The ostomy appliance also includes at least one window formed in the pouch facing side, the at least one window aligned with a distal portion of the fluidic channel such that a portion of the fluidic channel is visible through the window. In another embodiment, an ostomy appliance includes a skin barrier material and an ultrasonic detection device for monitoring the skin barrier material.
