EUS-CPN With and Without Bupivacaine

Under conscious sedation, an echoendoscope is advanced into the stomach, just distal to the gastro-esophageal junction. The region of the celiac plexus is identified around the takeoff of the celiac artery from the aorta. Then, under real-time ultrasound guidance, a 19g needle is used to inject a neurolytic agent such as absolute alcohol around the base of the celiac artery.
