ABSTRACT: Mesh reduces recurrence after adult umbilical hernia repair, but the benefit is less certain for the smallest defects. This narrative review examines the choice of repair, with particular attention to preperitoneal mesh and minimally invasive extraperitoneal techniques. Defect width is classified according to the EHS/AHS framework as small (0 - 1 cm), medium (>1 - 4 cm), or large (>4 cm) [1]. Randomized trials support mesh over suture repair for defects measuring 1 - 4 cm. For hernias
