ABSTRACT
Objective:To evaluate the clinical efficacy and safety of ex vivo liver resection and autotransplantation (ELRA) by using a Bayesian single-arm Meta-analysis.Methods:Databases of PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang were searched from January 1, 1990 to December 30, 2021 on ELRA studies. The Bayesian one-arm Meta-analysis was performed by using the statistical software of R (V4.1.2) and the Markov chain-Monte Carlo method was used to simulate the posterior distribution. The mortality rate within 30 days after operation, 1-year survival rate, major postoperative complications, R 0 resection rate and other related indexes were analyzed. Results:A total of 20 studies with 436 patients were included. Bayesian single-arm Meta-analysis showed that the 1-year survival rate after ELRA was 83.24% [95% highest posterior density ( HPD): 72.40%-92.05%]. The 1-year survival rates after surgery were 88.66% (95% HPD: 81.52%-94.50%) for patients with hepatic alveolar echinococcosis and 61.29% (95% HPD: 38.53%-93.68%) for patients with hepatic malignancies, respectively. The mortality rate within 30 d after surgery, the incidence of significant postoperative complications, and the R 0 resection rate were 6.96% (95% HPD: 4.47%-10.15%), 27.91% (95% HPD: 19.00%-38.30%), and 99.84% (95% HPD: 37.61%-100.00%), respectively. Renal failure was the most frequent cause of death after ELRA. Conclusion:ELRA is indicated for hepatic malignancies and hepatic alveolar echinococcosis when intrahepatic resection cannot be accomplished in vivo. The greatest benefit is observed in patients with hepatic alveolar echinococcosis, while only some patients with hepatic malignancies can benefit. The indications for ELRA for hepatic malignancies need to be further studied to define the subgroup of patients who can benefit from this operation.
ABSTRACT
Objective To detect the expression of transforming growth factor-β1 (TGF-β1), p38MAPK and bone morphogenetic protein-7 (BMP-7) protein in the liver specimens of patients with hepatic alveolar echinococcosis, and to investigate the potential role of TGF-β1, p38MAPK and BMP-7 protein in hepatic fibrosis caused by hepatic alveolar echinococcosis. Methods A total of 20 patients with hepatic alveolar echinococcosis were enrolled as study subjects, and hepatic specimens were sampled from the sites within 0.5 cm (Group A) and 0.5 to 1.5 cm from hepatic alveolar echinococcosis lesions (Group B), while normal liver specimens sampled from the sites 2 cm and greater from hepatic alveolar echinococcosis lesions served as controls (Group C). The fibrosis of liver specimens was pathological examined using HE and Masson staining, and the expression of TGF-β1, p38MAPK and BMP-7 protein was quantified in liver tissues using Western blotting. The associations of TGF-β1, p38MAPK and BMP-7 protein expression with hepatic fibrosis were assessed. Results HE staining showed the malaligned structure of hepatocytes and destruction of the structure of hepatic lobules at various degrees in liver specimens in groups A and B, with hepatocyte degeneration, atrophy and necrosis, hyperplasia of fibrous tissues and eosinophilic granulocyte infiltration seen, while no abnormal pathological alterations of liver tissues, normal hepatocyte structure and morphology and uniform size, no malaligned structure of hepatocytes, clear structure of hepatic lobules, no or mild hepatocyte degeneration or necrosis, and no eosinophilic granulocyte infiltration were seen in Group C. Masson staining showed that there was hyperplasia of multiple fibrous connective tissues in the liver portal areas in groups A and B, with fibrosis seen in hepatic lobules, while no obvious pathological changes were seen in Group C. There were significant differences seen in TGF-β1 (P < 0.001), p38MAPK (P < 0.01) and BMP-7 protein (P < 0.05) expression in liver tissues in groups A, B and C, and higher TGF-β1, p38MAPK and BMP-7 protein expression was quantified in groups A and B than in Group C (all P values < 0.05), while greater TGF-β1, p38MAPK and BMP-7 protein expression was detected in Group B than in Group C (all P values < 0.05). The expression of TGF-β1, p38MAPK and BMP-7 protein correlated positively with the severity of hepatic fibrosis (r = 0.866, 0.702 and 0.801, all P values < 0.05), and there were significant differences in TGF-β1 (F = 72.580, P < 0.01), p38MAPK (χ2 = 31.705, P < 0.01) and BMP-7 protein expression (χ2 = 48.388, P < 0.01) among liver tissues with different degrees of fibrosis. The TGF-β1 protein expression correlated positively with p38MAPK and BMP-7 protein expression (r = 0.607 and 0.702, both P values < 0.001), and the BMP-7 protein expression also correlated positively with p38MAPK protein expression (r = 0.456, P < 0.001). Conclusion The interaction among TGF-β1, p38MAPK and BMP-7 jointly participates in the development of hepatic fibrosis induced hepatic alveolar echinococcosis.
ABSTRACT
The patients with hepatic alveolar echinococcosis have unapparent early symptoms due to invasive and slow growth, and the disease is usually at an advanced stage upon diagnosis, which has a poor prognosis. Early diagnosis of hepatic alveolar echinococcosis is therefore of great importance. The advances in the ultrasound techniques continues to improve the accuracy for the diagnosis of hepatic alveolar echinococcosis, and ultrasound plays a critical role in the treatment and assessment of therapeutic efficacy for hepatic alveolar echinococcosis. This paper mainly reviews the application of ultrasound in the diagnosis and treatment of hepatic alveolar echinococcosis.
ABSTRACT
Alveolar echinococcosis is a parasitic zoonosis that severely damages human health. Currently, radical surgical resection is the first choice for hepatic alveolar echinococcosis. For the advanced hepatic echinococcosis patients with refractory radical resection, the palliative surgery combined with chemotherapy, liver transplantation, drug therapy, and radiofrequency microwave ablation may provide comprehensive tools. This article reviews the current situation and progress of comprehensive treatments for hepatic alveolar echinococcosis.
ABSTRACT
Objective To investigate the clinical characteristics of patients with advanced hepatic alveolar echinococcosis, so as to provide more evidence for the diagnosis and treatment of advanced hepatic alveolar echinococcosis. Methods The clinical records of 175 cases with hepatic alveolar echinococcosis admitted to the Affiliated Hospital of Qinghai University from 2012 to 2017 were retrospectively reviewed. Results Among the 175 cases with hepatic alveolar echinococcosis, the male to female ratio was 1∶1.6, and the mean age was (38.6 ± 12.9) years (range, 11 to 69 years). 93.7% of the patients (164 cases) were Tibetan, and 79.4% (139 cases) were from Guoluo Prefecture. 73.7% (129 cases) were herdsmen, and 58.3% (102 cases) were illiterate. The major clinical symptoms included upper abdominal pain, yellowing of skin and mucosa, and scleral icterus. 69.1% of the lesions were located in bilateral livers, and 63.4% of the cases have 2 and more lesions. 53.7% of the cases have their inferior vena cava involved by the lesions. In addition, the most affected neighboring organ was diaphragmatic muscle (21.7%), and lung was the most affected distant metastatic site (40.6%). Conclusions Advanced hepatic alveolar echinococcosis is highly prevalent in Guoluo Prefecture, Qinghai Province. Screening of this disease is required in this region and rational treatment scheme should be developed.

ABSTRACT
Objective To analyze the blood supply and metabolism in the marginal area of foci of hepatic alveolar echinococcosis by quantitative perfusion parameters. Methods Thirty patients with hepatic alveolar echinococcosis were scanned with the Revolution CT and the images were analyzed. The perfusion parameters, such as the bloodflow (BF), time to peak (TTP), blood volume (BV), mean transit time (MTT) and hepatic arterial fraction (HAF) were compared among different groups. Results The BF, TTP, BV and MTT values of the peripheral infiltration zone and the values of the surrounding normal liver tissues were significantly different (F = 24.579, 8.343, 20.535 and 21.843, all P<0.05), but the HAF values of the peripheral infiltration zone and the values of the surrounding normal liver tissues were not significantly different in the hepatic alveolar echinococcosis patients (F = 2.621, P> 0.05) . Conclusion The whole hepatic perfusion Revolution CT can accurately and quantitatively analyze the alveolar echinococcosis foci, especially the peripheral infiltration zone, which has important guiding significance for the formulation of surgical plan.
ABSTRACT
Objective To evaluate the value of the three-dimensional visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis. Methods A total of 8 patients with end-stage hepatic alveolar echinococcosis undergoing liver autotransplantation in Qinghai Provincial People’s Hospital from May 2013 to July 2017 were collected. All cases received preoperative abdominal CT scanning and dynamic three-phase enhanced CT scanning, and the original CT data were transferred to the human 3D visualization virtual surgical planning system. The volumes of Echinococcus multilocularis and pre-resected liver were measured using the 3D visualization reconstruction, and the relationship between the lesion and the neighboring tissues was observed. The value of the 3D visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis was assessed by comparing with the intraoperative findings. Results The 3D visualization reconstruction model clearly displayed the adjacent relationship between the lesions of end-stage hepatic alveolar echinococcosis and the neighboring tissues, and no significant difference was seen between the pre-resected liver volume in 3D visualization reconstruction model and the actually resected liver volume (t = 1.083, P > 0.05). Conclusions 3D visualization technology is feasible to develop a reasonable scheme for liver resection and vascular anastomosis for end-stage hepatic alveolar echinococcosis prior to liver autotransplantation, which may increase the success of surgery and improve the prognosis.
ABSTRACT
Objective To investigate the distribution characteristics of gallbladder diseases in children with hepatic alveolar echinococcosis, and to analyze the related factors for hepatic alveolar echinococcosis and gallbladder diseases. Methods The clinical data of hepatic alveolar echinococcosis patients under 18 years were collected in Qinghai Provincial People’s Hospital-from January 2012 to December 2017, and the gallbladder-related complications in the surgically treated patients with hepatic al-veolar echinococcosis were analyzed. Results The clinical data of 51 child patients with hepatic alveolar echinococcosis were collected and analyzed. According to the PNM classification criteria of WHO, P1, P2 and P3 in the 51 patients accounted for 37.25% (19/51), 41.18% (21/51) and 19.60% (10/51), respectively. According to the diagnostic criteria (WS 257–2006) of China for echinococcosis, the patients of infiltration type, calcification type and liquefaction cavitary type accounted for 66.67% (34/51), 21.57% (11/51) and 11.76% (6/51), respectively. Among the 51 patients, 78.43% (40/51) of the patients had clinical symptoms of biliary tract disease, and 58.82% (30/51) had gallbladder-related complications. The operations were performed on 40 patients, and 77.50% (31/40) of them had the postoperative complications. The results of binary multivariate logistic regression analysis showed that the clinical image classification, the liver segment distribution, size, location and number of lesions of hepatic alveolar echinococcosis were important correlative factors for the occurrence of gallbladder complications in hepatic alveolar echinococcosispatients. Conclusions The incidence of complications related to gallbladder diseases is higher in the children with hepatic alveolar echinococcosis in Qinghai Province, and it has great influence on the operation mode and the occurrence and prognosis of postoperative complications. The early diagnosis and treatment of alveolar echinococcosis in children is particularly important.

ABSTRACT
Objective To assess the value of MRI combined with serum ferritin analysis in measurement of hepatic iron deposition among patients with hepatic alveolar echinococcosis. Methods A total of 96 patients with definitive diagnosis of hepatic alveolar echinococcosis and 30 healthy volunteers were enrolled and underwent routine 1.5T MR scanning, and all laboratory examination data were captured. The liver-to-muscle signal intensity ratio, serum ferritin level and liver functions were analyzed. Results The liver-to-muscle signal intensity ratio was (1.95 ± 0.57) in patients with hepatic alveolar echinococcosis and (2.22 ± 0.28) in healthy volunteers (t = 2.022, P < 0.05), and the liver-to-muscle signal intensity ratio was negatively associated the serum ferritin level in patients with hepatic alveolar echinococcosis (rs = –0.446, P < 0.01). Conclusions Abnormal iron deposition is detected in the liver of patients with hepatic alveolar echinococcosis, and serum ferritin level may be helpful for the identification of abnormal iron deposition in the liver of patients with hepatic alveolar echinococcosis. The liver-to-muscle signal intensity ratio measured by MRI may be a non-invasive approached used to assess the hepatic iron deposition in patients with hepatic alveolar echinococcosis.
ABSTRACT
Objective To investigate the biologic viability and boundary range of hepatic alveolar echinococcosis (HAE) by the contrast-enhanced ultrasonography (CEUS) and acoustic radiation force impulse elastography (ARFI). Methods Totally 27 HAE patients confirmed by pathology underwent CEUS and ARFI examinations. Results Gray scale sonography of HAE showed unclear boundary, inhomogeneous, and middle hyperechoic nodules, and the maximum area was (6.08 ± 4.47) cm2 in 27 lesions. CEUS of HAE showed non-enhancement in three phases and black hole sign. Circumferential enhancement on the pe riphery of the lesion was synchronized with the liver parenchyma and showed “fast in and slow out”. The maximum area was (8.87 ± 4.83) cm2. The area of ECUS was larger than gray scale sonography in HAE (t = 2.20, P = 0.03). The mean shear wave velocities (SWVs) of the interior, the boundary range, and the surrounding liver tissues of HAE were statistically different by ARFI (F = 84.538, P < 0.001), and the interior had the highest values. Conclusions CEUS and ARFI examinations can detect the biologic viability and boundary range of migrating zone around HAE, which is valuable for guiding treatment, judging curative effect, and predicting prognosis.
ABSTRACT
Objective@#To explore the indications and clinical value of orthotropic liver transplantation(OLT)in patients with advanced hepatic alveolar echinococcosis(HAE).@*Methods@#The clinical data of 12 patients with advanced HAE who received OLT from January 2001 to December 2017 were retrospectively analyzed. Among them, there were 7 males and 5 females, the age ranged from 16~58 years(median 42 years). The preoperative hepatic functions of 12 patients were 2 Child-Pugh class A, 3 class B and 7 class C, and the median model for end-stage liver disease(MELD)score was 19.5(8~23).@*Results@#The mean time of OLT procedure and anhepatic phase in 12 patients were 456.25(456.25±44.98)min and 79.17(79.17±10.01)min respectively. The median intraoperative blood loss and hospital stay times were 1000 ml(600~4000 ml), and 29.5(15±58)days respectively. All the patients were followed-up for 0 months to 207 months. Among the 12 patients who underwent OLT, 2 recipients died of incurable infection of pulmonary infection on day 23 post-OLT, and multiple organ failure on day 32 post-OLT, respectively. One case developed lung metastasis 2 years after operation, and brain metastasis was found in the same patient after 4 years. The recurrence occurred 3 years after OLT in another patient, no evidence of HAE recurrence or extrahepatic metastasis was found in the remaining 8 patients.@*Conclusions@#OLT can provide patients with advanced HAE the best chance for long term disease-free and overall survival who lost the opportunity for radical hepatectomy.

ABSTRACT
OBJECTIVE: To explore the clinical application value of perioperative comprehensive management of precise hepatectomy in hepatectomy for hepatic alveolar echinococcosis. METHODS: The clinical data of 62 patients with hepatic alveolar echinococcosis who underwent hemihepatectomy from January 2017 to December 2018 were collected and divided into anatomical hepatectomy group(35 cases)and non-anatomical hepatectomy group(27 cases) according to the method of hepatectomy. The differences of preoperative basic data,intraoperative situation and postoperative clinical indexes between the two groups were compared respectively. RESULTS: There was no significant difference in age,sex,hydatid number,hydatid size and preoperative liver function index between the two groups(P>0.05). However,there were significant differences between the two groups in liver function indexes(ALT,AST,DBIL and TBIL),postoperative complication(medicine) incidence rate and postoperative hospital stay(P<0.05). CONCLUSION: Accurate hepatectomy is also suitable for surgical treatment of patients with hepatic alveolar echinococcosis,and has the advantages of less liver function damage,low incidence of complication(medicine) and short hospitalization time after operation.

ABSTRACT
Hepatic alveolar echinococcosis is a kind of zoonosis with poor prognosis.At present,the diagnosis and treatment are mainly based on ultrasound,CT diagnosis,MRI and other classical imaging by detecting the terminal effects of the changes on the cell molecules of the disease itself,the organ anatomy changes.However,it is found that the above imaging techniques have limitations in the diagnosis and treatment.For example,the infiltration zone of the lesion is not clear and the degree of biological activity can not be determined.This leads to a higher recurrence rate in the late stage of clinical treatment.In recent years,the molecular imaging shows the abnormal cell and molecular level in the disease process has been developed rapidly.This has led to several diagnosis and treatment problems related to liver vesicular disease.This paper mainly reviews the research results of the disease in the field of molecular imaging and the development direction of this field in the future,to provide guidance for future clinical and scientific research.
ABSTRACT
Objective To explore the physiological characteristics of vascular invasion of hepatic alveolar echinococcosis(HAE) and the growth pattern of lesion.Methods 120 cases with HAE were all scanned by 256 slices MSCT,then the images were taken three-dimensional reconstruction.A comparison between pathology and images were made for the evaluation of vascular invasion.Results Pathological examination showed that the invasion rate of intrahepatic vein(left hepatic vein,middle hepatic vein,right hepatic vein, inferior vena cava),portal vein and hepatic artery were 34.38%,31.11%,22.50%,respectively.176 branches of the intrahepatic vein, 67 branches of the hepatic artery and 127 branches of portal vein were involved.Combined with the pathology,the Kappa values were 0.868,0.725 and 0.844.Conclusion HAE is easy to involve the intrahepatic veins as it grows,considering its"indulgence of vein"feature.In order to improve the targeting effect,the mode of administration could be changed.MSCT can exactly evaluate the invasion of intrahepatic vessels,providing important basis for clinical treatment.
