Fissurectomy is a surgical procedure aimed at treating anal fissures, which are painful tears in the mucous membrane of the anus. These fissures can result from various factors, including trauma, constipation, or increased pressure in the anal region. The internal and external anal sphincters are critical muscle structures that control the opening and closing of the anus. The internal sphincter operates involuntarily, meaning it is not consciously controlled, while the external sphincter is under voluntary control. When the internal sphincter experiences excessive resting pressure, it may enter a state of spasm, leading to reduced blood flow to the area. This condition can exacerbate the formation of fissures and hinder the healing process of existing ones. The fissurectomy procedure involves making an incision adjacent to the fissure, allowing for the complete excision of the fissure itself. Additionally, if a sphincterotomy is performed, a lateral incision is made in the internal sphincter to relieve muscle tension without fully severing the muscle ring. This surgical intervention aims to alleviate pain, facilitate the passage of stool, and promote healing of the fissures by reducing the pressure and tension in the anal sphincter muscles.
