RESUMEN
Introduction: Total cystectomy and hepatectomy are the main radical surgical procedures for hepatic cystic echinococcosis (CE). When CE lesions severely invade intrahepatic biliary ducts and vessels or single or multiple lesions occupy one hepatic lobe, performing total cystectomy is not indicated. This study aimed to analyze the clinical efficiency of anatomical hepatectomy in the treatment of patients with hepatic CE. Methods: Clinical data of 74 patients with hepatic CE who received anatomical hepatectomy were retrospectively analyzed from January 2005 to January 2022. The patients were classified into the intrahepatic biliary duct invasion group (group A), the intrahepatic vessel invasion group (group B), and the hepatic lobe occupation group (group C). Results: Among these 74 patients who received anatomical hepatectomy, right hepatectomy was performed in 20 cases (27.03%), left hepatectomy in 26 cases (35.13%), right posterior lobectomy in nine cases (12.16%), and left lateral sectionectomy in 19 cases (25.68%). Short-term post-operative complications occurred in seven cases (9.50%), including abdominal abscess in one case, pleural effusion in three cases, intestinal obstruction in one case, incision infection in one case, and ascites in one case. Long-term post-operative complications occurred in four cases (5.4%), including recurrences of CE in two cases and incisional hernias in another two cases. There were no statistical differences in the concentrations of total bilirubin, alanine aminotransferase, and aspartic transaminase before and after surgery between groups (p > 0.05). However, differences in operative time, short-term post-operative complications, average hospital stay, and number of open hepatectomy cases were statistically significant between groups (p < 0.05). The differences in cases receiving hepatic portal occlusion, intra-operative blood loss, and intra-operative blood transfusion were not statistically significant between groups (p > 0.05). Conclusions: Anatomical hepatectomy is an effective and feasible surgical procedure for patients with hepatic CE with severe invasion of intrahepatic biliary ducts and vessels or patients with huge lesions occupying one hepatic lobe, which effectively avoids residual cavity-related complications.
RESUMEN
Intrahepatic cholangiocarcinoma (iCCA) is a prevalent liver tumor that presents a diagnostic challenge due to its nonspecific symptoms, necessitating reliance on imaging techniques for accurate diagnosis. The similarity of imaging features with other liver diseases, such as hepatocellular carcinoma (HCC) and hepatic alveolar echinococcosis, often leads to confusion and misdiagnosis. In contrast, the distinct characteristics of hepatic cystic echinococcosis (HCE) result in fewer reported misdiagnoses. A case involving a 53-year-old female from Changji (Xinjiang, China) diagnosed with iCCA, who was hospitalized for symptoms of upper abdominal distension and pain, along with nausea and vomiting, is presented. The patient underwent a partial hepatectomy in 1990 for hepatic echinococcosis. Abdominal computed tomography revealed multiple, quasicircular, low-density masses in the hilar region and right anterior lobe of the liver, with the largest measuring 5.61 cm × 4.84 cm. Enhanced computed tomography did not reveal significant enhancement of the lesion. Considering epidemiological factors, medical history, and imaging findings, the initial diagnosis was HCE, which prompted surgical intervention. The diagnosis of iCCA with necrosis was confirmed via pathological examination. The literature and relevant sources were consulted to establish that biliary tract tumors with necrosis or mucin production typically do not exhibit significant enhancement in enhanced scans, maintaining a consistently low density across all phases, resembling the presentation of HCE. When making diagnoses based on imaging data, it is essential to have knowledge of both the typical features and unique manifestations of the disease. In specific instances, relying solely on epidemiology and medical history may lead to incorrect conclusions. Therefore, comprehensive consideration of all aspects is necessary to prevent missed diagnoses and misdiagnoses.
RESUMEN
BACKGROUND: Lymph node metastasis is a specific type of metastasis in hepatic alveolar echinococcosis (AE). Currently, there is a scarcity of describing the clinical characteristics and lymph node metastasis rules of patients with hepatic AE combined with lymph node metastasis and its mechanism and management are still controversial. Radical hepatectomy combined with regional lymph node dissection is a better treatment. AIM: To analyse the clinical features of hepatic AE combined with lymph node metastasis to explore its treatment and efficacy. METHODS: A total of 623 patients with hepatic AE admitted to the First Affiliated Hospital of Xinjiang Medical University from 1 January 2012 to 1 January 2022 were retrospectively analysed. Fifty-five patients with combined lymph node metastasis were analysed for their clinical data, diagnosis and treatment methods, follow-up efficacy, and characteristics of lymph node metastasis. Finally, we comparatively analysed the lymph node metastasis rates at different sites. Categorical variables are expressed as frequencies and percentages, and the analysis of difference was performed using the χ 2 test. The Bonferroni method was used for pairwise comparisons when statistical differences existed between multiple categorical variables. RESULTS: A lymph node metastasis rate of 8.8% (55/623) was reported in patients with hepatic AE, with a female predilection (69.1%) and a statistically significant sex difference (χ 2 = 8.018, P = 0.005). Of the 55 patients with lymph node metastasis, 72.7% had a parasite lesion, neighbouring organ invasion, and metastasis stage of P3N1M0 and above, of which 67.3%, 78.2%, and 34.5% of hepatic AE lesions invaded the bile ducts, blood vessels, and distant metastases, respectively. Detection rates of lymph node metastasis of 16.4%, 21.7%, and 34.2% were reported for a preoperative abdominal ultrasound, magnetic resonance imaging, and computed tomography examinations. All patients were intraoperatively suspected with enlarged lymph nodes and underwent radical hepatectomy combined with regional lymph node dissection. After surgery, a routine pathological examination was conducted on the resected lymph nodes. A total of 106 positive lymph nodes were detected in six groups at various sites, including 51 single-group metastasis cases and four multi-group metastasis cases. When the metastasis rates at different sites were statistically analysed, we observed that the metastasis rate in the para-hepatoduodenal ligament lymph nodes was significantly higher than that of the other sites (χ 2 = 128.089, P = 0.000 < 0.05). No statistical difference was observed in the metastasis rate between the five other groups. Clavien-Dindo grade IIIa complication occurred in 14 cases, which improved after administering symptomatic treatment. Additionally, lymph node dissection-related complications were not observed. Recurrence after 2 years was observed in one patient. CONCLUSION: Lymph node metastasis is a rare form of metastasis in hepatic AE, which is more frequent in women. Para-hepatoduodenal ligament lymph nodes are commonly observed. Radical hepatectomy combined with regional lymph node dissection is a safe, effective, and feasible treatment for liver AE combined with lymph node metastasis.

BACKGROUND: Alveolar 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 PRESENTATION: We 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. CONCLUSIONS: The 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.

Immune exhaustion corresponds to a loss of effector function of T cells that associates with cancer or chronic infection. Here, our objective was to decipher the mechanisms involved in the immune suppression of myeloid-derived suppressor cells (MDSCs) and to explore the potential to target these cells for immunotherapy to enhance checkpoint blockade efficacy in a chronic parasite infection. We demonstrated that programmed cell-death-1 (PD-1) expression was significantly upregulated and associated with T-cell dysfunction in advanced alveolar echinococcosis (AE) patients and in Echinococcus multilocularis-infected mice. PD-1 blockade ex vivo failed to reverse AE patients' peripheral blood T-cell dysfunction. PD-1/PD-L1 blockade or PD-1 deficiency had no significant effects on metacestode in mouse model. This was due to the inhibitory capacities of immunosuppressive granulocytic MDSCs (G-MDSCs), especially in the liver surrounding the parasite pseudotumor. MDSCs suppressed T-cell function in vitro in an indoleamine 2, 3 dioxygenase 1 (IDO1)-dependent manner. Although depleting MDSCs alone restored T-cell effector functions and led to some limitation of disease progression in E. multilocularis-infected mice, combination with PD-1 blockade was better to induce antiparasitic efficacy. Our findings provide preclinical evidence in support of targeting MDSC or combining such an approach with checkpoint blockade in patients with advanced AE. (200 words).

BACKGROUND: Posthepatectomy liver failure remains a potentially life-threatening complication after hepatectomy. Soluble suppression of tumourigenicity 2 is an injury-related biomarker. The aim of the study was to assess soluble suppression of tumourigenicity 2 elevation after hepatectomy and whether it can predict posthepatectomy liver failure. METHODS: This was a single-centre retrospective study including all patients who underwent a liver resection between 2015 and 2019. Plasma concentrations of soluble suppression of tumourigenicity 2 were measured before surgery and at postoperative days 1, 2, 5 and 7. Posthepatectomy liver failure was defined according to the International Study Group of Liver Surgery and the morbidity rate was graded according to the Clavien-Dindo classification. RESULTS: A total of 173 patients were included (75 underwent major and 98 minor resection); plasma levels of soluble suppression of tumourigenicity 2 increased from 43.42 (range 18.69-119.96) pg/ml to 2622.23 (range 1354.18-4178.27) pg/ml on postoperative day 1 (P < 0.001). Postoperative day 1 soluble suppression of tumourigenicity 2 concentration accurately predicted posthepatectomy liver failure ≥ grade B (area under curve = 0.916, P < 0.001) and its outstanding performance was not affected by underlying disease, liver pathological status and extent of resection. The cut-off value, sensitivity, specificity, positive predictive value and negative predictive value of postoperative day 1 soluble suppression of tumourigenicity 2 in predicting posthepatectomy liver failure ≥ grade B were 3700, 92%, 85%, 64% and 97% respectively. Soluble suppression of tumourigenicity 2high patients more frequently experienced posthepatectomy liver failure ≥ grade B (64.3% (n = 36) versus 2.6% (n = 3)) and Clavien-Dindo IIIa higher morbidity rate (23.2% (n = 13) versus 5.1% (n = 6)) compared with soluble suppression of tumourigenicity 2low patients. CONCLUSIONS: Soluble suppression of tumourigenicity 2 may be a reliable predictor of posthepatectomy liver failure ≥ grade B as early as postoperative day 1 for patients undergoing liver resection. Its role in controlling hepatic injury/regeneration needs further investigation. Registration number: ChiCTR-OOC-15007210 (www.chictr.org.cn/).

BACKGROUND: The purpose of this study was to explore the relevant risk factors associated with biliary complications (BCs) in patients with end-stage hepatic alveolar echinococcosis (HAE) following ex vivo liver resection and autotransplantation (ELRA) and to establish and visualize a nomogram model. METHODS: This study retrospectively analysed patients with end-stage HAE who received ELRA treatment at the First Affiliated Hospital of Xinjiang Medical University between August 1, 2010 and May 10, 2023. The least absolute shrinkage and selection operator (LASSO) regression model was applied to optimize the feature variables for predicting the incidence of BCs following ELRA. Multivariate logistic regression analysis was used to develop a prognostic model by incorporating the selected feature variables from the LASSO regression model. The predictive ability, discrimination, consistency with the actual risk, and clinical utility of the candidate prediction model were evaluated using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA). Internal validation was performed by the bootstrapping method. RESULTS: The candidate prediction nomogram included predictors such as age, hepatic bile duct dilation, portal hypertension, and regular resection based on hepatic segments. The model demonstrated good discrimination ability and a satisfactory calibration curve, with an area under the ROC curve (AUC) of 0.818 (95% CI 0.7417-0.8958). According to DCA, this prediction model can predict the risk of BCs occurrence within a probability threshold range of 9% to 85% to achieve clinical net benefit. CONCLUSIONS: A prognostic nomogram with good discriminative ability and high accuracy was developed and validated to predict BCs after ELRA in patients with end-stage HAE.

The sympathetic nervous system (SNS) affects many functions of the body. SNS fibers regulate many aspects of liver function, repair, and regeneration. However, in the model of bile duct ligation (BDL) in rats, the kind of impact caused by the regulation of liver SNS on liver fibrosis and liver regeneration is unclear. The main research objective of this experiment is to examine the effect of SNS on liver fibrosis and liver regeneration. Twenty-four male Sprague-Dawley (SD) rats were assigned randomly to four groups. These groups included the sham surgery group (sham), model group (BDL), 6-hydroxydopamine group (BDL+6-OHDA), and spinal cord injury group (BDL+SCI). In the sham group, only exploratory laparotomy was performed without BDL. In the 6-OHDA group, 6-OHDA was used to remove sympathetic nerves after BDL. In the spinal cord injury group, rats underwent simultaneous BDL and spinal cord injury. After 3 weeks of feeding, four groups of rats were euthanized using high-dose anesthesia without pain. Moreover, liver tissue and blood were taken to detect liver fibrosis and regeneration indicators. After intraperitoneal injection of 6-OHDA into BDL rats, liver fibrosis indicators decreased. The administration of the injection effectively alleviated liver fibrosis and inhibited liver regeneration. However, after SCI surgery in BDL rats, liver fibrosis indicators increased. This resulted in exacerbating liver fibrosis and activating liver regeneration. The SNS plays a role in contributing to the liver injury process in the rat BDL model. Therefore, regulating the SNS may become a novel method for liver injury treatment.

BACKGROUND Alveolar echinococcosis, a lethal parasitic disease, can invade important vessels in the liver. A liver vascular anomaly causes compensatory changes in other blood vessels connected to it because of the close relationship between them. Obstruction of the retrohepatic inferior vena cava and the second hilum can form the intrahepatic venous network and the vertebral venous plexus pathway, which can be demonstrated by hepatic venography and anatomical and autopsy studies. CASE REPORT A Tibetan woman, age 31, with hepatic alveolar echinococcosis and unique intrahepatic hemodynamic features, was referred to our center and underwent successful ex vivo liver resection and autotransplantation. We report our experience and review the literature. In this clinical case, we performed an ex vivo liver resection and autotransplantation without hepatic inferior vena cava reconstruction. After surgery, the circulatory system hemodynamic remained stable, and blood flow in the liver and trunk was unhindered. The patient underwent an uneventful hospitalization and recovery. CONCLUSIONS This clinical case demonstrates the unique venous access, hemodynamic alterations, and surgical decision-making that follow the invasion of significant hepatic vessels by alveolar echinococcosis lesions. HAE exhibits unique collateral vessels, which are uncommon in other diseases. Additionally, this kind of therapy offers fresh perspectives for the surgical treatment of end-stage HAE.

BACKGROUND: Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients' recovery. METHODS: This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group (n = 665) and fasting group (n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. RESULTS: The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t = 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26-0.71, P <0.001) and 0.76 (95% CI: 0.57-0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05-0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39-0.95, P = 0.028) in the multivariable models. CONCLUSION: Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery. TRAIL REGISTRATION: ClinicalTrials.gov, No. NCT03075280.
RESUMEN
BACKGROUND: Ex vivo liver resection and autotransplantation (ELRA) is an essential approach for treating patients with end-stage hepatic alveolar echinococcosis (AE), and its surgical indications involve severe invasion of important hepatic vessels, which makes in vivo resection impossible. Revascularization is a major step in the process of ELRA, which is extremely challenging when the invaded vessels have huge defects. CASE SUMMARY: Herein, we have reported the case of a 26-year-old patient with hepatic AE in an autologous liver graft who underwent complex inferior vena cava (IVC) reconstruction using disease-free IVC, autologous portal vein fragments, and umbilical vein within the ligamentum teres hepatis. The patient showed good surgical recovery without vascular-related complications during the long-term follow-up. CONCLUSION: We reviewed three studies that have reported complex revascularization of the IVC. This case report and systematic review showed that the use of autologous perihepatic vessels prevents donor-area trauma, immune rejection, and other adverse reactions. When the blood vessel is severely invaded and a single vascular material cannot repair and reconstruct the defect, ELRA may provide a safe and feasible surgical approach, which has good prospects for clinical application.
RESUMEN
Objective: To investigate the current status of surgical nurses' implementation of enhanced recovery after surgery (ERAS) concepts in the context of precision nursing in Xinjiang and to provide a basis for the development of precision nursing of ERAS. Methods: By way of convenience sampling, surgical nurses from 8 tertiary-care hospitals were involved in a survey on their ERAS implementation status in March and April 2023 and the results were collected by online questionnaire. Results: A total of 985 valid questionnaires were collected. Out of the 8 hospitals covered in the survey, the orthopedics departments of 7 hospitals have implemented ERAS concepts, accounting for 87.50%. The average score for the ERAS Knowledge, Attitude, and Practice Questionnaire among the surgical nurses was (182.98±17.69), of which, the average score for ERAS knowledge was (13.08±1.51), the average score for ERAS attitude was (88.75±8.30), and the average score for ERAS practice was (81.15±11.96). A total of 61.02% of the surgical nurses implemented ERAS pathways that concentrated on 4-6 pathways, with the prevention of postoperative ileus after surgery being the most commonly implemented pathway, accounting for 498 (50.56%) surgical nurses. A total of 78.48% of the nurses considered work overload to be the most important obstacle to implementing ERAS in the context of precision nursing. Poor multidisciplinary team collaboration and poor awareness of implementation among the nurses ranked the second and the third, accounting for 74.92% and 71.57%, respectively, of the surgical nurses. Conclusion: ERAS has won the approval of surgical nurses in Xinjiang, but it is still not widely implemented in all surgical fields. In addition, the quantity and quality of ERAS pathways implemented still need to be further improved. The development of ERAS in the context of precision nursing remains a long-term challenge.

Background: Hepatic cystic echinococcosis (HCE) rupture into the biliary tract, one of the most common and refractory complications, is treated by laparotomy to remove hydatid lesions. The aim of this article was to investigate the role of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of this particular disease. Patients and Methods: This was is a retrospective analysis of 40 patients with HCE ruptured into the biliary tract in our hospital from September 2014 to October 2019. They were divided into two groups, ERCP group (group A, n = 14) and conventional surgery group (group B, n = 26). Group A was treated with ERCP first to control infection and improve the general condition before undergoing laparotomy at an optional stage while group B was treated with laparotomy directly. First, the infection parameters and liver, kidney and coagulation functions of group A patients before and after ERCP were compared to evaluate treatment effectiveness. Second, the intraoperative and post-operative parameters during the laparotomy of group A were compared with group B to evaluate the impact of ERCP treatment on laparotomy. Results and Conclusions: White blood cell, NE%, platelet, procalcitonin, C-reactive protein, interleukin-6, Total bilirubin (TBIL), alkaline phosphatase, gamma-glutamyl transpeptidase, aspartate transaminase, alanine transaminase (ALT), ALT and Cr in group A significantly improved by ERCP (P < 0.05); during laparotomy, the bleeding amount and hospital stay in group A were better (P < 0.05); moreover, concerning the post-operative complications, the incidence of acute renal failure and coagulation dysfunction in group A was significantly less (P < 0.05). ERCP, which not only quickly and effectively controls infection and improves the patient's systemic condition but also provides good support for subsequent radical surgery, enjoys good prospects for clinical application.
RESUMEN
BACKGROUND: Hepatic alveolar echinococcosis (HAE), as a benign parasitic disease with malignant infiltrative activity, grows slowly in the liver, allowing sufficient time for collateral vessels to emerge in the process of vascular occlusion. METHODS: The portal vein (PV), hepatic vein and hepatic artery were observed by enhanced CT and the inferior vena cava (IVC) by angiography, respectively. Analysis of the anatomical characteristics of the collateral vessels helped to look into the pattern and characteristics of vascular collateralization caused by this specific etiology. RESULTS: 33, 5, 12 and 1 patients were included in the formation of collateral vessels in PV, hepatic vein, IVC and hepatic artery, respectively. PV collateral vessels were divided into two categories according to different pathways: type I: portal -portal venous pathway (13 cases) and type II: type I incorporates a portal-systemic circulation pathway (20 cases). Hepatic vein (HV) collateral vessels fell into short hepatic veins. The patients with IVC collateral presented with both vertebral and lumbar venous varices. Hepatic artery collateral vessels emanating from the celiac trunk maintains blood supply to the healthy side of the liver. CONCLUSIONS: Due to its special biological nature, HAE exhibited unique collateral vessels that were rarely seen in other diseases. An in-depth study would be of great help to improve our understanding related to the process of collateral vessel formation due to intrahepatic lesions and its comorbidity, in addition to providing new ideas for the surgical treatment of end-stage HAE.

BACKGROUND: This study was designed to investigate clinical efficiency and application indications of hepatic lobe hyperplasia techniques for advanced hepatic alveolar echinococcosis (AE) patients. METHODS: A retrospective case series covering 19 advanced hepatic AE patients admitted to the First Affiliated Hospital of Xinjiang Medical University from September 2014 to December 2021 and undergoing hepatic lobe hyperplasia techniques due to insufficient remnant liver volume were analyzed. Changes of liver function, lesions volume, remnant liver volume, total liver volume before and after operation have been observed. RESULTS: Among the patients, 15 underwent portal vein embolization (PVE). There was no statistical difference in total liver volume and lesions volume before and after PVE (P > 0.05). However, the remnant liver volume was significantly increased after PVE (P < 0.05). The median monthly increase rate in future liver remnant volume (FLRV) after PVE stood at 4.49% (IQR 3.55-7.06). Among the four patients undergoing two-stage hepatectomy (TSH), FLRV was larger than that before the first stage surgery, and the median monthly increase rate in FLRV after it stood at 3.34% (IQR 2.17-4.61). Despite no statistical difference in total bilirubin (TBil), albumin (Alb), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT) in all patients with PVE, four patients who underwent TSH showed a decrease in ALT, AST and GGT. During the waiting process before the second stage operation, no serious complications occurred in all patients. CONCLUSIONS: For patients suffering from advanced hepatic AE with insufficient FLRV, PVE and TSH are safe and feasible in promoting hepatic lobe hyperplasia.

Human alveolar echinococcosis (AE) is a tumor-like disease predominantly located in the liver. The cellular composition and heterogeneity of the lesion-infiltrating lymphocytes which produce an "immunosuppressive" microenvironment are poorly understood. Here, we profiled 83,921 CD45+ lymphocytes isolated from the peripheral blood (PB), perilesion (PL), and adjacent normal (AN) liver tissue of four advanced-stage AE patients using single-cell RNA and T-cell receptor (TCR) sequencing technology. We identified 23 large clusters, and the distributions and transcriptomes of these cell clusters in the liver and periphery were different. The cellular proportions of exhausted CD8+ T cells and group 2 innate lymphoid cells (ILC2s) were notably higher in PL tissue, and the expression features of these cell subsets were related to neoplasm metastasis and immune response suppression. In the 5 CD8+ T-cell populations, only CD8+ mucosa-associated invariant T (MAIT) cells were enriched in PL samples and the TRAV1-2_TRAJ33_TRAC TCR was clonally expanded. In the 11 subsets of CD4+ T cells, Th17 cells and induced regulatory T cells (iTregs) were preferentially enriched in PL samples, and their highly expressed genes were related to cell invasion, tumor metastasis, and inhibition of the inflammatory immune response. Exhaustion-specific genes (TIGIT, PD-1, and CTLA4) were upregulated in Tregs. Interestingly, there was a close contact between CD8+ T cells and iTregs or Th17 cells, especially for genes related to immunosuppression, such as PDCD1-FAM3C, which were highly expressed in PL tissue. This transcriptional data set provides valuable insights and a rich resource for deeply understanding the immune microenvironment in AE, which could provide potential target signatures for AE diagnosis and immunotherapies.
