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.
