Abstract
Percutaneous ablation under imaging guidance is a curative treatment that can induce complete tumor necrosis with advantages of minimal invasiveness and a low risk of complications. Thermal ablation, which includes radiofrequency ablation and microwave ablation, is a representative technique that has sufficient antitumor effects in cases of hepatocellular carcinoma with ≤3 lesions measuring ≤3 cm and preserved liver function. The short- and long-term outcomes of patients are comparable with those achieved with surgical resection. Despite their nonmalignant nature, some benign liver tumors require treatment for symptoms caused by the presence of the tumor and/or continuous enlargement. Ablation may be the treatment of choice because it has lower burden on patients than surgical treatment. This review describes the recent concepts, progress, and limitations of ablation-based treatment for benign liver tumors.

Abstract
BACKGROUND Hepatic hemangioma is a common benign liver tumor. The majority of cases are asymptomatic and require no specific treatment. The aim of this study was to evaluate the feasibility, safety and efficacy of microwave ablation (MWA) for symptomatic or enlarging giant hepatic hemangioma (≥10 cm). METHODS From December 2013 to June 2016, 12 patients with giant hepatic hemangioma (≥10 cm) underwent ultrasound-guided percutaneous MWA, and ablation-related complications were observed. All patients were followed up with magnetic resonance or enhanced CT imaging at one month postoperatively to evaluate efficacy. RESULTS This study included a total of 13 giant hepatic hemangiomas (mean: 11.7 ± 1.6 cm) in 12 patients who initially underwent 16 sessions of MWA; three lesions were treated with two sessions of planned ablation. The average ablation time for a single hepatic hemangioma was 39.0 ± 14.4 minutes. Two patients had acute postoperative non-oliguric renal insufficiency without intra-abdominal hemorrhage, liver failure or other complications. Initially, complete ablation was achieved in ten lesions in nine patients (76.9%, 10/13). One patient underwent a second session of MWA at 5 months postoperatively due to fast growing residual tissue; complete necrosis was achieved after treatment. The remaining two cases did not receive any invasive treatment due to small residual volumes. The total complete ablation rate was 84.6% (11/13). CONCLUSION Image-guided MWA is a safe, feasible, effective treatment for giant hepatic hemangioma; these findings may open a new avenue for treatment.

Abstract
INTRODUCTION Radiofrequency ablation (RFA) is an effective and minimally invasive technique for the management of hepatic hemangiomas (HHs). This study aims to assess the safety and efficacy of laparoscopic RFA for HHs. MATERIAL AND METHODS Forty-four patients with 50 hepatic hemangiomas (5-10 cm in diameter) undergoing laparoscopic RFA from January 2012 to May 2015 at three tertiary hospitals in China were retrospectively analyzed. RESULTS Thirty-three patients with subcapsular hemangiomas were treated with a laparoscopic approach, and 11 patients with lesions in the liver parenchyma were treated with a combined laparoscopy and an ultrasound-guided percutaneous approach. No conversion to open surgery or two-step surgery occurred during the study period. Patients with small hemangiomas (< 7 cm) required a significantly shorter operating time (71.1 ± 20.18 min vs. 106 ± 23.55 min, p = 0.000) and fewer punctures compared with patients with large hemangiomas (> 7 cm) (4.61 ± 1.09 vs. 6.73 ±1.01, P < 0.05). According to the Dindo-Clavien classification, 15 patients experienced 34 Grade 1 complications, and two had complications of Grade 3a. All complications were resolved by conservative treatment. Forty-three (86.0%) HHs in 38 patients were completely ablated after RFA, and 7 (14.0%) HHs in 6 patients were incompletely ablated. All patients were followed up for 6-24 months (mean 15 ± 6 months). CONCLUSION The data showed that laparoscopic RFA is an effective treatment for small (< 10 cm) HHs. While the incidence of postoperative complications remains high, the majority of complications are minor. Patients undergoing laparoscopic RFA for HHs, even for the small ones, should be carefully selected.

Abstract
Recent studies have shown that radiofrequency (RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.

Abstract
Background: Radiofrequency ablation (RFA) is a relatively new procedure for treating benign thyroid nodules. The purpose of this study was to evaluate the safety and efficacy of RFA for treating benign thyroid nodules so as to serve as a reference for future clinical practice. Methods: This study retrospectively analyzed the clinical data of patients receiving percutaneous RFA for treating thyroid nodules from November 2014 to July 2015 in our medical center. One hundred and eight patients with a total of 380 nodules received ultrasound-guided RFA for treating thyroid nodules. Comparisons of the volume change of thyroid nodules before and after RFA treatment, post-treatment complication, and change of thyroid function, were carried out afterwards. Results: Before treatments, all patients received fine needle aspiration biopsy (FNA) which supported the diagnosis of benign tumor. There were 13 males and 95 females included in the study. Twenty-six cases (24.07%) had single nodule, and 82 cases (75.93%) had multiple nodules. Before treatments, the thyroid functions (FT3, FT4, and TSH) were normal originally or adjusted to normal range by endocrinology treatment. The preoperative nodules had minimum volume of 0.01mL, maximum volume of 70.89 mL, and mean volume of 1.02 ± 4.24mL. The volume of nodules one month and three months after RFA were 0.29 ± 0.72mL and 0.15 ± 0.87mL, respectively. In addition, volume reduction ratio (VRR) of nodules one month and three months after RFA were 64.12% and 85.54%, respectively. Both volume of nodules and VRR had statistically significant differences for pre-operative and post-operative comparison (P<0.05). Thyroid functions were in normal range after treatments, and there was no serious complications. Conclusions: Ultrasound-guided RFA treating benign thyroid nodules had the advantages of definite efficacy, safety, strong in control ability, no incision, less damage to surrounding normal tissues and no effect on thyroid function. It can be used as one of the main treatment methods for treating benign thyroid nodules.

Abstract
The aim of the study was to evaluate the feasibility, safety, and efficacy of computed tomography (CT)-guided radiofrequency (RF) ablation combined with transcatheter arterial embolization (TAE) to treat large (≥10 cm) hepatic hemangiomas. We retrospectively reviewed our sequential experience with 15 large hepatic hemangiomas in 15 patients. The mean diameter of the 15 hemangiomas was 13.0 ± 2.2 cm (10.0-16.0 cm). RF ablation combined with TAE treatment was performed successfully in all patients. The mean diameter of the hemangiomas decreased from 13.0 ± 2.2 to 7.1 ± 2.0 cm (P < 0.001) after TAE treatment. Out of 15 hepatic hemangiomas, 14 (93.3%) showed no enhancement on CT or MRI indicating complete ablation after RF treatment. The mean diameter of the ablation zone decreased to 6.1 ± 2.0 cm 1 month after ablation and further decreased to 4.9 ± 1.6 cm 6 months after ablation. There were 6 complications related to the ablation in 4 patients. According to the Dindo-Clavien classification, all the complications were minor (Grade I). RF ablation combined with TAE is a safe and effective treatment for large hepatic hemangiomas. TAE can improve the disruption of lesion blood supply and reduce lesion size to facilitate subsequent RF ablation and reduce the risk of ablation-related complications.

Abstract
Huge hepatic hemangiomas (≥ 10 cm) are often growthful and harmful. Surgical resection is the traditional treatment for this disease, however, this treatment modality is rather invasive and the operative morbidity and mortality are relatively high. To avoid surgical risk, many minimally invasive procedures have been developed to treat hepatic hemangiomas. In the recent decade, radiofrequency ablation (RFA) has been performed successfully in patients with huge hepatic hemangiomas, showing many advantages over resection, including minimal invasiveness, low complication rate, reduced cost, short hospital stay and increased patient compliance. The treatment strategy for huge hepatic hemangioma is changing from the traditional surgical resection to the minimally invasive treatment with RFA. In the current review, we discuss the present situation and prospect of RFA application in the treatment of huge hepatic hemangiomas.

Abstract
Objectives The aim of this study was to evaluate the technical and clinical outcomes of using laparoscopic radiofrequency (RF) ablation for treating large subcapsular hepatic hemangiomas. Methods We retrospectively reviewed our sequential experience of treating 124 large subcapsular hepatic hemangiomas in 121 patients with laparoscopic RF ablation. Results The mean diameter of the 124 hemangiomas was 9.1 ± 3.2 cm (5.0–16.0 cm). RF ablation was performed successfully in all patients. There were 55 complications related to the ablation in 26 patients, including 5 of 69 (7.3%) patients with hemangioma <10 cm and 21 of 52 (40.4%) patients with hemangiomas ≥10 cm (P < 0.001). No injuries to abdominal viscera occurred in all the 121 patients. According to the Dindo–Clavien classification, all the complications were minor in 26 patients (Grade I). Out of 124 hepatic hemangiomas, 118 (95.2%) were completely ablated, including 70 of 72 (97.2%) lesions < 10 cm and 48 of 52 (92.3%) lesions ≥ 10 cm (P = 0.236). Conclusion Laparoscopic RF ablation therapy is a safe, feasible and effective procedure for large subcapsular hepatic hemangiomas, even in the hepatic hemangiomas ≥ 10 cm. Its use avoids thermal injury to the abdominal viscera.

Abstract
BACKGROUND Four different sizes (4, 5, 8 and 10 cm in diameter) can be found in the literature to categorize a liver hemangioma as giant. The present review aims to clarify the appropriateness of the size category "giant" for liver hemangioma. DATA SOURCES We reviewed the reports on the categorization of hemangioma published between 1970 and 2014. The number of hemangiomas, size criteria, mean and range of hemangioma sizes, and number of asymptomatic and symptomatic patients were investigated in patients aged over 18 years. Liver hemangiomas were divided into four groups: <5.0 cm, 5.0-9.9 cm, 10.0-14.9 cm and ≥15.0 cm in diameter. Inclusion criteria were noted in 34 articles involving 1972 (43.0%) hemangiomas (>4.0 cm). RESULTS The patients were divided into the following groups: 154 patients (30.0%) with hemangiomas less than 5.0 cm in diameter (small), 182 (35.5%) between 5.0 cm and 9.9 cm (large), 75 (14.6%) between 10.0 and 14.9 cm (giant), and 102 (19.9%) more than 15.0 cm (enormous). There were 786 (39.9%) asymptomatic patients and 791 (40.1%) symptomatic patients. Indications for surgery related to symptoms were reported in only 75 (3.8%) patients. Operations including 137 non-anatomical resection (12.9%) and 469 enucleation (44.1%) were unclearly related to size and symptoms. CONCLUSIONS The term "giant" seems to be justified for liver hemangiomas with a diameter of 10 cm. Hemangiomas categorized as "giant" are not indicated for surgery. Surgery should be performed only when other symptoms are apparent.

Abstract
OBJECTIVE To evaluate the efficacy, safety and feasibility of microwave ablation (MWA) for large (5-10 cm in diameter) hepatic hemangioma. METHODS In all, 46 patients with 47 large hepatic hemangiomas were treated with ultrasound-guided percutaneous MWA. The effect of MWA for all patients was evaluated by enhanced magnetic resonance imaging or computed tomography within two months after ablation. RESULTS A total of 27 male and 19 female patients were enrolled, with an average age of 46 ± 11 years. The average size of hemangiomas was 6.3 ± 1.4 cm (range 5.0-9.6 cm). The initial complete ablation rate was 91.5% (43/47) and the volume of ablated lesions was significantly reduced. The rate of complete necrosis was not associated with the tumor size or location (P = 0.899 and 0.758, respectively). The total complete ablation rate was 95.7% (45/47). Major complications included acute renal dysfunction, hyperbilirubinemia and pleural effusion. No procedure-related death occurred. The average hospitalization stay was 5.7 ± 2.5 days (range 3-17 days). During a follow-up period of 18.2 months (range 4-40 months), one patient developed local tumor progression at the radiofrequency ablation site. Three patients had new hemangiomas in other sites of the liver. At the end of the study all patients were alive and no severe complications occurred. CONCLUSION Image-guided MWA is an effective and safe treatment for large hepatic hemangiomas, and can potentially be regarded as the first-line therapy.

Comparison of laparoscopic radiofrequency ablation versus open resection in the treatment of symptomatic-enlarging hepatic hemangiomas: a prospective study. Surg Endosc 2015; 30:756-763. [PMID: 26123327 DOI: 10.1007/s00464-015-4274-y] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2015] [Accepted: 04/21/2015] [Indexed: 02/05/2023]
Abstract
BACKGROUND Radiofrequency ablation (RFA) has been demonstrated to be a promising therapy for symptomatic large hepatic hemangioma. However, there is a lack of studies to demonstrate the benefits and disadvantages of RFA as compared with surgical resection for managing hepatic hemangioma. The aim of this study was to evaluate the outcomes of RFA compared with conventional open resection (ORES) for the treatment of symptomatic-enlarging hepatic hemangiomas. METHODS A total of 66 patients with symptomatic-enlarging hepatic hemangiomas (4 cm ≤ diameter < 10 cm) who required surgical treatment were divided into two groups: 32 patients underwent laparoscopic radiofrequency ablation (LRFA) and the other 34 patients underwent ORES. We compared the two groups in terms of radiologic response, clinical response, operative time, estimated blood loss, postoperative pain score and analgesic requirement, length of hospital stay, postoperative complications and hospital cost. RESULTS The radiologic and clinical responses were comparable between groups. LRFA had significantly shorter operative time (138 vs. 201 min, P < 0.001) and less blood loss (P < 0.001) than ORES. Patients after LRFA experienced significantly less pain and required less analgesia use. Moreover, patients underwent LRFA had significantly shorter length of hospital stay (P < 0.001) and lower hospital cost (P = 0.017). No severe morbidities or mortality was observed, and the overall morbidity rate was similar between groups. CONCLUSIONS As a new minimal invasive treatment option, laparoscopic radiofrequency ablation is as safe and effective a procedure as open resection for patients with symptomatic-enlarging hepatic hemangiomas smaller than 10 cm.

Laparoscopic vs computerized tomography-guided radiofrequency ablation for large hepatic hemangiomas abutting the diaphragm. World J Gastroenterol 2015; 21:5941-5949. [PMID: 26019459 PMCID: PMC4438029 DOI: 10.3748/wjg.v21.i19.5941] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2014] [Revised: 01/16/2015] [Accepted: 02/13/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency (RF) ablation vs computed tomography (CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm.
METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma. Altogether, 24 hemangiomas were ablated via a CT-guided percutaneous approach (CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach (laparoscopic ablation group).
RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm (range, 6.0-12.0 cm). There was no difference in the diameter of hemangiomas between the two groups (P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups (P > 0.05). There were 23 thoracic complications in 17 patients: 15 (62.5%, 15/24) in the CT-guided ablation group and 2 (7.4%, 2/27) in the laparoscopic ablation group (P < 0.05). According to the Dindo-Clavien classification, two complications (pleural effusion and diaphragmatic rupture grade III) were major in two patients. All others were minor (grade I). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7% (22/24) and 96.3% (26/27) in the CT-guided and the laparoscopic ablation groups, respectively (P > 0.05).
CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm. It avoids thermal injury to the diaphragm and reduces thoracic complications.

Abstract
BACKGROUND Laparoscopic hepatectomy (LH) using many different surgical techniques has become increasingly popular for the management of hepatic tumors. The performance of surgical procedures involving the least possible impairment is expected increasingly more often by both surgeons and patients. We herein describe a clinical cohort of ten patients with hepatic cavernous hemangioma (HCH) who underwent modified LH (MLH) with a new technique. We herein present the advantages of the low level of impairment during performance of this modified procedure and compare the outcomes of MLH with those of traditional LH (TLH) for HCH. METHODS We retrospectively evaluated the treatment outcomes in 24 patients with HCH who underwent MLH (n = 10) or TLH (n = 14) from February 2008 to January 2013. Their demographic, intraoperative, and postoperative variables were compared. RESULTS MLH was successful in all patients. An electromechanical morcellator allowed for easy extraction of the entire HCH without the use of a cumbersome retrieval bag, enlarged incision, or hand-assisted incision. There was no conversion to an open operation or significant perioperative complications. The operation time (P = 0.037), time to removal of the HCH (P < 0.0001), visual analog scale pain score on the first postoperative day (P = 0.012), time to off-bed activity (P = 0.036), and postoperative hospital stay (P = 0.048) were significantly lower in the MLH group than in the TLH group. CONCLUSIONS MLH involving the use of an electromechanical morcellator provides expedient recovery and minimal postoperative pain and scarring. It is a feasible, effective, and safe surgical procedure and embodies all of the benefits of minimally invasive surgery for patients with HCH.

Abstract
PURPOSE This study was designed to explore the safety and efficacy of percutaneous microwave (MW) ablation as an alternative treatment for symptomatic giant hepatic hemangiomas. METHODS Patients (n = 7; 6 females, 1 male; mean age = 44 years) with symptomatic, giant hemangiomas (n = 8) were treated with ultrasound-guided percutaneous MW ablation and followed for a mean of 18 months. Patient pain was recorded both before and after the procedure according to the 10-point visual analog scale. All patients were treated using one or three gas-cooled 17-gauge antennas powered by a 2.4-GHz generator (Neuwave Medical, Madison, WI). Mean ablation time was 11.6 min. Four patients received hydrodissection to protect the abdominal wall, colon, or gallbladder (5 % dextrose in water, mean volume 900 mL). Immediate postablation biphasic CT of the abdomen was performed, and four of seven patients have undergone delayed follow-up imaging. RESULTS All ablations were technically successful with no major or minor complications. Average pain score decreased from 4.6 to 0.9 (p < 0.05), and six of seven patients report resolution or improvement of symptoms at 18-month average follow-up (range 1-33 months). Immediately postablation, mean tumor diameter decreased 25 % (from 7.3 to 5.5 cm, p < 0.05) and volume decreased 62 % (from 301 to 113 cm(3), p < 0.05). DISCUSSION In this series, percutaneous MW ablation was safe, well-tolerated, and effective in markedly shrinking large hepatic hemangiomas and improving symptoms in most patients.

Abstract
Liver hemangiomas are the most common benign liver tumors and are usually incidental findings. Liver hemangiomas are readily demonstrated by abdominal ultrasonography, computed tomography or magnetic resonance imaging. Giant liver hemangiomas are defined by a diameter larger than 5 cm. In patients with a giant liver hemangioma, observation is justified in the absence of symptoms. Surgical resection is indicated in patients with abdominal (mechanical) complaints or complications, or when diagnosis remains inconclusive. Enucleation is the preferred surgical method, according to existing literature and our own experience. Spontaneous or traumatic rupture of a giant hepatic hemangioma is rare, however, the mortality rate is high (36-39%). An uncommon complication of a giant hemangioma is disseminated intravascular coagulation (Kasabach-Merritt syndrome); intervention is then required. Herein, the authors provide a literature update of the current evidence concerning the management of giant hepatic hemangiomas. In addition, the authors assessed treatment strategies and outcomes in a series of patients with giant liver hemangiomas managed in our department.

Abstract
The presented cases detail percutaneous radiofrequency (RF) ablation of multiple giant hepatic hemangiomas in two patients who presented with right upper-quadrant pain and fullness and chose not to undergo surgical resection. Treatment of two hemangiomas per patient, 7 cm and 6 cm in one and 9 cm and 2 cm in the other, was accomplished in single ablation sessions with 12 and nine cycles, respectively. Patients had durable resolution of symptoms with reduction of lesion size by 68%-82% at a mean follow-up of 13 months. These cases, along with promising results in the current literature, support RF ablation as a safe and effective surgical alternative.

Abstract
AIM To describe initial clinical experience with bipolar radiofrequency ablation (RFA) for symptomatic giant hepatic haemangiomas. MATERIALS AND METHODS Four consecutive patients with a large-volume, symptomatic hepatic cavernous haemangioma of >10 cm were treated with bipolar RFA during laparotomy with ultrasound guidance. Complications were carefully noted. Clinical and radiological effectiveness were evaluated comparing baseline with 3 and 6 months follow-up of symptom assessments and upper abdominal magnetic resonance imaging (MRI) or computed tomography (CT). RESULTS RFA was successfully performed for all four giant haemangiomas. No major complications were observed. Peri-procedural shrinking was remarkable and intermediate-term volume reduction ranged from 58-92% after 6 months. Symptom relief after 6 months was complete in two patients and considerable in the other two. CONCLUSION Preliminary results suggest intra-operative bipolar RFA to be a safe, feasible, and effective technique for treatment of giant symptomatic hepatic cavernous haemangiomas.

Abstract
OBJECTIVE We aimed to assess the feasibility, safety, and efficacy of radiofrequency (RF) ablation for the treatment of large (≥5 cm in greatest diameter) hepatic hemangiomas. METHODS Thirty-six patients (15 male, 21 female; mean age 50 years) with 41 hepatic hemangiomas ≥5 cm in diameter were enrolled and treated with RF ablation attributable to the presence of enlargement tendency and/or persistent hemangioma-associated symptoms. Twenty patients had 24 hemangiomas <10 cm, and 16 patients had 17 hemangiomas ≥10 cm. Technical success, complications related to RF ablation, completed ablation, symptom relief, change in size of ablation zone, and recurrence of the residual tumor were analyzed. RESULTS Of the 41 hemangiomas with a mean diameter 10 ± 4 cm (range, 5-22 cm), 26 subcapsular lesions were treated with a laparoscopic approach, and 15 lesions located in liver parenchyma underwent a computed tomography-guided percutaneous approach. RF ablation was performed successfully in all patients. There were 62 complications related to the ablation in 22 patients, including 6 of 20 patients with hemangiomas <10 cm and all the 16 patients with hemangiomas ≥10 cm. According to the Dindo-Clavien classification, 2 complications (lower esophageal fistula and acute respiratory distress syndrome, Grade III and Grade IV, respectively) were major in 2 patients with hemangiomas ≥10 cm; all the other were minor in 20 patients (Grade I). All the complications were recovered by conservative treatment. Thirty-eight (93%) of 41 hepatic hemangiomas were ablated completely, including all the 24 lesions <10 cm and 14 of 17 lesions ≥10 cm. All the symptoms related to hemangiomas disappeared (n = 22) or were ameliorated (n = 4) after ablation. The mean diameter of ablation zone was decreased to 6 ± 3 cm (2-12 cm) in a mean follow-up period (X ± SD) of 15 ± 6 months (range, 6-24 months), without recurrence or enlargement of the 3 residual tumors. CONCLUSION The present study supports RF ablation as an alternative treatment for hepatic hemangiomas ≥5 cm (but smaller than 10 cm) for the low risk of complications and likelihood of complete ablation, but, in contrast, RF ablation appears to be an inappropriate method for hepatic hemangiomas ≥10 cm because of the high occurrence rate of complications.

Abstract
BACKGROUND & AIMS We aimed to evaluate the feasibility, efficacy, and safety of percutaneous ultrasonography-guided radiofrequency ablation for the management of symptomatic-enlarging hepatic hemangiomas. METHODS Twenty-four patients (5 male and 19 female, with mean age of 49.5±2.2) with 25 hemangiomas over 4 cm underwent percutaneous RFA due to either the presence of symptoms or the enlargement of hemangioma compared with previous imaging studies. RESULTS The mean diameter of hemangioma was 7.2±0.7 cm (4.0-15.0 cm) with 16 hemangiomas in right and 9 hemangiomas in left lobe. Twenty-three hemangiomas (92.0%) were successfully treated by radiofrequency ablation. The mean diameter of hemangiomas was decreased to 4.5±2.4 cm (p<0.001) in serial follow-up CT scans over mean period of 23±3.8 months (23-114 months). Symptoms related to hemangioma disappeared without enlargement of hemangiomas in all successfully treated patients. There were 14 adverse events in 10 patients including abdominal pain, indirect hyperbilirubinemia (>3.0 mg/dl), fever (38.3°C), anemia (<10 g/dl), and ascites, which were successfully managed by conservative treatment. CONCLUSIONS Percutaneous ultrasonography-guided radiofrequency ablation is an effective, minimally invasive, and safe procedure for the management of symptomatic-enlarging hepatic hemangioma.

Abstract
BACKGROUND Control of intraoperative hemorrhage represents a significant challenge in hepatic surgery, particularly during resection of large, hypervascular hepatic hemangiomata (HH). Various devices to minimize blood loss from hepatic parenchymal transection are currently under investigation. Herein, we present our experience with a radiofrequency (RF)-powered multiarray for resection of HH. PATIENTS AND METHODS From September 2005 to January 2006, we conducted a retrospective review of our hepatobiliary database to identify patients with symptomatic giant cavernous HH undergoing resection with a RF multiarray device. The purpose of this review was to assess the technical aspects of using RF energy to assist in the resection of HH. RESULTS The extent of operation varied depending on the size and location of the tumor. Two patients underwent two atypical subsectionectomies and two underwent trisectionectomies. The Habib sealer provided a safe and effective method for hepatic parenchymal transaction. No patients required blood transfusion, and no injuries to major biliary or vascular strictures were observed at 1 year follow-up. A seroma developed in one patient 6 months postoperatively, but was drained percutaneously. CONCLUSIONS Hepatic parenchymal transection with the Habib sealer device is a feasible approach to resect HH. Further study is needed to objectively compare the efficacy of RF-assisted parenchymal transection with that of traditional parenchymal transection techniques.

Abstract
This article reviews the current state of intraoperative ultrasonography in open surgery (IOUS) and laparoscopic surgery (LUS). The review is based on extensive study of data published (Pubmed search) and on 25 years of personal experience with intraoperative ultrasonography. The main application areas of IOUS and LUS and its use during liver, biliary tract, and pancreatic surgery are discussed. The benefits and limitations as well as future expectations with regard to the existing and emerging applications also are discussed. New developments in ultrasound technology and the increasing experience of surgeons in ultrasonography secure the future for IOUS and LUS.

Abstract
Objective In patients that require treatment for hepatic giant cavernous hemangiomas (GCH), radiofrequency ablation (RFA) has been suggested to represent a safe and effective alternative to invasive surgery. In a recent report of bipolar RFA, using two expandable needle electrodes, was uneventfully performed in patients with large GCH (>10 cm). The objective of this report is to present two cases in which bipolar RFA of symptomatic GCH was complicated by acute kidney injury. Materials and methods In 2015 we treated two patients for very large symptomatic GCH (15.7 and 25.0 cm) with bipolar RFA during open laparotomy. Results In both patients the urine showed a red–brown discoloration directly after the ablation. They became anuric and presented with progressive dyspnea, tachypnea, and tachycardia, requiring hemodialysis for a period of 1 month in one case. Lab results revealed hemepigment-induced acute kidney. Both patients fully recovered and both showed a complete relief of symptoms at 3 months following the procedure. Conclusion RFA for large GCHs can cause hemepigment-induced acute kidney injury due to massive intravascular hemolysis. The presented cases suggest that caution is warranted and advocate an upper limit regarding the volume of GCHs that can be safely ablated.
