RESUMEN
BACKGROUND: The role of hepatic resection (HR) combined with radiofrequency ablation (RFA) versus HR alone remains unclear for patients with multifocal hepatocellular carcinomas (HCCs). The aim of this study was to assess the outcomes of selected patients with moderately advanced multifocal HCCs after HR combined with intraoperative RFA versus HR alone. METHODS: A total of 304 selected patients with multifocal HCCs (three or fewer lesions, with the largest lesion > 4.5 cm and the residual lesion[s] ≤ 3 cm) who underwent HR plus RFA (HR+RFA group) or HR alone (HR group) were included. Propensity score matching (PSM) was used to adjust for baseline differences. Multivariable and subgroup analyses estimated the effects of clinical factors on survival. RESULTS: Both overall survival (OS) and recurrence-free survival (RFS) were comparable between both groups before and after PSM. Subgroup analysis showed that HR was associated with better RFS than HR+RFA for those patients with two tumors, or with all lesions located in the same lobe or without microvascular invasion (MVI) [all p < 0.05]. Moreover, en bloc resection provided a higher RFS than separate resection for those with all lesions in the same lobe (p = 0.039). CONCLUSION: For selected patients with moderately advanced multifocal HCCs, HR+RFA may offer similar OS and RFS as HR alone. However, HR may be more suitable for those with two tumors, or with all lesions in the same lobe or without MVI. Moreover, en bloc resection may be recommended for those with all lesions in the same lobe.

BACKGROUND: With the advancement of laparoscopic technology, more precise anatomical hepatectomies such as segmentectomy or even bi-segmentectomy have been recommended by updated expert consensus to treat a single small hepatocellular carcinoma (HCC) [1, 2]. Herein, we presented a video of laparoscopic anatomic bi-segmentectomy (S3 and S4b) using the Glisson's pedicle-first and intrahepatic anatomic markers approach. METHODS: A 66-year-old male was referred for treatment of a single HCC adjacent to the Sagittal part of the left portal vein. The procedure was performed according to the following steps: (1) dissecting and transecting the Glisson's pedicle to S3 and S4b based on Laennec's capsule [3]; (2) identification of the ischemia boundary on the liver surface and confirming the presence of adequate surgical margins within the boundary, ensuing the integrity of segment 2 and 4a by the intraoperative ultrasonography meanwhile; (3) the left parenchymal transection was begun along the demarcation line, exposing the Glisson's pedicle to S2, left hepatic vein, and umbilical fissure vein; (4) the right parenchymal transection was performed to expose the V5, V4b, and V4a. And this operation was approved by the Institutional Review Board of the West China Hospital and written informed consent was obtained from patient of Sichuan University and written informed consent was obtained from patient. (5) The blood supply of residual liver surface was observed, and the integrity of segment 2 and 4a hepatic pedicle was ensured by intraoperative ultrasonography. RESULTS: The operative time was 224 min and blood loss during operation was 50 ml. The histopathologic examination showed a solitary HCC, 4 cm in diameter, with negative surgical margin and no microvascular invasion. The patient had an uneventful postoperative recovery and was discharged on postoperative day 5. CONCLUSION: Laparoscopic bi-segmentectomy (S3 and S4b) using the Glisson's pedicle-first and intrahepatic anatomic markers approach is feasible and effective. Its advantages lie in obtaining the benefits of anatomical hepatectomy, while maximizing the postoperative functional hepatic reserve [4-6].

There are two causes of graft compression in the large-for-size syndrome (LFSS). One is a shortage of intra-abdominal space for the liver graft, and the other is the size discrepancy between the anteroposterior dimensions of the liver graft and the lower right hemithorax of the recipient. The former could be treated using delayed fascial closure or mesh closure, but the latter may only be treated by reduction of the right liver graft to increase space. Given that split liver transplantation has strict requirements regarding donor and recipient selections, reduced-size liver transplantation, in most cases, may be the only solution. However, surgical strategies for the reduction of the right liver graft for adult liver transplantations are relatively unfamiliar. Herein, we introduce a novel strategy of HuaXi-ex vivo right posterior sectionectomy while preserving the right hepatic vein in the graft to prevent LFSS and propose its initial indications.

BACKGROUND: Whether hepatic resection (HR) combined with radiofrequency ablation (RFA) or HR alone is the treatment of choice for early or moderately advanced multifocal hepatocellular carcinomas (HCCs) is a matter of debate. This study compared the short- and long-term outcomes of patients with multifocal tumors meeting the University of California San Francisco (UCSF) criteria after HR plus intraoperative RFA or HR alone. METHODS: A total of 261 consecutive patients with multifocal HCCs meeting the UCSF criteria from January 2010 to January 2018, who underwent combined treatment (n = 51) or HR (n = 210), were included. Propensity score matching was performed to adjust for baseline differences. Overall survival (OS) and recurrence-free survival (RFS) were calculated, and subgroup analysis, along with univariate and multivariate analyses, were performed. RESULTS: The 1-, 3-, and 5-year OS rates after combined treatment or HR alone were 86.3%, 66.6%, and 34.2%, and 92.8%, 67.1%, and 37%, respectively (p = 0.423); combined treatment provided similar RFS rates as HR at 1, 3, and 5 years (78.4%, 35.8% and 20.9% vs. 82.6%, 50.4% and 24.5%, respectively; p = 0.076). The propensity matching model showed similar results. Subgroup analysis showed that HR was associated with better RFS than HR plus RFA for patients with two tumors or major tumors ≤ 3 cm. Multivariate analysis revealed that portal hypertension and three tumors are independent risk factors. CONCLUSIONS: For multifocal HCC patients meeting the UCSF criteria, combined treatment may offer similar OS and RFS as HR; however, HR may be more suitable than combined treatment for patients with two tumors or major tumors ≤ 3 cm.

This retrospective study was conducted to examine the development and current status of pediatric liver transplantation (LT) in western China. Clinical, demographic, morbidity, and mortality data were collected to analyze. It included 260 consecutive pediatric LTs performed at three centers in western China between January 2000 and May 2019. Kaplan-Meier graft survival rates at 1, 3, 5, and 10 years were 82.1%, 77.2%, 76.6%, and 76.6%, respectively; corresponding patient survival rates were 84.7%, 80.7%, 80.0%, and 80.0%, respectively. More patients underwent living donor liver transplantation (LDLT; n = 188 (73.4%)) than deceased-donor liver transplantation (DDLT; n = 68 (26.6%)). Survival was better after LDLT (91.5%, 86.6%, and 80.6% at 1, 3, and 5 years, respectively) than after DDLT (80.9%, 72.4%, and 63.9%, respectively; P < .05). Biliary atresia was the leading LT indication (n = 141 (55.1%)), followed by metabolic disease (n = 36 (14.1%)), which was associated with the best recipient survival (88.5% at 5 years). The transplant era and graft-to-recipient body weight ratio (GRWR) also significantly predicted overall survival. Survival rates at 5 years were worst in 2000-2005 (54.5%) and best for GRWRs of 0.8%-4% (80.4%). The development of pediatric LT in western China began slowly, but the quantity and quality of pediatric LT has progressed in recent years. This procedure is now a promising and reliable treatment for children with end-stage liver disease in western China.

BACKGROUND: Biliary reconstruction in ex vivo liver resection followed by autotransplantation (ERAT) for end-stage hepatic alveolar echinococcosis (HAE) remains the most challenging step, we present our experience with this complex procedure. METHODS: A retrospective data analysis of 55 patients with end-stage HAE underwent ERAT, the biliary reconstruction techniques and short- and long-term outcomes were discussed. RESULTS: All autografts were derived from the left lateral section after extensive ex vivo liver resection, multiple bile ducts were observed in 52 (94.5%) patients, and forty-four (80.0%) cases required ductoplasty. Biliary reconstruction was achieved with duct-to-duct anastomosis in 32 (58.2%) patients, Roux-en-Y hepaticojejunostomy (RYHJ) in 14 (25.5%) patients, and a combination of the two methods in 9 (16.4%) patients. Twenty (36.4%) patients had multiple anastomoses. Biliary leakage occurred in 8 (14.5%) patients postoperatively. Three (5.5%) patients died of liver failure, cerebral hemorrhage and intraabdominal bleeding. During a median of 31 months followed-up time, 3 (5.5%) patients developed anastomotic stricture, 1 of whom was treated by repeat RYHJ, while the others were managed with stenting. CONCLUSIONS: With a well-designed plan and precise anastomosis, complex biliary reconstruction in ERAT can be performed with few biliary complications by a professional team.

Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end-stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This article aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality. The median weight of the autografts was 636 g (360-1300 g), the median operation time was 12.5 hours (9.4-19.5 hours), and the median anhepatic phase was 309 minutes (180- 460 minutes). Intraoperative blood loss averaged 1800 mL (1200-6000 mL). Postoperative complications occurred in 13 patients during hospitalization; 5 patients experienced postoperative complications classified as Clavien-Dindo grade III or higher, and 2 patients died of intraabdominal bleeding and acute cerebral hemorrhage, respectively. Twenty-nine patients were followed for a median of 14.0 months (3-42 months), and no HAE recurrence was detected. The technique requires neither an organ donor nor any postoperative immunosuppressant, and the success of the treatment relies on meticulous preoperative assessments and precise surgical manipulation.

Many noninvasive methods for diagnosing liver fibrosis (LF) have been proposed. To determine the best method for diagnosing LF in nonalcoholic fatty liver disease (NAFLD), we conducted a systemic review and meta-analysis to compare the performance of aspartate aminotransferase to platelets ratio index (APRI), fibrosis-4 index (FIB-4), BARD score, NAFLD fibrosis score (NFS), FibroScan, shear wave elastography (SWE), and magnetic resonance elastography (MRE) for diagnosing LF in NAFLD. We compared the sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUROC) of these noninvasive methods for detecting significant fibrosis (SF), advanced fibrosis (AF), and cirrhosis. Heterogeneity was explored using meta-regression. Sixty-four articles with a total of 13,046 NAFLD subjects were included. The overall mean prevalence of SF, AF, and cirrhosis was 45.0%, 24.0%, and 9.4% in NAFLD patients, respectively. With an APRI threshold of 1.0 and 1.5, the sensitivities and specificities were 50.0% and 84.0% and 18.3% and 96.1%, respectively, for AF. With a FIB-4 threshold of 2.67 and 3.25, the sensitivities and specificities were 26.6% and 96.5% and 31.8% and 96.0%, respectively, for AF. The summary sensitivities and specificities of BARD score (threshold of 2), NFS (threshold of -1.455), FibroScan M (threshold of 8.7-9), SWE, and MRE for detecting AF were 0.76 and 0.61, 0.72 and 0.70, 0.87 and 0.79, 0.90 and 0.93, and 0.84 and 0.90, respectively. The summary AUROC values using APRI, FIB-4, BARD score, NFS, FibroScan M probe, XL probe, SWE, and MRE for diagnosing AF were 0.77, 0.84, 0.76, 0.84, 0.88, 0.85, 0.95, and 0.96, respectively. CONCLUSION: MRE and SWE may have the highest diagnostic accuracy for staging fibrosis in NAFLD patients. Among the four noninvasive simple indexes, NFS and FIB-4 probably offer the best diagnostic performance for detecting AF. (Hepatology 2017;66:1486-1501).

BACKGROUND: There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). METHODS: A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. RESULTS: During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5-39.5), 16.0 (95% CI 12.2-19.7) and 6.0 (95% CI 4.8-7.2) months, respectively (P < 0.001). CONCLUSIONS: The dNLR-PNI can predict the survival outcomes of intermediate-to-advanced HCC patients undergoing TACE, and should be further evaluated as a prognostic marker for who are to undergo TACE treatment.

BACKGROUND: The treatment of intrahepatic recurrent hepatocellular carcinoma (HCC) has been poorly investigated, and the optimal treatment strategy remains unclear. AIMS: The aim of this study was to compare outcomes between salvage liver transplantation (SLT) and re-resection (RR)/radiofrequency ablation (RFA) for intrahepatic recurrent HCC according to recurrence pattern. METHODS: Based on postoperative histopathological examination, 122 patients with intrahepatic recurrent HCC were divided into an intrahepatic metastasis (IM, n = 75) group and a multicentric occurrence (MO, n = 47) group. The demographic, clinical, and primary and recurrent tumor characteristics of the IM group and the MO group were collected and compared. Overall survival (OS) and disease-free survival (DFS) were analyzed, and subgroup analysis according to retreatment type (SLT vs. RR/RFA) was conducted. Twenty-nine clinicopathological variables potentially related to prognostic factors affecting survival were analyzed using a Cox proportional hazard model. RESULTS: The patients that received SLT treatment exhibited favorable DFS compared to patients that received RR/RFA (P = 0.002). OS (P < 0.001) and DFS (P = 0.008) rates were significantly increased in the MO group compared with in the IM group. Subgroup analysis revealed that DFS was significantly improved for patients in the MO group treated with SLT compared to patients treated with RR/RFA (P = 0.017). Recurrence pattern was an independent prognostic factor for both OS [hazard ratio (HR) = 0.093, 95% confidence interval (CI): 0.026-0.337, P < 0.001] and DFS (HR = 0.318, 95% CI: 0.125-0.810, P = 0.016; HR = 3.334, 95% CI: 1.546-7.18, P = 0.002). CONCLUSIONS: For patients with intrahepatic recurrent HCC, an MO recurrence pattern is associated with better long-term outcomes than the IM pattern. SLT is the preferred option for intrahepatic recurrent HCC, especially for MO cases.

BACKGROUND: The adoption of laparoscopic techniques for living donor major hepatectomy has been controversial issue. The aim of this study is to present the preliminary experience of laparoscopic right hepatectomy in China. METHODS: All the donors receiving right hepatectomy for adult-to-adult living donor liver transplantation (LDLT) were divided into three groups: pure laparoscopic right hepatectomy (PLRH) group, hand-assisted right hepatectomy (HARH) group and open right hepatectomy (ORH) group. We compared the perioperative data and surgical outcomes of donors and recipients among three groups. RESULTS: From November 2001 to May 2017, 295 donors have received right hepatectomy for LDLT in our center. Among them, 7 donors received PLRH, 26 donors received HARH and 262 donors received ORH. The operation time of PLRH group (509.3 ± 98.9 min) was longer than that of the HARH group (451.6 ± 89.7 min) and the ORH group (418.4 ± 81.1 min, p = 0.003). The blood loss was the least in the PLRH group (378.6 ± 177.1 mL), compared with that in the HARH group (617.3 ± 240.4 mL) and that in the ORH group (798.6 ± 483.7 mL, p = 0.0013). The postoperative hospital stay was shorter in the PLRH group (7, 7-10 days) than that in the HATH group (8.5, 7.5-12 days) and ORH group (11, 9-14 days; p = 0.001). Only one donor had pleural effusion (Grade I) and another one experienced pulmonary infection (Grade II). One recipient (14.3%) in the PLRH group occurred hepatic venous stenosis. CONCLUSIONS: Laparoscopic approaches for right hepatectomy contribute to less blood loss, better cosmetic satisfaction, less severe complications, and faster rehabilitation. PLRH is a safe and feasible procedure, which must be performed in highly specialized centers with expertise of both LDLT and laparoscopic hepatectomy, and requires a hybrid-to-pure stepwise development.

OBJECTIVE: Albumin-bilirubin (ALBI) grade has been validated as a simple, evidence-based, and objective prognostic tool for patients with hepatocellular carcinoma (HCC). However, minimal information is available concerning postoperative ALBI grade changes in HCC. This study aimed to investigate the prognostic value of postoperative ALBI grade changes in patients with hepatitis B virus (HBV)-related HCC within the Milan criteria after liver resection. METHODS: Patients with HBV-related HCC within the Milan criteria who underwent liver resection between 2010 and 2016 at West China Hospital were reviewed (N = 258). A change in ALBI grade was defined as first postoperative month ALBI grade-preoperative ALBI grade. If the value was >0, postoperative worsening of ALBI grade was considered; otherwise, stable ALBI grade was considered. Cox proportional hazard regression analyses were used to determine the factors that influence recurrence and survival. RESULTS: During the follow-up, 130 patients experienced recurrence and 47 patients died. Multivariate analyses revealed that postoperative worsening of ALBI grade (HR 1.541, 95% CI 1.025-2.318, P = 0.038), microvascular invasion (MVI, HR 1.802, 95% CI 1.205-2.695, P = 0.004), and multiple tumors (HR 1.676, 95% CI 1.075-2.615, P = 0.023) were associated with postoperative recurrence, whereas MVI (HR 2.737, 95% CI 1.475-5.080, P = 0.001), postoperative worsening of ALBI grade (HR 2.268, 95% CI 1.227-4.189, P = 0.009), high alpha-fetoprotein level (HR 2.055, 95% CI 1.136-3.716, P = 0.017), and transfusion (HR 2.597, 95% CI 1.395-4.834, P = 0.003) negatively influenced long-term survival. Patients with postoperative worsening of ALBI grade exhibited increased incidence of recurrence and worse long-term survival. CONCLUSION: Postoperative worsening of ALBI grade was associated with increased recurrence and poorer overall survival for patients with HBV-related HCC within the Milan criteria. We should pay attention to liver function changes in HCC patients after liver resection.

OBJECTIVE: To investigate the postoperative hemodynamics changes and their influence factors in the donors after right lobe living donor liver transplantation. METHODS: A total of 53 consecutive living donors from Dec 2010 to Aug 2015 who underwent donor right lobe hepatectomy were retrospectively analyzed. We measured residual liver hemodynamics with color doppler ultrasound, detected liver stiffness by transient elastography, also analyzed postoperative liver function, hemodynamics, and the long term variation tendency of hepatocirrhosis and spleen. RESULTS: One week after operation, transient liver damage was observed. Post-operative hemodynamics within the follow-up time showed:portal vein diameter was gradually increasing, the velocity decreased gradually;Hepatic vein diameter increased, and the velocity decreased gradually. There was a negative correlation between portal vein diameter and portal vein velocity (P=0.012, r=-3.11). Liver stiffness (Kpa value) decreased gradually with time, while spleen volume gradually increased. Correlation analysis showed that postoperative liver stiffness (Kpa value) was negatively related to portal vein diameter (P=0.013, r=-0.338) and positively related to hepatic venous velocity (P=0.038,r=0.246). CONCLUSIONS: The donor presented a transient liver injury after operation, but tended to be recovery after one week. Despite post-operative hemodynamic undergo a series of changes, but it does not affect the post-operative long-term donor safety.
RESUMEN
BACKGROUND: Many studies have confirmed that serum total cholesterol (sTC) concentrations were associated with underlying liver damage and the synthesis capacity of liver. However, the role of postoperative sTC level on evaluating graft function and predicting survival of recipients who underwent liver transplantation has not been discussed. METHODS: Clinical data of 231 living donor liver transplantation recipients from May 2003 to January 2015 were retrospectively collected. Patients were stratified into the low sTC group (sTC <1.42 mmol/L, 57 recipients) and high sTC group (sTC =1.42 mmol/L, 174 recipients) according the sTC level on postoperative day 3 based on receiver-operating characteristic curve analysis. The clinical characteristics and postoperative short- and long-term outcomes were compared between the two groups. RESULTS: Recipients with sTC <1.42 mmol/L experienced more severe preoperative disease conditions, a higher incidence of postoperative early allograft dysfunction (38.6% vs 10.3%, P<0.001), 90-day mortality (28.1% vs 10.9%, P=0.002) and severe complications (29.8% vs 17.2%, P=0.041) compared to recipients with sTC =1.42 mmol/L. The multivariate analysis demonstrated that sTC <1.42 mmol/L had a 4.08-fold (95% CI: 1.83-9.11, P=0.001) and 2.72-fold (95% CI: 1.23-6.00, P=0.013) greater risk of developing allograft dysfunction and 90-day mortality, and patients with sTC <1.42 mmol/L had poorer overall recipient and graft survival rates at 1-, 3-, and 5-year than those with sTC =1.42 mmol/L (67%, 61% and 61% vs 83%, 71% and 69%, P=0.025; 65%, 59% and 59% vs 81%, 68% and 66%, P=0.026, respectively). Cox multivariate analysis showed that sTC <1.42 mmol/L was an independent predicting factor for total recipient survival (HR=2.043; 95% CI: 1.173-3.560; P=0.012) and graft survival (HR=1.905; 95% CI: 1.115-3.255; P=0.018). CONCLUSIONS: sTC <1.42 mmol/L on postoperative day 3 was an independent risk factor of postoperative early allograft dysfunction, 90-day mortality, recipient and graft survival, which can be used as a marker for predicting postoperative short- and long-term outcomes.

UNLABELLED: The aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis index based on the four factors (Fibrosis 4 index; FIB-4) are the two most widely studied noninvasive tools for assessing liver fibrosis. Our aims were to systematically review the performance of APRI and FIB-4 in hepatitis B virus (HBV) infection in adult patients and compare their advantages and disadvantages. We examined the diagnostic accuracy of APRI and FIB-4 for significant fibrosis, advanced fibrosis, and cirrhosis based on their sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUROC). Heterogeneity was explored using metaregression. Our systemic review and meta-analysis included 16 articles of APRI only, 21 articles of APRI and FIB-4 and two articles of FIB-4 for detecting different levels of liver fibrosis. With an APRI threshold of 0.5, 1.0, and 1.5, the sensitivity and specificity values were 70.0% and 60.0%, 50.0% and 83.0%, and 36.9% and 92.5% for significant fibrosis, advanced fibrosis, and cirrhosis, respectively. With an FIB-4 threshold of 1.45 and 3.25, the sensitivity and specificity values were 65.4% and 73.6% and 16.2% and 95.2% for significant fibrosis. The summary AUROC values using APRI and FIB-4 for the diagnosis of significant fibrosis, advanced fibrosis, and cirrhosis were 0.7407 (95% confidence interval [CI]: 0.7033-0.7781) and 0.7844 (95% CI: 0.7450-0.8238; (Z = 1.59, P = 0.06), 0.7347 (95% CI: 0.6790-0.7904) and 0.8165 (95% CI: 0.7707-0.8623; Z = 2.01, P = 0.02), and 0.7268 (95% CI: 0.6578-0.7958) and 0.8448 (95% CI: 0.7742-0.9154; (Z = 2.34, P = 0.01), respectively. CONCLUSIONS: Our meta-analysis suggests that APRI and FIB-4 can identify hepatitis B-related fibrosis with a moderate sensitivity and accuracy.

UNLABELLED: Current guidelines recommend surgical resection as the primary treatment for a single hepatocellular cancer (HCC) with Child's A cirrhosis, normal serum bilirubin, and no clinically significant portal hypertension. We determined how frequently guidelines were followed and whether straying from them impacted survival. BRIDGE is a multiregional cohort study including HCC patients diagnosed between January 1, 2005 and June 30, 2011. A total of 8,656 patients from 20 sites were classified into four groups: (A) 718 ideal resection candidates who were resected; (B) 144 ideal resection candidates who were not resected; (C) 1,624 nonideal resection candidates who were resected; and (D) 6,170 nonideal resection candidates who were not resected. Median follow-up was 27 months. Log-rank and Cox's regression analyses were conducted to determine differences between groups and variables associated with survival. Multivariate analysis of all ideal candidates for resection (A+B) revealed a higher risk of mortality with treatments other than resection. For all resected patients (A+C), portal hypertension and bilirubin >1 mg/dL were not associated with mortality. For all patients who were not ideal candidates for resection (C+D), resection was associated with better survival, compared to embolization and "other" treatments, but was inferior to ablation and transplantation. CONCLUSIONS: The majority of patients undergoing resection would not be considered ideal candidates based on current guidelines. Not resecting ideal candidates was associated with higher mortality. The study suggests that selection criteria for resection may be modestly expanded without compromising outcomes, and that some nonideal candidates may still potentially benefit from resection over other treatment modalities.

BACKGROUND: Radiofrequency ablation (RFA) is a radical treatment for both primary and recurrent small hepatocellular carcinoma (HCC) with an optimistic outcome which is comparable with surgery. For localized recurrence of HCC after liver transplantation (LTx), surgical resection is considered the most favorable treatment. When surgical resection is contraindicated or technically infeasible, whether RFA is as efficient after transplantation as in nontransplant settings remains unclear. MATERIALS AND METHODS: A cohort study was undertaken in a population of patients that had a recurrence of HCC after LTx to evaluate the outcomes of different modalities (surgery, RFA, and conservative therapy) on long-term survival. RESULTS: Seventy-eight of the 486 HCC patients who received LTx had a recurrence (16%). Fifteen patients underwent surgical resection, and 11 patients were treated with RFA. The remaining 52 patients received conservative therapy (17 patients with sirolimus plus sorafenib regimen; the others were treated with conventional supportive therapy). The 1-, 3-, and 5-y overall survival rates were 92%, 51%, and 35% for the patients treated with surgery and 87%, 51%, and 28% for the patients that received RFA. The corresponding 1-, 3-, and 5-y rerecurrence-free survival rates were 83%, 16%, and 16% for the patients treated with surgery and 76%, 22%, and 0% for the patients that received RFA, respectively. There was no significant difference in overall survival or rerecurrence-free survival between the surgical resection group and the RFA group (P = 0.879, P = 0.745). CONCLUSIONS: For HCC recurrence after LTx, RFA is preferable when surgical resection is contraindicated or technically infeasible and provides comparable long-term survival compared with surgery.

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.
