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.

To investigate the mRNA expression of nm23-H1 gene in human liver tumor. In tumor and corresponding nontumoral liver specimens from 20 patients, nm23-H1 mRNA were examined by reverse transcriptionpolymerase chain reaction (RT-PCR) method with specific primers. Results: The primers designed in this study could amplified nearly entire coding sequence of nm23-H1 gene. All the samples showed positive expression of nm23-H1 mRNA, indicating there was no expression loss or obvious alteration. Conclusions: The achievement of RT-PCR method lays foundation for quantitative gaugement of nm23-H1 mRNA in liver tumor.
ObjectiveTo investigate the application value of totally laparoscopic associating liver tourniquet and portal ligation for staged hepatectomy (ALTPS) using the anterior approach technique for hepatocellular carcinoma (HCC) with hepatitis B cirrhosis. MethodsIn September, 2014, a patient suffered cirrhotic hepatocellular carcinoma in the right liver scheduled for two-stage liver resection, in whom the future liver remnant (FLR) was considered too small (FLR/standard liver volume:29.1%, FLR/body wight:0.49%). In the first stage, using totally laparoscopic technique, a tourniquet was placed around the parenchymal transection line on the Cantlie's line via an anterior approach through retrohepatic tunnel for staged right hepatectomy, and the right portal vein was ligated. In the second stage, totally laparoscopic right hemihepatectomy was carried out on 10 days after the first-stage operation that achieved sufficient hypertrophy of the FLR. ResultsThe FLR on postoperative day 4 of the first stage increased from 301.48 to 496.45 mL (FLR/standard liver volume:47.9%, FLR/body wight:0.81%), with a 64.67% hypertrophy. And the FLR on postoperative day 8 of the first stage increased to 510.96 mL (FLR/standard liver volume:49.3%, FLR/body wight:0.84%), with a 69.48% hypertrophy. The remnant liver volume on postoperative day 5 of the second stage increased to 704.53 mL. The duration of the first stage was 180 min, intraoperative blood loss was 50 mL, and patient did not received a blood transfusion. The duration of the second stage was 220 min, intraoperative blood loss was 400 mL, and patient did not required a blood transfusion. No serious complications happened. The patient was discharged on 7 days after the second stage. ConclusionsAs a effective, safe, simple, and "non-touch" technique which provided a less aggressive modification of the ALPPS procedureto achieve oncological efficacy, the totally laparoscopic ALTPS using the anterior approach technique also could achieve sufficient hypertrophy of the FLR in several days. A proper expansion of the indications for the procedure is safe and feasible in HCC patients with cirrhosis.
ObjectiveTo investigate the safety and feasibility of fluorescent guided laparoscopic central hepatic tumor resection via anterior transhepatic approach. MethodWe retrospectively analyzed the clinical data of three patients who underwent fluorescent guided laparoscopic central hepatic tumor resection via anterior transhepatic approach in Department of Hepatobiliary and Pancreas Minimally Invasive Surgery of Hunan Provincial People’s Hospital from April 2017 to April 2020.ResultsAll the three patients completed the operation pure laparoscopically. Pathology results showed one case of hepatocellular carcinoma and two cases of focal nodular hyperplasia, the tumor size range from 4–7 cm. The operation time was 240–320 min, and the blood loss was 150–500 mL. There was no intraoperative blood transfusion. The postoperative hospital stay was 10–30 days. Postoperative bile leakage occurred in one patient, which was cured by laparoscopic hepatectomy. Three patients were followed up for 8, 36, and 25 months, respectively, and all the patients survived and there was no tumor recurrence up to november 2020.ConclusionsLaparoscopic resection of central hepatic tumor is difficult and risky. Anterior transhepatic approach can maximize the preservation of liver parenchyma. In hepatobiliary and pancreatic centers with high volume of laparoscopic hepatectomy, this method is safe and feasible after strict patient selection, accurate preoperative evaluation, and fine intraoperative skills. Indocyanine green fluorescence navigation technology is helpful to accurately locate tumor during operation.
ObjectiveTo summarize the experiences of precise liver resection for giant complex hepatic neoplasm. MethodsFifty-two cases of giant complex hepatic neoplasms were resected using precise liver resection techniques from April 2008 to August 2009. Hepatic functional reserve and liver imaging were evaluated before operation. Appropriate surgical approach, halfhepatic blood flow occlusion, new technique of liver resection, and intraoperative ultrasonography were applied during operation. ResultsThe mean operative time, halfhepatic blood occlusion time, blood loss, recovery of alanine aminotransferase, and total bilirubin were 350 min (210－440 min), 43 min (8－57 min), 370 ml (250－1 150 ml), 10 d (7－14 d), and 4.5 d (3－10 d), respectively. Only 6 patients had mild bile leakage. No liver failure and other major complications emerged, and no death happened. ConclusionPrecise liver resection is a safe and effective approach for giant complex hepatic neoplasm.
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.
