Introduction: Component separation techniques for the treatment of complex abdominal wall defects have gained world acceptance. Transversus abdominis release (TAR) has shown to improve clinical outcomes, but this technique could develop devasting complications when it is used in suboptimal conditions. We aimed to evaluate postoperative outcomes and long-term follow up after TAR for incisional hernia repair.
Methods: A consecutive series of patients undergoing TAR for complex incisional hernias between 2014 and 2019 with a minimum of 6-months follow up were evaluated. Demographics, operative variables, 30-day postoperative outcomes and long-term follow up with focus in recurrence rate were analyzed. Postoperative imaging which involves abdominal wall status was also evaluated to find recurrences without clinical appearance.
Results: A total of 50 TAR repairs were included. Thirty patients were men (60%), mean age was 65 (35-83) years and BMI was 28.5 +/- 3.4 kg/m2. Preoperative CT-scan revealed a mean Tanaka index of 24.2 +/- 6.3 %. Defect area was: 420 (100-720) cm2and mesh area was: 900 (500-1050) cm2. There were 80 % clean procedures and in 60% of the patients a lipectomy was associated. Average operative time was: 252 (162-438) min. Average hospital stay was 4.5 days (2 – 16). Thirty-day morbidity was: 24% (12 patients); 8 SSIs (2 deep, 6 superficial), 3 SSO (seromas) and 1 (2%) reoperation with mesh extraction. Postoperative imaging (CT-scan) was performed in 70% of patients (all had oncological history). Overall recurrence rate was 4% (2 patients) after 28.2 (6-79) months of follow up. No mortality was registered.
Conclusion: In our cohort TAR was shown to have acceptable postoperative morbidity for the treatment of large incisional hernias. Long-term follow-up showed low recurrence rate, even when it was challenged by CT-scan in the majority of the cases.
