CHAPTER 12 Abdominal wall and hernia

Herniae

Types of hernia

Inguinal hernia

This is the most common form of hernia. There are two types: indirect and direct.

Direct

This is acquired. The defect occurs in the abdominal wall, in Hesselbach’s triangle (bounded by the inguinal ligament inferiorly, the inferior epigastric artery laterally and the lateral border of rectus muscle medially). It is due to a weakness of the transversalis fascia in the posterior wall of the inguinal canal. It is often bilateral and occurs in the older patient and may be associated with obesity, cough, constipation, prostatism.

Both types may occur and straddle the inferior epigastric artery, the so-called ‘pantaloon’ hernia.
