Cuff-assisted versus cap-assisted colonoscopy for adenoma detection: results of a randomized study.

 The adenoma detection rate (ADR) is the most important marker of colonoscopy quality. Devices to improve adenoma detection have been developed, such as the Endocuff and transparent cap. The aim of the current study was to examine whether there was a difference in ADR between Endocuff-assisted (EAC) and cap-assisted colonoscopy (CAC).

Endocuff-assisted colonoscopy for surveillance of serrated polyposis syndrome: a multicenter randomized controlled trial.

 Serrated polyposis syndrome (SPS) is a condition with high risk for colorectal cancer. The Endocuff device has been shown to increase adenoma detection in the general and screening population. We aimed to ascertain whether Endocuff-assisted colonoscopy increases detection of serrated lesions in comparison with standard colonoscopy during the surveillance of patients with SPS.  METHODS:  In a multicenter randomized controlled study, patients who met SPS criteria I and/or III under surveillance (previo...

Endocuff Vision Reduces Inspection Time Without Decreasing Lesion Detection in a Randomized Colonoscopy Trial.

Mucosal exposure devices improve detection of lesions during colonoscopy and have reduced examination times in uncontrolled studies. We performed a randomized trial of Endocuff Vision vs standard colonoscopy to compare differences in withdrawal time (the primary end point). We proposed that Endocuff Vision would allow complete mucosal inspection in a shorter time without impairing lesion detection.

Proposal of high-risk adenoma detection rate as an impactful, complementary quality indicator of colonoscopy.

Adenoma detection rate (ADR), a validated quality indicator (QI) of colonoscopy, does not take into account risk stratification of adenomas. Low-risk adenomas are not associated with a significantly increased risk of future colorectal cancer (CRC). On the other hand, high-risk adenomas (HRA) are associated with up to six fold higher risk of future CRC. Therefore, HRA detection rate (HR-ADR) as a QI in addition to ADR may further enhance the efficacy of screening colonoscopy. Our aim was to calculate ADR and...

CD204-Positive Tumor-associated Macrophages Relate to Malignant Transformation of Colorectal Adenoma.

Colorectal adenoma is well known as a precursor lesion of colorectal adenocarcinoma (ADC). We recently reported the significance of CD204 (+) tumor-associated macrophages (TAMs), a vital component of the tumor microenvironment, in the carcinoma development of gastric adenoma. The aim of the present study was to clarify the roles of TAM in the malignant transformation of colorectal adenoma.

Detection Rate of Colorectal Cancer or Precancer Adenoma by Colonoscopy After 1, 2, or 3 Positive Results via Fecal Immunochemical Testing.

Single-vial fecal immunochemical testing (FIT) is an accepted method of colorectal cancer (CRC) screening. The available 3-vial FIT data set allows for comparison of colonoscopy results using various screening methods.

Yield of repeat colonoscopy in asymptomatic individuals with a positive fecal immunochemical test and recent colonoscopy.

A fecal immunochemical test (FIT) is often repeated annually, even after a recent colonoscopy. However, there are no published data on the proper approach to FIT-positive patients after a recent colonoscopy. We compared colorectal cancer (CRC) and advanced colorectal neoplasia (ACRN) prevalence based on the interval since the last colonoscopy.

Adenoma detection rates in colonoscopies for positive fecal immunochemical tests versus direct screening colonoscopies.

Recent guidelines propose higher adenoma detection rate (ADR) benchmarks for colonoscopies performed for positive fecal immunochemical tests (FIT), but this is based on low quality evidence. We aimed to compare ADR, advanced ADR (AADR), and number of adenoma per colonoscopy (APC) in direct screening colonoscopy (DSC) versus FIT positive colonoscopy (FITC) in a multicenter Asia Pacific cohort to justify differential targets.

The "Difficult" Colorectal Polyps and Adenomas: Practical Aspects.

Colonoscopy is the gold standard for adenoma detection. All endoscopists who perform colonoscopy must by mandate be skilled to perform polypectomy. However, there are significant differences between endoscopists in terms of the polyp detection rate and in the effectiveness of polypectomy.

Circulating inflammation markers and colorectal adenoma risk.

Inflammation is a driver of colorectal neoplasia; however, what particular inflammatory processes play a role in early carcinogenesis are unclear. We compared serum levels of 78 inflammation markers between 171 pathologically confirmed colorectal adenoma cases (including 48 incident cases) and 344 controls within the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. We used weighted multivariable logistic regression to compute odds ratio (OR) and 95% confidence interval (CI). We found 14 marke...

Decreased Colorectal Adenoma Risk after Helicobacter pylori Eradication: A Retrospective Cohort Study.

Helicobacter pylori (H. pylori) infection is associated with colorectal adenoma and confers a 1.3- to 2.26-fold increased risk. We evaluated the association between H. pylori and progression of colorectal adenoma.

Screening Colonoscopy in Patients Evaluated for Liver Transplant: Look before You Leap.

We read with interest the paper by Oey and colleagues. While the argument for caution regarding the safety of colonoscopy in patients evaluated for liver transplant(LT) has merit, the low yield of colorectal cancer (CRC) in their study is not surprising considering that majority of patients were average risk. However, low yield of CRC is a soft argument against screening colonoscopy in pre-LT patients because evidence suggests that the risk of advanced adenoma (AA) and CRC significantly increases post-LT. T...

Right-Sided Location Not Associated with Missed Colorectal Adenomas in an Individual-Level Reanalysis of Tandem Colonoscopy Studies.

Interval cancers occur more frequently in the right colon. One reason could be that right-sided adenomas are frequently missed in colonoscopy examinations. We reanalyzed data from tandem colonoscopies to assess adenoma miss rates in relation to location and other factors.

Patient-Initiated Colonoscopy Scheduling Effectively Increases Colorectal Cancer Screening Adherence.

We identified patients without medical record evidence of up-to-date colorectal cancer (CRC) screening and sent an invitation letter to self-schedule a colonoscopy without requiring prior primary care or gastroenterologist consultation. The aim of the study was to evaluate the response rate to the letter and factors associated with colonoscopy completion.

Metagenomic analyses of the gut microbiota associated with colorectal adenoma.

Recent studies have suggested an association between certain members of the Fusobacterium genus, especially F. nucleatum, and the progression of advanced colorectal carcinoma (CRC). We assessed such an association of the gut microbiota in Japanese patients with colorectal adenoma (CRA) or intramucosal CRC using colonoscopy aspirates. We analyzed samples from 81 Japanese patients, including 47 CRA and 24 intramucosal CRC patients, and 10 healthy subjects. Metagenomic analysis of the V3-V4 region of the 16S r...

Disagreement between high confidence endoscopic adenoma prediction and histopathological diagnosis in colonic lesions ≤ 3 mm in size.

 Diminutive colorectal polyps resected during colonoscopy are sometimes histologically interpreted as normal tissue. The aim of this observational study was to explore whether errors in specimen handling or processing account in part for polyps ≤ 3 mm in size being interpreted as normal tissue by pathology when they were considered high confidence adenomas by an experienced endoscopist at colonoscopy.

Effects of L-Menthol and Carbon Dioxide on the Adenoma Detection Rate during Colonoscopy: L-Menthol and Carbon Dioxide on Colonoscopy.

We examined the efficacy of the combined use of L-menthol spraying (L-mentholS) as an antispasmodic agent and carbon dioxide insufflation (CO2I) on the adenoma detection rate (ADR) in a prospective, single-center trial with a 2 × 2 factorial design.

Upregulation of Fibroblast Growth Factor 19 Is Associated with the Initiation of Colorectal Adenoma.

Fibroblast growth factor 19 (FGF19) promotes tumor growth in various types of cancer, but its function has not been investigated in the context of colorectal adenoma. Here, we report that FGF19 expression was greater in colorectal adenoma than in normal tissues, as measured by an enzyme-linked immunosorbent assay, quantitative reverse-transcription PCR and immunohistochemistry. FGF19 expression was also elevated in a subset of human colon cancer cell lines. Moreover, FGF receptor 4 (FGFR4), the cognate rece...

Open Access Colonoscopy for Colorectal Cancer Prevention: An Evaluation of Appropriateness and Quality.

Open access colonoscopy (OAC) has gained widespread acceptance and has the potential to increase colorectal cancer (CRC) screening. However, there is little data evaluating its appropriateness for CRC prevention.

Risk of post-colonoscopy colorectal cancer in Denmark: time trends and comparison with Sweden and the English National Health Service.

 The post-colonoscopy colorectal cancer (PCCRC) rate is a key quality indicator for colonoscopy. Previously published PCCRC rates have been difficult to compare owing to differences in methodology. The primary aim of this study was to compare Danish PCCRC rates internationally and to calculate Danish PCCRC rates using the World Endoscopy Organization (WEO) consensus method for future comparison. The secondary aim was to identify factors associated with PCCRC.

Colorectal Cancer Screening and Surveillance Colonoscopy in Older Adults.

The purpose of this chapter is to highlight current recommendations regarding colorectal cancer (CRC) screening and post-polypectomy surveillance colonoscopy in older adults and to review the available literature in order to help inform decision-making in this age group.

Effectiveness of a short message service intervention to motivate people with positive results in preliminary colorectal cancer screening to undergo colonoscopy: A randomized controlled trial.

Colonoscopy adherence among populations at high risk for colorectal cancer (CRC) is crucial for the early diagnosis and treatment of CRC, but the adherence rate has been found to be poor. A short message service (SMS) is effective in promoting cancer screening, but its effectiveness in promoting colonoscopy among populations at high risk for CRC has not been well studied.

Data quality and colonoscopy performance indicators in the prevalent round of a FIT-based colorectal cancer screening program.

From the prevalent round of the Danish FIT-based colorectal cancer (CRC) screening program, we aimed (i) to evaluate the quality of recorded data and (ii) to characterize the colonoscopies by measuring variation in performance indicators between colonoscopists and assessing the ratio between adenoma detection rate (ADR) and polyp detection rate (PDR).

Routine Colonoscopy After Acute Diverticulitis: is it Warranted?

Recent evidence suggests routine colonoscopy after acute diverticulitis is not necessary but remains debatable. The aim of this study was to investigate the incidence of follow-up colonoscopic finding of adenoma, advanced neoplastic lesion, and adenocarcinoma after diverticulitis.

Post-colonoscopy colorectal cancers identified by probabilistic and deterministic linkage: results in an Australian prospective cohort.

Post-colonoscopy colorectal cancers (PCCRCs) are recognised as a critical quality indicator. Benchmarking of PCCRC rate has been hampered by the strong influence of different definitions and methodologies. We adopted a rigorous methodology with high-detail individual data to determine PCCRC rates in a prospective cohort representing a single jurisdiction.
