[Robot-Assisted Surgery for Stage Ⅳ Gastric Cancer with Liver Metastases-Report of a Case].

We report a successful case of robot-assisted surgery for Stage Ⅳ gastric cancer with liver metastasis. A 70s man diagnosed with advanced gastric cancer with S3 solitary liver metastasis, and received a chemotherapy with S-1 and cisplatin. After 4 courses of chemotherapy, liver metastatic lesion was disappeared. Thus, robotic distal gastrectomy and partial liver resection were performed. Operating time was 391 minutes, and amount of intraoperative blood loss was 11 mL. The postoperative course was uneventful, and the patient was discharged 11 days after surgery. Histologic examination revealed no viable malignant cells in the resected liver, with a diagnosis of ypT2N1M0, ypStage ⅡA. The patient is alive with no recurrence 12 months after surgery, without adjuvant chemotherapy.
