Onlay mesh versus suture repair for smaller umbilical hernias in adults-early results from SUMMER trial: randomized clinical trial.

Background: Mesh repair is recommended for umbilical hernias larger than 1 cm to reduce recurrence rates, yet current evidence remains limited for smaller umbilical hernias. Important questions concern optimal mesh positioning and wound complications/surgical-site occurrences. The aim of this study was to report the preliminary results of a trial investigating surgical-site occurrences in suture versus mesh repair for umbilical hernias less than or equal to 2 cm.
