Description of intervention(s) / exposure
A Head to Head Comparative Pilot Trial of EUS Core Biopsy Needles: ProCore vs Shark Core and Acquire
All aspects of the study will be discussed with each subject during a phone interview or screening visit. An information sheet will be provided, and each subject will be given the opportunity to seek medical advice or to discuss the study with friends or family prior to involvement. Each volunteer will give written, informed consent, and the subjects will be free to withdraw from the study at any time.
Consenting patients will have the procedure under deep sedation (Propofol), administered by qualified anaesthetists. After the lesion is evaluated by EUS, the endoscopist will perform the tissue sampling using all needles consecutively. The order of the needle passes will be pre-determined in a randomized fashion using a computerized program. Each patient will have a single pass using the Shark Core, Acquire and ProCore needles (3 passes total).
All aspirated material will be placed in formalin (separate pots for each needle) to undergo direct histological processing (filtered through a microcassette, immersed in Ponceau S tinted neutral buffered formalin and processed as standard histological blocks).
All patients will be observed in recovery for a minimum 2 hours following the procedure for any complications. Trained cytologists and pathologists (who are blinded to the needle type used) will assess the final processed samples from each group in order to determine the diagnosis.
In order to objectively quantify the tissue acquired from each needle, the slides will be scanned using the NanoZoomer (Hamamatsu Phototonic, Japan) and high definition images stored electronically. Using the associated software (NDP.view2, Phototonic, Japan), the characteristics of the diagnostic tissue will be examined for the presence of tissue-core (defined as tissue showing preserved architectural integrity, in which the length of the core is at least twice of the nominal inner diameter of the used needle). The tissue-cores will then be objectively quantified by measuring the total core surface area, length and diameter. The quality of the specimen obtained was also assessed by measuring the surface area of diagnostic tissue in each core.

Outcomes
Primary outcome [1] 303016 0
To determine and compare the core tissue sizes acquired from the different needle groups. In order to objectively quantify the tissue acquired from each needle, the slides will be scanned using the NanoZoomer (Hamamatsu Phototonic, Japan) and high definition images stored electronically. Using the associated software (NDP.view2, Phototonic, Japan), the characteristics of the diagnostic tissue will be examined for the presence of tissue-core (defined as tissue showing preserved architectural integrity, in which the length of the core is at least twice of the nominal inner diameter of the used needle). The tissue-cores will then be objectively quantified by measuring the total core surface area, length and diameter.
Timepoint [1] 303016 0
This outcome is assessed within 2 days of the procedure.
Primary outcome [2] 303017 0
To determine and compare the sampling adequacy of tissue specimens acquired from each needle type. Trained cytologists and pathologists will assess the final processed samples from each group.
Adequacy is defined as adequate to make a diagnosis, tissue volume also determined by measuring surface area on slides.
Timepoint [2] 303017 0
This outcome is assessed within 2 days of the procedure.
Primary outcome [3] 303018 0
To determine and compare the histological qualities of tissue samples obtained from each needle. Trained cytologists and pathologists (who are blinded to the needle type used) will assess the final processed samples from each group. The qualities of each specimen obtained will be assessed by measuring the surface area of diagnostic tissue in each core (defined as tissue showing preserved architectural integrity, in which the length of the core is at least twice of the nominal inner diameter of the used needle).
Timepoint [3] 303018 0
This outcome is assessed within 2 days of the procedure.
Secondary outcome [1] 337704 0
To determine and compare the diagnostic accuracy of tissue quantities obtained (of pancreatic lesions) between the needle groups. Trained cytologists and pathologists (who are blinded to the needle type used) will assess the final processed samples from each group. Diagnostic accuracy with 1 pass using the 19G ProCore needle will be the reference standard.
Timepoint [1] 337704 0
This outcome is assessed within 2 days of the procedure.
Secondary outcome [2] 337705 0
To determine and compare the complications between the needles. This may be any bleeding, perforations etc. that may be associated with the needles. Given that the use of all devices have already been shown to be a safe method of acquiring pancreatic tissue specimens, this study poses no addition risks to the participants. This will be assessed via medical records and contact with the patient.
Timepoint [2] 337705 0
All patients will be observed in recovery for a minimum 2 hours following the procedure for any complications.
Secondary outcome [3] 337706 0
To assess and compare the technical failure between the different needle groups.
This is defined as the inability to insert needle into desired target. Assessed via medical records and with communication with the cytologists and pathologists.
Timepoint [3] 337706 0
All patients will be observed in recovery for a minimum 2 hours following the procedure for any complications. Differences between groups to be compared once sufficient patients have been diagnosed, approximately 1 year within commencement of study.
Secondary outcome [4] 337707 0
To determine the timing of the procedures between the different needles. This outcome is assessed by monitoring and recording time taken during the procedure.
Timepoint [4] 337707 0
Procedure time determined during the procedure. Differences between groups to be compared once sufficient patients have been diagnosed, approximately 1 year within commencement of study.

Summary
Brief summary
The primary purpose of this trial is to compare the efficacy of three types of core biopsy needles used for Endoscopic Ultrasound-Guided (EUS) fine needle biopsy.

Who is it for?
You may be eligible to enroll in this trial if you are aged 18 years old or older and require endoscopic ultrasound and tissue sampling of solid lesions in the pancreas, which are suitable for EUS fine needle aspiration.

Study details
All participants enrolled in this trial will have tissue sampling performed using three different biopsy devices: the ProCore, the Shark Core and Acquire devices. The order in which each device is used will be randomly allocated (by chance). Only a single pass (i.e. a single attempt at sampling) will be completed for each device. The tissue obtained using each device will be stored and analysed by cytologists and pathologists to determine the diagnosis and adequacy of samples obtained using each device.

It is hoped that the findings from this trial will provide information on which of the three devices provides the most sufficient samples for analysis and diagnosis of pancreatic lesions.
