Computer-aided quality control in colonoscopy: clinical applications and limitations: Elizabeth Lee Yoong Chen, James Weiquan Li; Received August 30, 2025 Accepted October 23, 2025 Published online December 17, 2025; DOI: https://doi.org/10.5946/ce.2025.309 [Epub ahead of print]

Computer-aided quality control (CAQ) systems are redefining colonoscopy by enabling the objective evaluation of procedural metrics and providing real-time feedback. This review explores the clinical utility, implementation barriers, and future prospects of CAQ, with an emphasis on its role in standardizing quality assessment and enhancing patient outcomes. A systematic search of PubMed (inception to January 2025) identified 66 relevant publications, including eight systematic reviews or meta-analyses, seven randomized controlled trials, and five cohort studies, in addition to validation and observational reports. CAQ systems improve traditional quality indicators such as withdrawal time, bowel preparation scores, and cecal intubation rates (CIRs). Emerging metrics—including effective withdrawal time, fold examination quality, and withdrawal speed—offer novel, quantifiable insights. Artificial intelligence-assisted colonoscopy consistently increases adenoma detection rates (from 38.5% to 47.9%) and extends withdrawal time (from 5.68 to 7.03 minutes). Automated systems achieve high accuracy in bowel preparation scoring (93.3%), cecal intubation recognition (95.5%), and surveillance interval assignment (92.0%), thereby addressing persistent gaps in documentation and follow-up care. CAQ systems hold transformative promise for improving colonoscopy quality. Addressing implementation challenges—including false positives, clinician adoption, cost, and regulatory issues—is essential. Future research should emphasize comparative effectiveness, standardized metrics, and large-scale clinical integration to help reduce the burden of colorectal cancer.

Special Review: Korean Society of Gastrointestinal Endoscopy “Accreditation of Qualified Endoscopy Unit” Guideline: Update 2019

Updates on the Disinfection and Infection Control Process of the Accredited Endoscopy Unit: Jeong Eun Shin, Yunho Jung, Jeong Hoon Lee, Byoung Kwan Son, Jae-Young Jang, Hyung-Keun Kim, Byung Ik Jang, The Quality Management Committee and the Disinfection Management Committee of Korean Society of Gastrointestinal Endoscopy; Clin Endosc 2019;52(5):443-450. Published online September 30, 2019; DOI: https://doi.org/10.5946/ce.2019.173

Abstract PDF PubReader ePub

A thorough disinfection and infection control process associated with gastrointestinal endoscopy is highly important for the health and safety of the examinee and the medical staff involved in the procedure. Endoscopic reprocessing and disinfection are two of the most important steps in quality control of endoscopy. In 2019, the Korean Society of Gastrointestinal Endoscopy updated the Accreditation of Qualified Endoscopy Unit assessment items for these quality indicators. Assessment of disinfection and infection control comprises 28 mandatory items in the categories of disinfection education, pre-cleaning, cleaning, disinfection, rinsing, drying, reprocessing, storage, endoscopic accessories, water bottle and connectors, space/facilities, personal protective equipment, disinfection ledger, and regulations regarding infection control and disinfection.
The updated Accreditation of Qualified Endoscopy Unit assessment items are useful for improving the quality of endoscopy by ensuring thorough inspection of endoscopic disinfection and infection control.

Focused Review Series: Globalization and Universalization of ESD

Principles of Quality Controlled Endoscopic Submucosal Dissection with Appropriate Dissection Level and High Quality Resected Specimen: Takashi Toyonaga, Eisei Nishino, Mariko Man-i, James E. East, Takeshi Azuma; Clin Endosc 2012;45(4):362-374. Published online November 30, 2012; DOI: https://doi.org/10.5946/ce.2012.45.4.362

Abstract PDF PubReader ePub

Endoscopic submucosal dissection (ESD) has enabled en bloc resection of early stage gastrointestinal tumors with negligible risk of lymph node metastasis, regardless of tumor size, location, and shape. However, ESD is a relatively difficult technique compared with conventional endoscopic mucosal resection, requiring a longer procedure time and potentially causing more complications. For safe and reproducible procedure of ESD, the appropriate dissection of the ramified vascular network in the level of middle submucosal layer is required to reach the avascular stratum just above the muscle layer. The horizontal approach to maintain the appropriate depth for dissection beneath the vascular network enables treatment of difficult cases with large vessels and severe fibrosis. The most important aspect of ESD is the precise evaluation of curability. This approach can also secure the quality of the resected specimen with enough depth of the submucosal layer.

Usefulness of Real-time Measurement of Colonoscopy Withdrawal Time during Fellow Training: Chung Hyun Tae, M.D., Sung-Ae Jung, M.D., Seung-Jung Jun, M.D., Sun-Hee Roh, M.D., Ju Young Choi, M.D., Min Jung Kang, M.D., Ji Min Jung, M.D., Seong-Eun Kim, M.D., Ki-Nam Shim, M.D., Hey-Kyung Jung, M.D., Tae Hun Kim, M.D., Kwon Yoo, M.D. and Il-Hwan M; Korean J Gastrointest Endosc 2011;42(6):356-360. Published online April 16, 2011

Abstract PDF: Background/Aims: Attempts to increase colonoscopy withdrawal time have been the topic of several recent publications. We assessed whether the real-time measurement of withdrawal time affected the withdrawal time and polyp detection rate. Methods: Real-time colonoscopy withdrawal time was measured in 197 subjects in a study group and 184 subjects comprised a control group without real-time measurements. Colonoscopies were performed by four endoscopy specialists and three fellows during their first year of training. Withdrawal time, clinical features, bowel preparation, and polyp detection rates were comparatively analyzed. Results: No significant differences in age, gender, bowel preparation, or polyp history were found in the two groups. Withdrawal time was significantly higher in the study group than that in the control group when a fellow performed the withdrawal. However, polyp detection rate did not significantly increase in the study group, regardless of physician. Conclusions: Real-time measurement of colonoscopy withdrawal time did not increase polyp detection rate, but the withdrawal time was significantly higher when a fellow performed the withdrawal phase than when a specialist performed withdrawal. Therefore, the real-time measurement of colonoscopy withdrawal time seems to be a useful tool for fellow training.

Quality Control for Upper Gastrointestinal Endoscopy: Jae Myung Park, M.D.; Korean J Gastrointest Endosc 2010;40(6):343-346. Published online June 30, 2010

Abstract PDF: Upper gastrointestinal endoscopy is the most common procedure in the field of gastroenterology. Controlling the quality of endoscopy is quite important because gastric cancer is the most prevalent cancer in Korea. For each endoscopic procedure, the indicators of quality control can be considered for 3 time periods: the preprocedure, intraprocedure and postprocedure periods. The common issues during preprocedure include the proper indications, the patient's consent for the procedure, the patient's clinical status and the risk assessment, and the steps to reduce the risk. The common issues during intraprocedure include all the technical aspects of the procedure, including completion of the examination and any of the therapeutic maneuvers. The postprocedure activities include providing instructions to the patient, documentation of the procedure, recognition and documentation of complications, follow-up of the pathologic conditions and assessing the patient's satisfaction. Regular monitoring the quality of endoscopy can raise the level of performing endoscopic procedures.(Korean J Gastrointest Endosc 2010;40:343-346)
