Preliminary exploration of robotic complete mesocolic excision for colon cancer with the domestically produced Chinese minimally invasive Micro Hand S surgical robot system

摘要

OBJECTIVE: To summarize our initial experience with robot-assisted complete mesocolic excision (R-CME) using a domestically produced Chinese surgical robot by a short-term evaluation. METHODS: From March 2018 to December 2018, 25 patients with colon cancer underwent Micro Hand S R-CME. The operative findings, morbidities and oncological findings were analysed. RESULT: The median operative duration was 210 (range, 180-235) min, and the median estimated blood loss volume was 55 (range, 25-125) ml. The median number of lymph nodes harvested was 42 (range, 21-77), and the median length of hospital stay after the operation was 7 (range, 5-9) days. There were no severe complications except for seven cases of grade I complications and five cases of grade II complications. The conversion rate was 0%. There were no cases of 30-day readmission or 30-day mortality. CONCLUSION: R-CME using a domestically produced surgical robot for selected colon cancer patients is technically feasible and safe.
