ObjectiveTo investigate the value of multi-disciplinary team (MDT) for the diagnosis and treatment of postoperative recurrence of hepatocellular carcinoma (HCC). MethodThe clinicopathologic data of a patient with giant HCC (66 mm×60 mm×102 mm) who was multiple intrahepatic metastases with portal vein tumor thrombus after radical resection, admitted to the Department of Hepatobiliary Surgery of Sichuan Provincial People’s Hospital, were gathered. ResultsThe patient was a middle-aged male. The multiple recurrent intrahepatic metastases combined with portal vein right branch thrombosis was found at 1 month after radical hepatectomy. After MDT discussion and evaluation, the hepatic arterial infusion chemotherapy combined with immunotherapy and targeted therapy (chemical drugs regimen was FOLFOX, immunotherapy drug was sindilizumab, targeted therapy drug was lenvatinib) was administered. After 3 times conversion therapy, and most of the intrahepatic lesions liquefied and necrotic and shrunk markedly or disappeared. After further discussion and evaluation by MDT, radical surgical resection was performed. The postoperative pathological examination results showed granulomatous inflammation with necrosis, and no exact liver cancer cells were detected. At 6 months after surgery, no tumor recurrence was observed.ConclusionsFor early recurrence combined with portal vein thrombosis after radical resection for HCC, hepatic arterial infusion chemotherapy combined with immunotherapy and targeted therapy may still be effective and even has an opporunity of surgical therapy. MDT discussion can provide the best treatment plan for patient with recurrent liver cancer, leading to a better clinical outcome for them.
Objective To investigate the application and clinical efficacy of orthotopic autologous renal transplantation combined with inferior vena cava (IVC) resection and reconstruction in retroperitoneal tumor. Methods The clinical data of a patient with complex retroperitoneal tumor was analyzed retrospectively. Abdominal CT examination showed that the tumor originated from IVC and invaded the retrohepatic IVC and bilateral renal vein trunks. Intraoperative ultrasound exploration revealed mechanized thrombosis in the IVC and bilateral renal vein trunks. After blocking the left renal vein, no significant hemodynamic changes were seen before and after intraoperative ultrasound exploration and contrast-enhanced ultrasound. Results After complete removal of the left renal vein and suture of the severed end, the right renal vein was successfully reconstructed with an orthotopic autologous right kidney graft combined with IVC resection after removal of the mechanized thrombus. The patient recovered well after surgery, and a repeat CT showed that the reconstructed artificial IVC was patent, and the color Doppler ultrasonography of both kidneys showed good perfusion and no obstruction of return. The patient was given oral rivaroxaban anticoagulant therapy after operation, and discharged at 19 days after operation. The postoperative pathological findings suggested inferior vena cava smooth muscle sarcoma. Conclusion Orthotopic autologous renal transplantation combined with IVC resection and reconstruction for complex retroperitoneal tumor is safe and feasible, and the left renal vein can be ligated and dissected intraoperatively, but a comprehensive evaluation with intraoperative ultrasound (imaging) is required.
ObjectiveTo summarize the key operative points and efficacy of ex-vivo ex-vivo liver resection and autologous liver transplantation (ELRA) using various vascular materials for hepatic vein reconstruction in the treatment of end-stage hepatic alveolar echinococcosis (HAE). MethodThe clinicopathologic data of a patient with end-stage HAE who underwent ELRA combined with complex hepatic vein reconstruction were retrospectively analyzed. ResultsThe patient was a 60-year-old male who was admitted to the Sichuan Provincial People’s Hospital due to giant alveolar hydatid in the liver, with a body weight of 60 kg and a standard liver volume of 1 024.5 mL. The imaging showed that the hydatid invaded the first and second hepatic portals, middle hepatic vein, left hepatic vein, and retrohepatic inferior vena cava. The three-dimensional reconstruction of CT showed that the residual liver volume was 1 270.6 mL. The patient received supportive treatment after admission and underwent ELRA following strict evaluation. Intraoperatively, it was found that the multiple hepatic veins and retrohepatic inferior vena cava were widely invaded. The liver was split in vivo and the mass was excised ex vivo by “in vivo first” principle. The hepatic vein was repaired and reconstructed into a wide mouth outflow tract using allogeneic veins, autologous inferior mesenteric vein, and hepatic round ligaments, then performed the autotransplantation by wide mouth outflow-artificial inferior vena cava anastomosis (end to side). The operative time was 16 h, and the intraoperative blood loss was approximately 2 000 mL. FK506 was orally administered after operation, and low-molecular-weight heparin sodium was administered 24 h later for anticoagulation. The patient was returned to the general ward on the 6th day after the operation, and the enhanced CT scan showed that the hepatic outflow tract was unobstructed, without stenosis and thrombosis, and the patient was discharged on day 18 after the operation. The patient was pathologically diagnosed with alveolar echinococcosis. ConclusionsFrom the results of this case, combination of multiple vascular materials to reconstruct the hepatic outflow tract is an optional procedure for ELRA in treatment of end-stage HAE. Strict preoperative evaluation, skillful vascular anastomosis technique, and postoperative anticoagulation are important measures to maintain patency of postoperative reconstruction vessel.
Objective To explore the effect of “in situ first” ex vivo liver resection and autologous liver transplantation (ELRA) for end stage hepatic alveolar echinococcosis (HAE). Methods The clinicopathologic data of 85 end stage HAE cases were initially scheduled underwent ELRA from June 2019 to May 2022 in the Sichuan Provincial People’s Hospital were collected retrospectively. The included cases were operated under “in situ first” ERLA principle. The analyzed data included the final surgical style, operative time, time of anhepatic phase and intraoperative blood transfusion volume for ELRA cases. Results All the included 85 cases underwent radical HAE lesions resection and without perioperative death occurred. According to the principle of “in situ first”, 57 cases underwent HAE lesions resection combined vascular reconstruction without ex vivo liver resection (in situ resection group); 1 case underwent auxiliary partial autologous liver transplantation, and 27 cases underwent ERLA procedures (ELRA group). In the in situ resection group, the operative time was 210–750 min, （380±134）min, and the intraoperative blood transfusion was 0–3 250 mL with a median of 0 mL. In the ELRA group, the operative time was 450–1 445 min, (852±203) min, and the intraoperative blood transfusion was 0–6 800 mL with a median of 1 960 mL. The operative time and the amount of blood transfusion in the ELRA group were longer or more than those in the in situ resection group. The time of anhepatic phase for the ELRA group was 60–480 min, (231±83) min. On the 5th day after operation, except that the total bilirubin and direct bilirubin in the ELRA group were higher than those in the in situ resection group, the other indexes of liver function were similar between the two groups. The postoperative stay in ICU and the total postoperative hospital stay in the ELRA group were longer than those in the in situ resection group. Conclusions The advantage of “in situ first” ERLA principle for end stage HAE patients include resecting the HAE lesions radically without ex vivo liver resection and alleviating the hepatic ischemia and reperfusion injury. For the inevasible ELRA cases, “in situ first” principle could shorten the anhepatic phase and reduce intraoperative blood loss, and turn some cases to auxiliary partial autologous liver transplantation, which will reduce the risk of postoperative hepatic failure.
