Background: Ventral incisional hernia repair commonly utilizes onlay or retro-rectus sublay mesh placement. Comparative evidence on early postoperative outcomes remains limited in low-resource surgical settings. Objective: This investigation aims to evaluate one-year postoperative outcomes, complication profiles, operative characteristics, and recurrence patterns following open onlay versus retro-rectus sublay mesh repair among patients with ventral incisional hernia. Methods: A quasi-experimental study was conducted from July 2022 to June 2024 at Rajshahi Medical College Hospital, enrolling 60 patients randomized into onlay (n=30) and sublay (n=30) groups. Data on demographics, BMI, defect size, operative duration, postoperative complications, hospital stay, and recurrence were collected. Statistical analyses employed the Student’s unpaired t-test for continuous variables and Chi-square tests for categorical outcomes with significance at p<0.05. Results: Mean age was slightly higher in the sublay group (52.3 ± 7.9 years) than the onlay group (51.1 ± 6.8 years, p=0.42). Normal BMI distribution differed significantly (56.6% vs. 83.3%, p=0.018). Larger defects (>2 cm) were more frequent in sublay repairs (80.0% vs. 66.6%, p=0.21). Operative duration was significantly longer for sublay (132 ± 14 minutes) versus onlay (104 ± 11 minutes, p<0.001). Postoperative seroma (43.3% vs. 6.6%, p<0.001), wound infection (30% vs. 6.6%, p=0.012), sepsis (13.3% vs. 3.3%, p=0.04), and mesh extraction (10% vs. 0%, p=0.041) were markedly higher in the onlay group. Recurrence rates favored sublay repair (3.3% vs. 6.6%, p=0.55). Conclusion: Sublay mesh repair demonstrates lower complication rates, reduced infectious morbidity, and improved recurrence outcomes compared with onlay repair, supporting its preferential use when surgical expertise and operative resources permit.
