Hernia Hernia in Special Populations 1 — Questions and Answers
Question 1: At what age do umbilical hernias in children typically close spontaneously?
- By 6 months
- By 3–4 years of age (Correct answer)
- By 10 years
- They never close without surgery
Correct answer: By 3–4 years of age
Most umbilical hernias in children close spontaneously by 3–4 years of age as the abdominal wall musculature strengthens.
Question 2: Which hernia is more common in women than in men relative to all groin hernias?
- Inguinal hernia
- Femoral hernia (Correct answer)
- Umbilical hernia
- Hiatal hernia
Correct answer: Femoral hernia
While inguinal hernias predominate in both sexes, femoral hernias represent a proportionally larger share of groin hernias in women due to their wider pelvis.
Question 3: Why are hernias during pregnancy more likely to become symptomatic?
- Hormones dissolve fascial tissue permanently
- The growing uterus increases intra-abdominal pressure, enlarging pre-existing defects (Correct answer)
- Pregnancy causes immune suppression of the abdominal wall
- Fetal movement directly tears the abdominal wall
Correct answer: The growing uterus increases intra-abdominal pressure, enlarging pre-existing defects
The enlarging uterus progressively raises intra-abdominal pressure throughout pregnancy, causing pre-existing hernias to enlarge or become symptomatic.
Question 4: Hernia repair in premature infants is typically approached how?
- Deferred until age 2 years
- Repaired shortly after diagnosis due to high strangulation risk (Correct answer)
- Managed with a hernia truss until adulthood
- Treated with medications alone
Correct answer: Repaired shortly after diagnosis due to high strangulation risk
Inguinal hernias in premature infants carry high strangulation risk and are typically repaired promptly, though timing is individualized based on the infant's clinical stability.
Question 5: Elderly patients undergoing hernia repair face which anesthesia-related challenge?
- They require higher anesthetic doses universally
- They have increased sensitivity to anesthetic agents and higher risk of post-operative cognitive dysfunction (Correct answer)
- They heal faster than younger patients
- They have lower pain perception and need less analgesia
Correct answer: They have increased sensitivity to anesthetic agents and higher risk of post-operative cognitive dysfunction
Elderly patients metabolize anesthetic drugs more slowly and are at greater risk for post-operative delirium and cognitive dysfunction, favoring local or regional anesthesia when possible.
Question 6: What is the preferred management of a large paraesophageal hiatal hernia (>50% of stomach in chest) in a fit patient?
- Watchful waiting with antacids
- Elective laparoscopic surgical repair (Correct answer)
- Emergency open repair only
- Long-term proton pump inhibitors without repair
Correct answer: Elective laparoscopic surgical repair
Large paraesophageal hernias carry risk of acute gastric volvulus and strangulation, so elective laparoscopic repair is recommended in patients who can tolerate surgery.
