Coeliac Plexus and Splanchnic Nerve Block for Cancer Pain

A coeliac plexus and splanchnic nerve block is a minimally invasive procedure that can be used to relieve severe abdominal pain caused by cancer. The coeliac plexus is a network of nerves located behind the stomach, and the splanchnic nerves are a group of nerves that supply the abdomen. By blocking these nerves, the procedure can help to interrupt the pain signals being sent to the brain. The procedure is typically performed under fluoroscopic guidance, which means that the doctor uses X-rays to guide the placement of a needle into the coeliac plexus and splanchnic nerves. Once the needle is in place, the doctor will inject a local anesthetic and/or a neurolytic agent, such as alcohol or phenol. The local anesthetic will provide immediate pain relief, while the neurolytic agent will destroy the nerve fibers, providing longer-term relief. The procedure is typically well-tolerated, and most patients experience significant pain relief within a few hours. Some patients may experience temporary side effects, such as nausea, vomiting, or lightheadedness. However, these side effects are usually mild and go away on their own within a few days. The procedure is typically performed as an outpatient procedure, and patients can usually go home the same day. However, some patients may need to stay overnight in the hospital for observation. The procedure can be repeated multiple times if needed. However, the effectiveness of the block may decrease over time as the nerve fibers grow back. The procedure is not right for everyone, and it is important to discuss the risks and benefits with your doctor before deciding if it is right for you.
