“…7 The fi rst EUS device for gastrointestinal use was developed specifi cally to image the pancreas. 8 These early studies focused on the technical feasibility of EUS to detect small pancreatic carcinomas in pancreatic images. 9 Raimondo et al 10 have attempted to diagnose early chronic pancreatitis using EUS, but a gold standard procedure has not yet been established so a diagnosis by EUS alone is insuffi cient.…”

“…Endoscopic ultrasonography (EUS) was introduced to clinical medicine for more than 30 years ago [1][2][3] and has contributed to the diagnosis and management of pancreatic tumors. EUS scanning system can be divided into two categories: radial and linear, with both mechanical and electronic formats available in each.…”

Endoscopic ultrasound (EUS) is a very useful modality for the diagnosis and staging of pancreatic masses. With the advent of EUS-guided fine-needle aspiration technology, this modality has made a tremendous leap from imaging modality to histologic diagnosis and therapeutic intervention. EUS offers high-resolution images of and unparalleled access to the pancreas. After locating the tip of the echoendoscope in the duodenum or stomach, several drugs or local treatment modalities can be delivered directly into the pancreas. EUS-guided ethanol lavage with/without paclitaxel injection has been tested for the treatment of cystic tumors of the pancreas, with complete resolution of cystic tumor being observed in up to 70-80% of patients. Ethanol injection is also performed for the management of solid neuroendocrine tumors of the pancreas. Various type of EUS-guided injection have also been investigated for the treatment of pancreatic cancer. An activated allogenic mixed lymphocyte culture (Cytoimplant) was injected in patients with advanced pancreatic cancer. A replication-deficient adenovirus vector carrying the tumor necrosis factor-alpha gene was also delivered intratumorally by EUS. ONYX-015 is an oncolytic attenuated adenovirus that exhibits replication preferentially in malignant cells, causing cell death, and this has also been injected into pancreatic cancers under EUS guidance. EUS-guided local ablation therapies such as radiofrequency ablation, photodynamic therapy, and brachytherapy are also under investigation. EUS-guided fine-needle injection for various solid or cystic lesions is a rapidly expanding field. This article reviews the various applications of EUS for the treatment of pancreatic tumors.

“…Endoscopic ultrasound (EUS) was developed in 1980s to overcome the limitations of transabdominal ultrasound for imaging the pancreas. 1,2 Since it was developed its clinical applications have broadened to include assessing gastrointestinal (GI) submucosal lesions, the staging of gastrointestinal and lung cancers, detecting bile duct stones and evaluating pancreatic diseases. 3,4 It is the only imaging method that allows visualization of different gut wall layers in fine detail.…”
