Study Notes
Types of Groin Hernias
- Groin hernias are categorized into three types based on their location relative to the inguinal (Hesselbach) triangle: direct, indirect, and femoral hernias.
Direct Inguinal Hernia
- Involves protrusion of tissue through the posterior wall of the inguinal canal.
- Occurs medial to the inferior epigastric vessels and does not traverse the internal ring.
- Typically results from wear and tear or chronic straining.
- Commonly manifests in a globular shape.
Indirect Inguinal Hernia
- Characterized by tissue protruding through the internal inguinal ring, lateral to the inferior epigastric vessels.
- Usually caused by a patent processus vaginalis, a congenital defect.
- Usually appears piriform in shape.
Femoral Hernia
- Protrusion of tissue occurs below the inguinal ligament and medial to the femoral vessels.
- Higher likelihood of strangulation compared to other types of hernias.
Diagnostic Criteria
- Initial diagnostic method is ultrasonography.
- If suspicion remains high despite negative ultrasound, MRI is requested.
Management Strategies
- Watchful waiting is not recommended for symptomatic hernias or femoral hernias in non-pregnant women due to higher risks of incarceration and strangulation.
- Watchful waiting is more acceptable in pregnant patients due to potential self-limiting conditions.
Complications
- Richter hernia is a rare but dangerous complication where part of the intestinal circumference is entrapped and strangulated in the hernial sac, leading to high mortality rates.
Imaging Techniques
- Color flow Doppler imaging can differentiate between true hernias and round ligament varicosities.
Post-Operative Recommendations
- A period of inactivity for about 4-6 weeks is advised after hernia surgery.
Hesselbach Triangle
- The inguinal triangle (Hesselbach triangle) is defined by three anatomical landmarks:
- Medial: rectus abdominis
- Inferior: inguinal ligament
- Lateral: inferior epigastric vessels
