Abstract
Extracellular matrix is used in various applications We present our preliminary experience using a new device that consists of a porcine extracellular matrix with an epithelial basement membrane MatriStem® ACell Inc Columbia MD USA for adolescent pilonidal diseaseA retrospective review of four patients with pilonidal disease was undertaken Three occurred in the gluteal cleft and the fourth in the umbilicus In the first patient the wound deficit was filled with lyophilized MicroMatrix powder and a sheet of Multilayer Wound Matrix was placed to cover the wound In the second patient two sinus tracts were debrided packed with MicroMatrix and a sheet of fenestrated Burn Matrix was applied In the third patient MicroMatrix and Surgical Matrix PSMX sixlayer was applied as a roll filling the dead space In the last patient an umbilical sinus 3 cm deep was packed with MicroMatrix powder followed by a rolled sheet of 2ply Surgical Matrix RS Patients were evaluated weekly postoperatively and more MicroMatrix and sheet material was added if a wound deficit was still present Measurements were taken in two dimensions diameter and depth to characterize woundsResolution of wound deficit was graphed versus time Pain was assessed by scoring 0–10 Rapid wound closure was achieved Two of the patients had failed wound healing with saline dressing changes prior to MatriStem application These two patients in particular were highly satisfied with the comfort of the MatriStem approach relative to their time with saline dressings Most had no pain after 1 week when bolster sutures were removedIn the treatment of open pilonidal wounds in adolescents porcine urinary bladder matrix wound care devices offer closure times and cost similar to wellestablished methods while offering a substantial advantage in terms of patient comfort and convenience This preliminary experience supports a prospective study
