A retrospective study on mesh repair alone vs. mesh repair plus pedicle flap for large incisional hernias.

Objective: Our experience with the treatment of large incisional hernias (IH) was reviewed comparing mesh repair alone vs. mesh repair plus pedicle flaps.

Materials And Methods: A retrospective study was performed on patients treated between 2001 and 2005 that underwent component separation technique (CST) repair with polypropylene mesh alone or with polypropylene mesh and local "pedicle" dermal flaps. The primary outcome evaluated was the recurrence rate, secondary outcomes the complication rate, hospital stay and reoperation rate.

Results: Forty-eight patients were reviewed. Six patients (13%) developed an IH recurrence, two of them (4%) required secondary repair. CST combined with prosthetic mesh repair and pedicle flap was performed in 19 patients (39.6%) while CST combined with mesh repair alone in 29 patients (60.4%). The duration of surgery, hospitalization, postoperative complications as well as long-term results were similar.

Conclusions: Dermal pedicled flaps obtained through deepithelization of redundant skin following corrections of large incisional hernias are a safe, relatively easy and effective technique that allows reliable soft tissue coverage of the abdominal submuscular mesh.
