Management of Hernias
The management of hernias should be primarily surgical, with elective repair recommended for symptomatic hernias to avoid the significantly higher morbidity associated with emergency repairs. 1, 2
Types of Hernias and Diagnosis
Common types:
- Inguinal (most common)
- Femoral
- Umbilical/Paraumbilical
- Incisional
- Parastomal
- Diaphragmatic/Hiatal
Diagnostic approach:
Management Algorithm
1. Emergency Presentation
For patients with signs of strangulation, incarceration, or obstruction:
Immediate surgical intervention is required to prevent life-threatening complications 2
Signs requiring emergency surgery:
- Severe pain
- Irreducible hernia
- Signs of bowel obstruction
- Systemic symptoms (fever, tachycardia)
- Skin changes over hernia (erythema, necrosis)
Surgical approach:
- Laparoscopic or open repair based on patient condition and surgeon expertise
- May require bowel resection if ischemic/necrotic tissue is present 2
2. Elective Management
For reducible, non-emergency hernias:
Surgical repair is recommended for most symptomatic hernias 2
Conservative management is generally inappropriate and associated with increased risk of emergency presentation 2
Surgical options based on hernia type:
Inguinal/Femoral hernias:
- Mesh repair is standard of care
- Local anesthesia can be used in elderly/high-risk patients 2
Parastomal hernias:
- Small, reducible hernias: hernia belt may be used 1
- Elective repair for significant pouching issues, pain, or recurrent bowel obstruction
- Mesh repair often required to reduce recurrence risk 1
Diaphragmatic/Hiatal hernias:
3. Complex Hernias
For hernias with complicating factors:
Complex hernia criteria include factors related to 4:
- Size and location
- Contamination/soft tissue condition
- Patient history/risk factors
- Clinical scenario
Management principles:
Post-operative Care and Follow-up
Monitor for complications:
- Recurrence (3-5% of cases) 3
- Surgical site infection
- Chronic pain
- Mesh-related complications
Recurrence classification 5:
- Grade 0: No recurrence
- Grade I: Asymptomatic recurrence
- Grade II: Symptomatic recurrence requiring elective or no repair
- Grade III: Symptomatic recurrence requiring urgent repair
- Grade IV: Life-threatening complications related to recurrence
- Grade V: Death related to hernia recurrence
Special Considerations
Parastomal Hernias
- Occur in up to 50% of ostomates within 5 years 1
- Risk factors: obesity, smoking, steroid use, transverse colostomies 1
- Prevention: place stoma through rectus muscle 1
- Most effective repair is ostomy reversal when possible 1
- Recurrence after repair is common (>25% at 2 years) 1
Hiatal Hernias
- Laparoscopic revisional surgery for recurrent hiatal hernias is safe and effective 6
- Proton pump inhibitor therapy should be continued after repair in patients with Barrett's esophagus 3
- Surveillance intervals for Barrett's esophagus: every 3-5 years for non-dysplastic cases 3
Pitfalls and Caveats
- Avoid conservative management for symptomatic hernias as this is a key contributing factor in delayed treatment and increased morbidity 2
- Emergency hernia repair carries significantly higher complication rates, longer hospital stays, and increased risk of bowel resection compared to elective repair 2
- Inadequate mesh fixation can lead to mesh migration and recurrence 3
- Missed diagnosis of short esophagus in hiatal hernias may require additional procedures like Collis gastroplasty 3
- Moving the stoma when repairing parastomal hernias has fallen out of favor due to high risk of hernia at the new location 1
