Objective To evaluate the safety and feasibility of step-by-step balloon dilatation combined with contineous biliary drainage in treating benign biliary-enteric anastomosis stricture.Methods The clinical data and imaging materials of 49 patients with benign biliary-enteric anastomosis stricture,who were admitted to authors' hospital during the period from January 2008 to March 2014 to receive treatment,were retrospectively analyzed.Before treatment,the diagnosis of benign biliary-enteric anastomosis stricture was confirmed in all patients by color Doppler ultrasound,MRI and/or contrast-enhanced CT scan,endoscopic or DSA-guided anastomosis biopsy.Among the 49 patients,23 patients (study group) were treated with percutaneous transhepatic step-by-step balloon dilatation (the diameter of used balloon was 8 mm initially,then 10 mm balloon was used in the second month,and 12 mm balloon was used in the third month) together with contineous biliary drainage (lasting for 6 months);26 patients (control group) were treated with single percutaneous transhepatic balloon dilatation (balloon diameter of 6 mm or 8 mm) plus biliary drainage (lasting for 6 months).The improvement of clinical symptoms,the incidence of postoperative complications,and the anastomotic patency rate were compared between the two groups.Results Technical success was obtained in all patients.No procedure-related complications,such as biliary tract hemorrhage and perforation,occurred.One week after the treatment,the difference in bilirubin level between the two groups was not statistically significant (P>0.05).Although the difference in 3-month anastomotic patency rate between the two groups was not statistically significant,the 6-month,12-month and 24-month anastomotic patency rates of the study group were significantly higher than those of the control group (P<0.05).Three patients in the study group developed recurrent jaundice at 11.2,14.3 and 17.6 months after treatment respectively;MRI and contrast-enhanced CT scan confirmed the diagnosis of anastomotic stricture recurrence,and balloon dilatation together with drainage tube placement had to be carried out again.In the control group,16 patients developed recurrent jaundice within 3.1-17.1 months after balloon dilatation management,among them one patient died of disseminated intravascular coagulation and the remaining 15 patients received balloon dilatation together with drainage tube placement again.Conclusion For benign biliary-enteric anastomosis strictures,step-by-step balloon dilatation combined with persistent biliary drainage is a safe and effective minimally-invasive treatment.

Objective To discuss the influence of different antitumor treatments on the survival time of patients with obstructive jaundice caused by cholangiocarcinoma located at middle-low segment of common bile duct after receiving PTCD. Methods During the period from Jan. 2012 to March 2013, a total of 60 patients with pathologically-proved cholangiocarcinoma located at the middle-low segment of common bile duct were admitted to authors’ hospital. According to tumor TNM staging, stage Ⅱ was seen in 9 cases, stage Ⅲ in 39 cases and stage Ⅳ in 12 cases. Based on the degree of cell differentiation, highly differentiated cancer was observed in 9 cases, moderately differentiated cancer in 37 cases, and poorly differentiated cancer in 14 cases. The 60 patients were enrolled in this study. Drainage tube placement and stent implantation were performed in all patients so as to relieve the symptoms of jaundice. According to the antitumor treatment used, the 60 patients were randomly and equally divided into three groups with 20 patients in each group. Draining procedure with subsequent regular arterial infusion chemotherapy was employed in the patients of group A; draining procedure with subsequent particle chain placement in biliary tract was performed in the patients of group B; and draining procedure with subsequent regular arterial infusion chemotherapy together with particle chain placement in biliary tract was carried out in the patients of group C. The results were analyzed using SPSS17.0 statistical software. The death factors of patients were statistically evaluated by using multivariate Cox proportional hazards regression analysis method, P<0.05 was considered that the difference had statistical significance. Results The median survival periods of group A, B and C were (186.0±36.4) days, (183.0±26.5) days and (252.0±43.6) days respectively. The death factors of cancer patients were analyzed by using multivariate Cox proportional hazards regression analysis method, which indicated that tumor stage was a risk factor for death (HR=8.434, 95%CI 3.41-20.090);the treatment mode was a protection factor of death (HR=0.616, 95%CI 0.429-0.884); while the degree of tumor differentiation was unrelated to death(score test,字2=0.197, P=0.657>0.05). The risk of death in group B was not significantly different from that in group A (HR=1.012, 95%CI 0.558-2.179); while the treatment mode of group C was a protection factor of death (HR=0.334, 95%CI 0.148-0.075). Conclusion The TNM stage and treatment mode can influence the survival time of patients with cholangiocarcinoma located at the middle-low segment of common bile duct. Therefore, for the treatment of obstructive jaundice caused by cholangiocarcinoma, combination use of regular arterial infusion chemotherapy and particle chain placement in biliary tract should be employed immediately after draining procedure as this therapeutic mode can effectively prolong patient’s survival time.

ObjectiveTo investigate the effect of arsenic trioxide-loaded CalliSpheres beads (CBATO) in transarterial chemoembolization (TACE) in the treatment of rabbits with VX2 liver tumor. MethodsA total of 120 tumor-bearing rabbits were divided into control group, CalliSpheres beads (CB) group (blank beads for TACE), CBATO group, and conventional TACE (cTACE) group (arsenic trioxide lipiodol for TACE) using a random number table, with 30 rabbits in each group. Five rabbits in each group were sacrificed at 12 hours and on days 3, 7, and 14 after TACE, and immunohistochemistry was used to measure the proliferation index and apoptosis percentage of tumor cells in the residual tumor area. The tumor necrotic volume was measure on day 7 after TACE, and the growth rate and necrosis rate of tumor cells were calculated. Ten rabbits were randomly selected from each group for the observation of survival time. An analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kaplan-Meier survival analysis was used to evaluate survival time, and the log-rank test was used for comparison. ResultsOn day 7 after TACE, the CBATO group had a significantly lower growth rate and a significantly higher necrosis rate of tumor cells than the cTACE group, the CB group, and the control group (all P<0.05). At each time point after TACE, there were significant differences in the proliferation index and apoptosis percentage of tumor cells between the CBATO group and the other three groups (all P<0.05). The median survival time was 26 days in the CBATO group, 18.5 days in the CB group, 22 days in the cTACE group, and 15.5 days in the control group, and the CBATO group had a significantly longer survival time than the other three groups (χ2=3.95, 8.99, and 13.47, P=0.049, P=0.003, and P<0.01). ConclusionCBATO has a better effect than cTACE and CB in the treatment of rabbits with VX2 liver tumor and can significantly improve tumor necrosis rate, promote the apoptosis of tumor cells, and prolong the survival time of experimental animals.

Primary hepatocellular carcinoma(HCC)is a common malignant tumor in the world,and in China it is the fourth most common malignant tumor and the second cause of cancer mortality.In China,most HCC patients are already in the advanced stage when the clinical diagnosis of HCC is confirmed,and it is impossible to adopt a radical treatment for the patient.At present,transarterial chemoembolization(TACE)has become the mainstream therapeutic option for unresectable HCC,and hepatic arterial perfusion chemotherapy(HAIC),as a new therapeutic option,has attracted extensive attention.This article reviews the research progress in TACE combined with HAIC for the treatment of HCC,and obtains the following conclusions:TACE combined with HAIC has better efficacy than TACE along in patients with unresectable HCC of BCLC stage C,massive HCC,and portal venous invasion,but there is no significant difference in the therapeutic efficacy between TACE combined with HAIC and TACE alone for patients with HCC of BCLC stage A/B.It is expected that this review will provide effective recommendations for treating HCC patients in clinical practice,further standardize TACE treatment and later-stage HAIC treatment,and provide the basis for the design of relevant clinical studies.
