EUS-CPN With and Without Bupivacaine

Pancreatic Cancer

Endoscopic ultrasound (EUS) allows EUS-guided trans gastric injection of absolute alcohol around the base of the celiac plexus (celiac plexus neurolysis (EUS-CPN)), to help alleviate pain associated with pancreatic cancer.

It is standard procedure to inject bupivacaine immediately before injecting absolute alcohol, to theoretically prevent pain that may occur during and after the procedure. However, there are no data showing whether bupivacaine injection has any real influence on intra-procedural, immediate post-procedural, or long-term pain control. The injection of bupivacaine before the alcohol may have no effect, a synergistic effect, or an antagonistic effect, by diluting the alcohol, and reducing its neurolytic capacity. Inadvertent intravascular injection of bupivacaine may also cause irreversible cardiac arrhythmias and death.

The investigators therefore propose a randomized clinical trial to determine whether the exclusion of bupivacaine during EUS-guided CPN improves outcomes, or not.
