A comparison of the efficacy of lumen-cleaning devices for flexible gastrointestinal endoscopes

The cleaning efficacy of a new lumen cleaning device for endoscopes, a 'Pull Thru', was compared to cleaning devices that use brushes. Efficacy was tested by applying a simulated blood soil to lumens of two different diameters (to match those of biopsy and suction lumens, which require manual cleaning) and comparing the weight difference before and after cleaning. The Pull Thru device was found to offer a consistently significant improvement in soil removal and was equally effective across both lumen sizes and for both new and used lumens.
