Background: Anal fistula is an abnormal communicative small channel that has an internal opening and an external opening and connected by the primary track. Our study evaluate the effectiveness of seton in high variety anal fistula.Objectives: Evaluation the efficacy and safety of seton as surgical management of high anal fistula. Methods: This is a prospective study done on 57 patients in BIRDEM hospital and some other clinic of Dhaka city in 3 years period with high variety of anal fistula which is above the dentate line and were treated with seton .Outcome measured during follow up period were- successfully healed, recurrence, incontinence, percentage of complications and patients satisfaction.Result: Among 57 patients mean age was 38.2+_6.8 years. Overall outcome of the patients showed-fistula completely healed in 51 patients, incontinence occurred in 2 patients and recurrence occurred in 4 patients.Conclusion: Seton is relatively safe, effective and low cost for the management of high anal fistula with low rate of incontinence. It can therefore, be recommended as the standard of treatment for high variety fistula in ano.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 100-104

Introduction: 360° endoanal ultrasound (EAUS) has become an effective imaging tool to diagnose anal fistulas for last three decades. Objectives: To assess the diagnostic accuracy of 360° endoanal ultrasound imaging comparing pre and peroperative diagnosis in anal fistulas. Methods: Between Jauary 2015 and June 2018, 240 patients with clinical anal fistula underwent endoanal sonographic assessment using a 360° endoanal transducer (7–15 MHz The sonographic findings, including the fistulas and other inflammatory lesions, were correlated with surgical results. The types of fistulas on endoanal sonography based on classification of Park and the internal opening of the fistula, both pre and peroperative, were compared to those of other studies. Results: The 240 patients studied included 165 male and 75 female patients. Endoanal sonography was able to show and track hypoechoic lesions, their locations, and internal openings of the fistulas. Compared with surgical results, endoanal sonography had sensitivity of 94.6%, specificity of 100%, and accuracy of 94.1% for the diagnosis of perianal fistulas. Also, endoanal sonography had accuracy of 86.1% for determining fistula types based on the Parks classification and 92.8% for identifying internal openings of the fistulas. Conclusions: Endoanal ultrasound is an accurate and noninvasive imaging modality for evaluation of fistulas. It is a very useful tool for preoperative management and surgical planning by providing precise and detailed information on fistulas. J Shaheed Suhrawardy Med Coll, December 2018, Vol.10(2); 66-69

Background Promotion of healing of the anal wound after fistulotomy may help accelerate recovery and return to work. The present study aimed to assess the effect of marsupialisation of the edges of the laid open fistula track on wound healing after anal fistulotomy for simple anal fistula. Methods This was a prospective randomised trial on patients with simple anal fistula. Patients were randomly assigned to one of two groups; group I underwent anal fistulotomy and group II underwent anal fistulotomy and marsupialisation of the edges of the laid open track. Outcomes of the study were time to achieve complete wound healing, operation time, postoperative pain and complications. Results Sixty patients of mean age of 40.8 years with simple anal fistula were randomly divided into two equal groups. No significant differences between the two groups regarding operation time (16.8 vs 18.4 minutes; P = 0.054), postoperative pain score (1.6 vs 1.2; P = 0.22), and complication rates were recorded. Group II achieved complete healing in a significantly shorter duration than group I (5.1 vs 6.7 weeks; P < 0.0001). Conclusion Marsupialisation of the edges of the laid open fistula track after fistulotomy resulted in quicker wound healing with similar complication and recurrence rates to lay open fistulotomy alone.

High Perianal Fistula

Abstract When the track reaches the skin or another epithelialized surface then a fistula is formed. Anal fistula were classified on the basis of its relationship to the sphincters. The definition of high or low describes the height of the track as it traverses the sphincter muscles and not the position of the internal opening which is almost without exception at the dentate line. More accurately according to parks classification fistula in ano can result in an abscess between the internal and external sphincters, which in turn can spread to other parts of the perianal region. Infection can then track in many directions from this focus in the intersphincteric plane. Background Anal fistula is an abnormal communicative small channel that has an internal opening and an external opening and connected by the primary track. Our study evaluate the effectiveness of seton in high variety anal fistula. Objectives Evaluation the efficacy and safety of seton as surgical management of high anal fistula. Methods: This is a prospective study done on 30 patients in ELNile hospital in one Year period with high variety of anal fistula which is above the dentate line and were treated with seton .Outcome measured during follow up period were- successfully healed, recurrence, incontinence, percentage of complications and patients satisfaction. Result Among 30 patients mean age was 42.2+_6.8 years. Overall outcome of the patients showed-fistula completely healed in 27 patients, incontinence occurred in 3 patients and recurrence occurred in 3 patients. Conclusion Seton is relatively safe, effective and low cost for the management of high anal fistula with low rate of incontinence. It can therefore, be recommended as the standard of treatment for high variety fistula in ano.

Background: Anal fistulas are one of the commonest causes for a persistent discharge seropurulent in nature that irritates the skin in the neighbourhood and leads to discomfort. Fistula-in-ano is seen quite frequently in perirectal perianal suppuration. The objective of this study to study the clinical profile and diagnosis of anal fistula at surgical OPD of VDGIMS.Methods: The present cross-sectional observational study was carried out in patients with fistula-in-ano admitted at surgical department of VDGIMS, Latur during the period of 2017-19 in 50 diagnosed patients. Data was analysed by using SPSS 24.0 version IBM USA.Results: Majority of the patients with anal fistula were from 41-50 years age group i.e. 15 (30%) and males were predominantly affected 40 (80%) compared to females i.e. 10 (20%). Male to female ratio was 4:1. Perianal discomfort was the commonest symptom in all patients i.e. 100%. It is followed by perianal discharge complained by 54% and perianal itching in 38% cases. The anterior position of external opening is found to be significant (p<0.05). Fistulogram showed external opening in all patients i.e. 50 cases whereas internal opening in 46 (92%) cases. Findings of MRI revealed that anal fistula was intra sphincteric in 28 cases i.e. 56%, extra sphincteric in 2 cases i.e. 4% and trans sphincteric in 20 cases i.e. 40%.Conclusions: Commonest age group affected in our study was 40-50 years with male predominance. Perianal discomfort and discharge were the commonest symptom. E. coli was the predominant organism isolated. Fistulogram and MRI is useful in detecting the aetiology of fistula in ano.

Abstract A case of anal fistula communication to anterior abdominal wall treated using ‘Medicated Seton’ called ‘Ksharasutra’ is reported here. Sushruta mentioned about Ksharasutra in his text book Sushruta Samhita in 500 BC. A 54-year-old male came with recurrent abscess in the lower abdominal wall and underwent incision and drainage three times earlier. Scar on lower abdomen and active sinuses on right and left ischiorectal fossa were noted. Internal opening was felt at anal mucosa posteriorly. Transrectal ultrasonography revealed posterior anal fistula, extending to left gluteum and traced till left ramus. Seton was placed in the tract from 5’o clock position to internal opening at 6’o clock position. Every week Ksharasutra changed for 8 weeks. This healed internal opening, right and left ischiorectal sinuses. Left tract toward groin and lower abdomen wall showed fibrosis. Same was confirmed through review scan. Six years of follow-up has shown no signs of recurrence.
