Correlation of disinfection quality of digestive endoscopes with residual tissue glue in forceps channels

Objective To explore the effect of residual tissue glue in forceps channels on the disinfection quality of digestive endoscopes.

Methods A total of 103 forceps channels of digestive endoscopes in the Digestive Endoscopy Center of the hospital from March 2022 to June 2023 were randomly selected, and the residual situation of tissue glue in the forceps channels of the endoscopes was observed after cleaning and disinfection. The endoscopes were divided into residual group and non-residual group based on the residual situation of tissue glue in the forceps channels, the disinfection quality and microbial conditions of digestive endoscopes in both groups were detected, and the factors affecting the disinfection quality of digestive endoscopes were analyzed.

Results Among the 103 forceps channels, 70 channels (67.96%) had residual tissue glue; the disinfection qualification rate and bacteriological qualification rate of the non-residual group were significantly higher than those of the residual group (P<0.05). There were four personnel carrying out disinfection, and the proportion of qualified disinfection water quality was higher than that of poor group (P<0.05).

Conclusion The higher the residual rate of tissue glue in forceps channels and the bacterial detection rate are, and the lower the disinfection quality of digestive endoscopes is. The quality of disinfection water and the number of disinfection personnel can affect the disinfection quality of digestive endoscopes.
