Evaluation and Management of Umbilical Hernia
Umbilical hernias require surgical repair in all symptomatic patients to prevent serious complications including incarceration, pressure necrosis, rupture, evisceration, and peritonitis. 1
Initial Evaluation
Physical examination findings to assess:
- Size of hernia defect (small <1 cm, medium 1-3 cm, large >3 cm)
- Size of hernia sac
- Calculate Hernia-Neck Ratio (HNR) = size of hernia sac/size of neck
- Presence of ascites (common in cirrhotic patients)
- Signs of complications (tenderness, erythema, irreducibility)
Imaging studies:
- Ultrasound: First-line imaging for uncomplicated hernias
- CT scan: Gold standard for complicated cases or when clinical diagnosis is uncertain
Risk Stratification
Patients with HNR >2.5 have significantly higher risk of complications (91% sensitivity, 84% specificity) and should be prioritized for surgical repair regardless of symptoms 2.
Management Algorithm
1. Non-Cirrhotic Patients
Asymptomatic small hernias (<1 cm):
- Watchful waiting with periodic follow-up
- Patient education on warning signs requiring urgent evaluation
Symptomatic hernias or hernias >1 cm:
2. Cirrhotic Patients with Ascites
Pre-surgical management:

3. Emergency Management of Complicated Umbilical Hernias
Indications for emergency surgery:
- Incarceration
- Strangulation
- Rupture with evisceration
- Peritonitis
Surgical approach:
- Emergent surgery by surgeon experienced in cirrhotic patient care
- Consultation with hepatologist for postoperative ascites control 5
- Consider incisional negative pressure wound therapy (iNPWT) to reduce wound complications in cirrhotic patients 6
- Consider postoperative TIPS if ascites cannot be controlled medically 5
Postoperative Care
General recommendations:
- Avoid lifting >10-15 pounds for 4-6 weeks 1
- Use proper body mechanics when movement is required
- Gradually increase activity as directed by surgeon
For cirrhotic patients:
- Strict sodium restriction (2 g/day or 90 mmol/day) 5
- Minimize IV maintenance fluids
- Close monitoring of ascites control
- Optimization of nutrition
Complications to Monitor
Early complications:
- Wound infection
- Seroma formation
- Ascites leakage (in cirrhotic patients)
- Recurrence of ascites leading to wound dehiscence
Late complications:
- Hernia recurrence (higher in suture repair vs. mesh repair)
- Chronic pain
- Mesh-related complications (infection, erosion)
Special Considerations
- Prosthetic mesh may reduce recurrence rates but increases infection risk in cirrhotic patients 5
- Rapid decline in ascitic fluid volume (e.g., after large volume paracentesis) can paradoxically cause incarceration 5
- Postoperative control of ascites is necessary for wound healing and prevention of secondary bacterial peritonitis 5
By following this structured approach to umbilical hernia management, clinicians can optimize outcomes and minimize complications in both cirrhotic and non-cirrhotic patients.
