Quadruple advanced synchronous colorectal cancers successfully treated by laparoscopic surgery: a case report.

Among synchronous colorectal cancers (SCRCs) reported previously, the incidence of quadruple advanced SCRCs is very rare. We present the case who underwent laparoscopic two-segment resection of the colon requiring two anastomoses that was performed for quadruple advanced cancers, and four tumors were curatively removed. There were no signs of recurrence at 64 months after surgery. Laparoscopic surgery provided less invasiveness even for quadruple advanced SCRCs in terms of early recovery with an acceptable long-term outcome.
