What are the recommendations for umbilical hernia repair in a female of childbearing age considering pregnancy?

Umbilical Hernia Repair Prior to Pregnancy

For women of childbearing age planning pregnancy with an umbilical hernia, elective repair should be performed before conception if the hernia is large or symptomatic, followed by a 1-2 year waiting period before attempting pregnancy to allow complete healing and hormonal stabilization.

Clinical Decision Algorithm

For Non-Pregnant Women Planning Future Pregnancy

Large or Symptomatic Hernias:

• Proceed with elective repair before conception, then delay pregnancy for 1-2 years 1, 2
• This interval allows for complete wound healing, hormonal stabilization, and return to normal body weight 1
• Use mesh repair rather than suture-only repair to minimize recurrence risk during subsequent pregnancy 1

Small, Asymptomatic Hernias:

• Consider delaying repair until after delivery or after the last planned pregnancy 1, 2
• This approach is reasonable if the hernia is minimally symptomatic and not affecting quality of life 2

Critical Risk Factors to Assess

Diastasis Recti:

• Diastasis recti is very frequent in pregnancy and significantly increases recurrence risk, especially after suture repairs 1
• Mesh repair should be strongly considered in patients with rectus diastasis rather than primary suture repair 1

Pregnancy-Related Considerations:

• Pregnancy increases intra-abdominal pressure progressively, which can cause herniation or make preexisting hernias apparent 1
• The incidence of umbilical hernia among pregnancies is 0.08% 1
• Suture-only repairs carry high recurrence risk during pregnancy 1

Surgical Approach Recommendations

Mesh vs. Suture Repair:

• Laparoscopic mesh repair should be offered whenever possible for pre-pregnancy repairs 2
• Mesh repairs significantly reduce recurrence risk compared to suture repairs, particularly important given the mechanical stress of pregnancy 1, 2
• Suture repair may only be suitable for very small hernias 2

If Hernia Develops During Pregnancy

Emergency Situations:

• If incarceration or strangulation occurs, emergency repair is mandatory regardless of pregnancy status 1, 2
• 58% of pregnant patients requiring umbilical hernia repair present with incarceration or strangulation 3

Non-Complicated Hernias:

• Small, asymptomatic hernias can be managed with watchful waiting until delivery 1, 2, 4
• If symptomatic and affecting quality of life, repair in the second trimester is the optimal timing 1, 2
• Postpartum repair can be performed as early as 8 weeks after delivery, though waiting 1 year provides smoother convalescence 1
• Repair at time of cesarean section is a feasible option 1, 5

Outcomes Data

Safety Profile:

• Umbilical hernia repair during pregnancy can be performed with minimal morbidity to mother and baby 1
• In a series of 12 pregnant patients managed with watchful waiting followed by postpartum repair, no incarceration, strangulation, or delivery complications occurred 4
• Open umbilical hernia repair in pregnant patients (95% of cases) has superficial surgical site infection as the most common complication 3
• No hernia recurrences occurred in patients who underwent postpartum repair, including four who had subsequent uncomplicated pregnancies 4

Common Pitfalls to Avoid

• Do not perform suture-only repair in women planning pregnancy—the high recurrence risk during pregnancy makes mesh repair strongly preferred 1
• Do not ignore diastasis recti—this significantly increases recurrence risk and mandates mesh repair 1
• Do not rush pregnancy after repair—allow 1-2 years for complete healing and hormonal stabilization 1
• Do not delay emergency repair if incarceration or strangulation occurs—this is mandatory regardless of pregnancy status 1, 2
