Fine-needle Biopsy Combined With Macroscopic On-site Evaluation for Diagnosis of Solid Pancreatic Lesions

The length of the tissue strips was judged using the specimen table and photographed for record. If the MVC of the first needle sample was ≥10mm, the tissue strip was placed into bottle A formalin for fixation. A second needle of tissue strip was pushed directly into the B-bottle formalin. If the first needle sample MVC was \< 10mm, the puncture was continued until the total length of sample MVC was ≥10mm, and all samples were placed into bottle A formalin.

Two needles were punctured and all tissue strips were placed into bottle A formalin.
