Abstract
A 47-year-old man had a total colonoscopy based on a positive fecal occult blood test. It showed a type 2 tumor with 1/2 circle in the anterior wall of the superior rectum. The biopsy offered a diagnosis of poorly differentiated adenocarcinoma. Preoperative diagnosis was SE, N1, H0, M0 cStage 3a. Also the preoperative examination showed the left pelvic kidney was also affected. We performed a laparoscopic low anterior resection in anticipation of the magnifying effect of laparoscopic surgery. We found multiple small liver metastasis during the operation. The pathological diagnosis was por, Ra, type 2, 40∗ 40mm, pSS, pN2, sH3, sP0, ly3, v1, pPM (-), pDM (-), Stage 4. In this case, we faced rectal cancer with the left pelvic kidney, and expected that the operative view would be very narrow. But because laparoscopic surgery has a magnifying effect, we could operate easily although the narrow pelvic space created by the left pelvic kidney. In this case of rectal cancer with the left pelvic kidney, we considered that laparoscopic surgery was an effective method.
