Inguinodynia is a medical condition characterized by chronic pain in the groin region. It is often associated with inguinal hernia repair surgery, although it can occur due to other causes as well. The term "inguinodynia" is derived from "inguino-" meaning groin and "-dynia" meaning pain.

Etiology

Inguinodynia is most commonly seen as a complication following inguinal hernia repair. The pain is typically neuropathic in nature, resulting from nerve injury or entrapment during the surgical procedure. The nerves most commonly involved include the ilioinguinal nerve, iliohypogastric nerve, and the genitofemoral nerve.

Pathophysiology

The pathophysiology of inguinodynia involves nerve damage or irritation. During hernia repair, nerves in the groin area may be inadvertently injured, leading to chronic pain. This can occur due to:

• Direct nerve injury during dissection.
• Nerve entrapment in scar tissue.
• Compression by mesh used in hernia repair.

Clinical Presentation

Patients with inguinodynia typically present with:

• Persistent groin pain lasting more than three months post-surgery.
• Pain that may be sharp, burning, or aching in nature.
• Pain that may radiate to the inner thigh or scrotum.

Diagnosis

Diagnosis of inguinodynia is primarily clinical, based on the patient's history and physical examination. Imaging studies are generally not helpful but may be used to rule out other causes of groin pain. Diagnostic nerve blocks can be used to confirm the involvement of specific nerves.

Management

Management of inguinodynia can be challenging and may include:

• Pharmacological therapy: Use of analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and neuropathic pain medications such as gabapentin or pregabalin.
• Nerve blocks: Local anesthetic injections to provide temporary relief.
• Surgical intervention: In cases where conservative management fails, surgical options such as neurectomy (removal of the affected nerve) may be considered.

Prognosis

The prognosis for inguinodynia varies. Some patients experience significant relief with conservative measures, while others may require surgical intervention. Early recognition and management are crucial to improving outcomes.

Prevention

Preventive strategies during hernia repair include:

• Careful dissection to avoid nerve injury.
• Identification and preservation of nerves when possible.
• Use of minimally invasive techniques to reduce tissue trauma.
