Abstract

Background: The hybrid approach to abdominal wall reconstruction (AWR) for abdominal wall hernias combines minimally invasive posterior component separation and retromuscular dissection with open fascial closure and mesh implantation. This combination may enhance patient outcomes and recovery compared to the open approach alone. The purpose of this study is to evaluate the operative outcomes of hybrid vs. open abdominal wall reconstruction. Methods: A retrospective review was conducted to compare patients who underwent open versus hybrid AWR between September 2015 and August of 2018 at Anne Arundel Medical Center. Patient demographics and perioperative data were collected and analyzed using univariate analysis. Results: Sixty-five patients were included in the final analysis: 10 in the hybrid and 55 in the open groups. Mean age was higher in the hybrid vs. open group (65.1 vs. 56.2 years, p < 0.05). The hybrid and open groups were statistically similar (p > 0.05) in gender distribution, mean BMI, and ASA score. Intraoperative comparison found hybrid patients parallel to open patients (p > 0.05) in mean operative time (294.5 vs. 267.5 min), defect size (14.4 vs. 13.6 cm), mesh area, and drain placement. The mean total hospital cost was lower in the hybrid group compared to the open group ($16,426 vs. $19,054, p = 0.43). The hybrid group had a shorter length of stay (5.3 vs. 3.6 days, p = 0.03) after surgery and was followed for a similar length of time (12.3 vs. 12.6 months, p = 0.91). The hybrid group showed a lower trend of seroma, hematoma, wound infection, ileus, and readmission rates after surgery. Conclusion: A review of patient outcomes after hybrid AWR highlights a trend towards shorter length of stay, lower hospital cost, and fewer complications without significant addition to operative time. Long-term studies on a larger number of patients are definitively needed to characterize the comprehensive benefits of this approach.
