In hernia repairs, the posterior components separation (PCS) technique plays a key role, but its precise impact on the abdominal wall remains unclear. Researchers at the Cleveland Clinic investigated this. They discovered that retrorectus dissection significantly reduced tension on the anterior fascia, ideal for cases requiring anterior fascial advancement. Meanwhile, incision of the posterior lamella of the internal oblique and transversus abdominis muscle release (TAR) lowered tension on the posterior fascia, making them beneficial for posterior fascial advancement. This quantitative insight aids surgeons in making informed intraoperative decisions during PCS.
