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.

Abstract
Background Anal fistulas are a common complication of perianal abscesses. The treatment of anal fistulas is challenging, with persistent and high recurrence rates. The aim of this study was to evaluate the efficacy and cost-effectiveness of laser ablation compared to fistulotomy in the treatment of anal fistulas. Materials and methods The patients were examined for external and internal openings of the fistula, its number, length, type, relationship with the sphincters, and any previous history of abscess or proctological surgery. The surgical procedures, complications, incontinence, recurrence, and recovery time were evaluated and compared between the two groups. The laser ablation group received an intermittent laser application at a wavelength of 1470 nm and 10 watts for three seconds, while the fistulotomy group underwent cutting of the fistula tract with electrocautery while keeping a stylet in place. Results A total of 253 patients were included in this retrospective study, with 149 patients undergoing fistulotomy and 104 patients undergoing laser ablation. The patients were evaluated based on the type, number, and location of internal and external openings, and the length of the fistula tract according to the Parks classification. The mean follow-up period was 9.0±4.3 months. The results showed that the laser group had a shorter time to return to work and less postoperative pain compared to the fistulotomy group. However, the recurrence rate was higher in the laser group. The recurrence rate was also found to be higher in patients with low transsphincteric fistulas and in patients with diabetes mellitus. Conclusion Our study findings indicate that while laser ablation may be associated with less pain and quicker recovery time, it may also have a higher recurrence rate compared to fistulotomy. We believe that laser ablation is a valuable option for surgeons to consider early on in the treatment process, especially in cases where fistulotomy is not suitable.

Abstract
Background Video-assisted anal fistula treatment (VAAFT) may have a recurrence rate comparable to that of fistulectomy and sphincter repair (FSR) in the treatment of high anal fistula and with potential advantages in wound healing, functional outcome and quality of life. The aim and objectives of the study are to compare the outcome of VAAFT with that of FSR for high cryptoglandular anal fistula. Methods This was a single-centre randomized controlled trial of adults with high anal fistula comparing FSR with VAAFT. Primary outcome was fistula recurrence. Secondary outcomes were results of anal manometry, quality of life and faecal continence. A power calculation of 33 patients in each arm (1 : 1) was based on recurrence in the FSR and VAAFT groups of 5 per cent and 30 per cent respectively. Follow-up at 6 months after surgery included physical examination, MRI, anal manometry, quality-of-life assessment (RAND SF 36 questionnaire) and faecal-continence assessment (Wexner score). Results The study was terminated early due to high recurrence rates in both groups. A total of 45 patients were included. Recurrence rates were 65 per cent for VAAFT and 27 per cent for FSR, with hazard ratio 4.18 (P = 0.016). Length of the fistula was a risk factor with an association with recurrence (hazard ratio 1.8, P = 0.020). There were significant differences in quality of life in favour of FSR and in anal manometry in favour of VAAFT with a significant improvement in Wexner score in both groups. Conclusion FSR was associated with a lower recurrence rate than VAAFT in the management of complex anal fistulae in this single-centre study but the study was terminated early due to higher than predicted recurrence rate in both groups. Registration number NCT02585167 (http://www.clinicaltrials.org).

VAAFT for complex anal fistula: a useful tool, however, cure is unlikely. Tech Coloproctol 2021; 25:1115-1121. [PMID: 34318362 DOI: 10.1007/s10151-021-02492-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 06/19/2021] [Indexed: 02/07/2023]
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
Background: Treating anal fistulae is still a great challenge due to the possibility of fecal incontinence after surgery and that the use of laser has been gaining space in medicine, including as an inducing method of healing.
Aim:
To evaluate the efficacy of low-level laser therapy on fistula-in-ano treatment in rats.
Methods: Fifteen male Wistar rats weighing approximately 250-300g were used, which were subjected to the anal fistula induction procedure and after 30 days were distributed into two groups: control group (CG, n=5) and laser group (LG, n=10) observed for another 30 days. In the CG no treatment was performed and, in the LG, low-level laser therapy was applied in fistulous tracts daily. The closure of the fistulous tract, the area of the remaining tract, the inflammatory infiltrate and vascular congestion were evaluated.
Results:
There was no complete closure of the tract in any of the animals. The mean area of the remaining tract was 847.2 µm2 in the CG and 248.5 µm2 in the LG (p=0.001). The mean inflammatory infiltrate score was 2.4 in the CG and 1.3 in the LG (p=0.0285), while in the evaluation of vascular congestion, 1.6 was observed in the CG and 0.6 in the LG (p=0.031).
Conclusions: Low-level laser therapy was able to reduce the area of the fistulous tracts as well as decrease the inflammatory process and local vascular congestion.

Abstract
Abstract
Introduction The pilonidal cyst is a chronic inflammatory process that occurs frequently in the sacrococcygeal region. It is more common in males with a ratio of 3:1 and usually presents itself in the third decade of life. The treatment is mainly surgical with various forms. The search for new technologies as well as for a minimally invasive treatment has become of utmost importance in surgical routines. The technique E.P.Si.T. (endoscopic treatment of pilonidal cyst) developed by Meneiro has been quite interesting in the treatment of pilonidal cysts.
Surgical technique Anesthetized the patient in the supine position. Identified the drainage hole of the cyst, and began with the passage of fistuloscope studying the path of the cyst. Performs following the removal of all the tissue inside as the hair followed by cauterization of the path. Removed all devitalized tissue and enlargement of the opening of the cyst.

Abstract
Objectives: The anal fistula is a permanent infectious tunnel formed between the anal canal and skin in the perianal region. Fistulas are treated by surgery at any stage. Many surgical methods have been reported to treat anal fistula. One of the promising surgical methods with a high success rate is ligation of the intersphincteric fistula tract, which is performed in anatomical spaces without damage to the internal and external sphincters. We evaluated the success rate of a modified ligation of the intersphincteric fistula tract procedure for complex anal fistulas in which the technical differences were minimized by the surgery being performed by the same surgical team. Methods: In this study, Data of the 56 patients were retrospectively collected. Data regarding patient history, visual and digital anal examination, Cleveland Clinic Florida Fecal Incontinence (CCF-FI) score, anal-phase pelvic magnetic resonance imaging (MRI), rectosigmoidoscopy or colonoscopy and anal manometry were recorded. The changes in data recorded during the preoperative and postoperative periods were compared in each other. Results: The mean age of the patients was 41±15.5 years. The number of patients for each fistula type compromised in this study was as follows in accordance with frequency: high transsphincteric fistula, high intersphincteric fistula, and horseshoe abscess. The fistula recurred in seven patients during postoperative follow-up and the success rate of modified LIFT was calculated as 87.5%. The change in the mean±SD preoperative and postoperative CCF-FI scores and anal pressure was not statistically significant. Conclusion: One promising advantage of the ligation of the intersphincteric fistula tract procedure is that it turns a complex fistula into a simple fistula that can be treated with minimal risk of sphincter damage.

Abstract
Aim: The aim of this prospective, nonrandomized, observational study was to present our results in operative treatment of complex anal fistulas using video-assisted anal fistula treatment (VAAFT) procedure with a curative intent in 2 years follow-up period. Materials and Methods: Between March 2016 and March 2018, 73 patients underwent the VAAFT procedure. Postoperative follow-up was 2 years, up to March 2020. Only patients with complex cryptoglandular anal fistulas were included. All patients were referred for magnetic resonance imaging of the pelvis. Fecal incontinence severity index score was used to assess any continence disturbance prior operation and postoperatively. Result: Primary healing occurred in 52 cases (71.23%) after first operation. From 21 patients who had recurrence or who had persisting disease, 16 patients accepted reoperation with second VAAFT procedure and additionally 10 patients achieved healing. From a total number of 73 patients who were included in study healing ultimately occurred in 62 cases (84.93%). In the first operation internal opening was identified in 47 cases (64.38%) and was closed with mattress suture, rectal advancement flap or ligation of intersphincteric fistula tract technique depending on its extent and type of fistula. Median primary healing rate was 6 weeks. There were no serious intra- or postoperative complications. None of the patients reported any type of continence disturbance. Discussion: VAAFT has been shown to offer good rates of healing, low morbidities, possibilities of multiple attempts in case of first failure and this series adds to the literature.

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 Anal fistula is by definition the communication between the rectum or anal canal with the perineal region, which may be epithelialized and has cryptoglandular origin in 90% of cases. There are a large number of techniques for successfully treating trans-sphincteric fistulas of 20-50%, including primary sphincteroplasty, but it is not clear whether the material used would influence the outcome. AIM To analyze the efficacy of polydioxanone and polypropylene wire in primary post-fistulotomy sphincteroplasty in the treatment of trans-sphincteric fistulas in rats. METHODS Thirty Wistar rats had transfixation of the anal sphincter with steel wire, which remained for 30 days for the development of the anal fistula. After this period, it was removed and four groups were formed: A (control) without treatment; B (fistulotomy) submitted to such procedure and curettage only; C (polidioxanone) in which sphincteroplasty was performed after fistulotomy with polydioxanone wire; D (polypropylene) submitted to the same treatment as group C, but with polypropylene wire. After 30 days, euthanasia and removal of the specimens were performed for qualitative histopathological analysis, measurement of the area between the muscular cables edges and evaluation of the degree of local fibrosis. RESULTS There was persistence of the anal fistula in all animals of group A. There were no significant differences between groups B, C and D regarding the distance of the muscular cables (p=0.078) and the degree of fibrosis caused by the different treatments (p=0.373). CONCLUSIONS There was no difference between polydioxanone and polypropylene wires in post-fistulotomy primary sphincteroplasty, and this technique was not superior to simple fistulotomy in relation to the distance of the muscular cables nor did it present differences in relation to the degree of local fibrosis.

Abstract
Background: The best treatment for anal fistula should extirpate infection and promote healing of the tract, whilst preserving the anal sphincter complex and full continence. Aim: To analyze the success rate after a modified technique for ligation of the intersphincteric fistula tract (LIFT) for patients with anal fistulas. Methods: A prospective (observational cohort study) Brazilian bi-institutional experience with a modified (ligation of the intersphincteric fistula tract without excision) LIFT technique was undertaken. A clinical database was settled for the following variables: age, gender, BMI, comorbidities, distance between external orifice and the anus, previous fistula surgery, type of fistula, operative time, intra- and postoperative complications, duration of follow-up, and success rate. Results: Between November 2015 and January 2017, 38 patients with transsphincteric fistulas were operated on using the modified LIFT procedure. Seventeen (44.7%) were men. Median age was 41 (18-67) years. Median BMI was 26.4 (22-38) kg/m2. Five (13.2%) had undergone previous surgery. The fistula was transsphincteric in all cases. Median follow-up was 32 (range, 14-56) weeks. Success was observed in 30 (79%) patients. Conclusions: The LIFT technique without excision of the fistula tract proved to be safe and effective for transsphincteric anal fistulas.

Abstract
BACKGROUND The surgical treatment of complex anal fistulae, particularly those involving a significant portion of the anal sphincter in which fistulotomy would compromise continence, is challenging. Video-assisted anal fistula treatment (VAAFT), fistula tract laser closure (FiLaC™) and over-the-scope clip (OTSC®) proctology system are all novel sphincter-sparing techniques targeted at healing anal fistulae. In this study, all published articles on these techniques were reviewed to determine efficacy, feasibility and safety. METHODS A systematic search of major databases was performed using defined terms. All studies reporting on experience of these techniques were included and outcomes (fistula healing and safety) evaluated. RESULTS Eighteen studies (VAAFT-12, FiLaC™-3, OTSC®-3) including 1245 patients were analysed. All were case series, and outcomes were heterogeneous with follow-up ranging from 6 to 69 months and short-term (< 1 year) healing rates of 64-100%. Morbidity was low with only minor complications reported. There was one report of minor incontinence following the first reported study of FiLaC™, and this was treated successfully at 6 months with rubber band ligation of hypertrophied prolapsed mucosa. There are inconsistencies in the technique in studies of VAAFT and FiLaC™. CONCLUSIONS All three techniques appear to be safe and feasible options in the management of anal fistulae, and short-term healing rates are acceptable with no sustained effect on continence. There is, however, a paucity of robust data with long-term outcomes. These techniques are thus welcome additions; however, their long-term place in the colorectal surgeon's armamentarium, whether diagnostic or therapeutic, remains uncertain.

[PMID: 29052068 DOI: 10.1007/s00464-017-5905-2] [Citation(s) in RCA: 78] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2017] [Accepted: 09/17/2017] [Indexed: 12/13/2022]
Abstract
BACKGROUND Video-assisted anal fistula treatment (VAAFT) is a novel, minimally invasive technique for the treatment of fistula-in-ano (FIA). This review aimed to search the literature for the outcome of VAAFT regarding the recurrence and complication rates of the technique. METHODS A systematic literature search was conducted in compliance with the PRISMA screening guidelines. PubMed/MEDLINE and Scopus were searched for articles reporting the outcomes of VAAFT procedure from inception through April 2017. The main outcomes were patients' characteristics, technical aspects, operation time, recurrence, and complication rates. RESULTS Eleven studies (n = 788 patients) were included. The mean age of the patients was 39.5 years. 66.5% of patients had high or complex FIA and 18.4% underwent previous fistula surgery. The internal opening of the fistula was detected in 85.7% of patients. The mean operation time was 42 ± 14.2 min. The weighed mean rate of detection of internal opening was 93.3%. Recurrence occurred in 112 (14.2%) patients after a median follow-up of 9 months. Recurrence rates varied according to method of closure of internal opening from 15.3% after using staplers, 17.7% after suturing, to 25% after advancement flap. The weighted mean recurrence rate across the studies was 17.7%. The weighted mean complication rate was 4.8%. CONCLUSION VAAFT may be considered an effective diagnostic tool and a safe method for the treatment of complex and high FIA attaining satisfactory outcome and acceptably low complications. Recurrence after VAAFT may be related to previous fistula surgery and the method of closure of the internal opening.

Abstract
BACKGROUND Video-Assisted Anal Fistula Treatment (VAAFT) is a relatively new minimally invasive videoendoscopic procedure for treating fistula-in-ano. We reviewed and performed metaanalysis to evaluate the efficacy of this procedure. METHODS Studies from the period 2010 to 2016 were searched in PubMed, Medline, Scopus, Embase, Ovid, SCI database, Cochrane Central Register of Controlled Trials (CENTRAL) & Google Scholar database. All studies which utilized VAAFT to treat fistula-in-ano were extracted. The studies in which the Cryptoglandular fistula were treated were included. Procedure's done in patients with Crohn's disease, pediatric patients and associated malignancy were excluded from the study. The primary outcome parameter was success rate in fistula healing and the secondary outcome parameters were operating time, hospital stay, return to work, incontinence rate and complication rate. RESULTS A total of 1378 studies were screened. Out of these, eight studies were finally included for meta-analysis. The analysis (n = 786) demonstrated a net Proportion Meta-analysis pooled rate of 76.01% (95% CI = 68.1 to 83.9) for success rate, 16.2% (95% CI = 12.1 to 20.2) for complications, 44.7 min (95% CI = 38.3 to 51.2) for operating time, 1-4.1 days for mean hospital stay and 1-11 days for return to work. None of the studies reported worsening of continence levels. CONCLUSIONS VAAFT is a safe videoendoscopic method to treat fistula-in-ano with an overall success rate of 76% (net Proportion Meta-analysis pooled rate). The main benefit of the procedure is minimal risk to incontinence, minimal hospital stay and early return to work.

Abstract
BACKGROUND Although many attempts have been made to advance the treatment of complex anal fistula, it continues to be a difficult surgical problem. This study aimed to describe the novel technique of video-assisted anal fistula treatment (VAAFT) and our preliminary experiences using VAAFT with patients with complex anal fistula. MATERIAL AND METHODS From May 2015 to May 2016, 52 patients with complex anal fistula were treated with VAAFT at Yangpu Hospital of Tongji University School of Medicine, and the clinical data of these patients were reviewed. RESULTS VAAFT was performed successfully in all 52 patients. The median operation time was 55 minutes. Internal openings were identified in all cases. 50 cases were closed with sutures, and 2 were closed with staplers. Complications included perianal sepsis in 3 cases and bleeding in another 3 cases. Complete healing without recurrence was achieved in 44 patients (84.6%) after 9 months of follow-up. No fecal incontinence was observed. Furthermore, a significant improvement in Gastrointestinal Quality of Life Index (GIQLI) score was observed from preoperative baseline (mean, 85.5) to 3-month follow-up (mean, 105.4; p<0.001), and this increase was maintained at 9-months follow-up (mean, 109.6; p<0.001). CONCLUSIONS VAAFT is a safe and minimally invasive technique for treating complex anal fistula with preservation of anal sphincter function.

Abstract
Management of complex perineal fistulas such as high perianal, rectovaginal, pouch-vaginal, rectourethral, or pouch-urethral fistulas requires a systematic approach. The first step is to control any sepsis with drainage of abscess and/or seton placement. Patients with large, recurrent, irradiated fistulas benefit from stoma diversion. In patients with Crohn's disease, it is essential to induce remission prior to any repair. There are different approaches to repair complex fistulas, from local repairs to transperineal and transabdominal approaches. Simpler fistulas are amenable to local repair. More complex fistulas, such as those secondary to irradiation, require interposition of healthy, well-vascularized tissue. The most common flap used for this treatment is the gracilis muscle with good outcomes reported. Once healing is confirmed by imaging and endoscopy, the stoma is reversed.

Abstract
Objective: To share our findings that the new treatment modality Video Assisted Anal Fistula Treatment (VAAFT) is a better alternate to the conventional treatments of Fistula in Ano in our setup with minor changes in the initial method described by Meinero. Methods: Karl Storz Video equipment including Meinero Fistuloscope was used. Key steps are visualization of the fistula tract, correct localization of the internal fistula opening under direct vision and endoscopic treatment of the fistula. This is followed by an operative phase of fulguration of the fistula tract using glycine solution mixed with manitol, curetting the tract with curette and fistula brush. Internal opening is closed with a Vicryl 1 suture. Result: Total of 40 patients were operated using VAAFT from October 2013 to March 2014. Three were re-operated. The other 37 cases were followed up at 6 weeks, 3 months and 6 months. Primary healing took place in 20 (50%) cases at 6 weeks. In the remaining 17 (42.5%) cases, minor discharge occurred with itching which resolved till the next visit at 8 weeks and 12 weeks. Conclusion: As the main aim in treating fistula is proper identification of the internal opening, excision of the tract and sparing the sphincter function, VAAFT achieves all aims with additional benefits of patients’ satisfaction and negligible scaring.
