摘要

Transversus abdominis release (TAR) is a key technique in complex abdominal wall hernia repair. As extraperitoneal mesh placement with sufficient overlap is feasible in almost every anatomical location, not only large midline defects but also off-midline hernias and those adjacent to osseous abdominal borders can be effectively repaired. Through the introduction of new techniques and instruments (e.g., robotic platforms), TAR can be performed using a minimally invasive approach in many cases. Within this short communication, technical modifications of the original TAR technique, such as posterior rectus sheath release, will be discussed as well.
