本手术为腹腔镜下右半结肠切除术式，中央入路解剖血管、清扫主干旁淋巴结，头侧游离结肠肝曲，尾侧入路掀起右半结肠，将右半结肠相应血管离断、淋巴结清扫展示出来，尤其是处理Henle干。手术时间总长约60 min，视频剪辑后无加速，基本能反映出手术全程步骤的各个细节，全程手术层次入路标准，几乎无出血。腔镜下操作及缝合动作流畅，手术流程亮点包括血管解剖、淋巴结清扫、腔内关闭系膜。

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.
