ABSTRACT

Objective:To investigate the safety and effect of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and sorafenib on large hepatocellular carcinoma (HCC) patients treatment.Methods:From Jan 2012 to Dec 2017, 36 patients (Male: 33, Female: 3, average age: 51.8) with large HCC lesions(5-7 cm) received TACE plus with RFA and sorafenib in the Third Affiliated Hospital of Sun Yat-sen University. Efficacy was evaluated after TACE. Each patient was received follow-up after RFA procedure. The occurrence rate of complications and overall survival (OS) were recorded. Log-rank univariate analysis was used to analyze the OS data.Results:The median TACE time was 4, and the RFA time was (1.7±0.7) . Mean duration time of sorafenib administration was (37.7±28.8) months. Adverse events of sorafenib: 26(72.2%) hand-foot skin reaction, 6(16.7%) hypertension, 22(61.1%) diarrhea, 17(47.2%) alopecia, 3(8.3%) oral ulcer and 1(2.8%) gastrointestinal hemorrhage. Median OS was 63.0 months, and 1-year, 3-year and 5-year survival rate was 100%, 72.7% and 52.6%. The cumulative survival rate of patients taking whole course of sorafenib ( n=21) was better than that of patients taking remedial ( n=15); the cumulative survival rate of patients with alpha fetal protein (AFP) <200 μg/L ( n=26) before treatment was better than ≥200 μg/L ( n=10); the cumulative survival rate of patients with good TACE response ( n=19) was better than that of patients with no response ( n=17), and the differences were statistically significant (all P<0.05). Conclusions:TACE plus with RFA and sorafenib are safe and effective for large HCC patients with 5-7 cm lesions and this treatment might improve OS. The whole-course sorafenib, lower base AFP value (<200 μg/L) and good TACE response were considered as the good factors for the combination therapy in large HCC patients.

ABSTRACT

Objective To investigate the efficacy and safety of percutanous transhepatic intrahepatic portosystemic shunt(PTIPS)for chronic portal vein occlusion and cavernous transformation with symptomatic portal hypertension.Methods The clinical and imaging data of 38 patients with chronic portal vein occlusion and cavernous transformation with symptomatic portal hypertension, who received PTIPS in our hospital from November 2009 to June 2016,were analyzed retrospectively.The differences of the portosystemic pressure gradient(PPG)measured before and after PTIPS procedure was analyzed by a paired samples t-test. All the patients were followed up and the curative effect and operation-correlated complications were observed.Results The PTIPS procedure was technically successful in 36 patients.The other two patients with unsuccessful PTIPS underwent medical treatment,and one of them died of recurrent variceal bleeding 25 months later. Effective portal decompression and free antegrade shunt flow were achieved in 36 patients with successful PTIPS.And the mean PPG was decreased from(25.2±2.9)to(13.2± 1.3) mmHg (1 mmHg=0.133 kPa) before and after PTIPS respectively and the difference was statistically significant(P<0.05).During the procedure,arterial hemorrhage occurred in two patients who subsequently underwent embolization. Biliary injury occurred in one case and percutanous transhepatic biliary drainage (PTBD)was then performed.The mean follow-up period of the 36 patients was(26.7±10.4)months(range from 3.0 to 74.0 months).Hepatic encephalopathy appeared in 4 cases,among which,3 patients recovered after receiving medical treatment, while 1 patient experienced Grade 3 hepatic encephalopathy and recovered after implanting a smaller cover-stent.Shunt dysfunction occurred in 10 cases,of which 8 cases recovered after shunt revision with stent implantation or ballon angioplasty, while 2 cases underwent anticoagulation by warfarin only. During follow-up period, 7 patients died of liver failure(n=4), hepatic cellular carcinoma(n=1), recurrent varicose vein bleeding(n=1), and renal failure(n=1). The other patients remained asymptomatic and shunt patency. Conclusions PTIPS is both safe and effective for the treatment of symptomatic portal hypertension caused by chronic portal vein occlusion and cavernous transformation.The technical success rate is high,and the short-term curative effect is satisfied.

ABSTRACT

Objective To study the feasibility and efficacy of percutaneous transhepatic intrahepatic portosystemic shunt (PTIPS) in patients with portal hypertension due to chronic portal vein occlusion after splenectomy.Methods 27 patients who had portal hypertension due to chronic portal vein occlusion after splenectomy underwent PTIPS between December 2010 and March 2015.These patients were enrolled in this retrospective study.The success rates,efficacy,and complications were evaluated.Significance in the differences in the portosystemic pressure gradient (PPG) as measured before and after PTIPS procedure was assessed.Results PTIPS was successfully carried out in 25 patients but failed in 2.No fatal procedural complications were observed.The mean PPG dropped from (22.3 ± 5.7) mmHg to (12.4 ± 3.1) mmHg after successful PTIPS (1 mmHg =0.133 kPa,P <0.05).The median follow-up in the 25 patients with successful PTIPS were 22 months and there were 3 (12.0%) deaths from liver failure due to severe cirrhosis,and 1 death (4.0%) from stroke during the follow-up period.Shunt dysfunction happened in 4 (16.0%) patients.The original symptoms reoccurred in 2 patients (8.0%) and the remaining patients were diagnosed by routine CT or US examination.Three patients recovered after shunt revision with stent implantation or balloon angioplasty,while one patient refused any further therapy except oral medication.This patient suffered from the first episode of rebleeding 36 months after PTIPS.Hepatic encephalopathy developed in 2 (8.0%) patients,1 patient recovered after medical treatment,while the other who developed Grade 3 hepatic encephalopathy recovered after implanting a smaller cover stent.The remaining patients were asymptomatic with patent shunts.Conclusion PTIPS was a feasible,safe,and efficacious treatment for portal hypertension due to chronic portal vein occlusion after splenectomy.

ABSTRACT

Objective To investigate the technique,efficacy,and safety of percutaneous interventional treatments for biliary complications (BC) after liver transplantation (LT).Methods The clinical and imaging data of 127 patients with BC after LT,who received percutaneous interventional treatments in the Third Affiliated Hospital of Sun Yat-sen University from January 2006 to December 2015,were analyzed retrospectively.On the basis of the cholangiographic appearance,patients were classified into 5 groups:biliary leakage group (n =11),anastomotic biliary strictures group (n=28),hilar biliary strictures group (n =30),multifocal biliary strictures group (n =51),and bilomas group (n =7).The modality of interventional treatments was percutanous transhepatic biliary drainage (PTBD),PTBD combined with balloon dilation,PTBD combined with balloon dilation and stent implantation.The methods of biliary drainage included external drainage and external-internal drainage.All the patients were followed up after treatment.The curative effect and operation-correlated complications were observed.Results The first successful rate of PTBD was 97.6% (124/ 127).The total curative rate,improvement rate and inefficacy rate of interventional treatments were 37.8% (48/127),44.9% (57/127) and 17.3% (22/127) respectively.In biliary leakage group,all the patients were cured by percutaneous interventional treatments with the curative rate being 100%.In anastomotic biliary strictures group,the cure and improvement rates were 64.3% (18/28) and 35.7% (10/28) respectively.The efficacy rate was 100% (28/28).In hilar biliary strictures group,the cure,improvement and inefficacy rates were 40% (12/30),53.3% (16/30) and 6.7% (2/30) respectively.The efficacy rate was 93.3% (28/30).In multifocal biliary strictures group,the cure,improvement and inefficacy rates were 13.7% (7/51),54.9% (28/51) and 31.4% (16/51) respectively.The efficacy rate was 68.6% (35/51).In bilomas group,3 cases (3/7) obtained improvement and treatment of 4 cases was inefficative.The efficacy was the best for the patients with bilary leakage,and it was the worst for the patient with bilomas (P<0.001).The main operation-correlated complication was bile tract infection during drainage.The rates of bile tract infection were 32.4% (34/105) and 81.8% (18/22) in patients with external drainage and external-internal drainage,respectively.There was statistically significant difference between these two items (P< 0.001).Conclusion PTBD combined with balloon dilation and biliary stent implantation is a safe and effective therapeutic modality for BC after LT,which can improve patients' clinical symptoms,improve patients' quality of life.The patients with bilomas should be treated by retransplantation as soon as possible.The biliary external drainage can decrease the rate of biliary tract infection significantly.
