[Simultaneous Resection of Sigmoid Colon Cancer and Synchronous Liver Metastasis by Laparoscopic Surgery]

We report the case of a patient with sigmoid colon cancer with synchronous liver metastasis who underwent simultaneous sigmoid colectomy and partial hepatectomy by laparoscopic surgery. A 70-year-old man with positive fecal occult blood was diagnosed with sigmoid colon cancer and referred to our hospital. Staging computed tomography (CT) revealed a solitary liver metastasis in segment 6, confirmed by magnetic resonance imaging (MRI). He underwent simultaneous laparoscopic sigmoid colectomy and partial hepatectomy. The patient's postoperative recovery was uneventful and he was discharged 12 days later. The patient was alive without recurrence 4 months after surgery. Laparoscopic surgery is an accepted mode of treatment for colorectal cancer. However, the use of laparoscopy in liver surgery is still limited. There have only been few case reports of combined laparoscopic colorectal and liver resection. Simultaneous laparoscopic colectomy and hepatectomy is feasible for selected colorectal cancer patients with liver metastases. It may provide significant decrease in morbidity, length of hospitalization time, and intraoperative blood loss, without compromising curability or increasing mortality. Further studies are needed to confirm the feasibility of this approach.
