Abstract

Background:

Incisional hernias with history of recurrence or infection remain a challenge, with high postoperative morbidity and recurrence rates. The purpose of this study is to evaluate outcomes of patients treated with human cadaveric acellular dermis as an adjunct to abdominal wall reconstruction.

Methods:

We retrospectively reviewed 39 abdominal wall reconstructions with human cadaveric acellular dermis performed in 37 patients and compared them with 39 randomly selected cases.

Results:

There is a significant decrease in recurrence rates when human cadaveric acellular dermis is added as an overlay to primary closure plus rectus muscle advancement and imbrication in patients with medium-sized hernias. No differences were observed when adding human cadaveric acellular dermis as an overlay to patients with large-size hernias treated with underlay mesh. The use of human cadaveric acellular dermis did not increase postoperative morbidity rates.

Conclusions:

Improved results with human cadaveric acellular dermis are obtained by achieving tension-free repairs.
