Egestion is the discharge or expulsion of undigested material (food) from a cell in case of unicellular organisms, and from the digestive tract via the anus in case of multicellular organisms. 

It should not be confused with excretion, which is getting rid of waste formed from the chemical reaction of the body, such as in urine, sweat.

excretion is the removal of the nitrogeneous waste from the body through the excretory system.

whereas egestion is the process of removal of the undigested food from the body.
