• Purpose The use of component separation results in myofascial release and increased rates of fascial closure in abdominal wall reconstruction(AWR). These complex dissections have been associated with increased rates of wound complications with anterior component separation having the greatest wound morbidity. The aim of this paper was to compare the wound complication rate between perforator sparing anterior component separation(PS-ACST) and transversus abdominus release(TAR). Methods Patients were identified from a prospective, single institution hernia center database who underwent PS-ACST and TAR from 2015 to 2021. The primary outcome was wound complication rate. Standard statistical methods were used, univariate analysis and multivariable logistic regression were performed. Results A total of 172 patients met criteria, 39 had PS-ACST and 133 had TAR performed. The PS-ACST and TAR groups were similar in terms of diabetes (15.4% vs 28.6%, p = 0.097), but the PS-ACST group had a greater percentage of smokers (46.2% vs 14.3%, p < 0.001). The PS-ACST group had a larger hernia defect size (375.2 ± 156.7 vs 234.4 ± 126.9cm 2 , p < 0.001) and more patients who underwent preoperative Botulinum toxin A (BTA) injections (43.6% vs 6.0%, p < 0.001). The overall wound complication rate was not significantly different (23.1% vs 36.1%, p = 0.129) nor was the mesh infection rate (0% vs 1.6%, p = 0.438). Using logistic regression, none of the factors that were significantly different in the univariate analysis were associated with wound complication rate (all p > 0.05). Conclusion PS-ACST and TAR are comparable in terms of wound complication rates. PS-ACST can be used for large hernia defects and promote fascial closure with low overall wound morbidity and perioperative complications.
