What is the key difference between a direct and an indirect inguinal hernia?
What is the key difference between a direct and an indirect inguinal hernia?
- A direct inguinal hernia is not identifiable on physical examination, while an indirect inguinal hernia is easily diagnosed.
- A direct inguinal hernia protrudes through the posterior wall of the inguinal canal, while an indirect inguinal hernia protrudes through the deep inguinal ring. (correct)
- A direct inguinal hernia is associated with bowel obstruction, while an indirect inguinal hernia is reducible.
- A direct inguinal hernia involves the scrotum, while an indirect inguinal hernia does not affect the scrotal area.

What defines a complicated inguinal hernia?
What defines a complicated inguinal hernia?
- The hernia is reducible and not associated with any complications.
- It is directly palpable on physical examination.
- Complicated hernias always involve the scrotum.
- The hernia is irreducible or associated with mechanical bowel obstruction or strangulation. (correct)

Study Notes
Inguinal Hernia
- May not be apparent until adulthood, despite being present since birth
- Location: lateral to the inferior epigastric blood vessels, outside the Hesselbach triangle
- Path: runs from the deep inguinal ring through the inguinal canal to the superficial inguinal ring
- Associated structures: surrounded by the external spermatic fascia, cremasteric muscle fibers, and internal spermatic fascia
Clinical Features
- Uncomplicated inguinal hernia:
- Typically manifests as an ill-defined mass in the inguinal region
- Increases in size when coughing or straining
- Decreases in size on lying supine
- Inguinal pain or vague inguinal discomfort that increases with physical activity
- May be painless
- Inguinodynia with no palpable groin mass is typically the only manifestation of an occult inguinal hernia
Physical Examination
- Ask the patient to perform the Valsalva maneuver and observe for an expansile cough impulse in the inguinal region
- Palpate the inguinal canal
- In male patients: invaginate the scrotal skin toward the superficial inguinal ring with the index or little finger
- In female patients: palpate the area over the inguinal ligament
- Ask the patient to perform the Valsalva maneuver
- A palpable bulge confirms the diagnosis of an inguinal hernia
Complicated Inguinal Hernia
- Incarcerated hernia:
- The hernia is irreducible
- Skin overlying the hernia: normal
- Obstructed hernia:
- Symptoms of mechanical bowel obstruction
- Sudden onset of pain, nausea, vomiting, abdominal distention, constipation, or obstipation
- Strangulated hernia:
- Sudden, severe groin pain caused by constriction and ischemia (or necrosis) of hernial contents
- Signs of sepsis or signs of shock
- Features of bowel obstruction if the hernia contains intestinal loops
- Skin overlying the hernia: warm, erythematous, tender, and may appear exfoliated or blistered
Clinical Evaluation
- Medical history should include:
- Identification of typical clinical features (e.g., of uncomplicated inguinal hernia)
- Onset and duration of symptoms
- Evaluation of risk factors for an acquired inguinal hernia
- Physical examination should include:
- Palpation of the inguinal canal
- Evaluation for signs of complicated inguinal hernia
- Identification of signs of underlying etiologies, e.g., ascites, BPH
Imaging Indications
- Uncertain clinical diagnosis
- Suspected recurrent or occult inguinal hernia
- Consider preoperative imaging for complicated inguinal hernia
