Objective:

To report a rare case of complex anal fistula resulting from a soft tissue infection in the lower limb, emphasizing its significance in surgical practice and literature.

Key Findings:
  • The anal fistula had multiple external openings and extended from the gluteal region to the thigh root, indicating a complex anatomical challenge.
  • Preoperative imaging was crucial for understanding the complex anatomy of the fistula, which may inform future surgical approaches.
  • Postoperative follow-up showed complete healing with no recurrence and preserved anal sphincter function, underscoring the success of the intervention.
Interpretation:

This case illustrates the importance of multimodal imaging in planning surgery for complex anal fistulas, suggesting that such approaches may enhance surgical outcomes in similar cases.

Limitations:
  • The case is a single instance and may not be generalizable to all complex anal fistula cases, highlighting the need for further studies.
  • Long-term follow-up data beyond six months is not provided, which may limit the understanding of recurrence rates.
Conclusion:

The successful management of this complex anal fistula emphasizes the role of advanced imaging and combined surgical techniques in preserving sphincter function, suggesting a model for future cases.
