The aged old open appendectomy has been the main form of corrective surgery for patients who was diagnose with acute appendicitis. However, in the modern era, the laparoscopic approach has become more common and many have questioned its effectiveness and superiority over the appendectomy (Biondi, et al 2016). The laparoscopic approach has been identified for shorter recovery time post operatory, thus resulting in shorter hospital stay, less postoperative pain, faster return to daily activities.

OR= ad/bc
OR = (35×32) ÷ (8x5) =1120÷40 =28
