Intussusception accounts for almost all cases of intestinal obstruction in children. In contrast, intussusception in adults is relatively rare. An 86-year-old Japanese female with rectal bleeding came to our hospital via ambulance. At first, colonoscopy findings revealed the sigmoid colon cancer. Ultrasonography showed a hypoechoic mass with a multiple concentric ring sign. Computed tomography showed a round fluid-filled cystic structure. Colon contrast studies demonstrated stenosis in the rectosigmoid colon. A laparotomy was performed. The sigmoid colon was intussuscepted to the rectosigmoid colon. We employed both rectosigmoid and sigmoid colon resection. The resected specimen showed that the disease was advanced sigmoid colon cancer with ulcer formation due to an ischemic change. Tumor was 4.5 cm x 2.0 cm in size. The disease was histopathologically diagnosed as advanced sigmoid colon cancer, well-differentiated adenocarcinoma. We report here a case of adult intussusception due to the sigmoid colon cancer.
肠套叠几乎是儿童肠梗阻的所有病例原因。相比之下，成人肠套叠相对少见。一名86岁有直肠出血的日本女性经救护车送至我院。起初，结肠镜检查发现乙状结肠癌。超声检查显示一个低回声肿块伴有多个同心圆征。计算机断层扫描显示一个圆形的充满液体的囊性结构。结肠造影研究显示直肠乙状结肠狭窄。进行了剖腹手术。乙状结肠套入直肠乙状结肠。我们实施了直肠乙状结肠和乙状结肠切除术。切除标本显示该疾病为晚期乙状结肠癌，因缺血性改变形成溃疡。肿瘤大小为4.5厘米×2.0厘米。该疾病经组织病理学诊断为晚期乙状结肠癌，高分化腺癌。我们在此报告一例因乙状结肠癌导致的成人肠套叠病例。
