BACKGROUND: Water delivery tube reflux during gastrointestinal endoscopy examination is widespread and it is the leading cause of water injection bottle pollution.

AIM: To evaluate the application effect of a new anti-reflux water injection tube device in preventing the contamination of endoscopy water injection bottles.

METHODS: A total of 520 cases received gastrointestinal endoscopy examination were included. Patients were randomly divided into the experimental and control group. The experimental group used the anti-reflux injection tube device to assist with water injection, and the control group used the ordinary delivery tube. After every five cases of gastrointestinal endoscopy, water from the injection bottles was collected. Visual inspection, crystalline violet staining, microbial culture, and microbial species analysis were performed to analyze the contamination state of the water samples.

RESULTS: The contamination rate in the experimental group was 5.66%, significantly lower than 76.47% in the control group. Crystalline violet staining confirmed that microorganisms existed in contaminated water samples. Microbiological culture results showed that the experimental group's undetectable rate of bacteria and fungi was 100%, significantly higher than that of the control group (19.61% for bacteria and 25.49% for fungi). The mean values of the total bacterial and fungal colonies of the control samples were 9.80 × 106 cfu/ml and 9.18 × 106 cfu/ml, respectively. The microbial species in the contaminated samples of the control group were Pseudomonas aeruginosa, Escherichia coli, and Proteus mirabilis.

CONCLUSION: The anti-reflux water injection tube device can effectively prevent the contamination of the endoscopy water injection bottles caused by the reflux of the ordinary water supply tube.
