Utility of Intraoperative Cytology of Resection Margins in Biliary Tract and Pancreas Tumors

摘要

BackgroundIntraoperative diagnosis of resection margins in the biliary tract and pancreas tumors is important in deciding extent of resection; however, diagnosis based solely on frozen sections is sometimes difficult. Therefore, we investigated the usefulness of intraoperative cytology (IC) combined with frozen section (FS) histology. We present the results with a discussion of the value of this combination and its associated problems.
