Radical versus conservative surgical treatment of liver hydatid cysts: a meta-analysis / 医学前沿

To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.

Comparison of the therapeutic efficacy of combined intracavitary therapy with palliative surgery in patients with extrahepatic ductal cholangiocarcinoma / 中华肝胆外科杂志

Objective To compare the therapeutic efficacy of combined biliary stent and 125I seed intracavity irradiation with palliative surgery in the treatment of extrahepatic ductal cholangiocarcinoma.Methods A prospective analysis was conducted on 142 patients with cholangiocarcinoma who were treated in The First Affiliated Hospital of Bengbu Medical College from January 2012 to December 2015.There were 80 patients who underwent percutaneous biliary metal stenting combined with 125I particles implantation (the stenting-particle group) and 62 patients who were treated by palliative biliary drainage (the surgical group).The surgical group included R1 resection in 17 patients,R2 resection in 26 patients and biliary enteric drainage in 19 patients).The levels of jaundice,liver function,survival time,hospitalization time and hospitalization cost before and after therapy were analyzed.Results Jaundice was effectively alleviated in the two groups after a short period.The liver function in the 2 groups improved significantly at 1,3 and 6 months when compared with that before operation,(P ＜ 0.05).The average hospitalization time of the stenting-particle group and the surgery group were (16.5 ± 5.0) days and (25.5 ± 10.5) days,respectively,(P ＜ 0.01).The average hospitalization cost of the stenting-particle group and the surgery group were (39 622.0 ± 7 666.4) yuan and (59 562.0 ± 24 218.2) yuan,respectively,(P ＜ 0.05).The average survival time of the stenting-particle group and the surgery group were (12.2 ± 5.1) months and (12.69 ± 7.46) months,respectively,and the difference was not significantly different (P ＞ 0.05).Conclusions For patients with extrahepatic ductal cholangiocarcinoma who were not suitable for radical surgery,percutaneous biliary stenting combined with 125I seed brachytherapy effectively reduced jaundice,improved liver function,shortened average length of hospital stay and reduced average cost of hospitalization.When compared with palliative surgery,it was a minimally invasive,easy,safe and efficacious treatment,especially for elderly patients with poor physical conditions.
