Abstract
Focal liver lesions (FLLs) have become an increasingly common finding on abdominal imaging, especially asymptomatic and incidental liver lesions. Gastroenterologists and hepatologists often see these patients in consultation and make recommendations for management of multiple types of liver lesions, including hepatocellular adenoma, focal nodular hyperplasia, hemangioma, and hepatic cystic lesions including polycystic liver disease. Malignancy is important to consider in the differential diagnosis of FLLs, and healthcare providers must be familiar with the diagnosis and management of FLLs. This American College of Gastroenterology practice guideline uses the best evidence available to make diagnosis and management recommendations for the most common FLLs.

Abstract
Notably, the number of incidentally detected focal liver lesions (FLLs) has increased dramatically in recent years due to the increased use of radiological imaging. The diagnosis of FLLs can be made through a well-documented medical history, physical examination, laboratory tests, and appropriate imaging methods. Although benign FLLs are more common than malignant ones in adults, even in patients with primary malignancy, accurate diagnosis of incidental FLLs is of utmost clinical significance. In clinical practice, FLLs are frequently evaluated non-invasively using ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Although US is a cost-effective and widely used imaging method, its diagnostic specificity and sensitivity for FLL characterization are limited. FLLs are primarily characterized by obtaining enhancement patterns through dynamic contrast-enhanced CT and MRI. MRI is a problem-solving method with high specificity and sensitivity, commonly used for the evaluation of FLLs that cannot be characterized by US or CT. Recent technical advancements in MRI, along with the use of hepatobiliary-specific MRI contrast agents, have significantly improved the success of FLL characterization and reduced unnecessary biopsies. The American College of Radiology (ACR) appropriateness criteria are evidence-based recommendations intended to assist clinicians in selecting the optimal imaging or treatment option for their patients. ACR Appropriateness Criteria Liver Lesion-Initial Characterization guideline provides recommendations for the imaging methods that should be used for the characterization of incidentally detected FLLs in various clinical scenarios. The American College of Gastroenterology (ACG) Clinical Guideline offers evidence-based recommendations for both the diagnosis and management of FLL. American Association for the Study of Liver Diseases (AASLD) Practice Guidance provides an approach to the diagnosis and management of patients with hepatocellular carcinoma. In this article, FLLs are reviewed with a comprehensive analysis of ACR Appropriateness Criteria, ACG Clinical Guideline, AASLD Practice Guidance, and current medical literature from peer-reviewed journals. The article includes a discussion of imaging methods used for the assessment of FLL, current recommended imaging techniques, innovations in liver imaging, contrast agents, imaging features of common nonmetastatic benign and malignant FLL, as well as current management recommendations.

Abstract
BACKGROUND Hepatic adenomas (HAs) are benign, solid liver lesions, which carry a risk of hemorrhage and malignant transformation. This review article highlights the advances in the diagnosis and management of HAs. METHODS A comprehensive review was performed using MEDLINE/PubMed and Web of Science databases with a search period ending on September 30, 2023. Using PubMed, the terms "hepatocellular," "hepatic," and "adenoma" were searched. RESULTS HA has been classified into at least 8 subtypes based on molecular pathology, each exhibiting unique histopathologic features, clinical considerations, and risk of malignant transformation. The most common subtype is inflammatory HA, followed by hepatocyte nuclear factor 1α-inactivated HA, β-catenin exon 3-mutated HA (βex3-HA), β-catenin exon 7- or 8-mutated HA, sonic hedgehog HA, and unclassified HA. Magnetic resonance imaging is the best imaging method for diagnosis and can distinguish among HA subtypes based on fat and telangiectasia pathologic characteristics. The risk of malignant transformation varies among molecular subtypes, ranging from <1% to approximately 50%. Up to 42% of HAs present with spontaneous intratumoral hemorrhage and peritoneal hemorrhage. In general, only 15% to 20% of patients require surgery. HA larger than 5 cm are more likely to be complicated by bleeding and malignant transformation, regardless of subtype, and should generally be resected. In particular, βex3-HA carries a high risk of malignant transformation and can be considered a true precancerous lesion. CONCLUSION The management of HAs is based on a multidisciplinary approach. Clinical decision-making should integrate information on gender, tumor size, and HA subtyping. In the future, patients with HA will benefit from novel medical therapies tailored to the individual molecular subtypes.

The Interplay between Perioperative Oxidative Stress and Hepatic Dysfunction after Human Liver Resection: A Prospective Observational Pilot Study. Antioxidants (Basel) 2024; 13:590. [PMID: 38790695 PMCID: PMC11118143 DOI: 10.3390/antiox13050590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 05/02/2024] [Accepted: 05/07/2024] [Indexed: 05/26/2024] Open
Abstract
Post-hepatectomy liver failure (PHLF) remains the major contributor to death after liver resection. Oxidative stress is associated with postoperative complications, but its impact on liver function is unclear. This first in-human, prospective, single-center, observational pilot study evaluated perioperative oxidative stress and PHLF according to the ISGLS (International Study Group for Liver Surgery). Serum 8-isoprostane, 4-hydroxynonenal (4-HNE), total antioxidative capacity, vitamins A and E, and intraoperative, sequential hepatic tissue 4-HNE and UCP2 (uncoupling protein 2) immunohistochemistry (IHC) were assessed. The interaction with known risk factors for PHLF and the predictive potential of oxidative stress markers were analyzed. Overall, 52 patients were included (69.2% major liver resection). Thirteen patients (25%) experienced PHLF, a major factor for 90-day mortality (23% vs. 0%; p = 0.013). Post-resection, pro-oxidative 8-isoprostane significantly increased (p = 0.038), while 4-HNE declined immediately (p < 0.001). Antioxidative markers showed patterns of consumption starting post-resection (p < 0.001). Liver tissue oxidative stress increased stepwise from biopsies taken after laparotomy to post-resection in situ liver and resection specimens (all p < 0.001). Cholangiocarcinoma patients demonstrated significantly higher serum and tissue oxidative stress levels at various timepoints, with consistently higher preoperative values in advanced tumor stages. Combining intraoperative, post-resection 4-HNE serum levels and in situ IHC early predicted PHLF with an AUC of 0.855 (63.6% vs. 0%; p < 0.001). This was also associated with grade B/C PHLF (36.4% vs. 0%; p = 0.021) and 90-day mortality (18.2% vs. 0%; p = 0.036). In conclusion, distinct patterns of perioperative oxidative stress levels occur in patients with liver dysfunction. Combining intraoperative serum and liver tissue markers predicts subsequent PHLF. Cholangiocarcinoma patients demonstrated pronounced systemic and hepatic oxidative stress, with increasing levels in advanced tumor stages, thus representing a worthwhile target for future exploratory and therapeutic studies.

Abstract
BACKGROUND The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes. METHODS LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January-December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien-Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141). RESULTS A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively. CONCLUSIONS This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives.

Abstract
Hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma are the most common benign solid liver tumors. However, their surgical indications have been the subject of debate. Minimally invasive liver resection reduces the cost of surgery and may lead to overtreatment of benign liver tumors. Recently, there has been a growing understanding of the etiology, pathogenesis, and natural history of these tumors. Great progress has also been made in imaging. The use of MRI and contrast agents has improved the accuracy of non-invasive diagnosis of these tumors, and especially in the identification of specific molecular subtypes of liver adenoma. These factors have resulted in alterations of surgical indications for these tumors. This article examines recent literature and it discusses the surgical indications for hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma while summarizing modifications in clinical management.

Abstract
BACKGROUND To evaluate the safety and the long-term outcomes of transarterial embolization (TAE) with lipiodol-bleomycin emulsion (LBE) plus N-Butyl cyanoacrylate (NBCA) in the treatment of children with large symptomatic focal nodular hyperplasia (FNH). METHODS This is a retrospective case serial study. Children (aged <18 years) with FNH were treated. Indications for TAE were patients who were presenting with FNH related abdominal pain and the maximum diameter of FNH is more than 7 cm, and who were not candidates for surgical treatment. Technical success, adverse events, symptoms relief rate, and changes in the lesion size after TAE were evaluated. RESULTS Between January 2003 and February 2018, 17 pediatric patients were included. Technical success was achieved in all patients. Mean follow-up was 67.5 months. All patients had complete resolution of abdominal symptom. The mean largest diameter of the lesions decreased from 10.5 cm to 1.9 cm (P < 0.01). The mean volume reduction rate was 96.9%. The complete resolution of the FNH was observed in 16 patients. No further therapy was needed for all patients. CONCLUSIONS TAE with LBE plus NBCA appears to be a safe and effective treatment in pediatric patients with large symptomatic FNH. It could be considered as the first-line treatment for symptomatic large FNH.

Abstract
OBJECTIVES To compare the efficacy of transarterial embolization (TAE) with polyvinyl alcohol (PVA) particles alone and lipiodol-bleomycin emulsion (LBE) plus PVA particles for patients with unresectable large symptomatic focal nodular hyperplasia (FNH). METHODS We performed a retrospective analysis of patients who underwent TAE either with PVA particles alone (group A, n = 46) or LBE plus PVA particles (group B, n = 35) for large (≥ 7 cm) symptomatic FNH between January 2002 and February 2019. Propensity score matching (PSM) (1:1) was performed to adjust for potential baseline confounders. Technical success, adverse events (AEs), symptom relief, and changes in the lesion size after TAE were evaluated. Statistical analysis included Wilcoxon rank sum test and χ2 test. RESULTS After PSM, no significant differences in baseline characteristics were found between the groups (31 in group A and 31 in group B, with a mean age of 31 years). Technical success was achieved in all patients (100%), without major AEs in both groups. Complete resolution of the abdominal symptoms was reported in 77.4% in group A and 100% in group B (p = 0.037) during a mean follow-up period of 72 months; complete resolution (CR) of the FNH rate was significantly higher in group B than in group A (93.6% vs. 67.7%; p = 0.019). CONCLUSION Compared with the use PVA particles alone, TAE with LBE plus PVA particles in the treatment of patients with large symptomatic FNH had a significantly higher rates of CR of the FNH and complete relief of the symptoms. KEY POINTS • Transarterial embolization (TAE) with lipiodol-bleomycin emulsion (LBE) plus PVA particles for the large symptomatic FNH yielded better results than with PVA particles alone, in terms of complete resolution of FNH lesions (93.6% vs 67.7%) and complete relief of the abdominal symptoms (100% vs 77.4%) during a mean follow-up period of 72 months (38-170 months). • No major complications were recorded in both groups, and no significant difference in the incidence of postembolization syndrome were observed between the two groups.

Abstract
OBJECTIVES This study aimed to assess the safety and efficacy of stereotactic radiofrequency ablation (SRFA) in patients with hepatocellular adenomas (HCA). METHODS Retrospective analyses of all patients referred for SRFA treatment at our institution between January 2010 and October 2020 revealed 14 patients (10 women; mean age 34.4 [range, 17-73 years]) with 38 HCAs treated through 18 ablation sessions. Ablations were considered successful if a safety margin >5 mm was achieved. Demographic, interventional, and outcome data were collected and analyzed. Primary and secondary technical efficacy rates were assessed based on follow-up images consisting of contrast-enhanced CT or MR scans. RESULTS The mean tumor size was 22 mm (range, 7-75 mm). Overall, 37/38 (97.4%) tumors were successfully ablated at the initial SRFA (primary efficacy rate of 97.4%). The median follow-up duration was 49.6 months. No deaths or adenoma-related complications (hemorrhage or malignant transformation) were observed. Disease-free survival rates at 1, 3, and 5 years from the date of the first SRFA were 100%, 85.8%, and 85.8%, respectively. Two patients developed new distant tumors retreated with consecutive re-ablation. No major complications occurred during any of the 18 ablation sessions. CONCLUSIONS Percutaneous thermal ablation is efficient in the treatment of HCAs and may thus be considered a valid first-line treatment option. In addition, SRFA allows for an effective, minimally invasive treatment of large and multiple hepatic tumors within one session.

Abstract
Haemangioma is the most frequent benign hepatic tumour. Haemangioma is generally asymptomatic but it can sometimes cause disabling symptoms depending on its size and location. Surgery and interventional radiology are the cornerstone of the treatment in this situation. Radiation therapy, already used with good efficacy and safety to treat hepatic malignant lesions as hepatocarcinoma and metastases, is a relevant option in case of contraindication to surgery because of multiple or very large lesions. In this context, we report the case of a patient presenting with multiple symptomatic hepatic haemangiomas, successfully treated by radiation therapy in our department. These good results justified a review of the literature to report series of patients treated in this indication and to describe the main treatment regimens used.

Abstract
Liver transplantation (LT) is currently considered the gold standard treatment for end-stage liver failure. Compared to the first decades of its use, LT is associated with lower comorbidity and mortality, with a 5-year survival over 70%. Worldwide, liver cirrhosis and hepatocellular carcinoma represent the major indications to LT. However, almost 1% of LT is performed for rare diseases or rare indications, which include non-hepatocellular malignancy, vascular disorders, metabolic and congenital liver disorders. These diseases can lead to hepatocellular necrosis, biliary tree abnormality and/or hepatomegaly. Most of these diseases are not associated with liver failure but in highly selected patients, LT represent an effective therapy improving the overall survival and quality of life. Rare indications for LT often overlap with rare diseases. However, rare LT indications for non-rare diseases are rising in the last decades, especially for benign primary liver tumor, colon rectal liver metastasis, neuroendocrine liver metastasis, and cholangiocarcinoma (CCA). Non-rare diseases with rare indication for LT and rare adult disease with an indication for LT are categorized and discussed in detail, focusing on some disorders for which the literature provides a more definitive evidence base. Early referral to a transplant center is encouraged to provide an effective therapeutic option in these non-standard indications for LT.

Deep learning-assisted differentiation of pathologically proven atypical and typical hepatocellular carcinoma (HCC) versus non-HCC on contrast-enhanced MRI of the liver. Eur Radiol 2021; 31:4981-4990. [PMID: 33409782 DOI: 10.1007/s00330-020-07559-1] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 11/06/2020] [Accepted: 11/23/2020] [Indexed: 02/05/2023]
Abstract
OBJECTIVES To train a deep learning model to differentiate between pathologically proven hepatocellular carcinoma (HCC) and non-HCC lesions including lesions with atypical imaging features on MRI. METHODS This IRB-approved retrospective study included 118 patients with 150 lesions (93 (62%) HCC and 57 (38%) non-HCC) pathologically confirmed through biopsies (n = 72), resections (n = 29), liver transplants (n = 46), and autopsies (n = 3). Forty-seven percent of HCC lesions showed atypical imaging features (not meeting Liver Imaging Reporting and Data System [LI-RADS] criteria for definitive HCC/LR5). A 3D convolutional neural network (CNN) was trained on 140 lesions and tested for its ability to classify the 10 remaining lesions (5 HCC/5 non-HCC). Performance of the model was averaged over 150 runs with random sub-sampling to provide class-balanced test sets. A lesion grading system was developed to demonstrate the similarity between atypical HCC and non-HCC lesions prone to misclassification by the CNN. RESULTS The CNN demonstrated an overall accuracy of 87.3%. Sensitivities/specificities for HCC and non-HCC lesions were 92.7%/82.0% and 82.0%/92.7%, respectively. The area under the receiver operating curve was 0.912. CNN's performance was correlated with the lesion grading system, becoming less accurate the more atypical imaging features the lesions showed. CONCLUSION This study provides proof-of-concept for CNN-based classification of both typical- and atypical-appearing HCC lesions on multi-phasic MRI, utilizing pathologically confirmed lesions as "ground truth." KEY POINTS • A CNN trained on atypical appearing pathologically proven HCC lesions not meeting LI-RADS criteria for definitive HCC (LR5) can correctly differentiate HCC lesions from other liver malignancies, potentially expanding the role of image-based diagnosis in primary liver cancer with atypical features. • The trained CNN demonstrated an overall accuracy of 87.3% and a computational time of < 3 ms which paves the way for clinical application as a decision support instrument.

Abstract
Background Sex differences are becoming of rising interest in many fields of medicine. It remains unknown whether sex has a role in postoperative and long-term outcome after hepatic resection (HR). The aim of this study was to investigate sex differences in disease presentation, surgical and oncological outcome after curative HR. Methods Retrospective analysis of 1010 patients who underwent HR between 2005 and 2018 at two tertiary hospitals in Austria. Demographics and survival data were obtained from a prospectively maintained database. Univariate analysis was used to identify sex differences for the entire cohort and for sub-cohorts. Disease-free- and overall survival was assessed by the Kaplan-Meier estimate and results were compared by log-rank tests. Results 436 females and 574 males were analyzed. Women were younger (p<0.001), had less liver cirrhosis (p<0.001), cardiac comorbidities (p<0.001), diabetes (28 (p<0.001) and obesity (p<0.001). Type of HR and surgical management did not vary by sex. Ninety-day morbidity (p = 0.179) and -mortality (p = 0.888) were comparable. In patients with malignant disease, no differences in disease-free- and overall survival was observed, neither for the entire cohort nor for the subgroups according to tumor entity or type of resection. Only in HCC patients, females showed an inferior OS (p = 0.029). Conclusion This study delivers new insights on the impact of sex differences in liver surgery. Despite the fact that male patients have a higher incidence of preoperative morbidities, we did not observe specific disparities in terms of immediate postoperative as well as long term oncological outcome between sexes.

Abstract
Haemangiomas of the liver are benign tumours, which are often diagnosed randomly. With an increase in size haemangiomas could become symptomatic. In this case therapeutic options, surgical or interventional, have to be weighted to a conservative approach. We present a case of a 36-year old woman with a symptomatic giant haemangioma of the right liver lobe. Because of the size of the tumor and the small future liver remnant we decided to perform a major liver resection after hypertrophy induction with a preoperative portal vein embolization; an option mainly used for major hepatectomies in malignant tumors of the liver. But however, this case shows, that using a hypertrophy concept also for benign liver tumours is the safer approach, if an extended resection is necessary and the future liver remnant is critical.

Abstract
Compression of the Vena cava leading to pulmonary embolism is a rare symptom of hemangioma. Resection of Hemangioma to normalize the flow of the vena cava is a rare indication, but an effective and safe therapy. The patient required no anticoagulation after the surgery.
Introduction Hemangiomas are common hepatic lesions and are mostly asymptomatic. Operative removal should only be performed when the lesions are symptomatic, and removal of the hemangioma is deemed to be more beneficial than the risk of the operation itself. Presentation of the case The multiple hemangiomas of our patient were discovered nine years before first symptoms. The patient presented with pulmonary artery embolism due to a compression of the vena cava inferior by a hemangioma in segment I. No other cause of thromboembolic events could be diagnosed. We performed surgical enucleation of the hemangioma, which resulted in the normalization of blood flow in the inferior vena cava. As the inducing factor for clot development was removed, no permanent thrombosis prophylaxis was implicated. Discussion Pulmonary embolisms owing to compression of the inferior vena cave are rare. Conclusion Until now to our knowledge, pulmonary embolisms have never been described as an indication for hepatic hemangioma enucleation.

Abstract
With increased use of medical imaging, the incidental detection of benign solid liver tumors has become more frequent. Facing with benign disease, the indications for surgery are still object of discussion in light of the stable natural course of most lesions and obvious drawbacks of any surgical intervention; therefore, in most situations, a conservative approach is recommended, and surgery is mainly reserved for those cases with persistent or worsening symptoms, or who are at risk for complications as malignant transformation. The advent of ablative techniques has widened the range of treatment options available to these patients, presenting as a valid alternative to resection in terms of safety and efficacy in selected cases, particularly in patients who are considered poor surgical candidates and with smaller lesions. This review outlines the role of percutaneous ablative methods for benign solid liver tumors that are encountered in adults, providing a per histology analysis of the existing evidence. The up-to-date strategies for management of the most common benign solid tumors are recapitulated.

JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2020; 27:359-370. [PMID: 32065510 PMCID: PMC7496457 DOI: 10.1002/jhbp.727] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 01/04/2020] [Accepted: 02/09/2020] [Indexed: 12/26/2022]
Abstract
Lactate measurements have proven utility as a triage tool, therapeutic guide, and prognostic indicator, with broad use in Acute Care and transplantation. Its value in guiding therapy and predicting outcomes following liver resection is less well‐defined. This systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines assessed the relationship between peri‐operative lactate levels and morbidity and mortality after liver resection. Seven relevant studies comprising 2573 patients in total were identified. Six studies assessed intra‐operative or early postoperative lactate levels, one publication examined pre‐operative levels. All studies demonstrated a significant association between peri‐operative lactate levels and adverse outcomes. The influence of pre‐operative diabetes and cirrhosis on postoperative lactate levels was shown in one study each, no study assessed the association of lactate with post‐hepatectomy liver failure according to defined criteria. The heterogeneity of study measurements and end‐points precluded a meta‐analysis from being performed. Early postoperative lactate >3‐3.7 mmol/L is associated with mortality but validation of clear cut‐off levels for outcome prediction is pending. Literature suggests lactate is a useful predictive marker for outcomes post liver surgery, especially when measured in the early postoperative phase. Further research is required to standardize the use of lactate measurements in a meaningful therapeutic manner.

HMGB1-induced endothelial cell pyroptosis is involved in systemic inflammatory response syndrome following radiofrequency ablation of hepatic hemangiomas. Am J Transl Res 2019; 11:7555-7567.

Abstract
The goal of this study was to assess the role of high-mobility group box 1 (HMGB1)-induced endothelial cell (EC) pyroptosis in systemic inflammatory response syndrome (SIRS) following radiofrequency (RF) ablation of hepatic hemangiomas. We enrolled 76 patients with hepatic hemangioma who underwent RF ablation. Serum concentrations of HMGB1, interleukin (IL)-1β, IL-18 and lactate dehydrogenase (LDH) were determined at different time points. Immunohistochemistry staining (IHC) was performed to evaluate the expressions of HMGB1, NLRP3, caspase-1, GSDMD, IL-18 and IL-1β in hepatic hemangioma and sub-ablated hemangioma tissues. In vitro experiments used human umbilical vein endothelial cells (HUVECs) treated with sub-ablative hyperthermia to mimic insufficient RF ablation of hepatic hemangiomas. ELISA and western blotting were performed to quantify HMGB1, NLRP3, caspase-1, GSDMD, IL-18, IL-1β and LDH levels with or without the addition of ethyl pyruvate (EP), a HMGB1 inhibitor, in the medium. Flow cytometry and fluorescent staining were performed to assess pyroptosis of HUVECs. Twenty-nine patients experienced SIRS after RF ablation (29/76, 38.2%). HMGB1, IL-1β and IL-18 levels were significantly correlated with SIRS. IHC staining revealed an obvious increase in HMGB1, NLRP3, caspase-1, GSDMD, IL-18, and IL-1β in the ECs of sub-ablated hemangioma but not in hepatic hemangioma. In vitro experiments showed that subablative hyperthermia led to HMGB1-induced pyroptosis of HUVECs and EP attenuated the pyroptosis of HUVECs. Taken together, these data demonstrate HMGB1-induced ECs pyroptosis may occur during SIRS following RF ablation of hepatic hemangiomas.

Abstract
This study investigated the relationship between endothelial pyroptosis and the occurrence of systemic inflammatory response (SIR) after radiofrequency (RF) ablation of hepatic hemangiomas. Thirty-two patients with hepatic hemangiomas were treated with RF ablation and blood samples of the patients were collected at different time points. Immunohistochemistry staining was performed to evaluate the expression of caspase-1, gasdermin D (GSDMD), IL-1β and IL-18 in hepatic hemangioma and subablated hemangioma tissue. In vitro experiments, human umbilical vein endothelial cells (HUVECs) were treated with sub-ablative hyperthermia with or without the addition of caspase-1 inhibitor, Ac-YVAD-CMK in the medium. Lactate dehydrogenase (LDH), IL-18, IL-1β, caspase-1 and GSDMD were measured by enzyme-linked immunosorbent assay, real-time PCR and Western blot methods. An elevation of general SIR parameters (CRP and WBC), pyroptosis-related inflammatory cytokines (IL-1β and IL-18) and LDH were observed 1-day post-RF ablation and their peak values were significantly correlated with ablated volume (p < .001) and ablation time (p < .001). Moreover, levels of pyroptosis-related inflammatory cytokines correlated well with general SIR parameters, respectively (p < .001). Immunohistochemical analysis showed the increased expression of caspase-1, GSDMD, IL-18 and IL-1β in the endothelial cells of subablated hemangioma. In vitro experiments showed that subablative hyperthermia induced the caspase-1-associated endothelial pyroptosis and Ac-YVAD-CMK attenuated pyroptosis. In conclusion, SIR in patients treated by RF ablation for hepatic hemangiomas was significantly associated with the ablated volume and ablation time and endothelial pyroptosis may involve in the occurrence of SIR following RF ablation of hepatic hemangiomas.

Abstract
The key aspect of this technique is to selectively control the arterial inflow. Mass enucleation represents the most challenging part of the procedure. ICG allows identifying the surgical plane between the mass and normal parenchyma. The robotic platform allows to replicate the enucleation performed in open surgery.
Introduction Liver hemangiomas are benign liver lesions that require surgical excision when large and symptomatic. Often, these tumors are removed through large anatomical resections which sacrifice more liver parenchyma than needed. Tumor enucleation, which takes advantage of a digitoclasia-like technique along the plane between the tumor pseudo-capsule and liver parenchyma, poses challenges when performed laparoscopically. We propose a parenchymal sparing, minimally invasive, robotic-assisted technique to remove liver hemangiomas. Presentation of cases Three male patients with symptomatic hemangiomas were treated in our center between 2015 and 2018. The lesions were located in segment II, III and segment IV-V respectively. Robotic-assisted hemangioma enucleation was accomplished successfully in all three patients. The procedures were performed with a parenchyma-sparing intent and a formal segmentectomy was not required. There were no conversions to open surgery. Discussion The robotic platform provides a powerful tool in the enucleation of liver hemangiomas. The enhanced vision and the superior suturing ability allow to develop safely the plane between the tumor pseudo-capsule and the liver parenchyma, with outstanding selective control of all the vascular supply and drainage encountered during the dissection. Furthermore, precision of the hilar dissection allows selective lobar or sectorial arterial control which helps minimize intraoperative bleeding. Conclusion In our experience, robot-assisted enucleation of liver hemangiomas offers low morbidity, fast recovery, excellent cosmetic results, and it could become a therapeutic option when the location of the hemangioma allows this approach.

Abstract
Hormones are substances that serve as chemical communication between cells. They are unique biological molecules that affect multiple organ systems and play a key role in maintaining homoeostasis. In this role, they are usually produced from a single organ and have defined target organs. However, hormones can affect non-target organs as well. As such, biochemical and hormonal abnormalities can be associated with anatomic changes in multiple target as well as non-target organs. Hormone-related changes may take the form of an organ parenchymal abnormality, benign neoplasm, or even malignancy. Given the multifocal action of hormones, the observed imaging findings may be remote from the site of production, and may actually be multi-organ in nature. Anatomic findings related to hormone level abnormalities and/or laboratory biomarker changes may be identified with imaging. The purpose of this image-rich review is to sensitize radiologists to imaging findings in the abdomen and pelvis that may occur in the context of hormone abnormalities, focusing primarily on sex hormones and their influence on these organs.

Abstract
Hepatic adenomas are rare, benign liver masses of rising incidence in the United States. We present a report of a 22-year-old asymptomatic female with a massive (14.2 × 11.4 cm), centrally located hepatic adenoma. The unique presentation of the adenoma in close proximity to the hepatic vasculature meant the patient was not a candidate for surgical resection. An arterial embolization was used as an alternative approach to initial treatment. Arterial branches supplying the adenoma were identified via computed tomography and embolized with embospheres and coils. The treatment resulted in a large reduction in size and density of the adenoma identified at a 1-month follow-up. The case supports further use of arterial embolization as an initial treatment for large adenomas to improve the outcome of subsequent surgical approaches.
