Reconstruction of infected abdominal wall defects using latissimus dorsi free flap

Abstract

Introduction Infected abdominal defects are a challenge to surgeons. In this study, we describe 10 cases in which the latissimus dorsi myocutaneous flap was used for successful reconstruction of abdominal wall defects severely infected with methicillin-resistant Staphylococcus aureus (MRSA).

Methods Retrospective review of 10 patients with abdominal wall defects that were reconstructed using the latissimus dorsi myocutaneous flap between 2002 and 2010. All patients had abdominal defects with hernias, combined with MRSA infections. The sizes of the flaps ranged from 120 to 364 cm2. The deep inferior epigastric artery was the recipient vessel in nine patients and the internal mammary vessels were used for one patient.

Results There were no complications relating to the flaps, although there were other minor complications including wound dehiscence, haematoma and fluid correction. After reconstruction, there were no signs of infection during follow-up periods, and the patients were satisfied with the final results.

Conclusion Reconstruction using the latissimus dorsi myocutaneous flap, including muscle fascia structures, is a potential treatment option for severely infected large abdominal wall defects.
