Although there is robust literature regarding KP, there is a knowledge gap in the long-term performance of NWP in ventral hernia repair (VHR). We recently reported one-month outcomes of KP versus NWP mesh after VHR; however, long-term outcomes of NWP were not evaluated. This study aims to describe these long-term outcomes.<h4>Methods</h4>Patients who underwent open, clean VHR with Surgimesh WN, a heavyweight NWP mesh, from 2022 to 2025 with one year follow-up were included. Outcomes such as SSO (surgical site occurrence), SSI (surgical site infection), SSOPI (surgical site occurrence requiring procedural intervention), and hernia recurrence were reported at 30Hernia : the journal of hernias and abdominal wall surgery95https://www.ebi.ac.uk/biostudies/studies/S-EPMC12913288biostudies-literature"Long-term outcomes of ventral hernia repair using heavyweight non-woven polypropylene mesh".PMC12913288Beffa LRAKrpata DMMiller BTRisser KMWoo KPPetro CCPrabhu ASRosen MJSchmidt EMfalse"Long-term outcomes of ventral hernia repair using heavyweight non-woven polypropylene mesh".<h4>Purpose</h4>Polypropylene mesh is available in the configurations: knitted polypropylene (KP) and nonwoven polypropylene (NWP).
