Lung cancer is one of the most frequent neoplasms in our environment, and represents the first cause of cancer related death in western countries. Diagnostic and therapeutic approach to these patients may be complicated, with endoscopic ultrasound guided fine needle aspiration (EUS-FNA), classically performed by gastroenterologists, playing a very important role. As this disease is not closely ...

BACKGROUND Obtaining tissue from a para-aortal lymph node or tumor is a challenge that currently requires invasive surgical procedures. Para-aortic lung tumors can be clearly visualized by EUS. Although the accessibility of lesions adjacent to the esophagus is well documented, the para-aortic region has never been systematically explored. OBJECTIVE To assess the feasibility, yield, and safety...

Our aim was to assess malignancy risk in adenomatoid nodules and suspicious follicular lesions of the thyroid obtained by fine needle aspiration (FNA) cytology. Retrospective research was performed of 276 patients who underwent thyroid surgery after preoperative ultrasound-guided FNA diagnosis of either adenomatoid nodule, cellular follicular lesion, "suspicious for follicular neoplasm" or foll...

PURPOSE Surgical resection as part of a multimodality approach in malignant pleural mesothelioma (MPM) has a high morbidity and mortality. Because mediastinal lymph node (MLN) metastases are a negative prognostic factor, preoperative staging is of paramount importance. Transesophageal endoscopic ultrasound with real-time guided fine needle aspiration (EUS-FNA) enables accurate MLN staging in lu...

CONTEXT We describe a case of cystic lymphangioma of the pancreas in which a preoperative tissue diagnosis was made with endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). CASE REPORT A 20-year-old female presented with upper abdominal pain of two months duration and was found to have a cystic lesion in the pancreatic tail. Radiological imaging could not determine the organ of ori...

Heterotopic pancreas (HP) is a relatively uncommon entity that is defined as pancreatic tissue without a true anatomical or vascular connection to the pancreas. HP does not cause symptoms in most cases but can occasionally produce various manifestations, including nausea, vomiting, abdominal pain, and even heterotopic pancreatitis. Here, we report an unusual case in which heterotopic pancreatit...

A 71-year-old man, who had received long-term oxygen therapy for respiratory failure caused by chronic obstructive pulmonary disease, had an enlarged mediastinal lymph node for one year. As his lung function was poor, we tried performing endobronchial ultrasound-guided transbronchial needle aspiration under non-invasive positive pressure ventilation for diagnosis but could not obtain sufficient...

CONTEXT Pancreatic splenosis is a benign condition which can mimic a pancreatic neoplasm. OBJECTIVE To describe the role of the endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic nodules suspicious for pancreatic splenosis. METHOD From 1997 to 2011, patients with pancreatic solid tumors suspicious for splenosis by computed tomography and/or magnetic resonance imagin...
