Abstract:

Anorectal abscess is a common acute infectious disease in department of colorectal surgery. It is easy to spread to deep perianal spaces. Surgical incision and drainage are the main therapeutic principle. There are many surgical approaches and the classic approaches include external approach of external sphincter, intersphincteric approach and intrarectal approach. The irregular approach increases the formation of anal fistula or complex anal fistula and increases the risk of fecal incontinence. In this paper, the different operative approach of abscess is described, which can provide basis for standardized treatment, decrease the formation of anal fistula or complex anal fistula, reduce patients' complication, improve quality of life and save medical resources.
