37. Direct Inguinal Hernia- Medial and Lateral
A direct inguinal hernia is an acquired abdominal wall defect where intestinal tissue pushes through a weakened area of the abdominal muscle (Hesselbach’s triangle) in the groin. Common in older men due to aging, it causes a visible bulge that is often painless, yet painful or enlarged when coughing, lifting, or straining. Surgery (often mesh repair) is the primary treatment.
