Inguinal hernia examination

Introduction

  • Wash hands; Introduce self; ask Patient’s name, DOB and what they like to be called; Explain examination and obtain consent
  • Get a chaperone
  • Expose patient from waist down and ask them to stand up
  • Put on gloves

Inspection

  • General
    • Patient: well/unwell, pain/discomfort (incarceration), pallor, muscle wasting/cachexia, abdominal distension (obstruction)
    • Around bed: vomit bowls
  • Local
    • Lumps: size, shape, position, scrotal extension
    • Observe cough impulse

Palpation

  • Scrotal contents: palpate from anteriorly. If a lump is present, determine if you can get above it.
  • Lump/inguinal area (both sides): palpate from laterally, with one hand on the patient’s back, using the other to feel the lump/inguinal ligament region

Describe lump (SSSCCCTTT): Site, Size, Shape, Consistency, Contours, Colour, Tenderness, Temperature (Transillumination not required here)

  • Feel cough impulse (on each side separately): compress lump/inguinal area firmly. Ask the patient to turn their head to the opposite direction and cough. If the swelling becomes tense and expands, there is a positive cough impulse.
  • Reducibility:
    • Locate the deep inguinal ring (midway between ASIS and pubic tubercle)
    • Press firmly on the lump and, starting inferiorly, try to lift it up and compress it towards the deep inguinal ring 
    • Once it is reduced, slide your fingers up and maintain pressure over the deep inguinal ring
    • Ask patient to cough
    • If the hernia reappears, it is a direct hernia; if not, it is an indirect hernia
    • Release and watch hernia reappear if it has not already done so (indirect will slide down obliquely; direct will project forwards)

NB: If you cannot reduce the hernia, try again with patient lying supine.

Percussion and auscultation

  • Percuss and auscultate lump: this may reveal if bowel is present in a hernia

To complete

  • Thank patient and restore clothing
  • ‘To complete my examination, I would perform a full abdominal examination.’ 
  • Summarise and suggest further investigations you would consider after a full history
