The present invention relates to an endoscope sheath, more specifically to an endoscope sheath that provides rear view of a hollow body organ when used in conjunction with a corresponding endoscope at the same time when the corresponding endoscope provides forward view of the hollow organ. The endoscope sheath is sized to slip over a corresponding endoscope. It comprises of a rear view module containing a rear image lens and a rear illumination bulb. The rear view module is designed and is attached to the endoscope sheath in a way that when deployed, the rear image lens and the rear illumination bulb face backward with respect to the forward axis of the corresponding endoscope. In this position, the rear image lens of the endoscope sheath provides a rear view while the main image lens of the endoscope provides forward view. The ability to obtain forward and rear view at the same time enables the operator to perform a complete examination of a hollow organ in a single insertion.
