A neurolytic block is a type of nerve block injection that uses alcohol to damage nerves and achieve long-term pain relief in the torso region.

Neurolytic blocks are not used to treat pain in the arms, legs, hands, or feet. These differ from nerve block injections in that they destroy the nerve, instead of numbing it for temporary pain relief.

A neurolytic block is an outpatient procedure that takes up to one hour to complete. It is administered using X-ray images in real-time, much like a nerve block injection.

Neurolytic blocks are performed to relieve pain in patients diagnosed with various types of cancer, including:

• Colon cancer
• Gallbladder cancer
• Ovarian cancer
• Pancreatic cancer

Effectiveness of Neurolytic Blocks

Neurolytic blocks allow individuals diagnosed with end-stage cancer to lead a quality of life. This procedure is usually preferred over strong painkillers and narcotics, which can oftentimes cause over-sedation and disorientation.

Risks Associated with Neurolytic Blocks

Risks and complications associated with neurolytic blocks are uncommon, but may include:

• Bleeding and bruising at the site of injection
• Allergic reaction to the anesthetic
• Soreness at the injection site

That said, neurolytic block injections are often considered to be a long-term treatment option. However, sometimes pain can return after several months or several years.
