Histopathological evaluation of needle tract seeding caused by EUS-fine-needle biopsy based on resected specimens from patients with solid pancreatic masses: An analysis of 73 consecutive cases

摘要

EUS-guided fine-needle biopsy (EUS-FNB) is considered a safe and useful method for preoperative diagnosis of resectable solid pancreatic masses. However, needle tract seeding (NTS) after EUS-FNB has recently been reported, which may affect long-term outcome. The aim of this study was to evaluate NTS after EUS-FNB.
