Abstract:
Fistula-in-ano is a common anorectal disease that significantly affects patients' physical health due to pain and itching, and may lead to psychological disorders such as anxiety and depression. Complex fistula-in-ano, a more severe and challenging type of this disease, has attracted widespread attention in the medical field. Transanal opening of intersphincteric space(TROPIS), as an innovative surgical treatment, involves the excision of the fistula tract through the intersphincteric approach and the repair of the internal anal sphincter defect, showing a high success rate. Moreover, TROPIS has demonstrated good curative effects and a low incidence of postoperative complications in both short-term and long-term outcomes. Despite this, TROPIS has certain limitations and controversies, including the uncertain wound healing time after surgery. This article reviews the development, technical points, indications, contraindications, and efficacy and safety of TROPIS for the treatment of fistula-in-ano, and compares it with other surgical techniques, hoping to provide a reference for clinical physicians in the treatment of complex fistula-in-ano.
