Study Overview

Brief Summary

The goal of this clinical trial is to compare the diagnostic efficacy, core tissue acquisition ability, number of punctures and puncture time of macroscopic on-site evaluation (MOSE) and two punctures alone in Endoscopic ultrasound guided fine-needle biopsy (EUS-FNB) for solid pancreatic lesions. The main questions it aims to answer is: whether the diagnostic accuracy of EUS-FNB performed with two needle passes is not inferior to that of MOSE.

Participants with solid pancreatic lesions who needs histological diagnosis will receive EUS-FNB using 22G Franseen.

In Group 1, the macroscopically visible core (MVC) of the specimen was assessed. If the MVC of the sample obtained from the first needle was ≥10mm, the tissue strip was placed in Bottle A and fixed with formalin. A second needle was then used to obtain another tissue strip, which was directly placed into Bottle B containing formalin. However, if the MVC of the first needle sample was < 10mm, the puncture procedure was continued until the cumulative length of sample's MVC was ≥10mm, and all the sample collected during this process were placed into Bottle A and fixed with formalin. In Group 2, two needles were used to obtain tissue strips, and all the tissue strips were placed into Bottle A formalin.

Researchers will compare the diagnostic efficacy, core tissue acquisition ability, number of punctures and puncture time between the MOSE technique and two-needle puncture method.

Arms & Interventions

MOSE group

Experimental

Patients assigned to this group will receive EUS-FNB as routine. The obtained tissue will be evaluated by Macroscopic On-site Evaluation

Intervention: MOSE application (Procedure)

Non-mose group

Active Comparator

Patients assigned to this group will receive EUS-FNB as routine. Two needles were punctured and all tissue strips were placed into bottle A formalin.

Intervention: Conventional processing (Procedure)

Outcomes

Primary Outcomes

Diagnostic accuracy

Time Frame: 6 months

Diagnostic accuracy was calculated as the proportion of true positive and true negative in all evaluated cases.

Secondary Outcomes

  • Median puncture number(2 months)
  • Tissue adequacy(2 months)
  • Puncture time(2 months)
