answered, could enhance MSCs' treatment efficacy. These include defining the optimal MSC donor, optimal MSC source (e.g., bone marrow versus adipose tissue), investigating a potential alloimmune response following allogeneic cellular delivery, and determining the optimal mode for MSC delivery. In addition to these unanswered questions, significant challenges in the required infrastructure and cost required for cell-based therapies may drive future research toward identifying novel acellular therapies. SUMMARY Novel regenerative therapies offer promising new treatment options for perianal Crohn's disease, without the risk of opportunistic infection seen with biologics and incontinence with surgical techniques. Future research will help define the optimal MSC product and treatment protocol, and may even expand our horizon of regenerative medicine into acellular therapy as well as cell-based therapies.

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

Abstract
AIM Treatment of complex anal fistula (CAF) is challenging, often requiring multiple operations due to a high failure rate. The plethora of options attests to the lack of a panacea. Endorectal advancement flap (ERAF) carries the advantages of no sphincter division, no contour defect to the anal canal and no perineal wound. The failure rate of this procedure ranges between 15% and 60%. Although the procedure traditionally described a rhomboid (tongue-shaped) flap, an elliptical (curvilinear) flap was introduced to try to improve the results. This study aimed to describe the elliptical-shaped ERAF performed by the senior authors and others and compare failure rates between elliptical and rhomboid ERAFs for CAF. METHOD A retrospective review of all patients who underwent ERAF for CAF between 2011 and 2017 was undertaken. Patients were divided into two groups based on the type of flap: rhomboid or elliptical. The main outcomes measures were postoperative persistent or recurrent fistula. RESULTS Seventy-six ERAF procedures for CAF were identified in 71 patients; 39 had a classic rhomboid flap and 37 had an elliptical configuration with mean follow-up of 13.8 and 13.9 months, respectively. The groups were similar for demographic parameters and preoperative fistula characteristics. The overall failure rate was 37%, with a success rate of 64% in the rhomboid and 62% in the elliptical group. CONCLUSION The shape of the ERAF for treatment of CAF does not appear to influence failure rate.

Abstract
Anal fistulas are a common anorectal disease and are frequently associated with a perianal abscess. The etiology is based on a cryptoglandular infection in the intersphincteric space. Surgery remains the only definitive therapy. The primary goal of definitive fistula surgery is healing; however, success of fistula surgery is influenced by a variety of factors including the surgeon's experience, type of fistula, involvement of sphincter muscles, type of surgical procedure and patient-related factors. For the surgical treatment of a complex anal fistula, a variety of operative procedures have been described including fistulectomy with sphincterotomy, different flap procedures (e.g. mucosal flap and advancement flap) and finally so-called sphincter-preserving techniques, such as LIFT (ligation of intersphincteric fistula tract), VAAFT (video-assisted anal fistula treatment), the use of plugs of collagen or fibrin glue sealants as well as laser procedures or the clip. In the search for suitable quality indicators in anal fistula surgery there is a conflict between healing and preservation of continence. If potential quality indicators are identified the principles of anal fistula surgery must be adhered to and the appropriate selection of patients and procedures is of crucial importance to achieve high healing rates without compromising continence or inducing surgical revision due to abscesses or recurrence. Based on the available literature and guidelines, in the assessment of quality indicators considerable differences exist with respect to patient selection, etiology of anal fistulas and length of follow-up. Heterogeneity of treatment protocols lead to difficulties in a definitive assessment of which surgical treatment is the best option for complex anal fistulas.

Abstract
PURPOSE Mucosal advancement flap (MAF) is the best option for complex anal fistula (AF) treatment. Recurrence is not rare and the best surgical option for his handling is a challenge considering the incontinence risk and the healing rate. We aimed to determine the feasibility and outcomes of a second MAF for recurrent complex AF previously treated with mucosal advancement flap. METHODS We retrospectively identified 32 patients undergoing two or more MAF for recurrent AF in a larger cohort of 121 consecutive cases of MAF operated by the same senior colorectal surgeon. Only complex AF of cryptoglandular origin was enrolled. A long-term follow-up was performed collecting clinical and functional data. RESULTS Among 121 patients (group A) treated with mucosal advancement flap, 32 (26.4%) (group B) recurred with a complex AF requiring a second mucosal advancement flap procedure. Success rate of group B is 78.1%. Six patients of group B recurred a second time, another MAF was performed with healing in all cases. Complication rate (Clavien Dindo 3b) of group B is 9.4% compared to 8.3% of group A. A slight continence deficit (Miller score 1, 2, and 4) was detected after the first MAF in 3 patients. The Miller score for these patients did not change after the subsequent MAF. CONCLUSIONS MAF is effective for treatment of complex recurrent AF. A pre-existing MAF procedure does not worsen the healing rate of the second flap. The rate of surgical complications is similar with those reported in the literature for MAFs.

Abstract
AIM Rectal flap advancement is still a part of therapeutic management of anal fistulas. Data on the outcome of rectal flap advancement in patients with Crohn's disease (CD) is scarce. Our objective was to ascertain rates of failure of rectal flap advancement and to determine predictive factors for failure, with a special focus on CD METHOD: The patients' details, the characteristics of the fistula and the main clinical and therapeutic events were prospectively assessed among patients who underwent rectal flap advancement. All patients had a partial-thickness rectal flap advancement. Failure of primary rectal flap advancement was defined as the occurrence of at least one of the following: abscess, discharge, visible external opening, further drainage procedure. The rates of failure of rectal flap and the predictive factors of failure were assessed. RESULTS Eighty-seven patients (34 patients with CD) were included. The median (interquartile range) follow-up was 13.3 (3.8-38.1) months. The cumulative failure rates were 15.9% (10.3-23.6), 23.0% (16.0-31.8), 31.6% (22.9-41.8) and 41.3% (30.5-53.0) at 3, 6, 12 and 24 months respectively. These data were comparable in Crohn's patients. Those with a supralevator fistula [hazard ratio 2.53 (1.01-7.71), P = 0.0476] and patients who had fewer than two fistula drainages before rectal flap [hazard ratio 3.19 (1.40-8.23), P = 0.005] were associated with higher rectal flap failure rates. In CD patients, the absence of biological therapy at referral was predictive of failure. CONCLUSION Rectal flap advancement is a satisfactory option for the therapeutic management of anal fistula, including CD populations. Fistula drainage is needed before performing this surgical technique.

Abstract
BACKGROUND Rectal advancement flap is the standard surgical treatment for complex cryptoglandular anal fistulas, while Permacol™ collagen paste is considered an innovative treatment option for anorectal fistulas. This study aimed to compare the clinical outcomes of patients with complex cryptoglandular fistulas treated by endorectal advancement flap versus Permacol™ paste. METHODS This study was a retrospective analysis of patients with complex cryptoglandular anal fistulas. Thirty-one patients were treated with the rectal advancement flap (RAF group), while 21 were treated with Permacol™ paste injection (PP group). In PP group, the approach consisted of loose seton positioning followed several weeks later by closure internal opening with a resorbable sutures associated with paste injection into the fistula track. Clinical outcomes were assessed in terms of healing rate, faecal continence and patient satisfaction. RESULTS Seton drainage was done in all patients in both groups for a median duration of 8 weeks (range 4-18 weeks) before the final surgery (p = 0.719). No patient had faecal incontinence (CGS ≥ 5) preoperatively. Five patients (16%) in the RAF group and one (5%) in the PP group experienced faecal incontinence postoperatively. The 2-year disease-free survival was 65% in the RAF group and 52% in the PP group (p = 0.659). The median satisfaction scores were 5 (range 1-10) in the RAF group and 7 (range 2-10) in the PP group (p = 0.299). CONCLUSION The RAF appeared superior to PP in terms of fistula healing, although this result was not statistically significant. On the contrary, PP has a potential advantage in terms of continence disorders. Permacol™ paste can be considered as the initial treatment option for complex cryptoglandular anal fistulas in patients with faecal continence disorders.

Abstract
BACKGROUND Treatment of complex anal fistula (CAF) can be associated with high rates of recurrence and fecal incontinence (FI). Park suggested drainage of the affected intersphincteric anal gland for treatment of cryptoglandular anal fistula; however, recurrence after this technique was high. We modified the original Park's technique by extending the internal sphincterotomy to ensure adequate drainage of the intersphincteric space. The aim of this study was to evaluate the incidence of recurrence and FI after modified Park's technique in treatment of CAF. METHODS Adult patients of both genders with CAF were evaluated before undergoing modified Park's technique with Wexner continence score, clinical examination, and endoanal ultrasonography or MRI. Postoperatively, patients were examined every 2 wk until complete wound healing. The continence state was evaluated with Wexner continence score, and quality of life was assessed before surgery and at 6 mo postoperatively by Short Form-36 questionnaire. RESULTS Thirty-two patients (27 male) of a mean age of 38 y were included. Median follow-up was 12 mo. Two patients (6.25%) experienced recurrence and 5 (15.6%) developed complications. One patient (3.1%) developed new-onset FI postoperatively. Twenty-eight (87.5%) patients were completely satisfied with the procedure. Quality of life showed significant improvement at 6 mo postoperatively. CONCLUSIONS The modified Park's technique is a promising procedure for the treatment of CAF with low recurrence and FI rates, and improved quality of life.

Abstract
BACKGROUND Permacol paste injection is a novel treatment approach for complex cryptoglandular anal fistulas. This study was performed to evaluate the long-term clinical outcomes of treatment with Permacol paste for complex cryptoglandular fistulas. METHODS Patients with primary or recurrent complex cryptoglandular anal fistulas treated with Permacol paste from 2014 to 2016 were retrospectively analyzed. RESULTS A total of 46 patients (median age, 41.3 years; 21 female) underwent Permacol paste injection; 20 patients (43%) had previously undergone failed fistula surgery. The patients had experienced anal fistula-related symptoms for a median of 10 weeks (range, 3-50 weeks). All patients had a draining seton in situ for a median of 10 weeks (range, 4-46 weeks). The median follow-up time was 24 months (range, 1-25 months). At the 1-month follow-up, 2 patients had paste extrusion and 2 had anal abscesses. The mean preoperative Continence Grading Scale score was 1.10 ± 1.40, and that at 3 months postoperatively was 1.13 ± 1.39 ( P = .322). There was a significant difference in the preoperative and the 1- and 3-month postoperative pain scores ( P < .001). At the 24-month follow-up, the healing rate was 50% (n = 23). A total of 19 patients (41%) with a recurrent fistula after failed Permacol paste injection required additional operative procedures. The satisfaction rate at the 2-year follow-up was 65%. CONCLUSION Permacol paste injection is minimally invasive and technically easy to perform. It can be considered as a viable and reasonable option for the treatment of complex cryptoglandular anal fistulas in patients with fecal continence disorders.

Abstract
Aim To assess the results of the treatment of rectovaginal fistulas with incontinence and impaired anal tonus. Materials and Methods This study comprised three rectovaginal fistula groups that were treated using sphincteroplasty and fistulectomy: group 1: eight women with simple rectovaginal fistula due to birth trauma; group 2: six rectovaginal fistula cases that were associated with chronic inflammatory diseases; and group 3: five cases with at least one failed repair attempt. In the second step, operations that took place before the year 2000 were compared to the operations that took place after the year 2000 in terms of demographic and clinical characteristics. Results All of the simple rectovaginal fistula cases healed after the operation. Five of the group 2 patients healed after the operation. However, 1 patient with Crohn's disease needed to undergo reoperation, but successfully healed after 6 months. On the contrary, 3 patients in group 3 healed (60%) whereas 2 of them failed to heal. Clinical characteristics of the patients were different between the groups (before and after the year 2000). Conclusion The choice of operation must be done according to the patient's underlying pathology. Proper management of associated inflammatory diseases and systemic disorders is recommended for necessary complex cases.

Abstract
BACKGROUND There has been a surge in clinical trials studying the safety and efficacy of mesenchymal stem cells for the treatment of perianal Crohn's disease. OBJECTIVE The purpose of this work was to systematically review the literature to determine safety and efficacy of mesenchymal stem cells for the treatment of refractory perianal Crohn's disease. DATA SOURCES Sources included PubMed, Cochrane Library Central Register of Controlled Trials, and Embase. STUDY SELECTION Studies that reported safety and/or efficacy of mesenchymal stem cells for the treatment of perianal Crohn's disease were included. Two independent assessors reviewed eligible articles. INTERVENTION The study intervention was delivery of mesenchymal stem cells to treat perianal Crohn's disease. MAIN OUTCOMES MEASURES Safety and efficacy of mesenchymal stem cells used to treat perianal Crohn's disease were measured. RESULTS Eleven studies met the inclusion criteria and were included in the systematic review. Three trials with a comparison arm were included in the meta-analysis. There were no significant increases in adverse events (OR = 1.07 (95% CI, 0.61-1.89); p = 0.81) or serious adverse events (OR = 0.53 (95% CI, 0.28-0.98); p = 0.04) in patients treated with mesenchymal stem cells. Mesenchymal stem cells were associated with improved healing as compared with control subjects at primary end points of 6 to 24 weeks (OR = 3.06 (95% CI, 1.05-8.90); p = 0.04) and 24 to 52 weeks (OR = 2.37 (95% CI, 0.90-6.25); p = 0.08). LIMITATIONS The study was limited by its multiple centers and heterogeneity in the study inclusion criteria, mesenchymal stem cell origin, dose and frequency of delivery, use of scaffolding, and definition and time point of fistula healing. CONCLUSIONS Although there have been only 3 trials conducted with control arms, existing data demonstrate improved efficacy and no increase in adverse or serious adverse events with mesenchymal stem cells as compared with control subjects for the treatment of perianal Crohn's disease.

Abstract
AIM To describe the long-term outcomes of adipose-mesenchymal stem cells, platelet-rich plasma, and endorectal advancement flaps in patients with Perineal Crohn's Disease. METHOD This was a single-center, prospective, observational pilot study performed between March 2013 and December 2016. The study included adult patients diagnosed with Perianal Crohn's Disease (with complex perianal fistulas) refractory to previous surgical and/or biological treatment. Patients underwent surgical treatment in two stages. Stage 1: Fistula mapping, drainage, seton placement and lipoaspiration to obtain adipose-mesenchymal stem cells were performed. Stage 2: The setons were removed, and the fistula tract was debrided. A small endorectal advancement flap was created, with closure of the previous internal fistula opening. Then, 100-120 million adipose-mesenchymal stem cells mixed with platelet-rich plasma were injected into the internal fistula opening and fistula tract. RESULTS The study included nine patients (seven females), with a median age of 36 years (r = 23-57). Eleven fistula tracks were treated, of which, two were pouch-vaginal fistulas. The median follow-up period was 31 months (r=21-37). At the end of the follow-up period, 10/11 (91%) fistulas were completely healed and 1/11 (9%) was partially healed. At the end of this period, there was no evidence of fistula relapse or adverse reactions in any patients. The Perianal Disease Activity Index and Inflammatory Bowel Disease Questionnaire scores significantly improved after the procedure. CONCLUSION Combined therapy with adipose-mesenchymal stem cells, platelet-rich plasma and endorectal advancement flaps yielded good results in patients with refractory Perineal Crohn's Disease.

Abstract
BACKGROUND Fistula-in-ano has a reported incidence of 31-34%. Besides fistulotomy, options for fistula repair are seton placement, endorectal advancement flap (ERAF), fibrin sealant, anal fistula plug and ligation of the intersphincteric fistula tract. Despite having a reported success rate as high as 75-98%, ERAF is not without complications, including flap breakdown, recurrence and fecal incontinence. Traditionally, maintaining a broad base to preserve blood supply has been advocated to reduce flap failure. And the aim of the present study was to evaluate outcomes of adult patients who underwent ERAF for complex fistula-in-ano with the use of intraoperative fluorescence angiography (FA) at our institution between July 2014 and July 2016. METHODS We retrospectively reviewed consecutive cases of complex fistula-in-ano repair with ERAF and FA from a prospectively maintained dataset of adult patients with complex fistula-in-ano. Demographics, intraoperative data and 60-day outcomes were recorded and reviewed. RESULTS Six patients [five males and one female with a mean age of 40 years (range 25-46 years)], with a total of seven fistulas, were identified. Six (85.7%) of these patients had undergone prior surgery for fistula-in-ano. No recurrences or complications of any type were noted at 2-week and 8-week follow-up. The majority of patients (71.4%) required flap revision based on intraoperative FA prior to flap fixation. CONCLUSIONS FA is safe and offers real-time assessment of flap perfusion prior to and after fixation in anal fistula repair. The rate of flap ischemia may be underestimated, and therefore, to improve outcomes in ERAF, intraoperative FA should be included in the surgical armamentarium.

Abstract
Perianal Crohn's is a common manifestation of Crohn's disease. Primary manifestations of perianal disease mirror common anorectal conditions, however treatment is less successful than in those patients without Crohn's related perianal disease. A multimodal approach to therapy including medical and surgical modalities is often necessary. The goal of treatment is to manage symptoms while maintaining continence.

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
BACKGROUND Sphincter-sparing repairs are commonly used to treat anal fistulas with significant muscle involvement. OBJECTIVE The current study evaluates the trends and efficacy of sphincter-sparing repairs and determines risk factors for fistula recurrence. DESIGN AND SETTINGS A retrospective review was performed at 3 university-affiliated teaching hospitals. PATIENTS All 462 patients with cryptoglandular anal fistulas who underwent 573 sphincter-sparing repairs between 2005 and 2015 were included. Patients with Crohn's disease were excluded. MAIN OUTCOME MEASURES The primary outcome was the rate of fistula healing defined as cessation of drainage with closure of the external opening. Risk factors for nonhealing were also analyzed. RESULTS Five hundred three sphincter-sparing repairs were analyzed, whereas 70 were lost to follow-up. Two hundred twenty sphincter-sparing repairs (44%) resulted in healing, 283 (56%) resulted in nonhealing with a median follow-up of 9 (range, 1-125) months. The median time to fistula recurrence was 3 (range, 0-75) months with 79% and 91% of recurrences noted within 6 and 12 months. Patients treated with a dermal advancement flap, rectal advancement flap, or ligation of the intersphincteric tract procedure were less likely to have a recurrence than patients treated with a fistula plug or fibrin glue (p < 0.001). Over time, there was a significantly increased use of the ligation of the intersphincteric tract procedure (p < 0.001) and a significantly decreased use of fistula plugs and fibrin glue (p < 0.001); healing rates improved accordingly. There were no significant differences in healing rates with respect to patient demographics, comorbidities, or fistula characteristics. LIMITATIONS This study was limited by its retrospective design. CONCLUSIONS Healing rates following sphincter-sparing repairs of cryptoglandular anal fistulas are modest, but have improved over time with the use of better surgical techniques. In this study, ligation of the intersphincteric fistula tract and flaps were superior to fistula plugs and fibrin glue; the former procedures are therefore favored.

Abstract
Perianal Crohn's disease [CD] is found in a quarter of patients with CD and remains notoriously difficult to treat. Several medical and surgical therapies are available. However, none is particularly effective nor reliably provides sustained remission. In addition, surgical intervention is complicated by poor healing and the potential for incontinence. Mesenchymal stem cell-based therapies provide a promising treatment alternative for perianal CD, with demonstrated safety, improved efficacy, and a decreased side effect profile. Several phase I, II, and now III randomised controlled trials have now reported safety and efficacy in treating perianal CD. The aim of this review is to discusses the outcomes of conventional treatment approaches, outcomes of mesenchymal stem cell therapies, considerations specific to stem cell-based therapies, and future directions for research.

Abstract
BACKGROUND Ligation of intersphincteric fistula tract is a well-described sphincter-preserving technique for the management of fistula in ano. In 2007, we reported our early experience demonstrating a primary success rate of 94.4%. These findings have since been supported by several short-term studies, but long-term results and secondary cure rates after ligation of intersphincteric fistula tract failure remain unknown. OBJECTIVE This study aims to report a 10-year experience of ligation of intersphincteric fistula tract with extended long-term follow-up. DESIGN Retrospective analysis of single-center data from May 2006 to October 2010 was performed. SETTINGS This study was conducted at a large tertiary hospital in Bangkok, Thailand. PATIENTS All patients with primary or recurrent fistula in ano who underwent a ligation of intersphincteric fistula tract procedure were included. Patients with malignancy, incontinent patients, and patients with rectovaginal fistula were excluded. MAIN OUTCOME MEASURES Healing as defined by the absence of symptoms with no visible external opening on clinical examination. Follow-up was continued until May 2016. RESULTS In total, 251 patients were identified, with a primary healing rate of 87.65% at a median follow-up of 71 months. The healing rates for low transsphincteric, intersphincteric, high transsphincteric, semihorseshoe, and horseshoe fistulas were 92.1%, 85.2%, 60.0%, 89.0%, and 40.0%. Of the 42 patients who had an unhealed fistula after previous non-ligation of intersphincteric fistula tract surgery, 38 (90.48%) healed after the first attempt at ligation of intersphincteric fistula tract. There were 31 patients with unhealed fistulas after the first ligation of intersphincteric fistula tract. Of these, 3 healed spontaneously, and the rest underwent either repeat ligation of intersphincteric fistula tract, fistulotomy (if the recurrence was intersphincteric), or simple curettage (if no internal opening was found). Ultimately, only 2 of the original 251 patients remained unhealed, and there was no change in subjective continence status after surgery. LIMITATIONS This study was limited by its retrospective design. CONCLUSION Ligation of intersphincteric fistula tract is an effective technique for the treatment of fistula in ano, including recurrent or unhealed fistula after other procedures.

Abstract
Perianal disease is a common manifestation of Crohn disease (CD) that results in significant morbidity and decreased quality of life. Despite several medical and surgical options, complex perianal CD remains difficult to treat. Before the advent of biologic therapy, antibiotics were the mainstay of medical treatment. Infliximab remains the most well-studied medical therapy for perianal disease. Surgical interventions are limited by the risk of nonhealing wounds and potential incontinence. When treatment options fail, fecal diversion or proctectomy may be necessary. Stem cell therapies may offer improved results and seem to be safe, but are not yet widely used.
