Background:Ventral abdominal hernias are common in surgical practice. This study was conducted to compare the results of onlay and preperitonealsublay mesh repair technique, with the variables like duration of surgery, suction drainage, hospital stay, seroma formation, surgical site infection and recurrence rate. Materials & Methods: The present study was conducted in the department of general surgery on 70 patients of with umblical hernia. Patients were divided into 2 groups ieonlay and sublay group. Primary outcome measures comparison of recurrence of hernia within 3 months after surgery between onlay and sublay mesh repair group, duration of surgery between two groups, duration of suction drainage in both groups, hospital stay, seroma formation and surgical site infection with in 1 month of surgery.Results: 31.4 percent (11 patients) of the patients of the Onlay group and 34.3 percent (12 patients) of the patients of the Sublay group belonged to the age group of 31 to 40 years. 42.9 percent of the patients (30 patients) had umbilical hernia, while 57.1 percent of the patients (40 patients) of the present study had para-umbilical hernia. Diabetes mellitus was seen in 4 in onlay and 6 in sublay group, obesity in 13 in onlay and 15 in sublay group and hypertension in 3 in onlay and 2 in sublay group. The mean operative time for the subjects of the Onlay group was 58.12 minutes and was significantly lower than subjects of the Sublay group, which was found to be 82.56 minutes (P- value < 0.05).Conclusion: Sublay mesh repair is associated with less chances of seroma formation and almost no recurrence with low post-operative complication like infection and wound edge necrosis.
Key words: Onlay,Sublay, Umbilical hernia.
