Laparosocpic "Intraperitoneal Underlay Mesh"-Plus: A Viable Approach for Incisional-Ventral Hernia Repair.

Area of Science:

• Hernia Surgery
• Surgical Innovation
• Abdominal Wall Reconstruction

Background:

• Early Intraperitoneal Underlay Mesh (IPUM) techniques faced challenges like high recurrence rates and poor functional outcomes due to design flaws and lack of defect closure.
• These limitations led to skepticism about intraperitoneal mesh placement and a preference for retrorectus techniques.
• Complications, though rare, were linked to mesh design and fixation issues.

Purpose of the Study:

• To evaluate the evolution and efficacy of Intraperitoneal Underlay Mesh (IPUM) techniques in ventral hernia repair.
• To assess the impact of combining mesh placement with primary defect closure (IPUM+) on surgical outcomes.
• To compare IPUM+ with alternative hernia repair methods.

Main Methods:

• Review of long-term studies, meta-analyses, and randomized trials on IPUM and IPUM+ techniques.
• Analysis of outcomes including recurrence rates, mesh bulging, seroma formation, and abdominal wall function.
• Comparison of complication profiles associated with different mesh types and fixation methods.

Main Results:

• The evolution to IPUM+ (primary defect closure with advanced composite meshes) since 2007 has led to significantly improved functional results and reduced complications.
• IPUM+ has demonstrated broader acceptance among surgeons and patients due to its enhanced reliability and effectiveness.
• Studies indicate IPUM+ is a valuable technique for small to moderate or recurrent ventral hernias, especially when compared to alternative methods with ongoing long-term follow-up.

Conclusions:

• Intraperitoneal Underlay Mesh (IPUM) techniques have evolved successfully with the incorporation of primary defect closure (IPUM+), addressing previous limitations.
• IPUM+ is a reliable and effective option for specific ventral hernia repairs, offering better functional outcomes and fewer complications.
• Future research should focus on defining the role of IPUM+ in personalized hernia care, including hybrid approaches and new technologies for complex cases.
