1. A method for cleaning a colon, comprising:
inserting a fluid supply pipe into an anal canal opening at least 150 cm into the colon while a proximal end of the fluid supply pipe remains outside the colon;
supplying fluid to the proximal end of the fluid supply pipe as a mix of liquid segments cyclically alternating with gas segments to be supplied to the colon, wherein said mix of liquid segments cyclically alternating with gas segments includes at least two liquid segments and at least two gas segments located in said fluid supply pipe simultaneously;
wherein each of the gas segments is compressed in volume between a pair of liquid segments while traveling along the fluid supply pipe;
wherein said supplying including supplying the mix of alternating liquid and gas segments in sequences in the fluid supply pipe; and
producing pulsed shockwaves of gas segments exiting a distal end of the fluid supply pipe.
