Medialization after combined anterior and posterior component separation in giant incisional hernia surgery, an anatomical study.

Background: To obtain tension-free closure for giant incisional hernia repair, anterior or posterior component separation is often performed. In patients with an extreme diameter hernia, anterior component separation and posterior component separation may be combined. The aim of this study was to assess the additional medialization after simultaneous anterior component separation and posterior component separation.

Hernia width explains differences in outcomes between primary and incisional hernias: a prospective cohort study of 9159 patients.

Purpose: Data on primary (PH) and incisional hernias (IH) are often pooled, even though several studies have illustrated that these are different entities with worse outcomes for IHs. The aim of this study is to validate previous research comparing PHs and IHs and to examine whether hernia width is an important contributor to the differences between these hernia types.

Methods: A registry-based, prospective cohort study was performed, utilizing the French Hernia Club database.
