Polyp Detection Rate Correlates Strongly with Adenoma Detection Rate in Trainee Endoscopists
Digestive Diseases and Sciences, 2020Co-Authors: Sandy Ng, Aditya K. Sreenivasan, Jillian Pecoriello, Peter S. LiangAbstract:Background The adenoma Detection Rate (ADR) is a widely accepted quality benchmark for screening colonoscopy but can be burdensome to calculate. Previous studies have shown good correlation between polyp Detection Rate (PDR) and ADR, but this has not been validated in trainees. Additionally, the correlation between PDR and Detection Rates for sessile serRated polyps (SSPDR) and advanced neoplasia (ANDR) is not well studied. Aims We investigated the relationship between PDR and ADR, SSPDR, and ANDR in trainees. Methods We examined 1600 outpatient colonoscopies performed by 24 trainees at a VA hospital from 2014 to 2017. Variables collected included patient demographics, year of fellowship, colonoscopy indication, and endoscopic and histologic findings. We calculated the overall ratios of PDR to ADR, SSPDR, and ANDR to assess the correlation between measured and calculated ADR, SSPDR, and ANDR, which is equivalent to the correlation between PDR and measured ADR, SSPDR, and ANDR. Results The overall PDR, ADR, SSPDR, and ANDR were 72%, 52%, 2%, and 14%. PDR (48%) was highest in the left colon, while ADR (32%) and ANDR (7%) were highest in the right colon ( p

modifiable endoscopic factors that influence the adenoma Detection Rate in colorectal cancer screening colonoscopies
Gastrointestinal Endoscopy, 2013Co-Authors: Rodrigo Jover, Pedro Zapater, Eduardo Polania, Luis Bujanda, Angel Lanas, Jose Antonio Hermo, Joaquin Cubiella, Akiko Ono, Yanira Gonzalezmendez, Antonio PerisAbstract:Background Adenoma Detection Rate (ADR) has become the most important quality indicator for colonoscopy. Objective The aim of this study was to investigate which modifiable factors, directly related to the endoscopic procedure, influenced the ADR in screening colonoscopies. Design Observational, nested study. Setting Multicenter, randomized, controlled trials. Patients Asymptomatic people aged 50 to 69 years were eligible for a multicenter, randomized, controlled trial designed to compare colonoscopy and fecal immunochemical testing in colorectal cancer screening. A total of 4539 individuals undergoing a direct screening colonoscopy were included in this study. Intervention Colonoscopy. Main Outcome Measurements Bowel cleansing, sedation, withdrawal time in normal colonoscopies, and cecal intubation were analyzed as possible predictors of adenoma Detection by using logistic regression analysis, adjusted for age and sex. Results In multivariate analysis, after adjustment for age and sex, factors independently related to the ADR were a mean withdrawal time longer than 8 minutes (odds ratio [OR] 1.51; 95% CI, 1.17-1.96) in normal colonoscopies and split preparation (OR 1.26; 95% CI, 1.01-1.57). For advanced adenomas, only withdrawal time maintained statistical significance in the multivariate analysis. For proximal adenomas, withdrawal time and cecal intubation maintained independent statistical significance, whereas only withdrawal time longer than 8 minutes and a Limitations Only endoscopic variables have been analyzed. Conclusion Withdrawal time was the only modifiable factor related to the ADR in colorectal cancer screening colonoscopies associated with an increased Detection Rate of overall, advanced, proximal, and distal adenomas.

SerRated polyp Detection Rate during screening colonoscopy
Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland, 2012Co-Authors: Jennifer Liang, Matthew F. Kalady, K. Appau, James M. ChurchAbstract:Aim The adenoma Detection Rate is an important quality indicator for colonoscopy, but recently, serRated polyps of the large bowel have been recognized as important premalignant lesions. As they are often more difficult to see than adenomas, the Detection Rate of serRated polyps is set to become a more stringent indicator of quality in colonoscopy than adenoma Detection Rate. Here we aim to provide preliminary data on serRated polyp Detection. Method This is a retrospective review of prospectively collected data. Colonoscopies were stratified by one of six colorectal surgeons, each of whom had performed more than 1000 colonoscopies. Exams were sepaRated by indication and the number of patients with at least one adenoma or one serRated polyp recorded. Time of withdrawal in normal examinations was noted. Results Eighteen thousand and three colonoscopies were included. Average completion Rate was 96.3 ± 1.2%. Mean serRated Detection Rate for all examinations was 20.6 ± 4.8% and for screening examinations only was 13.9 ± 5.0%. Corresponding means for adenoma Detection were 31.5 ± 6.7% and 20.7 ± 4.1%, respectively. Simple regression of overall adenoma Detection Rate versus overall serRated Detection Rate was not significant (R = 0.571, P = 0.237), but was significant for screening exams (R = 0.854, P = 0.031). There was a strong relationship between time of withdrawal and serRated Detection Rate (screening, R = 0.908, P = 0.012; overall, R = 0.956, P = 0.003). Conclusion Taking time to withdraw the colonoscope is essential for maximum Detection of serRated polyps. The ability to find adenomas does not necessarily correlate with an ability to find serRated polyps.

Adenoma Detection Rate: The Real Indicator of Quality in Colonoscopy
Diseases of the colon and rectum, 2008Co-Authors: Monica S. Millan, Perita Gross, Elena Manilich, James M. ChurchAbstract:Purpose Completion Rate is the most commonly used index of quality in colonoscopy, and yet a complete examination is not necessarily a good examination. The ability to detect and treat adenomas is an important component of endoscopic skill, because many colonoscopies are performed for this express purpose. Adenoma Detection Rate is rarely reported, although it seems to depend on the time taken for withdrawal. The literature suggests that adenomas should be detected in approximately 25 percent of men and 15 percent of women older than age 50 years. We have reviewed the adenoma Detection Rates of six colorectal surgeons to provide insight into the range of adenoma Detection Rates and the factors that influence them.

Screening Colonoscopy Withdrawal Time Threshold for Adequate Proximal SerRated Polyp Detection Rate
Digestive Diseases and Sciences, 2018Co-Authors: Viral D. Patel, William K. Thompson, Brittany R. Lapin, Jay L. Goldstein, Eugene F. YenAbstract:Introduction For adequate adenoma Detection Rate (ADR), guidelines recommend a mean withdrawal time (MWT) of ≥ 6 min. ADR has been shown to correlate strongly with proximal serRated polyp Detection Rate (PSP-DR), which is another suggested quality measure for screening colonoscopy. However, the impact of directly measured withdrawal time on PSP-DR has not been rigorously studied. We examined the relationship between MWT to ADR and PSP-DR, with the aim of identifying a functional threshold withdrawal time associated with both increased ADR and PSP-DR. Methods This was a retrospective study of endoscopy and pathology data from average-risk screening colonoscopy examinations performed at a large system with six endoscopy laboratories. A natural language processing tool was used to determine polyp location and histology. ADR and PSP-DR were calculated for each endoscopist. MWT was calculated from colonoscopy examinations in which no polyps were resected. Results In total, 31,558 colonoscopy examinations were performed, of which 10,196 were average-risk screening colonoscopy examinations with cecal intubation and adequate prep by 24 gastroenterologists. When assessing the statistical significance of increasing MWT by minute, the first significant time mark for PSP-DR was at 11 min at a Rate of 14.2% ( p = 0.01). There was a significant difference comparing aggregated MWT
