Hernia Repair Management

Emergency vs. Elective Repair Decision

Immediate surgical repair is mandatory for incarcerated hernias with suspected intestinal strangulation to prevent bowel ischemia and death. 1

Emergency Indications (Operate Immediately)

  • Signs of strangulation: peritonitis, bowel ischemia, or intestinal necrosis require emergency hernia repair without delay 1
  • Incarcerated abdominal wall hernias with suspected compromise 1
  • Femoral hernias should undergo timely mesh repair due to higher strangulation risk 2

Elective Repair Indications

  • All symptomatic hernias should be treated surgically 3
  • All inguinal hernias in women should be operated on due to higher risk of femoral hernia and complications 3, 4
  • Asymptomatic or minimally symptomatic male inguinal hernias may be managed with watchful waiting, as the risk of hernia-related emergencies is low (approximately 4 per 1,000 patients per year) 3, 5
    • Watchful waiting is particularly safe in patients under 50 years old, ASA class 1-2, with inguinal (not femoral) hernias and duration of signs >3 months 5
    • However, the majority will eventually require surgery, so surgical risks and watchful waiting strategy should be discussed 3

Surgical Approach Selection

For Abdominal Wall Hernias (Inguinal, Femoral, Incisional, Umbilical)

Mesh repair is recommended as first choice, with either open or laparoscopic technique depending on hernia type and patient stability. 3

Laparoscopic/Endoscopic Approach (Preferred When Appropriate)

  • Bilateral hernias: laparoscopic/endoscopic procedure is preferable 3, 4
  • All hernias in women: laparoscopic repair is suggested to decrease chronic pain risk and avoid missing femoral hernias 3
  • Stable patients without bowel compromise: minimally invasive approach offers faster recovery, lower chronic pain risk (10-12% vs higher with open), and cost-effectiveness 3, 6
  • Femoral hernias: timely mesh repair by laparoscopic approach is suggested when expertise is available 3

Open Approach Indications

  • Suspected bowel strangulation or necrosis requiring resection 7
  • Hemodynamically unstable patients 7
  • Contaminated surgical fields (perforation/bowel resection): suture repair preferred due to mesh infection risk 1
  • Lack of laparoscopic expertise or equipment 1
  • Primary unilateral hernias in men: can be treated by either open or laparoscopic surgery 3, 4

Specific Repair Techniques

Mesh Selection and Placement

  • Mesh repair is superior to tissue-suture repairs and should be used in almost all cases 3, 6
  • Lichtenstein repair (open anterior mesh) and laparoscopic techniques are best evaluated and have similar long-term efficacy 3, 6
  • Mesh overlap: should extend 1.5-2.5 cm beyond defect edge 1, 7
  • Large defects (>8 cm or >20 cm²): mesh reinforcement is necessary when tension-free primary closure is difficult 1, 2

Mesh Fixation

  • TEP (totally extraperitoneal) repair: mesh fixation is unnecessary in almost all cases 3
  • TAPP and TEP: fix mesh in M3 hernias (large medial) to reduce recurrence 3
  • Avoid tackers near pericardium in diaphragmatic hernia repair due to cardiac complication risk 1, 2

Tissue Repair (Non-Mesh)

  • Shouldice technique is first choice if tissue repair is selected after patient discussion 3
  • Reserved for contaminated fields or patient preference after informed consent 1, 3

Special Hernia Types

Diaphragmatic Hernias

  • Complicated diaphragmatic hernias: surgery is strongly recommended 1
  • Unstable patients: laparotomy approach 1, 2
  • Stable patients: minimally invasive (laparoscopic/thoracoscopic) approach 1, 2
  • Primary repair with non-absorbable sutures should be attempted when possible 1
  • Biological or biosynthetic meshes can be safely used in clean-contaminated/contaminated cases 1

Port Site Hernias

  • Laparoscopic approach preferred in stable patients 7
  • Open repair indicated for suspected bowel strangulation, necrosis, or hemodynamic instability 7

Anesthesia Selection

Local anesthesia is recommended for open inguinal hernia repair when surgeon expertise exists, offering many advantages including reduced viral aerosol risk. 1, 3

  • Local anesthesia: recommended for open repairs, particularly cost-effective in day-case settings 3, 6
  • Incarcerated inguinal hernia: local anesthesia can be used in absence of bowel gangrene 1
  • General anesthesia: suggested over regional in patients ≥65 years due to fewer complications (MI, pneumonia, thromboembolism) 3
  • Perioperative field blocks/infiltrations: recommended in all open repairs 3

Perioperative Management

Antibiotic Prophylaxis

  • Not recommended for average-risk patients in low-risk environments for open surgery 3
  • Never recommended for laparoscopic/endoscopic repair 3
  • Can be considered in centers with high wound infection rates 6

Day Surgery

  • Recommended for majority of groin hernia repairs provided aftercare is organized 3
  • Laparoscopic approach has median length of stay of 2 days vs 3 days for open 8

Recovery

  • Patients should resume normal activities without restrictions as soon as comfortable 3

Recurrent Hernia Management

After failed anterior repair, posterior repair is recommended; after failed posterior repair, anterior repair is recommended. 3

  • After failed anterior AND posterior approaches, management by specialist hernia surgeon is recommended 3
  • Recurrence rate after tension-free mesh repair in emergency settings is comparable to elective repair 5

High-Risk Patient Considerations

Mortality Risk Factors in Elective Ventral Hernia Repair

The following predict mortality and warrant consideration of conservative management 8:

  • Age >50 years (OR 1.96)
  • Congestive heart failure (OR 2.15)
  • Pulmonary circulation disorders (OR 5.26)
  • Coagulopathy (OR 3.93)
  • Liver disease (OR 1.89)
  • Metastatic cancer (OR 4.66)
  • Neurological disorders (OR 2.31)
  • Paralysis (OR 5.29)

Emergency Repair Risk Factors

Higher morbidity/mortality in emergency repair occurs with 5:

  • Age >49 years
  • Delay >12 hours between symptom onset and surgery
  • Femoral hernia location
  • Nonviable bowel
  • ASA class 3-4

Common Pitfalls

  • Chronic postoperative inguinal pain (CPIP) occurs in 10-12% of patients, with debilitating pain in 0.5-6% 3
  • CPIP risk factors: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia, open repair 3
  • Plug repair techniques not recommended due to higher erosion incidence 3
  • Learning curve: approximately 100 supervised laparoscopic repairs needed to achieve results comparable to open mesh surgery 3
  • Pregnant women: watchful waiting suggested as groin swelling often consists of self-limited round ligament varicosities 3
