Abstract
Complex anal fistula remains a therapeutic challenge in anorectal surgery, with the core challenge lying in balancing complete eradication of the fistula with preservation of anal sphincter function. Intersphincteric approaches, grounded in the intersphincteric infection theory, enable minimally invasive treatment of complex anal fistula through precise anatomical dissection, and have become a hot topic in clinical practice and research worldwide. This review focuses on the theoretical origins and anatomical basis of intersphincteric approaches, as well as their application and development in the treatment of complex anal fistula. It comprehensively elaborates on the anatomical foundations and technical evolution of this series of procedures, systematically analyzes the technical features and clinical outcomes of Parks procedure and modified Parks seton procedure, ligation of the intersphincteric fistula tract (LIFT), transanal opening of intersphincteric space (TROPIS), and various modified techniques, and discusses future directions in this field, aiming to provide a comprehensive theoretical and practical reference for the clinical management of complex anal fistula.
