Hepatic alveolar echinococcosis (HAE) is a severe zoonotic disease caused by Echinococcus multilocularis, primarily affecting the liver. Due to its insidious nature, the patients are often diagnosed at advanced stage, posing significant treatment challenges. We comprehensively examines the progress in surgical techniques for HAE management, focusing on various strategies across different disease stages. For the patients with early-stage HAE, ablation therapy has emerged as an effective treatment option. In the moderate to advanced cases, numerous surgical techniques and innovative approaches have been introduced, including laparoscopic surgery and liver transplantation, with particular emphasis on ex vivo liver resection and autotransplantation. These advancements offer more effective treatment options for the patients with advanced HAE. However, significant challenges persist, notably the preservation of adequate liver function while achieving complete lesion removal. Future research should prioritize the exploration and optimization of existing surgical methods, especially for advanced HAE cases. This includes refining surgical techniques through precise preoperative evaluation and staging, as well as developing novel surgical approaches to enhance safety and efficacy. Furthermore, multicenter and long-term follow-up prospective studies are crucial for validating the effectiveness of new surgical techniques and strategies. Through these concerted efforts, it is anticipated that the survival rates and quality of life for HAE patients will significantly be improved, marking a new era in the management of this complex disease.
Objective To study the cl inical characteristics of sacrum echinococcosis disease so as to provide a basis for its diagnosis and treatment. Methods Between July 1999 and August 2010, 14 cases of sacrum echinococcosis disease were treated and the cl inical data were analysed retrospectively. There were 6 males and 8 females with an average age of 28.7 years (range, 16-58 years). The median disease duration was 5.7 years (range, 6 months to 11 years). Twelve cases came from cattle area or had a history of close contact with dogs and sheep; 12 patients had a history of lung or l iver hydatid disease. The main clinical symptoms were lumbosacral and lower extremity pain, one or both lower extremities and perineal hypoesthesia, the gradual dysfunction of both lower extremities and neurogenic bladder and bowel, and decreased force of urination. The imaging examination showed multicystic bone erosion. The Casoni test was performed in 10 cases and the results were positive in 8 cases. The eight immunoserology markers of hydatidosis were detected in 4 cases, and the results were all positive. After entire debridement of the focus, defects were repaired with autogenous bone, allogeneic bone, artificial bone, or bone cement, and then albendazole was used as a routine treatment for 3 months. Results Incisions healed by first intention, and no compl ication occurred. All patients were followed up 6 months to 11 years with a median time of 5.7 years. The preoperative cl inical symptoms were rel ieved. Eight cases recurred at 6 months to 3 years after operation; after debridement (3 times in 5 and 5 times in 1) and the lesions marginal resection with a high-speed burr (2 cases), the symptoms were relieved in different degrees without recurrence. No hydatid disease occurred and spreaded. Conclusion The cl inical manifestation of sacrum is not typical, which is easy to be misdiagnosed. MRI is helpful to diagnosis sacrum echinococcosis disease; serological examination is the major method of identification diagnosis, and surgery is the main treatment method.
ObjectiveTo describe the current situation of the prevalence of hepatic hydatidosis, analyze the clinical characteristics and treatment method of the disease, in order to provide scientific basis for personal treatment plans of hepatic hydatidosis. MethodThe clinical data of 121 patients with recurrent hepatic hydatidosis treated between July 2006 and December 2013 were analyzed retrospectively. The general information of hydatid disease of liver, mass of liver, clinical manifestations, laboratory test results, treatment method, effectiveness of the treatment during hospitalization, and follow-up results were collected and analyzed. ResultsMost of the patients were adults from Sichuan and Tibet, and the majority of them had no clear occupation or clear animal contact history and had not taken raw or fresh meat. Lesions in the right lobe occurred in 87 cases, accounting for 71.90%. Abdominal pain and distension were the main clinical manifestations. Twenty-five (20.66%) of these patients were associated with hepatic dysfunction, among whom 23 patients had mild hepatic dysfunction. Alpha-fetoprotein level was increased in one (0.83%) of these cases. A total of 119 of the 121 patients received surgical treatment (98.35%) and all the surgeries were successful. Follow-up results revealed that three of the patients had recurrence. ConclusionsHepatic hydatidosis is an epidemic mainly in the Tibetan district of the West of China. The disease mainly occurs in the right lobe of the liver, which mainly causes mile liver damage. Hepatocellular carcinoma has not been found in these cases. Surgery treatment is the main therapy for liver hydatidosis and may result in good effectiveness.
The high incidence of hydatid disease in seven northwestern provinces, is one of the reason of "Poverty due to illness, and return poverty due to illness" in China. The incidence of chest hydatid disease in China after hepatic hydatid disease ranks second. Department of thoracic surgery in the First Affiliated Hospital of Xinjiang Medical University is on the domestic leading position of the treatment of chest hydatid disease. Since 1956 the first case of pulmonary hydatid cyst were completed, we have successfully finished the surgical treatment of pediatric chest hydatid disease, chest hydatid disease complex, huge pulmonary hydatid cyst, mediastinal and pleural hydatid cyst, and rib hydatid in our department. To further standardize the treatment of chest hydatid disease, a special formulation of "technical specification for chest hydatid disease diagnosis expert consensus" by our department were produced, in order to help clinicians treat chest hydatid disease by more suitable strategies. This consensus was released in July 2015, for the original version. The definition, diagnosis, treatment principle, and prevention of chest hydatid disease were elaborated and clinical experiences of 60 years were combined with in this consensus, in order to help the clinicians for diagnosis, treatment, and prevention of hydatid disease.
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.
Objective To evaluate effects of three-dimensional (3D) visualized reconstruction technology on short-term benefits of different extent of resection in treating hepatic alveolar echinococcosis (HAE) as well as some disadvantages. Methods One hundred and fifty-two patients with HAE from January 2014 to December 2016 in the Department Liver Surgery, West China Hospital of Sichuan University were collected, there were 80 patients with ≥4 segments and 72 patients with ≤3 segments of liver resection among these patients, which were designed to 3D reconstruction group and non-3D reconstruction group according to the preference of patients. The imaging data, intraoperative and postoperative indicators were recorded and compared. Results The 3D visualized reconstructions were performed in the 79 patients with HAE, the average time of 3D visualized reconstruction was 19 min, of which 13 cases took more than 30 min and the longest reached 150 min. The preoperative predicted liver resection volume of the 79 patients underwent the 3D visualized reconstruction was (583.6±374.7) mL, the volume of intraoperative actual liver resection was (573.8±406.3) mL, the comparison of preoperative and intraoperative data indicated that both agreed reasonably well (P=0.640). Forty-one cases and 38 cases in the 80 patients with ≥4 segments and 72 patients with ≤3 segments of liverresection respectively were selected for the 3D visualized reconstruction. For the patients with ≥4 segments of liver resection, the operative time was shorter (P=0.021) and the blood loss was less (P=0.047) in the 3D reconstruction group as compared with the non-3D reconstruction group, the status of intraoperative blood transfusion had no significant difference between the 3D reconstruction group and the non-3D reconstruction group (P=0.766). For the patients with ≤3 segments of liver resection, the operative time, the blood loss, and the status of intraoperative blood transfusion had no significant differences between the 3D reconstruction group and the non-3D reconstruction group (P>0.05). For the patients with ≥4 segments or ≤3 segments of liver resection, the laboratory examination results within postoperative 3 d, complications within postoperative 90 d, and the postoperative hospitalization time had no significant differences between the 3D reconstruction group and the non-3D reconstruction group (P>0.05). Conclusion 3D visualized reconstruction technology contributes to patients with HAE ≥4 segments of liver resection, it could reduce intraoperative blood loss and shorten operation time, but it displays no remarkable benefits for ≤3 segments of liver resection.
