Comparison of Open Appendectomy and Laparoscopic Appendectomy in Perforated Appendicitis.

Introduction Laparoscopic appendectomy for nonperforated appendicitis is associated with improved outcomes. This study compares laparoscopic appendectomy and open appendectomy in cases of a perforated appendix by assessing surgical site infection, mean operating time, and length of hospital stay. Materials and methods This study was a prospective randomized study conducted at the Department of Surgery, Holy Family Hospital, Rawalpindi, Pakistan, from January 2016 to January 2017, by randomly allotting the laparoscopic or the open appendectomy technique to 130 patients by the lottery method. Patients having a perforated appendix were included after they provided informed consent. Data were entered and analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY, US). Results The frequency of wound site infection was significantly higher in open appendectomy (27.69%) than in the laparoscopic approach (10.77%; p=0.01). Mean hospital stay was slightly longer in the laparoscopic approach (4.38 ± 1.09 days) than in open appendectomy (4.18 ± 0.77 days; p=0.23). Mean operating time for laparoscopic appendectomy and open appendectomy was 46.98 ± 2.99 minutes and 53.02 ± 2.88 minutes, respectively (p<0.000). Conclusion Laparoscopic appendectomy was associated with fewer surgical site infections and shorter mean operating time than an open appendectomy.
