When doctors need to biopsy a solid mass in the pancreas, getting enough high-quality tissue is vital for an accurate diagnosis. This procedure can be difficult because of the location of the organ. Researchers looked at data from 412 patients to see if using a specific needle design, called Reverse-bevel ProCore fine needle biopsy (FNB), changed how well doctors could identify cancer compared to the standard fine needle aspiration (FNA) method.
The results showed that both methods provided an equal diagnostic yield. This means the ability to find out what the tissue actually is did not change based on which needle was used. However, the ProCore needle required fewer passes into the body to get a usable sample. Other factors like sensitivity and how much of the sample was adequate were also similar between the two methods.
While the new needle might make the procedure faster or easier for the technician by requiring fewer passes, it is important to note that the evidence for choosing one specific needle over another is currently low to very low. Because the data is limited, patients and doctors should discuss which method is best based on their specific needs.
