preperitoneal mesh placement
A hernia repair technique involving mesh positioning in the anatomical space between the peritoneum and posterior rectus sheath.
Full Definition
Preperitoneal mesh placement is a cornerstone technique in modern hernia surgery that positions prosthetic mesh in the preperitoneal space to reinforce the abdominal wall from within. This approach provides optimal biomechanical advantage by placing the mesh where intra-abdominal pressure helps maintain its position against the defect. The technique is fundamental to both TEP and TAPP repairs and requires thorough understanding of preperitoneal anatomy to avoid critical structures like the lateral femoral cutaneous nerve.
Usage
Usage note: Distinguish from extraperitoneal (broader term) and intraperitoneal (different approach).
