Introduction: Stool DNA testing based on methylated syndecan-2 (mSDC2) is a potential novel non-invasive screening test for colorectal cancer (CRC). This study aimed to assess its positive predictive value (PPV) in real-world practice.

Methods: This study retrospectively recruited consecutive patients with positive stool DNA-based SDC2 methylation tests from 18 hospitals between November 2016 and July 2021.

Article Synopsis
  • A study was conducted in China to create a validated model for assessing the risk of colorectal neoplasia (CN) using a fecal immunochemical test (FIT) due to limited colonoscopy resources.
  • The National Colorectal Polyp Care (NCPC) score was developed from eight factors and categorized individuals into low, intermediate, and high-risk levels for CN, guiding recommendations for colonoscopy.
  • The model successfully identified a significant proportion of CN and early-onset colorectal cancers, demonstrating its effectiveness in a diverse population, including young individuals and those with nonspecific gastrointestinal symptoms.

Introduction: Although the 9-minute mean withdrawal time (m-WT) is often reported to be associated with the optimal adenoma detection rate (ADR), no randomized trials of screening colonoscopy have confirmed the impact of a 9-minute m-WT on adenoma miss rate (AMR) and ADR.

Methods: A multicenter tandem trial was conducted in 11 centers. Seven hundred thirty-three asymptomatic participants were randomized to receive segmental tandem screening colonoscopy with a 9-minute withdrawal, followed by a 6-minute withdrawal (9-minute-first group, 9MF, n = 366) or vice versa (6-minute-first group, 6MF, n = 367).

Impact of 9-Minute Withdrawal Time on the Adenoma Detection Rate: A Multicenter Randomized Controlled Trial.

Background & Aims: Although current quality indicators of colonoscopy recommend 6 minutes as the minimum standard for withdrawal time (WT), the impact of a WT longer than 6 minutes on neoplasia detection is unclear.

Methods: A multicenter randomized controlled trial involving 1027 patients was conducted from January 2018 to July 2019. Participants were randomly divided into a 9-minute (n = 514) and 6-minute (n = 513) WT group, and a timer was used to adjust the withdrawal speed.

Magnitude, Risk Factors, and Factors Associated With Adenoma Miss Rate of Tandem Colonoscopy: A Systematic Review and Meta-analysis.

Department of Gastroenterology, Changhai Hospital, Second Military Medical University and Naval Medical University, Shanghai, China; Digestive Endoscopy Center, Changhai Hospital, Naval and Second Military Medical University, Shanghai, China; National Clinical Research Center for Digestive Diseases,

Background & Aims: We performed a systematic review and meta-analysis to comprehensively estimate adenoma miss rate (AMR) and advanced AMR (AAMR) and explore associated factors.

Methods: We searched the PubMed, Web of Science, and Ovid EMBASE databases for studies published through April 2018 on tandem colonoscopies, with AMR and AAMR as the primary outcomes. We performed meta-regression analyses to identify risk factors and factors associated with outcome.
