BACKGROUND Ground-glass opacity (GGO) lesions are difficult to diagnose by transbronchial biopsy (TBB). OBJECTIVES We attempted to diagnose solitary peripheral GGO predominant-type lesions by TBB using endobronchial ultrasonography with a guide sheath (EBUS-GS) under X-ray fluoroscopic guidance, and to evaluate several factors associated with diagnostic yield. METHODS The medical records of...

Background. Endoscopic ultrasound- (EUS-) guided drainage is generally performed under fluoroscopic guidance. However, improvements in endoscopic and EUS techniques and experience have led to questions regarding the usefulness of fluoroscopy. This study aimed to retrospectively evaluate the safety and efficacy of EUS-guided drainage of extraluminal complicated cysts without fluoroscopic guidanc...

Introduction: Tracheal stents are deployed to attenuate intrinsic or extrinsic airway compression. They remain the gold standard for management of airway stenosis, especially when surgical resection is contraindicated. This study aimed to determine whether stent placement, by either fluoroscopic guidance or rigid bronchoscopy, resulted in improved procedural outcomes. Methods: We compared two t...

A 41-year-old male with situs inversus totalis had paroxysmal supraventricular tachycardia. On electrophysiology study, the mechanism of the tachycardia was determined as slow/fast atrioventricular nodal reentrant tachycardia and slow pathway was successfully performed under fluoroscopic guidance.

Background and Objective: Computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. This study aims to compare and contrast the success of biopsy under guide...

A 65-year old man with advanced pancreatic cancer with a combination of malignant biliary obstruction and gastric outlet obstruction was referred to our hospital. Given the presence of periampullary cancerous lesions, the endoscopic placement of a duodenal stent and endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) were performed simultaneously, using a single convex-array echoendosc...
