Endoscopic Ultrasound in the Diagnosis and Staging of Pancreatic Cancer
نویسندگان
چکیده
Endoscopic ultrasound was developed in the early 1980s to overcome the limitations of transabdominal ultrasound in imaging the gastrointestinal wall and retroperitoneum.[1] The ultrasound transducer (positioned at the endoscope tip) is applied directly against the duodenal or gastric wall. This enhances the image quality by minimizing intervening adipose tissue and air that must be traversed by the ultrasound. The proximity of the transducer to the target tissue allows the use of higher frequency ultrasound and leads to greater image resolution. Accordingly, the use of endoscopic ultrasound has become routine for diagnosing and staging pancreatic and other gastrointestinal tumors.[2-4]

Conventional radiologic imaging (abdominal ultrasound, computer tomography) used in the differential diagnosis of post-hepatic jaundice can frequently provide inaccurate diagnosis. Inflammatory lesions may mimic neoplastic processes and malignancy may be accompanied by perifocal inflammation resulting in histological misdiagnosis. Furthermore, chronic and autoimmune pancreatitis are associated ...

Endoscopic ultrasound-guided fine needle aspiration-biopsy is a safe and effective technique in diagnosing and staging of pancreatic ductal adenocarcinoma. However its predictive negative value does not exceed 50% to 60%. Unfortunately, the majority of pancreatic cancer patients have a metastatic and/or a locally advanced disease (i.e., not eligible for curative resection) which explains the li...

Endoscopic ultrasound (EUS) evolved as the diagnostic test of choice evaluating suspected pancreatic tumors. Coupled with fine needle aspiration (FNA), EUS provides high accuracy for the diagnosis and staging of pancreatic cancer. Novel EUS based techniques have emerged as a safe minimally invasive alternative to the surgical or radiological approaches. By allowing better pain control, deliveri...
متن کاملEndoscopic Ultrasound in the Diagnosis and Staging of Pancreatic Cancer
Pancreatic cancer is one of the digestive cancers with the poorest prognosis, so an early and correct diagnosis is of utmost importance. With the development of new therapeutic options an accurate staging is essential. Endoscopic ultrasonography (EUS) has a major role in all stages of the management of these patients. EUS has a high accuracy in the diagnosis of pancreatic adenocarcinoma and the...
