Low recto-vaginal fistula cured by Kshar Sutra (a medicated seton) treatment: a case report

Rectovaginal fistulas (RVFs) are challenging to treat, primarily due to their high recurrence rate and the risk of faecal incontinence following surgical intervention. A 30-year-old woman was suffering from low RVF. An herbal medicated seton, known as 'Kshar Sutra,' was used to treat the patient. The local anaesthesia was used in and around the fistula track. Weekly thread changes were done on an outpatient basis for four weeks. There were no complications such as severe bleeding, secondary infection, severe pain, and incontinence. The patient has been fistula-free for the last 5 years. Low RVF can be treated safely by an herbal Kshar Sutra seton without any complications.
