INTRODUCTION: Appendicectomy is by far the commonest major emergency general surgical operation and Iaparoscopic appendicectomy is now becoming common. The question of whether a normal-looking appendix should be removed Iaparoscopicaiiy is more pertinent than ever before. PATIENTS AND METHODS: A retrospective study was undertaken to review the histopathology results and compare macroscopic with microscopic descriptions of all patients who underwent an appendicectomy, either by open surgery or Iaparoscopicaiiy, over a 1-year period from 1 September 2004 to 31 August 2005. RESULTS: A total of 199 appendicectomies were carried out in the year of which histopathology results for 190 could be retrieved. Of the 190 who had an appendicectomy, 110 (57.9%) were female and 80 (42.1%) were male. While appendicitis was confirmed histologically in 65 of 80 (81.2%) male patients, it could only be confirmed histologically in 57 of 110 (51.8%) female patients. However, in a large number of female patients in whom macroscopically normal appendices had been removed, other findings were noted including fibro-obliterative changes in 10, luminal inflammation in 6, serositis in 5, lymphoid hyperplasia in 3, feacoliths in 2, and pinworm in 1, making another abdominal pathology a possibility. CONCLUSIONS: The number of macroscopically normal appendices removed was much larger in female patients. However in 27 of 49 normal looking appendices in females, findings such as serositis, luminal inflammation, lymphoid hyperplasia, etc. were noted on histology, suggesting that another abdominal pathology may have been missed or the appendix may still have been the cause for pain. On the basis of these findings, we suggest that diagnostic laparoscopy should be performed at least in all female patients before an appendicectomy; if no other findings are noted on laparoscopy, it is likely to be worthwhile to remove the appendix.
