Current trends in the diagnosis and management of post-herniorraphy chronic groin pain.

Inguinodynia (chronic groin pain) is one of the recognised complications of the commonly performed Lichtenstein mesh inguinal hernia repair. This has major impact on quality of life in a significant proportion of patients. The pain is classified as neuropathic and non-neuropathic related to nerve damage and to the mesh, respectively. Correct diagnosis of this problem is relatively difficult. A thorough history and clinical examination are essential, as is a good knowledge of the groin nerve distribution. In spite of the common nature of the problem, the literature evidence is limited. In this paper we discuss the diagnostic tools and treatment options, both non-surgical and surgical. In addition, we discuss the criteria for surgical intervention and its optimal timing.
