Hernia Types of Hernias 2 — Questions and Answers
Question 1: What distinguishes a direct inguinal hernia from an indirect inguinal hernia?
- Direct passes through the internal ring; indirect does not
- Indirect passes through the internal ring; direct protrudes through the posterior wall of the inguinal canal (Correct answer)
- Direct hernias only occur in women
- Indirect hernias never reach the scrotum
Correct answer: Indirect passes through the internal ring; direct protrudes through the posterior wall of the inguinal canal
An indirect inguinal hernia passes through the internal inguinal ring, while a direct hernia protrudes through Hesselbach's triangle in the posterior canal wall.
Question 2: A sliding hiatal hernia means that part of the stomach slides through the hiatus. What is the other major type of hiatal hernia?
- Rolling (paraesophageal) hernia (Correct answer)
- Incisional hernia
- Femoral hernia
- Richter hernia
Correct answer: Rolling (paraesophageal) hernia
The paraesophageal (rolling) hiatal hernia occurs when the stomach fundus rolls up alongside the esophagus into the chest.
Question 3: Which hernia involves only part of the bowel wall circumference becoming trapped, often without bowel obstruction?
- Sliding hernia
- Richter hernia (Correct answer)
- Spigelian hernia
- Umbilical hernia
Correct answer: Richter hernia
A Richter hernia involves only the antimesenteric wall of the bowel, so obstruction may be absent but strangulation risk is high.
Question 4: An obturator hernia passes through which opening?
- Femoral ring
- Obturator foramen (Correct answer)
- Inguinal canal
- Hiatus of the diaphragm
Correct answer: Obturator foramen
An obturator hernia protrudes through the obturator foramen in the pelvis and is most common in elderly, thin women.
Question 5: Lumbar hernias typically occur through which two regions?
- Groin and navel
- Petit's triangle and Grynfeltt-Lesshaft triangle (Correct answer)
- Inguinal canal and femoral ring
- Diaphragm and abdominal wall
Correct answer: Petit's triangle and Grynfeltt-Lesshaft triangle
Lumbar hernias emerge through either Petit's inferior lumbar triangle or the Grynfeltt-Lesshaft superior lumbar triangle.
Question 6: What term describes a hernia containing a Meckel diverticulum?
- Richter hernia
- Amyand hernia
- Littre hernia (Correct answer)
- Pantaloon hernia
Correct answer: Littre hernia
A Littre hernia is defined by the presence of a Meckel diverticulum within the hernial sac.
