Efficacy of endoscopic ultrasound-guided fine needle aspiration in the diagnosis of metastases to the pancreas: an analysis of 11 cases / 中华消化内镜杂志

ABSTRACT

To evaluate the efficacy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for patients with metastases to the pancreas.Data on patients with pancreatic lesions who underwent EUS-FNA and confirmed as having metastases to the pancreas at the Endoscopy Center of Zhongshan Hospital, Fudan University from January 2015 to November 2020 were retrospectively analyzed.Characteristics of patients, EUS performance, pathological results, and follow-up were reviewed and analyzed. A total of 11 patients were diagnosed of metastasis to pancreas by EUS-FNA.The primary tumor mainly came from kidney (4/11) and lung (4/11), and the rest from colon (1/11), breast (1/11) and bladder (1/11), respectively. EUS performance of metastases to the pancreas mostly presented homogeneous hypoecho (10/11)with unclear margin (6/11). Enlarged lymphnodes were noticed in nearly half of the patients (5/11). The time span from detection of primary tumor to metastases ranged from 6 days to 27 years. EUS-FNA is effective in the diagnosis of metastases to the pancreas.
