Endoscopic Ultrasound-guided Fine Needle Biopsy With 25-gauge Biopsy Needles for Solid Pancreatic Masses

March 27, 2019 updated by: Yonsei University
For 12 months after approvement by the University of Yonsei institutional review board, of the 59 patients older than 20 years referred to our medical center for EUS-FNA or FNB, all consecutive pancreatic lesions were evaluated for inclusion in our prospective study. The inclusion criteria for this study were the following: diagnosed or suspected solid pancreatic masses according to clinical evaluation and imaging studies with need of histologic tissue confirmation by EUS-FNA or EUS-FNB. The exclusion criteria were the following: cystic pancreatic lesions, patients haemodynamically unstable or with severe coagulopathy (international normalized ratio [INR] > 1.5 or platelet count < 50,000 cells/cubic millimeter [cmm3]), patients unable to suspend anticoagulant/anti-platelet therapy, pregnancy, inability or refusal to give informed consent, and refusal to participate in the study. Patients undergoing anticoagulant or anti- platelet therapy for non-critical problems discontinued treatment at least 5 days before the endoscopic procedure. Written informed consent was obtained from all patients for the procedures performed and participation in the study, and the study protocol was approved by the University of Yonsei institutional review board. All patients were underwent the procedure under conscious sedation with propofol and midazolam according to the current guidelines.8 After procedure, the patients were monitored for at least six hours in order to immediately detect post-procedural complications and were followed for up to 7 days in order to detect late complications.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access 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.

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

20 years and older (Adult, Older Adult)

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
accessing the rate for procurement of the histologic core
Time Frame: up to 5 minuites after endoscopic ultrasound-guided fine needle biopsy
The tissue samples were immediately fixed in formalin. The histologic cassette was processed, embedded in paraffin, and then prepared in hematoxylin and eosin to be evaluated by one pathologist (K.H.K) for the presence of a histologic core. If the histologic core was present, the specimen was graded as optimal or suboptimal. Optimal specimens were those in which the procured material enabled satisfactory assessment of histologic architecture that either did not change the original diagnosis or yielded additional findings. Suboptimal specimens were those in which the quality of the histologic core was unsatisfactory for assessment of histologic architecture. When required, immunohistochemical or special staining was performed for differentiation of morphologically challenging lesions.10
up to 5 minuites after endoscopic ultrasound-guided fine needle biopsy

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 percentage of cases in which pathologists classified the sample quality as optimal for histological evaluation of 25-gauge biopsy needle
Time Frame: up to 5 minuites after after endoscopic ultrasound-guided fine needle biopsy
The tissue samples were immediately fixed in formalin. The histologic cassette was processed, embedded in paraffin, and then prepared in hematoxylin and eosin to be evaluated by one pathologist (K.H.K) for the presence of a histologic core. If the histologic core was present, the specimen was graded as optimal or suboptimal. Optimal specimens were those in which the procured material enabled satisfactory assessment of histologic architecture that either did not change the original diagnosis or yielded additional findings. Suboptimal specimens were those in which the quality of the histologic core was unsatisfactory for assessment of histologic architecture.
