Abstract:
Objective:To analyze differences in detection rates for gastric precancerous lesions and neoplasms before versus after implementing a computer-aided detection (CADe) system in real-world clinical practice.Methods:Clinical data of patients who underwent gastroscopic examinations in two examination rooms (Room 1 and 2) in the Digestive Endoscopy Center of Renmin Hospital of Wuhan University were retrospectively collected during two periods: from January to June 2018 and from January to June 2021. Patients were stratified into four groups: CADe group (Room 2, 2021, using CADe), Pre-CADe group (Room 2, 2018, without CADe), 18-Con group (Room 1, 2018, without CADe), and 21-Con group (Room 1, 2021, without CADe). The differences in the detection rates of intestinal metaplasia and neoplasms between different groups were compared.Results:The detection rate of intestinal metaplasia in the CADe group was significantly higher than that in the Pre-CADe group [5.76% (198/3 437) VS 3.23% (100/3 092), χ2=23.856, P<0.001]. It was also significantly higher than that in the 21-Con group [5.76% (198/3 437) VS 2.73% (131/4 796), χ2=47.895, P<0.001]. The detection rate of neoplasms in the CADe group was significantly higher than that in the Pre-CADe group [3.23% (111/3 437) VS 1.58% (49/3 092), χ2=18.421, P<0.001] and the 21-Con group [3.23% (111/3 437) VS 1.79% (86/4 796), χ2=17.687, P<0.001]. Conclusion:The CADe system can significantly improve the detection rates of gastric intestinal metaplasia and neoplasms in clinical settings, potentially facilitating early diagnosis and treatment.
