Key Points • Communication between the endosonographer and the cytopathologist is the key to a successful endoscopic ultrasonography-guided fine-needle aspiration (EUS FNA) service. • A cytopathology service should be involved…
Key Points • Endoscopic ultrasonography-guided biliary drainage (EUS-BD) is gaining popularity as the procedure of choice over percutaneous methods in patients with failed biliary cannulation in endoscopic retrograde cholangiopancreatography. •…
Key Points • Endoscopic ultrasonography (EUS)-guided ablative therapy consists of the injection of cytotoxic agents into cystic cavities or ganglia to eliminate premalignant epithelium or to produce neurolysis. • Celiac…
Key Points • Recognition of different types of pancreatic fluid collections is crucial for appropriate management. • Endoscopic-ultrasonography (EUS)-guided drainage is the treatment of choice in the management of pancreatic…
Key Points • Anal endosonography (AES) is simple to perform and visualizes the anal sphincter complex—notably the external and internal anal sphincters. • AES is able to image sphincter tears…
Key Points • An anastomosis can be established between the stomach and the jejunum under the guidance of endoscopic ultrasonography (EUS) in patients with gastric outlet obstruction. A lumen-apposing metal…
Key Points • The needle should be kept in the visual plane at all times. • Excessive force should never be used to pass the needle sheath past an acute…
Key Points • The differential diagnosis of pancreatic cystic lesions is wide: the majority of these lesions are benign, but detection of mucinous neoplasms (IPMN and MCN) is important because…
Key Points • Although endoscopic ultrasound-guided fine-needle aspiration (EUS FNA) is very accurate, it cannot fully characterize certain neoplasms, and lack of cytology expertise may result in a limited perceived…
Key Points • Endoscopic ultrasonography (EUS) can accurately differentiate a mural lesion from extrinsic compression against the gut wall. • Determination of the cause of an intramural lesion is based…
