Background
In our communities there are large numbers of longstanding external hernias that remain untreated. This paper describes the epidemiological characteristics of these hernias. The data is expected to provide guidelines for sustained national and international efforts to reduce the burden of hernia by performing large-scale elective hernia repairs.
Method
Between January 1998 and December 2007, a simple pro-forma was designed and used to record, in a prospective manner, the age, sex of patient and anatomical site of all external hernias seen and operated on both as emergencies and non-emergencies. These were patients who presented to a single general and paediatric surgeon at the Komfo Anokye Teaching Hospital in Kumasi, Ghana.
Results
A total of 2,506 patients were studied, of which 1,930 were male and 576 female, giving a male:female ratio of 3.4:1. Inguinal hernia was seen in 1,766 patients: 1,613 males and 153 females, a male:female ratio of 10.5:1. Children 4 years old or younger accounted for 20.9% of inguinal hernias. Femoral hernia was seen in 79 patients: 70 females and 9 males. These groin hernias were diagnosed in 1,845 patients, accounting for 73.6% of all patients. Incisional hernia was diagnosed in 380 patients (15.2%): 179 males and 201 females—a male:female ratio of 1:1.1. These two hernia types (groin and incisional) were seen in 2,225 patients, representing 88.8% of all the patients studied. All other hernias studied, including para-umbilical, umbilical and epigastric, were seen in 281 patients, representing 11.2% of the hernias studied.
Conclusion
The epidemiology of external hernias seen and treated in our hospital is no different from that of hernias in other communities. Sustained efforts at elective repair will reduce the vast numbers of untreated accumulated hernias in our communities and thus prevent unnecessary morbidity and mortality.
