摘要：
An apparatus includes a body configured to be at least partially inserted into a rectum of a patient. The body defines a first passageway and a second passageway between a proximal end portion and a distal end portion. The first passageway is configured to receive a medical tool and the second passageway is configured to communicate an insufflation medium. An insufflation port is coupled to the second passageway and is configured to communicate the insufflation medium to the second passageway. A retention portion is coupled to the body and is configured to have a dimension transverse to an axis defined by the body sufficient to retain at least a portion of the body in the rectum. The retention portion is configured to be located beyond an anus of the patient.
