Development of a Colonoscopy Simulator for the Evaluation of Colonoscopy Devices
Colonoscopy is the current standard for colorectal cancer screening. This procedure requires improvement since it causes patient pain and can even result in injury. Novel colonoscopy devices have to be evaluated to gain information about their performance. At the preclinical stage of the device …

Polyp Detection in Colonoscopy Video
Colonoscopy is the only screening that can detect polyps in the colon that can mutate into colorectal cancer. The task of detecting polyps is a job done by the doctors themselves who perform the procedure. It often happens that polyps are not recognized for reasons such as fatigue of the doctor …

Colonoscopy cleanout education and outcome optimization
Colonoscopy is a frequently employed diagnostic tool used in the assessment of pediatric patients with known or suspected GI disease. Common indications for the procedure in pediatric patients include chronic diarrhea, hematochezia, or inflammatory bowel disease (IBD). In preparing a patient for …

In-Vivo Ct Dosimetry During Virtual Colonoscopy
<p>Virtual colonoscopy (VC) is a minimally invasive means for identifying colorectal polyps and colorectal lesions by insufflating a patient’s bowel, applying contrast agent via rectal catheter, and performing multi-detector computed tomography (MDCT) scans. The technique is recommended for colonic …

Evaluation of an Active Colonoscopy Training Model
… is to evaluate the effectiveness of an Active Colonoscopy Training Model (ACTM). To make learning and assessing the colonoscopy procedural skills easy and interactive, an active training model is being developed and evaluated. To measure the applied forces load cells are used. The time to …

Real-time Quality Feedback System for Screening Colonoscopy
Colonoscopy is the gold standard method for the diagnosis of colorectal cancer and the identification of precancerous polyps. Unfortunately, there is not yet a metric (formally recommended by consensus guidelines) for the quantification of colonoscopy quality. Though, there are established quality …

Bowel preparation for colonoscopy: is diet restriction necessary?
… Bowel preparation is essential for quality colonoscopy. Although most bowel preparation regimens recommend dietary restriction for 24 to 48 hours before the procedure, the evidence for this is poor. Objectives: To establish whether dietary restriction during bowel preparation improves the …

Feature Extraction and Feasibility Study on CT Image Guided Colonoscopy
… colonography(CTC), also called virtual colonoscopy, uses CT scanning and computer post-processing to create two dimensional images and three dimensional virtual views inside of the colon. Computer-aided polyp detection(CAPD) automatically detects colonic polyps and presents them to the …

Determining Best Practice for Colonoscopy Preparation for Persons with Constipation
… colorectal cancer is by early detection through colonoscopy starting at age 50 or, age 40 if there is a strong family history. To cleanse the bowel for this procedure, patients drink a preparation (prep) fluid that induces bowel evacuation. If the preparation is poor, polyps, abnormal tissue, or …

Ultrahigh-Resolution Endoscopic Optical Coherence Tomography for In Vivo Mouse Colonoscopy
In vivo monitoring of mouse models of colon cancer promises to reduce the cost of research by improving sacrifice timing and allowing serial studies that observe the progression of disease and drug efficacy in a relatively small set of animals. Optical coherence tomography (OCT) is an optical …

The Effects of Walking before Colonoscopy on Colon Cleansing and Discomfort
… to investigate the effects of walking before colonoscopy on colon cleansing and discomfort. A total of 133 patients who scheduled for colonoscopy to be performed at Ajou university hospital in Suwon, South Korea were randomly allocated to an experimental group (n=65) and a control group …

Development of an Endoscope Propulsion System to Aid in the Colonoscopy Procedure
… Propulsion System, or EPS, will assist in the colonoscopy procedure. This device will enable a lesser skilled physician to effectively perform the colonoscopy, thus increasing the procedure's availability. In addition to requiring less skill, the assistive nature of the EPS will also decrease …

Total colonoscopy versus double-contrast barium enema for the detection of intraluminal lesions.
… enema (DCBE) is slowly being superseded by total colonoscopy (TC), as the latter is alleged to have better sensitivity and specificity to detect colorectal pathology. Research has also revealed that DCBE tends to have a higher degree of misdiagnoses when compared to TC. Therefore, physicians are …

The yield of colonoscopy in patients attending a tertiary hospital in Cape Town, South Africa
Background: Colonoscopy is widely used for diagnosis, therapeutic intervention of conditions of the lower gastrointestinal tract and colorectal cancer screening. Given its widespread use and complications, colonoscopy should be performed for appropriate indications. The aim of this study was to …

Cancer free survival in mutation positive HNPCC individuals with colorectal adenomatous polyps identified on surveillance colonoscopy
The prevalence of colorectal cancer (CRC) places it in the top five cancers worldwide and is the second most common cause of cancer related death. Developed populations have a 5-6% lifetime risk of CRC(l). The South African Cancer Registry (last updated 2004) shows a 1/98 and 1/150 life time risk …

The Detection and Characterization of Severe Features in Colonoscopy Videos Using Combined Segmentation and Classification Models
… requires regular monitoring procedures, such as colonoscopy. Assessing disease severity through endoscopy is critical to determining therapeutic responses in IBD, but its use in clinical practice is limited by the requirement for experienced human reviewers. In recent development, artificial …

The Safety and Efficacy of Oral Low-Volume Sodium Phosphate Bowel Preparation for Colonoscopy in Dogs
… received each of 6 bowel preparations prior to colonoscopy performed one time per week. An observer blinded to the bowel preparation assigned a score of 1-4 (1 clean colon and ≥3 unacceptable preparation) to each of 5 regions of the colon. Mean total colon cleansing score (TCS), defined as the …

Improving Health Literacy of Colonoscopy Patients Through Reinforced Teaching of Bowel Preparation Using Pre-Procedure Phone Calls
… <p>Medicare/MediCal patients undergoing colonoscopy procedures at East Bay Endoscopy Center (EBEC), were found to have inadequate cleansing of the bowel due to poor compliance and adherence to prep instructions. Poor health literacy affects the vulnerable population seen in …
