A Case of Synchronous Colorectal Cancer Successfully Treated by Laparoscopic Surgery with Two Segmental Anastomoses

: A 63-year-old man was admitted for the evaluation of Hb 4.8 g/dL anemia. He underwent colon fiberscopy and was subsequently diagnosed with synchronous cancers of the ascending colon and rectum. He underwent laparoscopic ileocecal resection and low anterior resection with 2 segmental anastomoses. The histopathological diagnosis of A/C and rectal cancer was Stage Ⅱ and Stage Ⅲa, respectively. His treatment was completed after 6months of adjuvant chemotherapy with oral TS-1, which was followed by a subsequent 2 year follow-up study, without disease recurrence. Operations of synchronous cancers with 2 segmental anastomoses usually require longer surgical time and are associated with more postoperative complications compared with a single segmental anastomosis. We report a case of synchronous colorectal cancer successfully treated by laparoscopic surgery with 2 segmental anastomoses.
