27. <strong>The</strong> Role <strong>of</strong> Bioactive Prosthetic Material…<br />

367<br />

Technology <strong>International</strong> XV in July 2006 [ 9 ]. Since then, there have<br />

been many more reports using BPM, acellular dermal matrices, and<br />

other biologic materials for hernia repair. <strong>The</strong> aim <strong>of</strong> this chapter is to<br />

review the topic <strong>of</strong> BPMs and their application to inguinal hernia and<br />

sports hernia repairs.<br />

Basic Differences in Bioactive Prosthetic Materials<br />

Table 27.1 summarizes the BPMs currently on the market in the<br />

United States. <strong>The</strong>y differ based on their mammalian source (animal or<br />

human), tissue <strong>of</strong> origin (dermal, pericardial, bladder, or intestinal submucosa),<br />

as well as their methods <strong>of</strong> processing (cross-linked or not<br />

cross-linked) and sterilization. All <strong>of</strong> these differences may lead to differences<br />

in the healing process and thus clinical outcome. With the<br />

exception <strong>of</strong> AlloDerm ® , Surgisis<br />

®<br />

, and Strattice TM , peer- reviewed studies<br />

outlining the clinical outcome from implantation <strong>of</strong> biologic tissue is<br />

significantly lacking.<br />

Mammalian source may be considered when choosing among the<br />

various BPMs available. Human cadaveric tissues <strong>of</strong>fer the advantage <strong>of</strong><br />

using allograft (within species) sourcing and thus lacking interspecies<br />

rejection risk. <strong>The</strong> source <strong>of</strong> such tissues is donor dependent, with variability<br />

in composition, health, thickness, and age <strong>of</strong> the tissue.<br />

Additionally, there is risk <strong>of</strong> disease transmission within species; indeed,<br />

there have been reports <strong>of</strong> disease transmission in human cadaveric<br />

allograft products <strong>of</strong> the dura mater in Japan from the 1990s [ 10 ].<br />

Alternatively, animals can be raised to precise specifications to<br />

achieve a more consistent product. <strong>The</strong> risk <strong>of</strong> allergic response to their<br />

ECM is low because <strong>of</strong> the high homology with similar human proteins.<br />

With nonhuman tissues, the risk <strong>of</strong> tissue rejection remains despite<br />

decellularization, as does the rare possibility <strong>of</strong> disease transmission.<br />

<strong>The</strong> specifics <strong>of</strong> each biologic material should be known prior to implantation,<br />

especially when treating certain populations. For example, an<br />

immune-compromised patient may be at higher risk if undergoing<br />

implant with a human cadaveric allograft that is not sterilized. Similarly,<br />

an atopic patient may be at higher risk <strong>of</strong> allergic response to a<br />

xenograft.<br />

BPMs vary in their tissue <strong>of</strong> origin. <strong>The</strong> dermis remains the preferred<br />

tissue source, though products made from alternative tissues, such as the
