A guide and method for tilting a colonoscope in the rectum during a colonoscopy to attain a favorable direction for advancement of the scope through the colon. The guide comprises an at least partially rigid, elongated body member that, preferably, is attached to a handle at its proximal end. The body member can have a flat or curved cross-section. One or more ring members can be provided along the length of the body member to receive the scope and maintain the guide in close abutting relation therewith. The ring members can be slotted to allow side-loading of the guide onto the scope. Alternatively, a rigid or graduated rigid tubular member can be part of the guide member. An injection port allows injection of a lubricant. By tilting the colonoscope at various difficult stages of a colonoscopy, sigmoid looping is minimized to facilitate advancing the scope through the colon.
