Abstract    Based on the concept of complete mesocolic excision, laparoscopic right hemicolectomy has become the mainstream procedure for the treatment of right colon tumor. However, due to many vascular variations in the right colon and complexity in anatomy, it is easy to cause bleeding during operation.The key to control bleeding lies in prevention, and it is the key to prevent bleeding by mastering the correct anatomical structure, familiarizing with common vascular variation, defining the correct surgical level and avoiding violent operation. Once bleeding occurs, suction and other means can be used to ensure clear surgical field. For small blood vessels bleeding or oozing, electrocoagulation, compression and other methods can be used to stop bleeding. If the main blood vessel is bleeding, it should be sutured, patch should be used or converted to laparotomy in time. Perfect preoperative imaging examination can provide intuitive data related to vascular pathway of patients and reduce the risk of bleeding.
