Current status of digestive endoscopy diagnosis and treatment in Shanghai / 中华消化内镜杂志

To investigate the current status of digestive endoscopy diagnosis and treatment in Shanghai, and to provide decision-making support for the revision of the diagnostic and treatment standards and quality control criteria of digestive endoscopy in Shanghai. A total of 145 hospitals providing digestive endoscopy service were investigated through an online survey. The main survey contents were the situation of digestive endoscopists, the development of diagnosis and treatment technology, and the quality and safety situation. There were 1 212 digestive endoscopists in Shanghai, accounting for 1.59% of China which ranked first in all registered practioners in 2019. The annual diagnostic and treatment procedures of digestive endoscopy was 1 902.6 thousand, and endoscopists' working pressure was relatively high. In terms of quality control indicator of a single disease, detection rates of early gastrointestinal cancers and adenomas remained at a high level. The number of digestive endoscopists, endoscopic procedures and quality control indicators of a single disease in Shanghai was in a leading position in China in 2019.

The feasibility of slightly acidic electrolyzed oxidizing water for the disinfection of gastrointestinal endoscopes / 中华消化内镜杂志

Objective To evaluate the feasibility of slightly acidic electrolyzed oxidizing water for the disinfection of gastrointestinal endoscopes.Methods Electrolyzed oxidizion water generator was utilized to produce the water,which was applied for the disinfection of gastrointestinal endoscopes.The disinfectant efficiency and effect were evaluated.Results A total of 215 samples were taken for bacterial culture after the disinfection.The mean sterilization efficiency of slightly acidic electrolyzed oxidized water and 2％ glutaraldehyde by machine were 99.92％ and 99.85％,respectively,while the mean sterilization efficiency were 99.85％ and 99.84％ by manual disinfection.There were no statistical significance between the two groups.The effective rates of both groups were 100％.No deformation or aging was observed in the endoscopes.The disinfectant caused no damage to the cleansing and disinfection.Conclusion It is feasible to apply slightly acidic electrolyzed oxidizing water to the disinfection of endoscopes.
