[Intraperitoneal ventral hernia plasty: the comparison of prosthetic materials]

Area of Science:

• Biomaterials Science
• Surgical Innovation
• Gastrointestinal Surgery

Background:

• Intraperitoneal mesh implants are crucial for abdominal wall repair, particularly in hernia surgery.
• Evaluating the biocompatibility and integration of various prosthetic materials is essential for optimal surgical outcomes.
• Adhesion formation and mesh contraction are significant complications following intraperitoneal implantation.

Purpose of the Study:

• To compare the in vivo performance of different intraperitoneal implant materials in rabbits.
• To assess adhesion formation, retraction, and prosthetic integration of various coated and uncoated meshes.
• To identify the most suitable materials for intraperitoneal mesh hernia plasty.

Main Methods:

• Seventy-six rabbits underwent implantation of polytetrafluoroethylene (PTFE), uncoated polypropylene, and collagen-coated polypropylene meshes.
• Implants were assessed at 14, 90, and 210 days post-implantation.
• Evaluation included assessment of adhesions, mesh retraction, and tissue integration.

Main Results:

• Polytetrafluoroethylene (PTFE) and collagen-coated polypropylene prostheses exhibited the lowest incidence of adhesions.
• Mesh retraction ranged from 5% to 14% across the tested materials.
• Varying degrees of prosthetic integration into the abdominal wall were observed among the different implant types.

Conclusions:

• Polytetrafluoroethylene (PTFE) and collagen-coated polypropylene demonstrate superior biocompatibility for intraperitoneal use.
• These materials show potential for reducing complications like adhesions in hernia repair.
• The findings suggest PTFE and collagen-coated polypropylene are appropriate choices for intraperitoneal mesh hernia plasty.
