Inguinal Hernia Overview

---

 

Introduction

An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. This condition results in a bulge that can be painful, especially during activities like coughing, bending over, or lifting heavy objects. However, many hernias do not cause pain.

Prevalence

• Common condition
• Estimated occurrence: 27% in men and 3% in women
• Can occur at any age
• Present at birth or develop over time

Causes

• Increased pressure on abdominal muscles
• Activities contributing to development:
  • Straining during bowel movements
  • Long-term coughing
  • Being overweight
  • Lifting heavy weights

Symptoms

• Bulge in the area on either side of the pubic bone
• Burning or aching sensation at the bulge
• Pain or discomfort in the groin
• Heavy or dragging sensation in the groin
• Weakness or pressure in the groin

Risks and Complications

• Danger if not improved on its own
• Life-threatening complications possible
• Incarcerated hernia: Contents trapped in the abdominal wall
• Strangulated hernia: Cut-off blood flow to trapped tissue
• Signs of a strangulated hernia include nausea, vomiting, fever, and sudden pain

Treatment

• Typically involves surgery
• Surgery aims to push the bulge back and strengthen the abdominal wall
• Recommended for pain, severe or persistent symptoms, or serious complications

Gender Specific Prevalence

• More common in men than in women
• Anatomical differences as a cause
• Men’s inguinal canal: A preexisting opening that can be more easily reopened

Classification of Inguinal Hernias

---

 

Types Based on Location and Nature

• Indirect Inguinal Hernia:

  • Protrudes through the internal inguinal ring into the inguinal canal.
  • Often lateral to the inferior epigastric vessels.
  • May extend into the scrotum.

• Direct Inguinal Hernia:

  • Protrusion through the transversalis fascia within Hesselbach’s triangle.
  • More common in older patients.
  • Associated with abdominal wall laxity or increased intra-abdominal pressure.

Nyhus Classification System

• Widely used for classifying inguinal hernias.
• Based on location, size, and whether the hernia is primary or recurrent.

Nyhus Types

• Type 1: Normal inguinal ring with a peritoneal sac in the inguinal canal.
• Type 2: Enlarged deep inguinal ring, intact posterior wall, sac not in the scrotum.
• Type 3: Defects in the posterior wall (inguinal floor).
  • Type 3a: Direct hernia with posterior floor defect only.
  • Type 3b: Indirect hernia with enlargement of the deep inguinal ring and posterior floor defect.
  • Type 3c: Femoral hernia.
• Type 4: Recurrent hernia.

Aachen Classification System for Inguinal Hernias

• The Aachen Classification System is designed for categorizing inguinal hernias.
• It distinguishes hernias based on anatomical location and includes a grading system by measurement.

Categories of Hernias

1. Indirect Hernia: Protrusion through the internal inguinal ring, often extending into the inguinal canal or scrotum.
2. Direct Hernia: Protrusion through a weakened area in the anterior wall of the inguinal canal.
3. Scrotal or Giant Hernia: Large hernias that extend into the scrotum.
4. Femoral Hernia: Herniation through the femoral canal, more common in women.
5. Others/Rare Hernias: Uncommon types not fitting into the above categories.

Adoption by European Hernia Society (EHS)

• The EHS has endorsed a simplified version based on the Aachen classification.
• Aimed at standardizing intraoperative descriptions and facilitating comparison in medical literature.
• Promotes systematic use for better consistency and clarity in research and clinical practice.

Differentiation at Surgery

• Direct and indirect hernias differentiated by the position relative to the inferior epigastric vessels.
• Nearly all pediatric inguinal hernias are indirect.

Treatment Choice

• Depends on type, severity, and complications.
• Surgical repair, either open or minimally invasive, is primary treatment.

Preoperative Planning and Diagnosis

• Nyhus classification aids in individualized, type-related repair approach.
• Surgical approaches: Open surgery or laparoscopic techniques.
• Preoperative classification accuracy varies.
  • Methods include clinical examination, Doppler ultrasonography, and diagnostic laparoscopy.
  • Laparoscopy has high sensitivity and specificity for classification.

Classification by Etiology and Anatomy

• Etiology: Divided into congenital and acquired.
• Anatomic Location: Identified as direct and indirect inguinal hernias, and femoral hernias.

Congenital Hernias

• Inguinal Hernia: Caused by failure of the processus vaginalis to close.
  • In Males: Associated with testicular descent; failure of internal ring closure.
  • In Females: Involves the gubernaculum and ligaments related to the ovaries and uterus.
• Femoral Canal Hernia: Less common in congenital cases.

Acquired Hernias

• Result from weakening or disruption of fibromuscular tissues.
• Contributing Factors:
  • Chronic conditions (e.g., cough, constipation).
  • Connective tissue abnormalities.
  • Abdominal aortic aneurysm.
  • Pharmacologic effects (e.g., glucocorticoids).
  • Increased intraabdominal pressure (e.g., pregnancy, heavy lifting).

Indirect Inguinal Hernia

• Most common type in both sexes.
• Protrudes at the internal inguinal ring.
• Lateral to the inferior epigastric artery.
• More frequent on the right side in both sexes.

Direct Inguinal Hernia

• Protrudes medial to the inferior epigastric vessels within Hesselbach’s triangle.
• Associated with weaknesses in the floor of the inguinal canal.

Femoral Hernia

• Located inferior to the inguinal ligament, protruding through the femoral ring.
• More common in women.
• Higher risk of incarceration or strangulation.

Diagnosis of Inguinal Hernia

---

 

Physical Examination

• Primary method for diagnosing an inguinal hernia.
• Doctor checks for a bulge in the groin area.
  • More noticeable when standing, coughing, or straining.
• Examination typically performed with the patient standing and the physician seated.
• Sensitivity of 75%, specificity of 96% for diagnosis by surgeons.

Imaging Tests

• Used if diagnosis is not apparent from physical examination.
• Types of imaging tests:
  • Abdominal ultrasound: Non-invasive, inexpensive, high sensitivity, and specificity.
  • CT scan.
  • MRI.
• Ultrasound is generally better for diagnosing inguinal hernias.
• MRI is most sensitive for diagnosing occult inguinal hernias.

Special Considerations in Children

• Manual pressure may be applied to reduce the bulge.
• Surgery considered if manual reduction is not successful.

Importance of Professional Evaluation

• Not all inguinal hernias are visible or cause discomfort.
• Any noticeable bulge in the groin should be evaluated by a healthcare professional.

Summary

• Diagnosis is primarily clinical, based on physical examination.
• Imaging studies are supplemental, particularly in unclear cases.
