Evaluation of a New EUS Guided Biopsy Needle (SharkCore) Comparing to Standard EUS Needle (ProCore)
Evaluation of a New EUS Guided Biopsy Needle (SharkCore) Comparing to Standard EUS Needle (ProCore): A Prospective Randomized, Controlled Multicenter Study
Study Overview
Status
Detailed Description
Endoscopic ultrasound-guided fine needle aspiration and fine needle biopsy (EUS-FNA/FNB) have become mainstay diagnostic techniques for the diagnosis and evaluation of lesions of the pancreas, the upper gastrointestinal tract, as well as adjacent structures, including lymph nodes. Cytology specimens provided from FNA cannot fully characterize certain neoplasms such as lymphomas or mesenchymal tumors. Core biopsy specimens for histological examinations are needed to provide accurate diagnoses.
ProCore needles (ProCore, Wilson-Cook Medical Inc. Winston-Salem, NC) were designed to obtain histological and cytological samples. Studies comparing ProCore needles with standard FNA needles showed no significant difference in diagnostic accuracy, histological core tissue procurement or mean number of passes.
To overcome the above mentioned limitations (mainly suboptimal core tissue procurement rates), a new novel SharkCore needle (Beacon Endoscopic, Newton, MA, USA) has been designed and approved for clinical human use by the FDA.
The objective of the study is to compare the new EUS guided histology biopsy needle SharkCore to the currently used EUS histology needle, ProCore, for the histological diagnosis and evaluation of lesions.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: EUS-FNB with ProCore needle
General anesthesia or conscious sedation will be started and an upper endoscopic ultrasound will be inserted into the participants mouth and advanced to the site of the lesion.
The lesion will be punctured by the ProCore needle, then the stylet is completely removed, and negative suction pressure is applied using a 10 ml syringe for 30 seconds while the needle is stationary with the target.
Then, the needle is moved back and forth several times within the target, utilizing the fanning technique.
Finally, suction is released by closing the lock of the syringe and the needle is removed.
|
The use of the standard ProCore needle to acquire diagnostic tissue
This is the standard needle used currently to procure tissue from lesions under endoscopic ultrasound guidance
|
Active Comparator: EUS-FNB with SharkCore needle
The procedure will be done in the same manner with same endoscopic technique and method of tissue procurement.
The only difference will be using the SharkCore needle to acquire tissue.
|
The use of new SharkCore needle to acquire diagnostic tissue
This is the new FDA approved needle for tissue procurement under endoscopic ultrasound guidance.
