Article Abstract
Background: Colonoscopy is considered the most effective method for diagnosing colorectal diseases, but its application is sometimes limited due to invasiveness, patient intolerance, and the need for sedation.
Objective: The aim of this study was to improve the problem of loop formation and shorten the cecal intubation time of colonoscopy by using a magnetic control system (MCS).
Methods: Two experienced gastroenterologists, three trainees, and a novice repeated colonoscopy without or with MCS on three colonoscopy training model simulator cases. These cases were divided into introductory (case 2) and challenging levels (cases 4 and 5). The cecal intubation times were recorded.
Results: For all cases, the average cecal intubation times for the experienced gastroenterologists with MCS were significantly shorter than without MCS (case 2: 52.45 vs. 27.65 s, p < 0.001; case 4: 166.7 vs. 120.55 s, p < 0.01; case 5: 130.35 vs. 100.2 s, p < 0.05). Those of the trainees also revealed significantly shorter times with MCS (case 2: 67.27 vs. 51 s, p < 0.01; case 4: 253.27 vs. 170.97 s, p < 0.001; case 5: 144.1 vs. 85.57 s, p < 0.001).
Conclusion: Conducting colonoscopy with MCS is safe and smooth, and shortens the cecal intubation time by navigating the forepart of the colonoscope. In addition, all diagnostic and therapeutic benefits of conventional colonoscopy are retained.

Purpose Of Review: This review summarizes current landscape of colonoscopy quality metrics, with an emphasis on priority intraprocedural indicators. We aim to clarify the rationale, evidence, and practical implementation of both traditional and recently introduced metrics-highlighting which measures are most relevant for improving patient outcomes in 2025.
Recent Findings: The 2024 ACG/ASGE guidelines reaffirmed the core quality indicators of adenoma detection rate (ADR), cecal intubation rate (CIR), bowel preparation adequacy, and guideline-based surveillance interval assignment.
