Internal malignant fistulae of the gastrointestinal tract involving two or more loops of different segments of the bowel are rare. The colon is frequently one of the participating loops. Observations on four such cases indicate that the fistulous tract connecting the two bowel loops is usually linear, somewhat wide, and does not produce significant approximation of the bowel loops involved. These radiographic features help to differentiate such fistulae from the benign type.
涉及肠道不同节段两个或更多肠袢的胃肠道内恶性瘘管很少见。结肠常常是受累肠袢之一。对4例此类病例的观察表明，连接两个肠袢的瘘管通常呈线状，有点宽，且不会使受累肠袢明显靠近。这些影像学特征有助于将此类瘘管与良性瘘管区分开来。
