Abstract
Bile leaks arise from various causes such as trauma, complications after hepatobiliary surgery, and intrahepatic malignancies or their associated liver-directed treatments. Bile leaks can result in significant morbidity and mortality. Delayed diagnosis is not uncommon due to nonspecific manifestations; therefore, a high clinical suspicion is needed. A multidisciplinary approach for treatment of biliary leaks with prompt referral to tertiary care centers with experienced hepatobiliary surgeons, advanced endoscopists, and interventional radiologists is needed to address these challenging complications. Management of biliary leaks can range from conservative management to open surgical repair. Minimally invasive procedures play a crucial role in biliary leak treatment, and the interventional radiologist can help guide appropriate management on the basis of a clear understanding of the pathophysiology of biliary leaks and a current knowledge of the armamentarium of treatment options. In most cases, a simple diversion of bile to decompress the biliary system may prove effective. However, persistent and high-output biliary leaks require delineation of the source with tailored treatment options to control the leak. This may be done by additional diversions, occluding the source, reestablishing connections, or using a combination of therapies to bridge to more definitive surgical interventions. The authors describe the different treatment options and emphasize the role of interventional radiology. ©RSNA, 2024.

Efficacy and Safety of Local Liver Radioablation in Hepatocellular Carcinoma Lesions within and beyond Limits of Thermal Ablation. Dig Dis 2024:1-12.

Abstract
INTRODUCTION CT-guided interstitial brachytherapy (iBT) radiotherapy has been established in the treatment of liver tumors. With iBT, hepatocellular carcinoma (HCC) lesions can be treated beyond the limits of thermal ablation (i.e., size and location). However, a comprehensive analysis of the efficacy of iBT in patients within and beyond thermal ablation limits is lacking. MATERIALS AND METHODS A total of 146 patients with 216 HCC lesions have been analyzed retrospectively. Clinical and imaging follow-up data has been collected. Lesions were evaluated in terms of suitability for thermal ablation or not. The correlation between local tumor control (LTC), time to progression (TTP), overall survival (OS), and clinical and imaging parameters have been evaluated using univariable and multivariable Cox regression analyses. RESULTS LTC rates at 12 months, 24 months, and 36 months were 87%, 75%, and 73%, respectively. 65% of lesions (n = 141) were not suitable for radiofrequency ablation (RFA). The median TTP was 13 months, and the median OS was not reached (3-year OS rate: 70%). No significant difference in LTC, TTP, or OS regarding RFA suitability existed. However, in the overall multivariable analysis, lesion diameter >5 cm was significantly associated with lower LTC (HR: 3.65, CI [1.60-8.31], p = 0.002) and shorter TTP (HR: 2.08, CI [1.17-3.70], p = 0.013). Advanced BCLC stage, Child-Pugh Stage, and Hepatitis B were associated with shorter OS. CONCLUSION iBT offers excellent LTC rates and OS in local HCC treatment regardless of the limits of thermal ablation, suggesting further evidence of its alternative role to thermal ablation in patients with early-stage HCC.

Abstract
We report a case of hemoperitoneum after percutaneous radiofrequency ablation in a patient with hepatocellular carcinoma. A 60-year-old female was hospitalized for the treatment of thrombasthenia and cirrhosis caused by chronic Hepatitis C, and computed tomography revealed hepatocellular carcinoma, which was treated by percutaneous radiofrequency ablation. After the ablation, hemoperitoneum was suspected because of the low hemoglobin level with abdominal pain. Approximately 6 h after the ablation treatment, the patient suddenly fell into a shock state and died. In this case, medical treatment-related death including malpractice was suspected, and forensic autopsy was performed. The abdominal cavity contained 910 mL of dark red fluid blood and 210 g of soft hemocoagula. Moreover, several puncture marks were observed on the liver surface and diaphragm, and there was no clear damage to the main arteries and veins. Considering the macroscopic and microscopic findings, the cause of death was assumed as hemorrhagic shock due to the hemoperitoneum caused by the damage to the liver by radiofrequency ablation. It is important to consider all the indications and adverse effects of radiofrequency ablation.

Radiofrequency ablation of subcapsular versus nonsubcapsular hepatocellular carcinomas ≤ 3 cm: analysis of long-term outcomes from two large-volume liver centers. Eur Radiol 2024; 34:1578-1586. [PMID: 37646813 DOI: 10.1007/s00330-023-10165-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 07/07/2023] [Accepted: 07/20/2023] [Indexed: 09/01/2023]
Abstract
OBJECTIVES To compare the safety and efficacy of RFA for single HCCs ≤ 3 cm in subcapsular versus nonsubcapsular locations using a propensity score matched analysis. MATERIALS AND METHODS This retrospective study included patients with solitary HCCs ≤ 3 cm in size who underwent percutaneous RFA from 2005 to 2015 as initial treatment at two large-volume liver centers. Patients were divided into two groups, consisting of those with subcapsular and nonsubcapsular tumor locations. Complications, local tumor progression (LTP), and overall survival (OS) were compared in these two groups before and after propensity score matching (PSM). RESULTS The study population consisted of 964 patients (712 men [74%]) of mean age 58.3 years. Of these 964 patients, 561 (58%) had nonsubcapsular and 403 (42%) had subcapsular HCCs. PSM generated 402 pairs of patients. Major complication rate was low, but significantly higher in the subcapscular group (p = 0.047). Rates of technical effectiveness in these two groups were 99% and 98%, respectively (p = 0.315). However, during follow-up, cumulative 1-, 3-, 5-, and 10-year LTP and OS rates did significantly differ in both entire and PSM cohorts, resulting in the latter 8%, 15%, 20%, and 26% in the nonsubcapsular group vs. 13%, 24%, 30%, and 31% in the subcapsular group (p = 0.015), and 99%, 91%, 80%, and 59% vs. 98%, 85%, 73%, and 50% in the two groups (p = 0.004), respectively. CONCLUSION Rates of major complications, LTP, and OS differed significantly following first-line RFA treatment of single HCCs ≤ 3 cm in favor of the nonsubcapsular locations. CLINICAL RELEVANCE STATEMENT This large-scale study provides evidence that radiofrequency ablation for small (≤ 3 cm) hepatocellular carcinomas is safer and more effective in nonsubcapsular location than in subcapsular location. KEY POINTS • There exist conflicting outcomes on the effectiveness of RFA for early HCC depending on tumor location. • Rate of local tumor progression was significantly higher in the subcapsular hepatocellular carcinomas. • Overall survival rate was significantly poorer in the subcapsular hepatocellular carcinomas.

Abstract
Neuropsychiatric toxicities are uncommon but well-documented side effects of antibiotics. Society of Interventional Radiology guidelines recommend various antibiotic regimens for patients undergoing interventional radiological procedures. These same classes of drugs are also used to treat infectious complications in patients. Antibiotics have a wide spectrum of affective and cognitive toxicities, the most severe of which can lead to hospitalization or suicide. Fluoroquinolones have the highest incidence of these toxicities.

Abstract
Although hepatocellular carcinoma (HCC) is associated with a poor prognosis, management of early-stage HCC is often successful with highly efficacious treatment modalities such as liver transplantation, surgical resection, and radiofrequency ablation. However, unfavorable clinical outcomes have been observed under certain circumstances, even after efficient treatment. Factors that predict unsuitable results after treatment include tumor markers, inflammatory markers, imaging findings reflecting tumor biology, specific outcome indicators for each treatment modality, liver functional reserve, and the technical feasibility of the treatment modalities. Various strategies may overcome these challenges, including the application of reinforced treatment indication criteria with predictive markers reflecting tumor biology, compensation for technical issues with up-to-date technologies, modification of treatment modalities, downstaging with locoregional therapies (such as transarterial chemotherapy or radiotherapy), and recently introduced combination immunotherapies. In this review, we discuss the challenges to achieving optimal outcomes in the management of early-stage HCC and suggest strategies to overcome these obstacles.

Abstract
BACKGROUND Microwave ablation (MWA) via ultrasound guidance is an important tool in the treatment of liver metastases. The most common postoperative complications are abdominal hemorrhage and bile leakage, whereas thrombosis in the suprahepatic inferior vena cava (IVC) is very rare, and clinical management is very difficult when the head end of the thrombus reaches the right atrium. CASE PRESENTATION This is a case report of a 52-year-old man with hepatic metastasis 21 months after radical resection of rectal cancer. After chemotherapy combined with targeted therapy, metastasis in segment IV (S4) of the liver was treated with microwave ablation. Two months after treatment, the hepatic metastasis in S4 showed a microwave ablation zone on MRI.Enhanced MRI showed venous thrombosis located in the left hepatic vein and IVC, and the head of the thrombus reached the right atrium. After two weeks of anticoagulation and thrombolytic treatment, the follow-up MRI showed that the venous thrombus had nearly disappeared. CONCLUSION When liver metastases are close to the hepatic vein, clinicians should pay attention to the occurrence of hepatic vein and IVC thrombosis following MWA; through early diagnosis and anticoagulation, pulmonary thromboembolism (PTE) can be minimized.

Abstract
Background To assess the frequency of major complications after thermal ablation of liver tumours and to determine risk factors for adverse events. Methods A retrospective study was conducted between January 2015 and January 2021. A total of 2,084 thermal ablation sessions in 1,592 patients with primary and metastatic liver tumours were evaluated. The frequency of major complications was evaluated according to the Society of Interventional Radiology Standards, and putative predictors of adverse events were analysed using simple and multivariate logistic regression. Results Thermal ablation-related mortality was 0.1% (2/2,084), with an overall major complication rate of 5.6% (117/2,084). The most frequent major complication was symptomatic pleural effusion (2.9%, 60/2,084). Multivariate logistic regression analysis revealed that a total maximum diameter of lesions >3 cm, microwave ablation (MWA) and MWA combined with radiofrequency ablation, intrahepatic cholangiocarcinoma and postoperative systemic inflammatory response syndrome were independent prognostic factors for major complications. Conclusions Thermal ablation of liver tumours is a safe procedure with an acceptable incidence of major complications. The risk factors identified in this study will help to stratify high-risk patients.

Abstract
Patients with cirrhosis show an increased susceptibility to infection due to disease-related immune-dysfunction. Bacterial infection therefore represents a common, often detrimental event in patients with advanced liver disease, since it can worsen portal hypertension and impair the function of hepatic and extra-hepatic organs. Among pharmacological strategies to prevent infection, antibiotic prophylaxis remains the first-choice, especially in high-risk groups, such as patients with acute variceal bleeding, low ascitic fluid proteins, and prior episodes of spontaneous bacterial peritonitis. Nevertheless, antibiotic prophylaxis has to deal with the changing bacterial epidemiology in cirrhosis, with increased rates of gram-positive bacteria and multidrug resistant rods, warnings about quinolones-related side effects, and low prescription adherence. Short-term antibiotic prophylaxis is applied in many other settings during hospitalization, such as before interventional or surgical procedures, but often without knowledge of local bacterial epidemiology and without strict adherence to antimicrobial stewardship. This paper offers a detailed overview on the application of antibiotic prophylaxis in cirrhosis, according to the current evidence.

Abstract
Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related mortality and has an increasing incidence worldwide. Locoregional therapies, defined as imaging-guided liver tumour-directed procedures, play a leading part in the management of 50-60% of HCCs. Radiofrequency is the mainstay for local ablation at early stages and transarterial chemoembolization (TACE) remains the standard treatment for intermediate-stage HCC. Other local ablative techniques (microwave ablation, cryoablation and irreversible electroporation) or locoregional therapies (for example, radioembolization and sterotactic body radiation therapy) have been explored, but have not yet modified the standard therapies established decades ago. This understanding is currently changing, and several drugs have been approved for the management of advanced HCC. Molecular therapies dominate the adjuvant trials after curative therapies and combination strategies with TACE for intermediate stages. The rationale for these combinations is sound. Local therapies induce antigen and proinflammatory cytokine release, whereas VEGF inhibitors and tyrosine kinase inhibitors boost immunity and prime tumours for checkpoint inhibition. In this Review, we analyse data from randomized and uncontrolled studies reported with ablative and locoregional techniques and examine the expected effects of combinations with systemic treatments. We also discuss trial design and benchmarks to be used as a reference for future investigations in the dawn of a promising new era for HCC treatment.

Abstract
PURPOSE Impact of previous history of choledochojejunostomy (PCJ) on the incidence of organ/space surgical site infection (SSI) after hepatectomy remains unclear. The aim of this study was to investigate the incidence and causes of SSI after hepatectomy. METHODS Patients who underwent hepatectomy of ≤1 Couinaud's sector between January 2011 and September 2019 were retrospectively analyzed. Incidence of and risk factors for organ/space SSI (Clavien-Dindo grade ≥2) after hepatectomy were investigated. RESULTS Among 750 hepatectomies, 18 patients (2.4%) had a medical history of PCJ. Incidence of organ/space SSI was higher in patients with PCJ (50%) than in those without PCJ (3%, P < 0.001), and the trend was consistent even after estimated propensity score matched cohort. Multivariate analysis showed PCJ was a strong risk factor for organ/space SSI (grade ≥2), with the highest odds ratios (OR) among all other clinicopathological risk factors (OR, 32.25; P < 0.001). Among hepatectomies with PCJ, pneumobilia (OR, 12.25; P = 0.015), operation time ≥171 min (OR, 12.25; P = 0.016), and liver steatosis (OR, 24.00; P ≤ 0.005) were associated with organ/space SSI after hepatectomy. CONCLUSION Previous history of choledochojejunostomy was a strong risk factor for organ/space SSI after hepatectomy. The high rate of organ/space SSI after hepatectomy with PCJ might be attributed to intrahepatic bile duct contamination, increased operation time, and histological liver steatosis.

Abstract
Importance Hepatocellular carcinoma (HCC) is usually accompanied by liver cirrhosis, which makes treatment of this disease challenging. Liver transplantation theoretically provides an ultimate solution to the disease, but the maximal surgical stress and the scarcity of liver graft make this treatment option impossible for some patients. In an ideal situation, a treatment that is safe and effective should provide a better outcome for patients with the dilemma. Objective This article aims to give a comprehensive review of various types of loco-ablative treatment for HCC. Evidence Review Loco-ablative treatment bridges the gap between surgical resection and transarterial chemotherapy. Various types of ablative therapy have their unique ability, and evidence-based outcome analysis is the most important key to assisting clinicians to choose the most suitable treatment modality for their patients. Findings Radiofrequency ablation (RFA) has a relatively longer history and more evidence to support its effectiveness. Microwave ablation (MWA) is gaining momentum because of its shorter ablation time and consistent ablation zone. High-intensity focused ultrasound (HIFU) ablation is a relatively new technology that provides non-invasive treatment for patients with HCC. It has been carried out at centers of excellence and it is a safe and effective treatment option for selected patients with HCC and liver cirrhosis. Conclusion and Relevance Selective use of different loco-ablative therapies will enhance clinicians' treatment options for treatment of HCC.

Abstract
PURPOSE Most patients with intrahepatic cholangiocarcinoma (ICC) are not eligible for surgical resection due to advanced stage. We aimed to evaluate the feasibility, local tumor control, and long-term survival of intraoperative radiofrequency ablation (IORFA) with surgical resection to treat unresectable intrahepatic cholangiocarcinoma (ICC). METHODS From 2009 to 2016, 20 consecutive patients (12 primary ICC, 8 recurrent ICC) underwent curative IORFA with hepatic resection for surgically unresectable ICC. Patients were not qualified to undergo surgical resection due to multiple lesions causing postoperative hepatic insufficiency and undesirable tumor locations for surgical resection or percutaneous RFA. Of the 51 treated tumors (mean, 2.6±0.9 tumors/patient), 24 were treated by IORFA and 27 were surgically removed. The technical success and effectiveness, overall survival, progression-free survival (PFS), and complications were assessed retrospectively. The overall survival and PFS rates were estimated by the Kaplan-Meier method. RESULTS The technical success and effectiveness of IORFA were 100%. The overall survival rates at 6 months, 1, 3, and 5 years were 95%, 79%, 27%, and 14%, respectively. The median overall survival time was 22.0±3.45 months. The PFS rates at 6 months, 1, 3, and 5 years were 70%, 33%, 13%, and 13%, respectively. The median PFS was 9.0±1.68 months. The prognosis was significantly worse for patients with recurrent ICC than for patients with primary ICC. One patient (5%) had major complications due to IORFA such as liver abscess and biliary stricture. CONCLUSION IORFA with surgical resection can be a feasible option for ICC cases that are not amenable to treatment with surgical resection alone. This strategy provides acceptable local tumor control and overall survival.

Abstract
Image-guided radiofrequency ablation is frequently used to treat small hepatocellular carcinoma and metastases. Complications associated with this thermal-based technology for liver cancers arise via direct mechanical injury by the electrodes or collateral thermal damage to surrounding structures. This case report describes an unusual presentation of hepatic arterial mycotic pseudoaneurysm as melaena after percutaneous image-guided radiofrequency ablation for liver metastases in a patient with a previous surgical history of hepaticojejunostomy for cholangiocarcinoma. The patient had a lifesaving procedure to treat the hepatic pseudoaneurysm with transarterial glue embolization.

Abstract
PURPOSE To examine predictors of midterm occlusion in portal and hepatic veins within or adjacent to the ablation zone after irreversible electroporation (IRE) of liver tumors. MATERIALS AND METHODS This retrospective cohort analysis included 39 patients who underwent CT-guided IRE of liver tumors. Vessels within or adjacent to the ablation zone were identified on CT images acquired immediately after the procedure, and the positional relationships with the ablation zone (within/adjacent), locations (proximal/distal), and diameters (< 4 mm or ≥ 4 mm) were evaluated. Using contrast-enhanced follow-up scans, each vessel was classified as patent, stenosed, or occluded. Associations between vessel occlusion and each variable were investigated. RESULTS Overall, 33 portal veins and 64 hepatic veins were analyzed. Follow-up scans showed occlusion in 12/33 (36.7%) portal veins and 17/64 (26.6%) hepatic veins. Vessels within the ablation zone were occluded significantly more frequently than vessels adjacent to the ablation zone (portal: 55.6% [10/18] vs 13.3% [2/15], P = .04; hepatic: 45.4% [15/33] vs 6.4% [2/31], P = .011). Vessels with a diameter < 4 mm were also occluded significantly more frequently than vessels with a diameter ≥ 4 mm (portal: 72.7% [8/11] vs 18.1% [4/22], P = .011; hepatic: 54.8% [17/31] vs 0% [0/33], P < .001). The respective positive and negative predictive values for occlusion of vessels categorized as both within and < 4 mm were 88% (7/8) and 82% (20/25) for portal veins and 79% (15/19) and 96% (43/45) for hepatic veins. CONCLUSIONS Midterm vessel occlusion after liver IRE could be predicted with relatively high accuracy by assessing ablation location and vessel diameter.

Abstract
BACKGROUND Radiofrequency ablation (RFA) and microwave ablation (MWA) represent the standard of care for patients with early hepatocellular carcinoma (HCC) who are unfit for surgery. The incidence of reported adverse events is low, ranging from 2.4% to 13.1% for RFA and from 2.6% to 7.5% for MWA. Gastrointestinal tract (GIT) injury is even more infrequent (0.11%), but usually requires surgery with an unfavourable prognosis. Due to its low incidence and the retrospective nature of the studies, the literature reporting this feared complication is heterogeneous and in many cases lacks information on tumour characteristics, comorbidities and treatment approaches.
CASE SUMMARY A 77-year-old man who had undergone extended right hepatectomy for HCC was diagnosed with early disease recurrence with a small nodule compatible with HCC in the Sg4b segment of the liver with a subcapsular location. He was treated with percutaneous RFA and a few week later he was urgently admitted to the Surgery ward for abdominal pain and fever. A subcutaneous abscess was diagnosed and treated by percutaneous drainage. A fistulous tract was then documented by the passage of contrast material from the gastric antrum to the abdominal wall. The oesophagogastroduodenoscopy confirmed a circular wall defect at the lesser curvature of gastric antrum, leading directly to the purulent abdominal collection. An over-the-scope clip (OTSC) was used to successfully close the defect
CONCLUSION This is the first reported case of RFA-related GIT injury to have been successfully treated with an OTSC, which highlights the role of this endoscopic treatment for the management of this complication.

Abstract
PURPOSE The aims of this study were to compare the perioperative outcomes after hepatectomy with prior bilioenteric anastomosis to those without prior anastomosis, and to elucidate the mechanisms and preventative measures of its characteristic complications. METHODS The demographic data and perioperative outcomes of 525 hepatectomies performed between January 2007 and December 2018, including 40 hepatectomies with prior bilioenteric anastomosis, were retrospectively analyzed. RESULTS A propensity score matching analysis demonstrated that hepatectomies with prior bilioenteric anastomosis were associated with a higher frequency of major complications (p = 0.015), surgical site infection (p = 0.005), organ/space surgical site infection (p = 0.003), and bile leakage (p = 0.007) compared to those without. A multivariate analysis also elucidated that prior bilioenteric anastomosis was one of the independent risk factors of organ/space surgical site infection. In the patients with prior bilioenteric anastomosis, bile leakage was associated with organ/space surgical site infection at a significantly higher rate than those without prior bilioenteric anastomosis (p < 0.001). CONCLUSIONS Prior bilioenteric anastomosis is a strong risk factor for organ/space surgical site infections, which might be induced by bile leakage. To prevent infectious complications after hepatectomy with prior bilioenteric anastomosis, meticulous liver transection to reduce bile leakage rate is thus considered to be mandatory.

Abstract
INTRODUCTION This study aimed to assess safety, local tumour progression (LTP) and risk factors for LTP after radiofrequency ablation (RFA) of liver tumours in a single centre. METHODS All consecutive patients treated with RFA for liver tumours between January 2009 and October 2012 were included. Previously treated lesions that progressed were excluded. Using electronic medical records, the following data was captured: patient demographics, pre-procedural laboratory results, Child-Pugh status, tumour characteristics, development of tumoral seeding, RFA complications and LTP. Possible risk factors for LTP were identified using Cox regression. RESULTS In total, 555 liver tumours were treated in 337 patients. 483 (87.0%) hepatocellular carcinomas, 52 (9.4%) colorectal metastases and 20 (3.6%) other tumour types were treated. Mean tumour size was 2.1 ± 1.1 (range 0.4-6.8) cm. Mean follow-up duration was 387 days. 416 (75.0%) lesions had no LTP at the last imaging. 70 (12.6%) patients had minor complications requiring observation, while 7 (1.3%) patients had significant complications requiring prolonged hospitalisation or further interventions. Only one case of tumour seeding was detected. Using multivariate Cox regression, the following factors were statistically significant in predicting LTP: hilar location (relative ratio [RR] 3.988), colorectal metastases (RR 2.075), size (RR 1.290) and younger age (RR 0.982). CONCLUSION RFA of liver tumours is safe and effective, with a low significant complication rate of 1.3%. Hilar lesions are most prone to LTP, followed by lesions that were larger in size and colorectal metastases. 75.0% of patients showed no LTP at the last follow-up.

Abstract
INTRODUCTION To evaluate the feasibility and safety of ultrasound-guided iodine-125 interstitial implants for high-risk hepatocellular carcinoma. METHODS From October, 2016, to August, 2018, 49 patients suffering from a total of 66 hepatocellular carcinoma lesions were treated with ultrasound-guided iodine-125 interstitial implantation. Treatment planning system was applied to make preoperative plan. The response evaluation criteria in solid tumors were used to evaluate the curative effect. The evaluated outcomes included postoperative complications and complete disease control rate, 6-month disease-free survival, and 6-month overall survival. RESULTS All 49 patients underwent iodine-125 seed implantation successfully. Patients were followed up for 5 to 27.5 months. No patients developed serious complications and only 2 (4.1%) patients had slight pain. The complete response was seen in 21 lesions (31.8%), partial response in 26 lesions (39.4%), stable disease in eight lesions (12.1%), and progressive disease in 11 lesions (16.7%). The overall disease control rate was reached to 83.3%. The 6-month disease-free survival rate was 46.4% with a median disease-free survival time of 5.0 months. The 6-month overall survival rate was 83.6% with a median overall survival time of 15.0 months. CONCLUSIONS Iodine-125 interstitial implantation is a kind of safe and feasible treatment for high-risk hepatocellular carcinoma.

Abstract
Objective: This study aimed to evaluate the risk factors of biloma formation and secondary infection after thermal ablation for malignant hepatic tumors. Patients and methods: A total of 58 patients with 68 bilomas after thermal ablation were recruited as the complication group, and 61 patients with 72 lesions without major complications were selected randomly as the control group. The potential risk factors for biloma formation were analyzed with the chi-square test and multivariate logistic regression analysis. To determine the optimum management method for biloma, patients with secondary infection were included for the subgroup analysis of risk factors. Results: A history of transcatheter arterial chemoembolization (TACE) treatment (odds ratio [OR]: 3.606, 95% confidence interval [CI]: 1.165-11.156, p = .026) and tumor location (OR: 37.734, 95% CI: 13.058-109.034, p = .000) were independent predictors of biloma formation. Among the 58 patients with biloma, 49 (84.5%) showed no symptoms (i.e., the asymptomatic group), while the remaining 9 (15.5%) developed symptoms related to secondary infections (i.e., the symptomatic group). There were significant differences in the history of biliary manipulation (p = .031) between the symptomatic and asymptomatic groups. Conclusion: A history of TACE treatment and the distance from the biliary tract were independent predictors of biloma formation after thermal ablation. Therefore, protecting the bile duct (i.e., cooling of the bile duct and combing thermal ablation with chemical ablation) should be considered for high-risk patients. Moreover, active monitoring and management should be performed for patients with bilomas who underwent biliary surgery before.

Transient elastography predicts survival after radiofrequency ablation of hepatocellular carcinoma developing on cirrhosis. J Gastroenterol Hepatol 2020; 35:142-150. [PMID: 31237018 DOI: 10.1111/jgh.14763] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2019] [Revised: 05/26/2019] [Accepted: 06/12/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIM The prognostic value of transient elastography (TE) in cirrhotic patients with hepatocellular carcinoma (HCC) treated by percutaneous radiofrequency ablation (RFA) is currently unknown. METHOD(S) We included patients with histologically proven cirrhosis and with a first diagnosis of HCC inside Milan criteria treated by percutaneous RFA, and with TE available the year before treatment with 10 shots and interquartile range/median < 30%. Association between variables and clinical events was assessed by the Kaplan-Meier method with the log-rank test and using Cox univariate and multivariate analyses. RESULTS One hundred fifty-nine patients were included, with a median age of 65 years; 77.4% were men. Causes of cirrhosis were alcohol consumption (48.1%), hepatitis C (43.7%), hepatitis B (12.7%), and non-alcoholic steatohepatitis (32.3%). Median value of TE was 26 kPa (4-75 kPa). Overall survival at 1, 2, and 5 years was, respectively, 93%, 81%, and 44%; overall recurrence was 28%, 49%, and 80%. The TE value was not associated with tumor recurrence (0.13). In contrast, in univariate analysis, TE value, age, Child-Pugh B, and alkaline phosphatase were predictive factors in overall survival. In multivariate analysis, TE value (hazards ratio [HR] = 1.02, 95% confidence interval (IC): 1.01-1.04, 0.001), age (HR = 1.05, 95% IC: 1.03-1.08, P = 0.00006), and Child-Pugh B score (HR = 2.78, 95% IC: 1.27-6.08, P = 0.01) were independently associated with higher risk of death. A TE value ≥ 40 kPa was associated with shorter median overall survival (34 months) compared to a TE value < 40 kPa (59 months, P = 0.0008). CONCLUSION(S) Transient elastography (TE) predicts overall survival but not tumor recurrence in cirrhotic patients with HCC treated by RFA.

Abstract
INTRODUCTION Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is considered a safe and minimally invasive procedure. We previously reported that the mortality and complication rates for RFA were 0.038% (5/13,283 patients) and 3.54% (579 complications/16,346 procedures), respectively, from 1999 to 2010 (previous period). In this study, we investigated the clinical criteria for RFA and the mortality and complication rates from 2011 to 2015 (recent period). METHODS Data were collected from 25 centers by using a questionnaire developed by the Chugoku-Shikoku Society for Local Ablation Therapy of HCC. The criteria for RFA, RFA modification, use of image-guidance modalities, mortality, and complications during the previous and recent periods were compared. RESULTS We evaluated 11,298 procedures for 9,411 patients, including those that involved new devices (bipolar RFA and internally adjustable electrode system). The criterion of hepatic function for RFA increased from a Child-Pugh score ≤8 during the previous period to ≤9 during the recent period. The criteria regarding the tumor location and other risk factors have been expanded recently because of the increased use of several modifications of the RFA procedure and image-guidance modalities. The mortality rate was 0.064% (6/9,411 patients), and the complication rate was 2.92% (330 complications/11,298 procedures). There was no difference in mortality rates between the 2 periods (p = 0.38), but the complication rates was significantly lower during the recent period (p = 0.038). DISCUSSION AND CONCLUSIONS Our findings confirmed that RFA, including the use of new devices, is a low-risk procedure for HCC, despite the expansion of the criteria for RFA during the recent period.

Abstract
Percutaneous radiofrequency ablation (RFA) has been accepted as a minimally invasive therapeutic treatment for liver malignancies. Although RFA is usually applied for the treatment of small liver tumors (<3 cm), several technical developments have expanded the use of RFA. RFA is now used for the treatment of large liver tumors, and the number of complications associated with this treatment has decreased. These refinements may ultimately lead to better long-term prognosis. Here, we review recent refinements of liver RFA and provide technical tips.

Abstract
Local non-surgical interventional percutaneous ablation represents nowadays an important part of the potential treatment strategies. Although surgical ablation represents the gold standard, in the past decade there was an expansion in the use of non-surgical ablative techniques: radiofrequency, microwave, laser, cryoablation, irreversible electroporation, and interventional radiotherapy (brachytherapy) in primary as well as secondary liver cancers. With the growing experience in the field, there was implemented a new pillar for cancer treatment, together with surgery, chemotherapy as well as radiotherapy, so-called interventional oncology (IO). To date, there are no published papers regarding a comparative interdisciplinary evaluation of all these non-surgical interventional local ablation therapies. Our paper offers a critical interdisciplinary overview of the treatments in both primary and secondary liver tumors, including from a cost-effective point of view. Furthermore, the present status of education in IO and a comparison of actual economic aspects of the treatments are also provided.

Abstract
Background To assess the safety and efficacy of cryoablation (CA) devices for the treatment of liver cancer at special sites in a retrospective study. Methods Special site liver cancer was defined as the tumors directly abutting surrounding structures (such as the liver capsule, gallbladder, vessel, diaphragm, intestine, and adrenal gland) with a maximum distance of 1.0 cm between the tumor and these organs. Sixty-six patients (49 men, 17 women; mean age, 60.8 years; age range, 27-82 years) were included. CA procedure was performed to treat 69 tumors under the guidance of computed tomography or ultrasound. Local tumor progression was assessed during the follow-up. A visual analog scale (VAS) evaluated the pain degree. Complications were assessed during and after every procedure. Results The number of tumors under the liver capsule and adjacent to the gallbladder, portal or hepatic vein, diaphragm, intestine, and adrenal gland were 29, 5, 8, 14, 7, and 6, respectively. The median follow-up time was 14 months (range, 2-28 months). In the 69 procedures, the technical success rate was 100%. The cumulative local tumor progression rates at 6, 9, 15, and 24 months were 10.2%, 16.5%, 20.9%, and 30.5%, respectively. No cases of serious complications occurred. During operation, the occurrence rates of subcapsular hemorrhage and pneumothorax were 2.9% and 1.4%, respectively. After the operation, the occurrence rate of biloma, capsular injury, subcapsular planting metastasis, and pneumothorax were 1.4%, 18.8%, 1.4%, and 2.8%, respectively. The average score of 66 patients with a VAS was 2.15±0.63 during the operation. Conclusions Percutaneous CA is safe and effective for patients with special site liver cancer.

Abstract
Hepatocellular carcinoma (HCC) has a high incidence of recurrence following therapy. Therefore, secondary surveillance (scheduled follow-up imaging after treatment) is an important part of disease management. The recent approval in the United States for use of a microbubble-based contrast agent for US liver imaging promotes the increased use of contrast-enhanced US (CEUS) in patients with HCC. Although the criteria for the diagnosis of HCC at CEUS are well described, there is a paucity of published literature describing the role of CEUS in ablative therapy and secondary surveillance. In the setting of ablative therapy, CEUS can have vital roles, including patient selection, intraprocedural guidance, and immediate postprocedural assessment. Although CEUS is not widely used, the authors found that it can be used to accurately detect residual or recurrent tumor, characterize the geographic pattern of recurrence (intrazonal, extrazonal, segmental, or remote), and assess for tumor in vein. In addition, similar to primary surveillance, secondary surveillance includes assessment of the entire liver for evaluation of new nodules. Arterial phase hyperenhancement is the reference standard characteristic of disease recurrence at secondary surveillance with CEUS. ©RSNA, 2019 See discussion on this article by Rodgers.

Abstract
Percutaneous thermal ablation of hepatic tumors continues to play an integral role in the treatment of early-stage primary or secondary hepatic malignancies. Interventional radiologists must be familiar with potential complications of this procedure, associated risk factors, and methods for prevention. The authors report a devastating case of septic shock and death following percutaneous microwave ablation of a solitary hepatocellular carcinoma in a liver transplant patient with a bilioenteric anastomosis (BEA). We review the literature regarding prophylactic antibiotic regimens and bowel preparation prior to performing thermal ablation in patients with BEAs.

Abstract
Recently, the interventional therapies are used more often in clinical practice for hepatocellular carcinoma. The most commonly used methodologies include radiofrequency ablation, microwave ablation, laser ablation, and cryotherapy. Most of the interventional operations need local anesthesia combined with intravenous sedation. Also, some interventional therapy centers apply general anesthesia. However, different anesthesia methods can cause diverse effects on patients' pain management, recovery time, and hospitalization time. For the better understanding of the current anesthesia application status, we summarize and analyze multiple anesthesia methods while being applied in interventional therapy for hepatocellular carcinoma; in addition, their characters are also compared in this paper.

Abstract
Liver transplantation is a surgical option with curative intent used in the management of some cases of hepatocellular carcinoma and cholangiocarcinoma (hilar, rarely intrahepatic). A number of different therapeutic modalities including ablative techniques, arterially directed therapies, radiation and chemotherapy are used in the neoadjuvant setting prior to liver transplantation with the goals of preventing tumour progression, decreasing post-transplant recurrence and possibly downstaging patients with tumour burden beyond what is acceptable by current transplant criteria. Pathologists evaluating hepatic explants must be aware of these neoadjuvant therapies and the alterations induced by them in both tumourous and non-tumourous tissue. In this review, we discuss common neoadjuvant therapies used in in this setting, as well as the gross and microscopic changes induced by these presurgical treatments within hepatic neoplasms as well as the background hepatic parenchyma and nearby structures. Select secondary tumours involving the liver which are pretreated will also be discussed. Finally, proper reporting of these changes will be mentioned.

Abstract
BACKGROUND AND PURPOSE Stereotactic body radiotherapy (SBRT) is an emerging ablative modality for hepatocellular carcinoma (HCC). This study aimed to synthesize available evidence to evaluate the clinical feasibility and efficacy of SBRT for HCC. MATERIALS AND METHODS A systematic search was performed of the PubMed, Medline, Embase, and Cochrane Library databases. Primary endpoints were overall survival (OS) and local control (LC), and the secondary endpoint was grade ≥3 complications. RESULTS Thirty-two studies involving 1950 HCC patients who underwent SBRT were included. Pooled 1-, 2-, and 3-year OS rates were 72.6% (95% confidence interval [CI]: 65.7-78.6), 57.8% (50.9-64.4), and 48.3% (40.3-56.5), respectively. Pooled 1-, 2-, and 3-year LC rates were 85.7% (95% CI: 80.1-90.0), 83.6% (77.4-88.3), and 83.9% (77.6-88.6), respectively. The median value of median tumor sizes among studies was 3.3 cm (range: 1.6-8.6). Median radiation doses, calculated in dose equivalent with 2 Gy per fraction, ranged from 48 to 114.8 Gy10 (median 83.3 Gy10). Subgroup comparison regarding tumor size showed significant differences for 1- and 2-year OS rates and 1-, 2-, and 3-year LC rates, and that regarding radiation dose showed no difference for OS and a marginal difference for 1-year LC rate. Pooled rates of hepatic and gastrointestinal grade ≥3 complications were 4.7% (95% CI: 3.4-6.5) and 3.9% (2.6-5.6), respectively. Child-Pugh class was significantly correlated with hepatic complication of grade ≥3 in meta-regression analysis (p = 0.013). CONCLUSION SBRT for HCC was a feasible option conferring excellent LC persisting up to 3 years. Both OS and LC were affected by tumor size, and radiation dose marginally affected LC. Severe complications rarely occurred, but liver function should be considered to avoid serious hepatic toxicity.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common type of malignancy. Several therapies are available for HCC and are determined by stage of presentation, patient clinical status and liver function. Local–regional treatment options, including transcatheter arterial chemoembolization, radiofrequency ablation or microwave ablation, are safe and effective for HCC but are accompanied by limitations. The synergistic effects of combined transcatheter arterial chemoembolization and radiofrequency ablation/microwave ablation may overcome these limitations and improve the therapeutic outcome. The purpose of this article is to review the current literature on these combined therapies and examine their efficacy, safety and influence on the overall and recurrence-free survival in patients with HCC.

Abstract
There is not yet a consensus regarding a difference in prognosis for patients with hepatocellular carcinoma (HCC) with and without bile duct invasion (BDI). The present study aimed to clarify the prognostic importance of BDI on the short and long-term outcome of patients with HCC who underwent surgical resection. The present study evaluated HCC with BDI, including peripheral microscopic biliary invasion and revealed that the prognosis of patients with BDI was poorer compared with those without BDI. It should be noted that peripheral BDI also had a negative impact on the prognosis of patients with HCC. The clinical prognosis assessment revealed that BDI should be considered when assigning a disease stage. BDI, either macroscopic or microscopic, indicated a poor prognosis in patients with HCC who underwent curative resection, however it was not a surgical contraindication. Macroscopic BDI and hyperbilirubinemia were significantly associated with a dismal prognosis, which should alert surgeons.

Abstract
PURPOSE To examine the safety, feasibility, and oncologic control following percutaneous image-guided thermal ablation of hepatocellular carcinoma (HCC) in a transplanted allograft. MATERIALS AND METHODS Retrospective review was performed to identify patients who underwent liver transplantation for HCC and subsequently underwent percutaneous hepatic thermal ablation for recurrent HCC within the allograft between January 1st, 2000-September 1st, 2016. Eleven patients with hepatic allograft HCC underwent twelve percutaneous thermal ablation procedures to treat 16 lesions. Patient, procedural characteristics, and local oncologic efficacy were reviewed. Complications were characterized via the Common Terminology for Clinically Adverse Events nomenclature [CTCAE] v4.03). RESULTS Eleven transplant recipients underwent treatment of 16 HCC tumors in their allografts during 12 ablation sessions. Mean follow-up time was 25 months (range 2-96 months). Local oncologic control was achieved in 10 of 11 tumors (91%) with imaging follow-up. One patient (8%) with Roux-en-Y biliary reconstruction developed a major complication with hepatic abscess. CONCLUSION Thermal ablation of recurrent HCC in transplanted allografts can be accomplished safely with acceptable rates of local control for patients with duct-to-duct biliary reconstruction. Due to the high number of patients deemed surgically unresectable, the morbidity of surgical resection, the side effects of targeted therapies, and significant mortality associated with recurrences in the transplanted allograft, patients may benefit from percutaneous thermal ablative treatments. Further study is needed to assess the role of thermal ablation in allograft HCC recurrences as primary therapy or in a multimodality approach with emerging systemic therapies.

Abstract
PURPOSE To analyze CT features that predict major gastrointestinal tract (GIT) complication after hepatic radiofrequency ablation (RFA). MATERIALS AND METHODS Of 3933 patients who underwent RFA for hepatic malignancy from January 2005 to September 2016, 52 patients (1.32%) who had GIT complications were retrospectively enrolled. Electronic medical records and CT results were reviewed for location (left vs. right lobe, subcapsular vs. non-subcapsular) and tumor size, distance from the hepatic capsule, number and length of needles, ablation time, presence of artificial ascites, previous history of percutaneous treatment or operation, injured organs, length and thickness of injured GIT, presence of adjacent infiltration, ascites, mucosal discontinuity, and free air, and eccentricity. Patients were divided into those that recovered with conservative treatment (minor group) and those that required operation (major group). Chi-square test, Fisher's exact test, and Mann-Whitney U test analyzed differences between the two groups; however, the most significant variable was found using binary logistic regression analysis. RESULTS Of 52 patients who had GIT complications after hepatic RFA, 2 patients (0.05%) had major GIT complications, while the remaining 50 patients (1.27%) had minor complications. Most (47/52, 90.4%) of the tumors were located at subcapsular portion. 66% of tumors were located at the left hepatic lobe. Stomach was the most frequent injured organ (28/52, 53.8%), followed by colon (17/52, 32.7%) and small bowel (7/52, 13.5%). Patients with major GIT complications had significantly thicker (1.8 vs. 1.1 cm) and concentric (2/2, 100% vs. 1/50, 2.0%) bowel wall thickening with mucosal discontinuity (2/2, 100% vs. 0/50, 0%) than those with minor complications (P < 0.05). CONCLUSION GIT complication after hepatic RFA is rare and often requires conservative treatment. However, patients who show >1.65-cm-thick, concentric bowel wall thickening with mucosal disruption on CT after hepatic RFA may have major GIT injury that requires bowel surgery.

Abstract
Radiofrequency ablation (RFA), a local ablative modality, is gaining acceptance for the treatment of liver malignancies. Despite a relatively low complication rate, tumor seeding resulting from RFA in hepatocellular carcinoma (HCC) treatment can occur. A 44-year-old woman was diagnosed with HCC. Spiral computed tomography (CT) revealed a 2.3 × 2.0-cm mass in the S5 segment, which was treated with RFA on May, 2005. Follow-up imaging, performed at 6-month intervals after RFA, showed complete tumor necrosis. In October 2009, CT revealed a heterogeneous mass, 5.7 cm in diameter, in the right ovary. Since the lesion was limited to the right ovary without evidence of spread, bilateral salpingo-oophorectomy was performed. Histopathology indicated that the metastatic spread from the HCC to the ovary was positive for hepatocyte-specific antigen on immunohistochemistry. The ovary is a rare site for HCC metastasis. Moreover, needle tract implantation of HCC in the ovary is very rare.

Abstract
Purpose This study sought to prospectively evaluate the feasibility and safety of a preoperative mathematic model for computed tomographic(CT) guided microwave(MW) ablation treatment of hepatic dome tumors. Methods This mathematic model was a regular cylinder quantifying appropriate puncture routes from the bottom up. A total of 103 patients with hepatic dome tumors were enrolled and randomly divided into 2 groups based on whether this model was used or not: Group A (using the model; n = 43) versus Group B (not using the model; n = 60). All tumors were treated by CT-guided MW ablation and follow-up contrast CT were reviewed. Results The average number of times for successful puncture, average ablation time, and incidence of right shoulder pain were less in Group A than Group B (1.4 vs. 2.5, P = 0.001; 8.8 vs. 11.1 minutes, P = 0.003; and 4.7% vs. 20%, P = 0.039). The technical success rate was higher in Group A than Group B (97.7% vs. 85.0%, P = 0.032). There were no significant differences between the two groups in primary and secondary technique efficacy rates (97.7% vs. 88.3%, P = 0.081; 90.0% vs. 72.7%, P = 0.314). No major complications occurred in both groups. Conclusion The mathematic model of regular cylinder is feasible and safe for CT-guided MW ablation in treating hepatic dome tumors.

Abstract
Purpose To investigate the efficacy and safety of irreversible electroporation (IRE) in the treatment of hepatic tumors not suitable for thermal ablation (radiofrequency ablation [RFA] or microwave ablation). Materials and Methods This was an institutional review board-approved prospective study in 29 patients (15 men, 14 women; mean age, 63 years ± 12 [standard deviation]) with 43 primary (n = 8) or secondary (n = 35) malignant liver tumors who underwent computed tomography (CT)-guided IRE. All target tumors were located immediately adjacent to major hepatic veins, portal veins, or both; thus, they were not considered suitable for RFA or microwave ablation. Patients underwent postinterventional CT and magnetic resonance (MR) imaging. Systematic follow-up MR imaging was performed for 24 months on average to assess complete ablation, intrahepatic tumor recurrence, and complications. The 95% confidence intervals (CIs) were determined for the rate of bile duct strictures, incomplete ablation, and tumor recurrence. Results Complete ablation was achieved in 40 (93%; 95% CI: 85, 100) of 43 target tumors, with a safety margin of 5-10 mm, and was confirmed at immediate postinterventional CT and MR imaging. In 13 (33%; 95% CI: 18, 47) of 40 completely ablated tumors, intrahepatic tumor recurrence was observed at 2-18 months. However, only two (15%; 95% CI: 0, 35) of these 13 tumors were observed within the ablation zone. In the remaining 11 (85%; 95% CI: 65, 100), tumor growth was observed alongside the needle tract. None of the two true local recurrences occurred at the site of the vessel. All adjacent vessels remained perfused at follow-up. Five (24%; 95% CI: 5, 39) of 21 patients with target tumors adjacent to portal veins developed mild to moderate cholestasis 2-6 weeks after IRE. Conclusion IRE is useful to avoid incomplete ablation secondary to heat-sink effects and damage to major blood vessels; however, needle tract seeding is observed in 26% of treated tumors, and IRE induces sufficient local heating to bile ducts in 24% of ablations. © RSNA, 2017.

Association between hospital volume and in-hospital mortality following radiofrequency ablation for hepatocellular carcinoma. BJS Open 2017; 1:50-54.

Abstract
Background Radiofrequency ablation (RFA) is a minimally invasive treatment for hepatocellular carcinoma (HCC). There is increasing evidence of an association between increasing hospital volume and lower postoperative mortality for many surgical procedures, but this is difficult to establish with minimally invasive treatments, where postoperative mortality is low. The aim of this study was to investigate the relationship between hospital volume and in-hospital mortality following RFA using a Japanese nationwide database. Methods Data from the Diagnostic Procedure Combination database were analysed from 1 July 2010 to 31 March 2012. Multivariable logistic regression was used to analyse the relationship between hospital volume and in-hospital mortality following RFA, with adjustment for patient background. Results Some 36 675 patients with HCC were identified in the database. The overall in-hospital mortality rate from RFA was 0·31 per cent. In-hospital mortality was significantly higher in low-volume than high-volume hospitals (odds ratio 2·57, 95 per cent c.i. 1·61 to 4·09; P < 0·001). Higher in-hospital mortality was significantly associated with older age and a higher Charlson Co-morbidity Index score. Conclusion RFA for HCC was associated with acceptably low mortality in Japan, but in-hospital mortality following RFA was affected by hospital procedural volume.
