A method and apparatus for removing loops formed during endoscopic procedures including colonoscopy and small bowel enteroscopy. The device inserted through the biopsy channel of an endoscope reversibly engages the distal portion of the biopsy channel of the endoscope. When pressure is applied to the device handle external to the endoscope, the force is transmitted to the distal end of the endoscope advances and straightens out the loop. When the device is torqued, the distal end of the engaged endoscope torques which can remove a twist in the endoscope as well. Neither procedure requires removal of a portion of the scope or loss of position which occurs with conventional methods.
