Endoscopic Ultrasound-guided Celiac Plexus Neurolysis in the Management of Pain in Abdominal Non-pancreatic Malignancies

September 23, 2014 updated by: Rajesh Keswani, Northwestern University

Endoscopic Ultrasound (EUS)-Guided Celiac Plexus Neurolysis (CPN) in the Management of Pain in Abdominal Non-pancreatic Malignancies

Celiac plexus neurolysis (CPN) has been performed for nearly 100 years to alleviate the abdominal pain associated with pancreatic malignancy and other conditions, and is usually undertaken at a late stage in the disease process, when analgesic options have been largely exhausted or have led to significant and often unacceptable side effects. Until recently, CPN was most commonly performed under radiographic guidance; however, in the last 10 years, CPN has been routinely performed under endoscopic ultrasound (EUS) guidance. Several case series have demonstrated the efficacy and safety of this technique when used to treat the pain associated with pancreatic malignancy and/or chronic pancreatitis. However, the efficacy of EUS-guided CPN in the treatment of pain related to non-pancreatic malignancies has yet to be described. The goal of this study is to assess the efficacy of EUS-guided CPN in the management of pain in patients with abdominal non-pancreatic malignancies. Our hypothesis is that EUS-guided CPN will provide adequate pain relief in these patients.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

  • Pain directly related to the primary malignant process, as determined by the referring oncologist
  • Pain determined to be refractory to standard medical therapy, or when the medical therapy is ineffective due to certain limitations (such as severe constipation), as determined by the referring oncologist
  • Willingness to undergo EUS-guided CPN
  • Age > 18 years

  • The patient will need to sign informed consent prior to inclusion in this study

Exclusion Criteria:

  • Unable or unwilling to undergo an EUS-guided CPN
  • Contraindication to anesthesia, as determine during the preoperative clearance process
  • Refractory coagulopathy (INR > 1.5) or thrombocytopenia (platelet count < 50,000), or aspirin and/or clopidogrel use within 7 days of procedure

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: EUS-CPN
Procedure: EUS-guided Celiac Plexus Neurolysis
All patients will receive anesthesia. The linear echo-endoscope will be advanced into the proximal stomach. It will be noted whether the tumor is seen in the celiac axis, if there is flow in the celiac artery, and if the celiac ganglia are seen. The celiac ganglia will be injected directly with 10cc of 0.25% bupivicaine followed by 10cc of 98% dehydrated alcohol. If the celiac ganglia cannot be identified, the posterior and anterior aspects of celiac artery take-off will be injected in a similar manner (twice the volume). Flow in the celiac axis will be confirmed. All injections will be performed with a standard EUS injection needle made especially for CPN . Prior to injection, aspiration will be performed through the needle to ensure that no blood is aspirated.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Difference between the mean pain score prior to and 1 month after the procedure, as determined by the Brief Pain Inventory (BPI)
Time Frame: 1 month
The BPI will be filled out just prior to and 1 month after the procedure to assess the difference in the mean pain score after the procedure
1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Difference in mean pain scores before and at 1 day after the procedure, 7 days after the procedure, 14 days after the procedure, and at 2 months after the procedure, as determined by the Brief Pain Inventory (BPI).
Time Frame: 2 months
The BPI will be filled out just prior to the procedure and after the procedure at the above intervals (up to 2 months) to assess the difference in the mean pain scores after the procedure.
2 months
Difference in the mean 'level of interference of pain with daily life' score, as determined by the Brief Pain Inventory (BPI). This score will be determined before and after the procedure, determined at the same intervals as mean pain scores.
Time Frame: 2 months
2 months
Narcotic use over a 24-hour period will be documented each time the Brief Pain Inventory (BPI) is completed
Time Frame: 2 months
Names, doses, and quantity of pain medications will be reported and converted to an equianalgesic dose (mg/day) of orally administered morphine. The difference in equianalgesic doses (mg/day) will be determined at the same intervals as mean pain scores.
2 months
