Background and study aims For bowel preparation, using a reduced volume of polyethylene glycol (PEG) solution without influencing its effectiveness would be preferable. While simethicone shows great potential as an adjunctive agent, data on its use are limited. We aimed to clarify whether simethicone added to low-volume PEG solution improved bowel cleansing. Patients and methods Consecutive adult patients registered for colonoscopy were recruited from seven medical centers in South China between 15 April and 15 July 2015 and prospectively randomized into two groups: 2 L PEG (conventional group) and 2 L PEG plus simethicone (simethicone group)...

BACKGROUND: Current bowel preparations for colonoscopy include a clear liquid diet (CLD) along with consumption of a laxative. This dietary restriction along with large volume bowel preparations are barriers to compliance and willingness among patients in scheduling screening examinations. The aim of our study was to compare the efficacy and tolerability of a low-volume split dose magnesium citrate bowel preparation in patients on a low-residue diet (LRD) with those on a CLD. METHODS: In this single center, single blinded, randomized controlled trial, patients scheduled for outpatient colonoscopies were assigned to either a CLD or a LRD 1 day before the examination...

BACKGROUND AND AIMS: Adequate bowel preparation is essential for a quality colonoscopy. Poor bowel preparation can result in longer procedural times, missed adenomas, earlier repeat procedures, increase costs, and decreased patient satisfaction [1-5]. Pure-Vu (MOTUS GI, Tirat Carmel, Israel) is a system that facilitates intra-procedural cleaning of a poorly prepared colon during a colonoscopy by irrigating the colon and evacuating the fluid and feces. The study aims were to evaluate Pure-Vu's cleansing capabilities and its usability and safety, in a live animal colon METHODS: The Pure-Vu system was used by four experienced gastroenterologists in 35 Yorkshire cross swine (66% female) that received a reduced bowel preparation to ensure an inadequate bowel preparation at baseline...

INTRODUCTION: Colonoscopy has been regarded as a standard method of detecting and removing gastrointestinal lesions early, while adequate bowel preparation is the prerequisite of determining the diagnostic accuracy and treatment safety of this process. Polyethylene glycol (PEG) based bowel preparation regimens remain the first recommendation, but the optimal option is still uncertain. The aim of this systematic review and network meta-analysis of randomised controlled trials (RCTs) is to determine the optimal PEG based bowel preparation regimen before colonoscopy...

Introduction Colonoscopy trainers have gained recognition for improving endoscopy skills and preparing for real procedures on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for small medical centers. However, a solution might be to construct a device for themselves. Aim Our goal was to build a relatively cheap and easy-to-construct simulator for residents who want to start learning colonoscopy. Materials and methods The box model colonoscopy trainer was designed and constructed...

Endoscopy has a key role in the management of inflammatory bowel disease (IBD). It is helpful in the diagnosis, in case of relapse, refractoriness, before therapeutic changes, after surgery as well as in the assessment of mucosal healing and in the surveillance of colo-rectal cancer. IBD patients are intended to undergo several times the examination during their lifespan. Bowel preparation and sedation highly contribute to high-quality colonoscopy. Areas covered: Few studies addressed preparation and sedation in the field of IBD...

Background and study aims Ideal bowel preparation for colonoscopy requires complete removal of fluid and foam from the colon. Polyethylene glycol (PEG) is widely used for bowel preparation, with antifoaming agents such as simethicone commonly used in combination with PEG. Data on the effect of simethicone on the adenoma detection rate (ADR) were limited. This study therefore aimed to investigate whether preprocedure simethicone could increase the ADR. Patients and methods This was a prospective, multicenter, endoscopist-blinded randomized controlled trial involving consecutive patients who underwent colonoscopy in six centers in China...

OBJECTIVE: Pain associated with colonoscopy is a major burden for patients. We investigated modifiable factors associated with patient-reported pain during and after colonoscopy. DESIGN: This cross-sectional analysis included database records from 23 centres participating in a population-based colonoscopy screening programme in Poland. Colonoscopies were performed under three sedation modalities: none, benzodiazepine-opioid sedation or propofol sedation. We used Gastronet (a validated tool) to assess patients' pain during and after colonoscopy; pain was scored on a four-point scale (no, little, moderate or severe pain), with moderate to severe defined as painful...

Clinical practice shows that patients with constipation are more likely to have a poor bowel preparation for colonoscopy. Consequences of poor bowel preparation include missed lesions, increased complication rates, and higher costs. Research on preparing constipated patients for colonoscopy with Food and Drug Administration-approved medications is scarce. This study included 372 patients and compared the effectiveness of high-volume (4 L) polyethylene glycol solution (GoLYTELY) with low-volume (2 L) polyethylene glycol solution with ascorbate (MoviPrep) in constipated and nonconstipated adults...
