Abstract
INTRODUCTION: Anterior component separation (ACS) is a well-established, highly functional technique to achieve fascial closure in complex abdominal wall reconstruction (AWR). Unfortunately, ACS is also associated with an increased risk of wound complications. Perforator sparing ACS (PS-ACS) has more recently been introduced to maintain the subcutaneous perforators derived from the deep epigastric vessels. The aim of this study is to evaluate wound-related outcomes in patients undergoing open AWR after implementation of a PS-ACS technique. METHODS: A prospectively collected database were queried for patients who underwent open AWR and an ACS from 2006 to 2018. Patients who underwent PS-ACS were compared to patients undergoing ACS using standard statistical methods. Patients undergoing concomitant panniculectomy were included in the standard ACS group. RESULTS: In total, 252 patients underwent ACS, with 24 (9.5%) undergoing PS-ACS. Age and specific comorbidities were similar between groups (all p > 0.05) except for the PS-ACS groups having a higher rate of prior tobacco use (45.8% vs 19.6%, p = 0.003). Mean hernia defect area was 381.6 ± 267.0 cm2 with 64.3% recurrent hernias, and both were similar between groups (all p > 0.05). The PS-ACS group did have more complex wounds with more Ventral Hernia Working Group Grade 3 and 4 hernias (p = 0.04). OR time and length of stay were similar between groups (all p > 0.05). Despite increased complexity, wound complication rates were much lower in the PS-ACS group (20.8% vs 46.1%, p = 0.02), and all specific wound complications were lower but not statistically different. Hernia recurrence rate was similar between PS-ACS and ACS groups (4.2% vs 7.0%, p > 0.99) with mean follow-up of 27.7 ± 26.9 months. CONCLUSIONS: In complex AWR, preservation of the deep epigastric perforating vessels during ACS significantly lowers the rates of wound complications, despite its performance in more complex patients with an increased risk of infection. PS-ACS should be performed preferentially over a standard ACS whenever possible.
