Abstract

Image-guided Trucut biopsy is a well-established procedure. The length of the side notch in the stylet is the "cutting length," which entraps the tissue sample and contributes to the yield. The total distance by which the inner stylet protrudes from the outer cannula with the cutting notch open is the "throw length." It is inevitably longer than the cutting length does not add to the yield of the sample, but potentially to the complication of the procedure. The authors highlight the importance of knowing this distinction to minimize complications during the procedure.

摘要

影像引导下的粗针穿刺活检是一种成熟的操作。针芯侧槽的长度即“切割长度”，它夹住组织样本并影响取材成功率。在内置针芯的切割槽打开时，其从外套管伸出的总距离为“进针长度”。进针长度必然长于切割长度，虽不会增加样本取材成功率，但可能增加操作并发症。作者强调了解这一区别对于减少操作过程中并发症的重要性。
