Method for draining and decompressing a colon in which a drainage tube is inserted through the anus into the colon to extend through the entire colon. The drainage tube is fixed in position and suction is applied therethrough to cause fecal matter to pass therein through apertures and be withdrawn from the colon. The drainage tube is inserted by inserting a guidewire into the colon through the anus, manipulating and pushing the guidewire to the cecum, passing a filament through the colon wall to engage the guidewire, pulling the guidewire out of the colon and anus to draw the filament through the colon and out of the anus, attaching the drainage tube to the filament and drawing the filament with attached drainage tube through the anus into the colon. The invention also relates to constructions of the guidewire, the drainage tube and methods for inserting drainage tubes using guidewires.
