BACKGROUND/AIMS We evaluated whether colonic transit time (CTT) can predict the degree of bowel preparation in patients with chronic constipation undergoing scheduled colonoscopy in order to assist in the development of better bowel preparation strategies for these patients. METHODS We analyzed the records of 160 patients with chronic constipation from March 2007 to November 2012. We enrolled...

BACKGROUND Bowel preparation is inadequate in a large proportion of colonoscopies, leading to multiple clinical and economic harms. While most patients receive some form of education before colonoscopy, there is no consensus on the best approach. AIMS This systematic review aimed to evaluate the efficacy of patient education interventions to improve bowel preparation. METHODS We searched th...

PURPOSE To assess whether bowel preparation prior to kidney-ureter-bladder (KUB) radiography and intravenous urography (IVU) are of value in improving visualization of the urinary system. MATERIALS AND METHODS A total of 186 patients participated in this study. Thirty-nine patients with chronic constipation based on Rome III criteria and 147 patients with normal bowel habits were included. Al...

Polyethylene glycol (PEG) electrolyte solution can induce potentially fatal complications when used as a lavage in preoperative bowel preparation. A 60-year-old man with carcinoma of the esophagogastric junction had a Mallory-Weiss tear after bowel preparation with PEG. He was successfully resuscitated, first with balanced salt solution then by transfusion. The literature on the subject is revi...

Bowel preparation is important when visualizing the whole colonic mucosa and greatly influences the rate of adenoma detection, which is considered to be a standard indicator of successful colonoscopy. 1 The target level of adequate preparation (so that repeat colonoscopy is not required within ≤1 year) is 85% as recommended by the American Society for Gastrointestinal Endoscopy (ASGE)/the Ameri...

BACKGROUND Standard-volume polyethylene glycol (PEG) gut lavage solutions are safe and effective, but they require the consumption of large volumes of fluid. A new lower-volume solution of PEG plus ascorbic acid has been used recently as a preparation for colonoscopy. AIM A meta-analysis was performed to compare the performance of low-volume PEG plus ascorbic acid with standard-volume PEG as ...

BACKGROUND The value of the preparation of the colon prior colorectal surgery remains debatable. Since installed as traditional the use of this routine, few studies have been conducted to support the safety of surgeries done without mechanical bowel preparation. AIM To determine if there is a correlation between postoperative complications and no use of mechanical bowel preparation in operate...

Background and study aim  Few scales assessing bowel preparation quality have been validated, and direct between-scale comparisons remain scarce. The aim of the study was to compare inter- and intra-rater reliability, predictive abilities for clinical outcomes, and ease of use for each scale. Methods  Colonoscopy video recordings highlighting five colonic segments after washing were viewed in...

This is one of a series of documents discussing the use of GI endoscopy in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy prepared this document that updates a previously issued consensus statement and a technology status evaluation report on this topic. In preparing this guideline, a search of the medical literature was pe...
