Endoscopic ultrasound (EUS) represents an advance in the diagnosis and staging of several diseases. EUS-guided fine-needle aspiration is useful, but technically demanding, and can be associated with complications. Elastography emerges…
Endoscopic ultrasound (EUS)-guided needle placement of small radiopaque particles paves the way for EUS-guided fiducial markers and brachytherapy. Stereotactic body radiation therapy relies on image-guided radiation therapy (IGRT), permitting escalation…
The development of linear-array endoscopic ultrasonography (EUS), with its real-time guidance of needle advancement, changed EUS from a diagnostic procedure to an interventional procedure. EUS-guided fine-needle injection (EUS-FNI) is an…
Pancreatic cystic neoplasms represent a wide spectrum of invariably benign to precancerous and malignant tumors. Endoscopic ultrasound-guided pancreatic cyst ablation with ethanol and/or paclitaxel offers a nonoperative treatment for patients…
Abdominal and pelvic abscesses have traditionally been drained by percutaneous techniques or surgery. While surgical drainage is associated with considerable morbidity and mortality, percutaneous techniques are associated with the need…
To date, percutaneous transhepatic biliary drainage (PTBD) has been considered as the usual biliary access after failed endoscopic retrograde cholangiopancreatography (ERCP). Since endoscopic ultrasonography (EUS)-guided bile duct puncture was first…
The success rate of deep biliary cannulation is high but still not perfect in endoscopic retrograde cholangiopancreatography (ERCP), even with aggressive techniques. With the development of linear-array echoendoscopes, the endoscopic…
This article reviews different techniques available for diagnosis and staging of patients with non-small cell lung cancer (NSCLC). The advantages and disadvantages of each staging method are highlighted. The role…
Subepithelial lesions are frequently discovered during routine endoscopic examinations. These lesions represent a wide spectrum of heterogeneous benign to malignant conditions. Most of these lesions are asymptomatic. There is no…
The diagnosis and management of pancreatic cystic lesions remains a challenging area in gastroenterology. Differentiating benign from premalignant or premalignant from malignant cysts is complicated by the large overlap in…
