“…Such a prosthesis would be (1) chemically inert, (2) noncarcinogenic, (3) resistant to mechanical strain, (4) sterilizable, (5) unmodified by tissue fluids, (6) hypoallergenic, (7) noninflammatory, (8) con¬ formable to different shapes, and (9) nonrigid.9 A host of materials have been tested, including Dacron-reinforced silicon rubber (Silastic),9,10 preserved human dura,10 nylon woven mesh,9 polyester fiber mesh (Mersilene),11 braided carbon fiber," stainless-steel mesh,9 polytetrafluoroethyl¬ ene (Goretex),10,12 and polypropylene mesh (Marlex). 10,12,13 Probably because of its strength and low reactivity, poly¬ propylene mesh has emerged as the prosthetic agent of choice in repairing both clean and contaminated abdominalwall defects.…”
