Abstract
This is a case of a woman in her 50s with HIV and uncontrolled diabetes who presented to the emergency department with urinary retention and a painful gluteal cleft lesion, admitted for cellulitis. Since initial CT and soft tissue ultrasound (US) were negative for fluid collection, the care team was surprised to find her symptoms continued to progress despite intravenous antibiotics. Finally, MRI 9 days into her admission demonstrated a 12-cm perirectal horseshoe abscess. The patient was ultimately treated with incision and drainage with Penrose drain placement. This case demonstrates the importance of maintaining a high suspicion for horseshoe abscess, a complex form of ischiorectal fossa abscess which can be missed on CT and US imaging, and which may expand rapidly in immunosuppressed patients.

Abstract
OBJECTIVES Perianal fistula is a common disorder characterized by an anomalous perianal track connecting two epithelialized surfaces, most commonly the anal canal and the perianal skin. Although each has its limitations, magnetic resonance imaging (MRI) and endoanal ultrasound are currently two acceptable modalities for assessing perianal fistula. This study aimed to evaluate the accuracy of MRI and endoanal ultrasonography in diagosing perianal fistula, considering the surgical results as the references. METHODS This prospective cohort study was performed on patients with symptomatic perianal fistulas. MRI results of patients reported by the radiologist were collected along with the findings of endoanal ultrasonography performed by a gastroenterologist. These results were compared with surgical findings as the reference standard. RESULTS The study enrolled 126 patients. Exactly 222 definitive fistulas were identified during surgery. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of ultrasound for perianal fistula were 87.38, 38.46, 92.38, 26.31, and 82.25% respectively; and for MRI were 76.12, 57.69, 93.88, 22.05, and 74.19% respectively. The accuracy of endoanal ultrasound for detecting transsphincteric and intersphincteric fistulas was higher than MRI. In contrast, the diagnostic value of MRI for detecting suprasphincteric fistulas was higher than endoanal ultrasound. CONCLUSIONS Using endoanal ultrasonography to diagnose perianal fistulas is a relatively accurate method. This method may be more sensitive than MRI in detecting patients with perianal fistulas and abscesses.

Abstract
Abstract
Objective Despite all the technological advances, successful management of complex fistula-in-ano is still a challenge due to recurrence and incontinence. The present study evaluates the outcomes of a novel technique, Interception of Fistula Track with Application of Ksharasutra (IFTAK) in terms of success rate and degree of incontinence.
Methods In the present prospective study, 300 patients with complex fistula-in-ano were treated by the IFTAK technique, whose surgical steps include: incision at the anterior or posterior midline perianal area, identification and interception of the fistulous track at the level of the external sphincter, rerouting the track (and extensions) at the site of interception, and application of a ksharasutra (medicated seton) in the proximal track (from the site of interception to the internal opening) that is laid open gradually, with the resulting wound healing with minimum scarring. The distal track is allowed to heal spontaneously.
Results There were 227 trans-sphincteric and 73 intersphincteric varieties of fistula with supralevator extension in 23 cases, of which 130 were recurrent fistulas, 29 had horseshoe track, while 25 had blind fistula with no cutaneous opening. The mean duration of the ksharasutra application was 8.11 ± 3.86 weeks with an overall success rate of 93.33% at the 1-year follow-up. A total of 3.67% of the cases reported with a mild impairment of continence on the Wexner incontinence scoring system. Pre- and postoperative anal manometry evaluation showed minimal reduction in median basal and squeeze pressures.
Conclusion The IFTAK technique is a minimally invasive, daycare surgical procedure for the management of complex fistula-in-ano with low recurrence and minimal sphincter damage.

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

Abstract
Hemorrhoids and fistula are considered the most common anorectal conditions in the general population. These conditions affect the quality of a patient's life by causing pain and bleeding during defecation or even in the resting state. Lower grades of hemorrhoids may be controlled by traditional measures. However, surgery is an effective treatment option in recurrent-lower and higher-grade hemorrhoids. Surgical procedures are associated with various complications, including pain and delayed wound healing. Recurrence of hemorrhoids is also a major concern in the post-operative period. An anal fistula is the connection between the anus and the skin and causes severe pain, swelling, as well as blood and pus discharge. Fistula has serious social and economic consequences. Hence, it is important to understand the pathophysiology and molecular pathology of hemorrhoids and fistula, to identify the molecular targets and to develop pharmacological-interventions. In a previous study by our group, the polyherbal formulation Anoac-H was developed for the treatment of different stages of hemorrhoids and fistula, and it was demonstrated that Anoac-H is an effective formulation for treating hemorrhoids. However, the molecular mode of action of Anoac-H on hemorrhoids and fistula had remained elusive. In the present study, it was determined that this formulation reduces the migration of mesenchymal (fibroblasts) and immune (RAW 264.7) cells without affecting their viability. It was also observed that Anoac-H suppresses the expression of regulated upon activation, normal T cell expressed and presumably secreted (RANTES) and VEGF in fibroblasts and macrophages. Inflammation and elevated expression of RANTES and VEGF were observed in hemorrhoids and fistula. However, inflammation, as well as the expression of RANTES and VEGF, were significantly reduced in treated human hemorrhoid and fistula tissues as compared to untreated ones, confirming the in vitro results.

Abstract
Abstract
Background
Fistula in ano is one of the common anorectal disorders which have a tendency to recur specially in complex cases usually due to missed or undetected sepsis at the time of examination or surgery. A correct identification of the primary source of crypt infection along with a complete understanding of the anatomical course of primary and secondary tracks and abscesses is a prerequisite for the successful management of fistula. Preoperative evaluation of fistula in ano using radio-imaging techniques provides a handy insight of fistula anatomy and helps in planning the appropriate treatment strategy. The objective of this article is to review the role of different radio-imaging techniques in the diagnosis and evaluation of fistula in ano along with their advantages and disadvantages over one another.
Main text
A comprehensive literature review was performed searching through the electronic databases as well as the standard textbooks of colorectal surgery. X-rays (plain radiographs and contrast fistulography), computed tomography (CT) scanning, anal endosonography, and magnetic resonance (MR) imaging are the modalities used for preoperative imaging of fistula in ano. Due to low accuracy, X-ray fistulography is not used now for fistula imaging. CT fistulography can be more accurate in cases associated with acute inflammations and abscesses and the fistulas related with inflammatory bowel disease. Anal endosonography and MRI are two of the mostly used and reliable imaging techniques for fistula in ano. Though the use of a 3D technology has improved the accuracy of anal endosonography, MRI is the preferred choice by many. However, various reports have depicted comparable accuracies for both MRI and anal endosonography showing both to be equally sensitive but MRI to be more specific. 3D endoanal ultrasound, on the other hand, is more rapid and can also be used intraoperatively to provide live imaging during surgical exploration.
Conclusion
Complex and recurrent fistula cases should undergo a preoperative imaging to reduce the chances of recurrence. MRI is recommended as the imaging modality of choice for such cases. 3D anal endosonography may however be a good option over MRI owing to its rapidity, availability, and potential of intraoperative assistance during surgery.

Abstract
PURPOSE We determined the outcomes of patients undergoing video-assisted anal fistula treatment (VAAFT) for fistulain-ano at the Philippine General Hospital. METHODS Twenty consecutive adult patients who underwent the VAAFT procedure from 2016-2018 were included in this investigation. Information detailing baseline demographic and clinical data, fistula type and classification, and previous surgeries were retrieved from in-hospital and operative records. Operative time, identification of the internal opening, method of internal opening closure, and occurrence of immediate postoperative complications were determined. The status of the fistula was assessed at one month, 3 months, and 6 months postoperatively based on outpatient follow-up records. The primary outcomes were healing rate and recurrence rate. Secondary outcomes were 30-day morbidity, postoperative complications, and incontinence using the Wexner score. RESULTS Eighteen patients (90%) had a preoperative diagnosis of complex fistula, and 13 patients (65%) had undergone a previous fistula surgery. Primary healing rate was 55% at 1 month, 63.16% at 3 months, and 78.95% at 6 months postoperatively. Eighteen patients (94.74%) maintained continence (Wexner score = 0) at 6 months. CONCLUSION Our study results suggest that VAAFT is a safe, minimally invasive technique for treatment of anal fistula and can preserve anal sphincter function. The technique has an acceptable healing rate with minimal complications.

Abstract
BACKGROUND Fistula-in-ano has a reported incidence of 31-34%. Besides fistulotomy, options for fistula repair are seton placement, endorectal advancement flap (ERAF), fibrin sealant, anal fistula plug and ligation of the intersphincteric fistula tract. Despite having a reported success rate as high as 75-98%, ERAF is not without complications, including flap breakdown, recurrence and fecal incontinence. Traditionally, maintaining a broad base to preserve blood supply has been advocated to reduce flap failure. And the aim of the present study was to evaluate outcomes of adult patients who underwent ERAF for complex fistula-in-ano with the use of intraoperative fluorescence angiography (FA) at our institution between July 2014 and July 2016. METHODS We retrospectively reviewed consecutive cases of complex fistula-in-ano repair with ERAF and FA from a prospectively maintained dataset of adult patients with complex fistula-in-ano. Demographics, intraoperative data and 60-day outcomes were recorded and reviewed. RESULTS Six patients [five males and one female with a mean age of 40 years (range 25-46 years)], with a total of seven fistulas, were identified. Six (85.7%) of these patients had undergone prior surgery for fistula-in-ano. No recurrences or complications of any type were noted at 2-week and 8-week follow-up. The majority of patients (71.4%) required flap revision based on intraoperative FA prior to flap fixation. CONCLUSIONS FA is safe and offers real-time assessment of flap perfusion prior to and after fixation in anal fistula repair. The rate of flap ischemia may be underestimated, and therefore, to improve outcomes in ERAF, intraoperative FA should be included in the surgical armamentarium.
