Objective To investigate the application progress of mixed reality (MR) technology in hepatobiliary and pancreatic fields. Method The relevant literatures on the application of MR technology of the hepatobiliary and pancreatic field in recent years at home and abroad were reviewed. Results MR technology had been widely used in the hepatobiliary and pancreatic field, including preoperative diagnosis and evaluation, surgical plan formulation, doctor-patient communication, intraoperative navigation precision surgery, teaching practice and many other aspects, which had the advantages of shortening the operation time, reducing the difficulty of surgery and improving the success rate of surgery. To some extent, it had promoted the innovation of clinical diagnosis and treatment in the field of liver, gallbladder and pancreas. Conclusions The application and development of MR related techniques are of great significance to the operation and teaching in the hepatobiliary and pancreatic field. With the development and progress of MR technology and modern medicine, MR technology will give full play to its advantages in intelligent real-time navigation hepatobiliary and pancreatic surgery system and promote the further development of hepatobiliary and pancreatic surgery.
