Background
Posterior component separation with transversus abdominis release technique is increasingly being used for abdominal wall reconstruction in complex abdominal wall repair. The main purpose of this study is to present a modification of the surgical technique originally described that facilitates the surgical procedure and offers additional advantages.
Methods
Based on the knowledge of the anatomy of the retromuscular space and the preperitoneal aerolar tissue distribution, we start the incision on the posterior rectus sheath from the arcuate line in a down to up direction. The posterior rectus sheath is incised 0,5–1 cm medial to the linea semilunaris and cut longitudinally as far as the fibers of transversus abdominis muscle that are divided in the superior part of the abdomen. It is also possible to avoid cutting the fibers of this muscle if we incise the posterior rectus sheath in an oblique direction to the midline from the umbilical area. Since 2012 to 2016, 69 consecutive patients with down to up TAR have been prospectively followed. Main outcome measures included demographics, perioperative details, wound complications, and recurrences.
Results
Between 2012 and 2016, we have operated 69 patients with down to up TAR technique. Mean operative time was 251 (range 65–566) minutes. Mean hospital stay was 9,8 (2–98) days. 10 patients presented surgical site events (14,5%): 6 patients had superficial site infection, 3 deep and 1 organ space. During follow-up, 3 patients (4,3%) presented incisional hernia recurrence.
Conclusions
This novel modification allows a simpler dissection of the preperitoneal retromuscular space and makes the TAR technique easier to perform. It also enables to incise only the insertion of the transversalis fascia cranially.
