Component separation technique (CST) allows the mobilization of large musculofascial flaps of the abdominal wall and was developed for the treatment of very large, primary and incisional abdominal wall hernias. The classic open anterior CST first published by Albanese and later by Ramirez is associated with high complication rates. According to a recent literature review, CST without mesh should no longer be performed because of high recurrence rates. Classic anterior CST is associated with high rates of surgical-site occurrences and infections and should only be performed as endoscopic- and perforator-sparing anterior CST. The unfavorable results of classic CST resulted in the development of numerous new anterior and posterior CST modifications, several of them were minimally invasive. The posterior CST with transversus abdominis muscle (TAM) release (TAR) published by Novitsky et al. is an extension of the original retrorectus Rives operation and Stoppa procedure. The technique avoids vast skin flaps and allows the closure of large abdominal wall defects and insertion of very large retromuscular alloplastic standard sublay meshes without damaging the vessels and intercostal nerves. The TAR procedure is one of the major advances of abdominal wall surgery of the last decades. Several new promising minimally invasive modifications including robotic-assisted TAR have been published recently. The indications and technique of the TAM (TAR) procedure and its minimally invasive modifications are described.
