We are doing this study to get more information on this type of lung biopsy. Our hospital does more cryobiopsies than anyone else in the United States. This type of biopsy has become standard in our practice. We want to answer two questions: 1) How many biopsies are necessary? 2) Is there a difference between a small biopsy tool and a large biopsy tool? So far we have been getting 5 biopsy pieces to make sure that we get enough material, however we do not know if getting fewer biopsies (3) would be just as good. We also don’t know if using a small biopsy tool is different from using a large biopsy tool. So far we have used both interchangeably. From our experience we believe that both tools are probably the same, but we want to compare them to know for sure. The device we use to take these biopsies is called ERBEKRYO, and uses liquid nitrogen to freeze the tip of a biopsy tool. We put the tool into the lung and freeze a small piece of lung tissue. The lung tissue around the tip of the tool gets stuck and comes out easily. That’s how we get pieces of lung tissue to analyze under the microscope.
