Transversus abdominis release (TAR) procedure: a retrospective analysis of an abdominal wall reconstruction group

Abstract Complex abdominal wall defects are important conditions with high morbidity, leading to impairment of patients' physical condition and quality of life. In the last decade, the abdominal wall reconstruction paradigm has changed due to the formation of experienced and excellence groups, improving clinical outcomes after surgery. Therefore, our study shows the perspective and outcomes of an abdominal wall reconstruction group (AWRG) in Colombia, focused on the transverse abdominis release (TAR) procedure. A retrospective review of a prospectively collected database was conducted. All the patients older than 18 years old that underwent TAR procedures between January 2014–December 2020 were included. Analysis and description of postoperative outcomes (recurrence, surgical site infection (SSI), seroma, hematoma, and re-intervention) were performed. 47 patients underwent TAR procedure. 62% of patients were male. Mean age was 55 ± 13.4 years. Mean BMI was 27.8 ± 4.5 kg/m2. Abdominal wall defects were classified with EHS ventral Hernia classification having a W3 hernia in 72% of all defects (Mean gap size of 11.49 cm ± 4.03 cm). Mean CeDAR preoperative risk score was 20.5% ± 14.5%. Preoperative use of BOTOX Therapy (OR 1.0 P 0.00 95% CI 0.3–1.1) or pneumoperitoneum (OR 0.7 P 0.04 95% CI 0.3–0.89) are slightly associated with postoperative hematoma. In terms of hernia relapse, we have 12% of cases; all of them over a year after the surgery. TAR procedure for complex abdominal wall defects under specific clinical conditions including emergency scenarios is viable. Specialized and experienced groups show better postoperative outcomes; further studies are needed to confirm our results.
