ObjectiveTo study the factors associated with meningioma peritumoral edema.MethodsPeritumoral edema of 18 patients was assessed on a semi - quantitative form from preoperative radiography. All the patients' clinical information( tumor size, tumor envelope damage, brain surface vein compression, pathological type), malignancy of tumor tissue, vascular endothelial growth factor(VEGF), immuno-histo-chemisty stain were studied to find out the correlation with peritumoral edema. Results There was no correlation between tumor size, pathological type and brain vein compression with peritumoral edema。 Tumor envelope damage and VEGF immunoreactivity were strongly associated with peritumoral edema. ConclusionThese data suggest that meningioma peritumoral edema may bea result of tumor cell producing VEGF in combination with tumor envelope damage, which lead to the damage of normal blood brain barrier and the enterance of edema-causing chemical factor.

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.

Objective:To investigate the value of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced MRI in predicting the pathological grade and early recurrence rate of hepatocellular carcinoma.Methods:The imaging data, pathological data, and follow-up data of 90 patients with hepatocellular carcinoma who underwent Gd-EOB-DTPA-enhanced MRI examination and surgical treatment in People's Hospital of Baise from January 2016 to October 2017 were retrospectively analyzed. The correlation between the signal intensity of contrast-enhanced MRI and postoperative pathological grade was analyzed. Kaplan-Meier survival analysis was performed to investigate the effects of the signal characteristics of hepatobiliary lesions on the early recurrence rate of hepatocellular carcinoma.Results:A total of 59 (65.56%) patients showed low-intensity signals and 31 (34.44%) patients showed mixed-intensity signals. High-intensity signal was not found in any patients. The signal intensity of the hepatobiliary phase was significantly correlated with the pathological grade of the tumor ( χ2 = 2.26, P = 0.040) and tumor size ( t = 3.10, P = 0.033). The early recurrence rate of hepatocellular carcinoma was significantly higher in patients exhibiting mixed-intensity signals than that in patients exhibiting low-intensity signals ( χ2 = 2.25, P = 0.041). Conclusion:Gd-EOB-DTPA-enhanced MRI in the hepatobiliary phase with different signal intensities has the potential to predict the pathological grade and early recurrence rate of hepatocellular carcinoma.

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.

Objective:
To study hemihepatectomy combined with a circular-stretching suturing technique in bile duct anastomosis in treatment of high level bile duct injuries (BDI).
Methods:
From January 2000 to January 2018, eleven patients with high level BDI caused by laparoscopic cholecystectomy (LC) were treated in Mianyang Central Hospital with hemihepatectomy combined with a circular-stretching suturing technique in the bile duct anastomosis. The hilar confluence was involved in all these patients. A total of six patients had combined right hepatic artery injury with 1 having associated right portal vein injury. A total of five patients had developed right liver atrophy. The median time interval from LC to hepatectomy was 17.0(2.0~61.0) months. The number of previously attempted biliary repairs was 1~4 times (median 2 times). The bile duct anastomosis was performed by the circular-stretching suturing technique.
Results:
There was no perioperative death. One patient underwent left hemihepatectomy and 10 patients right hemihepatectomy. Roux-en-Y hepaticojejunostomy was carried out in 9 patients, and bile duct end-to-end anastomosis in 2 patients. The operation time was (245.9±87.4) min, intraoperative blood loss (655.7±413.6) ml, and the median postoperative hospital stay 12.0(7.0~29.0) days. Five patients developed complications. The median follow-up was 47.0(15.0~89.0) months. One patient developed anastomotic stenosis and 1 patient had cholangitis. The remaining 9 patients were well.
Conclusion
After adequate preoperative preparation, patients who were treated with hemihepatectomy combined with the circular-stretching suturing technique for bile duct anastomosis to treat high level BDI achieved good results.
