title: [Laparoscopic Surgery for Adult Intussusception Due to Rectal Cancer--A Case Report].
abstract: An 87-year-old woman with the chief complaint of bloody stool was referred to our hospital from an institution for the aged. The abdomen was soft and flat, and a tumor was not palpable on digital rectal examination. Tumor markers were within normal ranges. Abdominal enhanced CT scan showed a multiple concentric ring sign at the rectum. Colonoscopic and barium examination led to a diagnosis of rectal intussusception due to rectal cancer. We first tried to reposition it preoperatively, but it was impossible. She fortunately had no symptoms of ileus; therefore, we chose to perform laparoscopic surgery. We achieved the reposition intraoperatively and performed Hartmann's operation with D2 lymph node dissection because she was a very elderly patient with high-risk comorbidities. The pathological diagnosis was as follows: RS, 40×40 mm, type 2, tub2, pT3 (SS), pN0, ly0, v0, pStageⅡ, R0, Cur A. Adult intussusception due to rectal cancer is extremely rare. We report that in this case that laparoscopic surgery was possible, along with a review of the relevant literature.
