BACKGROUND Barrett's esophagus, a condition of intestinal metaplasia of the esophagus, is associated with an increased risk of esophageal adenocarcinoma. We assessed whether endoscopic radiofrequency ablation could eradicate dysplastic Barrett's esophagus and decrease the rate of neoplastic progression. METHODS In a multicenter, sham-controlled trial, we(More)
The guidelines for the diagnosis, surveillance and therapy of Barrett’s esophagus were originally published by the American College of Gastroenterology in 1998 and updated in 2002. These and other guidelines undergo periodic review. Significant advances have occurred in the area of Barrett’s esophagus over the past four years leading to another revision of(More)
CONTEXT Severe gastroesophageal reflux disease (GERD) is a lifelong problem that can be complicated by peptic esophageal stricture and adenocarcinoma of the esophagus. OBJECTIVE To determine the long-term outcome of medical and surgical therapies for GERD. DESIGN AND SETTING Follow-up study conducted from October 1997 through October 1999 of a(More)
BACKGROUND & AIMS The exact incidence of adenocarcinoma in patients with Barrett's esophagus (BE) is not known and is reported to vary from 0.2%-2% per year. Published series of patients with BE have included relatively small numbers of patients with limited duration of follow-up. The goal of this study was to define the prevalence and incidence of(More)
BACKGROUND Chronic liver disease develops in more than half of patients with post-transfusion hepatitis C, but little is known about the natural history of community-acquired hepatitis C. METHODS In 1985 and 1986 we identified adults with acute non-A, non-B hepatitis in four counties in the United States and followed them prospectively. We used three(More)
BACKGROUND & AIMS Outcomes of colon surveillance after colorectal cancer screening with colonoscopy are uncertain. We conducted a prospective study to measure incidence of advanced neoplasia in patients within 5.5 years of screening colonoscopy. METHODS Three thousand one hundred twenty-one asymptomatic subjects, age 50 to 75 years, had screening(More)
BACKGROUND & AIMS The diagnosis and management of Barrett's esophagus (BE) are controversial. We conducted a critical review of the literature in BE to provide guidance on clinically relevant issues. METHODS A multidisciplinary group of 18 participants evaluated the strength and the grade of evidence for 42 statements pertaining to the diagnosis,(More)
BACKGROUND & AIMS The risks of dysplasia and esophageal adenocarcinoma (EAC) are not clear for patients with nondysplastic Barrett's esophagus (NDBE); the rate of progression has been overestimated in previous studies. We studied the incidences of dysplasia and EAC and investigated factors associated with progression of BE. METHODS The BE study is a(More)
An important determinant in interpreting the results of colorectal polyp chemoprevention trials is the rate of polyps missed during colonscopic examination. We prospectively examined 90 patients by tandem colonoscopy performed by two alternating examiners. In 69 (76.7%) patients, 221 neoplastic lesions were documented histologically. Of a total of 58(More)
