ObjectiveTo summarize the surgical technique and indications for liver masses involving the second and the third porta hepatis.MethodsThirteen cases of liver mass involving the second and the third porta hepatis, who underwent surgery in West China Hospital of Sichuan University from June 2013 to September 2016 were collected retrospectively, then made a statistical analysis, including patients’ information, characteristics of liver masses, operation information, and result of followed-up.ResultsOf the 13 cases, there were 3 cases of hepatic alveolar echinococcosis, 4 cases of hepatocellular carcinoma, 4 cases of intrahepatic cholangiocarcinoma, and 2 cases of liver metastasis induced by colon cancer. The mean tumor diameter was 12.5 cm (7–21 cm). Preoperative imaging examinations showed that mass had involved the second and the third porta hepatis, and all masses were resected by surgery without perioperative death, including 7 cases of right three hepatectomy resection, 1 case of left three hepatectomy resection, 4 cases of right hepatectomy resection, and 1 case of left hemi hepatectomy resection; among them, 9 cases were performed caudal lobectomy resection. The mean of operative time was 313 min (210–450 min), the mean of intraoperative blood loss was 592 mL (300–1 100 mL). Four cases received blood transfusion with 300–450 mL (mean of 338 mL). The total hepatic blood inflow occlusion time was 25–55 min (mean of 42 min). Five cases received venous reconstruction, and 1 case received hepatic vein reconstruction. After operation, ascites occurred in 6 cases, pleural effusion occurred in 6 cases, liver failure occurred in 2 cases, bile leakage occurred in 2 cases, pulmonary infection occurred in 3 cases, deep vein thrombosis occurred in 1 case. All of the 13 cases were followed-up for 1–39 months (median time was 14 months), during the followed-up period, 4 cases died, including 3 cases of intrahepatic cholangiocarcinoma and 1 case of liver metastasis induced by colon cancer.ConclusionIt is encouraging to apply the vascular reconstruction and skilled hepatic partition technique for resection lesions which involved the second and the third porta hepatis, through meticulous preoperative evaluation and preparation.
Objective To evaluate the safety and efficacy of surgical resection for the second and the third hepatic portal tumor. Methods The clinical data of 39 patients who underwent surgical resection of the second and the third hepatic portal tumor were analyzed from May 2012 to May 2017 in our hospital. Among them, there were 29 patients with primary liver cancer, 6 patients with hepatic hemangioma, 2 patients with focal liver hyperplasia, and 2 patients with liver metastasis from colon cancer. Results Right liver resection was performed in 11 patients, left liver resection in 7 patients, left outer lobe resection in 6 patients, right trefoil excision in 5 patients, Ⅴand Ⅷ segment resection in 4 patients, Ⅶ and Ⅷ segment resection in 4 patients, local resection in 2 patients. In the resection, there were 16 patients without interruption of hepatic inflow, 21 patients with interrupted portal blood flow, 2 patients with total hepatic blood flow occlusion. The operative time of the 39 patients was 150–270 min (mean of 190 min), the intraoperative blood loss was 100–2 000 mL (mean of 680 mL). Postoperative bile leakage occurred in 2 patients, bleeding occurred in 1 patient, and no liver failure occurred. Twenty-six patients were followed-up of 31 liver cancer patients, and the follow-up time was 3–40 months, the median time was 8 months. During follow-up period, 12 patients died, 9 patients died of tumor recurrence, 3 patients died from liver failure. Of 8 patients, 5 patients with benign liver disease were followed-up for 7–18 months with living healthy, and the median time was 9 months. Conclusion The risk of surgical resection of tumors invaded the second and the third hepatic portal is mainly the accurate functional assessment of residual liver and the correct treatment of the main branches of the hepatic veins.
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.
