Abstract:
Objective To explore the applicative value of blue Laser imaging combined with magnifying endoscope(BLI+ME)system for the lesion of esophagogastric junction(EGJ).Methods Retrospective study endoscopic and pathological reported during February 2022 to February 2024.6 803 patients who met the inclusion and exclusion criteria were enrolled.They were divided into BLI+ME group(2 931 cases)and white light imaging group(WLI group,3 872 cases)according to the different gastroscopy types used in the examination.Finally,the EGJ biopsy rate,positive biopsy rate,detection rate of various lesions and early diagnosis rate between the two groups were compared.Results The biopsy rate of the BLI+ME group was 27.60%,the positive biopsy rate was 68.73%,and the detection rate of all the lesions was 20.74%,the detection rate of non-cancerous lesions was 20.30%,the detection rate of early cancer was 0.10%,the detection rate of non-cancerous lesions above the dentate line was 5.53%,the detection rate of non-cancerous lesions below the dentate line was 14.77%,the detection rate of cancerous lesions below the dentate line was 0.27%,significantly higher than those of the WLI group,which the biopsy rate was 17.74%,the positive biopsy rate was 60.26%,and the detection rate of all the lesions was 11.90%,the detection rate of non-cancerous lesions was 11.67%,the detection rate of early cancer was 0.00%,the detection rate of non-cancerous lesions above the dentate line was 3.49%,the detection rate of non-cancerous lesions below the dentate line was 8.19%,the detection rate of cancerous lesions below the dentate line was 0.05%,the differences were statistically significant(P＜0.05).Conclusion The BLI+ME system can enhance the biopsy rate,positive biopsy rate,the detection rate of all the lesions,early cancer detection rate,non-cancerous lesions detection rate above and below the dentate line,and cancerous lesions detection rate below the dentate line at the EGJ.It is helpful to improve the early diagnosis rate and early treatment rate of EGJ.It is worthy of clinical application.
