Background: Bhagandar (Fistula in ano) is one among the Ashtamahagad (8 dreadful disorders). Most fistulas are thought to arise as a result of cryptoglandular infection with resultant perianal abscess. It has been a surgical problem because of the high number of postoperative complications such as incontinence of gases and faeces and recurrent course of the disease. Aim: Evaluation of recurrence rate of Bhagandar (Fistula in ano) managed by Udumbar (Ficusglomarata) KsheerSutra. Methods: Participants fulfilling the inclusion criterion will be selected.After the complete healing of the surgical wound and the external opening without any sign of recurrence the observation will start. The postoperative site will be assessed at 30th, 90th, 180th, 365th day (1, 3, 6 and 12 months) after the healing of the fistula. Failure was defined as a clinical diagnosis of fistula recurrence at any time in the postoperative follow-up defined by clinical interview and physical examination for perianal abscess or boil, pus discharge, tenderness and in durations. Faecal continence and patient satisfaction will be recorded at each follow-up visit and adverse events will be monitored. Results: Results will be drawn from the observations of objective parameters. Conclusion: This will be drawn based on statistical analysis of the collected data.
