Background: Appendectomy, being the most common surgical procedure performed in general surgery, is still being performed by both open and laparoscopic methods due to a lack of consensus as to which is the most appropriate method. Because further trials are necessary and few such studies have been performed in developing countries, we decided to evaluate the outcomes of the 2 procedures to share our experience with the international community.
Methods: Consecutive patients with suspected acute appendicitis who underwent laparoscopic (LA) (n=48) and open (n=52) appendectomy (OA) over a period of 3 years were studied. Clinical outcomes were compared between the 2 groups in relation to operative time, analgesia used, length of hospital stay, return to work, resumption of a regular diet, and postoperative complications.
Results: Mean age of patients was 25.8 years in the laparoscopic and 25.5 years in the open group. Patient demographics were similar in both groups (P>0.05). There was significantly less need for analgesia (1.0+/-0.5 in LA and 1.5+/-0.6 doses in OA), a short hospital stay (1.4+/-0.7 in LA and 3.4+/-1.0 days in OA), early return to work (12.6+/-3.3 in LA and 19.1+/-3.1 days in OA), and less time needed to return to a regular diet (20.1+/-2.9 in LA and 22.0+/-4.7, P<0.05 in OA) in the laparoscopic appendectomy group. Operative time was significantly shorter (54.9+/-14.7 in LA and 13.6+/-12.6 minutes in OA) in the open group. Total number of complications was less in the laparoscopic group; however, there was no statistically significant difference.
Conclusion: The laparoscopic technique is a safe and clinically beneficial operative procedure. It provides certain advantages over open appendectomy, including short hospital stay, decreased requirement of postoperative analgesia, early food tolerance, and earlier return to normal activities. Where feasible, laparoscopy should be undertaken as the initial procedure of choice for most cases of suspected appendicitis.
