ABSTRACT

With the development and maturity of liver transplant techniques, liver transplantation has become one of the vital treatment options for hepatocellular carcinoma (HCC). Postoperative recurrence and metastasis of HCC after liver transplantation is one of critical factors that affect the long-term survival of recipients. Exploring the prevention and therapeutic strategies for HCC recurrence and metastasis after liver transplantation plays a pivotal role in improving the clinical efficacy of liver transplantation for HCC recipients. Intimate monitoring, active prevention, early diagnosis, comprehensive surgical treatment and local treatment, especially targeted immunotherapy, and individualized prevention and therapeutic strategies are of significance for the prevention and treatment of HCC recurrence and metastasis after liver transplantation. In this article, the monitoring, diagnosis, prevention and treatment of tumor recurrence and metastasis after liver transplantation for HCC were reviewed, aiming to provide reference for the prevention and treatment of tumor recurrence and metastasis after liver transplantation, enhancing clinical efficacy of liver transplantation and prolonging the survival of recipients.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. At present, hepatectomy is one of the most frequent therapeutic options, whereas the high postoperative recurrence rate severely affects the long-term survival of HCC patients. Therefore, it is urgent to choose appropriate therapeutic regime to treat the recurrence of HCC to improve the long-term survival of HCC patients. Surgical treatment is an efficacious treatment for recurrent HCC, including re-hepatectomy, salvage liver transplantation and radiofrequency ablation. Currently, individualized treatment is recommended for postoperative recurrence of HCC. The selection of treatment should be conducted based on the tumor conditions after the first hepatectomy, the characteristics of recurrent tumors, baseline data of patients and recurrence time, etc., aiming to formulate appropriate treatment regimes for patients. In this article, these surgical regimes were reviewed and compared to explore appropriate surgical schemes for postoperative recurrence of HCC, aiming to provide reference for prolonging the survival of HCC patients.

ABSTRACT

ABSTRACT Objective: The objective of this study is to compare the total costs of surgery and radiofrequency (RF) ablation for the treatment of benign thyroid nodules. Materials and methods: This is a prospective randomized study comparing cases treated with US-guided RF ablation (cases) and surgery (control). They were selected and allocated to groups (thyroidectomy or radioablation) by permuted block randomization in blocks of five cases each. Results: Five cases of RF Ablation were compared with five cases of thyroidectomies conducted in the same period. Similar complication rates were observed in both groups. Shorter operating time and hospital stay were observed for the RF group. In the evaluation of the total cost between procedures, radioblation represented 76% of the cost of partial thyroidectomy. Conclusion: This study demonstrated that radioablation has a competitive cost, making it an effective alternative in the treatment of benign thyroid nodules.

ABSTRACT

Background:Lumbar sympathectomy through radio ablation is a useful treatment of peripheral ischemia. However, clinical efficacy with respect to lower limb ulcers is not adequately established in the Indian population. The study was conducted to evaluate the role of radiofrequency ablation (RFA) of the lumbar sympathetic ganglia in healing of ischemic ulcers of the lower limb.Method:The prospective study with 63 patients registered in the General surgery department with lower limb ischemic ulcers between December 2017­ July2019 were treated with RFA. Patients with cardiopulmonary disease, pregnant, congenital malformation, or skin infection at the site of intervention, or suffering from bleeding disorders, were excluded from the study. Clinical investigation of the wound was performed, and demographic data was collected. Comparative reduction in wound size was assessed through Friedman`s ANOVA (P<0.001). Difference in pain score, hospital stay, and walking distance were evaluated using Wilcoxon matched pair test (P<0.001), Unpaired t-test, and Paired t-test (P<0.05).Result:Majority of the patients were male (n=40) with a mean age of 60.93 SD14.34 years. Significant reduction in wound size, pain scores and hospital stay were observed post procedure(P<0.001). Number of RFA sessions was significantly associated with the size of the ulcer and Fontaine's classification 2 and 3 (P<0.0001).Conclusion:RFA of lumbar sympathetic ganglia is a potential treatment modality for lower limb ischemic ulcers.


Antecedentes: La simpatectomía lumbar a través de la ablación por radiofrecuencia es un tratamiento útil de la isquemia periférica. Sin embargo, la eficacia clínica con respecto a las úlceras en las extremidades inferiores no está adecuadamente establecida en la población india. El estudio se llevó a cabo para evaluar el papel de la ablación por radiofrecuencia (RFA) de los ganglios simpáticos lumbares en la curación de las úlceras isquémicas de la extremidad inferior. Método: El estudio prospectivo con 63 pacientes registrados en el departamento de cirugía general con úlceras isquémicas de las extremidades inferiores entre diciembre de 2017 y julio de 2019 fueron tratados con RFA. Los pacientes con enfermedad cardiopulmonar, malformación embarazada, congénita o infección de la piel en el lugar de la intervención, o que sufren de trastornos hemorrágicos, fueron excluidos del estudio. Se realizó una investigación clínica de la herida y se recopilaron datos demográficos. La reducción comparativa en el tamaño de la herida se evaluó a través del ANOVA de Friedman (P<0.001).Resultado: La diferencia en la puntuación del dolor, la estancia en el hospital y la distancia a pie se evaluaron mediante la prueba de par coincidente de Wilcoxon (P<0.001), la prueba t no emparejada y la prueba t emparejada (P<0.05). La mayoría de los pacientes eran varones (n-40) con una edad media de 60,93 SD14,34 años. Se observó una reducción significativa en el tamaño de la herida, las puntuaciones de dolor y la estancia hospitalaria (P<0.001). El número de sesiones de RFA se asoció significativamente con el tamaño de la úlcera y las clasificaciones 2 y 3 de Fontaine (P<0.0001).Conclusión: LA RFA de los ganglios simpáticos lumbares puede constituir una opción terapéutica para las úlceras isquémicas de las extremidades inferiores.

ABSTRACT

BACKGROUND@#With the wide application of computed tomography (CT) in the screening of early lung cancer, more and more ground glass nodules (GGNs) have been found. Early intervention is helpful to improve the survival rate of lung cancer patients. Radiofrequency ablation (RFA) is an alternative option to manage primary or metastatic lung malignancies. The purpose of this study is to review the safety and clinical efficacy for lung GGN treated by RFA.@*METHODS@#From June 2016 to March 2021, 24 patients with a total of 28 lung GGNs in our hospital underwent 28 sessions of RFA. There were 13 males and 11 females with an average age of (69.4±11.1) years. The size of GGN receiving RFA was (1.30±0.56) cm; The ablation range was (2.50±0.63) cm and ablation time was (15.00±8.68) min.@*RESULTS@#The procedure of all RFAs went smoothly, no perioperative deaths occurred and no serious complications during the operation. The median follow-up was 25 months. One case died of myocardial infarction 2 months after operation. All 28 GGNs showed no evidence of local progression and the local control rate was 100.0%. Kaplan-Meier analysis showed that the 1-year and 2-year overall survival rates were 95.8% and 95.8%; the tumor specific survival rates were 100.0% and 100.0%, respectively.@*CONCLUSIONS@#RFA is a safe, effective and minimally invasive technique for the treatment of lung GGNs.

ABSTRACT

Objective:To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome. Conclusion:Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.

ABSTRACT

Objective:To study the predictive value of superb microvascular imaging(SMI) in evaluating therapeutic efficacy of hepatic cancer treated by percutaneous radiofrequency ablation(PRFA).Methods:From Feb 2017 to Feb 2018, 55 patients (male: 31, female: 24, age range: 37-68 years, mean age: 56years) with 72 hepatic carcinoma lesions (length: 21.3-45.6 mm, average: 31.2 mm) were detected by SMI and contrast-enhanced CT(CECT)before PRFA. One month after treatment, more than two imaging examinations (CECT, CEMR, ultrasonic imaging) were used as the "gold standard" to evaluate the complete ablation rates. Consistency between the SMI grading and the arterial phase enhancement of CECT was analyzed by the Kappa-test.Results:Before PRFA, SMI showed 12 lesions (16.7%) to be in grade Ⅰ, 28 lesions (38.9%) in grade Ⅱ and 32 lesions (44.4%) in grade Ⅲ. The arterial phase of CECT showed 37 lesions (51.4%) to have no obvious enhancement and 35 lesions (48.6%) to have obvious enhancement. Consistency analysis showed that there was a high consistency between SMI and CECT(Kappa=0.861, P<0.001). The higher the SMI grading, the more obvious the enhancement on CECT. The complete ablation rates of the grade Ⅰ, grade Ⅱ and grade Ⅲ lesions were 100%(12/12), 92.9%(26/28) and 71.9%(23/32), respectively. The complete ablation rate of the lesions in grade Ⅲ was significantly lower than that in grade Ⅰ and grade Ⅱ (both P<0.05). Conclusion:SMI showed a good consistency with CECT in evaluating the blood flow signals of hepatic cancer, SMI grading could be used in predicting the therapeutic efficacy of hepatic cancer treated by PRFA.

ABSTRACT

Objective:To analyze the feasibility and efficacy of ultrasound-guided percutaneous biopsy and radiofrequency ablation of gallbladder polyps.Methods:From April 2019 to January 2021, 25 patients with gallbladder polyps underwent ultrasound-guided biopsy and radiofrequency ablation in the ultrasound department of the First Affiliated Hospital of Zhengzhou University were collected, the maximum diameter of the lesion was 11.00(10.00, 12.50)mm. Under general anesthesia, ultrasound-guided injection of water into the gallbladder serosa layer was performed to make the gallbladder edema thicker than or equal to 10 mm. Percutaneous biopsy and radiofrequency ablation of gallbladder polyps were performed to ablate the gallbladder mucosa layer of polyps and polyp attachment.Intraoperative contrast-enhanced ultrasound was used to evaluate the need for supplementary ablation.The operation time, intraoperative and postoperative conditions were recorded. The complete ablation rate of gallbladder polyps, the reduction rate of lesion volume after ablation, the incidence of complications and the effect of operation on gallbladder wall thickness and gallbladder contraction rate were evaluated.Results:Biopsy and radiofrequency ablation of gallbladder polyps were successfully performed in 25 patients.There were 14 cases of cholesterol polyp, 5 cases of adenoma, 5 cases of inflammatory polyp and 1 case of gallbladder adenomyosis. Twenty-nine gallbladder polyps showed changes after ablation, and the lesion volume was reduced to varying degrees. In the first, third and sixth months, the volume reduction rates of ablation focus were 70.74%(58.55%, 77.56%), 89.47%(85.04%, 96.87%) and 100%(95.68%, 100%) respectively, and the differences were statistically significant ( P<0.05). There were no significant differences in gallbladder wall thickness and gallbladder contraction rate before and 1 month after operation ( P>0.05). The operation time was 14-39(23.32±6.68)min. During the operation, 3 patients(12.0%) had a decrease in heart rate, 2 patients(8.0%) had mild abdominal pain and 1 patient(4.0%) had obvious abdominal pain, which was relieved after treatment. No bleeding, gallbladder perforation, abdominal infection and other complications occurred. All patients were followed up for 1 to 22 months, with a median of 6 (3, 7) months. No patients were lost or follow-up, polyp recurrence, or new polyps, or secondary gallstone. Conclusions:Ultrasound-guided biopsy and radiofrequency ablation of gallbladder polyps is a feasible choice for gallbladder preserving treatment of gallbladder polyps with low complication rate.

ABSTRACT

Objective To analyze the clinical efficacy of different anti-tumor therapies for recurrence and metastasis after liver transplantation for primary liver cancer (liver cancer). Methods Clinical data of 145 recipients undergoing liver transplantation for liver cancer were retrospectively analyzed. The overall survival and recurrence and metastasis after liver transplantation for liver cancer were analyzed. The clinical efficacy of different anti-tumor therapies for recipients with recurrence and metastasis were compared. Results Sixty-five recipients (44.8%) developed recurrence and metastasis. The median recurrence time was 6 months. Among them, 1 case underwent secondary liver transplantation after recurrence and died of intestinal perforation. Twenty-four recipients (37%) received targeted drug therapy with a median tumor-bearing survival of 22 months. Eleven recipients (17%) received radiotherapy or chemotherapy with a median tumor-bearing survival of 11 months. Nine recipients (14%) received local treatment (surgical resection or radiofrequency ablation), and the median tumor-bearing survival was 8 months. Twenty recipients (31%) abandoned anti-tumor therapy, and the median tumor-bearing survival was 3 months. The tumor-bearing survival of recipients receiving anti-tumor therapy was significantly longer than that of recipients without anti-tumor therapy (P < 0.001). The tumor-bearing survival of recipients receiving targeted drug therapy was significantly longer than that of those receiving other anti-tumor therapies (P=0.03). The tumor-bearing survival of recipients receiving local treatment, radiotherapy and chemotherapy was considerably longer than that of those who abandoned anti-tumor therapy (P=0.004). Conclusions Surgical resection and radiofrequency ablation are the optimal therapies for recipients with recurrence and metastasis after liver transplantation for liver cancer. For recipients with multi-focal tumors who fail to receive local treatment, those receiving targeted drug therapy obtain the longest survival. In addition, radiotherapy and chemotherapy can also prolong the survival of recipients with recurrence and metastasis.

ABSTRACT

ObjectiveTo investigate the safety and efficacy of re-hepatic resection (rHR) versus radiofrequency ablation (RFA) in the treatment of recurrent hepatocellular carcinoma (RHCC) in Asia through a meta-analysis. MethodsPubMed, CNKI, and Wanfang Data were searched for related studies published up to June 15, 2020. Two reviewers independently searched for the articles and extracted related data, and RevMan 5.4.1 was used to perform the meta-analysis. ResultsA total of 2 randomized controlled trials and 18 retrospective cohort studies met the inclusion criteria and involved 2903 patients with RHCC from Asian countries. The mortality rate in the perioperative period was 2% in the rHR group and 0 in the RFA group, and the incidence rate of perioperative complications was 22.4% in the rHR group and 3.3% in the RFA group. The 1-, 3-, and 5-year overall survival rates were 92.3%, 66.3%, and 51.1%, respectively, in the rHR group and 91.4%, 69.2%, and 39.9%, respectively, in the RFA group. The 1-, 3-, and 5-year disease-free survival rates were 67.9%, 48.3%, and 34.4%, respectively, in the rHR group and 57.5%, 27.9%, and 14.0%, respectively, in the RFA group. The Meta-analysis showed that there was no significant difference in overall survival rate between the two groups (hazard ratio [HR]=089, 95% confidence interval [CI]: 0.77-1.02, P=0.10), while the rHR group had a significantly higher disease-free survival rate than the RFA group (HR=0.79, 95% CI: 0.72-0.87, P<0.001). ConclusionCurrent evidence shows that rHR may help to achieve a higher disease-free survival rate than RFA in the treatment of RHCC, while rHR and RFA have a similar overall survival rate.

ABSTRACT

@#Objective    To evaluate the early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation. Methods    The clinical data of 31 patients with atrial fibrillation who underwent total thoracoscopic Box Lesion radiofrequency ablation between November 2011 and March 2018 at the Department of Cardiac Surgery in our hospital were retrospectively analyzed, including 23 males and 8 females at an average age of 66.17±8.32 years. All patients did not have concomitant severe organic heart disease which required surgical intervention. Results    There were 20 patients with paroxysmal atrial fibrillation, 8 with persistent atrial fibrillation, and 3 with long-standing persistent atrial fibrillation. Twenty-nine patients got the 3-year follow-up, and 2 patients were lost to the follow-up 6 months after the surgery. The procedure was successfully performed in all patients, with an average operation time of 113.00±26.00 min. There was no perioperative death or related complication. All patients were restored to sinus rhythm immediately after surgery. Five patients got atrial fibrillation during postoperative hospitalization, which reverted to sinus rhythm after electrical cardioversion. The rate of sinus rhythm maintenance was 62.9%, 55.9% and 52.4%in postoperative 1, 2 and 3 years, respectively. No patient died during the period, and no procedure-related complication was observed. Conclusion    Total thoracoscopic Box Lesion radiofrequency ablation effectively shortens operation time, and reduces surgical trauma and procedure-related complications, meanwhile, ensures the surgical outcomes.

ABSTRACT

@#Objective    To analyze the correlation between the gray value of epicardial fat and the prognosis of patients with atrial fibrillation (AF) treated by thoracoscopic radiofrequency ablation. Methods    The clinical data of 97 patients, including 75 males and 22 females with an average age of 57.8±9.4 years, who underwent thoracoscopic radiofrequency ablation in Fuwai Hospital from 2017 to 2018 were analyzed retrospectively. The left atrial fat volume and average gray scale were calculated by left atrial enhanced CT. According to the average gray scale of left atrial fat tissue, the patients were divided into three groups: a high gray scale group, a medium gray scale group and a low gray scale group. The patients were followed up at 3, 6 and 12 months after operation. The end point of follow-up was the recovery rate of sinus rhythm. Survival analysis was used to analyze the correlation between CT features of epicardial fat enhancement and prognosis. Results    After adjustment of body mass index, body surface area, gender and left atrial end diastolic diameter, regression analysis showed that the fat gray of left atrial enhanced CT was correlated with the type of AF (OR=0.30, 95%CI 0.12-0.79, P=0.014). Cox regression analysis showed that the fat gray value of left atrial CT predicted the recurrence of AF after thoracoscopic radiofrequency ablation (OR=0.92, 95%CI 0.85-0.99). The Kaplan-Meier curve showed significant difference in the long-term recurrence rate of AF among the three groups (P=0.011). The lower left atrial fat enhanced CT gray scale was, the higher long-term recurrence rate of AF was. Conclusion    The gray value of left atrial fat enhanced CT can effectively predict the recurrence of AF after radiofrequency ablation in thoracoscopic surgery.

ABSTRACT

OBJECTIVES: To investigate whether quantitative textural features, extracted from pretreatment MRI, can predict sustained complete response to radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC). METHODS: In this IRB-approved study, patients were selected from a maintained six-year database of consecutive patients who underwent both pretreatment MRI imaging with a probable or definitive imaging diagnosis of HCC (LI-RADS 4 or 5) and loco-regional treatment with RFA. An experienced radiologist manually segmented the hepatic nodules in MRI arterial and equilibrium phases to obtain the volume of interest (VOI) for extraction of 107 quantitative textural features, including shape and first- and second-order features. Statistical analysis was performed to evaluate associations between textural features and complete response. RESULTS: The study consisted of 34 patients with 51 treated hepatic nodules. Sustained complete response was achieved by 6 patients (4 with single nodule and 2 with multiple nodules). Of the 107 features from the arterial and equilibrium phases, 20 (18%) and 25 (23%) achieved AUC >0.7, respectively. The three best performing features were found in the equilibrium phase: Dependence Non-Uniformity Normalized and Dependence Variance (both GLDM class, with AUC of 0.78 and 0.76, respectively) and Maximum Probability (GLCM class, AUC of 0.76). CONCLUSIONS: This pilot study demonstrates that a radiomic analysis of pre-treatment MRI might be useful in identifying patients with HCC who are most likely to have a sustained complete response to RFA. Second-order features (GLDM and GLCM) extracted from equilibrium phase obtained highest discriminatory performance.

ABSTRACT

Introducción: Actualmente se prefieren procedimientos mínimamente invasivos como las técnicas endovasculares para el tratamiento de la insuficiencia de vena safena mayor que pueden ser por ablación térmica, química o mecánica. Éstos tienen la ventaja de ser ambulatorios, presentar menos complicaciones postoperatorias, una rápida incorporación laboral y mejores resultados estéticos. El objetivo de este estudio es evaluar los resultados del tratamiento con radiofrecuencia versus crosectomía safenofemoral más oclusión endovascular distal. Material y Métodos: Estudio descriptivo prospectivo que incluyó a todos los pacientes con diagnóstico de insuficiencia de la vena safena mayor de enero 2017 a octubre 2019. La elección de la técnica a utilizar se hizo al azar. Resultados: El 77% correspondió al género femenino, con edad media 49 años, el estadío C:2 de la clasificación clíica CEAP fue la más frecuente (57%) y el shunt tipo 3 (63%). La ablación por radiofrecuencia se realizó con mayor frecuencia (83%). El dolor y parestesias (fueron las complicaciones más frecuentes en ambos grupos sin diferencias estadísticamente significativas (p = 0.1470). No hubo diferencias estadísticamente significativo entre las dos técnicas quirúrgicas realizadas en resultado estético (p = 0.4456), el retorno de actividades cotidianas (p = 0.992) ni las laborales (p = 0.901). Conclusiones: Tanto la ablación por radiofrecuencia de la vena safena mayor como la crosectomía safenofemoral más oclusión endovascular distal se consideran dos métodos seguros y efectivos para tratar insuficiencia de vena safena mayor; ya que los resultados finales fueron similares para ambas técnicas quirúrgicas.

ABSTRACT

Objective:To explore the nursing characteristics of patients with atrial fibrillation in "zero ray" transcatheter radiofrequency ablation, and to analyze the postoperative surgical indexes, nursing indexes and anxiety level.Methods:A total of 127 patients who underwent radiofrequency ablation of atrial fibrillation in Xuanwu Hospital, Capital Medical University from October 2018 to September 2020 were divided into the control group ( n=64) and the observation group ( n=63) by random number table method. Patients in the control group received conventional radiofrequency ablation for atrial fibrillation and received conventional nursing care. The observation group made full use of the advantages of the three-dimensional mapping system, using "zero-ray" green electrophysiological technology to complete the intervention of the control group, and parallel personalized nursing intervention measures. The operative indexes, nursing indexes, anxiety and pain levels of 2 groups were compared. Results:The ablation time, total operation time in the control group were (1 917.38±157.74) s, (110.32 ± 35.83) min, respectively, and those in the observation group were (1 915.87±87.19) s, (109.45 ± 28.92) min, and the difference between the two groups was statistically significant ( t value was 1.201, 0.150, P>0.05). The nursing satisfaction score, the time spent with nurses, and the awareness rate of education in the control group were (90.00±3.00) points, (30.36±7.58) min, 68.75%(44/64), respectively, and those in the observation group were (95.00±5.00) points, (40.27±10.68) min, 85.71%(54/63), the difference between the two groups was statistically significant ( t value was -6.845, -6.037, χ2 value was 5.185, all P<0.05). The anxiety score and pain score in the control group were 10.42±2.54 and 7.34±1.55, respectively, and those in the observation group were 6.34±1.21 and 4.64±0.92, respectively. The difference between the two groups was statistically significant ( t value was 11.526, 11.913, both P<0.01). Conclusions:Green electrophysiology transcatheter radiofrequency ablation is a safe, effective and feasible method, and the nursing satisfaction is improved.

ABSTRACT

Objective:To research the occurrence regularity and influencing factor of acute moderate and severe abdominal pain after radiofrequency ablation (RFA).Methods:Cross-sectional study was used to collect patients with primary liver cancer treated by RFA from January 2019 to July 2020 in a hospital. The patients were divided into abdominal pain group ( n=35) and non -pain group ( n=133). The data of 2 groups was analyzed by univariate analysis. The statistically significant factors were analyzed by multivariate Logistic regression analysis, and to explore the risk factors. Results:A total of 168 patients were enrolled in this study; Multiple liver tumors (the number of tumors≥3), lager focus diameters (diameter≥3cm) and a history of pain after RFA were independent predictors of acute moderate and severe abdominal pain ( χ2 values were 21.713, 17.454, 7.953, P<0.01). Conclusion:The incidence of acute moderate and severe abdominal pain after RFA is high. Evaluating risk factors can provide reference for postoperative pain management.
