Abstract

Background: Inguinal hernia is most common anterior abdominal wall hernia and affects all ages with male predominance.The main cause of inguinal hernia is increased abdominal pressure and muscle weakness of abdominal wall. Diagnosis of inguinal hernia is mostly made by clinical examination. Herniotomy, herniorrhaphy, hernioplasty by open operation and laparoscopic procedures is the operative treatment.

Results: Highest number of patients belongs to 41-60 years age group (42.8%). 94.6 % were male and 5.3 % were female patients.
