BACKGROUND: Colonoscopy screening and surveillance programs depend on patient's tolerable experience, which is associated with competence of the endoscopist. The Colonoscopy Progression Score (CoPS) is an automated tool based on recording of the Magnetic Scope Imager (MEI) picture in order to track progression. CoPS deliver a numeric score and a graphic map. A high score expresses a rapid and smooth progression. Aims of study were to explore the correlation between CoPS and patient experienced pain and to identity locations associated with pain...

Colonic diverticular bleeding is the most common cause of lower gastrointestinal bleeding1,2 . Appendiceal diverticulosis is an uncommon clinical entity, with an incidence of 0.004%-2% in surgical pathologic specimens3,4 . Appendiceal diverticulitis in symptomatic patients should be treated with early resection, because of the risk of perforation and peritonitis; the rate of perforation is higher in appendicitis (27%) with diverticulosis than in appendicitis alone (6.6%)5 . Untreated appendiceal diverticulitis can also lead to massive gastrointestinal hemorrhage and abscess formation, and has a potential role in the development of pseudomyxoma peritonei...

BACKGROUND: Colonoscopy is one of the excellent tools for screening colorectal cancer. There were four colonoscopy techniques containing air insufflation, CO2 insufflation, water exchange, and water immersion. Some studies reported that these methods are better than the criterion standard (air insufflation), while some studies showed not. In order to evaluate the efficacy of four colonoscopy techniques, a network meta-analysis was performed in present study. METHODS: We searched randomized controlled trials (RCTs) published up to September 2017 from PubMed, Embase, Cochrane library, and Web of Science...

Purpose: Because data as a basis for the determination of proper age and modality for screening of colorectal neoplasms is lacking, we evaluated detection rates and anatomical distribution of colorectal neoplasms according to age in healthy individuals who underwent total colonoscopy for health checkup. Methods: A total of 16,100 cases that had received the colonoscopic examination from January to December in 2014 were analyzed. The total number of individuals who received total colonoscopy were divided by the number of individuals harboring colorectal adenoma to calculate the detection rate of colorectal adenoma...

Background: Nearly 40% of colorectal cancer (CRC) recurs within 2 years after resection of primary tumor. Imaging with fluorine-18-fluorodeoxyglucose (l8F-FDG) positron emission tomography/computed tomography (PET/CT) is the most recent modality and often applied for the evaluation of metastatic spread during the follow-up period. Our goal was to study the diagnostic importance of 18F-FDG-PET/CT data of maximum standardized uptake value (SUVmax), total lesion glycolysis (TLG) and the difference of SUVmax on dual-time imaging in CRC...

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...

Colonoscopy is the gold standard for the study of colorectal pathology. Splenic injury is a rare but potentially fatal complication to consider. Therefore, we present two cases whose management was different and we show their clinical presentation, their diagnosis and their treatment in order to recognize this complication early to establish early treatment.

Inflammatory bowel diseases (IBD) in humans are characterized in part by aberrant CD4+ T cell responses. Currently, identification of foci of inflammation within the gut requires invasive procedures such as colonoscopy and biopsy. Molecular imaging with antibody fragment probes could be used to noninvasively monitor cell subsets causing intestinal inflammation. Here, GK1.5 cys-diabody (cDb), an anti-mouse CD4 antibody fragment derived from the GK1.5 hybridoma, was used as a positron emission tomography (PET) probe for CD4+ T cells in the dextran sulfate sodium (DSS) mouse model of IBD...

OBJECTIVES: The fecal immunochemical test (FIT) has low sensitivity for detecting advanced colorectal neoplasia (ACRN); thus, a considerable portion of FIT-negative persons may have ACRN. We aimed to develop a risk-scoring model for predicting ACRN in FIT-negative persons. MATERIALS AND METHODS: We reviewed the records of participants aged ≥40 years who underwent a colonoscopy and FIT during a health check-up. We developed a risk-scoring model for predicting ACRN in FIT-negative persons...

Somatic mutations in mitochondrial DNA have been reported in colorectal adenomatous polyps (adenomas), the precursors to most colorectal cancers. However, there are no reports of associations of germline variation in mitochondrial DNA with adenoma risk. We investigated associations of germline polymorphisms in the displacement loop (D-loop) and non-D-loop region of the mitochondrial genome with incident, sporadic colorectal adenoma in three pooled colonoscopy-based case-control studies (n = 327 adenoma cases, 420 controls) that used identical methods for case and risk factor ascertainment...

A single layer of epithelial cells separates luminal antigens from the host immune system throughout the gastrointestinal tract. A breakdown in the integrity of the epithelial barrier can lead to chronic inflammation, which is associated with numerous complications including cancer. Here we describe three experimental protocols to chemically induce acute and chronic inflammatory bowel disease (IBD) symptoms and colitis-associated colorectal cancer (CRC) progression. These in vivo mouse models are based on the induction of damage to the colonic epithelium, resulting in an inflammatory and wound healing response...
