Summary

Autologous PRP currently has many uses in surgical and medical therapy. Compared with other regenerative therapies, PRP is easy-to-prepare, low-cost, and does not require complex equipment. The use of autologous PRP avoids immunological side effects. Data is lacking on the use of PRP in the treatment of anal fissure. This study evaluated PRP as an alternative medical treatment for chronic anal fissures.

Detailed description

. Chronic anal fissures are mucosal ulcers in the anal canal distal to the dentate line and most often present with severe pain and bleeding during defecation. The symptoms of chronic anal fissures persist for more than 8 weeks and do not respond well to medical treatment. This randomized controlled trial investigated the effects of PRP on the healing of chronic anal fissures, which can be considered as nonhealing ulcers. High anal sphincter pressure can cause chronic anal fissures by producing mucosal ischemia in the posterior anal canal that delays wound healing, ultimately resulting in a chronic nonhealing ulcer. Increased anal sphincter pressure induces constipation and spasms in the arterioles that form the mucosal blood supply.9 Botulinum toxin, calcium channel blockers, nitrates, or surgery promote healing by reducing anal sphincter pressure, and increasing blood flow. Autologous PRP has been shown to speed recovery and improve pain and quality of life scores of patients treated for chronic wounds.PRP reduced complaints and accelerated epithelialization and healing in patients with chronic anal fissures. PRP, which can be obtained easily and did not have any harmful patient effects may be an alternative to surgery in patients with chronic anal fissures. The duration of symptoms should be considered during the evaluation of treatment options.

DRUG	Anrecta	self-administered topical glyceryl trinitrate (anrecta), in the perianal area twice a day
BEHAVIORAL	sitz bath	participants were told to take a hot water sitz bath once a day
DIETARY_SUPPLEMENT	nutrition regulation	The study participants were told to eat a fiber-rich diet and to drink least 2 liters of water daily
