To determine the normal (non-inflamed) position of the vermiform appendix in Ghana and carry out a pilot study to test the hypothesis "The retrocaecal appendix is less prone to inflammation".Retrospective autopsy study.The pathology department and the department of surgery theatres of the Korle Bu Teaching hospital in Accra, GhanaConsecutive autopsies and inflamed appendices at appendicectomy. Deaths occurring from untreated appendicitis were excluded from the autopsy study. Conversely non-inflamed appendices and appendices from interval appendicectomy were excluded from the appendicitis study.There were 1358 autopsies and 323 inflamed appendices. In the autopsy study the retrocaecal position was the most common (914 [67.3%]). Other positions were pelvic (294 [21.6%]), preileal (66 [4.9%]), postileal (51 [3.8%]) and paracaecal (33 [2.4%]). These positions were similar in males and females. The positions of 323 inflamed appendices were: retrocaecal (183 [56.7%]), pelvic (66 [20.4%]), preileal (20 [6.2%]), postileal (15 [4.6%]) and paracaecal (39 [12.1%]). Comparing the nonretrocaecal to the retrocaecal position by chi square, the non-retrocaecal position was more prone to inflammation (p<0.001).The position of the normal appendix in Ghana differs from Western literature. The retrocaecal position appears less prone to inflammation in Ghanaians.
