Epinephrine Sprayed on the Papilla for the Prevention of Post-ERCP Pancreatitis

March 2, 2017 updated by: Anhui Provincial Hospital
Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) has been a well-recognized complication with significant morbidity and even mortality. A variety of possible mechanisms has been suggested in the occurrence of pancreatitis, but papillary edema caused by manipulations during cannulation or endoscopic treatment has received the most attention. The papillary edema may cause temporary outflow obstruction of pancreatic juice, and then increase ductal pressure, resulting in the occurrence of pancreatitis. Topical application of epinephrine on the papilla may reduce papillary edema. Moreover, it is reported that epinephrine sprayed on the papilla may be effective to prevent PEP. However, it is still unclear that epinephrine sprayed on the papilla can prevent acute pancreatitis after endoscopic retrograde cholangiopancreatography. We therefore designed a prospective randomized trial to determine whether epinephrine sprayed on the papilla prevent PEP after ERCP.

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.

Detailed Description

Between July 2016 and December 2017, 670 consecutive patients older than 18 years who are scheduled to undergo diagnostic or therapeutic ERCP at the Anhui Provincial Hospital will be recruited for the study. Patients were randomized using opaque, sealed envelopes containing random numbers assigning them to undergo a spray of epinephrine (epinephrine group) or saline (control group) on the major papilla. A two proportion equality test will be conducted to explore whether incidence rates are different. Descriptive statistics including number (N), mean, median, standard deviation, minimum and maximum, will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.

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 to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Males and females, age > 18 years.
  2. Normal amylase level before undergoing ERCP.
  3. Signed inform consent form and agreed to follow-up on time.

Exclusion Criteria:

  1. Pregnancy or history of allergy to epinephrine.

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
The prophylaxis effect of epinephrine sprayed on the papilla on post-ERCP pancreatitis
Time Frame: PEP occurence rate at 24 h after ERCP in two groups.

If the serum amylase of patients elevation and 3 times higher than the normal values after ERCP 24 hours in high risk patients, who also have clinical symptoms, without other acute abdominal diseases,such as gastrointestinal perforation,acute cholecystitia and acute cholangitis and etc. In this condition, it will be defined PEP(post-ERCP pancreatitis). Descriptive statistics will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.

Descriptive statistics will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.

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
Compare epinephrine group with control group on the incidence of hyperamylasemia/adverse events.
Time Frame: the incidence of hyperamylasemia/adverse events at 24 h after ERCP in two groups

Hyperamylasemia will be defined as the serum amylase 3 times more than the upper normal values, without clinical symptoms. During the study, any unexpected medical issue will be called adverse event.

Descriptive statistics will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.
