BACKGROUND & AIMS Endoscopist-directed propofol sedation (EDP) remains controversial. We sought to update the safety experience of EDP and estimate the cost of using anesthesia specialists for endoscopic sedation. METHODS We reviewed all published work using EDP. We contacted all endoscopists performing EDP for endoscopy that we were aware of to obtain(More)
BACKGROUND Lubiprostone, a selective activator of type 2 chloride channels, is approved for treatment of chronic idiopathic constipation and recently constipation-predominant irritable bowel syndrome. It has been suggested that lubiprostone has a prokinetic effect. OBJECTIVE This investigation was designed to evaluate lubiprostone as a preparation and(More)
OBJECTIVES We sought to evaluate a new, low-volume, oral sulfate solution as a bowel preparation for colonoscopy in adult patients. METHODS The investigations were designed as two multicenter, single-blind, randomized, non-inferiority studies to show that the sulfate regimen would effect cleansing that is acceptable and equivalent to polyethylene glycol(More)
BACKGROUND Low-volume bowel preparations for colonoscopy improve tolerability. OBJECTIVE We compared the efficacy, tolerability, and safety of a new low-volume sulfate solution with a standard 4-L polyethylene glycol electrolyte lavage solution as bowel preparation for colonoscopy. DESIGN Multicenter, single-blind, randomized, noninferiority study. (More)
The process of stool transfer from healthy donors to the sick, known as faecal microbiota transplantation (FMT), has an ancient history. However, only recently researchers started investigating its applications in an evidence-based manner. Current knowledge of the microbiome, the concept of dysbiosis and results of preliminary research suggest that there is(More)
OBJECTIVE Polyethylene glycol (PEG) 3350 (MiraLax) and tegaserod (Zelnorm), a serotonin subtype 4 receptor partial agonist, are currently approved for treatment of constipation. This study was designed to compare the efficacy of each product over a 4-wk treatment period. METHODS Study patients who met defined criteria for chronic constipation were(More)
Our purpose was to evaluate the durability of the diagnosis of irritable bowel syndrome (IBS) based on clinical criteria. The study population consisted of a cohort of previously published study patients evaluated for IBS between 1989 and 1992, who met the International Congress of Gastroenterology criteria for IBS. Patients were reinterviewed for cardinal(More)
Colonoscopy requires adequate bowel cleansing to be safe and effective. Current options for preparation include dietary restrictions plus cathartics and purgatives, large-volume gut lavage solutions, and sodium phosphate preparations. Gut lavage with or without a stimulant laxative is safe and effective, and traditionally is taken the evening before the(More)
The success and accuracy of colonoscopy is largely dependent on appropriate cleansing of the colon. The ideal bowel preparation should be safe, well-tolerated and effective. Although colonoscopy preparations are vastly better than the earliest barium enemas used in X-ray regimens, none of the currently available formulations sufficiently fulfills the above(More)
OBJECTIVES Clinical studies in constipated adult patients have shown that a 17- or 34-g daily dose of polyethylene glycol (PEG) 3350 (MiraLax) is safe and effective for the treatment of constipation, with the best efficacy seen in wk 2 of treatment. The purpose of this study was to determine an optimal dose of PEG to provide satisfactory relief of(More)
