Project description:We report the first documented case of leiomyosarcoma at zone II-III of inferior vena cava with thrombi in three hepatic veins undergoing ex vivo liver resection and autotransplantation (ELRA) and hepatic veins thrombectomy. A 33-year-old female patient presented with abdominal distention and lower extremities edema. Abdominal wall varicosis and shifting dullness were positive on physical examination. Her liver function was classified as Child-Pugh B and a solid tumor at retro-hepatic vena cava extending to right atrium with thrombi in three hepatic veins were confirmed. The diagnosis of leiomyosarcoma with Budd-Chiari syndrome was highly suspected with preoperative ultrasound, echocardiogram, CT scan, and three-dimensional reconstruction. A zone II-III leiomyosarcoma of IVC origin was confirmed at surgery and ex vivo liver resection and autotransplantation, and hepatic vein thrombectomy with atrial reconstruction were performed under cardiopulmonary bypass (CPB). Operative time, anhepatic time, and CPB time were 12 h, 128 min, and 84 min, respectively. The patients experienced post-operative liver dysfunction and was cured with conservative therapy. Hepatic recurrence two years after surgery was managed with radiofrequency. The patient was alive with liver metastasis three years after surgery. Despite being regarded as an extremely aggressive procedure, ELRA could be considered in the treatment of advanced leiomyosarcoma with Budd-Chiari syndrome and hepatic vein thrombi.

Project description:BACKGROUND:Ex situ liver resection and autotransplantation is among the most advanced techniques which has been introduced in recent years. CASE PRESENTATION:A 24-year-old male referred with chief complaints of abdominal pain, nausea, and vomiting from 1 month prior to admission. Computed tomography showed a large liver mass in the left lobe of the liver with involvement of retrohepatic inferior vena cava (IVC), in favor of hepatocellular carcinoma. After hepatectomy, the common bile duct was completely removed. A 4-cm Dacron graft was anastomosed to the inferior and top of the IVC. A temporary portocaval shunt was placed, and ex situ resection of the left lobe of the liver was done. Remnant of the liver was implanted. Reconstruction of the bile duct was done using a Roux-en-Y technique, and autotransplantation of the liver was then completed. During a 4-year follow-up, the patient had no complaints and is in good conditions. CONCLUSION:With appropriate consideration of patients, despite surgical complexities, ex situ resection of unresectable HCC can provide excellent prognosis.

Project description:BackgroundRetrohepatic inferior vena cava (RIVC) resection without reconstruction in ex vivo liver resection and autotransplantation (ERAT) for advanced alveolar echinococcosis (HAE) is unclear.MethodsThis is a retrospective study of consecutive patients referred to our hospital from 2014 to 2018. Depending on the presence of a rich collateral circulation and stable blood volume in ERAT, patients did not rebuild the RIVC. Then, patients were selected some appropriate revascularization techniques for the hepatic and renal veins. Finally, all ERAT procedures were completed, and short- and long-term outcomes were observed.ResultsFive advanced HAE patients underwent ERAT without RIVC reconstruction. One patient died of circulatory failure 1 day after surgery. Another four patients, with a median follow-up duration of 18 months (range, 10-25 months), demonstrated normal liver and kidney function, no thrombosis and no HAE recurrence.ConclusionsThrough the long-term results of ERAT, the pros and cons of not reconstructing the RIVC need to be re-examined. In cases with a rich collateral circulation, the RIVC cannot be reconstructed. However, in cases requiring the resection of multiple organs, RIVC without reconstruction was prudential.

Project description:RationaleThere has been increased use of ex vivo liver resection and autotransplantation (ERAT) for treatment of end-stage hepatic alveolar echinococcosis (HAE). Rapid perfusion of the autograft in bench resection is always required to reduce the warm ischemia time (WIT) and to protect the function of the remnant liver. Nevertheless, the severe invasion of the portal hepatis sometimes makes it impossible to find a usable inflow rapidly and the process of perfusion could be delayed.Patient concernsTwo patients diagnosed with end-stage HAE combined with severe portal hepatis invasion were selected to undergo ERAT at our center.DiagnosisBesides the large HAE lesions, the CT imaging of patient 1 showed that part of the intra- and extrahepatic portal vein (PV) had disappeared. Patient 2 had severe invasion of both of the right and left branches of the PV.InterventionsWe introduced a new approach for perfusing the liver in ERAT using transhepatic-intrahepatic branches of the PV catheterization. Afterward, ERAT was successfully performed.OutcomesFor patient 1, the WIT was 2 minutes and the cold ischemia time (CIT) was 296 minutes. For patient 2, the WIT was 2 minutes and the CIT was 374 minutes. Patient 1 suffered stenosis of the common bile duct on postoperative day 14, and patient 2 recovered uneventfully. Both of the 2 patients were discharged from the hospital with normal laboratory values on postoperative day 31 and 15, respectively. The laboratory values for both patients at recent follow-up were normal.LessonsTranshepatic-intrahepatic branches of the PV catheterization is useful for decreasing WIT and facilitating the management of ERAT. It is a useful technical variant that could be used in ERAT for treating patients with severe portal hepatis invasion.

Project description:A solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Ex situ hepatectomy and liver autotransplantation are novel methods for the treatment of complicated liver tumors, for example, those involving vascular structures, including the inferior vena cava, which are unresectable by conventional approaches. The present study describes a rare case of a massive hepatic SFT in a 32-year-old female who underwent ex situ hepatectomy and liver autotransplantation to achieve a radical resection. The surgery was without complications. Post-operative histopathological and immunohistochemical examinations revealed an SFT of the liver. The patient was discharged 29 days after the surgery with fully recovered liver function. The routine check-up 3 months after surgery indicated normal liver function and no evidence of recurrence. Additionally, an exhaustive review of available literature was performed to provide a complete overview of the current status of SFTs. In summary, the present study found that ex situ hepatectomy and liver autotransplantation are suitable surgical techniques for treating a giant SFT, as well as other liver neoplasms that are considered unresectable by conventional surgery.

Project description:Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end-stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This article aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality. The median weight of the autografts was 636 g (360-1300 g), the median operation time was 12.5 hours (9.4-19.5 hours), and the median anhepatic phase was 309 minutes (180- 460 minutes). Intraoperative blood loss averaged 1800 mL (1200-6000 mL). Postoperative complications occurred in 13 patients during hospitalization; 5 patients experienced postoperative complications classified as Clavien-Dindo grade III or higher, and 2 patients died of intraabdominal bleeding and acute cerebral hemorrhage, respectively. Twenty-nine patients were followed for a median of 14.0 months (3-42 months), and no HAE recurrence was detected. The technique requires neither an organ donor nor any postoperative immunosuppressant, and the success of the treatment relies on meticulous preoperative assessments and precise surgical manipulation.

Project description:Ex vivo surgery and autotransplantation may provide a promising option for radical resection of conventionally unresectable liver tumors. Two cirrhotic patients with hepatocellular carcinoma (HCC), which has an "awkward seat" located in the "intrahepatic vascular triangle area (IVTA)" that consists of the middle hepatic vein (MHV), the right branches of the Glisson sheath, and the inferior vena cava (IVC), underwent in vivo extended right-half hepatectomy followed by ex vivo tumor resection and partial liver autotransplantation. Innovatively, the outflow of the tumor-free liver was reconstructed ex vivo using pre-frozen allograft blood vessels from brain-dead donors; the patients recovered well postoperation. We report the surgical experience to provide a novel curable surgical procedure for locally advanced IVTA liver tumors.

Project description:BackgroundAlveolar echinococcosis (AE) primarily affects the liver and potentially spreads to other organs. Managing recurrent AE poses significant challenges, especially when it involves critical structures and multiple major organs.Case presentationWe present a case of a 59-year-old female with recurrent AE affecting the liver, heart, and lungs following two previous hepatectomies, the hepatic lesions persisted, adhering to major veins, and imaging revealed additional diaphragmatic, cardiac, and pulmonary involvement. The ex vivo liver resection and autotransplantation (ELRA), first in human combined with right atrium (RA) reconstruction were performed utilizing cardiopulmonary bypass, and repairs of the pericardium and diaphragm. This approach aimed to offer a potentially curative solution for lesions previously considered inoperable without requiring a donor organ or immunosuppressants. The patient encountered multiple serious complications, including atrial fibrillation, deteriorated liver function, severe pulmonary infection, respiratory failure, and acute kidney injury (AKI). These complications necessitated intensive intraoperative and postoperative care, emphasizing the need for a comprehensive management strategy in such complicated high-risk surgeries.ConclusionsThe multidisciplinary collaboration in this case proved effective and yielded significant therapeutic outcomes for a rare case of advanced hepatic, cardiac, and pulmonary AE. The combined approach of ELRA and RA reconstruction under extracorporeal circulation demonstrated distinct advantages of ELRA in treating complex HAE. Meanwhile, assessing diaphragm function during the perioperative period, especially in patients at high risk of developing pulmonary complications and undergoing diaphragmectomy is vital to promote optimal postoperative recovery. For multi-resistant infection, it is imperative to take all possible measures to mitigate the risk of AKI if vancomycin administration is deemed necessary.

Project description:BackgroundApproximately 50% of patients with colorectal cancer (CRC) develop metastases most commonly in the liver. Liver transplantation (LT) can be used in certain cases of primary liver malignancy or in metastatic diseases, such as Neuroendocrine tumors. However, there are controversies regarding LT as a treatment option for liver metastasis from CRC due to poor outcomes in previously reported cases.Case presentationWe report a 37-year-old male who underwent resection of the left-sided colon due to cancer and was found to have synchronous liver metastasis for which he received chemotherapy. Later, he underwent a right hepatectomy, which was complicated by insufficient liver remnant function despite the preserved liver perfusion. Therefore, salvage liver transplantation was performed successfully with a good long-term outcome.ConclusionsMany studies examined the survival and quality of life in patients undergoing liver transplantation for unresectable colorectal liver metastasis; these studies include the SECA Study (secondary cancer) and others with favorable outcomes. We reviewed the literature and compared the outcomes of some of these studies in this article. Our case emphasizes that liver transplantation could be an option for some colon cancer liver metastasis (CLM) patients, specifically, as a salvage procedure. Thus, more research is needed to develop selection criteria for patients who may benefit from liver transplantation.
