SU28.1-2 | Hernias — Summary & Reflection

KEY TAKEAWAYS

A hernia is the protrusion of a viscus through a defect in its containing wall, with a sac, contents and coverings. Groin hernias are classified by relating them to the inferior epigastric vessels and the pubic tubercle: an indirect inguinal hernia passes through the deep ring lateral to the vessels, is congenital and can reach the scrotum; a direct inguinal hernia bulges through Hesselbach's triangle medial to the vessels and is acquired; a femoral hernia lies below and lateral to the pubic tubercle, is commoner in women and most often strangulates. Hernias follow a continuum — reducible -> irreducible (incarcerated) -> obstructed -> strangulated — and a strangulated hernia (compromised blood supply) is a surgical emergency. Examination uses the cough impulse, reduction, the pubic-tubercle relation and the deep-ring occlusion test; the diagnosis is clinical, with ultrasound or CT for doubtful cases. Uncomplicated inguinal hernias are repaired electively with tension-free mesh — open Lichtenstein or laparoscopic TEP/TAPP (favoured for bilateral/recurrent) — while femoral hernias are always repaired and obstructed/strangulated hernias need emergency surgery with assessment of bowel viability.

REFLECT

Think back to a patient — real or simulated — with a groin lump. Did you examine them standing as well as lying, identify the pubic tubercle, look for a cough impulse and try to reduce the lump, and could you have confidently said whether the hernia was inguinal or femoral, indirect or direct? Now imagine the same patient returning at night with a tender, irreducible lump and vomiting: would you have recognised the shift along the reducible-to-strangulated continuum and acted with the urgency a strangulated hernia demands? Reflect on one habit you will build now — always examining both groins and the hernial orifices in any patient with abdominal pain or obstruction — so that you never miss the small, dangerous hernia.
