Biocellulose for Incisional Hernia Repair-An Experimental Pilot Study.

Ventral or incisional hernia are a common disease pattern in general surgery. Mostcommonly, a mesh repair is used for reconstruction, whereby the mesh itself might causecomplications, like infections or adhesions. Biological materials, like biocellulose, might reducethese clinical problems substantially. In this prospective rodent study, a biocellulose mesh(produced by Gluconacetobacter xylinus) was implanted either by a sublay technique or assupplementation of the abdominal wall. After an observation period of 90 days, animals weresacrificed. The adhesions after the reconstruction of the abdominal wall were moderate. Thehistologic investigations revealed that the biocellulose itself was inert, with a minimal regenerativeresponse surrounding the mesh. The explanted mesh showed a minimal shrinkage (around 15%) aswell as a minimal loss of tear-out force, which might be without clinical relevance. This is the firstin vivo study describing biocellulose as a suitable mesh for the repair of ventral hernia in twodifferent hernia models. The material seems to be a promising option for solving actual problems inmodern hernia surgery.
