Abstract
Different types of lasers have been applied for various proctological conditions. We discuss about published articles regarding the application of lasers, with concern about evidence-based use of these techniques and technologies. We performed a literature search about laser treatments for proctological conditions. 55 studies were included for the final revision. Meta-analysis of data was not performed because of heterogeneity of study designs and outcome measures. A scoping review was performed. Laser treatments for hemorrhoids require a shorter operative time and show less postoperative pain and bleeding compared to conventional hemorrhoidectomy, but are more expensive. Studies are heterogeneous in design, endpoints, postoperative assessment, length of follow-up and outcome measures. Only 3 RCTs are available and only three studies evaluate long-term outcomes. FiLaC (fistula laser closure) was initially described in 2011 for the treatment of anal fistula. In the published studies the reported healing rates vary between 20 and 82%, and the ideal indication is yet to be defined. Studies with long-term follow-up are lacking. SiLaT (sinus laser treatment) applied the technology used for FiLaC to the treatment of pilonidal sinus disease. This technique had less perioperative pain and shorter hospital stay, but a lower primary healing rate when compared to traditional techniques. Available data is very limited, and no randomized trials are published to date. Laser assisted techniques are a viable, minimally invasive, but expensive option for the treatment of several proctological conditions. Further researches are needed to assess if patients could benefit of their use, and for what indication.

Abstract
Background Fistula-in-ano treatment has remained quite challenging with high failure rates and a potential for damage to the anal sphincteric complex leading to flatal or faecal incontinence. The treatment of fistula-in-ano using the fistula laser closure (FiLaC) as a minimally invasive, sphincter-saving procedure for complex disease has recently been documented. Objectives This review aimed to report the outcome of using it at the Lagos University Teaching Hospital. Patients and Methods The procedures were performed with a radially emitting laser fibre from Biolitec AG-CeramOptec (Bonn, Germany). The duration of symptoms, type of fistula, duration of the procedures, and postoperative complications were evaluated. Results Eleven male patients had laser fistula-in-ano closure. The age range was 33-51 years, with a median age of 39 years and an interquartile range (IQR) of 37-47 years. Five patients were noted to have high fistula/e, whereas six had low fistula/e, seven had a single tract each, and three had three tracts each. The duration of surgery ranged, approximately from 3 to 60 min, with a median of 19 min and IQR of 9-33 min. Postoperative pain was mild in all patients and were all discharged as day case. There was no postoperative wound infection, anal incontinence, anal stenosis, and subcutaneous abscess. However, there was a recurrence in two patients. Conclusions FiLaC has been demonstrated to be a reliable and safe sphincter-saving procedure for treating fistula-in-ano even for complex and high fistulae that is feasible in our subregion.

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.

Treatment of cryptoglandular fistulas with the fistula tract laser closure (FiLaC™) method in comparison with standard methods: first results of a multicenter retrospective comparative study in the Netherlands. Tech Coloproctol 2022; 26:797-803. [PMID: 35749023 DOI: 10.1007/s10151-022-02644-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 05/20/2022] [Indexed: 01/23/2023]
Abstract
BACKGROUND Current surgical closure techniques for sphincter-sparing treatment of high cryptoglandular fistulas in the Netherlands include the mucosal advancement flap procedure (MAF) and ligation of the intersphincteric fistula tract (LIFT). A relatively novel treatment is the fistula tract laser closure (FiLaC™) method. The aim of this study was to investigate the differences in healing and recurrence rates between FiLaC™ and current standard practices. METHODS This multicenter retrospective cohort study included both primary and recurrent high cryptoglandular anorectal fistulas, treated with either FiLaC™ or standard methods (MAF or LIFT) between September 2015 and July 2020. Patients with extrasphincteric fistulas, Crohn's disease, multiple fistulas, age < 18 years or missing data regarding healing time or recurrence were excluded. The primary outcomes were the clinical primary and secondary healing and recurrence rates. Primary healing was defined as a closed external opening without fluid discharge within 6 months of treatment on examination, while secondary healing was the same endpoint after secondary treatment. Secondary outcomes included healing time and complaints. RESULTS A total of 162 high fistulas from 3 Dutch hospitals were included. Ninety-nine high fistulas were treated with FiLaC™ and 63 with either MAF or LIFT. There were no significant differences between FiLaC™ and MAF/LIFT in terms of clinical healing (55.6% versus 58.7%, p = .601), secondary healing (70.0% versus 69.2%, p = .950) or recurrence rates (49.5% versus 54%, p = .420), respectively. Median follow-up duration was 7.1 months in the FiLaC™ group (interquartile range [IQR] 4.1-14.4 months) versus 6 months in the control group (IQR 3.5-8.1 months). CONCLUSIONS FiLaC™ treatment of high anorectal fistulas does not appear to be inferior to MAF or LIFT. Based on these preliminary results, FiLaC™ can be considered as a worthwhile treatment option for high cryptoglandular fistulas. Prospective studies with a longer follow-up period and well-determined postoperative parameters such as complication rates, magnetic resonance imaging for confirmation of fistula healing, incontinence and quality of life are warranted.

Abstract
Surgery for benign anal conditions is a common practice and is usually followed by a good outcome. The present review aimed to summarize the emergence and evolution of different laser techniques used for the treatment of benign anal conditions and report their current outcome. PubMed and Scopus were searched for studies that assessed the use of laser in benign anal conditions. Anal conditions reviewed were hemorrhoids, anal fistula, anal warts, anal stenosis, and anal fissure. The full text of the studies retrieved was summarized in a narrative and tabular form. Laser techniques used for the treatment of hemorrhoidal disease were laser open hemorrhoidectomy, laser hemorrhoidoplasty, and Doppler-guided hemorrhoidal laser dearterialization. Resolution of hemorrhoidal symptoms was reported in 72-100% of patients after laser treatment. YAG laser, fistula laser closure, and photodynamic therapy have been used for the treatment of anal fistula with success rates ranging from 20 to 92.6%. Anal warts can be treated with photodynamic therapy with or without YAG or CO2 laser with a success rate up to 88%. A few studies reported the use of laser in the treatment of chronic anal fissure and anal stenosis. The use of laser in the treatment of benign anal conditions is associated with promising outcomes. Laser was most assessed in hemorrhoidal disease and anal fistula and showed more consistent success rates with hemorrhoidal disease than with anal fistula. Preliminary reports assessed the outcome of laser treatment in other conditions as anal fissure and warts with acceptable outcomes.

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.

Abstract
PURPOSE Treatment of ano-cutaneous fistulas remains a therapeutic challenge. Fistula Laser Closure (FiLaC™) is a relatively new technique for the treatment of ano-cutaneous fistulas. This study aimed to determine the success rate of fistula closure using FiLaC™. Secondary endpoints included adverse events and patient characteristics associated with treatment success. METHODS This was a retrospective cohort study of consecutive patients subjected to FiLaC™ at Digestive Disease Center, Bispebjerg University Hospital, Copenhagen, between March 2017 and July 2019. All patients had a one-track fistula not suitable for fistulotomy. All were treated with a draining seton for at least 8 weeks prior to laser closure. Fistulas were ablated with a 360-degree emitting 12-watt 1470 nm laser probe. The inner fistula opening was closed with absorbable suture. All patients were followed with clinical examination including MRI or EAUS 1 year after the procedure. RESULTS In total, 66 patients with 68 fistulas were included. Two patients had a high intersphincteric, 20 had low transsphincteric, 41 high transsphincteric and 5 had suprasphincteric fistulas. Fistula aetiology was cryptoglandular in 83.8%, whereas the rest were due to Crohn's disease. Thirty-one (45.6%) were subjected to a second FiLaC™ procedure. Follow-up was median 19 months (12-26 months). Ultimately, 30 of 68 (44.1%) of the fistulas healed. No cases of incontinence following FiLaC™ were observed, but a single patient developed an abscess. CONCLUSION Fistula closure with FiLaC™ had success rates comparable to that of other sphincter-sparing techniques. The technique seems safe with respect to adverse events and risk of incontinence.

Abstract
BACKGROUND Treatment of fistula-in-ano with fistula laser closure (FiLaC®) is a sphincter-saving procedure indicated for patients with complex anal fistulas. The aim of our study was to evaluate the clinical results of a 10-year experience with FiLaC®. METHODS Data from patients with cryptoglandular anal fistula who underwent laser closure with FiLaC® in June 2009-May 2019 were evaluated. The primary study endpoint was healing rate. Secondary endpoints were evaluation of morbidity and assessment of possible predictive factors of failure. RESULTS Out of a total of 180 patients, 5 had been lost to follow-up. 175 patients [m:f: 115:60; median age 49 years (range18-81 years)] with cryptoglandular fistulas treated with FiLaC® were included in the study. Fistulas were transphincteric in 152 (86.8%) cases, intersphincteric in 18 (10.3%), and suprasphincteric in 5 (2.9%). A seton or draining silicon loop was placed in 142 (81.8%) patients at a median of 14 weeks (range10-28 weeks) prior to FiLaC®. At median follow-up of 60 months (range 9-120 months), the overall primary healing rate was 66.8% (117/175). Thirty-eight patients (21.7%) failed to heal. Twenty out of 175 (11.4%) patients had recurrence at median follow-up of 18 months (range 9-50 months). Patients in whom a seton/loop was inserted for drainage at the first-stage procedure had a statistically significant higher rate of success (100/142, 70.4% vs. 17/33, 51.5%, respectively; p 0.0377; odds ratio 0.45). Forty-eight patients were reoperated on at a median of 15 months (range 12-20 months) after laser treatment. Twenty-six underwent redo laser closure with FiLaC®, and 12 of them healed (46%), for a secondary success rate of 73.7%. CONCLUSIONS Longer follow-up confirms the efficacy of FiLaC® in the treatment of complex anal fistulas. Its use and implementation should be encouraged.

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
One of the most challenging phenotypes of Crohn’s disease is perianal fistulizing disease (PFCD). It occurs in up to 50% of the patients who also have symptoms in other parts of the gastrointestinal tract, and in 5% of the cases it occurs as the first manifestation. It is associated with severe symptoms, such as pain, fecal incontinence, and a significant reduction in quality of life. The presence of perianal disease in conjunction with Crohn’s disease portends a significantly worse disease course. These patients require close monitoring to identify those at risk of worsening disease, suboptimal biological drug levels, and signs of developing neoplasm. The last 2 decades have seen significant advancements in the management of PFCD. More recently, newer biologics, cell-based therapies, and novel surgical techniques have been introduced in the hope of improved outcomes. However, in refractory cases, many patients face the decision of having a stoma made and/or a proctectomy performed. In this review, we describe modern surgical management and the most recent advances in the management of complex PFCD, which will likely impact clinical practice.

The complexity of cryptoglandular fistula-in-ano can be predicted by the distance of the external opening to the anal verge; implications for preoperative imaging? Tech Coloproctol 2020; 25:109-115. [PMID: 33180233 DOI: 10.1007/s10151-020-02353-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Accepted: 09/25/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Many surgeons believe that the distance from the external opening to the anal verge (DEOAV) predicts the complexity of a cryptoglandular fistulas-in-ano and, therefore, predicts the need for additional imaging. However, there is no evidence to support this. The primary aim of this study was to determine if DEOAV can predict the complexity of a fistula. Secondary aims were clinical outcome and identification of those patients that might not benefit from preoperative imaging. METHODS All patients having surgery for cryptoglandular fistula-in-ano between January 2014 and December 2016 were evaluated. Preoperative imaging was used to classify fistulas as simple or complex. The DEAOV was measured preoperatively and was divided into categories ≤ 1 cm, 1-2 cm, or > 2 cm. The relationship between the DEOAV and complexity of the fistula was investigated. Clinical outcome was recorded and a group of patients that might not benefit from preoperative imaging was identified. RESULTS A total of 103 patients [m:f = 65:38, median age 47 (range 19-79) years] were included. Magnetic resonance imaging identified 39 simple and 64 complex fistulas. The percentage of simple fistula was 88% in fistulas with DEAOV ≤ 1 cm, 48% in DEAOV 1-2 cm and 38% in > 2 cm. There was a significant difference between the complexity of the fistula and the distance to the anal verge (p < 0.001). The overall healing rate was 88%. CONCLUSIONS The complexity of perianal fistula depends on the DEAOV. We propose that preoperative imaging should be performed in fistulas with external opening > 1 cm from the anal verge.

Abstract
BACKGROUND The treatment of anal fistula remains a challenge between maintaining continence and radical surgery to prevent recurrence. Fistula-tract Laser Closure (FiLaC®) is a sphincter-saving technique using a radial emitting laser fibre to close the fistula tract. The aim of this study was to report long-term outcomes in patients who received FiLaC® therapy for transsphincteric and intersphincteric anal fistula between January 2011 and December 2017. METHODS A retrospective study was performed on patients who were treated with FiLaC®- for a transsphincteric and intersphincteric anal fistula at our institution between January 2011 and December 2017. In all patients, the FiLaC® procedure was combined with a closure of the internal orifice using a simple 3-0 Z stitch. Patient characteristics, previous proctological history, healing rates, failures and postoperative continence were investigated. RESULTS The study included 83 patients [mean age 50.01 ± 14.59 years. 64 (77.1%) males] with a mean follow-up period of 41.99 (± 21.59) months (range 4-87 months). Thirteen patients (15.7%) had a recurrent fistula. 65 patients (78.3%) had undergone prior abscess drainage with insertion of a seton. The primary healing rate was 74.7% (62 of 83 patients) overall. Eleven (13.3%) of the 21 patients (25.3%) who failed FiLaC®-therapy underwent a second operation. In eight cases, Re-FiLaC® and in three cases, fistulectomy with closure of the internal orifice was performed. Afterwards 6 (54.5%) of these 11 patients could be considered cured: 3 who had fistulectomy and three who had Re-FiLaC® treatment. The overall healing rate after second FiLaC® was 78.3% (65 of 83 patients) while the overall healing rate for FiLaC® therapy combined with any second procedure was 81.9% (68 of 83 patients). The follow-up period in this group of 11 patients who received re-operation was 38 months (range 13-84 months). Changes in continence occurred in eight patients (9.6%). No patient reported major incontinence postoperatively. CONCLUSIONS The FiLaC® procedure is associated with good healing rates in long-term follow-up and should be considered as a treatment option for transsphincteric and intersphincteric anal fistulae, especially due to the low complication rate and low risk of sphincter injury.
