研究设计:

随机平行对照 

Study design:

研究目的:

评估链霉蛋白酶在无痛胃镜检查中对提高内镜视野及微小病灶检出率的效果,明确链霉蛋白酶联合二甲硅油的用药方案是否能显著提升内镜视野清晰度,有效减少胃内黏液附着,进而提高胃内微小病灶、癌前病变及早期胃癌的检出率。  

Objectives of Study:

To evaluate the efficacy of streptodornase in improving endoscopic visualization and the detection rate of tiny lesions during painless gastroscopy, and to clarify whether the medication regimen of streptodornase combined with dimethicone can significantly enhance the clarity of endoscopic vision, effectively reduce gastric mucus adhesion, and thereby improve the detection rate of tiny gastric lesions, precancerous lesions, and early gastric cancer.
