Area of Science:

  • Colorectal Surgery
  • Gastroenterology
  • Surgical Innovation

Background:

  • Cryptogenic complex anal fistulas represent a significant portion (21.1%) of anal fistula cases.
  • Accurate classification and preoperative assessment of anorectal function are crucial for successful treatment.
  • Risk of fecal incontinence necessitates careful surgical planning.

Purpose of the Study:

  • To report personal experience in treating cryptogenic complex anal fistulas over a 10-year period.
  • To evaluate the efficacy and safety of surgical strategies for complex anal fistulas.
  • To emphasize the importance of sphincter preservation in surgical management.

Main Methods:

  • Retrospective analysis of 54 cases of cryptogenic complex anal fistulas treated between 1993 and 2002.

  • Detailed preoperative evaluation including anorectal function assessment.
  • Application of various surgical techniques, with a preference for a mixed fistulectomy-fistulotomy with setons approach.

    • Main Results:

    • A high healing rate of 90.7% (49/54 cases) was achieved.
    • Recurrence or persistence of fistula occurred in 9.3% (5/54 cases).
    • Minor complications were observed in 11.1% (6/54 cases), with no major complications or permanent fecal incontinence.

    Conclusions:

    • A mixed surgical technique (fistulectomy-fistulotomy with setons) is effective for complex anal fistulas, especially when sphincter preservation is a concern.
    • Definitive treatment of complex fistulas can be achieved while minimizing the risk of irreversible anal incontinence.
    • Careful patient selection and surgical strategy are key to successful outcomes in complex anal fistula management.
