Late cutaneous fistulae, after a hernioplasty operation for a hernia in the abdominal wall, represent an unusual complication. They can appear a considerable time after a hernioplasty operation and feature the presence of a fistula between the prosthesis and the cutaneous wall. The Authors report the cases of five patients who developed late cutaneous fistulae after an operation for the repair of a hernia of the abdominal wall and the treatment established in the end to correct the existing complication. All five patients were subjected to a second operation to achieve recovery. In fact, conservative medical treatment, before the operation, using antibiotic-therapy for this purpose proved to be ineffective. Only one patient developed hernia recurrence after surgical treatment. Late cutaneous fistulae represent a complication that is difficult to deal with as their treatment has yet to be clearly identified.
