Aims: This study investigates the histological appearance of appendixes from laparoscopic and open appendicectomies. We propose that the negativity rate of laparoscopic appendicectomies is when compared to an open appendicectomy due to the advancements in laparoscopic equipment and surgeon skills. Methods Retrospective data collection of all appendicectomies between January – June 2014. Data was collected from Theatre logbooks and the Pathology and PACS computer systems, and analysed in Microsoft Excel. Results 226 appendectomies were performed on the emergency-operating list. 174 (77%) had a laparoscopic appendicectomy and 52(23%) had an open procedure. The negative appendix rate on histology was significantly higher in the laparoscopic group (28.2%, n = 49) versus the open group (11.5%, n = 6) p = 0.05. There was a 2% (n = 5) associated morbidity and 0% mortality. Conclusion Laparoscopic surgery is considered to be a minimally invasive surgical procedure with low associated risks. The appendix is removed when inflamed and often in right iliac fossa pain when no other pathology is found. Our study shows that laparoscopy may be overused resulting in higher than expected negativity rates. Key statement Laparoscopic surgery is fast becoming the preferred operative procedure for the suspected appendicitis diagnostic tool in the unclear presentation of right iliac fossa pain. The minimally invasive procedure is considered to be a safe procedure perhaps resulting in its overuse. We investigate the negativity rate in laparoscopic verses open appendicectomy.
