Abstract

Background. Topography of the appendix influences its mobility, degree of mobilization of the cecum, and need for additional muscle splitting during appendectomy. Although appendectomy is a common surgical procedure, there is a paucity of data on its topography in black Africans. Methods. The position and length of the appendix and relation of the appendicular base with spinoumbilical line were determined in 48 cadavers obtained from the Department of Human Anatomy, University of Nairobi, Kenya. Results. The commonest appendicular types in males were retrocecal 10 (27%) while in females was subileal 4 (36.4%). The average length of the appendix was 76.5 ± 23.6 mm. The base of the appendix was located along, below, and above the spinoumbilical line in 25 (52.1%), 9 (18.8%), and 14 (29.2%) cases, respectively. Conclusion. The topography of appendix in Kenyans shows variations from other populations. Knowledge of these variations is important during appendicectomy.

Highlights

The vermiform appendix is the most variable abdominal organ in terms of position, extent, peritoneal, and organ relations [1,2,3,4]
The length of the vermiform appendix is important in influencing the differential diagnosis of acute abdomen [2]
Ethnic and geographical variations have been reported regarding the position of the appendix (Table 1). This variable anatomy may pose a challenge during appendectomy because it may necessitate extension of a transverse incision or additional muscle splitting

Summary

Introduction

The vermiform appendix is the most variable abdominal organ in terms of position, extent, peritoneal, and organ relations [1,2,3,4]. Knowledge of the variations in the position of the vermiform appendix is important because, in appendicitis, its variable positions may produce variable symptoms and signs which mimic other diseases [5,6,7]. Ethnic and geographical variations have been reported regarding the position of the appendix (Table 1) This variable anatomy may pose a challenge during appendectomy because it may necessitate extension of a transverse incision or additional muscle splitting. Both these may complicate the surgery, prolong the operating time, and can affect the cosmetic outcome [9].
