Screening colonoscopy interval

BACKGROUND AND AIM: This study systematically reviewed and meta-analyzed the performance of the Asia-Pacific Colorectal Screening (APCS) score and its incorporation with the fecal immunochemical test (FIT) in stratifying the risk of advanced colorectal neoplasia (ACN). METHODS: We systematically searched for relevant articles in 12 electronic databases and registers on October 20, 2021, and updated the search to September 1, 2023. Random-effect models were used to obtain the pooled performance statistics of the APCS score for ACN risk...

AIM: Primary sclerosing cholangitis (PSC) increases the risk of colorectal cancer (CRC) in inflammatory bowel disease (IBD) patients; however, there is a paucity of literature to suggest PSC alone as an independent risk factor for CRC. We aimed to determine if PSC is an independent risk factor for CRC in a large tertiary care medical center. Optimizing screening intervals is of great importance, given the burden and risks associated with a lifetime of colonoscopy screening. METHODS: This retrospective cohort study consists of patients diagnosed with PSC preceding IBD (PSC-IBD) and PSC-only before January 6, 2023 from a large, tertiary, academic medical center...

BACKGROUND AND STUDY AIMS: Colorectal cancer (CRC) is one of the most common cancers worldwide, and most CRCs develop from polyps with malignant potential. We aimed to study the difference in polyp detection rate between EndoCuff-assisted colonoscopies (EAC) and standard colonoscopy (SC). PATIENTS AND METHODS: This study was conducted at Cairo University Hospitals on patients referred for screening or diagnostic colonoscopy from July 2018 to August 2020. All included patients underwent back-to-back standard colonoscopy (SC) and ENDOCUFF VISION-assisted colonoscopies (EAC)...

PURPOSE: To assess the comparative effectiveness of a tailored, interactive digital video disc (DVD) intervention versus DVD plus patient navigation (PN) intervention versus usual care (UC) on the uptake of colorectal cancer (CRC) screening among females living in Midwest rural areas. METHODS: As part of a larger study, 663 females (ages 50-74) living in rural Indiana and Ohio and not up-to-date (UTD) with CRC screening at baseline were randomized to one of three study groups...

BACKGROUND: Post-fecal immunochemical test (FIT) colonoscopy represents a setting with an enriched prevalence of advanced adenomas. Due to an expected higher risk of colorectal cancer (CRC), postpolypectomy surveillance is recommended, generating a substantially increased load on endoscopy services. The aim of our study was to investigate postpolypectomy CRC risk in a screening population of FIT+ subjects after resection of low-risk adenomas (LRAs) or high-risk adenomas (HRAs). METHODS: We retrieved data from a cohort of patients undergoing postpolypectomy surveillance within a FIT-based CRC screening program in Italy between 2002 and 2017 and followed-up to December 2021...

INTRODUCTION: Modeling supporting recommendations for colonoscopy and stool-based colorectal cancer (CRC) screening tests assumes 100% sequential participant adherence. The impact of observed adherence on the long-term effectiveness of screening is unknown. We evaluated the effectiveness of a program of screening-colonoscopy every ten years versus annual high-sensitivity guaiac-based fecal occult blood testing (HSgFOBT) using observed sequential adherence data. METHODS: MIcrosimulation SCreening ANalysis (MISCAN) model using observed sequential screening adherence, HSgFOBT positivity, and diagnostic-colonoscopy adherence in HSgFOBT-positive individuals from the National Colonoscopy Study (NCS; single screening-colonoscopy versus ≥4 HSgFOBT sequential rounds)...

Background Screening colonoscopy detects precancerous polyps, which when resected, prevents colon cancer. Recommendations for surveillance colonoscopy after polypectomy are based on the U.S. Multi-Society Task Force guidelines (USMSTF). Aim to examine provider recommendations based on 2012 and 2020 USMSTF guidelines. Methods A prospective analysis was performed to examine provider recommendations for index screening and surveillance colonoscopy from March 2022 to January 2023. Procedures with unknown histology or unsatisfactory bowel preparation were excluded...

During the COVID-19 pandemic, health systems, including federally qualified health centers (FQHCs), experienced disruptions in colorectal cancer (CRC) screening. National organizations called for greater use of at-home stool-based testing followed by colonoscopy for those with abnormal test results to limit (in-person) colonoscopy exams to people with acute symptoms, or who were high-risk. This 'stool-test-first' strategy may also be useful for adults with low-risk adenomas who are due for surveillance colonoscopy...

INTRODUCTION: Adenoma detection rate (ADR) is an accepted benchmark for screening colonoscopy. Factors driving ADR and its relationship with sessile serrated lesions detection rate (SSLDR) over time remain unclear. We aim to explore patient, physician, and procedural influences on ADR and SSLDR trends. METHODS: Using a large healthcare system in northern California from January 2010 to December 2020, a total of 146,818 screening colonoscopies performed by 33 endoscopists were included...

The incidence and mortality of colorectal cancer (CRC) have decreased through regular screening colonoscopy, surveillance, and endoscopic treatment. However, CRC can still be diagnosed after negative colonoscopy. Such CRC is called interval CRC and accounts for 1.8-9.0% of all CRC cases. Most cases of interval CRC originate from missed lesions and incompletely resected lesions. Interval CRC can be minimized by improving the quality of colonoscopy. This has led to a growing interest in and demand for high-quality colonoscopy...

BACKGROUND: Data on post-colonoscopy colorectal cancers (PCCRCs) after fecal occult blood test (FOBT)-positive colonoscopies is scarce (guaiac-based (gFOBT) or fecal immunochemical test (FIT)). AIMS: Evaluate the prevalence and characteristics of PCCRCs in the French gFOBT CRC screening program. METHODS: Retrospective population-based cohort study of all gFOBT-positive colonoscopies performed among individuals aged 50-74 between 2003 and 2014 within the CRC screening program organized in the Haut-Rhin (Alsace, France)...

BACKGROUND: Primary care physicians (PCP) play a key role in offering colorectal cancer (CRC) screenings, particularly amongst underserved populations. Given potential delays in or omission of CRC screening in the absence of a PCP, we aimed to determine stage of CRC at diagnosis in an underserved population. METHODS: A retrospective chart review was conducted at two Los Angeles County safety-net hospitals. Inclusion criteria were a CRC diagnosis between 2018 and 2021 and age between 50 and 75 years at diagnosis time...

Patients with inflammatory bowel disease (IBD) have increased risk of colorectal cancer (CRC). The risk for CRC is positively correlated to the duration of disease, extent of colonic involvement, and severity of inflammation. After 8 to 10 years of IBD diagnosis, the risk for CRC rises substantially and screening colonoscopy is recommended. Surveillance colonoscopy interval ranges from 1 to 5 years depending on patient and disease-specific risk factors. IBD patients with high risk factors such as having concomitant primary sclerosing cholangitis, moderate-to-severe inflammation, first-degree relative with CRC at early age, or history of invisible dysplasia or high-risk visible dysplasia should undergo surveillance colonoscopy in 1 year...

AIMS: This review aims to summarize the different colorectal cancer guidelines for average-risk and high-risk individuals from various countries. METHODS: A comprehensive literature search regarding guidelines, consensus recommendations, or position statements about colorectal cancer screening published within the last 10 years (1st January 2012 to 27th August 2022), was performed at EBSCOhost, JSTOR, PubMed, ProQuest, SAGE, and ScienceDirect. RESULTS: A total of 18 guidelines were included in this review...

BACKGROUND: Post-colonoscopy colorectal cancers (PCCRCs) decrease the effect of colorectal cancer (CRC) screening programs. To enable PCCRC incidence reduction in the long-term, we classified PCCRCs diagnosed after colonoscopies performed in a fecal immunochemical test (FIT)-based screening program. METHODS: PCCRCs diagnosed after colonoscopies performed between 2014-2016 for a positive FIT in the Dutch CRC screening program were included. PCCRCs were categorized according to the World Endoscopy Organization consensus statement into (a) interval PCCRC (diagnosed before the recommended surveillance); (b) non-interval type A (diagnosed at the recommended surveillance interval); (c) non-interval type B (diagnosed after the recommended surveillance interval); or (d) non-interval type C (diagnosed after the intended recommended surveillance interval, with surveillance not implemented owing to co-morbidity)...

BACKGROUND: Clinical guidelines recommend that patients with long-standing ulcerative colitis (UC) should undergo periodic surveillance colonoscopy. However, the cost and clinical value of performing annual colonoscopy among high-risk patient populations is largely unknown in the Middle East. Therefore, this study aimed to examine the cost and consequence of annual colonoscopy among high-risk UC patients in Saudi Arabia. METHODS: A retrospective cohort study was conducted on UC patients who had UC for ≥ 8 years or had primary sclerosing cholangitis (PSC) at any time during their disease,and underwent colonoscopy surveillance between 2010 and 2021 at a university-affiliated tertiary care center...

BACKGROUND AND AIMS: Colorectal cancer (CRC) screening is recommended worldwide, while gastric cancer (GC) screening may also be defendable in some settings. However, adherence rates and factors influencing participation are not well characterized. This study aimed to validate a tool to determine risk perception of CRC and GC and also of endoscopy-related complications. METHODS: A questionnaire in CRC risk perception based on the Health Belief Model was used. Forward/backward translation (English-Portuguese) and cultural adaptation were performed...

OBJECTIVE: To evaluate the effect of telephone instructions on the quality of bowel preparation in patients undergoing colonoscopy. METHODS: Online English databases (PubMed, Web of Science, Cochrane Library, and Embase) were screened for randomized controlled trials on telephone instructions regarding bowel preparation for colonoscopy from inception to April 15, 2022. After data extraction, the Review Manager software was used for meta-analysis. RESULTS: Nine randomized controlled trials with 3,836 patients were included in the meta-analysis...

BACKGROUND: The incidence of early-onset colorectal cancer (CRC) is continuously increasing worldwide. Current guidelines in China recommend average-risk individuals starting CRC screening at age 50. AIMS: To investigate the relationship between the gastric histopathology and colorectal neoplasms to identify CRC risk factors which potentially guide earlier colonoscopy in individuals aged < 50 years. METHODS: A retrospective cross-sectional study was conducted on 8819 patients younger than age 50 who underwent gastroscopy and colonoscopy simultaneously between November 7, 2020 and November 14, 2022...
