    Abstract:
    BACKGROUND: A laparoscopic approach is increasingly being utilized in simultaneous colorectal and liver resection (SCLR) for colorectal cancer with liver metastasis. However, this approach is technically challenging and hence has not been widely adopted. Robotic surgical systems could potentially overcome this problem. We aim to describe the feasibility and outcomes of robotic SCLR for colorectal carcinoma with liver metastasis. METHODS: The medical records of 12 patients who underwent robotic SCLR for colorectal cancer with liver metastasis between January 2008 and September 2018 were reviewed retrospectively. RESULTS: The mean age was 59 years (range, 37-77 years). The liver resections were comprised of two right hepatectomies, one left hepatectomy, one left lateral sectionectomy, one segmentectomy of S3 and wedge resection (segment 7), one caudate lobectomy, one associated liver partition and portal vein ligation for staged hepatectomy, and five wedge resections involving segments 4, 5, 6, 7, or 8. The colorectal procedures involved seven low-anterior resections, two anterior resections, two right hemicolectomies, and one left hemicolectomy. The mean operative time was 449 min (range, 135-682 min) with a mean estimated blood loss of 274.3 mL (range, 40-780 mL). The mean length of hospital stay was 12 days (range, 5-28 days). No patients required conversion to laparotomy. Liver resection-related complications were two liver abscesses (Clavien-Dindo classification, one grade II and one grade III) and one case of ascites (grade I), whereas colorectal resection-related complications included one anastomosis leak (grade III) and one superficial wound infection (grade II). There were no deaths reported within 30 days of the procedure. With a mean follow-up duration of 31.5 ± 26.1 months, the overall survival and disease-free survival values were 75.2 and 47.1 months, respectively. CONCLUSION: Robotic SCLR for colorectal neoplasm with liver metastasis can be performed safely even in cases requiring major liver resections, especially in a specialized center with a well-trained team.
