Abstract
OBJECTIVES:
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".
DESIGN:
Retrospective autopsy study.
SETTING:
The pathology department and the department of surgery theatres of the Korle Bu Teaching hospital in Accra, Ghana
SUBJECTS:
Consecutive 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.
RESULTS:
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).
CONCLUSION:
The position of the normal appendix in Ghana differs from Western literature. The retrocaecal position appears less prone to inflammation in Ghanaians.
