Background: Most common abdominal wall incisions are midline or paramedian and its closure technique should be efficient to provide strength for prevention of an incisional hernia and should be a barrier to infection. An incisional hernia is the most frequent complication as high as 39.9% after abdominal surgery. The integrity of sutured abdominal wound rests on the balance between suture holding a capacity of tissues and tissue holding capacity of sutures. Objective: The purpose of the study is to evaluate comparison between the mass closure and layered closure of midline and paramedian incisions for operative time and postoperative complications after performing single layered closure and conventional layered closure of laparotomy wounds like a seroma, wound infection, wound gaping, burst an abdomen and incisional hernia. Results: Meantime for the closure of laparotomy wound through a midline or Para median incision by single layered closure technique was 14 minutes, and by the layered closure, the technique was 23 minutes. There was a difference of 9 minutes statistically significant (p=0.001). In postoperative period patients closed by mass closure technique 8 patients (16%) had postoperative complications in the form of seroma in 2 patients (4%), infection in 3 patients (6%), wound gaping in 2 patients (4%) and incisional hernia in 1 patient (2%) and no patient had burst abdomen whereas in layered closure total 16 (32%) patients had complications as seroma in 5 patients (10%), wound infection in 4 patients (8%), gaping in 4 patients (8%) burst abdomen in 1 patient (2%) and incisional hernia in 2 patients (4%). Conclusion: Single layered closure technique is better than layered closure in term of operation time and postoperative complications like a seroma, infection, wound gaping, burst an abdomen and incisional hernia.
