What is it used for, and what diseases or chronic conditions does it treat?
Gangliolysis is a minimally invasive medical procedure that involves selectively blocking specific nerve ganglia to interrupt the transmission of chronic pain signals. This technique uses neurolytic agents—such as absolute alcohol or phenol—that are precisely injected into the nerve ganglia responsible for transmitting pain, resulting in a temporary or permanent interruption of nerve conduction.
The procedure is performed under advanced imaging guidance, such as fluoroscopy or computed tomography, to ensure accurate localization of the target ganglion. Once the ganglion is identified, a specialized needle is inserted and the neurolytic agent is administered in controlled doses, selectively destroying the pain-transmitting fibers without affecting other essential nerve functions.

What is it used for and what diseases or chronic pains does it treat?
Gangliolysis is indicated for the treatment of severe chronic pain conditions that do not respond adequately to conservative treatments:
Chronic abdominal pain due to pancreatic cancer through celiac plexus block
Chronic pelvic pain through superior hypogastric plexus block
Drug-resistant trigeminal neuralgia through gangliolysis of the Gasserian ganglion
Atypical facial pain and other cranial neuralgias
Oncologic visceral pain of abdominal or pelvic origin
Complex regional pain syndrome of the extremities
Neuropathic pain originating in specific sympathetic ganglia
Cluster headaches refractory to conventional treatments
Chronic low back pain through blockade of the lumbar sympathetic chain
This procedure is reserved for cases in which pain severely impacts quality of life and other therapeutic approaches have proven insufficient.
Benefits compared to other treatments
Gangliolysis offers several key advantages in the management of refractory chronic pain:
Selective precision: Enables targeted blockade of individual nerve ganglia while minimizing impact on unrelated nerve functions.
Long-lasting effect: Relief can last from several months to years, providing sustained pain reduction..
Alternative to major surgery: Avoids the risks and recovery time associated with more invasive surgical procedures.
Effective in refractory cases: Offers relief when other treatments—including high-dose opioids—have failed.
Significant functional improvement: Helps patients regain daily activities previously limited by pain.
Reduction of pharmacological dependence: Decreases the need for strong analgesics and minimizes associated side effects.
Outpatient procedure: Performed with local anesthesia, allowing patients to return home the same day.
Cost-effectiveness: A single procedure can replace the need for long-term, high-cost treatments.
Improved quality of life: Restores functionality and enhances both psychological and social well-being.
Gangliolysis represents an advanced therapeutic option for achieving effective pain control in carefully selected patients.
