Abstract
Background: Acute appendicitis is a common surgical problem. Prompt and accurate diagnosis is essential for appropriate management. This relies not only on the understanding of the clinical features, but also on the knowledge of the variations in its anatomical position.
Patients and methods: In the present study, we have examined the position, length, and the extent of the mesoappendix of the vermiform appendix in patients seen in three private hospitals in Lagos state over a period of twelve calendar months. The features of interest were evaluated during appendicectomy.The variations in the anatomic features of appendix was compared between the two dominant tribes in Lagos Nigeria
Results: The pelvic appendix was commonest position (41.3%). The average length of the appendix was 11.5cm and the mesoappendix fail to reach the tip in 55%.
There were subtle anatomical variations of appendix between the two major tribes in patients that presented with acute appendicitis in three private hospitals in Lagos state. Appendix was 0.5cm longer in the Ibos; the incidence of appendicitis appeared relatively lower in Ibos. The position of the appendix in the Yoruba was mainly pelvic, while in the Ibo the pelvic and retrocaecal position occur in equal proportions.
The extent of mesentery did not appear to have any influence on the incidence of acute appendicitis.
Conclusion: There are no dramatic differences in the position and length of the vermiform appendix in the two major tribes in Lagos. The incidence of appendicitis was higher in the Yoruba’s probably because more Yoruba’s were seen and secondly because Lagos is the home of the Yoruba’s. Furthermore pelvic appendix was common in the Yoruba and as speculated may account for this difference.
Key Words: Appendicitis, vermiform appendix, position, length and variations among 2 ethnic groups.
