Abstract: To evaluate the diagnostic value and safety of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with biopsy-negative malignant gastrointestinal stricture, a retrospective analysis was performed on data of patients whose computed tomography scan showed gastrointestinal malignant tumor with complete lumen stricture and endoscopic biopsy results showed negative, who underwent EUS-FNA in the Second Affiliated Hospital of Soochow University from July 2016 to January 2020. Perioperative complications, technical success rate and accuracy of EUS-FNA were analyzed. Eleven cases included in the study, including 7 males and 4 females, with mean age of 60.3 years. There were 8 esophageal strictures and 3 rectal strictures. All patients successfully underwent EUS-FNA, and malignant tumor was found in 10 cases and no tumor cell was found in 1 case. No complications were reported. EUS-FNA is a safe and valuable approach to diagnosing biopsy-negative malignant gastrointestinal strictures.
