Comparison of endoscopic versus open component separation technique for abdominal hernia:a Meta-analysis / 中华普通外科杂志

Objective To evaluate the efficacy and safety of endoscopic versus open component separation technique (CST) for abdominal hernia.Methods Systematic review was carried out to identify the controlled clinical studies comparing endoscopic CST with open CST for abdominal hernia.The Meta-analysis was performed with RevMan 5.2 software.Results The selection criteria was met in five studies.A total of 185 patients with abdominal hernia were included.Analysis of the data suggested that there was no significant differences in recurrence rate between endoscopic CST and open CST(P =0.84,risk difference =-0.01,95％ CI-0.12 to 0.10).However,endoscopic CST compared with open CST was associated with a significant reduction of postoperative wound complications (P ＜ 0.000 1,odds ratio =0.19,95％ CI 0.09 to 0.41).And there was no significant differences in operation time,intraoperative blood loss and postoperative hospital stay (all P ＞ 0.05).Conclusions As compared to open CST,endoscopic CST show equivalent clinical effects with similar recurrence rate.However,endoscopic CST was associated with a significant reduction of postoperative wound complications,and there was no significant differences in in operation time,intraoperative blood loss and postoperative hospital stay.

Surveillance of schistosomiasis in areas along water transfer project from Yangzte River to Hanjiang River in Qianjiang basin / 中国血吸虫病防治杂志

Objective To evaluate the impact of the water transfer project from the Yangtze River to the Hanjiang River on the transmission of schistosomiasis.so as to provide scientific basis for the development of control strategy.Methods A field investigation on snail status,the infection situation of human and cattle as well as related endemic factors was performed in the project areas of the Qianjiang basin.Results There were 33 endemic villages and 48 non-endemic villages along the water transfer project.In endemic villages,the infection rates of human and cattle were 0.42% and 0.48%,respectively.In the endemic area,the snail area was 17.28 hm~2,the mean density of living snails was 0.043 No./0.1 m~2,meanwhile,no snail Was found in the non.endemic areas.Conclusion The surveillance on epidemic situation should be carried out for a long time in order to prevent the spreading of snails.
