Serrated polyposis syndrome (SPS) is associated with an increased colorectal cancer (CRC) risk, although the magnitude of risk remains uncertain. Whereas intensive endoscopic surveillance for CRC prevention advised, predictors that identify patients who have high remain unknown. We performed a multicentre nationwide study aimed at describing in SPS and identifying clinicopathological independently CRC.From March 2013 through September 2014, were retrospectively recruited 18 Spanish centres....
The role of computer-aided detection in identifying advanced colorectal neoplasia is unknown.To evaluate the contribution to colonoscopic neoplasias as well adenomas, serrated polyps, and nonpolypoid right-sided lesions.Multicenter, parallel, randomized controlled trial. (ClinicalTrials.gov: NCT04673136).Spanish cancer screening program.3213 persons with a positive fecal immunochemical test.Enrollees were randomly assigned colonoscopy or without detection.Advanced was defined adenoma and/or...
Background and aims Serrated polyposis syndrome (SPS) is associated with an increased risk of colorectal cancer (CRC). International guidelines recommend surveillance intervals 1–2 years. However, yearly likely leads to overtreatment for many. We prospectively assessed a protocol aiming safely reduce the burden colonoscopies. Methods Between 2013 2018, we enrolled SPS patients from nine Dutch Spanish hospitals. Patients were surveilled using appointing either 1-year or 2-year interval after...
Main recommendations Endoscopic mucosal resection (EMR) is the standard of care for complete removal large (≥ 10 mm) nonpedunculated colorectal polyps (LNPCPs). Increased detection LNPCPs owing to screening colonoscopy, plus high observed rates incomplete and need surgery call a standardized approach training in EMR. 1 Trainees EMR should have achieved basic competence diagnostic < 10-mm polypectomy, pedunculated common methods gastrointestinal endoscopic hemostasis. The role formal...
Backgrounds and Aims: Cold snare EMR (CS-EMR) in large flat non-pedunculated colonic lesions (LFNPCLs) is an alternative to the standard procedure with a better safety profile, but scientific evidence on its efficacy unavailable. Primary objective: To compare recurrence rate between two techniques at six months. Secondary objectives: comparison of profile several procedure-related outcomes. Patients methods: This was noninferiority, multicentric, open-label, randomized controlled trial...
BACKGROUND : Colorectal polypectomy is operator dependent, with variable rates of complete resection. The currently available assessment tools do not provide specific competency-based evaluation provider technique. We aimed to validate the Global Polypectomy Assessment Tool (GPAT), a novel competency tool for colorectal polypectomy. METHODS GPAT was derived from ESGE Curriculum Training in endoscopic mucosal resection colon. Members curriculum taskforce plus three invited trainees and...
Background and study aims Serrated polyposis syndrome (SPS) is a high risk condition for colorectal cancer (CRC). Surveillance strategies patients with serrated lesions remain controversial. We aimed to evaluate diagnostic strategy detect SPS consistently during reassessment colonoscopy in proximal lesions. Methods This was retrospective of all individuals from fecal immunochemical test (FIT)-based CRC screening program (2010 - 2013) one or more ≥ 5 mm the sigmoid colon on baseline...
Abstract Background Serrated polyposis syndrome (SPS) has been associated with an increased risk of colorectal cancer (CRC). Accordingly, intensive surveillance annual colonoscopy is advised. The aim this multicenter study was to describe the advanced lesions in SPS patients undergoing surveillance, and identify factors that could guide prevention strategy. Methods From March 2013 April 2015, 296 who fulfilled criteria I and/or III for were retrospectively recruited at 18 centers. We...
Objective Despite regular colonoscopy surveillance, colorectal cancers still occur in patients with Lynch syndrome. Thus, detection of all relevant precancerous lesions remains very important. The present study investigates Linked Colour imaging (LCI), an image-enhancing technique, as compared high-definition white light endoscopy (HD-WLE) for the polyps this patient group. Design This prospective, randomised controlled trial was performed by 22 experienced endoscopists from eight centres...
Background and study aims Colorectal cancer (CRC) risk after a positive fecal immunochemical test (FIT) negative colonoscopy is unknown. We aimed to ascertain the cumulative incidence of post-colonoscopy colorectal (PCCRC) manifestation other lesions that could explain positivity in individuals with population screening program. Patients method Observational participants from first round CRC program (2010 - 2012) positive-FIT (≥ 20 μg/g feces) (without neoplasia). A 42- 76-month follow-up...
Abstract Background Individuals with a non-syndromic family history of colorectal cancer are known to have an increased risk. There is opportunity prevent early-onset (age less than 50 years) (EOCRC) in this population. The aim was explore the proportion EOCRC that preventable due cancer. Methods This retrospective multicentre European study patients non-hereditary EOCRC. impact Society Gastrointestinal Endoscopy (ESGE), U.S. Multi-Society Task Force (USMSTF), and National Comprehensive...
