Complex anal fistula is a common and refractory anorectal disease in clinical practice. Surgery is currently the main treatment method, and the sphincter-preserving surgical approach is the current surgical trend for complex anal fistula. This article reviews the surgical methods for complex anal fistulas that preserve the sphincter, including transanal opening of intersphincteric space, ligation of the intersphincteric fistula tract, loose-seton technique, endorectal advancement flap, mesenchymal adipose-stem cell transplantation, fistula-tract laser closure, video assisted anal fistula treatment, fibrin glue and anal fistula plug. This article reviews the articles on minimally invasive treatment for anal fistula in PubMed, Cochrane Library CENTRAL and Embase, and introduces the current research progress. The aim is to strive to maintain a balance between curing complex anal fistulas and protecting the function of the sphincter.
