BACKGROUND The management strategies for Barrett's esophagus (BE) that contains high-grade dysplasia (HGD) include intensive endoscopic surveillance, photodynamic therapy, thermal ablation, EMR, and esophagectomy. OBJECTIVE To assess the safety and effectiveness of endoscopic circumferential balloon-based ablation by using radiofrequency energy for(More)
OBJECTIVE In our previous randomized trial, we suggested a possible role for endoscopic ultrasound (EUS) guided celiac plexus block in the treatment of abdominal pain associated with chronic pancreatitis. The purpose of this study was to evaluate our prospective experience with EUS-guided celiac plexus block for controlling pain attributed to chronic(More)
BACKGROUND Current methods for staging pancreatic cancer can be inaccurate, invasive, and expensive. Endoscopic ultrasound (EUS) is reported to be highly accurate for local staging of gastrointestinal tumors including pancreatic cancer. The aim of this study was to assess the utility of EUS and CT for staging pancreatic cancer by comparing staging(More)
BACKGROUND/GOALS Endoscopic ultrasound (EUS)-guided celiac plexus block (CPB) and celiac plexus neurolysis (CPN) have become important interventions in the management of pain due to chronic pancreatitis and pancreatic cancer. However, only a few well-structured studies have been performed to evaluate their efficacy. Given limited data, their use remains(More)
BACKGROUND In many institutions, computed tomography (CT)-guided percutaneous fine-needle aspiration (FNA) has become the procedure of choice for biopsies of pancreatic mass lesions. This method of biopsy and others, such as endoscopic retrograde cholangiopancreatography (ERCP) cytology, are problematic because of a substantial false-negative rate. (More)
BACKGROUND Endoscopic ultrasound (EUS) accurately stages gastrointestinal malignancies but is less able to differentiate between neoplastic and inflammatory processes. EUS-guided fine-needle aspiration (EUS FNA) has been reported useful for obtaining a diagnosis in suspected gastrointestinal lesions. We report our entire experience with EUS FNA using both(More)
BACKGROUND Metastatic lesions of the pancreas are a rare but important cause of focal pancreatic lesions. The purpose of this study is to describe the EUS features, cytologic diagnoses, and clinical impact of a cohort of patients with pancreatic metastases diagnosed by EUS-guided FNA (EUS-FNA). METHODS Over a 6-year period, in a retrospective, multicenter(More)
OBJECTIVE Computed tomography (CT)-guided celiac plexus neurolysis has been used for controlling the chronic abdominal pain associated with intra-abdominal malignancy and chronic pancreatitis. Endoscopic ultrasound (EUS)-guided celiac plexus neurolysis has been reported to have some success in controlling pain from pancreatic cancer. The aim of this study(More)
Esophageal stents are important tools for palliative treatment of inoperable esophageal malignancies. With the development of multiple self-expandable stents, there are now several therapeutic options for managing benign and malignant esophageal diseases. This paper discusses the various types of esophageal stents currently available, indications for their(More)
