This operation was performed by laparoscopic right hemicolectomy. The blood vessels were dissected through the central approach，and the lymph nodes near the trunk were dissected. The liver curvature of the colon was dissociated at the head side，and the right hemicol was lifted through the caudal approach. The corresponding blood vessels of the right hemicol were well separated and the lymph nodes were dissected，especially the Henle stem. The operation time was 60 minutes long，and there was no acceleration after video editing，which could basically reflect the details of the whole procedure of the operation. There was almost no bleeding in the standard surgical approach. The operation and suture under the endoscope were smooth，and the highlights of the operation process included vascular anatomy，lymph node dissection，and intracavitary closure of mesentery.
