The paper reports the author’s experience of the use intraperitoneal of Gore-Tex Dual Mesh Biomaterial in large incisional hernia operations in patients over seventy. From January 1999 to December 1999 we operated on 24 patients for treatment of abdominal wall defect. In all patients we used a Dual Mesh Plus Biomaterial. Overall mortality was 0. Morbility was 9,5%. Follow-up is too short for definitive considerations about the incidence of recurrences but our initial experience with this material encourages us to use it again for replacement of abdominal wall defects in the age.
