Not always. Flexible endoscopes are difficult to clean and disinfect because of their long and narrow lumens and delicate materials. A study by Pajkos et al.1 suggests that current cleaning procedures are inadequate as soil or biofilm was found present in all 12 endoscopes investigated. Fragments of soil may be transferred to patients and immuno-compromised patients are at risk of contracting infections from pathogenic organisms as well as from opportunistic organisms such as fungi and pseudomonas1.
With the increasing risk of resistant bacterial strains, the aScope 3 and aScope 3 Slim offer a unique opportunity to avoid the risk of cross contamination as well as the hassle and costs of the reprocessing procedures thus releasing valuable resources for other procedures.
Figure 1a and 1b show a scanning electron micrographs of a suction channel that show surface defects.
Figure 2a and 2b show a scanning electron micrographs of two different air/water channelswith biofilms.
On figure 1a, the biological soil is associated with the defects and is also attached to undamaged areas.
On figure 1b, a magnification of one of the defect areas that shows soil and various types of micro-organisms.
On figure 2a, a low-power view showing a confluent layer of soil and biofilm.
On figure 2b, a multilayered biofilm consisting of healthy-looking cells surrounded and overlayed with amorphous-looking exopolysaccharides.
