Integrative management of high transsphincteric fistula-in-ano with a rectal opening: A case report

Abstract

Abstract Transsphincteric fistula is a type of complex anal fistula, often considered a refractory surgical condition, which has the potential to produce complications, such as recurrent infections, abscess formation, and incontinence. A 48-year-old male farmer was diagnosed with a high transsphincteric fistula abscess with a secondary rectal opening based on clinical examination and magnetic resonance imaging findings. Under saddle block, incision and drainage of fistula abscess was performed, followed by threading of Apamarga Kshara Sutra (medicated seton) between the abscess cavity and the primary internal opening at 6 o’clock on the dentate line. Another internal opening was also identified in the lower rectum, left as it is. Panchavalkala Kwatha for sitz bath once a day, Varunadi Kwatha 20 mL twice a day orally, Kachanar Guggulu (500 mg) two tablets three times a day, and Apamarga Kshara Tail (AKT) dressing was prescribed for 124 days to facilitate optimal healing and management. Prophylactic as well as therapeutic antibiotics and analgesics were administered for 7 days. The fistula took 103 days for complete healing with a unit healing time of 0.251 day/cm3. Medicated seton on the dentate line facilitated drainage of the infected gland and healed the secondary rectal opening. Ischiorectal abscess cavity healed by secondary intention. This case report demonstrates that a high transsphincteric fistula-in-ano with a rectal opening can be successfully managed without fistulotomy to treat the secondary rectal opening. Chemical debridement of the infected anal gland was achieved by a medicated seton, and a new seton was replaced every 7 days until the cutting and healing of the fistula track. It also facilitated the drainage of the exudate. Wound management by AKT and adjuvant medicament supported faster recovery.
