title: [A Case of Adult Invagination Caused by Rectal Cancer].
abstract: An 87-year-old man visited our hospital with a chief complaint of melena. Invagination caused by rectal cancer or sigmoid colon cancer was suspected as a result of physical and radiological examinations. Since there were no subjective symptoms, laparoscopic surgery was planned electively. As an operative finding, a tumor was found in the rectosigmoid colon and caused invagination. The invagination was released during an operation, and high anterior resection with D3 dissection was performed laparoscopically. The operation time was 108 minutes and the amount of blood loss was 22 mL. Although anastomotic leakage occurred as a postoperative complication, recovery was achieved conservatively by percutaneous drainage. In many cases, invagination of adults is caused by a solid tumor such as bowel carcinoma, which commonly occurs at the cecum or sigmoid colon. Although invagination of the rectosigmoid colon fixed to the retroperitoneum is relatively rare, the fragility of the supporting tissues in the pelvis accompanied by aging is considered to be a cause. In cases of a large tumor occupying the lumen of the intestine, appropriate preoperative diagnosis is needed and the method of operation should be chosen carefully.
