The preparation for video capsule endoscopy (VCE) of the bowel suggested by manufacturers of capsule endoscopy systems consists only of a clear liquid diet and an 8-hour fast. While there is evidence for a benefit from bowel preparation for VCE, so far there is no domestic consensus on the preparation regimen in Korea. Therefore, we performed this study to recommend guidelines for bowel prepara...

During video capsule endoscopy (VCE), several factors, such as air bubbles, food material in the small bowel, and delayed gastric and small bowel transit time, influence diagnostic yield, small bowel visualization quality, and cecal completion rate. Therefore, bowel preparation before VCE is as essential as bowel preparation before colonoscopy. To date, there have been many comparative studies,...

Phytocannabinoids that do not produce psychotropic effects are considered of special interest as novel therapeutic agents in CNS diseases. A cannabigerol quinone, the compound VCE-003, has been shown to alleviate symptoms in a viral model of multiple sclerosis (MS). Hence, we studied T cells and macrophages as targets for VCE-003 and its efficacy in an autoimmune model of MS. Proliferation, cel...

BACKGROUND Chronic abdominal pain (CAP) is a common indication for gastroenterology referrals. More insidious causes of CAP isolated to the small bowel, such as malignancies and Crohn's disease, are rising in incidence and causing more gastroenterologists to evaluate their patients with video capsule endoscopy (VCE). However, the role of VCE in patients with CAP is still unclear. AIMS We asse...

The diagnosis and management of obscure gastrointestinal bleeding (OGIB) have changed dramatically since the introduction of video capsule endoscopy (VCE) followed by deep enteroscopy and other imaging technologies in the last decade. Significant advances have been made, yet there remains room for improvement in our diagnostic yield and treatment capabilities for recurrent OGIB. In this review,...

This paper proposes variance component estimation (VCE) for empirical quality evaluation in computer vision. An outline is given for the scope of VCE in the context of quality evaluation. The principle of VCE is explained and the approach is applied to results of low level feature extraction. Ground truth is only partly needed for estimating the precision, accuracy and bias of extracted points ...

BACKGROUND AND STUDY AIM Small-bowel tumors account for 1% - 3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tum...

VCE is an ethylene, vinyl acetate, vinyl alcohol elastomer used to bind high volumes of microparticles. Surveillance data for this material is both scarce and scattered, complicating the assessment of any aging trends in systems. In addition, most of the initial surveillance efforts focused on mechanical properties such as hardness and tensile strength, and chemical information is therefore lac...

Video capsule endoscopy (VCE) is a useful diagnostic tool in patients with unknown blood loss, particularly when there is a high suspicion of small bowel disease, but because of its use of radio frequency, it is relatively contraindicated in patients with a cardiac device. We report the case of a patient with an implantable cardiac defibrillator (ICD) who underwent VCE because of anaemia and pr...

Video capsule endoscopy (VCE) is an ingestible video camera that transmits high-quality images of the small intestinal mucosa. This makes the small intestine more readily accessible to physicians investigating the presence of small bowel disorders, such as Crohn's disease (CD). Although VCE is frequently performed in Korea, there are no evidence-based guidelines on the appropriate use of VCE in...
