Abstract
OBJECTIVES To explore the utilization of three-dimensional (3D) endoanal ultrasound (EAUS) for the follow-up of the anal fistula plug (AFP), describe morphological findings in postoperative 3D EAUS, and evaluate if postoperative 3D EAUS combined with clinical symptoms can predict AFP failure. MATERIALS AND METHODS A retrospective analysis of 3D EAUS examinations performed during a single-centre study of prospectively included consecutive patients treated with the AFP between May 2006 and October 2009. Postoperative assessment by clinical examination and 3D EAUS was performed at 2 weeks, 3 months and 6-12 months ("late control"). Long-term follow-up was carried out in 2017. The 3D EAUS examinations were blinded and analysed by two observers using a protocol with defined relevant findings for different follow-up time points. RESULTS A total of 95 patients with a total of 151 AFP procedures were included. Long-term follow-up was completed in 90 (95%) patients. Inflammation at 3 months, gas in fistula and visible fistula at 3 months and at late control, were statistically significant 3D EAUS findings for AFP failure. The combination of gas in fistula and clinical finding of fluid discharge through the external fistula opening 3 months postoperatively was statistically significant (p < 0.001) for AFP failure with 91% sensitivity and 79% specificity. The positive predictive value was 91%, while the negative predictive value was 79%. CONCLUSIONS 3D EAUS may be utilized for the follow-up of AFP treatment. Postoperative 3D EAUS at 3 months or later, especially if combined with clinical symptoms, can be used to predict long-term AFP failure.ClinicalTrials.gov identifier NCT03961984.

García-Olmo D, Gómez-Barrera M, de la Portilla F. Surgical management of complex perianal fistula revisited in a systematic review: a critical view of available scientific evidence. BMC Surg 2023; 23:29. [PMID: 36740680 PMCID: PMC9901165 DOI: 10.1186/s12893-023-01912-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 01/10/2023] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Treating complex perianal fistulas in Crohn's disease patients remains a challenge. Classical surgical treatments for Crohn's disease fistulas have been extrapolated from cryptoglandular fistulas treatment, which have different etiology, and this might interfere with its effectiveness, in addition, they increase fecal incontinence risk. Recently, new surgical techniques with support from biological approaches, like stem cells, have been developed to preserve the function of the sphincter. We have performed a systematic literature review to compare the results of these different techniques in the treatment of Crohn's or Cryptoglandular fistula. METHODS PubMed, EMBASE, Database of Abstracts of Reviews of Effectiveness, Cochrane Central Register of Controlled Trials were searched systematically for relevant articles. We included randomized controlled trials and observational studies that referred to humans, were written in English, included adults 18+ years old, and were published during the 10-year period from 2/01/2010 to 2/29/2020. Evidence level was assigned as designated by the Scottish Intercollegiate Guidelines Network. RESULTS Of the 577 citations screened, a total of 79 were ultimately included in our review. In Crohn's disease patients, classical techniques such as primarily seton, Ligation of Intersphincteric Fistula Tracks, or lay open, healing rates were approximately 50-60%, while in cryptoglandular fistula were around, 70-80% for setons or flaps. In Crohn's disease patients, new surgical techniques using derivatives of adipose tissue reported healing rates exceeding 70%, stem cells-treated patients achieved higher combined remission versus controls (56.3% vs 38.6%, p = 0.010), mesenchymal cells reported a healing rate of 80% at week 12. In patients with cryptoglandular fistulas, a healing rate of 70% using derivatives of adipose tissue or platelets was achieved, and a healing rate of 80% was achieved using laser technology. Fecal incontinence was improved after the use of autologous platelet growth factors and Nitinol Clips. CONCLUSION New surgical techniques showed better healing rates in Crohn's disease patients than classical techniques, which have better results in cryptoglandular fistula than in Crohn's disease. Healing rates for complex cryptoglandular fistulas were similar between the classic and new techniques, being the new techniques less invasive; the incontinence rate improved with the current techniques.

Abstract
AIM Fistula-in-ano (FIA) is associated with high treatment costs and has a deleterious impact on quality of life. A wide range of healing, incontinence and recurrence rates have been reported. This study aimed to identify operative, patient and disease factors that influence these outcomes after surgery for FIA. METHOD An observational cohort study of consecutive patients who were managed for FIA at a tertiary colorectal practice (1999-2019) was performed. Outcome measures included healing, impaired continence and the need to reoperate. Clinico-pathological variables, including patient comorbidities, fistula anatomy and operative approach, were assessed for their association with these outcomes. RESULTS Some 411 procedures were performed on 263 patients [median age 41.8 years (range 17.8-79.7 years), 184 men (70.0%)]. Some 77.9% of patients achieved complete healing, 9.5% experienced some deterioration in continence postoperatively and 37.6% required reoperation at a median time of 19.0 weeks. Poorer healing was associated with Crohn's disease, high trans-sphincteric fistulas, extrasphincteric fistulas and steroid usage. Poorer continence was associated with female sex, age > 40 years, posterior location, suprasphincteric fistulas, seton insertion and having more than three subsequent procedures. The need to reoperate was associated with female sex, high trans-sphincteric fistulas, suprasphincteric fistulas, inflammatory bowel disease and previous operations for FIA. CONCLUSION Minimizing recurrence of FIA and preservation of continence can be competing management goals. More than one in three patients require reoperation, one in five fails to heal completely and one in ten suffers worsened continence following surgery. Awareness of the factors that contribute to these outcomes is important to the process of informed consent and managing patient expectations before surgery.

Abstract
Purpose Bioprosthetic plugs are appealing, allow simple, repeatable applications, preserve sphincter integrity, minimize patient discomfort, and allow subsequent surgical options when needed. However, success rates vary widely. This study assessed the healing rate in our department when both the Cook-Surgisis and the Gore fistula plugs were used and the long-term effectiveness of using anal plugs for managing anal fistulae. Methods A chart review was performed for patients who had undergone plug insertion between January 2008 and December 2015 at Copenhagen University Hospital, Hvidovre. Data were collected through a prospectively collected database. Plugs were inserted according to guidance provided by 2 experienced surgeons. Long-term results were determined by clinical visits 3, 6, and 12 months after surgery and once yearly thereafter. Results From 2008 to 2015, 36 fistula plugs were inserted. During the follow-up period with a median duration of 18 months (range, 7-60 months), the fistulae of 52.8% of the patients healed. The plug failure rate was 44.4%, and the fistula recurrence rate was 26.3%. The median time to recurrence was 12 months. The overall success rate for plug treatment in our department was 39% when adjusted for recurrence. Conclusion The use of bioprosthetic plugs to treat patients with complex anal fistulae seems to be a safe, viable option for complex fistula repair when other surgical attempts have failed. However, it should not be the treatment of choice. Further prospective randomized studies with a sufficient sample-size and standardized measurements are necessary to evaluate the efficacy of fistula plugs fully.

Abstract
BACKGROUND Primary closure of the fistula tract using energy emitted by a radial fiber connected to a diode laser is a novel procedure for treating perianal fistulas. OBJECTIVE The aim of this study was to determine the long-term effectiveness of this new technique. DESIGN The surgical objective was to seal the fistula tract using laser energy. SETTINGS The study was conducted at a single day-case surgery center. PATIENTS Between April 2012 and June 2016, 103 consecutive patients with primary or recurrent perianal fistula underwent a laser closure procedure using a 12-watt laser emitting at a wavelength of 1470 nm. MAIN OUTCOME MEASURES Patients were classified according to the Park classification, and healing was evaluated based on the perianal fistula disease severity score. RESULTS Among the 103 patients treated using the laser closure procedure, 82 (80%) were men and 21 (20%) were women. The median age of the patients was 43 years (range, 18-78 y). Fifty-three patients (52%) had previous perianal fistula repair surgery. Based on the Park classification, 56 patients (54%) had intersphincteric fistula, 29 (28%) had transsphincteric fistula, 11 (11%) had suprasphincteric or extrasphincteric fistula, and 7 (7%) had superficial perianal fistula. Based on the perianal disease severity score, 41 patients (40%) obtained overall complete healing, 38 (37%) had persistent symptomatic drainage, 20 (19%) had slight drainage with minimal symptoms, and 4 (4%) had painful symptomatic drainage. LIMITATIONS This was a retrospective analysis of noncomparative data with a lack of formal prospective continence assessment. CONCLUSIONS Closure of perianal fistulas using a laser should be considered as a treatment option but with modest expectations. Although our complete healing rate was not as high as in earlier studies, this technique is a reasonable option with nearly no risk of sphincter damage when treating perianal fistulas.

Final results of a European, multicentre, prospective, observational study of Permacol™ collagen paste injection for the treatment of anal fistula. Colorectal Dis 2018; 20:243-251. [PMID: 28493393 DOI: 10.1111/codi.13715] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Accepted: 12/07/2016] [Indexed: 12/22/2022]
Abstract
AIM Permacol™ collagen paste (Permacol™ paste) is an acellular cross-linked porcine dermal collagen matrix suspension for use in soft-tissue repair. The use of Permacol™ paste in the filling of anorectal fistula tract is a new sphincter-preserving method for fistula repair. The MASERATI100 study was a prospective, observational clinical study with the objective to assess the efficacy of Permacol™ collagen paste for anal fistula repair in 100 patients. METHOD Patients (n = 100) with anal fistula were treated, at 10 European surgical sites, with a sphincter-preserving technique using Permacol™ paste. Fistula healing was assessed at 1, 3, 6 and 12 months post-treatment, with the primary end-point being healing at 6 months. Faecal continence and patient satisfaction were surveyed at each follow-up; adverse events (AEs) were monitored throughout the follow-up. RESULTS At 6 months postsurgery, 56.7% of patients were healed and the percentage healed was largely maintained, with 53.5% healed at 12 months. Regarding AEs, 29.0% of patients had at least one AE, and 16.0% of patients had one or more procedure-related AE. Most AEs reported were minor and similar to those commonly observed after fistula treatment, and the incidence of serious adverse events was low (4.0% of patients). Regardless of treatment outcome, 73.0% of patients were satisfied or very satisfied with the procedure. CONCLUSION Permacol™ paste is a promising sphincter-preserving treatment for anal fistulae and has minimal adverse side-effects.

Abstract
AIM The treatment of transsphincteric anal fistula requires a balance between eradication of the disease and preservation of faecal control. A cutting seton is an old tool that is now out of vogue for many surgeons. We hypothesized that the concept remains reliable and safe with results that exceed those reported for many of the more recently described methods. METHOD A retrospective review was conducted of real-time electronic health records (single institution, single surgeon) of patients presenting during the 14 years between 2001 and 2014 with a transsphincteric anal fistula who were treated with a cutting seton. Excluded were patients with Crohn's disease, fistulae related to malignancy or a previous anastomosis and patients whose fistula was treated by another method including a loose draining seton. Data collection included demographics, duration of the disease, duration of the treatment, outcome and continence. RESULTS In all, 121 patients (80 men) of mean age 40.2 ± 12.2 years (range 18-76) with a mean follow-up of 5.1 ± 3.3 (1-24) months were included in the analysis. The median duration of symptoms was 6 (1-84) months; 36% had failed other fistula surgery, 12% had a complex fistula with more than one track and 35% had some form of comorbidity. The median time to healing was 3 (1-18) months; 7.4% required further surgery, but eventually 98% had complete fistula healing. The incontinence rate decreased postoperatively to 11.6% from 19% before treatment with 17/121 with pre-existing incontinence resolved and 8/107 new cases developing. CONCLUSION Despite its retrospective non-comparative design, the study has demonstrated that a cutting seton is a safe, well tolerated and highly successful treatment for transsphincteric anal fistula and is followed overall by improved continence. The results compare very favourably with other techniques.

Abstract
AIM Permacol collagen paste (Permacol paste) is a new option for the treatment of anorectal fistula. It functions by filling the fistula tract with an acellular crosslinked porcine dermal collagen matrix suspension. The MASERATI 100 study group was set up to evaluate the clinical outcome of Permacol paste in the treatment of anorectal fistula. This paper reports the results from the initial 30 patients enrolled in the MASERATI 100 prospective, observational clinical trial. METHOD Patients (N = 30) with anal fistula presenting to 10 European academic surgical units were treated with a sphincter-preserving technique using Permacol paste. Fistula healing was assessed at 1, 3, 6 and 12 months after treatment, with the primary end-point of fistula healing at 6 months post-surgery. Faecal continence and patient satisfaction were recorded at each follow-up visit and adverse events were monitored throughout the follow-up. RESULTS Of the 28 patients with data at 6 months post-surgery, 15 (54%) were healed, and the healing rate was maintained at 12 months. Healing after treatment with Permacol paste was similar for intersphincteric to transsphincteric fistulae and primary or recurrent fistulae. Only one patient exhibited an adverse event (perianal abscess) that was possibly related to the treatment. At the last outpatient visit, over 60% of patients were satisfied or very satisfied with the operation. CONCLUSION Permacol paste is shown to be effective in treating primary and recurrent cryptoglandular anorectal fistula with minimal unwanted side effects.

Abstract
Introduction In a recent Cochrane review, the authors concluded that there is an urgent need for well-powered, well-conducted randomized controlled trials comparing various modes of treatment of fistula-in-ano. Ten randomized controlled trials were available for analyses: There were no significant differences in recurrence rates or incontinence rates in any of the studied comparisons. The following article reviews the studies available for treatment of fistula-in-ano with a fistula plug with special attention paid to the technique. Material and Methods PubMed, Medline, Embase, and the Cochrane medical database were searched up to July 2015. Sixty-four articles were relevant for this review. Results Healing rates of 50–60% can be expected for treatment of complex anal fistula with a fistula plug, with a plug-extrusion rate of 10–20%. Such results can be achieved not only with plugs made of porcine intestinal submucosa but also those made of other biological or synthetic bioabsorbable mesh materials. Important technical steps are firm suturing of the head of the plug in the primary opening and wide drainage of the secondary opening. Discussion Treatment of a complex fistula-in-ano with a fistula plug is an option with a success rate of 50–60% with low complication rate. Further improvements in technique and better studies are needed.

Abstract
AIM The study evaluated, in a proof of concept, the usefulness of a prosthesis (plug) in addition to video assisted ablation of pilonidal sinus (VAAPS) for treatment of recurrent pilonidal sinus. METHOD This is a case series of recurrent complex pilonidal sinus treated by VAAPS plus plug positioning. RESULTS Four patients were analysed. All were successfully treated by this new approach. No difficulties in inserting the plug were identified. Complete healing was achieved in all cases. No infection or recurrence was reported during a limited follow-up. CONCLUSION This new technique allows a minimally invasive scarless approach to recurrent pilonidal sinus.

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