Background: Paraumbilical hernia is a common anterior abdominal wall defect often requiring surgical intervention. Mesh reinforcement techniques, including onlay and inlay methods, are widely used in open repairs. However, there remains a lack of consensus on the superior technique for minimizing short-term postoperative complications.
Objective: To compare the short-term outcomes of onlay versus inlay mesh repair in patients undergoing open paraumbilical hernia surgery.
Methods: This randomized controlled trial was conducted at the Department of Surgery, Khyber Teaching Hospital, Peshawar, over six months. A total of 282 adult patients without comorbidities and with BMI ≤ 31 kg/m² were enrolled using consecutive sampling and randomized into two equal groups. Group A underwent onlay mesh repair, and Group B received inlay mesh repair. Short-term outcomes pain score using Visual Analogue Scale (VAS), wound infection, and seroma formation were evaluated on the 7th postoperative day. Statistical analysis was performed using SPSS v25 with p ≤ 0.05 considered significant.
Results: The mean postoperative VAS pain score was significantly lower in the onlay group (1.12 ± 0.76) compared to the inlay group (2.96 ± 1.49). Wound infection occurred in 3.5% of patients in Group A versus 12.8% in Group B. Seroma formation was noted in 1.4% of Group A and 8.5% of Group B. All differences were statistically significant.
Conclusion: Onlay mesh repair resulted in significantly better short-term outcomes than inlay repair in terms of postoperative pain, wound infection, and seroma formation, making it a preferable technique for open paraumbilical hernia repair.
