ObjectiveTo summarize the clinical features of an adult patient with occult cerebral alveolar echinococcosis with liver and lung infection. MethodsA Tibetan male patient in his middle age from the epidemic area of echinococcosis infection was diagnosed to have liver, lung and cerebral alveolar echinococcosis infection in Ganzi People's Hospital. He had the resection surgery, and the pathological result confirmed the primary diagnosis. We searched the literatures from January 1985 to December 2015 for occult cerebral alveolar echinococcosis and reviewed all the full texts in China Journal Full-text Database. Seventeen articles were qualified and 42 patients were reported. Combining with the relevant English literature using Medline, we analyzed the epidemic, pathophysiological and clinical manifestations of cerebral alveolar echinococcosis infection and explored the methods of prevention and treatment. ResultsAccording to the results of literature analysis, cerebral alveolar echinococcosis appeared often secondary to infection of other organs. Nervous system symptom concealed or progressed slowly; imaging and pathological tests were important for diagnosis. Resection surgery was the essential method of cure. ConclusionAlveolar echinococcosis can affect multiple organs. In patients without neurological symptoms, if other organs are found to be infected, it is important to screen patients with intracranial involvement. Because this kind of patients with intracranial lesions with hydatid are often secondary to other organ infection, active treatment in early phase is necessary in order to avoid further expansion of lesions and metastasis.
ObjectiveTo investigate strategies and efficacy of surgical treatment of advanced hepatic alveolar echinococcosis. MethodsThirty-six patients with advanced hepatic alveolar echinococcosis who underwent surgical treatment in our hospital from August 2014 to March 2016 were selected, who were divided into three groups:radical hepatectomy group (15 cases), quasi-radical hepatectomy group (17 cases), and palliative surgery group (4 cases). The operative time, intraoperative blood loss, postoperative complications, and metastasis were analyzed among these three groups. ResultsThe operative time, intraoperative blood loss, and rate of postoperative complications had no significant differences between the radical hepatectomy group and the quasi-radical hepatectomy group. No patient had postoperative recurrence in the radical hepatectomy group. The hepatic portal residual lesion was enlarged for 1 case and the intrahepatic and extrahepatic lesions were stable for the other patients in the quasi-radical hepatectomy group. In the palliative surgery group,the retroperitoneal lesions enlargement was seen in 2 cases and the lesions around the abcess grew progressively in 1 case. ConclusionIndividualized treatment accompanied with multiple-disciplinary treatment and damage-control surgery concept could benefit optimally to patients with advanced hepatic alveolar echinococcosis.
Echinococcosis is a zoonotic disease that seriously threatened human health. The disease is widely distributed in China, including in Tibet Autonomous Region, Qinghai Province, Xinjiang Uygur Autonomous Region, Sichuan Province, and other places, which has become a social and economic burden in China. Human beings are mainly infected with alveolar echinococcosis (AE) and cystic echinococcosis (CE), which mainly involves liver, lung, brain, bone, and other organs or tissues. The surgical resection is the first line treatment, and antiparasitic agents therapy is the main supplementary or salvage treatment method. Currently, classic drugs mainly include albendazole and praziquantel, which use alone or in combination. There are also some attempts to treat echinococcosis, including broad-spectrum anti infective drugs such as nitrozotocin, cell proliferation inhibiting drugs such as bortezomib, metabolic drugs such as metformin, or traditional medicines such as Artemisinin. It was also suggested to adopt a cancer management model for echinococcosis, and the imaging follow-up time for CE after antiparasitic chemotherapy should be at least 3 years, and for AE should be at least 10 years. More importantly, measures such as education and vaccine inoculation should be taken to actively prevent and control the occurrence and spread of echinococcosis.
ObjectivesTo evaluate the learning curve of radical hepatectomy combined with vascular and/or bile duct reconstruction (RHVBR) in the treatment of hepatic alveolar echinococcosis (HAE), and to explore the feasibility and safety of RHVBR. MethodsThe clinical data of 203 patients who received RHVBR treatment for HAE complicated with vascular invasion in West China Hospital from 2010 to 2018 were analyzed retrospectively. Cumulative sum (CUSUM) and risk-adjusted cumulative sum (RA-CUSUM) were used to analyze the learning curve of RHVBR, determine the learning stage, and compare the differences of intraoperative and postoperative outcome indexes in different learning stages. ResultsThe average operative time was (537.9±207.6) minutes, with blood loss amounted to 617.3 (138.9, 1 094.2) mL. Postoperative complications occurred in 65 cases, and the incidence of complications was 32.0%. Among them, 29 cases (14.3%) had serious complications. Three cases (1.5%) died within 90 days after operation. The results of RA-CUSUM analysis showed that 54 cases of surgery were the cut-off point of learning curve for serious postoperative complications. According to the results of CUSUM analysis, the whole queue was divided into the first stage (n=53) and the second stage (n=150) based on the completion of 53 operations. Compared with the first stage, the operative time and total postoperative hospital stay in the second stage was shortened, the incidence of serious complications was reduced, and the number of resected liver segments was increased. The differences were statistically significant (P<0.05). ConclusionIt is feasible and safe to treat HAE with RHVBR, and the incidence of serious complications is obviously reduced after 54 cases of operation.
ObjectiveTo summarize the therapeutic effect and clinical significance of reduced volume lesion resection combined with drug therapy for end-stage alveolar hepatic echinococcosis.MethodClinical data of 46 patients with end-stage alveolar hepatic echinococcosis who received treatment of reduced volume lesion resection combined with drug therapy at Department of General Surgery of Qinghai Provincial People’s Hospital from March 2013 to October 2019 were retrospectively analyzed.ResultsAmong the 46 patients, 3 patients were lost to follow-up and 43 patients received follow-up. The follow-up time ranged from 3 to 79 months, with the median of 40 months. Fifteen patients died during the follow-up period, of which 5 patients with cerebral hydatid disease died during 16–36 months due to acute seizures and cerebral edema, 4 patients with multiple systemic metastases died during 9–36 months due to multiple organ failure, 2 patients with pulmonary echinococcosis died due to acute pulmonary embolism, 4 patients died in 2 years after operation due to recurrent biliary tract infection, other patients survived during follow-up period without distant organ metastasis.ConclusionReduced volume lesion resection combined with drug therapy in treatment of end-stage alveolar hepatic echinococcosis can improve the patient’s quality of life, reduce the hospital cost, reduce the occurrence of postoperative complications, and shorten the length of hospital stay.
ObjectiveTo summarize short-term and long-term effects of ex vivo liver resection followed by autotransplantation (Abbreviation: autotransplantation) in treatment of advanced hepatic alveolar echinococcosis (HAE).MethodThe clinical data and follow-up data of 17 patients with advanced HAE who underwent autotransplantation from November 2016 to July 2019 in the Ganzi Tibetan Autonomous Prefecture People’s Hospital were retrospectively analyzed.ResultsThe autotransplantations were performed successfully in the 17 patients with advanced HAE. Ten patients underwent the inferior vena cava (IVC) reconstruction with autologous saphenous veins, 5 patients underwent the artificial revascularization, 1 patient underwent the direct anastomosis of the original IVC, and 1 patient didn’t reconstructed (the retroperitoneal collateral circulation was abundant). The mean liver graft mass was 681.3 g (365–1 350 g) and operation time was 11.5 h (9–16 h). The median anhepatic period was 312 min (175–450 min), blood loss was 2 000 mL(950–4 500 mL), red blood cell suspension transfusion was 6.4 U (1–20 U), and fresh frozen plasma was 1.1 L (0.8–2.0 L). The postoperative hospital stay was 5 to 45 d with an average of 25.6 d. There were 4 patients with the postoperative hepatic enveloping effusion, 1 patient with bile leakage, and 1 patient with bile duct stenosis. All of them were treated and cured, and no death occurred. The follow-up time of 17 patients was 3 to 35 months with an average of 9.5 months, no recurrence of HAE and distant metastasis were observed.ConclusionsIn highlands, autotransplantation in treatment of advanced HAE patients with different IVC reconstruction is satisfactory, but it has a higher risk and is difficult. Choice of intraoperative reconstruction materials, judgment of posterior peritoneal collateral circulation, presence or absence of tension in end-to-end anastomosis of the IVC require precise consideration. At the same time, anticoagulation therapy and complications management are difficult, and it is only suitable for plateau medical center with rich experience.
ObjectiveTo understand the current situation in the treatment of hepatic echinococcosis. MethodThe literatures about operation treatment, drug treatment, and the clinical pathway of hepatic echinococcosis were reviewed. ResultsCurrently, with the continuous development of surgical techniques and the application of minimally invasive surgery, the operative treatments of hepatic echinococcosis had made a great progress, it was still the preferred treatment for the disease. Liver transplantation was made as the final choice. The use of aspiration, sclerotherapy or interventional technique brought a hope for patients intolerant to laparotomy. Moreover, chemotherapy drugs, Chinese herbal medicine, and drug combinations also achieved a very good effect in the treatment of hepatic echinococcosis. The clinical pathway provided a good direction for the treatment of hepatic echinococcosis. ConclusionFor the treatment of hepatic echinococcosis various, we should choice a reasonable treatment according to the specific circumstances of patients, to achieve the best therapeutic effect with minimal trauma.
ObjectiveTo evaluate roles and advantages of magnetic resonance imaging (MRI) and compute.tomography (CT) in preoperative assessment for hepatic alveolar echinococcosis. MethodMRI and CT scan imaging data of 60 patients with hepatic alveolar echinococcosis underwent radical surgery were retrospectively analyzed. ResultsMRI scanning could accurately identify the peripheral zone and marginal zone of hepatic alveolar echinococcosis lesions, and CT could not accurately show the above structures. In assessment of anatomic relation between vascular and lesions, MRI findings of 52 cases were in full compliance with corresponding intraoperative findings, and 8 cases were partial compliant. However, CT findings of 35 cases were in full compliance with corresponding intraoperative findings, 13 cases were partial compliant, and 12 cases were not compliant at all. In assessment of anatomic relation between biliary and lesions, MRCP could clearly show the bile duct, bile duct stenosis location and degree; CT scanning could only show widened bile duct, but could not accurately judge bile duct dilatation. ConclusionsMRI exerts some obvious advantages in preoperative evaluation of hepatic alveolar echinococcosis, and could accurately find relation between lesions and vascular or biliary system. MRI should be used as routine examination for patients with hepatic alveolar echinococcosis.
ObjectiveTo explore potential value of three-dimensional reconstruction technique for preoperative evaluation of hepatic alveolar echinococcosis. MethodsTwenty-one cases of hepatic alveolar echinococcosis proved by postoperative pathological examination in Affiliated Hospital of Qinghai University from October 2013 to March 2014 were analyzed retrospectively. The three periods of patients’ liver dynamic thin layerCTscan images were collected and imported in three-dimensional reconstruction software by DICOM format. The volume of the virtual resected liver tissue was calculated by software, and then was compared with the actual resected liver tissue volume. ResultsThe resected liver volume was (761.94±505.77) mL and (756.19±501.78) mL in the virtual surgery and in the veritable surgery, respectively. The proportion of resected liver in the total liver was (39.27±18.75)% and (38.95±16.99)% in the virtual surgery and in the veritable surgery, respectively. The resected liver volume had no significant difference between the virtual surgery and veritable surgery (P>0.05), which a positive relation (r=0.989, P<0.001). ConclusionThe limited preliminary data in this study show that three-dimensional reconstruction technique and virtual planning system for surgery could accurately guide resection of lesion and provide preoperative guidance of accurate liver resection for hepatic alveolar echinococcosis.
ObjectiveTo evaluate and discuss the various surgical methods for hepatic echinococcosis. MethodsFour hundred and two patients with hepatic echinococcosis were treated in West China Hospital of Sichuan University from 2009 to 2014 and 271 of them were undergone surgical treatment. The cystic echinococcosis was in 195 patients, including 80 cases performed classic endocystectomy or subtotal cystectomy, 109 performed total cystectomy or hepatectomy, 6 cases performed palliative surgery. The alveolar echinococcosis was in 76 patients, including 7 cases performed palliative surgery, 54 cases performed hepatectomy, 12 cases performed liver allotransplantation, and 3 cases performed liver autotransplantation. Results①The draining time, the rate of postoperative complications, and the recurrence was (18.6±2.7) d, 21.2% (17/80), and 15.0%(12/80) respectively in the cases of cystic echinococcosis underwent classic endocystectomy or subtotal cystectomy, which were significantly higher than those cases of cystic echinococcosis underwent total cystectomy or hepatectomy〔(5.4±0.6) d, 7.3% (8/109), and 0.9% (1/109), respectively, P < 0.05〕.②The draining time and the recurrence was (5.9±0.7) d and 1.8% (1/54) respectively in the cases of alveolar echinococcosis underwent hepatectomy, which were significantly lower than those in the cases of alveolar echinococcosis took palliative surgery〔(9.7±1.4) d and 57.1% (4/7), respectively, P < 0.01〕. The 12 patients underwent liver transplantation were complete rehabilitation, while the rest 3 were death. Conclusions①Total cystectomy or hepatectomy should be the first choice for cystic echinococcosis; Palliative treatment could improve the symptoms of unresectable patients with cystic echinococcosis.②Hepatectomy should be the first choice for alveolar echinococcosis, palliative surgery could only be used to alleviate symptoms and physical signs, delay the progression of this disease.③Liver transplantation might be an alternative for advanced hepatic echinococcosis.
