Clinical Trial to Evaluate the Endoscopic Ultrasound Guided Celiac Plexus Block for Treatment of Pain in Chronic Pancreatitis

Study Purpose

AIM: To compare pain relief in patients randomly assigned to endoscopic ultrasound-guided celiac ganglia block (EUS-CGB) vs.#46;standard endoscopic ultrasound-guided celiac plexus block (EUS-CPB). METHODS: This is a single-center, double-blind, randomized parallel-group study to assess the efficacy of EUS-CPB vs.#46; EUS-CGB in patients with painful chronic pancreatitis.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Other: EUS-celiac plexus block (EUS-CPB)

This is the standard technique. In this approach, the needle is passed through the body of the stomach adjacent the celiac artery into the retroperitoneal space in 1 or 2 passes. The injectate (bupivacaine or alcohol) is injected and spreads through the retroperitoneal space, effectively "bathing" all the ganglia.

Active Comparator: EUS-celiac ganglia block (EUS-CGB)

This is a more recent technique which has been often used. In this procedure, the needle is inserted under EUS guidance directly into as many ganglia as possible. For celiac ganglia <1cm in diameter, the solution is injected into the central point; for those ≥1 cm, a needle is advanced to the deepest point into the ganglia and solution is injected as the needle is slowly withdrawn. Injections are continued until an echogenic pattern is produced over the entire celiac ganglia.


Procedure: - EUS-celiac ganglia block (EUS-CGB)

The intervention technique of EUS-CGB is the realization of EUS-guided celiac block with injection of bupivacaine directly into the ganglia for patients with chronic pancreatitis.

Procedure: - EUS-celiac plexus block (EUS-CPB)

In the arm of EUS-CPB, the procedure is going to be performed with the standard EUS-guided celiac plexus block with injection of bupivacaine into the retroperitoneal space.
