An apparatus for manipulating the rectosigmoid during surgery, to move the rectosigmoid to a pre-determined position, which includes a cannula portin, having a rounded and flexible tip, an inflatable balloon surrounding at least a portion of the cannula; the balloon inflatable with water, gas, or dye; a cone at a first end of the cannula for sealing around the opening of the anus; a stylet insertable in the cannula opening to provide partial rigidity to the cannula; and a syringe lock for introducing the fluid into the balloon, so as to provide a soft yet somewhat rigid device for allowing gentle manipulation of the recto-sigmoid during surgical procedures. The method performed with the apparatus of the present invention would include the steps of providing a cannula of a certain length, around 20 cm-30 cm; providing an inflatable balloon around at least a portion of the cannula; providing a cone end to at least a first end of the cannula; inserting a hook stylet into the cannula opening to provide some rigidity to the cannula; inserting the second end of the cannula upon which the balloon surrounds into the rectum to a distance of around 10 to 20 cm balloon length; sealing the cone end to the outer surface of the anal opening; inserting a fluid into the balloon to inflate the balloon to around 3 cm-5 cm; moving the outer end of the stylet extending from the cannula in a first direction so that the second end of the cannula is moved in the opposite direction and manipulates the rectosigmoid in that direction.
