Study Notes
Ventral Hernias and Their Specific Types
- A ventral hernia occurs through the front wall of the abdomen and includes umbilical and incisional hernias.
- Epigastric hernias are ventral hernias located above the belly button.
- Spigelian hernias are rare protrusions of abdominal contents through a defect in the spigelian fascia.
- Lumbar hernias occur through defects in the lumbar muscles or posterior fascia, below the 12th rib and above the iliac crest.
- Inguinal hernias are common due to the anatomical arrangement of muscular and fascial layers in the lower abdomen.
- History of pain, swelling, or presence of a mass in the groin area is significant in diagnosing hernias.
- Examination for inguinal hernias involves observation, palpation, and coughing to reveal a bulge or abnormal motion.
- Indirect inguinal hernias result from a persistence of the processus vaginalis through the internal ring, leading to a hernia sac.
- Direct inguinal hernias develop medial to the internal inguinal ring, and rarely extend into the scrotum.
- Specific types of inguinal hernias include Littre’s, Amyand, and Richter hernias.
- Femoral hernias exit from the retroperitoneal space along the femoral vessels and can be confused with inguinal canal hernias.
- Strangulation, incarceration, reducible, and irreducible are important terminologies and pathogenesis in the clinical significance of hernias.
