Posterior Component Separation Technique-Original Transversus Abdominis Release (TAR) Technique

The history of ventral hernia repair techniques has seen substantial evolution, from primary suture repair to the introduction of mesh-based procedures, aiming to reduce recurrence rates. Notable advancements include the anterior and posterior component separation techniques. The Transversus Abdominis Release (TAR) technique, a refinement of the posterior approach, emerged to address challenges associated with complex ventral hernias. The TAR technique facilitates midline reconstruction, allowing large mesh placement while minimizing the need for subcutaneous dissection. Despite its benefits, TAR presents potential complications, emphasizing the necessity for meticulous preoperative assessment and training. The paper reviews the historical progression of hernia repairs, details the TAR technique, highlights indications, perioperative care strategies, surgical steps, postoperative management, technical challenges, and emphasizes the critical role of expertise in achieving successful outcomes in complex abdominal wall reconstruction.
