After giving replacement breasts made from pigskin to six women in Germany, doctors in Munich detailed the new method today, saying it results in fewer scars for masectomy patients, according to dpa. Senior doctor Darius Dian said the procedure used a "dermal matrix" made from an underlayer of the skin of pigs. The pig"s own cells are removed from the skin. The woman"s own cells and blood vessels repopulate the material after it has been transplanted. A US biotechnology manufacturer won regulatory approval a year ago in the European Union to market the product, known as Strattice. The current standard method to reconstruct the breast relies on transplanting flaps of the patient"s own skin from the belly, back or buttocks, but this leaves scars there and may also lead to capsular contracture, a tightening of skin at the new join. Munich University"s Gynaecology Clinic said it was the first clinic in Europe to offer the procedure. No major study of it has been completed yet, but one is under way in the United States, Dian said.
