Brief Summary

The investigators plan to adopt a thorough flushing strategy when withdrawing the endoscope, and have zero tolerance for the liquid and foam in the intestinal lumen. Observe and compare the impact of this strategy with traditional limited degree suction methods on the results of colonoscopy. The research group and the control group respectively adopted a thorough flushing strategy and a limited flushing strategy, and compared the total time of colonoscopy examination, the time of withdrawal, the detection rate of polyps, the detection rate of small polyps, and the amount of flushing fluid between the two groups. Analyze the value of thorough flushing strategy for the efficiency and quality of colonoscopy examination.

Procedure: thorough flushing

Interventions

thorough flushing PROCEDURE

The thorough flushing strategy refers to the thorough flushing of all liquid and foam accumulation areas during the inspection. Make all liquid accumulation parts in the intestinal cavity free of aspiratable liquid retention

thorough

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

160 patients were selected for colonoscopy examination and randomly assigned to the study group and control group. The two groups used a thorough flushing strategy and a limited flushing strategy to complete colonoscopy examination. The research group adopted a thorough flushing strategy, while the control group adopted a limited flushing strategy. The thorough flushing strategy refers to the thorough flushing of all liquid and foam accumulation areas during the inspection. Make all the liquid accumulation parts in the intestinal cavity free of aspiratable liquid retention. The limited flushing strategy refers to not pursuing full liquid suction, but flushing until it is clear enough for observation. The limited flushing strategy is currently the conventional flushing method for colonoscopy.
