ObjectiveTo investigate the feasibility of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) combined with mixed reality holographic imaging in treating the massive hepatocellular carcinoma.MethodThe clinicopathologic data of 1 patient with massive hepatocellular carcinoma underwent the ALPPS combined with mixed reality holographic imaging in the Guangdong Second Traditional Chinese Medicine Hospital on January 2019 were retrospectively analyzed.ResultsA 58-year-old female patient, the preoperative CT scan and enhanced scan of the abdomen revealed a 12.0 cm×10.5 cm×17.0 cm mass in the right lobe of the liver, with preoperative Child-Pugh grade A liver function. The ALPPS was performed after the preoperative evaluation. The associating liver partition and portal vein ligation was performed and the mixed reality holographic imaging was used during the stage Ⅰ operation. On day 21 after the stage Ⅰ operation, the CT results of the volume of left lateral lobe of liver was approximately 57.64%. On day 24 after the stage Ⅰ operation, the patient underwent the stage Ⅱ operation (radical hepatectomy). The patient received the chemotherapy after the operation. The courses of those operations were successful. And no severe complications occurred after the operation. The postoperative pathological results showed a moderately differentiated hepatocellular carcinoma with multiple foci and a maximum diameter of 13 cm. Six months after the last operation, there was no new intrahepatic metastasis and other metastases were found.ConclusionsALPPS combined with mixed reality holographic imaging is effective in treatment of massive hepatocellular carcinoma. Mixed reality holographic imaging could show anatomical details with three dimensions, it is beneficial for estimating future liver reserve before operation and locating during operation, and there is also a positive significance of postoperative recovery.
ObjectiveTo summarize the research progress of mixed reality (MR) technology in the field of vascular surgery.MethodWe retrieved the literatures about the application of MR technology in vascular surgery, and summarized and analyzed them.ResultsThe application of MR technology in vascular surgery could greatly improve the standardization of medical education, shorten the learning cycle, effectively shorten the operation time, and increase the benefit of patients. The application of MR in vascular surgery was still in its infancy, and it showed some attractive prospects as well as some shortcomings.ConclusionsThe application of MR technology in vascular surgery is still at the exploratory stage, but it has an attractive prospect. With the continuous improvement of registration technology and the continuous improvement of accuracy, MR technology will be more and more widely used in vascular surgery.
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.
