Abstract
- <bold>Background and Study Aims: </bold>No previous studies have evaluated the ability of endoscopic ultrasonography to describe the anatomic location of lymph nodes on the basis of a node-to-node comparison. The aim of this study was to assess the feasibility and safety of a new endoscopic ultrasound (EUS)-guided fine-needle technique for marking lymph nodes. <bold>Patients and Methods: </bold>Twenty-five patients with suspected or confirmed malignancies of the upper gastrointestinal tract were prospectively included. EUS-guided fine-needle marking (EUS-FNM) was performed with a silver pin with a diameter that allowed it to fit into a 19-gauge needle. The position of the pin was verified by EUS. End points were the ability to identify and isolate the marked lymph node during surgery and a comparison between the location of the pin as suggested by EUS and the actual location found in the resected specimen. <bold>Results: </bold>Twenty-three lymph nodes were marked. Nineteen intended surgical isolations were performed. The lymph nodes were isolated in the resection specimens in 18 patients (95 %). In 2 out of 20 cases the pin was not localized by laparoscopic ultrasonography. In 89 % of the cases the marked lymph node was in the same location as described by EUS. One pin (5 %) was not retrieved. In three cases, a small hematoma was observed. There was no sign of long-term complications. <bold>Conclusion: </bold>EUS-FNM with a silver pin in lymph nodes is feasible and safe. EUS-FNM seems to be a suitable tool for evaluating lymph nodes on the basis of a node-to-node comparison. [ABSTRACT FROM AUTHOR]
