Transversus Abdominis Release for Abdominal Wall Reconstruction: Early Experience with a Novel Technique

Abstract

Ventral hernias are common sequelae of abdominal surgery. Recently, transversus abdominis release has emerged as a viable option for large or recurrent ventral hernias. Our objective was to determine the outcomes of posterior component separation via transversus abdominis release for the treatment of abdominal wall hernias in the first series of patients at one institution. We performed a retrospective review of a prospectively maintained database of open ventral hernia repair patients to identify patients who underwent posterior component separation via transversus abdominis release at one institution from 2012 to 2015. Patients who were at least 1 year out from surgery were included. Patient demographic characteristics, operative details, perioperative and postoperative complications, and recurrences were analyzed. Postoperative imaging was reviewed for evidence of morbidity or recurrence. Thirty-seven patients met inclusion criteria; 23 (62.2%) of these patients were female, with a mean age of 57.5 ± 11 years and median BMI of 32.1 kg/m(2) (range 23.6 to 44.0 kg/m(2)). All patients underwent repair with mesh (81.1% polypropylene, 5.4% porcine dermal matrix, and 13.5% biologic/permanent synthetic hybrid). Median defect size was 392 cm(2) (range 250 to 2,700 cm(2)) and median mesh area was 930 cm(2) (range 600 to 3,600 cm(2)). Approximately 24% (9 of 37) of patients experienced a postoperative complication; ileus was the most common (4 patients). Surgical site events requiring intervention (ie drainage and antibiotics) developed in 2 patients. Median follow-up period was 21 months (range 12 to 42 months), during which one recurrence was identified (2.7%). Posterior component separation via transversus abdominis release is a safe and effective method of ventral herniorrhaphy with favorable rates of wound morbidity and recurrence.
