[PMID: 39170146 PMCID: PMC11336288 DOI: 10.1016/j.heliyon.2024.e35024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 07/21/2024] [Accepted: 07/22/2024] [Indexed: 08/23/2024] Open
Abstract
Background High horseshoe-shaped anal fistula (HHAF) is a complex disease that manifests in the perianal region and typically requires surgical intervention for treatment. However, the current therapeutic approaches are limited by the high rates of postoperative recurrence and anal incontinence. To overcome the limitations of traditional surgical approaches, we introduce the bared external anal sphincter (BEAS) technique. Our study aims to compare the clinical efficacy of BEAS surgery with that of the modified Hanley procedure in a real-world setting. Materials and methods This single-centre, prospective cohort study will be conducted in a tertiary hospital in China and aims to evaluate the short-term clinical efficacy and safety of BEAS surgery and modified Hanley surgery in HHAF patients from March 2024 to March 2026. Data from the prospective database of this tertiary referral hospital will be used to obtain insights into the clinical outcomes of these surgical treatments. The primary outcome of this study will be the wound healing rate within six months, while the secondary outcomes will include the time to return to work, the maximum visual analogue scale pain score (VAS-PS) within 1-5 days postsurgery, and the Cleveland Clinic Florida Incontinence Score (CCF-IS) and Quality of Life in Anal Fistula Questionnaire Score (QoLAF-QS) at 1, 3, and 6 months postsurgery. Moreover, logistic regression analysis will be used to explore the risk factors for anal fistula recurrence after the BEAS procedure. Discussion This will be the first cohort study to evaluate the differences in therapeutic outcomes between patients who undergo BEAS surgery and patients who undergo surgery via the modified Hanley procedure. By conducting a detailed observation of the efficacy and treatment results of these two surgical methods, this study aims to reveal the differences the clinical effectiveness of these approaches and to provide evidence-based support for future randomized controlled trials (RCTs).

Abstract
The best treatment of high complex anal fistula (HCAF) is to avoid anal incontinence while improving the cure rate. On this basis, several surgical procedures for preserving the anal sphincter have been proposed. The purpose of the present study was to evaluate the efficacy and safety of transanal opening of intersphincteric space for treating HCAF. PubMed, Cochrane Library, China National Knowledge Infrastructure and the Wanfang databases were searched to collate all the articles on transanal opening of intersphincteric space for treating HCAF. A total of two researchers independently completed the whole process, from screening and inclusion to data extraction and the data was included in the RevMan 5.3 software for analysis. The main outcomes included the patients' essential characteristics, primary healing rate, management after recurrence, final healing rate, anal incontinence score before and after surgery, postoperative complication rate and types of complications. A total of six articles were included in this meta-analysis. The results showed that the weighted final healing rate of patients following transanal opening of intersphincteric space was 89% [risk differences (RD)=0.89; 95% confidence interval (CI)=0.86-0.92; I2=0%; P<0.00001]. The results of the anal incontinence score showed that there was no significant difference between the results before and after transanal opening of intersphincteric space surgery mean differences [(MD)=-0.04, Cl=-0.10-0.02, I2=0%; P=0.21]. Only 11 patients were reported to have complications, including urinary retention and bleeding following transanal opening of intersphincteric space with a complication rate of 8% (11/138) and the weighted average complication rate was 6% (RD=0.06,95% CI=0.02-0.10; I2=9%; P=0.003). Transanal opening of intersphincteric space has a high cure rate, a favorable anal incontinence score, fewer types of postoperative complications and a low complication rate; it can be used as a minimally invasive and sphincter-preserving surgical method for treating HCAF and is worthy of further promotion and research in clinical practice.

Abstract
Anal fistula can be a challenging condition to manage, with complex fistulas presenting even greater difficulties. The primary concerns in treating this condition are a risk of damage to the anal sphincters, which can compromise fecal continence, and refractoriness to treatment, as evidenced by a high recurrence rate. Furthermore, the treatment of complex anal fistula involves several additional challenges. Satisfactory solutions to many of these obstacles remain elusive, and no consensus has been established regarding the available treatment options. In summary, complex anal fistula has no established gold-standard treatment, and the quest for effective therapies continues. This review discusses and highlights groundbreaking advances in the management of complex anal fistula over the past decade.

Abstract
Anal fistulas, especially complex and high fistulas, are difficult to manage. The transanal opening of the intersphincteric space (TROPIS) procedure was first described in 2017, and a high success rate of over 90% was reported in high complex fistulas. Since then, more studies and even a meta-analysis have corroborated the high efficacy of this procedure in high fistulas. Conventionally, the main focus was to close the internal (primary) opening for the fistula to heal. However, most complex fistulas have a component of the fistula tract in the intersphincteric plane. This component is like an abscess (sepsis) in a closed space (2 muscle layers). It is a well-known fact that in the presence of sepsis, healing by secondary intention leads to better results than attempting to heal by primary intention. Therefore, TROPIS is the first procedure in which, instead of closing the internal opening, the opening is widened by laying open the fistula tract in the intersphincteric plane so that healing can occur by secondary intention. Although the drainage of high intersphincteric abscesses through the transanal route was described 5 decades ago, the routine utilization of TROPIS for the definitive management of high complex fistulas was first described in 2017. The external anal sphincter (EAS) is completely spared in TROPIS, as the fistula tract on either side of the EAS is managed separately-inner (medial) to the EAS by laying open the intersphincteric space and outer (lateral) to the EAS by curettage or excision.

Abstract
INTRODUCTION This systematic literature review (SLR) assessed incidence/prevalence of cryptoglandular fistulas (CCF) and outcomes associated with local surgical and intersphincteric ligation procedures for CCFs. METHODS Two trained reviewers searched PubMed and Embase for observational studies evaluating the incidence/prevalence of cryptoglandular fistula and clinical outcomes of treatments for CCF after local surgical and intersphincteric ligation procedures for CCF. RESULTS In total 148 studies met a priori eligibility criteria for all cryptoglandular fistulas and all intervention types. Of those, two assessed incidence/prevalence of cryptoglandular fistulas. Eighteen reported clinical outcomes of surgeries of interest in CCF and were published in the past 5 years. Prevalence was reported as 1.35/10,000 non-Crohn's patients, and 52.6% of non-IBD patients were found to progress from anorectal abscess to fistula over 12 months. Primary healing rates ranged from 57.1% to 100%; recurrence occurred in a range of 4.9-60.7% and failure in 2.8-18.0% of patients. Limited published evidence suggests postoperative fecal incontinence and long-term postoperative pain were rare. Several of the studies were limited by single-center design with small sample sizes and short follow-up durations. DISCUSSION This SLR summarizes outcomes from specific surgical procedures for the treatment of CCF. Healing rates vary according to procedure and clinical factors. Differences in study design, outcome definition, and length of follow-up prevent direct comparison. Overall, published studies offer a wide range of findings with respect to recurrence. Postsurgical incontinence and long-term postoperative pain were rare in the included studies, but more research is needed to confirm rates of these conditions following CCF treatments. CONCLUSION Published studies on the epidemiology of CCF are rare and limited. Outcomes of local surgical and intersphincteric ligation procedures show differing success and failure rates, and more research is needed to compare outcomes across various procedures.

Abstract
Anal fistulas are common anorectal conditions, and surgery is the primary treatment option. In the last 20 years of literature, there exist a large number of surgical procedures, especially for the treatment of complex anal fistulas, as they present more recurrences and continence problems than simple anal fistulas. To date, there are no guidelines for choosing the best technique. We conducted a recent literature review, mainly the last 20 years, based on the PubMed and Google Scholar medical databases, with the goal of identifying the surgical procedures with the highest success rates, lowest recurrence rates, and best safety profiles. Clinical trials, retrospective studies, review articles, comparative studies, recent systematic reviews, and meta-analyses for various surgical techniques, as well as the latest guidelines of the American Society of Colon and Rectal Surgeons, the Association of Coloproctology of Great Britain and Ireland, and the German S3 guidelines on simple and complex fistulas were reviewed. According to the literature, there is no recommendation for the optimal surgical technique. The etiology, complexity, and many other factors affect the outcome. In simple intersphincteric anal fistulas, fistulotomy is the procedure of choice. In simple low transsphincteric fistulas, the patient's selection is crucial in order to perform a safe fistulotomy or another sphincter-saving technique. The healing rate in simple anal fistulas is higher than 95% with low recurrence and without significant postoperative complications. In complex anal fistulas, only sphincter-saving techniques should be used; the optimal outcomes are obtained by the ligation of the intersphincteric fistulous tract (LIFT) and rectal advancement flaps. Those techniques assure high healing rates of 60-90%. The novel technique of the transanal opening of the intersphincteric space (TROPIS) is under evaluation. The novel sphincter-saving techniques of fistula laser closure (FiLac) and video-assisted anal fistula treatment (VAAFT) are safe, with reported healing rates ranging from 65% to 90%. Surgeons should be familiar with all sphincter-saving techniques in order to face the variability of the fistulas-in-ano. Currently, there is no universally superior technique that can treat all fistulas.

Abstract
INTRODUCTION Anal fistula is the natural evolution of perianal abscess and one of the most common perianal diseases for adults. For complex fistula, it is still very challenging for anorectal surgeons to manage. With the introduction of laser technique in surgery, it is becoming more and more widely used for the treatment of cryptoglandular anal fistula. During the past decade, numerous studies have reported the clinical effectiveness and postoperative outcomes of different forms of laser treatment for anal fistula. However, as these studies were varied in terms of baseline characteristics, the evidence for the true clinical effectiveness of laser treatment for anal fistula need further critical appraisal. Therefore, the purpose of this study is to evaluate the outcomes of surgical laser therapy for cryptoglandular anal fistula stratified by laser type and Parks' classification through a synthesis of quantitative and qualitative evidence. METHODS AND ANALYSIS This study will be carried out with adherence to the Cochrane Handbook. We will search PubMed, Cochrane Library, and Embase until June, 2022 to identify all relevant interventional and observational studies examining the effects of laser therapy on the clinical outcomes for cryptoglandular anal fistula. Data extraction from eligible studies will be performed independently by two unblinded authors using standardized extraction forms. Risk of bias assessment for each study will be conducted using Cochrane tool for randomized controlled trials (RCTs) and the Newcastle-Ottawa scale (NOS) tool for observational studies. The DerSimonian-Laird random-effects model will be used to calculate the pooled estimates. Heterogeneity will be examined by subgroup analysis stratified by laser type and Parks' classification and other study characteristics. Potential publication bias will be assessed by funnel plot symmetrical and Egger's regression tests. CONCLUSIONS The synthesis of quantitative and qualitative evidence of this systemic review will yield updated and comprehensive evidence of laser treatment on specific outcomes, which can provide anorectal surgeons with high level evidence-based recommendations to improve patient care and clinical outcomes.

Abstract
AIM The aetiology of anal fistula has not been fully clarified. One of the causes of anal fistulas may be the markedly deep crypts that characterize the primary openings. We developed subcutaneous incision of the fistula tract and internal sphincterotomy (SIFT-IS) to eradicate these deep crypts. The aim of this study was to evaluate outcomes in patients with anal fistula treated with SIFT-IS. METHOD A retrospective study was performed over a 2-year period. Patients with transsphincteric anal fistula who underwent SIFT-IS were enrolled. The primary endpoint was the anal fistula healing rate at 16 weeks postoperatively. The secondary endpoints were healing time, postoperative complications and clinical continence status. RESULTS One hundred and fifty one patients were enrolled. Primary healing was accomplished in 129 patients (85%). There were 17 patients (11%) with a remnant fistula and five (3%) with a recurrence. The remnant fistulas healed spontaneously at more than 16 weeks postoperatively in seven patients. The median healing time was 6 (3-96) weeks. Surgical intervention was required in seven patients with a remnant fistula and four with recurrence. At the final follow-up, the wounds had healed in 148 patients (98%). No significant postoperative complications or incontinence were observed. CONCLUSION Subcutaneous incision of the fistula tract and internal sphincterotomy is a promising surgical option for transsphincteric anal fistulas, with a satisfactory healing rate.

A total of 156 patients clinically diagnosed with complex anal fistula from January 2020 to December 2021 were studied and randomly divided into an experimental group (n = 82) and a control group (n = 74). Patients in the experimental group were examined by percutaneous fistula CEUS combined with CEUS + 360°-TRUS, while patients in the control group were examined using TRUS. The detection of fistulas (main tract, branch and internal orifice) and the accuracy of Parks classification were compared between the two groups. Recurrences were followed up at 1, 3 and 6 mo after the surgery. A total of 156 patients were included, aged 23-68 y (average: 37.7 ± 18.2 y). In both groups, the course of disease was <1 mo in 128 cases, 1-2 mo in 22 cases and >3 mo in 6 cases. A total of 474 fistulas were confirmed by surgery in the aforementioned patients, including 224 main fistulas, 250 branch pipes and 254 internal orifices. The CEUS + 360°-TRUS group had 96.87%, 90.41% and 90.14% diagnostic accuracy for the main tract, branch and internal orifice, which was statistically significant (p < 0.001) compared with the 85.00%, 70.00% and 72.46% for the TRUS group, respectively. The overall accuracy of Parks classification of anal fistula in the CEUS + 360°-TRUS group was significantly higher than that in the TRUS group (90.24% vs. 78.38%, p < 0.001). After 6 mo of follow-up, the recurrence rate in the CEUS + 360°-TRUS group was 4.87%, and the recurrence rate in the TRUS group was 18.91%. Percutaneous fistula CEUS combined with transrectal 360° 3-D imaging has significantly higher accuracy than conventional TRUS in the diagnosis of complex anal fistula, especially for anal fistula branches, internal openings and Parks classification and is beneficial in reducing post-operative occurrence of complex anal fistulas.

Zhang C, Zhang X, Zhao X, Zhu Y, Zhang D, Li H. The Value of Transrectal Ultrasound in the Preoperative Diagnosis of Complex Anal Fistula (CAF): Based on a Retrospective Cohort Study. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:6411935. [PMID: 35685902 PMCID: PMC9173950 DOI: 10.1155/2022/6411935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/04/2022] [Accepted: 04/09/2022] [Indexed: 11/17/2022]
Abstract
Objective A case-control study was employed to retrospectively analyze the value of transrectal ultrasound in the preoperative diagnosis of complex anal fistula (CAF). Methods The clinical data of 128 patients with CAF treated in our hospital from March 2019 to June 2021 were analyzed retrospectively. All patients were examined by transrectal ultrasound and MRI with Hitachi HI Vision Ascendus ultrasound diagnostic apparatus and MRI. The general data of the patients (age, sex, course of disease, complications, and previous operation history) and ultrasonic image characteristics were recorded. The consistency of internal orifice, head, branch/abscess, and abscess detected by ultrasound, MRI, and ultrasound combined with MRI were compared, and the sensitivity, accuracy, and specificity of ultrasound, MRI, and the combination of ultrasound and MRI (ultrasound+MRI) in the diagnosis of different Parks classification of anal fistula (AF) were compared. Results The ultrasound images of the rectal probe in typical cases were compared with the MRI images. The characteristics of the ultrasound images were as follows: the outer orifice of AF was a thin strip of mixed echo or low echo leading to the skin side, and the inner orifice showed local dilated low echo, mixed echo, or interruption of mucosal continuity. The following are the MRI image features: abnormal long bar signal shadow from the dorsal side of the end of the coccyx to the S5 plane, low signal on T1WI, high signal on T2WI, blurred boundary, uneven signal, bifurcation in the lower end of the tail for "Y" shape, one branch opening at the body surface at about 6 o'clock, the other walking horizontally, passing through the levator ani muscle to the right posterior position of the rectum at about 6:00 o'clock, and penetrating the inner mouth of the rectum at 6 o'clock. The detection of internal orifice, head, branch/abscess, and abscess were compared by three examination methods. There was significant difference in the detection rate of internal orifice and branch/purulent cavity among the three methods (P < 0.05). The detection rates of internal mouth and branch/abscess cavity by ultrasound and MRI (94.77% and 94.94%) were higher than those by single ultrasound (75.16% and 79.78%) and MRI (81.05% and 83.15%) (P < 0.05). There was no significant difference in the detection rate of ultrasound, MRI internal orifice, and branch/purulent cavity (P > 0.05). There was no significant difference in the detection rate of supervisor and abscess among the three methods (P > 0.05). The results of operation included transsphincter type (n = 53), intersphincter type (n = 45), and superior sphincter type (n = 30). Analysis of transsphincter type AF detected by three methods: 42 cases of transsphincter type AF and 86 cases of nonsphincter type AF were detected by ultrasound, 36 cases of transsphincter type AF and 92 cases of nontranssphincter type AF were detected by MRI, 57 cases of transsphincter type AF and 71 cases of nonsphincter type AF were detected by ultrasound and MRI. The comparison of the efficacy of the three methods in the diagnosis of transsphincter AF and the sensitivity of the three methods in the diagnosis of transsphincter AF showed significant difference (P < 0.05). The sensitivity of ultrasound and MRI in the diagnosis of transsphincter AF (96.23%) was higher than those of single ultrasound (67.92%) and MRI (64.15%) (P < 0.05). There was no significant difference in the accuracy and specificity of the three methods in the diagnosis of transsphincter AF (P > 0.05). There were 41 cases of intersphincter type AF and 87 cases of nonsphincter type AF detected by ultrasound, 38 cases of intersphincter type AF and 90 cases of nonsphincter intersphincter type AF detected by MRI, and 45 cases of intersphincter type AF and 83 cases of nonsphincter intersphincter type AF detected by ultrasound and MRI. The sensitivity and accuracy of the three methods in the diagnosis of intersphincter AF were statistically significant (P < 0.05). The sensitivity and accuracy (100.00% and 100.00%) of ultrasound and MRI in the diagnosis of intersphincter AF were higher than those of single ultrasound (66.67% and 79.69%) and MRI (71.11% and 85.16%) (P < 0.05). There was no significant difference in the specificity of the three methods in the diagnosis of intersphincter AF (P > 0.05). The results of three methods were compared, including 24 cases of superior sphincter type AF and 89 cases of nonsuperior sphincter type AF, 21 cases of superior sphincter type AF, and 107 cases of nonsuperior sphincter type AF detected by MRI and 93 cases of superior sphincter type AF and 128cases of nonsuperior sphincter type AF detected by ultrasound and MRI. There was no significant difference in the sensitivity, accuracy, and specificity of the three methods in the diagnosis of superior sphincter AF (P > 0.05). Conclusion The sphincter, anorectal, and surrounding tissues were clearly demonstrated by transrectal ultrasound. The internal orifice, head, branch/abscess, abscess, and the relationship between abscess and sphincter in the diagnosis of CAF were in good agreement with the surgical results. Ultrasound+MRI can take into account the advantages of ultrasound and MRI, make up for each other, and improve the detection rate of internal orifice and branch/abscess. It can improve the sensitivity of diagnosis of transsphincter AF and the sensitivity and accuracy of intersphincter AF, which can provide intuitive and valuable imaging information for surgical intervention.

Abstract
BackgroundThe internal orifice plays an important role in the pathogenesis and treatment of the most complex fistula-in-ano. The treatment of the internal orifice is considered to be the key to the success of anal fistula surgery. The objective of this study is to evaluate the feasibility of a new sphincter-sparing surgical approach for anal fistula.Materials and MethodsAll hospitalized anal fistula patients were included in this study. Preoperative anorectal ultrasound was done on all the patients. Transanal internal orifice alloy closure (IOAC) was performed through a disposable titanium nickel alloy anal fistula stapler. The external sphincter was not cut. An anal fistula brush was used to curette and clean fistulas. Postoperative anorectal color ultrasound was used for evaluation 2 months postoperatively.ResultsTwenty-one patients (male/female: 18/3, age: 39.7 ± 10.5 years) with fistula-in-ano were included (follow-up: 6–11 months).In total, 38.1% (8) had multiple tracts, and 9.5% (2) belonged to a high anal fistula. In total, 23.8% (5) of anal fistula patients were complicated by Crohn’s disease. The fistula healed completely in 85.7% (18/21) and did not heal in 14.3% (3/21). Three patients who did not heal had conventional surgery reperformed and eventually healed. Except for three patients undergoing additional traditional anal fistula surgery, the Wexner incontinence scores of other patients did not change after surgery compared with before surgery.ConclusionsIOAC is a novel sphincter-saving technique that is simply effective in treating anal fistula containing Crohn’s anal fistula.

Abstract
This study aimed to compare the efficacy between decompression and drainage seton (DADS) and cutting seton (CS) in the treatment of high complex anal fistula. Patients were randomly assigned 1:1 to DADS or CS group. The primary outcome was the rate of wound healing. Second outcomes included time taken to return to work, postoperative pain, the severity of fecal incontinence and other complications. A total of 120 patients with a mean age of 39 years were included. There was no significant difference in the rate of complete wound healing at 1 year. The mean time taken to return to work was 5 ± 2 days in DADS group, shorter than CS group (10 ± 3, p < 0.001). Mean vaizey incontinence score and the post-operation pain in DADS group was significantly lower than CS group. No significant difference was found between two groups in the incidence of complications. DADS is as effective as Cutting seton for the treatment of high complex anal fistula but is associated with less postoperative pain and better sphincter function preserving.

Abstract
INTRODUCTION Supralevator fistula-in-ano are difficult to manage. If these fistulas have an additional supralevator internal-opening in rectum apart from the primary internal-opening at the dentate line, then the management becomes even more difficult. There is no literature/guidelines available on the management of supralevator rectal opening (SRO). METHODS All consecutive supralevator fistula-in-ano patients having a SRO were retrospectively analyzed. The operative management of SRO in these fistulas was reviewed. All the fistulas were managed by the same procedure, transanal opening of intersphincteric space (TROPIS). The latter was a modification of LIFT (ligation of intersphincteric tract) procedure in which the intersphincteric tract was opened-up in the rectum rather than ligated (as is done in LIFT). The SRO was managed in three ways, group-1:SRO was laid-open into the rectum in continuity with the primary opening at dentate line, group-2:the mucosa around SRO was cauterized, group-3:nothing could be done to SRO. RESULTS Out of 836 patients operated between 2015 and 2020, 138 patients (16.5%) had supralevator extension. Amongst these, 23/138 (16.6%) patients had a SRO. 2 patients were excluded (short follow-up) and 21 patients were included in the analysis. 12/13(92%) patients in group-1, 4/5 (80%) patients in group-2 and 2/3(67%) patients in group-3 got healed (p=0.47, Chi-square test). The overall healing rate was 18/21(86%). CONCLUSIONS The supralevator rectal opening (SRO) heals well irrespective of the method utilized. Thus, proper management of the primary opening at the dentate line holds the key to fistula healing and SRO is perhaps not much responsible for persistence of the fistula. However, more studies are needed to corroborate these findings.

Abstract
Background There are many surgical methods of sphincter preservation in treating complex anal fistula, but the therapeutic effects of each operation are different. Therefore, this study aimed to compare the impact of other treatment methods through a network meta-analysis to evaluate the best sphincter preservation method for treating complex anal fistula. Methods We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, VIP Journal Database, and the Wanfang Database to collate randomized controlled trials on sphincter-preserving surgery for complex anal fistula. Results A total of 29 articles were included in this meta-analysis. The cure rates showed no statistically significant differences between any two interventions (P > 0.05). The recurrence rate results showed that the rate of patients after Fistulectomy was higher than others (P < 0.05). The incidence rate of complications showed that the incidence rate after fistulectomy treatment was higher than that of others (P < 0.05). The surface under the cumulative ranking (SUCRA) was used to arrange their advantages and disadvantages, and a larger SUCRA value indicates that the intervention may be more effective. The results showed that TROPIS may have the highest cure rate (SUCRA = 78.6%), stem cell transplantation (SCT) may have the lowest recurrence rate (SUCRA = 85.5%), and imLIFT may have the least complications (SUCRA = 88.2%). Conclusion According to the existing literature data, for patients with complex anal fistula, TROPIS may be the surgical method with the highest cure rate, SCT may be the treatment method with the lowest recurrence rate, and imLIFT may be the surgical method with the lowest incidence of postoperative complications.

Abstract
Introduction Treatment of highly complex anal fistula is still a profound test for a specialist colorectal surgeon. The reasons are directly related to recurrence and incontinence. Aim To evaluate the clinical results of a combined method of intraoperative endoanal ultrasonography (IOEAUS) and transanal opening of the intersphincteric space (TROPIS). Material and methods This study retrospectively included 48 patients with complex anal fistula, all of whom underwent new surgical methods. This operation mainly consists of two steps. Firstly, the type of anal fistula was determined by endoanal ultrasonography (EAUS) or magnetic resonance imaging (MRI) before the operation. Then the TROPIS procedure was performed with the help of EAUS, and the decision on whether a drainage seton should be placed depended on the condition of the tract. If there were secondary tracts, they were found and the same was done. Results The median follow-up was 12 months. Two (4.1%) patients experienced recurrence. Four (8.3%) patients did not have primary healing. All 6 patients underwent the same procedure again, and three recovered completely. So total successful fistula healing was observed in 45 (93.7%). There were no major complications and no significant deterioration in anal function and incontinence postoperatively. Conclusions Combined IOEAUS and TROPIS is an effective procedure in the treatment of highly complex anal fistula, and it may offer a new means for other operations.

Abstract
Objectives: Extreme horseshoe anal fistulas are rare, and there are little data on the diagnosis and management of these fistulas. Materials and Methods: Patients with horseshoe anal fistula, in which the fistula tract encircled more than 75% of the anal circumference were included in the study. All patients were assessed by a preoperative magnetic resonance imaging (MRI). The patients were managed by a sphincter-sparing procedure. The continence was evaluated by an objective continence scoring system (Vaizey's scores). Results: 1059 anal fistula patients were operated on over 7-years with a median follow-up of 36 months (range: 5–79 months). There were 47/1059 (4.4%) patients with extreme horseshoe anal fistulas. In 4/47 patients, the fistulas were complete circumanal (encircling anal canal completely). The mean age was 39.5 ± 10.9 years, M/F-41/6. The fistula was supralevator in 12/47 (25.5%), had an associated abscess in 28/47 (59.6%), and was recurrent in 33/47 (70.2%) patients. The tracts were intersphincteric in 27/47, transsphincteric in 2/47, and both (intersphincteric and transsphincteric) in 18/47 patients. All patients (n = 47) were managed by a sphincter-sparing procedure. Four patients were lost to follow-up. The fistula healed completely in 34/43 (79%) patients. There was no significant difference between preoperative and postoperative Vaizey's continence scores 0.031 ± 0.17 and 0.033 ± 0.18 respectively (P=0.90, Mann–Whitney U-test). Conclusion: Extreme horseshoe fistulas are rare, with an incidence of about 4% (in a referral practice). The missed diagnosis of circumferential tracts could lead to a recurrence. MRI was pivotal to confirm the diagnosis. Proper identification and management of internal opening and adequate drainage of all tracts were crucial for successfully treating extreme horseshoe fistulas.

Abstract
Conventionally, in the pathophysiology of anal fistulas, there is only one space considered significant for the spread of pus in the sphincter complex: the intersphincteric space. However, with increasing experience in the high-resolution MRI, and more focus being given on managing fistulas through the intersphincteric space, two additional pathways of fistula spread have been identified. First is a newly described space labelled as the outer-sphincteric space. Second is a known anatomical space (inner intersphincteric space), but this space was considered as irrelevant from the point of view of fistula spread. The conventional intersphincteric space is present in between these two spaces and is referred as 'middle intersphincteric space' in this paper. These three distinct spaces have significant clinical implications as the pattern of spread of pus is quite different in each space, and the management also differs for fistula tract in each of these spaces.

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
Cryptoglandular perianal fistula is a common benign anorectal disorder that is managed mainly with surgery. A fistula is typically defined as a pathological communication between two epithelialized surfaces. More specifically, perianal fistula manifests as an abnormal tract between the anorectal canal and the perianal skin. Perianal fistulas are often characterized by significantly decreased patient quality of life. The cryptoglandular theory of perianal fistulas suggests their development from the proctodeal glands, which originate from the intersphincteric plane and perforate the internal sphincter with their ducts. Involvement of proctodeal glands in the inflammatory process could play a primary role in the formation of cryptoglandular perianal fistula. The objective of this narrative review was to investigate the current knowledge of the pathogenesis of cryptoglandular perianal fistula with the specific aims of characterizing the potential role of proinflammatory factors responsible for the development of chronic inflammation. Further studies are crucial to improve the therapeutic management of cryptoglandular perianal fistulas.

Abstract
AIM Sepsis in the intersphincteric plane behaves like an abscess in a closed space and is present in most complex fistulas. Ignoring this sepsis is a cause of recurrence. Complex fistulas can be successfully managed by transanal opening of the intersphincteric space (TROPIS) into the anal canal. The long-term efficacy of the TROPIS procedure was analysed in an exclusive cohort of high complex anal fistulas. METHODS All consecutive patients operated for a high complex fistula-in-ano were included prospectively. Preoperative MRI scans were obtained for all the patients. The intersphincteric space and internal opening was laid open into the anal canal while preserving the external sphincter. The external tracts were thoroughly curetted and cleaned. Fistula healing rate and objective incontinence scores (preoperatively and during long-term follow-up) were analysed. RESULTS A total of 325 patients (age 39.9 ± 10.9 years, 292 men) were operated with TROPIS and had a follow-up of 7-67 months (median 36 months). In the cohort, 67.4% (219) had recurrent fistulas, 82.8% (269) had multiple tracts, 36.3% (118) had horseshoe tracts, 37.5% (122) had associated abscesses and 24% (78) were supralevator fistulas. Nineteen patients were excluded. Fistulas healed completely in 78.4% (240/306) of patients and did not heal in 21.6% (66/306) of patients. 36/66 of these patients were operated again and the fistulas healed in 28 patients. Thus, the overall healing rate was 87.6% (268/306). The mean preoperative and postoperative incontinence scores were 0.085 ± 0.35 and 0.119 ± 0.48 respectively (P = 0.38). The healing rate of fistulas with associated acute abscesses was similar to the fistulas without abscesses (87% vs. 88%, P = 0.85). CONCLUSION Transanal opening of the intersphincteric space is a safe and highly effective sphincter-sparing procedure to manage high complex fistulas-in-ano.

[PMID: 33875192 DOI: 10.1016/j.ciresp.2021.03.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 03/17/2021] [Accepted: 03/17/2021] [Indexed: 12/14/2022]
Abstract
INTRODUCTION Supralevator fistula-in-ano are difficult to manage. If these fistulas have an additional supralevator internal-opening in rectum apart from the primary internal-opening at the dentate line, then the management becomes even more difficult. There is no literature/guidelines available on the management of supralevator rectal opening (SRO). METHODS All consecutive supralevator fistula-in-ano patients having a SRO were retrospectively analyzed. The operative management of SRO in these fistulas was reviewed. All the fistulas were managed by the same procedure, transanal opening of intersphincteric space (TROPIS). The latter was a modification of LIFT (ligation of intersphincteric tract) procedure in which the intersphincteric tract was opened-up in the rectum rather than ligated (as is done in LIFT). The SRO was managed in three ways, group-1:SRO was laid-open into the rectum in continuity with the primary opening at dentate line, group-2:the mucosa around SRO was cauterized, group-3:nothing could be done to SRO. RESULTS Out of 836 patients operated between 2015 and 2020, 138 patients (16.5%) had supralevator extension. Amongst these, 23/138 (16.6%) patients had a SRO. 2 patients were excluded (short follow-up) and 21 patients were included in the analysis. 12/13(92%) patients in group-1, 4/5 (80%) patients in group-2 and 2/3(67%) patients in group-3 got healed (p=0.47, Chi-square test). The overall healing rate was 18/21(86%). CONCLUSIONS The supralevator rectal opening (SRO) heals well irrespective of the method utilized. Thus, proper management of the primary opening at the dentate line holds the key to fistula healing and SRO is perhaps not much responsible for persistence of the fistula. However, more studies are needed to corroborate these findings.

Abstract
Anal fistula, with its complicated pathogenesis, has been considered as a clinical challenge for centuries. The risk of frequent recurrence and incontinence constitutes a considerable threat in the long-term treatment of anal fistula. In this work, we narratively reviewed the scientific literature of new techniques that have been used for anal fistula treatment over the recent 5 years, objectively evaluated the pros and cons of each technique on the basis of clinical outcomes, and tried to disclose the effective strategies for anal fistula treatment. Up to date, surgery is the main method used for treating anal fistula, but there is no simple technique that can completely heal complex anal fistula. In the course of surgery treatment, the healing outcome, and the protection of anal function should be weighed comprehensively. Among the innovative techniques that have emerged in recent years, combined techniques based on drainage Seton and LIFT-plug seem to be the relatively effective therapies, but their effectiveness requires more multi-center prospective randomized controlled trials with large sample size and long-term follow-up to be validated.

Abstract
Purpose In some anal fistulas, the internal/primary opening cannot be located even after examination and assessment on MRI or transrectal ultrasound. The efficacy of a simple new protocol to manage such therapeutically challenging fistulas was tested. Patients and Methods All anal fistula patients operated consecutively over 7 years were included in the study. A simple two-step protocol was followed for fistulas in which the internal opening was not locatable after clinical examination and MRI assessment. First, the MRI was reassessed. The site where the fistula was closest to the internal sphincter was noted. It was assumed that the internal-opening was located at that position and the fistula was treated accordingly. Second, in horseshoe anal fistulas with no apparent internal opening, it was assumed that the internal opening was located in the midline. Low fistulas were treated by fistulotomy and high fistulas by a sphincter-sparing procedure. Incontinence was evaluated by objective incontinence scores (Vaizey scores). Results A total of 757 patients were operated (median follow-up-33 months). Of these, 57 patients were excluded due to short or inadequate follow-up. In 154/700 (22%) patients, the internal opening could not be located while in 546/700 (78%), the internal opening was found. Both the groups were similar in all parameters. In the "internal-opening found" group, the fistula healed completely in 486/546 (89%) and in the 'internal-opening not found group', the fistula healed in 140/156 (90.9%) (p=1.01). The objective continence scores did not change significantly after surgery in both the groups. Conclusion This new protocol seems effective as a high cure rate could be achieved in 'internal-opening not found' fistulas which was comparable to fistula healing in the 'internal-opening found' group.

Abstract
BACKGROUND The role of the intersphincteric space in the pathogenesis of fistula-in-ano is being increasingly recognized. Submucosal and intersphincteric rectal abscesses have been surgically managed by laying open and draining the intersphincteric space as well as by the modified ligation of intersphincteric fistula tract (LIFT) procedure. In 2017, the transanal opening of intersphincteric space (TROPIS) technique was reported for the treatment of high, complex anal fistulae. AIM We aim to investigate the advantages of performing the TROPIS procedure in patients with fistula-in-ano. METHODS This was a prospective cohort study investigating the outcomes in patients who had undergone a procedure using the TROPIS technique for the treatment of fistula-in-ano. Preoperative magnetic resonance imaging scans and electronic colonoscopies were performed on all patients. A clinical database evaluating the following variables was constructed: age, gender, body mass index (BMI), previous fistula surgery, type of fistula, postoperative complications, duration of follow-up, success rate, and incontinence scores pre- and postoperatively. RESULTS The TROPIS procedure was performed on 41 patients with fistula-in-ano with a follow-up time of 6-23 months. The characteristics of the patients were as follows: 36 males, 6 females, mean age 38.6±13.2 years, and mean BMI 23.5±3.9 kg·m-2. All patients (41) had transsphincteric fistulae, and 90.2% (37) had high fistula. Of the 41 patients, 22% (9) had recurrent fistulae, 29.27% (12) had horseshoe fistulae, 7.3% (3) had supralevator fistulae, and 14.6% (6) had an associated abscess. The fistula healed completely in 85.3% (35) of patients and failed to heal in 14.7% (6) of patients, and the healing of high fistula was 86.5% (32). Of those patients who had not healed completely, 2 were found to have contracted iatrogenic infections due to foreign residues and underwent surgery with the passing of a loose seton. The additional 4 patients who had not healed underwent a fistulotomy and healed completely thereafter. There were no significant changes in incontinence scores. The incontinence scores were .15 ± .36 preoperatively and .22 ± .47 3 months postoperatively (t = -1.438, P = .16). CONCLUSIONS The TROPIS technique is a novel sphincter-preserving procedure, which can be effectively used in treating fistula-in-ano.

Abstract
Abstract
Background The intersphincteric plane (ISP) is a potential space between the external and the internal anal sphincters. About 90% of the perianal sepsis is caused by an obstruction of the ducts of anal glands with subsequent secondary bacterial infection. The imaging modalities used to diagnose perianal sepsis are the ultrasound via endoanal and transperineal routes and magnetic resonance imaging.
Objective The study aimed to identify the various patterns of the ISP sepsis and their incidence among our study group and to clarify the significance of ISP in the pathogenesis of anorectal abscesses and various types of perianal fistula tracts, to optimize the surgical management.
Methods Retrospective descriptive study in which 57 patients with an ISP sepsis were evaluated with full medical history, clinical exam, and ultrasound; the final diagnosis was based on combining the results of ultrasound, digital rectal examination under anesthesia, and the operative results.
Results The current study showed many patterns of the ISP sepsis and estimated the incidence of each pattern among our study group; such patterns could be fistula tracts, sinus tracts, abscesses, intersphincteric abscess with supralevator extension, sinus with abscess formation, fistula with abscess formation, distension of the ISP with free pus, and other complex patterns like horse abscess, abscess with transsphincteric sinus, and ISP fistula/sinus with transsphincteric branches.
Conclusion Understanding the role of the ISP in the pathogenesis of anorectal abscesses and perianal fistula tracts can help in reaching the optimum way of management.

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 The aim of this study was to investigate the clinical effect of tunnel-like fistulectomy plus draining seton combined with incision of internal opening of anal fistula (TFSIA) in the treatment of high transsphincteric anal fistula. Material/Methods There were 80 patients with high transsphincteric anal fistula randomly divided into TFSIA group and control group, 40 cases in each group. The control group was treated with cutting seton, and the seton was tightened weekly after discharge from the hospital until the seton dropped off. In the TFSIA group, the anal fistula was dissected and resected in tunnel-like form through the external opening to the intersphinceteric space, drained with seton through the tunnel, and cut open the internal opening of the anal fistula and the intersphincteric space and expanded the drainage. The operative time, blood loss, postoperative uroschesis, anal wound pain score, healing time, Wexner anal incontinence score, keyhole-like deformity, and recurrence rate were compared between the 2 groups. Results The differences of the blood loss, operative time, anal wound pain score at 6 hours after operation, postoperative uroschesis and the recurrence rate after operation were not statistically significant (P>0.05), but the TFSIA were better than the control group in the anal wound pain score at 1 week after operation, healing time, Wexner anal incontinence score, and anal keyhole-like deformity rate (P<0.05). Conclusions TFSIA is effective in treating high transsphincteric anal fistula, and it can reduce adverse complications after operation.

Abstract
BACKGROUND Few data are published on perianal tuberculosis. OBJECTIVE This study aimed to determine the best method to diagnose tuberculosis in patients with fistula-in-ano and to conduct a systematic review to determine the incidence and characteristics of tuberculosis fistula-in-ano. DATA SOURCES The prospective study data and existing literature were derived from PubMed, Google scholar, and Scopus STUDY SELECTION:: Prospective analysis of patients with tuberculous fistula-in-ano treated between 2014 and 2018 was conducted, and a systematic review of studies describing ≥3 patients with tuberculosis fistula-in-ano was completed. INTERVENTION Testing of tuberculosis was performed by histopathology or polymerase chain reaction of tissue or pus from the fistula tract. MAIN OUTCOME MEASURES The primary outcomes measured were the detection rate of various tests to detect tuberculosis in fistula-in-ano and the prevalence rate of tuberculosis in simple versus complex fistulas. RESULTS In 637 samples (410 patients) tested, tuberculosis was detected in 49 samples (43 patients). Additional samples (n = 106) sent in patients with a high index of suspicion tested positive in 14 more patients. Thus, overall, 63 samples tested positive in 57 patients (total: 743 samples in 410 patients were tested). Tuberculosis was detected in 2 of 181 patients (1.1%) in tissue (histopathology), in 28 of 341 patients (8.2%) in tissue (polymerase chain reaction), and in 19 of 115 patients (16.5%) in pus (polymerase chain reaction) samples. To detect tuberculosis, tissue (polymerase chain reaction) was significantly better than tissue (histopathology) (28/341 vs 2/181, p < 0.00001) and pus (polymerase chain reaction) was significantly better than tissue (polymerase chain reaction) (19/115 vs 28/341, p < 0.0009). Tuberculosis was significantly more common in complex fistulas than in simple fistulas (20.3% vs 7.2%, p = 0.0002). The systematic review (n = 199) highlighted that tubercular fistulas are more common in recurrent and complex fistulas and in tuberculosis endemic regions. LIMITATIONS The true sensitivity and specificity of each testing modality could not be determined because not all patients with tuberculosis fistula-in-ano were tested by every diagnostic modality studied. CONCLUSIONS The tuberculosis detection rate of polymerase chain reaction was significantly higher than histopathology. Among polymerase chain reaction, pus had higher detection rate than tissue. Tuberculosis was associated with more complex and recurrent fistulas.

Abstract
Fistula-in-ano and pilonidal disease are not known to occur together. In a retrospective study, all patients having fistula-pilonidal disease coexisting simultaneously were included. Out of 1284 patients, 933 were operated (fistula-in-ano, 849; pilonidal disease, 77; and coexisting fistula-pilonidal, 7). A total of 351 patients did not undergo any surgery (two patients had coexisting fistula-pilonidal). Thus, a total of nine patients having coexisting fistula-pilonidal sinus were included in the study (mean age 35.8 ± 19.9 years, M/F 7/2). pIn 6/9 patients, the pilonidal tract was communicating with fistula-in-ano, and in 3/9 patients, they were not communicating/connected. The connection could be established preoperatively with the help of MRI. In all patients with communicating fistula-pilonidal sinus (n=6), the fistula was posterior. 6/9 patients had recurrent fistula and all (9/9) had multiple tracts. The fistula was high and complex in 8/9 patients (grade IV-7, grade V-1). 4/9 patients tested positive for tuberculosis while one patient was suffering from hidradenitis suppurativa. The latter improved on medical treatment. One patient did not agree for surgery and seven were operated. The disease healed in four patients, the disease did not heal in one patient, and two patients were in the convalescent stage. Anal fistula and pilonidal disease can coexist in a same patient and can even be connected. Such diseases are more complex and have a higher incidence of associated diseases like tuberculosis. Magnetic resonance imaging plays a pivotal role in diagnosis. If the connection is missed, the disease treatment becomes difficult.

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

Garg P. Is fistulotomy still the gold standard in present era and is it highly underutilized?: An audit of 675 operated cases. Int J Surg 2018; 56:26-30.

Abstract
AIM Due to fear of incontinence, fistulotomy perhaps remains highly underutilized. The aim was to analyze the efficacy of fistulotomy in a large cohort, to assess the magnitude of underutilization of fistulotomy by current classifications and to identify the subgroup in whom the fistulotomy should be done. METHODS All consecutive operated patients of fistula-in-ano were included in the study retrospectively. The fistulas were classified as per existing classifications-Parks, St James University Hospital (SJUH) and Garg classification. Smaller grades of each classification (Parks I, SJUH I-II, Garg I-II) were expected to be simple fistulas and thus amenable to fistulotomy. Objective incontinence scores were done preoperatively and postoperatively. RESULTS 675 patients were operated over a 5.5 year period (median-27 months). 25 patients were excluded. Fistulotomy was done in 353/650 (54.3%) patients and sphincter-saving procedures (SSP) performed in 297/650 (45.7%) patients. After fistulotomy, 346/353 (98%) fistulas healed after the first operation. Seven patients with recurrent fistula were cured after a repeat fistulotomy surgery. Thus the overall healing rate was 353/353 (100%). There was no significant change in continence scores. The 353 fistulotomy patients were classified as per different classifications- Parks (I-225,II-112,III-16,IV-0), SJUH(I-138,II-87,III-47,IV-65,V-16) and Garg (I-188,II-165,III-0,IV-0,V-0). 123 (36.3%) patients who could undergo fistulotomy successful were erroneously classified as complex fistula by Parks and SJUH classifications. Garg classification accurately identified all 353/353 (100%) patients were amenable to fistulotomy. CONCLUSIONS Fistulotomy is a safe procedure with remarkably high success rate (100%) and is gold-standard in majority of patients (>50%). Parks and SJUH classifications are inaccurate in selecting patients for fistulotomy. Garg classification predicts amenability to fistulotomy with very high accuracy.

Abstract
BACKGROUND Supralevator fistulas are highly complex. The delineation of the supralevator fistula has become accurate because of MRI. OBJECTIVE The aim of the study was to analyze the pathophysiology and treatment of different types of supralevator fistulas. DESIGN This was a prospective study. SETTINGS The study was conducted at a specialized fistula treatment center in North India. PATIENTS All of the patients with fistula-in-ano who presented in the outpatient department were assessed with a physical examination and MRI scan. The patients in whom the supralevator extension was confirmed on MRI were included in the study. MAIN OUTCOME MEASURES The MRI scans of patients included in the study were analyzed in detail to assess the types of supralevator fistulas and other characteristics of these fistulas. The patients who were operated on were followed for cure rate and deterioration in incontinence. RESULTS Of 702 patients with fistula-in-ano who were analyzed by MRI over a period of 3 years, 51 patients with supralevator fistula-in-ano were identified. The mean age was 44.3 ± 12.1 years and the male:female ratio was 16:1. The incidence of supralevator fistulas was 7.26% (51 of 702). In supralevator fistulas, the supralevator extension (upper part) was found to be in the intersphincteric plane in all of the patients. This upper part could be successfully managed by laying it open through the transanal route. The infralevator (lower) part could be of 3 types: intersphincteric (n = 13), low transsphincteric (n = 3), or high transsphincteric (n = 35). The lower part could be managed conventionally. There were no extrasphincteric fistulas. An extensive review of the literature revealed only 2 studies (total fistulas = 16) in which supralevator fistula was studied. LIMITATIONS This was a retrospective study. CONCLUSIONS The upper supralevator extension in all of the supralevator fistulas is almost always in the intersphincteric plane. This upper part could be laid open through the transanal route. The lower infralevator part could be of 3 types, intersphincteric, low transsphincteric, or high transsphincteric, which could be managed conventionally. Thus, supralevator fistulas could be managed successfully and easily. See Video Abstract at http://links.lww.com/DCR/A630.
