Enteroenteric intussusception caused by metastatic tumors is a very rare condition. Because of its rarity and rather mild abdominal physical presentation, preoperative diagnosis is not easily made. Two cases of enteric intussusception due to metastatic intestinal tumors, with the main symptom of melena, are reported. Intussusception was caused by metastatic liposarcoma in one patient and metastatic melanoma in the other. Both patients had long histories of malignant disease, for 15 and 8 years, respectively. They had undergone repeated surgical treatment for metastatic lesions. The diagnosis of enteric intussusception was initially made by computed tomographic scans and small bowel series and was confirmed by laparotomy and pathologic findings. We suggest that tumor metastasis to the small intestine with intussusception should be considered in patients with recurrent tumors and tarry stools.
转移性肿瘤引起的肠-肠套叠是一种非常罕见的病症。由于其罕见性以及腹部体征相对较轻，术前诊断不易做出。本文报告了两例因转移性肠道肿瘤导致的肠套叠病例，主要症状为黑便。其中一例患者的套叠由转移性脂肪肉瘤引起，另一例由转移性黑色素瘤引起。两名患者均有较长时间的恶性疾病史，分别为15年和8年。他们都因转移性病变接受过多次手术治疗。肠套叠最初通过计算机断层扫描和小肠造影做出诊断，并经剖腹手术和病理检查结果证实。我们建议，对于复发性肿瘤和柏油样便的患者，应考虑肿瘤转移至小肠并导致肠套叠的情况。
