Inguinal hernia

Extra-abdominal hernias that occur in the groin area are collectively referred to as inguinal hernias. Common ones include oblique inguinal hernias and straight inguinal hernias. Of these, oblique hernias are the most common, accounting for about 90% of all external abdominal hernias. The hernia sac protrudes through the outside of the inferior wall of the abdominal wall and the inguinal canal, diagonally inwardly, downwardly, and forward through the inguinal canal, and then out of the inguinal canal to enter the scrotum. It is more common in men, with a male to female ratio of about 15: 1, with the highest incidence in infants and the elderly. Straight inguinal hernia refers to the hernia formed by the internal organs protruding from the triangle of the straight hernia. It is more common in elderly men.
