Establishing Peer Consensus About the Use of Long-Term Biosynthetic Absorbable Mesh for Hernia (Grades 2-3) as the Standard of Care.

ABSTRACT

BACKGROUND: Standard synthetic and biologic meshes, often used in hernia repair, have commonly been used and each have their strengths but associated drawbacks. Long-term biosynthetic absorbable (LTBA) mesh has been developed to combine the strengths of synthetic and biologic meshes without the associated weaknesses. As a newer type of mesh, the supporting evidence base is still growing, and their optimum use has yet to be defined. This consensus was initiated to provide insight into those situations where a LTBA might be considered the Standard of Care in ventral hernia repair grades 2-3 (original classification, 2010) of the Ventral Hernia Working Group. METHODS: A steering group of expert surgeons identified 35 statements, based around the evidence supporting LTBA, surgical technique, patients type most suitable for LTBA, risk-benefit of LTBA, patient and surgeon considerations, LTBA value. Surgeons involved in hernia repair received an online survey to assess consensus with these statements. Consensus was defined as high if ≥ 70% and very high if ≥ 90% of respondents agreed. Statements that had not achieved consensus agreement were revised and these were then issued for a subsequent round. Finally, 34 statements were included. RESULTS: Two hundred fifty-five surgeons were involved. Fourteen statements (41%) achieved very high consensus, 24 achieved consensuses (≥ 70-< 90%), whilst one (3%) just failed to achieve consensus with an agreement score of 69%. CONCLUSIONS: Expert consensus opinion about the use of LTBA for hernia (Grades 2-3) as the Standard of Care was achieved. Based on the consensus scores, the steering group derived eleven keys.
