BACKGROUND & AIMS Adenocarcinoma of the esophagus and esophagogastric junction (EGJ) is increasing, the earliest lesion being specialized intestinal metaplasia (SIM). This study determined the prevalence and demographic features of patients with SIM, dysplasia, and cancer in the esophagus and EGJ. METHODS Two antegrade biopsy specimens were taken distal(More)
BACKGROUND Some patients with a phenotypic appearance of eosinophilic oesophagitis (EoE) respond histologically to PPI, and are described as having PPI-responsive oesophageal eosinophilia (PPI-REE). It is unclear if PPI-REE is a GERD-related phenomenon, a subtype of EoE, or a completely unique entity. AIM To compare demographic, clinical and histological(More)
OBJECTIVES Patients with clinical symptoms of esophageal dysfunction and dense eosinophilic infiltration of the esophageal mucosa are suspected to have eosinophilic esophagitis (EoE). Topical steroids are often used as first-line therapy for EoE, although some patients respond clinically to proton pump inhibitors (PPIs). The purpose of this study was to(More)
BACKGROUND Baclofen, a GABA(B) agonist, has been shown to reduce transient lower oesophageal sphincter relaxations (TLESRs), a major cause of gastro-oesophageal reflux disease (GERD). AIM To examine the effect and tolerability of baclofen in GERD patients over a 2-week period. METHODS Forty-three GERD patients with abnormal 24-h pH tests were(More)
BACKGROUND There is limited data examining the prevalence of inflammatory bowel disease (IBD) in a diverse North American population. METHODS Using International Classification of Diseases, Ninth Revision codes, patients with Crohn's disease (CD) and ulcerative colitis (UC) seen within the military health care system (Tricare) from October 1, 2008 to(More)
OBJECTIVES Upper gastrointestinal bleeding (UGIB) remains a commonly encountered medical emergency with significant morbidity and mortality. Most large studies detailing the specific incidence, demographic, and mortality data were performed more than a decade ago. This study analyzes 3,294 cases of UGIB from 139 military medical treatment facilities over a(More)
OBJECTIVE The purpose of this study is to evaluate the impact of extracolonic findings when screening is undertaken by CT colonography (CTC). MATERIALS AND METHODS We performed a retrospective cohort study of patients completing a screening CTC from August 2003 to June 2006 at Walter Reed Army Medical Center. Extracolonic findings were categorized using a(More)
OBJECTIVE While colonoscopy is currently the preferred test for colorectal cancer (CRC) screening, the invasive and time-consuming characteristics of the test are often cited as reasons for noncompliance with screening. CT colonography (CTC) is a less invasive screening method that is comparable to colonoscopy for the detection of advanced neoplasia. The(More)
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) is characterized by eosinophilic infiltration of the esophagus. The purpose of this prospective study was to determine the prevalence and clinical predictors of EoE in patients undergoing elective upper endoscopy. METHODS We enrolled 400 consecutive adults (median age, 50 years; range, 19-92 years) who(More)
We studied the effects of three smooth muscle relaxants on lower esophageal sphincter (LES) pressure and radionuclide esophageal emptying in 15 untreated patients with achalasia. LES pressures were determined before and after the administration of normal saline subcutaneously, terbutaline sulfate subcutaneously, nitroglycerin sublingually, and aminophylline(More)
