Porcine dermal collagen (Permacol) for abdominal wall reconstruction.
OBJECTIVE
A review of Eisenhower Army Medical Center's experience using Permacol (Tissue Science Laboratories, Covington, Georgia) for the repair of abdominal wall defects.


METHODS
Retrospective review of medical records of patients undergoing abdominal wall reconstruction with Permacol.


RESULTS
From July 30, 2003 to February 12, 2005, 9 patients underwent repair of complicated fascial defects with Permacol. Indications for surgery included reoperative incisional hernia repair after removal of a infected mesh (3 patients), reconstruction of a fascial defect after resection of an abdominal wall tumor (2 patients), incisional hernia repair in a patient with a previous abdominal wall infection after a primary incisional hernia repair (1 patient), incisional hernia repair in a patient with an ostomy and an open midline wound (1 patient), emergent repair of incisional hernia with strangulated bowel and multiple intra-abdominal abscesses (1 patient), and excision of infected mesh and drainage of intra-abdominal abscess with synchronous repair of the abdominal wall defect (1 patient). At a median follow-up of 18.2 months, 1 recurrent hernia existed after intentional removal of the Permacol. This patient developed an abdominal wall abscess 7 months after hernia repair secondary to erosion from a suture. Overall, 1 patient developed exposure of the Permacol after a skin dehiscence. The wound was treated with local wound care, and the Permacol was salvaged. Despite the presence of contamination (wound classification II, III, or IV) in 5 of 9 patients (56%), no infectious complications occurred.


CONCLUSIONS
Complex reconstruction of the abdominal wall can be associated with a high complication rate. Placement of a permanent prosthetic mesh in a contaminated field is associated with a high rate of wound infections and subsequent mesh removal. Permacol becomes incorporated by tissue ingrowth and neovascularization. Permacol is a safe and acceptable alternative to prosthetic mesh in the repair of complicated abdominal wall defects.
