Advancements in Fully Absorbable Mesh for Hernia Repair Key Insights from WALS 2025

Introduction Hernia repair remains one of the most common surgical procedures worldwide, with over 1.6 million surgeries performed annually in the United States alone. Traditional non-absorbable synthetic meshes, such as polypropylene, have long been the standard for reinforcing weakened tissue and reducing recurrence rates. However, complications like chronic pain, mesh migration, and infection have driven innovation toward fully absorbable meshes. At the 8th World Congress of Laparoscopic Surgeons (WALS) 2025, held in March 2025, leading surgeons and researchers presented groundbreaking advancements in fully absorbable mesh technologies, offering new hope for improved patient outcomes. This article synthesizes key insights from the congress, focusing on the clinical applications, benefits, and future directions of these innovative materials. The Evolution of Fully Absorbable Mesh Fully absorbable meshes, designed to degrade naturally in the body while promoting tissue regeneration, represent a significant leap forward in hernia repair. Unlike permanent meshes, which remain indefinitely and can cause long-term complications, absorbable meshes dissolve over time, leaving behind strengthened native tissue. At WALS 2025, Dr. Neeraj Goel highlighted the development of bioabsorbable materials like poly-4-hydroxybutyrate (P4HB) and advanced synthetic polymers, which offer a balance of strength and controlled degradation. These meshes act as temporary scaffolds, supporting tissue repair until the body’s natural collagen and scar tissue provide sufficient reinforcement. Key Materials Showcased P4HB-Based Meshes (e.g., Phasix™): P4HB meshes, such as the Phasix™ ST umbilical hernia patch, recently cleared by the FDA in April 2025, were a focal point at WALS. These meshes degrade over 12–18 months, transforming into water and carbon dioxide, minimizing foreign body reactions. Clinical data presented showed no recurrences and reduced chronic pain in laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repairs after 30 months of follow-up. Synthetic Absorbable Polymers (e.g., Vicryl®, Bio-A®): These meshes, discussed by Dr. Bernabé Quesada, degrade faster (2–36 months) and are particularly effective in contaminated surgical fields, where infection risks are high. Their use in paraesophageal hernia (PEH) repairs demonstrated low morbidity and high patient satisfaction, despite a 29.4% radiological recurrence rate in large hiatal hernias. Biological Absorbable Meshes (e.g., Surgisis®, AlloDerm®): Derived from porcine or bovine tissues, these meshes integrate well with human tissue but are costlier. WALS presentations noted their preference in high-risk cases, such as strangulated hernias, due to their resistance to infection, though long-term efficacy remains under evaluation. Clinical Outcomes and Benefits The WALS 2025 presentations underscored several advantages of fully absorbable meshes, supported by emerging clinical evidence: Reduced Complications: Unlike non-absorbable meshes, which can cause erosion, fibrosis, or esophageal stenosis in hiatal hernia repairs, absorbable meshes showed no major mesh-related complications in studies of large hiatal hernias. For example, a series of 65 patients with laparoscopic hiatal hernia repairs reported a 76.5% satisfaction rate with no significant adverse events. Lower Chronic Pain: P4HB meshes in inguinal hernia repairs resulted in less chronic pain and discomfort compared to synthetic non-absorbable meshes, improving patients’ quality of life. Infection Resistance: Absorbable meshes, particularly biological ones, are ideal for contaminated or infected surgical fields, as they degrade without requiring removal, unlike permanent meshes that may necessitate complex explantation surgeries. Conclusion The advancements in fully absorbable mesh for hernia repair presented at WALS 2025 mark a transformative moment in surgical care. These meshes offer a safer, more biocompatible alternative to traditional permanent meshes, with reduced complications and improved patient comfort. While challenges like cost and long-term efficacy remain, the integration of absorbable meshes with cutting-edge laparoscopic and robotic techniques is paving the way for better outcomes. As research progresses and more data emerges, fully absorbable meshes are poised to redefine the standard of care in hernia repair, aligning with the broader trend toward personalized, minimally invasive surgery. https://www.laparoscopyhospital.com/S...
