Treatment for Inguinal Hernia
Surgical repair is the definitive treatment for inguinal hernias, with mesh repair being the recommended standard approach for non-complicated inguinal hernias. 1, 2
Assessment and Classification
- Determine if the hernia is reducible or incarcerated/strangulated, which guides the urgency and approach of surgical intervention 2
- Systemic inflammatory response syndrome (SIRS), contrast-enhanced CT findings, lactate levels, and D-dimer levels can help predict bowel strangulation in complicated cases 1
- Delayed diagnosis (>24 hours) is associated with significantly higher mortality rates in patients with strangulated inguinal hernias 2
Treatment Algorithm
Non-complicated Inguinal Hernias
- Mesh repair is strongly recommended as the standard approach for all non-complicated inguinal hernias 1, 2
- Two main surgical approaches:
- Laparoscopic benefits include:
Complicated Hernias (Incarcerated/Strangulated)
- Emergency surgical repair is mandatory for strangulated hernias to prevent intestinal ischemia and increased morbidity/mortality 1, 2
- For clean surgical fields (no strangulation): prosthetic mesh repair is recommended 1
- For clean-contaminated fields: emergent prosthetic repair with synthetic mesh can be performed even with intestinal strangulation and/or concomitant need for bowel resection without gross enteric spillage 1
- For small defects (<3 cm) with bowel necrosis or peritonitis: primary repair is recommended 1
- When direct suture is not feasible, a biological mesh may be used 1
Special Techniques and Considerations
- Hernioscopy (laparoscopy through hernia sac) can be used to evaluate bowel viability, avoiding unnecessary laparotomy 1, 2
- Local anesthesia is recommended for emergency inguinal hernia repair in the absence of bowel gangrene 2
- General anesthesia is suggested over regional anesthesia in patients aged 65 and older as it might be associated with fewer complications 4
- Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair 4
Postoperative Care
- Patients should resume normal activities without restrictions as soon as they feel comfortable 4
- Monitor for potential complications including:
Common Pitfalls to Avoid
- Delaying repair of strangulated hernias can lead to bowel necrosis and increased morbidity/mortality 2, 5
- Overlooking occult inguinal hernias - these are symptomatic hernias without a visible bulge that can cause significant pain and may lead to increased opioid use if left untreated 6
- Ignoring femoral hernias, which have a higher risk of incarceration/strangulation, especially in women 4
