RESUMO
Objective To explore the influence of preoperative transarterial chemoembolization on short-term prognosis in patients with hepatocellular carcinoma after liver transplantation Methods From Jan 2006 to Sep 2016 in Ruijin Hospital 21 patients received preoperative hepatic transarterial chemoembolization (TACE) before liver transplantation,the other 30 patients undergoing upfront liver transplantation served as control group.Results No statistical difference was found in the total operation time (401 ± 72) min vs.(377 ± 100) min,blood loss (2 785 ± 25 56) ml vs.(4 199 ± 3 748) ml and length of hospital stay (32-± 16) d vs.(28 ± 17) d between two groups,and the occurrence rate of vascular complications (14.3％ vs.0) or biliary complications (9.5％ vs.6.7％) also showed no difference (P ＞ 0.05).Although more patients were diagnosed with postoperative infection in the observation group (81％ vs.40％) (P ＜ 0.05),there was no statistically significant difference in complication grade and perioperative mortality between two groups (P ＞ 0.05).There's no remarkable difference in the liver function recovery level between two groups in terms of postoperative indexs of liver function such as TBL,ALT,AST,and there was also no statistical difference between two groups in 1-year,2-year and 3-year overall survival (P ＞ 0.05).The waiting time in the study group was significantly longer than that in the control group (P ＜ 0.05),and the incidence of postoperative immune dysfunction was lower than that of the control group (P ＜ 0.05).Conclusion Preoperative TACE does not affect liver function recovery and perioperative safety after liver transplantation.
RESUMO
Objective To systematically evaluate the effect of preoperative transarterial chemoembolization (TACE) on perioperative safety of patients with resectable hepatocellular carcinoma (HCC).Methods Literatures were researched using Chinese Journal Full-text Database,Wanfang database,VIP database,PubMed,Medline from December 1,1994 to May 30,2016 with the key words including “肝细胞癌,肝切除,术前化疗栓塞,经动脉化疗栓塞,liver cancer,hepatocellular carcinoma,liver resection,hepatectomy,transcatheter arterial chemoembolization,transarterial chemoembolization,preoperative” Manual retrieval was also conducted simultaneously.The randomized controlled trials (RCTs) about TACE on perioperative safety of patients with resectable HCC were received and enrolled.Patients undergoing surgery after preoperative TACE were allocated into the case group and patients undergoing first-stage resection were allocated into the control group.Two reviewers independently screened literatures,extracted data and assessed the risk of bias.Count data were described as relative risk (RR) and 95％ confidence interval (CI).Measurement data were represented as standardized mean difference (SMD) and 95％CI.The heterogeneity of the studies was analyzed using the I2 test.Results Five RCTs were enrolled in the Meta analysis,and the total sample size was 430 cases including 212 in the case group and 218 in the control group.Results of Meta analysis showed that there was no statistically significant difference in the hemihepatic resection rate between the 2 groups (RR=0.99,95％CI:0.81～ 1.20,P＞0.05).The combined resection rate of perihepatic organs in the case group was significantly higher than that in the control group (RR=3.42,95％CI:1.91-6.12,P＜0.05).Results of subgroup analysis showed that operation time and incidence of postoperative complications of patients with an average tumor diameter ＞5 cm in the case group were respectively longer and higher than these in the control group (SMD=0.31,RR=1.65,95％CI:0.06-0.57,1.01-2.69,P＜0.05).Conclusion There is no obvious effect of preoperative TACE on resectable HCC,and it can evaluated combined resection rate of perihepatic organs,operation time and incidence of postoperative complications of patients with resectable HCC and an average tumor diameter ＞ 5 cm,and also reduce the perioperative safety.
RESUMO
0.05).The comparison of operating time and hospital stay was not performed due to insufficient data.Conclusion:Relative small J-pouch and straight anastomos is provided similar early results after low anterior resection.Both of these methods were proved to be safe and effective.
