Background and study aims  Treatment of colorectal polyps in patients undergoing permanent anticoagulation is associated with a significantly increased risk of peri-interventional bleeding. This specifically applies to polyps > 1 cm where endoscopic full-thickness resection (EFTR) with the full-thickness-resection device (FTRD) can be taken into consideration as an alternative approach to classical snare polypectomy. For these indications, EFTR appears to be superior to conventional techniques especially in terms of sufficient hemostasis due to the mechanical tissue compression achieved by the FTRD's integrated Over-The-Scope Clip (OTSC)...

Background and study aims Colonoscopic polypectomy reduces colorectal cancer incidence, but is associated with complications including post-polypectomy bleeding (PPB). PPB ranges in severity from minor to life-threatening, making interpretation and comparison difficult. No previous studies have examined PPB rate according to a standardized severity grading system. We aimed to determine the PPB rate stratified by severity grading, explore factors that contribute to PPB severity grading, and describe PPB management...

A 78-year-old woman with hypertension had a positive fecal immunochemical test and underwent colonoscopy, which revealed a 4 mm sessile polyp (Paris type; 0-Is) in the transverse colon. Based on low magnification colonoscopy with narrow band imaging, the polyp was Type 2 according to the NBI International Colorectal Endoscopic classification, diagnosed as an adenoma, and then resected via cold snare polypectomy (CSP). Five days after CSP, she complained of right-sided abdominal pain. Abdominal CT showed focal wall thickening of the transverse colon and focal infiltration of tissues surrounding the transverse colon...

Colonoscopy is one of the most commonly performed endoscopic procedures. It is the gold standard examination for work-up of colonic symptoms, for follow-up of positive colorectal cancer screening tests and for detection and removal of neoplastic polyps. Colonoscopy is a complex and invasive procedure with a potential not only for colorectal cancer prevention, but also for serious complications. Numerous factors may affect the balance of benefit versus harm of colonoscopy, including the performance of the endoscopist...

BACKGROUND AND STUDY AIMS:  Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis. PATIENTS AND METHODS:  This was a retrospective cohort study conducted in a single municipal hospital...

BACKGROUND/AIMS: Colonoscopic polypectomy is the best diagnostic and therapeutic tool to detect and prevent colorectal neoplasms. However, previous studies have reported that 17% to 28% of colorectal polyps are missed during colonoscopy. We investigated the miss rate of neoplastic polyps and the factors associated with missed polyps from quality-adjusted consecutive colonoscopies. METHODS: We reviewed the medical records of patients who were found to have colorectal polyps at a medical examination center of the Kangbuk Samsung Hospital between March 2012 and February 2013...

BACKGROUND AND AIMS: Small colorectal polyps are encountered frequently and may be incompletely removed during colonoscopy. The optimal technique for removal of small colorectal polyps is uncertain. The aim of this study was to compare the incomplete resection rate (IRR) by using EMR or cold snare polypectomy (CSP) for the removal of small adenomatous polyps. METHODS: This was a prospective randomized controlled study from a tertiary-care referral center. A total of 358 patients who satisfied the inclusion criteria (polyp sized 6-9 mm) were randomized to the EMR (n =179) and CSP (n =179) groups, and their polyps were treated with conventional EMR or CSP, respectively...

BACKGROUND: For some patients, positive cancer screening test results can be a stressful experience that can affect future screening compliance and increase the use of health care services unrelated to medically indicated follow-up. METHODS: Among 483,216 individuals aged 50 to 75 years who completed a fecal immunochemical test to screen for colorectal cancer at a large integrated health care setting between 2007 and 2011, the authors evaluated whether a positive test was associated with a net change in outpatient primary care visit use within the year after screening...

BACKGROUND: Evidence regarding the benefit of therapy to prevent the post-polypectomy recurrence of colorectal adenoma is limited. Endoscopic recurrence is the main outcome according to an evaluation of trials involving recurrence prevention. AIM: To estimate the recurrence rates of post-polypectomy colorectal adenoma in placebo-controlled arms of randomized clinical trials and to identify the prognostic factors influencing these rates. METHODS: We combined data from all randomized controlled trials evaluating therapies for colorectal adenoma using placebo from 1988 to 2016...

Endoscopic surveillance after colorectal polypectomy These guidelines for endoscopic surveillance after colorectal polypectomy are based on the recommendations published by European Society of Gastrointestinal Endoscopy (ESGE) in 2013. A precondition for the guidelines is that patients have undergone a high-quality colonoscopy, including complete removal and histopathological evaluation of all detected neoplastic lesions. Current research has made it possible to stratify patients into a low-risk and a high-risk group in terms of metachronous cancer...
