Transversus abdominis release (TAR) is a relatively recent surgical technique for ventral hernia repair which allows placement of a large prosthesis in the retro-muscular plane with considerable myofascial medialization. A retrospective review of 100 cases who underwent TAR for complex ventral hernias was performed to evaluate the safety and efficacy of TAR in a series of large ventral hernias.


Between March 2016 and May 2019, 100 consecutive patients who underwent open TAR were identified from our prospectively maintained database. A retrospective review was performed to analyze patient demographics, peri-operative events, adverse outcomes and recurrence.


12 primary and 88 incisional hernia cases underwent TAR with prosthetic mesh repair during the study period. Mean age was 52.5 years, mean BMI was 30.87 kgs/m2, mean ASA class 1.95. In our series, 41% were diabetic, 11% had COPD. All patients underwent preoperative CT scans. The mean defect was 140.18 cm2. Average mesh area was 1344 cm2. Average blood loss was 245 mL. Defects were bridged in 19% cases despite bilateral component separation. Readmission rate at 1 month was 3%, for wound complications. We recorded 9 surgical site infections, 17 surgical site occurrences, 10 of which needed procedural interventions. We recorded no recurrences at a mean follow-up duration of 20.2 months.


Our early results with TAR are encouraging. We have demonstrated that the repair allows anatomical reconstruction with a large sublay mesh while inflicting minimal morbidity. TAR can be a valuable tool in complex ventral hernia repair.
