Abstract

Background: Abdominal hernia is the most common surgical alignment that affects all age groups and sexes. It is characterized by the protrusion of abdominal contents through the abdominal wall's muscles and fascia. In this study, the incidence, types, and associated factors of external abdominal hernias at Hiwotfana Comprehensive Specialized Hospital and Jugal Regional Hospital, eastern Ethiopia, were ascertained.

Objective: To identify the incidence, types, and associated factors of external abdominal hernia among adult patients who visited the surgical outpatient department of Hiwotfana comprehensive specialized hospital and Jugal regional hospital from 20 October to 5 December 2022.

Methods: A cross-sectional study was conducted from 20 October to 5 December 2022, on adult patients who visited the surgical outpatient department at the Hiwotfana Comprehensive Specialized Hospital and Jugal Regional Hospital in eastern Ethiopia. All adult patients who visited the surgical outpatient department of each hospital were enroled in the study using a stratified random sampling technique. Both descriptive and inferential statistics were conducted, and the results were presented in text, graphs, and tables. Odd ratios for the strength and directions of association were used with a 95% CI, and a P value of less than 0.05 was considered to declare statistical significance.

Result: A total of 403 participants were included in this study from two different governmental hospitals in Harar town, with a 100% response rate. The incidence of the external abdominal wall hernia was 41 (10.2%). The epigastric hernia had the highest prevalence (41.5%, n=17). Constipation [adjusted odds ratio (AOR)=2.91, CI=1.119-7.579), prolonged cough (AOR=3.993, CI=1.358-11.741), history of abdominal surgery (AOR=5.764, CI=1.837-18.083) and heavy lifting (AOR=5.476, CI=2.505-11.969) had statistically significant association (P≤0.05).

Conclusion: The incidence of external abdominal wall hernia in our area is similar to the other existing literature reported from different areas. Epigastric hernia is the most prevalent type of external abdominal hernia and is commonly encountered in female patients. Constipation, a prolonged cough, previous abdominal surgery, and heavy lifting are significantly associated with an external abdominal wall hernia.
