BACKGROUND/AIMS: This study investigated whether the personality traits of endoscopists are associated with the effect of interventions for the improvement of colonoscopy quality.

METHODS: This prospective, multicenter, single-blind study was performed with 13 endoscopists in three health screening centers over a 12-month period. Quality indicators (QIs), including adenoma detection rate (ADR), polyp detection rate (PDR), and withdrawal time, were measured every 3 months. Consecutive interventions for the improvement of colonoscopy quality were conducted every 3 months, which included the personal notification of QIs, the in-group notification of QIs, and finally a targeted "quality education" session. The personality traits of each …

INTRODUCTION: Colonoscopy is currently considered as one of the principal techniques to diagnose the colorectal diseases. Admittedly, qualified bowel preparation before colonoscopy is a premise for high-quality examination. Lower quality bowel preparation might seriously impede visualization of the intestinal mucosa, resulting in missed and misdiagnosed intestinal lesions. Therefore, it is necessary to choose the appropriate oral laxative based on the guarantee of safety and efficacy.

METHODS: This prospective randomized controlled study was conducted to compare lactulose oral solution and polyethylene glycol (PEG) electrolyte powder for bowel preparation using the following indicators: Boston Bowel Preparation Scale, Bowel Bubble Score, detection rate …

Growth Rates And Histopathological Outcomes Of Small (6-9 Mm) Colorectal Polyps Based On Ct Colonography Surveillance And Endoscopic Removal, B Dustin Pooler, David H Kim, Kristina A Matkowskyj, Michael A Newton, Richard B Halberg, William M Grady, Cesare Hassan, Perry J Pickhardt

Student and Faculty Publications

BACKGROUND AND AIMS: The natural history of small polyps is not well established and rests on limited evidence from barium enema studies decades ago. Patients with one or two small polyps (6-9 mm) at screening CT colonography (CTC) are offered CTC surveillance at 3 years but may elect immediate colonoscopy. This practice allows direct observation of the growth of subcentimetre polyps, with histopathological correlation in patients undergoing subsequent polypectomy.

DESIGN: Of 11 165 asymptomatic patients screened by CTC over a period of 16.4 years, 1067 had one or two 6-9 mm polyps detected (with no polyps ≥10 mm). Of these, …

Sessile Serrated Adenomas In The Proximal Colon Are Likely To Be Flat, Large And Occur In Smokers, Tarun Rustagi, Priya Rangasamy, Matthew Myers, Melinda Sanders, Haleh Vaziri, George Y. Wu, John W. Birk, Petr Protiva, Joseph C. Anderson

Aim: To examine the epidemiology and the morphology of the proximal sessile serrated adenomas (SSAs).

Methods: We conducted a retrospective study to identify patients with SSAs using a university-based hospital pathology database query from January 2007 to April 2011. Data collected included: age, gender, ethnicity, body mass index, diabetes, smoking, family history of colorectal cancer, aspirin, and statin use. We collected data on morphology of SSAs including site (proximal or distal), size, and endoscopic appearance (flat or protuberant). We also compared proximal SSAs to proximal tubular adenomas detected during same time period.

Incomplete Polyp Resection During Colonoscopy—Results Of The Complete Adenoma Resection (Care) Study, Heiko Pohl, Amitabh Srivastava, Steve P. Bensen, Peter Anderson, Richard I. Rothstein, Stuart R. Gordon, L Campbell Levy, Arifa Toor, Todd A. Mackenzie, Thomas Rosch, Douglas J. Robertson

Although the adenoma detection rate is used as a measure of colonoscopy quality, there are limited data on the quality of endoscopic resection of detected adenomas. We determined the rate of incompletely resected neoplastic polyps in clinical practice.We performed a prospective study on 1427 patients who underwent colonoscopy at 2 medical centers and had at least 1 nonpedunculated polyp (5-20 mm). After polyp removal was considered complete macroscopically, biopsies were obtained from the resection margin. The main outcome was the percentage of incompletely resected neoplastic polyps (incomplete resection rate [IRR]) determined by the presence of neoplastic tissue in post-polypectomy biopsies. …

Adenoma Characteristics At First Colonoscopy As Predictors Of Adenoma Recurrence And Characteristics At Follow-Up, Rosalind U. Van Stolk, Gerald J. Beck, John A. Baron, Robert Haile, Robert Summers

Dartmouth Scholarship

All patients with colorectal adenomas may not require identical follow-up. We aimed to determine if adenoma characteristics at initial colonoscopy could predict adenoma recurrence or characteristics at follow-up. The number of adenomas and the size, type, and degree of atypia in 479 patients in a polyp prevention trial were evaluated as predictors of the same characteristics at follow-up using odds ratios (ORs) with 95% confidence intervals (CIs). Multiple logistic regression analysis was performed to determine if several baseline characteristics were simultaneously associated with outcome.
