Roos M, et al. - Inguinal hernia recurrence rates 5 years after endoscopic totally extraperitoneal (TEP) inguinal hernia repair were determined when lightweight vs heavyweight mesh was used. Researchers randomized 950 male adult patients with primary unilateral hernias to TEP hernia repair with heavyweight (Prolene) or lightweight (Ultrapro) mesh from 2010 to 2012. Outcomes suggest a low overall recurrence rate 5 years after TEP repair. Compared to heavyweight meshes, Ultrapro lightweight meshes showed higher recurrence rates and thus are not recommended for endoscopic TEP inguinal hernia repair.
