Intended Use

This software is a computer-assisted reading tool designed to aid endoscopists in detecting colonic mucosal lesions (such as polyps and adenomas) in real time during standard endoscopy examinations of patients undergoing screening and surveillance endoscopic mucosal evaluations. This software is used with standard White Light Imaging (WLI) and Linked Color Imaging (LCI) endoscopy imaging. This software is not intended to replace clinical decision making.

Device Story

EW10-EC02 is an AI-based computer-aided detection (CAD) system for colonoscopy. It processes real-time endoscopic video input (WLI and LCI modes) to identify suspected colonic polyps and adenomas. The system overlays visual markers on the endoscope monitor to alert the endoscopist to potential lesions. Used in clinical settings by endoscopists, the device acts as a concurrent reading aid; it does not replace clinical judgment. By highlighting potential lesions in real-time, the device aims to increase polyp detection rates, potentially leading to earlier diagnosis and treatment of neoplastic lesions. The system is integrated into the endoscopy workflow, providing visual feedback without significantly delaying the procedure.

Clinical Evidence

Multi-center, prospective, randomized controlled trial (n=1,031) compared computer-assisted colonoscopy (CAC) to conventional colonoscopy (CC). Primary endpoints: Adenoma per colonoscopy (APC) and Positive Predictive Value (PPV). APC was superior in the CAC group (p=0.018). PPV criteria were met. Secondary endpoints included ADR, PDR, and lesion detection rates. Standalone performance testing (149 WLI/144 LCI videos) showed high sensitivity (95.1% WLI, 95.5% LCI) and low false-positive rates per patient.

Technological Characteristics

AI-based software algorithm for real-time polyp detection. Compatible with Fujifilm 700 series colonoscopes, VP-7000 video processor, and BL-7000 LED light source. Supports WLI and LCI imaging modes. Operates as a concurrent-read CAD system with visual marker overlays. Software verification/validation performed per FDA guidance. No hardware modifications; image quality degradation testing confirmed no visually detectable differences.

Indications for Use

Indicated for patients aged 45+ undergoing screening or surveillance colonoscopy to aid endoscopists in real-time detection of colonic mucosal lesions (polyps/adenomas). Contraindicated for patients with history of colon resection, IBD, FAP, or severe end-stage cardiovascular/pulmonary/liver/renal disease.

There is an increasing interest in the application of artificial intelligence (AI) in health care to improve disease diagnosis, management, and the development of effective therapies. The remarkable development of AI from deep learning in recent years has increased the possibility of machines assisting assessments by human visual observation. The subject device represents application of AI technology to endoscopic images to assist in detecting the presence of potential lesions. This development greatly contributes to improving the quality of colonoscopy. In recent years, computer-aided diagnosis (CAD) systems employing AI technologies have been approved and marketed as radiological medical devices for use with computed tomography (CT), X-ray, magnetic resonance imaging (MRI), and mammogram diagnostic images. In endoscopy as well, many images for diagnosis are taken. Since increasing the polyp detection rate is also in demand, CAD systems for endoscopy are being actively developed. Against this background, the company has developed this software (EW10-EC02), a new AI-based CAD system, to support Health Care Provider (HCP) detection of large intestine polyps in colonoscopic images. EW10-EC02 detects suspected large intestine polyps in the endoscope video image in real-time. # g.

This testing considers repeated marking overlays of the same target (lesions and false positives) as a single statistical event. This allows for an estimate of the number of unique targets (or objects) identified by EW10-EC02 as a function of the time those targets persist in the field of view. In this standalone performance testing, WLI has about four times more evaluation images than LCI, so there is a difference in FP Objects/Patient, but the relationship between FP Objects/Patient and Sensitivity per lesion in both modes was almost equivalent. {10}------------------------------------------------ Image /page/10/Figure/1 description: The image contains two plots comparing sensitivity per lesion vs the number of false positives per case. The plot on the left is labeled WLI and the plot on the right is labeled LCI. Both plots show a similar trend, with sensitivity increasing rapidly as the number of false positives increases from 0 to 20, and then leveling off. The sensitivity reaches nearly 100% with a small number of false positives. Figure 1: Figure demonstrating how detection persistence in time correlates with sensitivity per lesion and the number of FPc per "Case" (FP Objects/Patient); (L)WLI mode, (R)LCI mode The frame-level performance is an assessment of the accuracy of the algorithm at sorting endoscopic images for quantification of false positives, false negatives, true positives, and true negatives.

The first graph is titled "ROC analysis in WLI mode (Overall view)" and has an AUC of 0.79 with a 95% confidence interval of 0.77-0.80. The second graph is titled "ROC analysis in LCI mode (Overall view)" and has an AUC of 0.87 with a 95% confidence interval of 0.86-0.88. Both graphs plot the True Positive Rate on the y-axis and the False Positive Rate on the x-axis. Figure 3: ROC analysis; (L)WLI mode, (R)LCI mode Image /page/11/Figure/3 description: The image contains two FROC analysis graphs, one in WLI mode and the other in LCI mode, both displaying an overall view. The x-axis of both graphs represents the number of FPc (False Positives per case), while the y-axis represents the sensitivity per lesion. The WLI mode graph shows the number of FPc per case ranging up to 200, while the LCI mode graph shows the number of FPc per case ranging up to 60. Both graphs show a similar trend, with sensitivity per lesion increasing rapidly at lower FPc values and then plateauing as FPc increases. Figure 4: FROC analysis; (L)WLI mode, (R)LCI mode # Standalone Performance Conclusions EW10-EC02 achieved all criteria in both modes and showed good results for each subgroup on both items of sensitivity and false positives. In addition, sensitivity analysis and FPc analysis further support robust results for EW10-EC02. ROC-AUC and FROC analysis also supports that performance of the EW10-EC02 algorithm. # Special Control Testing - √ Pixel-level comparison of degradation of image quality due to the device; No visually detectable differences between images were found with the introduction of the EW10-EC02. - √ Video delay due to marker annotation was 4.00 frames average (66.7 msec). - √ Real-time endoscopic video delay due to the device was 3.67 frames average (61.2 msec). # • Human Factors The data collected in the pivotal clinical study is sufficient to support usability as it demonstrates the ability to appropriately use the device in an actual clinical setting. {12}------------------------------------------------ # •Clinical Testing # Study Design This study was a multi-center, prospective, randomized controlled trial. Each subject had a colonoscopy, using FUJIFILM's High Definition (HD) endoscope, video processor and the EW10-EC02 endoscopy support program. The study was conducted at 12 centers in the United States. Subjects met all eligibility criteria were randomly allocated to 1 of 2 arms: - (1) CAC(Computer Assisted Colonoscopy) group: inspection with computer assisted colonoscopy. Or - (2) CC(Conventional Colonoscopy) group: inspection with conventional colonoscopy. As per standard of care, polyps were resected when found, and sent to histopathology. ### Study Population This prospective study enrolled a total of 1,166 subjects. Of these subjects enrolled. 135 subjects were excluded from the analysis due to exclusionary reasons. A total of 1,031 subjects were analyzed, 600 were average risk subjects undergoing average risk screening colonoscopy and 565 subjects scheduled for follow-up colonoscopy due to a previous history of polyps 3 years or greater. These subjects provided an informed consent and were aged 45 or older. Patients were not enrolled if they were pregnant, refused to give an informed consent or had a history of colon resection, Inflammatory Bowel Disease (IBD), Familial Adenomatous Polynosis (FAP). severe end-stage cardiovascular/pulmonary/liver/renal disease.

Conclusion {20}------------------------------------------------ The EW10-EC02 Endoscopy Support Program has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device, GI Genius (K211951). The differences in indications and technological characteristics between the subject and predicate devices do not raise new concerns regarding safety and effectiveness as demonstrated by the non-clinical and clinical performance evaluation results. Therefore, the EW10-EC02 Endoscopy Support Program can be considered substantially equivalent to the similar legally marketed device.
