简要总结

The goal of this clinical trial is to evaluate the application of red cell lysis buffer (RCLB) versus conventional sample processing in endoscopic ultrasonography (EUS)-guided biopsy for solid pancreatic lesions. The main questions it aims to answer are:

whether the application of red cell lysis buffer improves histological tissue quality by decreasing blood contamination.

Participants with solid pancreatic lesions who needs histological diagnosis will receive EUS-guided biopsy. The obtained specimens will be processed by RCLB and conventional formalin solution.

Researchers will compare the blood contamination score of specimens in RCLB group with the conventional group see if the blood contamination can be improved.

结局指标

主要结局

Microscopic blood contamination assessments

时间窗: 2 months

Microscopic blood contamination is assessed by grading the percentage of the area of the blood cells in the entire ×40 field of view (score 3, \< 25 %; score 2, 25 % - 50%; score 1, \> 50 %; score 0, no material)

次要结局

  • Diagnostic sensitivity(2 months)
  • Tissue integrity assessments(2 months)
  • RNA and DNA adequancy(2 months)
  • Macroscopic blood contamination assessments(2 months)
  • Length of white core tissue(2 months)
  • Diagnostic accuracy(2 months)
  • Diagnostic specificity(2 months)
  • Immunohistochemical assessment(2 months)
