Impact of real-time automatic quality control system on colorectal polyp and adenoma detection: a prospective randomized controlled study (with video)

Quality control can decrease variations among colonoscopists ’ performance and improve colonoscopy effectiveness to prevent colorectal cancers. Unfortunately, routine quality control is difficult to carry out because of lacking a practical method. The aim of this study was to develop an automatic quality control system (AQCS) and assess whether it could imp rove polyp and adenoma detection in clinical practice.

Overall, 161 participants who were under patronage of a local relief foundation and referred to the endoscopy ward of Razi Hospital affiliated to the Guilan University of Medical Sciences. These patients have been aged more than 50 or more than 40 years with history of colorectal cancer in...

AbstractBackgroundFactors associated with interval colorectal cancer (CRC) development in the inflammatory bowel disease (IBD) population remain unclear.AimsAmong a cohort of patients with interval CRC, we aimed to evaluate IBD characteristics, colonoscopy quality indicators, and surveillance guideline adherence.MethodsWe performed a retrospective review of IBD- and non-IBD-associated interval CRCs diagnosed between January 2007 and December 2014 within a large US healthcare system. We evaluated risk factors for CRC among patients with IBD. We assessed adherence to surveillance guidelines according to the American Society ...

Colonoscopic polypectomy is fundamental to effective prevention of colorectal cancer. Polypectomy reduces colorectal cancer incidence and mortality by altering the natural history and progression of precancerous precursor polyps. Epidemiologic data from the United States, where colorectal cancer rates have been steadily declining in parallel with screening efforts, provide indisputable evidence about the effectiveness of polypectomy. Randomized controlled trials of fecal occult blood tests and flexible sigmoidoscopy, and observational colonoscopy studies, provide additional support. Longitudinal studies have shown variable...

ConclusionsOur results suggest that there is not a strong association between SSA/Ps and subsequent advanced colorectal neoplasia during the 5  years following SSA/P removal.

Once it became clear that most colorectal cancers developed from premalignant colon polyps, screening colonoscopy with removal of these polyps became the focus of colon cancer prevention with demonstrable effectiveness. The brilliant simplicity of the flexible cautery snare quickly became the standard method for polypectomy, and the use of partial colon resections to remove precancerous colon polyps plummeted. As colonoscopy evolved with an emphasis on higher detection of adenomas and identification of subtle flat colon lesions such as sessile serrated adenomas, the need for improved polypectomy techniques has become obvious.

A key to successful colorectal cancer (CRC) prevention is complete colon polyp removal. The quality of colonoscopy is currently defined by how well we identify neoplastic lesions, as measured by adenoma detection rates (ADRs). A higher ADR correlates with lower rates of interval colon cancers.1 However, the completeness and skills of resection are important factors as well, but they are not current quality metrics and would be an onerous task to measure in daily practice.

ConclusionsTraining the discriminator and generator of the model on real images, we show that our model performs implicit domain adaptation, which is a key step towards bridging the gap between synthetic and real data. Importantly, we demonstrate the feasibility of training a single model to predict depth from both synthetic and real images without the need for explicit, unsupervised transformer networks mapping between the domains of synthetic and real data.

The objective of this study was to evaluate the relationship between the polyp detection rate and its influence on post-colonoscopy colorectal cancer rate. PATIENTS AND METHODS: in this study, 12,482 colonoscopies conducted by 14 endoscopists were analyzed. The polyp detection rate was calculated for each endoscopist. Endoscopists were grouped into quartiles (Q1, Q2, Q3, and Q4), from lowest to highest polyp detection rate, in order to evaluate whether there were any differences in the development of post-colonoscopy colorectal cancer. RESULTS: the lowest polyp detection rate was 20.66% and the highest was 52.16%, ...

Conclusion Despite the different criteria used to determine surveillance after serrated polyp resection, most individuals are recommended identical colonoscopy surveillance intervals whether following the ESGE or US-MSTF guidelines. This suggests that surveillance recommendations do not need to consider the serrated polyp subtype.

ConclusionColon polyps are incompletely resected in a small but potentially significant percentage of cases. IRR are similar with the use of cold jumbo forceps and cold snare. Use of cold jumbo forceps may result in more successful tissue retrieval as compared to cold snare.
