BACKGROUND Endoscopic mucosal resection (EMR) has been proposed as a primary method of managing patients with dysplasia- or mucosal-based cancers of the esophagus. OBJECTIVES To evaluate the use of EMR for the treatment of Barrett's esophagus with dysplasia or early adenocarcinoma, assessing efficacy, complication rates and long-term outcomes. METHODS(More)
OBJECTIVES Endoscopic ultrasound (EUS)-guided celiac plexus block/neurolysis (CPB/N) can be performed by injecting at the base (central) or on either side (bilateral) of the celiac axis. Central CPB/N is easier and possibly safer. Bilateral CPB/N is more difficult but may be more effective as it reaches more ganglia. The aim of this study was to compare the(More)
BACKGROUND & AIMS Capsule endoscopy (CE) is used most frequently to identify causes of obscure gastrointestinal bleeding (OGIB). Identifying factors associated with the detection of lesions by CE could improve resource utilization and thereby improve patient selection for CE examination. We sought to identify clinical factors associated with positive(More)
BACKGROUND Low-volume bowel preparations are ideal to ensure patient compliance, thus enabling high-quality examinations to be achieved. OBJECTIVES To examine the bowel-cleansing efficacy and patient tolerability of split-dose 2 L PEG3350 + electrolytes (PEG3350e) with 15 mg bisacodyl versus split-dose 4 L PEG3350e. DESIGN Single-blinded,(More)
Deletion of 11q23 is a common genetic aberration in nasopharyngeal carcinoma (NPC). Multiple candidate tumor suppressor genes (TSG) were mapped to this region but few of them were investigated in NPC. TSLC1 (tumor suppressor in lung cancer) is recently reported to be a putative TSG on 11q23. This gene was found to be inactivated by promoter hypermethylation(More)
AIM To evaluate the yield of brushing biliary strictures and the factors associated with a positive result in biliary strictures. METHODS Data on all consecutive patients (01/02-10/05) who were identified to have a biliary stricture and who underwent biliary brush cytology were collected. The yield of positive biliary brush cytology was evaluated and(More)
AIM To identify patient risk factors associated with incomplete small bowel capsule endoscopy (CE) studies. METHODS Data from all CE procedures performed at St. Paul's Hospital in Vancouver, British Columbia, Canada, between December 2001 and June 2008 were collected and analyzed on a retrospective basis. Data collection for complete and incomplete CE(More)
BACKGROUND Fluoroscopy during ERCP has a linear relationship with radiation, carrying risk of exposure. OBJECTIVE To determine patient, physician, and procedural factors affecting fluoroscopy duration. DESIGN Prospective analysis of ERCPs with evaluation of patient, physician, and procedural variables. SETTING Two tertiary-care hospitals. PATIENTS(More)
