Radiology in cutaneous sinuses and fistulae.

In patients with cutaneous openings, sinography and fistulography are usually performed. Fistulae in the head/neck region and perineum are seldom life-threatening while enterocutaneous fistulae involving the small bowel can be a serious threat due to loss of fluid. Radiology contributes to the preoperative examination of these patients. Fistulography outlines communications to the gastrointestinal tract, pleura, joints and other underlying crucial structures. Involved bowel segments are further demonstrated with barium examination.
