AIM To compare the bowel cleansing efficacy of same day ingestion of 4-L sulfa-free polyethylene glycol (4-L SF-PEG) vs 2-L polyethylene glycol solution with ascorbic acid (2-L PEG + Asc) in patients undergoing afternoon colonoscopy. METHODS 206 patients (mean age 56.7 years, 61% male) undergoing outpatient screening or surveillance colonoscopies were(More)
OBJECTIVES Inadequate bowel preparation is a known factor associated with increased failure rates of afternoon colonoscopy and lower adenoma detection rates. The aim of our study was to compare the efficacy of bowel cleansing achieved by administering 1-gallon (4 l) polyethylene glycol (PEG) preparation to patients in the morning of an afternoon colonoscopy(More)
BACKGROUND Current guidelines recommend screening colonoscopy beginning at age 50 in the average-risk population. Race has been shown to influence the risk of colorectal cancer, thus leading to the recommendation of initiating screening in blacks at the age of 45. Few data exist on the prevalence of colon polyps among U.S. Hispanics. OBJECTIVES To compare(More)
BACKGROUND Recent studies have shown the adenoma detection rate (ADR) to decrease from endoscopist fatigue. OBJECTIVE Our primary objective was to evaluate the afternoon ADR in half-day versus full-day blocks. Secondary objectives were to determine whether time or complexity of prior procedures (modified queue position) influence ADR. DESIGN(More)
AIM To investigate the rates of polyp detection in a mixed risk population using standard definition (SDC) vs high definition colonoscopes (HDC). METHODS This was a retrospective cohort comparative study of 3 colonoscopists who each consecutively performed 150 SDC (307, 200 pixel) and 150 HDC (792, 576 pixels) in a community teaching hospital. RESULTS A(More)
BACKGROUND The USPSTF recommends beginning colorectal cancer screening at age 50. A recent study showed prevalence of colorectal adenomas among individuals aged 40-49 was similar to that among those aged 50-59. AIM To assess the prevalence of colorectal neoplasia, detected during colonoscopy, by age among average-risk patients. METHODS Nine-hundred and(More)
Screening for colorectal cancer (CRC) has been associated with a decreased incidence and mortality from CRC. However, patient adherence to screening is less than desirable and resources are limited even in developed countries. Better identification of individuals at a higher risk could result in improved screening efforts. Over the past few years, formulas(More)
Severe gastrointestinal (GI) hemorrhage is a rare complication of Crohn's disease (CD). Although several surgical and non-surgical approaches have been described over the last 2 decades this complication still poses significant diagnostic and therapeutic challenges. Given the relative infrequency of severe bleeding in CD, available medical literature on(More)
Two hundred and forty-one patients with at least one ulcer at stage A1 or A2, measuring at least 5 mm in its larger diameter, were included in this Brazilian double-blind randomized study. Patients received omeprazole 20 mg in the morning (n = 120) or ranitidine 300 mg at night (n = 121) for 2 wk; unhealed ulcers were treated for an additional 2 wk. At the(More)
