• Two patients with gastrointestinal (GI) tract bleeding underwent preoperative selective visceral arteriography that demonstrated small-bowel tumors compatible with leiomyoma. A review of the material indicates that 42% of patients with small-bowel leiomyomas also have GI tract bleeding. Arteriography is valuable in obtaining a preoperative diagnosis.
