bowel preparation colonoscopy

Michael R Kolber, Shelley Ross
BACKGROUND AND OBJECTIVES: In Canada, few family physicians (FPs) perform endoscopy. Conflicting evidence exists on the quality of endoscopy performed by Canadian FPs, which may be explained by differing skillsets of these endoscopists. The objective of this study was to perform the first exploration of the practice, skills, and knowledge of Canadian FP endoscopists. METHODS: A cross-sectional survey, including direct knowledge test, was used. RESULTS: Twenty Canadian FP endoscopists completed the survey...

OBJECTIVES: Split dose of 4 l polyethylene glycol (PEG) is currently the standard regimen for bowel preparation (BP). However, it may be unnecessary for patients without high risks (e.g., old age, constipation, and diabetes, and so on) for inadequate BP. The study aimed to compare the efficacy of bowel cleansing between low-risk patients receiving same-day, single dose of low-volume (SSL) PEG vs. standard regimen. METHODS: This prospective, randomized, observer-blinded, non-inferiority study enrolled low-risk patients in three centers...

PURPOSE: Cecal intubation time (CIT) is an indicator for difficult colonoscopy which is associated with patients' unpleasant experience as well as increased risk of complications. Several studies have attempted to identify predictors for prolonged CIT but those studies tended to be small which gave rise to inconsistent and underpowered results. This systematic review and meta-analysis was conducted to summarize all available data. METHODS: MEDLINE and EMBASE databases were searched through November 2017 for studies that investigated the factors for prolonged CIT...

Background: A split-dose (SD) regimen is crucial for colonoscopy quality. Compliance with SD for early morning colonoscopy is generally poor. The present study evaluated whether pre-colonoscopy counselling, in addition to a dedicated leaflet, might increase SD uptake. Methods: Consecutive 50-69-year-old patients undergoing screening colonoscopy before 10 a.m. were randomized to either receive written information only on bowel preparation (Written Group, WG) or written and oral instructions (Written and Oral Group, WaOG)...

Background: Colonoscopy procedures are commonly performed and have high success rates. However, poor or inadequate bowel preparation is one of the most common reasons for a repeated or failed colonoscopy. We therefore performed an observational study followed by propensity score modeling to evaluate and compare the quality of bowel preparation with the use of Aquanet bowel cleansing devices (BCDs) versus the use of oral sodium picosulfate solution. Methods: We performed a prospective cross-sectional study to compare the quality of pre-endoscopic bowel preparation using a BCD with oral solution...

CT colonography (CTC) has demonstrated equivalent accuracy to optical colonoscopy in the detection of clinically relevant polyps and tumors but this is only possible when technique is optimized. The two most important features of a high-quality CTC are a well-prepared colon and a distended colon. This article will discuss the dietary, bowel preparation, and fecal/fluid tagging options to best prepare the colon. Strategies to optimally distend the colon will also be discussed. CT scan techniques including patient positioning and radiation dose optimization will be reviewed...

A theory-driven tailored intervention developed in partnership with the community used evidence-based practices to (a) increase knowledge about colon cancer and screening and (b) assist patients in completing screenings. During the 16 months of delivery screening, patient navigators integrated into gastroenterology clinics met all goals, which included (a) enrolling an ethnically diverse group of participants ( N = 415) through inreach (clinic-referred patients who did not schedule appointments) and community outreach, (b) facilitating screening completions for 217 of the 358 (61%) patients identified as needing screening, and (c) obtaining satisfaction ratings from 89% of participants...

BACKGROUND: Cancer screening rates are lowest in those without insurance or a regular provider. Since 2008, the Colorectal Cancer Prevention Network (CCPN) has provided open access colonoscopy to uninsured residents of South Carolina through established, statewide partnerships and patient navigation. Herein, we describe the structure, implementation, and clinical outcomes of this program. METHODS: The CCPN provides access to colonoscopy screening at no cost to uninsured, asymptomatic patients aged 50-64 years (African Americans age 45-64 years are eligible) who live at or below 150% of the poverty line and seek medical care in free medical clinics, federally qualified health centers, or hospital-based indigent practices in South Carolina...

PURPOSE OF REVIEW: Colonoscopy is the gold standard for visualization and diagnosis of conditions involving the colon and terminal ileum. It also facilitates screening and prevention of colorectal cancer, which is the second leading cause of cancer death in the USA. Adequate cleansing is essential for thorough visualization of the colon with successful detection of colon polyps. RECENT FINDINGS: While the original large-volume polyethylene glycol preparations are still commonly used, several lower volume regimens are widely available and selected based on provider and patient preferences...

BACKGROUND/AIMS: Adequate bowel preparation is essential for an effective and safe colonoscopy. This study aimed to evaluate the quality of bowel preparation according to waiting times from education to colonoscopy. MATERIALS AND METHODS: A prospective, investigator-blinded, randomized study was performed from December 2016 to March 2017. Patients were divided into two groups: within 2 weeks (group A, n=64) or more than 2 weeks (group B, n=66) from education about bowel preparation to colonoscopy...

BACKGROUND/AIMS: Polyethylene glycol (PEG)-3350, approved by Food and Drug Administration (FDA) only for constipation, combined with 1.9 L of sports drink (SD) (GatoradeR) and bisacodyl (B) is commonly used in outpatient practice for bowel preparation due to cited patient satisfaction and tolerability of this specific regimen. We aim to compare PEG-3350 (MiralaxR) with PEG-AA-based (MoviPrepR) in terms of efficacy, patient satisfaction, and the effects of these two regimen on serum electrolytes...

The safety of bowel-cleansing agents is an important issue in clinical practice, especially in patients with chronic diseases. Although the safety and efficacy of polyethylene glycol (PEG) has been investigated in many studies, few studies on PEG plus ascorbic acid exist. In this study, we compared the safety of 2 bowel-cleansing agents for patients with liver cirrhosis: 2-liter PEG (2 L PEG) plus ascorbic acid versus 4-liter PEG (4 L PEG). We performed a retrospective study on colonoscopy in patients with liver cirrhosis...

BACKGROUND [color=black]Bowel preparation is an important factor for an optimal outcome of colonoscopy. Recently, polyethylene glycol (PEG) solution has been in common use for bowel cleansing for colonoscopy, but some patients are intolerant of PEG because of taste or volume. A low-volume PEG administered with ascorbic acid solution (PEG-Asc) was designed to improve tolerability, but the administration of this method is more complex than that with PEG alone. This study aimed to compare bowel cleansing efficacy, safety, and tolerability of 1 L PEG-Asc with a 2 L PEG preparation with use of sennosides and mosapride...

BACKGROUND: Because of its volume, adequate bowel preparation remains problematic in physically unfit patients. OBJECTIVE: This study aimed to compare a small-volume sodium picosulfate/magnesium citrate preparation with a 2-L ascorbic acid-enriched polyethylene glycol solution plus bisacodyl. DESIGN: This study has a noninferiority design, assuming that ascorbic acid-enriched polyethylene glycol solution plus bisacodyl is 70% efficacious in achieving an Ottawa score ≤7 and accepting a difference in success rate of <15% with a target enrollment of 146 patients per group...

BACKGROUND AND AIMS: Bowel preparation for colonoscopy induces a semi-fasting state, with a potential negative impact on fragile patients. The present study aims to quantify nutritional deficiency during colonoscopy preparation. METHODS: This was an observational and cross-sectional study. A convenience sample was obtained that included adults that underwent colonoscopy after bowel preparation with Klean-Prep® according to the center protocol. Anthropometric evaluation was performed and nutritional deficiency was calculated via the quantification of energy and protein intake during the 48 hours prior to the examination which was compared with the individuals' needs...
