ABSTRACT

Anal fistula is a common disease, surgical treatment is the best option. There are many kinds of surgical treatments for anal fistula, traditional surgical methods, such as fistulotomy and fistulectomy are more thorough in treating internal opening, infection and fistula tract, but the injury to the sphincter is also greater. In recent years, surgery is becoming refined, many scholars pay more and more attention to the protection of anal sphincter, which has derived a series of minimally invasive surgeries, such as Endorectal advancement flap procedure, Ligation of intersphincteric fistula tract, Fistula laser closure procedure, Video-assisted anal fistula treatment, Over-the-scope clip, Endofistular polyurethane-sponge vacuum therapy and biological sphincter preservating procedures. This paper describes the application status and progress of sphincter preserving surgeries by reviewing relevant literature, in order to provide relevant reference for clinical workers, optimize the treatment plan and improve the cure rate.
