Recently, the Department of Oncology of the General Hospital of the Chinese People’s Liberation Army successfully completed a robotic right hemicolectomy + right hemicolectomy, which has not been reported worldwide according to literature search. It is reported that the patient is a middle-aged male, diagnosed with malignant tumor of transverse colon and hepatic flexure with right liver metastasis, and the conventional open surgery requires two incisions, one in the middle of the right side (about 15cm long) and one under the right rib margin (about 25cm long), which is very traumatic and unfavorable for postoperative recovery. The patient was able to get out of bed on the first day after the operation and recovered smoothly after the operation and was discharged on the 8th day. Colorectal cancer is one of the longest malignant tumors in China, and about 50% of patients will have liver metastasis. The traditional view is that colorectal cancer with liver metastasis is advanced and not suitable for surgery. However, the traditional open surgery requires a huge incision on the abdomen from the pubic symphysis or multiple incisions, which is complicated and brings huge physical and psychological trauma to the patients. The da Vinci robotic surgical operating system is the first device caused by PLA General Hospital in China, which has the advantages of flexible and stable operation and three-dimensional view compared with traditional laparoscopic surgery, and is more suitable for complex and difficult surgery. The PLA Oncology Center has set up a multidisciplinary treatment collaboration group for colorectal cancer since 2009, which can formulate individualized sequential treatment plans for patients. The Department of Oncology Surgery has set up several specialties such as gastrointestinal, hepatobiliary, etc. Two professors, Jia Baoqing and Liu Rong, who are leaders of the department, have many years of experience in minimally invasive surgery, and it is understood that through close collaboration, they have completed stage I resection of liver metastasis from colorectal cancer more than 20 cases. The successful completion of right hemicolectomy combined with right hemicolectomy fills a gap in the field of minimally invasive robotic surgery in the world and marks that the domestic robotic surgery technology is at the forefront of the world.
