Abstract
INTRODUCTION By searching relevant literature, the recurrence rate, complication rate after video-assisted anal fistula treatment (VAAFT), and efficacy and safety of the treatment were analyzed. EVIDENCE ACQUISITION Articles that reported the outcomes of VAAFT up to December 2020 were searched in PubMed (Medline) and Cochrane Library, in accordance with the preferred reporting items for systematic review and meta-analysis (PRISMA) screening guidelines. Two researchers independently completed the whole process from screening and inclusion to quality evaluation and bias risk assessment, and the data was included in the RevMan 5.3 software for analysis. The main outcomes were demographic data of patients, detection rate, classification of internal opening of anorectal fistula, postoperative recurrence rate, and incidence of complications. EVIDENCE SYNTHESIS A total of 10 articles were included (779 patients). The average age of the patients was 44 years old, average operation time was 60 min, and the average follow-up time was 22 months. The ratio of male to female was 2.4:1, the ratio of high anorectal fistula to low anorectal fistula was 6.6:1, the detection rate of internal openings was 98%, the weighted recurrence rate was 24%, and the weighted complication rate was 1%. CONCLUSIONS VAAFT is effective and safe in the treatment of anorectal fistulas.

Surgical treatment trends and outcomes for anal fistula: fistulotomy is still accurate and safe. Results from a nationwide observational study. Tech Coloproctol 2023; 27:909-919. [PMID: 37460829 DOI: 10.1007/s10151-023-02842-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 04/25/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE The aim of the present study was to analyse current surgical treatment preferences for anal fistula (AF) and its subtypes and nationwide results in terms of success and complications. METHODS A retrospective multicentre observational cohort study was conducted. The study period was 1 year (2019), with a follow-up period of at least 1 year. A descriptive analysis of patient characteristics and trends regarding technical options was performed. Univariate and multivariate Cox regression models were used to analyse factors associated with healing and faecal incontinence (FI). RESULTS Fifty-one hospitals were involved, providing data on 1628 patients with AF. At a median follow-up of 18.3 (9.9-28.3) months, 1231 (75.9%) patients achieved healing, while 390 (24.1%) did not; failure was catalogued as persistence in 279 (17.2.0%) patients and as recurrence in 111 (6.8%). On multivariate analysis, factors associated with healing were fistulotomy (OR 5.5; 95% CI 3.8-7.9; p < 0.001), simple fistula (OR 2.1; 95% CI 1.5-2.8; p < 0.001), single tract (HR 1.9; 95% CI 1.3-2.8; p < 0.001) and number of preparatory surgeries (none vs. 3; HR 1.8; 95% CI 1.2-2.8; p = 0.006). Regarding de novo FI, in the multivariate analysis previous anal surgery (OR 1.5, 95% CI 1.0-2.4, p = 0.037), age (OR 1.02, 95% CI 1.00-1.04, p = 0.002) and being female (OR 1.7, 95% CI 1.1-2.5, p = 0.008) were statistically related. CONCLUSIONS Anal fistulotomy is the most used procedure for AF, especially for simple AF, with a favourable overall balance between healing and continence impairment. Sphincter-sparing or minimally invasive sphincter-sparing techniques resulted in lower rates of healing. In spite of their intended sphincter-sparing design, a certain degree of FI was observed for several of these techniques.

Abstract
Perianal fistulizing Crohn's disease (CD) represents a severe phenotype of CD that is associated with significant morbidity and reduction in quality of life. Perianal fistulizing CD is caused by a complex interplay of genetic predisposition, immune dysregulation, gut dysbiosis, and various unknown physiological and mechanical factors. A multidisciplinary approach is hence required for optimal management . A detailed anatomical description and classification of perianal fistula, including comprehensive clinical, endoscopic, and radiological diagnostic workup, is an important prerequisite to treatment. For simple perianal fistulas, use of antibiotics and immunomodulators, with or without fistulotomy, are appropriate measures. The medical management of complex perianal fistula, on the other hand, requires adequate control of infection before initiation of therapy with immunomodulators. In active complex perianal fistula, anti-tumor necrosis factors remain the most accepted therapy, with concomitant use of antibiotics or immunomodulators enhancing the efficacy. For patients refractory to anti-tumor necrosis factors, treatment with anti-integrins, anti-interleukins, and small molecules is being evaluated. Mesenchymal stem cells, hyperbaric oxygen therapy, and exclusive enteral nutrition have also been investigated as adjunct therapies. Despite the expansion of the medical armamentarium, a large proportion of the patients require surgical interventions. In this review, we provide an up-to-date overview of the pathophysiology, clinical presentation, diagnosis, and medical management of perianal fistulizing CD. A brief overview of the surgical management of perianal fistulizing CD is also provided.

[PMID: 37041156 PMCID: PMC10090040 DOI: 10.1038/s41598-023-32698-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 03/31/2023] [Indexed: 04/13/2023] Open
Abstract
The aim of this study was to introduce a new technique, the bared external anal sphincter technique, and to evaluate its effectiveness and safety for primary or recurrent high horseshoe anal fistula (HHAF). We used data from a tertiary referral hospital's prospective database of a hospital-based cohort. All the patients underwent the bared external anal sphincter procedure. The main outcomes were short-term clinical outcomes including the 6-month cure rate, Visual Analog Scale pain score (VAS-PS) and Cleveland Clinic Florida incontinence score (CCF-IS). The secondary outcomes included the Quality of Life in Patients with Anal Fistula Questionnaire score (QoLAF-QS), Bristol stool chart and postoperative complications. A total of 48 HHAF patients (39 males) with a mean age of 34.2 years (SD 9.04; range, 21-54) were analyzed in this retrospective study. At the 6-month follow-up, the average VAS-PS and CCF-IS were 0.81 (SD 2.28; range, 0-10) and 1.29 (SD 2.87; range, 0-13), respectively. QoLAF-QS showed that the bared external anal sphincter procedure had no impact over their quality of life in 45 patients (93.75%), limited impact in 2 patients (4.16%), and moderate impact in one patient (2.08%). The Bristol stool scale showed that all patients had normal stool characteristics. The 6-month cure rate was 93.75%. Three patients (6.25%) experienced recurrent symptoms but recovered after surgical management. Urinary retention occurred in 1 case (2.78%). No other postoperative complications were reported. No patient had anal incontinence. The bared external anal sphincter procedure is a safe, effective and sphincter-sparing approach for patients with primary or recurrent HHAF in terms of short-term results.

Abstract
BACKGROUND Video-assisted anal fistula treatment (VAAFT) has gained increasing acceptance as a sphincter-sparing procedure for treating complex anorectal fistulas (CAF), but no unequivocal conclusions can yet be drawn regarding its ultimate effectiveness. We reviewed the literature and performed a meta-analysis to evaluate the efficacy and safety of VAAFT in CAF patients. METHODS The study protocol was registered with the PROSPERO database (CRD42021279085). A systematic literature search was performed in the PubMed, Embase, and Cochrane Library databases up to June 2021 with no restriction on language based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We used the keywords video-assisted surgery, video-assisted anal fistula treatment, and complex anorectal fistula to identify relevant studies. RESULTS Fourteen trials (7 prospective and 7 retrospective) with a total of 1201 patients (mean age 43.5 years) were included. The median follow-up duration was 16.5(8-48) months. Pooled analysis showed that the rates of success, recurrence and postoperative complication across the studies were 83% (95% CI 81-85%, I2 = 37.9%), 16% (95% CI 14-18%, I2 = 4.8%), 11% (95% CI 7-15%, I2 = 72.1%), respectively. The postoperative Jorge-Wexner score used to assess the level of anal incontinence was 1.09 (95% CI, 0.9-1.27, I2 = 74.6%). The internal opening detection rate was 97.6% (95% CI 96.1-99.6%, I2 = 48.2%). Recurrence rates varied according to the closure method of internal opening from 21.4% after using staplers, 18.7% after suturing, to 23.5% after advancement flap. The hospital stay was 3.15 days (95% CI 2.96-3.35, I2 = 49.7%). Subgroup analysis indicated that the risk of heterogeneity in the urine retention group was higher compared with that of the overall group and that retrospective studies may be the source of heterogeneity for postoperative anal incontinence. r . Sensitivity analysis confirmed the stability of the pooled results. Begg's and Egger's tests showed no evidence of publication bias. CONCLUSIONS According to the available evidence, VAAFT may be a valuable alternative to fistulotomy or seton in treating CAF and has the additional long-term benefits of reducing anal incontinence and surgical morbidity, permitting earlier healing and accelerated rehabilitation.

Abstract
BACKGROUND Anal fistulae are difficult to treat entities and minimally invasive procedures are evolving with promises. Our improvised technique is a simple and easy day-care procedure for simple fistulae. AIM To evaluate the outcomes of a technical modification in the procedure of core-cut fistulectomy in simple cryptoglandular fistula-in-ano. METHODS 47 patients of fistula-in-ano presenting to the out-patient of the General Surgery department at All India Institute of Medical Sciences, Bhopal, from November 2018 to March 2020 were selected. A complete history, physical examination followed by relevant investigations were meticulously performed and recorded. They were operated using an improvised core-cut technique, under a pudendal nerve block. Patients were kept on follow-up for a minimum of 6 months period to note the outcome of the surgery. RESULTS The mean age was 37 ± 13.17 years with a male: female ratio of 5.1:1. The most common clinical presentation was perianal discharge in 96% of patients followed by pain and pruritus ani in 45% and 32%, respectively. 93.62% were inter-sphincteric, and 6.38% were trans-sphincteric. Extra-sphincteric and supra-levator fistulae were excluded from the study. The mean operative time was 17 ± 10.19 minutes. The mean healing time was 19.21 ± 5.99 days. The success rate of this novel technique of core-cut was calculated to be 89.37%. The rate of recurrence was calculated to be 10.63% (5 out of 47 patients). None of our patients developed incontinence. CONCLUSION Our pilot study results for simple fistulae-in-ano had less morbidity, postoperative pain, better wound healing, patient satisfaction, and compliance with low risk of recurrence, and no incontinence. It could hence be recommended for larger groups and more complicated fistulae in the future.

Abstract
Fistula laser closure (FiLaC) is a relatively new sphincter-sparing technique in fistula surgery that was initially reported in 2011. It involves the radial dissipation of laser energy in the fistula tract and, through a combination of coagulation and shrinkage of the tract, is proposed to result in progressive sealing of fistulas. Early studies have suggested minimal impact on continence and touted the advantage of minimal morbidity with potential of repeat procedures if the technique fails initially. Despite early promising results, ten years on, questions remain on the technique, patient selection and long-term outcomes. This narrative review assesses the evidence reported to-date of radially emitting laser fistula surgery in the treatment of perianal fistulas.

Risk factors for postoperative recurrence of anal fistula identified by an international, evidence-based Delphi consultation survey of surgical specialists. Int J Surg 2021; 92:106038. [PMID: 34339882 DOI: 10.1016/j.ijsu.2021.106038] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 06/10/2021] [Accepted: 07/16/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Despite the emerging knowledge about postoperative anal fistula recurrence (AFR) and the increasing number of clinical studies, there is no better understanding or consensus regarding the risk factors for AFR. The aim of this study was to generate international consensus guidance statements focusing on AFR. METHODS A two-round modified Delphi process was conducted among international surgical specialists via an online survey delivered by email with a secure link created with Google Forms. Surgeons were asked to use a 9-point Likert scale to rate the importance of patient-, fistula-, and surgery-related statements developed based on our previous systematic review. Consensus was reached when at least 70% of panel members rated a statement as being of critical importance (ratings of 7-9). RESULTS Of a total of 60 experts invited, 38 experts representing 13 countries from four continents agreed to participate in the first round of the Delphi process and 31 in the second round. In total, consensus was reached on 14 statements on the risk factors for AFR in three domains: patient-related risk factors included comorbid colitis, inflammatory bowel disease and use of immunosuppressants; fistula-related factors included transsphincteric fistula, number of fistula, horseshoe extension, undetected internal opening, location of anal fistula, recurrent fistula, suprasphincteric fistula, and height of the internal opening; and surgery-related factors included type of surgery, previous fistula surgery and surgeon. CONCLUSION This Delphi study provides an evidence-based profile of risk factors for AFR in the patient-, surgery- and fistula-related domains from a global perspective. Clinically, these indicators can be incorporated to develop risk calculation tools for the early detection of AFR in high-risk patients, allowing early prevention and intervention.

Abstract
BACKGROUND Therapeutic options for complex anal fistula (CAF) are limited. Video-assisted anal fistula treatment (VAAFT) allows examination of these anatomically complex fistulae from within. The aim of the present study was to evaluate outcomes of VAAFT for a series of CAF. METHODS A retrospective study was conducted on consecutive patients at a single centre with complex anal cryptoglandular and Crohn's fistulae managed with VAAFT from June 2016 to June 2019. CAF was diagnosed as high intersphincteric/transsphincteric tract, multiple/secondary tracts, horseshoe or anovaginal fistulae. Patients were treated with 'therapeutic intent' if the internal opening was closed at the time of ablation and 'diagnostic/staged/palliative' VAAFT if there was no ablation/partial treatment/ablation-only, respectively. Symptom improvement was a reduction in reported pain, discharge, or pad use. RESULTS Eighty-four patients (73 cryptoglandular, 11 Crohn's, M:F 2.5:1, median age 43 [22-77] years), underwent 105 VAAFT procedures. Twenty patients had > 1 VAAFT. Median follow-up was 8 (1-46) months. 40 (48%) had multiple or secondary tracts; an additional 16 (19%) had horseshoe and 3 (4%) anovaginal fistulae. Of the 84 patients, 19 [16/73 (22%) cryptoglandular and 3/11 (27%) Crohn's fistulae] healed. 34 (40%) unhealed reported improved symptoms; 23 (27%) no improvement; and 6 (7%) were worse. Sixteen (19%) had CAF > 5 years of whom none healed, albeit 50% reported symptom improvement. Five patients (6%) developed faecal incontinence: 2 temporary, 1 to flatus only and 1 to liquid and 1 to solid, all managed conservatively. CONCLUSIONS VAAFT is a useful minimally invasive procedure for complex fistula with no other minimally invasive options. Complete healing is rare, and, although symptoms can be improved in a number of cases, there is a small risk of incontinence.

Abstract
Pilonidal disease (PD) is a common condition, and there is still an ongoing debate on ideal management that should be minimally invasive, safe, and efficient. The use of radially emitting laser in the treatment of chronic PD is a novel minimally invasive technique, and initial studies with a small number of patients showed promising results. This study aimed to assess the efficacy and safety of chronic PD treatment with a laser using a systematic review of the published literature. A systematic review was conducted after PubMed, Scopus, Embase, Web of Science, and the Cochrane database search for studies reporting laser treatment of chronic PD. Also, our unpublished prospective single-center study was included in this review. Ten of 87 studies were eligible for the review, including 971 patients. The median age of the patients was 26 (range 13-68), and the median operative time was 26 (range 6-65) min. With a median follow-up of 12 (range 7-25) months, 917 (94.4%) patients achieved primary healing with a weighted mean recurrence rate of 3.8%. The weighted mean complication rate was 10% (95% CI 5.7-14.3%, I2 = 82.28, p < 0.001), and all were minor. The published literature demonstrates that laser treatment is a promising procedure in the management of chronic PD. Furthermore, the review showed that standardized operative techniques and perioperative steps were used. The results were limited to the mild chronic PD. Classification of PD severity and standardized outcome reporting is required to define indications and contraindications for laser PD treatment. Randomized controlled trials are needed to determine the long-term effectiveness and superiority of laser treatment over other methods.

Abstract
BACKGROUND Management of cryptoglandular fistula-in-ano (FIA) can be challenging. Despite Dutch and international guidelines determining optimal therapy is still quite difficult. The aim of this study was to report current practices in the management of cryptoglandular FIA among gastrointestinal surgeons in the Netherlands. METHODS Dutch surgeons and residents who are treating FIA regularly were sent a survey invitation by email. The survey was available online from September 19 to December 1 2019. The questionnaire consisted of 28 questions concerning diagnostic and surgical techniques in the treatment of intersphincteric and transsphincteric FIA. RESULTS In total, 147 (43%) surgeons responded and completed the survey. Magnetic resonance imaging was the preferred diagnostic imaging modality (97%) followed by the endo-anal ultrasound (12%). In case of a high FIA, 86% used a non-cutting seton. Most respondents removed a seton between 6 weeks and 3 months (n = 84, 58%). Fistulotomy was the procedure of preference in low transsphincteric (86%) and low intersphincteric FIA (92%). Mucosal advancement flap (MAF) and ligation of intersphincteric fistula tract (LIFT), with 78% and 46%, respectively, were the procedures that were applied most often in high transsphincteric FIA. In high intersphincteric FIA 67% performed a MAF and 33% a fistulotomy. Thirty-three percent of all respondents stated that they habitually closed the internal fistula opening, half of them used a Z-plasty. For debridement of the fistula tract the preferred method was curettage (78%). CONCLUSIONS Dutch gastrointestinal surgeons use various techniques in the management of FIA. Novel promising techniques should be investigated adequately in sufficient large trials to increase consensus. A core outcome measurement and a prospective international database would help in comparing results. Until then, treatment should be adjusted to the individual patient, governed by fistula characteristics and patient choice.

Abstract
Introduction. Complex anal fistula (CAF) is a challenging anorectal condition. Although numerous treatments for its management have been proposed, none is ideal. Herein, we investigated the clinical efficacy of video-assisted modified ligation of the intersphincteric fistula tract (LIFT) in comparison with the incision-thread-drawing procedure for Parks type II anal fistulas. Methods. Male and female adult patients with Parks type II anal fistula who were randomized to receive one of two procedures in the Anorectal Surgery Unit of the Affiliated People's Hospital of Ningbo University: video-assisted modified LIFT (test group, 30 cases) or incision thread drawing (control group, 30 cases). Healing and recurrence, postoperative pain, and postoperative autonomous anal control ability were compared. Results. In the test group, the pain scores were significantly lower (P = .001) and wound healing was faster (P = .001). However, there were no marked differences between groups in operative efficacy or postoperative infection rate (all P > .05). We followed all the patients for more than 18 months, with the test group having lower Jorge-Wexner incontinence (P = .005) and fecal incontinence (FI) severity index (P = .000) scores. No significant difference in recurrence (χ2 = .351, P = .554) or healing (χ2 = 1.071, P = .301) rate was found between the 2 groups. Conclusions. We established that video-assisted modified LIFT is superior in repairing Parks type II anal fistulas, with less trauma, quicker recovery, and better anal function.

Abstract
AIM Fistula Laser Closure (FiLaC™) is a novel sphincter-preserving technique that is based on new technologies and shows promising results in repairing anal fistulas whilst maintaining external sphincter function. The aim of the present meta-analysis is to present the efficacy and the safety of FiLaC™ in the management of anal fistula disease. METHOD The present proportional meta-analysis was designed using the PRISMA and AMSTAR guidelines. We searched MEDLINE, Scopus, clinicaltrials.gov, Embase, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar databases from inception until November 2019. RESULTS Overall, eight studies were included that recruited 476 patients. The pooled success rate of the technique was 63% (95% CI 50%-75%). The pooled complication rate was 8% (95% CI 1%-18%). Sixty-six per cent of patients had a transsphincteric fistula and 60% had undergone a previous surgical intervention, mainly the insertion of a seton (54%). The majority had a cryptoglandular fistula. Operation time and follow-up period were described for each study. CONCLUSION FiLaC™ seems to be an efficient therapeutic option for perianal fistula disease with an adequate level of safety that preserves quality of life. Nevertheless, randomized trials need to be designed to compare FiLaC™ with other procedures for the management of anal fistulas such as ligation of intersphincteric fistula tract, anal advancement flaps, fibrin glue, collagen paste, autologous adipose tissue, fistula plug and video-assisted anal fistula treatment.

Abstract
Anal fistulae can be a very difficult disease to manage. The management of complex fistulae is even more challenging. The risk to the fecal continence mechanism due to damage to the anal sphincters and refractoriness to the treatment (high recurrence rate) pose the two biggest challenges in the management of this disease. Apart from these, there are several other challenges in the treatment of complex fistulae. The intriguing and uphill task is that satisfactory solutions to most of these challenges are still not known, and there is hardly any consensus on whatever treatment solutions are available. To summarize, there is no gold-standard treatment available for treating complex anal fistulae, and the search for a satisfactory treatment option is still on. In this review, the endeavor has been to discuss and highlight recent path-breaking updates in the management of complex anal fistulae.

Abstract
Background To explore the efficacy of video-assisted anal fistula treatment (VAAFT) combined with an internal-opening closure technique using a stapler in the treatment of Parks II anal fistula. Methods From September 2017 to June 2019, 75 patients with Parks II anal fistulas in Beijing Erlonglu Hospital were enrolled and randomly allocated into two groups. The 37 patients in the treatment group received VAAFT combined with internal-opening closure techniques, and the 38 patients in the control group were treated with anal fistulotomy with seton placement. The primary outcomes included the healing rate and recurrence, the fecal incontinence severity index (FISI) score, and the Wexner incontinence score during the 6-month postoperative follow-up. Results Thirty-two cases were healed in the treatment group (86.5%) and thirty-six cases were cured in the control group (94.7%). There was no notable difference in the healing rate between the two groups (P=0.487). Significant differences between the groups were observed in the Wexner incontinence and FISI scores at 1, 3, and 6 months after the operation (P=0.001). Furthermore, the wound healing time in the treatment group was significantly shorter than in the control group (P<0.05), while the numerical rating scale (NRS) for postoperative pain on the first day and 1 week after the operation were significantly lower in the treatment group than in the control group (P<0.05). Conclusions VAAFT combined with closure of the internal opening using a stapler is effective and safe for Parks II anal fistula, and should be promoted as a promising treatment.

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
The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a position statement of Italian colorectal surgeons to address the surgical aspects of Crohn's disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the surgical treatment of Crohn's disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Abstract
BACKGROUND Ligation of the intersphincteric fistula tract is a sphincter-preserving technique for the treatment of anal fistulas. The BioLIFT modification involves the placement of a biologic mesh in the intersphincteric plane. Advocates of this modification state improved healing rates, however evidence for this is lacking, and this approach costs significantly more. OBJECTIVE The purpose of this study was to compare the healing rates of the ligation of the intersphincteric fistula tract with the BioLIFT. DESIGN This was a retrospective cohort study. SETTINGS The study was conducted at a tertiary care hospital from April 2008 to April 2018. PATIENTS All adult patients with transsphincteric anal fistulas were included. Patients were excluded if they had IBD, more than 1 fistula tract operated on simultaneously, or a previous attempt at repair. MAIN OUTCOME MEASURES The primary outcome was primary healing of the fistula tract, and secondary outcomes included overall success, complications, and time to recurrence. RESULTS There were 119 cases (75 ligation of the intersphincteric fistula tract and 44 BioLIFTs). One surgeon performed 84% of the BioLIFT cases. The primary healing rate was 75.0% versus 58.7% (p = 0.08), and the complication rate was 22.7% versus 17.3% (p = 0.48; BioLIFT vs ligation of intersphincteric fistula tract). After multivariate logistic regression, the BioLIFT had a significantly better healing rate (OR = 2.38 (95% CI, 1.01-5.62); p = 0.048). Median follow-up was 9 versus 29 weeks (BioLIFT vs ligation of intersphincteric fistula tract). Kaplan-Meier analysis demonstrated no difference in the time to recurrence (p = 0.48). LIMITATIONS This study was limited by the retrospective nature, different lengths of follow-up, and varying case numbers between the surgeons. CONCLUSIONS The BioLIFT modification is safe and effective for the treatment of anal fistulas but has a higher cost. This modification warrants additional prospective studies to establish its benefits over the ligation of the intersphincteric fistula tract procedure.

La modificación BioLIFT implica la colocación de una malla biológica en el plano interesfintérico. Protagonistas de la modificación mejoraron las tasas de curación, sin embargo, carecen evidencias definitivas y la técnica eleva costos significativamente.Comparar las tasas de curación de ligadura del tracto de la fístula interesfintérica con el BioLIFT.Estudio de cohorte retrospectivo.Hospital de atención de tercer nivel desde abril de 2008 hasta abril de 2018.Se incluyeron todos los pacientes adultos con fístulas anales transfinteréricas. Los pacientes fueron excluidos si tenían enfermedad inflamatoria intestinal, más de un tracto fistuloso operado simultáneamente o con un intento previo de reparación.El resultado principal fue la curación primaria del tracto fistuloso y los resultados secundarios incluyeron el éxito en general, las complicaciones y tiempo hasta recurrencia.Se registraron 119 casos (75 ligaduras del tracto de la fístula interesfintérica y 44 BioLIFT). Un cirujano realizó el 84% de los casos de BioLIFT. La tasa de curación primaria fue del 75.0% vs 58.7%, p = 0.08, y la tasa de complicaciones fue del 22.7% vs 17.3%, p = 0.48 comparando BioLIFT vs ligadura del tracto de la fístula interesfintérica. Después de la regresión logística multivariada, el BioLIFT tuvo una tasa de curación significativamente mejor (OR 2.38 [IC 95% 1.01-5.62], p = 0.048). La mediana de seguimiento fue de 9 vs 29 semanas (BioLIFT vs ligadura del tracto de la fístula interesfintérica). El análisis de Kaplan-Meier no demostró diferencias en el tiempo hasta la recurrencia (p = 0,48).Este estudio estuvo limitado por ser retrospectivo, las diferentes duraciones de seguimiento y el número variable de casos entre los cirujanos.La modificación BioLIFT es segura y efectiva para el tratamiento de las fístulas anales pero tiene un costo más alto. Esta modificación amerita más estudios prospectivos para establecer los beneficios sobre ligadura del tracto de la fístula interesfintérica. Consulte Video Resumen en hhttp://links.lww.com/DCR/B139.

[PMID: 32014596 DOI: 10.1016/j.ijsu.2020.01.137] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 01/20/2020] [Accepted: 01/23/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Video-assisted anal fistula treatment (VAAFT) is a new minimally invasive technique for treating complex anal fistula (CAF). This study aimed to compare the efficacy and safety of VAAFT with fistulotomy plus seton (FPS) for treatment of CAF. MATERIALS AND METHODS We included 148 patients with CAF receiving surgical treatment at our hospital between January 2017 and December 2018. Propensity score matching (PSM) analysis was conducted with patients' baseline characteristics, and surgical outcomes were compared between the matched groups. Logistic analysis was performed to identify the risk factors for fistula recurrence after VAAFT. RESULTS Among the study population, 68 and 80 patients underwent VAAFT and FPS, respectively. After PSM, 64 matched pairs of patients were created with no significant differences in baseline characteristics. Compared with FPS, VAAFT had greater efficiency of locating internal openings (90.6% vs. 100%), less intraoperative blood loss (26 ± 15 vs. 12 ± 5 mL), lower incidence of postoperative bleeding (10.9% vs. 1.5%), shorter postoperative hospital stay (6.8 ± 5.1 vs. 5.0 ± 3.3 days), reduced postoperative pain, and decreased wound secretion (all P < 0.05). VAAFT showed a significantly lower Wexner incontinence score than FPS (0.9 ± 1.7 vs. 1.9 ± 2.6, P = 0.003) at 3 months postoperatively, but no significant difference in the healing rate was observed either at 3-month or 1-year (P = 1.000) follow-up. A total of 12 patients (17.6%) developed fistula recurrence after VAAFT, and logistic analysis revealed that multiple fistula tracts, prolonged operating time and severe postoperative wound secretion were independent risk factors (odds risk = 2.18, 3.25 and 3.04, respectively, all adjusted P < 0.05). CONCLUSION Compared with FPS, VAAFT offers some advantages for treatment of CAF, including minimal damage, less pain, rapid recovery, fewer complications and better sphincter preservation.

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 AND OBJECTIVES To validate and analyze the results of intralesional photodynamic therapy in the treatment of complex anal fistula. STUDY DESIGN/MATERIALS AND METHODS This prospective multicentric observational study enrolled patients treated for complex anal fistula who underwent intralesional photodynamic therapy (i-PDT). The included patients were treated from January 2016 to December 2018 with a minimum follow-up of 1 year to evaluate recurrence, continence and postoperative morbidity. Intralesional 5-aminolevulinic acid (ALA) gel (2%) was injected directly into the fistula. The internal and external orifices were closed. After an incubation period of 2 hours, the fistula was irradiated using an optical fiber connected to a red laser (Multidiode 630 PDT) operating at 1 W/cm for 3 minutes (180 J). RESULTS In total, 49 patients were included (61.2% male). The mean age was 48 years, and the mean duration of fistula was 13 months. Of the fistulas included, 75.5% were medium transphincteric, and 24.5% were high transphincteric. The median fistula length was 4 ± 1,14 cm (range: 3-5). A total of 41 patients (83.7%) had a previous history of fistula surgery. Preoperatively, some degree of anal incontinence was found in 5 patients (10.2%). No center reported any other procedure-related complications intraoperatively. Phototoxicity was found in one patient. In the first 48 hours after the procedure, fever was reported in 2 patients (4%). At the end of follow-up, total healing was observed in 32/49 patients (65.3%). No patient reported new incontinence postoperatively. CONCLUSION i-PDT could be considered a good choice in patients with complex anal fistulas to avoid surgery and its complications. Lasers Surg.

Abstract
AIM To compare the rate of failure of radiofrequency thermocoagulation for anal fistula with that of rectal advancement flap in a case-matched study. METHOD Patients who underwent radiofrequency treatment were compared with age- and sex-matched patients with Crohn's disease (CD) who underwent a rectal flap procedure. Fistula features, general characteristics and the main clinical events were recorded in a prospective database. Failure was defined by at least one of following: abscess, purulent discharge, visible external opening or further drainage procedure. RESULTS A total of 62 patients [median age 45 (range 36.8-57.5) years; 22 women, 40 men; 22 with CD] were analysed. The failure rate of radiofrequency treatment was higher than that of rectal flap treatment (74.2% vs 32.2%; P = 0.004). The cumulative probabilities of failure of the radiofrequency treatment were 53.8% (38.8-68.3), 71.8% (55.3-84.0) and 87.4% (70.6-95.3) at 3, 6 and 12 months, respectively. Three patients in the radiofrequency group required drainage for an abscess and one had severe thermal ulceration. The Cox proportional hazards regression model (surgical procedure, obesity, CD) showed rectal flap treatment [3.48 (1.60-8.07); P = 0.001] and CD [2.60 (1.16-6.41); P = 0.02] to be the main independent predictors of healing. CONCLUSION Radiofrequency thermocoagulation is a less satisfactory sphincter-sparing treatment for the management of anal fistula than a rectal flap procedure.

Abstract
BACKGROUND Laser closure is a novel sphincter-saving technique for the treatment of anal fistula. The aim of this study was to report middle term results of laser treatment without closure of the internal orifice and to identify prognostic factors to improve selection criteria and maximize healing. METHODS A retrospective observational study was conducted on patients treated with laser for transphinteric anal fistula. A diode laser emitting laser energy of 12W at a wavelength of 1470 nm was used. The relationship between fistula healing and age, sex, previous fistula surgery, location of fistula, and length of fistula tract was investigated. A successful outcome was defined by the complete healing of the surgical wound and external opening for at least 6 months. RESULTS Thirty patients (16 males, median age 52 years, range 26-72 years) underwent laser fistula closure between January 2015 and December 2016. Cure was achieved in 10 patients (33.3%). The mean follow-up was 11.30 months (range 6-24 months). Patients with persistent or recurrent fistula were offered repeat surgery. Eventually 4 underwent laser treatment once more. Two patients were cured leading to an overall healing rate of 40% (12 out of 30). Only 4 minor complications occurred (13.3%). No worsening of anal continence was registered. Only fistula length had a statistically significant correlation with successful treatment. Fistula tracts shorter than 30 mm were associated with a primary healing rate of 58.3% while tracts longer than 30 mm were cured in only 16.6% of cases (p < 0.02). CONCLUSIONS Laser closure is a safe and effective treatment for transphinteric anal fistula. The fistula length is the only significant prognostic factor when closing anal fistulas exclusively with laser: shorter fistulas have a better outcome.

Abstract
OTSC Proctology is a minimally invasive sphincter-preserving technique for the surgical treatment of anorectal fistulas. It is based on a super-elastic Nitinol clip which closes the internal fistula opening to allow healing of the fistula tract. A systematic search of the literature was undertaken to identify publications about OTSC Proctology. All studies and reports identified were reviewed and evaluated to determine the feasibility, efficacy and safety of clip surgery. The assessment of all available studies with a total of more than 200 surgical cases strongly suggests that the clip procedure is safe and effective with a low rate of complications. The technique rendered convincing short and long term results with an overall healing rate of approximately 63%. Best results were achieved when OTSC Proctology was used as first-line treatment (healing rate 74%) and for cryptoglandular fistulas (healing rate 64%). However, its future clinical role for IBD-associated recurrent and anorecto-vaginal fistulas remains to be determined, due to a relatively low number of these patients in the evaluated studies. OTSC Proctology is part of the novel armamentarium for the treatment for anorectal fistulas, which is based on high-technology devices. They can be repeatedly used and even combined without causing irreversible sphincter damage.

Abstract
BACKGROUND Perianal fistula is a topic both hard to understand and to teach. The key to understanding the treatment options and the likely success is deciphering the exact morphology of the tract(s) and the amount of sphincter involved. Our aim was to explore alternative platforms better to understand complex perianal fistulas through three-dimensional (3D) imaging and reconstruction. METHODS Digital imaging and communications in medicine images of spectral attenuated inversion recovery magnetic resonance imaging (MRI) sequences were imported onto validated open-source segmentation software. A specialist consultant gastrointestinal radiologist performed segmentation of the fistula, internal and external sphincter. Segmented files were exported as stereolithography files. Cura (Ultimaker Cura 3.0.4) was used to prepare the files for printing on an Ultimaker 3 Extended 3D printer. Animations were created in collaboration with Touch Surgery™. RESULTS Three examples of 3D printed models demonstrating complex perianal fistula were created. The anatomical components are displayed in different colours: red: fistula tract; green: external anal sphincter and levator plate; blue: internal anal sphincter and rectum. One of the models was created to be split in half, to display the internal opening and allow complexity in the intersphincteric space to better evaluated. An animation of MRI fistulography of a trans-sphincteric fistula tract with a cephalad extension in the intersphincteric space was also created. CONCLUSION MRI is the reference standard for assessment of perianal fistula, defining anatomy and guiding surgery. However, communication of findings between radiologist and surgeon remains challenging. Feasibility of 3D reconstructions of complex perianal fistula is realized, with the potential to improve surgical planning, communication with patients, and augment training.

Abstract
Crohn's disease is increasingly thought to encompass multiple possible phenotypes. Perianal manifestations account for one such phenotype and represent an independent disease modifier. In its more severe form, perianal Crohn's disease confers a higher risk of a severe and disabling disease course, relapses, hospital admissions and operations. This, in turn, imposes a considerable burden and disability on patients. Identification of the precise manifestation is important, as management is nuanced, with both medical and surgical components, and is best undertaken in a multidisciplinary setting for both diagnosis and ongoing treatment. The introduction of biologic medication has heralded a significant addition to the management of fistulizing perianal Crohn's disease in particular, albeit with modest results. It remains a very challenging condition to treat and further work is required to optimize management in this group of patients.
