BACKGROUND:  In view of the increased risk of developing colorectal cancer (CRC) in individuals with affected first-degree relatives (FDRs), the German evidence-based S3 guideline recommends having the first screening colonoscopy early and then, following a normal examination, repeating it at least every 10 years. The aim of this analysis was to explore colonoscopy interval recommendations in clinical practice among individuals aged < 55 years with a familial risk of CRC. METHODS:  We analyzed data from the FRIDA...

BACKGROUND: A target goal for screening adenoma detection rate (S-ADR) of ≥ 25% has been set to define high-quality colonoscopy performance. However, there is no current accepted target goal for ADR in colorectal cancer (CRC) surveillance. This makes quality assessment challenging when physicians perform cancer surveillance colonoscopy but minimal screening procedures. METHODS: In this cohort study, consecutive colonoscopies performed at either Rush University Medical Center or Rush Oak Park Hospital by a gastroenterologist or colorectal surgeon in average risk screening population and CRC surveillance population were reviewed retrospectively from 2006 to 2012 and prospectively from 2013 to 2016...

INTRODUCTION: Transgender (trans) and gender-nonconforming adults have reported reduced access to health care because of discrimination and lack of knowledgeable care. This study aimed to contribute to the nascent cancer prevention literature among trans and gender-nonconforming individuals by ascertaining rates of breast, cervical, prostate, and colorectal cancer screening behaviors by gender identity. METHODS: Publicly available de-identified data from the 2014-2016 Behavioral Risk Factor Surveillance System surveys were utilized to evaluate rates of cancer screenings by gender identity, while controlling for healthcare access, sociodemographics, and survey year...

BACKGROUND: The association of proximal small and diminutive hyperplastic polyps (HPs) with synchronous neoplasia (AN) is not well defined. However, sessile serrated polyps, even when small, are known to portend synchronous neoplastic risk. Currently, when proximal small hyperplastic polyps are detected, the USMTF does not recommend a change in surveillance interval. We aimed to compare the rates of synchronous AN in a screening colonoscopy cohort of patients with small and then diminutive proximal HPs in comparison, first to a cohort absent any serrated or proximal hyperplastic polyps, and then in comparison with a cohort with small proximal sessile serrated polyps (SSPs)...

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...

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...

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...

BACKGROUND AND AIMS: Colorectal cancers (CRCs) diagnosed between 6 and 36 months after colonoscopy, termed postcolonoscopy CRCs (PCCRCs), arise primarily due to missed or inadequately treated neoplasms during colonoscopy. Quality indicators and technological advances have been introduced to colonoscopy practice that should have reduced the PCCRC rate over time. We assessed temporal trends in the population rate of PCCRC as a measure of changing colonoscopy quality. METHODS: We conducted a population-based retrospective cohort study of 50- to 74-year-old people without major risk factors for CRC who underwent complete colonoscopy in Ontario, Canada between 1996 and 2010...

Background/Aims: Because of the national screening program for colorectal carcinoma in The Netherlands, the number of colonoscopies has increased. In case of incomplete colonoscopy, computed tomography colonography (CTC) and double-balloon colonoscopy (DBc) are alternative options. This study evaluated cecal intubation rate and pathology detection rate in the previously unexplored part of the colon, complication rate of DBc, and CTC results after incomplete colonoscopy. Methods: Retrospective observational study in a tertiary referral hospital regarding DBc and CTC reports from cases with incomplete colonoscopy...

BACKGROUND AND AIM: Colonoscopic surveillance is recommended in patients with longstanding inflammatory bowel disease (IBD) as they are at increased risk of colorectal cancer (CRC). Non-invasive surveillance may improve compliance and access. Multi-target stool DNA (MT-sDNA) has been validated for screening of sporadic CRC but has not been assessed in IBD. Our aim was to assess the performance of a MT-sDNA test in a real-life surveillance setting of patients with longstanding IBD. MATERIAL AND METHODS: A total of 192 IBD patients enrolled from two prospective cohorts submitted an EDTA buffered stool sample and underwent chromo- or white light colonoscopy...

This report describes a case of rapidly growing colon cancer confirmed by computed tomographic colonography (CTC). A 75-year-old woman presented at our clinic with complaints of abdominal discomfort and melena. Colorectal examination was performed via CTC. The findings were normal. Sixteen months later, she was referred to our clinic again for positive findings on a faecal immunochemical screening test. A repeat CTC was performed, which revealed a 3 cm ulcerated tumour at the ascending colon. Colonoscopy with biopsy revealed tubular adenocarcinoma...

INTRODUCTION: Colorectal cancer screening programmes have been shown to reduce incidence and mortality. High-risk adenomas (HRA) are the most frequently diagnosed lesions in these programmes, and these patients are referred to a specialist. However, few studies have evaluated the adherence of HRA patients to the recommended endoscopic follow-up. OBJECTIVES: To analyse follow-up adherence and duration in patients diagnosed with HRA in a screening programme. METHODS: Retrospective cohort study of patients diagnosed with HRA within one of the participating hospitals of the colorectal cancer screening programme of Barcelona, during the first round of the programme (2010-2011)...

Neural lesions of the colon may be masses (schwannomas and neurofibromas) or, more frequently, small polyps including perineuromas, ganglioneuromas and granular cell tumors. Some neural lesions are associated with congenital syndromes (neurofibromatosis-1, multiple endocrine neoplasia-2B). Recently, a new entity has been described named mucosal Schwann cell hamartoma, consisting of an intramucosal neural proliferation; to date, less than forty cases have been reported. We report a further case in a patient from whom a polyp was extirpated during colonoscopy screening...

BACKGROUND & AIMS: Improved therapy has substantially increased survival of persons with cystic fibrosis (CF). But the risk of colorectal cancer (CRC) in adults with CF is 5-10 times greater compared to the general population, and 25-30 times greater in CF patients after an organ transplantation. To address this risk, the CF Foundation convened a multi-stakeholder task force to develop CRC screening recommendations. METHODS: The 18-member task force consisted of experts including pulmonologists, gastroenterologists, a social worker, nurse coordinator, surgeon, epidemiologist, statistician, CF adult, and a parent...

The objective of this meta-analysis is to evaluate the odds of colorectal adenoma (CRA) in colorectal cancer screening participants with different body mass index (BMI) levels, and examine if this association was different according to gender and ethnicity. The EMBASE and MEDLINE were searched to enroll high quality observational studies that examined the association between investigator-measured BMI and colonoscopy-diagnosed CRA. Data were independently extracted by two reviewers. A random-effects meta-analysis was conducted to estimate the summary odds ratio (SOR) for the association between BMI and CRA...

BACKGROUND: Flexible sigmoidoscopy and fecal immunochemical tests are established diagnostic tests for colorectal cancer (CRC) screening and less invasive, less expensive, and easier to conduct than colonoscopy. However, little is known about their joint diagnostic performance compared to colonoscopy. We aimed to assess the expected diagnostic performance of joint use of flexible sigmoidoscopy and fecal immunochemical test. METHODS: We assessed the overall and site-specific prevalences of colorectal neoplasms and the overall and site-specific sensitivity, specificity, area under the receiver operating characteristics curve of a quantitative fecal immunochemical test (FOB Gold) among 3,466 participants in screening colonoscopy in Germany...
