This paper describes the advantages and disadvantages of radiofrequency ablation from the current situation of hepatocellular carcinoma treatment, radiofrequency ablation treatment, the efficacy of radiofrequency ablation in hepatocellular carcinoma, the shortcomings of radiofrequency ablation treatment, and the experience of the author’s treatment team. For the treatment of liver cancer, we should not blindly pursue minimally invasive and ignore the principle of radical resection, nor blindly pursue radical resection and ignore the risk of surgery. We should choose reasonable treatment methods, let the patient get the best treatment.
Objective To summarize the diagnosis and treatment for primary hepatic neuroendocrine carcinoma. Methods The clinicopathologic data of three patients with primary hepatic neuroendocrine carcinoma from June 2010 to June 2011 in this hospital were analyzed retrospectively. Results Three cases were difficult to diagnose primary hepatic neuroendocrine carcinoma before operation. All the treatments were resection. Three patients were diagnosed as neuroendocrine carcinoma by pathology and immunohistochemistry after operation. All of them were treated by octreo-tide after operation and discharged from hospital successfully. There was no relapse one year later. At present， 3 patients were still continue to follow-up. Conclusions The diagnosis of primary hepatic neuroendocrine carcinoma is very difficult before operation， the assessment of treatment and curative effect is exploring.
Objective To explore favorable factors of reducing incidence of postoperative liver failure after radical resection of Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma in condition of hyperbilirubinemia. Methods All the clinical data of one patient with Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma underwent radical resection in June 2017 in the West China Hospital of Sichuan University were collected. The preoperative total bilirubin level of this patient was 470.3 μmol/L, the patient didn’t receive preoperative biliary drainage. The preoperative jaundice time and cholangitis were calculated accurately. A 3D imaging system for quantitative evaluation of the liver was used to reconstruct the images with contrast-enhanced CT images of this patient. And the total liver volume and the future liver remnant volume (FLRV) were calculated. Finally, 6 months of follow-up were conducted after surgery. Results The exact jaundice time was 20 d and there was no preoperative cholangitis. The postoperative FLRV accounted for about 70%. No postoperative liver failure occurred. No recurrence of tumor and death of patient occurred after 6 months of follow-up. Conclusions Radical resection of hilar cholangiocarcinoma in condition of hyperbilirubinemia is not an absolute contraindication for surgery, but indications should be strictly controlled. For special patient whose jaundice with short duration, no preoperative cholangitis and a high FLRV may be treated with directly radical surgery to prevent for losting the best time of surgery.
ObjectiveTo explore the efficiency of two-stage hepatectomy applicated in complex alveolar echinococcosis. MethodThe clinical data of one case who suffered from complicated alveolar echinococcosis with multiple lesions and then treated with two-stage hepatectomy were analyzed retrospectively. ResultsPreoperative enhanced CT revealed that the hydatid lesion with irregular shape, measuring 14.1 cm×9.2 cm, invaded several segments including left medial lobe and right anterior lobe of liver and the right branch of portal vein and medium hepatic vein were entirely surrounded by it. After preoperative examination surgical exploration was performed, two larger lesions measuring 6 cm×5 cm×4 cm and 5 cm×4 cm×4 cm respectively were found in caudate lobe of liver, three smaller lesions were found in the right and left lobe of liver, among which two measured 2 cm×2 cm×1 cm in the right lobe and one measured 3 cm×2 cm×1 cm in the left lobe. Mesohepatectomy was performed in the first stage, the lesion in left medial lobe and right anterior lobe of liver and the right anterior branch of portal vein were resected during the procedure. The patient recovered well after the operation without complications such as bile leakage or hemorrhage observed. The second stage surgery was performed at three months after operation, the computed tomograph before the surgery revealed that the remained lesions in the right lobe of liver did not proceed obviously and the left lateral external lobe of liver regenerated significantly. In the second stage, the right anterior lobe and part of the right posterior lobe of liver were resected. The patient was discharged on 7 days after operation, and there was no complication and relapse during the 7 months of follow-up period. ConclusionTwo-stage hepatectomy applicated in treating complicated alveolar echinococcosis with multiple lesions is safe and feasible, offering a choice with smaller trauma, lower expense and less complications for patients compared with liver transplantation.
