Use of an Absorbable Mesh to Repair Contaminated Abdominal-Wall Defects

摘要: • When polypropylene mesh (Marlex) is used to repair contaminated abdominal-wall hernias, a high incidence of mesh-related chronic infection, drainage, erosion, and bleeding noted. As an alternative placing in field, the past 18 months we have absorbable polyglycolic acid (Dexon) defects eight patients—three with necrotizing infections, one extensive electrical burn abdominal wall, three infected from previous repair, whose hernia was covered by chronically scar. In seven cases, single sheet sewn fascial margins. four skin closed over mesh; wound packing subsequent grafting were required other four. follow-up studies that ranged months, six patients developed hernias at site placement. None binder. Postoperative development probable are repaired mesh. However, this complication balanced against more serious complications fistula, bleeding, which require removal rigid nonabsorbable meshes 50% 90% cases when latter placed under conditions. Placement for temporary support until contamination resolves enhances likelihood successful placement permanent ( Arch Surg 1986;121:954-960)
