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

This is a single-blind, randomized, controlled trial. One thousand two hundred and twenty four patients with solid pancreatic lesions referred for EUS guided fine needle biopsy will be randomly assigned to 4 arms. For arm A1 which will be used with 22G EUS Procore fine needle biopsy device, the pass sequence is slow pull(SP)-modified wet suction technique(MWST)-slow pull(SP)-modified wet suction technique(MWST). For arm A2 with 22G EUS Procore fine needle biopsy device, the pass sequence is MWST-SP-MWST-SP. For arm B1 with 20G EUS Procore fine needle biopsy device, the pass sequence is SP-MWST-SP-MWST. For arm B2 with 20G EUS Procore fine needle biopsy device, the pass sequence is MWST-SP-MWST-SP. All procedures will be performed by experienced echoendoscopists, and the patients and assessors (cytologists and pathologists) will be blinded during the entire study. The primary outcome measure is the diagnosis yield. Secondary outcome measures are specimen quality.

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.

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 diagnostic yields
Time Frame: up to 15 months
The investigators' primary outcome measure is to compare the diagnostic yields of 22G FNB and 20G FNB to the solid pancreatic lesions.
up to 15 months

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
the tissue integrity
Time Frame: up to 15 months
The investigators' secondary outcome measure is to assess the tissue size under a light microscope to compare the tissue obtained by 22G FNB and 20G FNB with Slow-pull or modified wet suction technique.
up to 15 months
