Abstract

Objective: To compare the outcomes of Onlay mesh technique versus Sublay mesh technique in patients undergoing ventral hernia repair.

Study Design: Randomized controlled trial Place & Duration: Study conducted in the department of surgery Khairpur Medical College (KMC) Hospital, Khairpur Mirs for six months during 1st July 2019 to 30th December 2019.

Methods: A total of 140 patients with both genders having ages 18 to 70 years whom were undergoing ventral hernia repair were included. Patients demographic including age, gender were recorded after informed consent. Patients were equally divided into two groups Group A and Group B. Group A patients received onlay mesh technique and Group B received sublay technique. Outcomes such as post-operative pain, wound infection, seroma formation and hospital stay were recorded and compare the results between both groups.

Results: There were 39 (55.71%) and 37 (52.86%) patients were females in Group A and B. Paraumbilical was the commonest type of hernia between both groups. There was significant difference in term of post-operative pain 5.23+1.54 vs 3.01+1.01 (P-value <0.05), wound infection found in 11 (15.71%) vs 5 (7.14%) patients in both groups. 6 (8.57%) patients in Group A and 2 (2.86%) patients in Group B found to had seroma (p=<0.05). Mean Hospital stay in days was high in Group A patients compared to Group B 4.01+1.95 vs 2.01+0.65 (p=<0.05).

Conclusion: We concluded that sublay mesh technique for ventral hernia repair was safe and effective with very low rate of complications as compared to onlay mesh procedure.
