title: Adult colonic intussusception: a case report.
abstract: 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.
