OBJECTIVES Risk stratification in Barrett's esophagus (BE) is challenging. We evaluated the ability of a panel of genetic markers to predict progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC). METHODS In this case-control study, we assessed a measure of genetic instability, the mutational load (ML), in predicting progression to(More)
BACKGROUND AND STUDY AIMS Limited data are available on the endoscopic ultrasound (EUS) and fine-needle aspiration (FNA) characteristics of cystic pancreatic neuroendocrine tumors (CPanNets). The aims of this study were to describe the EUS and FNA characteristics of pathologically confirmed CPanNets and to compare these characteristics with mucinous cysts(More)
BACKGROUND AND STUDY AIMS Intraductal papillary mucinous neoplasm (IPMN) consists of four epithelial subtypes. There are limited data on the endoscopic ultrasound (EUS) findings and/or cyst fluid analysis of the epithelial subtypes. The objective of this study was to determine whether there are differences in EUS and cyst fluid characteristics(More)
OBJECTIVE Intraductal papillary mucinous neoplasm (IPMN) consists of four epithelial subtypes that correlate with histological grades and risks for malignant transformation. mAb Das-1 is a monoclonal antibody against a colonic epithelial phenotype that is reactive to premalignant conditions of the upper GI tract. We sought to assess the ability of mAb Das-1(More)
BACKGROUND AND STUDY AIMS There have been concerns about peritoneal seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mucinous pancreatic cystic lesions. The aims of this study were to determine the frequency of postoperative peritoneal seeding in patients with intraductal papillary mucinous neoplasm (IPMN) who had undergone(More)
BACKGROUND The recognition of epithelial cells with high-grade atypia (HGA) in the cyst fluid of an intraductal papillary mucinous neoplasm (IPMN) identifies a cyst at high risk of invasive carcinoma. To the best of the authors' knowledge, the cytological features of HGA have not been systematically analyzed to define diagnostic criteria. METHODS Cell(More)
BACKGROUND Radiofrequency (RF) power is capable of ablation of neoplastic tissue arising from Barrett's esophagus. Endoscopic catheter bipolar RF ablation is a new technique for ablation of neoplastic tissue in the bile duct. OBJECTIVE To determine the effect of RF power on bile duct and solid organ histology. DESIGN Nonsurvival animal study. SETTING(More)
Studies show increased mortality with positive heparin-platelet factor-4 (H-PF4) antibodies, especially in hemodialysis patients. We aimed to compare mortality and thrombosis in hospitalized patients with positive, equivocal and negative H-PF4 antibody results. Information was collected on these patients using a multi-institutional retrospective electronic(More)
BACKGROUND AND AIMS Endobiliary radiofrequency ablation (RFA) has been used to treat occluded self-expandable metal stents (SEMSs). The aim of this study was to determine the characteristics of bipolar RFA in occluded SEMSs using both in vivo and in vitro models. METHODS For the in vivo study, uncovered SEMSs were deployed in the bile ducts of three pigs;(More)
BACKGROUND AND AIMS Application of endoscopic submucosal resection (ESMR) in the management of gastric subepithelial lesions (GSLs) less than 20 mm is gradually increasing because it allows diagnosis and treatment at the same operative session. In this study, we compare and evaluate the benefits of ESMR with an endoscopic cap band mucosectomy technique or(More)
