Open preperitoneal vs. endoscopic repair for bilateral groin hernias: a registry-based two-arm comparison

Evidence comparing open preperitoneal and laparo-endoscopic approaches for bilateral groin hernia repair remains limited. This study aimed to compare perioperative and long-term outcomes of open preperitoneal techniques (OPPs) [transinguinal preperitoneal (TIPP), minimal open preperitoneal (MOPP), and the Ugahary techniques] vs. endoscopic repair (Endo) [transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) techniques] for bilateral primary groin hernias using the French registry.
