{ "abstract": "INTRODUCTION:: Long-term independent evidence regarding new mesh types used in inguinal hernia repair is scarce. We previously reported favorable 3-month outcomes for the fixation-free 3-dimensional SWING-Mesh, but early follow-up precluded capturing recurrence or persistent pain.\n\nAIM:: We aimed to assess recurrence, pain, and complications 12 months after fixation-free SWING-Mesh implantation in transabdominal preperitoneal and totally extraperitoneal repairs.\n\nMATERIALS AND METHODS:: A prospective observational cohort study was performed in 19 Polish centers. Consecutive adults undergoing elective laparoendoscopic repair with unfixed SWING-Mesh were enrolled; large direct (M3) defects and emergency procedures were excluded. The unit of analysis was the operated groin. Assessments were performed at discharge, 7–10 days, 30 days, 3 months, and at 12 months following surgery. The primary end point was recurrence; secondary end points were pain (Visual Analog Scale [VAS], 0–10 points) and complications.\n\nRESULTS:: Of 294 cases, 233 (79.3%) were assessed at 12 months; 61 (20.7%) were lost to follow-up. Recurrence was identified in 5 cases (2.15%; 95% CI, 0.7%–4.94%), as compared with none at 3 months. Pain decreased throughout the observation period (Friedman test, P <0.001). In contrast to the 3-month analysis, in which scores at 30 days and 3 months showed no difference, pain scores decreased further between 3 and 12 months (P <0.001), and the number of pain-free cases increased from 78.5% to 93.1%. One case (0.43%) had a VAS score of 4 or higher. Complications remained at 6.9%, with no cases of seroma or hematoma.\n\nCONCLUSIONS:: Fixation-free SWING-Mesh repair demonstrated a 12-month recurrence rate below the prespecified noninferiority margin, very low persistent pain, and complete resolution of structural complications, with pain scores continuing to improve beyond 3 months.", "abstract_shown": true, "affiliations": [ "Śmietański Hernia Center, LUX MED Hospital in Gdansk, Gdańsk, Poland", "Second Department of Radiology, Medical University of Gdansk, Gdańsk, Poland", "Department of General, Vascular, and Oncological Surgery, Mazovian Brodnowski Hospital, Warszawa, Poland", "Department of General and Vascular Surgery, Faculty of Medicine, Medical University of Warsaw, Warszawa, Poland", "Department of General and Minimally-Invasive Surgery, Franciszek Raszeja Municipal Hospital in Poznan, Poznań, Poland", "Department of General and Oncological Surgery, Independent Public Health Care Centre in Brzesko, Brzesko, Poland", "Department of General Surgery, Military Institute of Aviation Medicine, Warszawa, Poland", "Department of General and Oncological Surgery, Florian Ceynowa Specialist Hospital, Gdańsk, Poland", "Department of General and Oncological Surgery, Prof. S.
