BACKGROUND AND AIMS: Adenoma detection rate (ADR) is the most validated quality indicator for colonoscopy. Calculating ADR may not yield information in regards to advanced adenoma detection rate (advanced ADR). In addition, calculating ADR for individual endoscopists cannot distinguish between those who find only one versus more than one adenoma per colonoscopy. Several novel quality indictors were recently proposed to ensure adequate assessment of quality during colonoscopy. Our study aims to determine the correlation between ADR and novel quality indicators...

Background: Colorectal cancer is one of the leading causes of cancer deaths worldwide. The detection and removal of the precursors to colorectal cancer, adenomatous polyps, is the key for screening. The aim of this study was to develop a clinically scalable (high throughput, low cost, and high sensitivity) mass spectrometry (MS)-based urine metabolomic test for the detection of adenomatous polyps. Methods: Prospective urine and stool samples were collected from 685 participants enrolled in a colorectal cancer screening program to undergo colonoscopy examination...

Colonoscopy is the gold standard for colorectal cancer prevention; however, it is still an imperfect modality. Precancerous lesions can be lost during screening examinations, thus increasing the risk of interval cancer. A variety of factors either patient-, or endoscopist dependent or even the procedure itself may contribute to loss of lesions. Sophisticated modalities including advanced technology endoscopes and add-on devices have been developed in an effort to eliminate colonoscopy's drawbacks and maximize its ability to detect potentially culprit polyps...

As the worldwide incidence of cancer continuously rises, one of the measures to reduce mortality is early diagnosis while the disease is still curable. Colonoscopy screening and PAP-smears are worthwhile examples illustrating the impact of early diagnosis on mortality. Ovarian cancer is the first cause of mortality by gynecological cancers in Switzerland (incidence of 600 new cases / year), mostly diagnosed at advanced stages with a poor prognosis. Could surveillance measures improve survival ? Three large-scale randomized control trials failed to show mortality reduction from ovarian cancer with the methods currently available...

INTRODUCTION: Incidence of well-differentiated neuroendocrine tumors (NETs) of the colon and rectum is increasing and is now approximately 1 per 100,000 in the US. NETs are either well-differentiated (indolent) or poorly differentiated (aggressive). The majority of these tumors are found incidentally during screening colonoscopies and rarely are associated with symptoms of hormonal syndrome, even during the advanced stage. Metastatic well-differentiated NETs of the colon and rectum are incurable, hard to treat, and associated with a poor prognosis and survival rates similar to colorectal adenocarcinoma survival...

Endoscopic submucosal dissection (ESD) is a groundbreaking treatment for tumors adjacent to the appendiceal orifice that are difficult to remove by conventional endoscopic mucosal resection, and successful cases are increasingly reported. However, little is known about the subsequent complications, especially long-term complications. A female in her early 70s with a 15-mm cecal tumor adjacent to the appendiceal orifice - discovered incidentally during a screening colonoscopy - underwent hybrid ESD of the lesion...

A population-based program promoting the Fecal Occult Blood Test (FOBT) for colorectal cancer screening was introduced in 2008 in Ontario, Canada, where opportunistic screening with colonoscopy had been increasing in frequency. We evaluated the impact of the program on income and immigration-related disparities in screening. We used linked administrative data to calculate colorectal cancer screening rates for eligible Ontarians in each year between 2001/02 (n=2,852,619) and 2013/14 (n=4,139,304). We quantified disparities using an "inequality ratio" of screening rates in the most disadvantaged group relative to the most advantaged group...

BACKGROUND & AIMS: Low activity of natural killer (NK) cells has been associated with increased risk of cancer and has been reported in patients with colorectal cancer (CRC). Activity of NK cells can be measured in a small volume of whole blood by a commercially available test. We investigated whether this test could be used to identify patients with CRC, using findings from colonoscopy as a reference standard. METHODS: We performed an open-label, prospective, cross-sectional study of 872 high-risk subjects (more than 40 years old) screened for CRC by colonoscopy at a university hospital in Montreal, Canada from October 2014 through January 2016...

In the era of precision medicine, efforts are needed to identify and tailor screening recommendations among elevated-risk patients. Individuals younger than 50years are an important target population, as they comprise 15% of colorectal (CRC) cases and often present with more advanced disease than their 50+ counterparts. In this large study, 2470 patients ages 25-49 used a tablet-based program that assessed risks, matched risks with screening guidelines, and generated tailored printed guideline-concordant recommendations for patients and their providers...

BACKGROUND: Screening with faecal occult blood tests reduces colorectal cancer-related mortality; however, age, sex and socioeconomic factors affect screening outcomes and could lead to unequal mortality benefits. The aim of this study was to describe the main outcomes of the population-based Barcelona colorectal cancer screening programme (BCRCSP) by deprivation. METHODS: Retrospective study of the eligible population of the first round of the BCRCSP. Participants' postal addresses were linked with the MEDEA database to obtain the deprivation quintiles (Dq)...

BACKGROUND AND AIMS: Few prior reports exist that address the appropriate colonoscopy surveillance interval for individuals <50 years old. We compared the risk of metachronous neoplasia between younger (20-49 years) and older (50-54 years) cohorts. METHODS: This multicenter retrospective cohort study compared the incidence of metachronous neoplasia in younger and older cohorts according to baseline risk stratification. Subjects were eligible if they underwent their first colonoscopy between June 2006 and May 2010, and had at least one or more surveillance colonoscopy up to June 2015...

Colonoscopy is a common and routine procedure performed in the United States, most commonly performed for screening of colorectal cancer. Although colonoscopy is considered a safe procedure, it is associated with complications including intestinal hemorrhage and perforation. Splenic trauma, such as laceration or even complete rupture is a rarely reported, but potentially fatal complication if undetected. We present a case of splenic laceration with subcapsular hematoma status post routine colonoscopy. Fortunately, patient was able to be managed medically, without further operative intervention...

Background and study aims Up to 25 % colorectal adenomas are missed during colonoscopy. The aim of this study was to investigate whether the endocuff could improve polyp detection in an organized bowel cancer screening program (BCSP). Patients and methods This parallel group, single-blinded, randomized controlled trial included patients with positive fecal occult blood test (FOBT) who were attending for BCSP colonoscopy. The primary outcome was the number of polyps per patient. Secondary outcomes included the number of adenomas per patient, adenoma and polyp detection rates, and withdrawal times...

BACKGROUND & AIM: Colonic diverticulosis has been reported to be associated with low-grade mucosal inflammation possibly leading to chronic gastrointestinal symptoms. However, there is poor evidence for this association. We aimed to determine whether colonic diverticula are associated with mucosal inflammation and whether diverticula are associated with chronic gastrointestinal symptoms. We explored whether inflammation was present among symptomatic participants with and without diverticula...

This document updates the colorectal cancer (CRC) screening recommendations of the U.S. Multi-Society Task Force of Colorectal Cancer (MSTF), which represents the American College of Gastroenterology, the American Gastroenterological Association, and The American Society for Gastrointestinal Endoscopy. CRC screening tests are ranked in 3 tiers based on performance features, costs, and practical considerations. The first-tier tests are colonoscopy every 10 years and annual fecal immunochemical test (FIT). Colonoscopy and FIT are recommended as the cornerstones of screening regardless of how screening is offered...

A 64-year-old woman was found dead at home after undergoing a screening colonoscopy. At autopsy, 1.9 L of blood was discovered within her abdominal cavity. The only major abnormality was nontraumatic avulsion of the splenic capsule. This was the only identifiable abnormality capable of causing the severe hemoperitoneum and demise of the patient. Although rare, splenic capsule avulsion is a recognized complication of colonoscopy. Many have theorized that it results from excessive traction on the splenocolic ligament resulting in a tear of the splenic capsule...
