AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with a pancreatic mass that looks like cancer, or proven pancreatic cancer, who have pain that may come from the mass and cannot have surgery.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Malignant-looking pancreatic mass or proven pancreatic cancer in the genu, body or tail of the pancreas, with no possibility of surgery. The celiac axis must be reachable for treatment on both sides.
Main reasons for not taking part
- Allergy to bupivacaine
- Surgery is possible for the mass
- Pain with an obvious other source

A Randomized Controlled Trial of Endoscopic Ultrasound Guided Celiac Plexus Neurolysis (EUS-CPN) With and Without Bupivacaine
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.
