Onlay parastomal hernia repair with cross-linked porcine dermal collagen biologic mesh: long-term results

Purpose The optimal technique and mesh type for parastomal hernia repair have yet to be ascertained. Biologic meshes have been advocated in parastomal hernia repair due to purported resistance to infection in contaminated fields. The aim of this study was to evaluate the effectiveness of additionally cross-linked acellular porcine dermal collagen mesh (Permacol™) for onlay parastomal hernia repair.
