RESUMO
Objective To evaluate the effects of different optional time leading to complication and prognosis by laparoscopic cholecystectomy.Methods Search all of clinical randomized trials on early and delay laparoscopic cholecystectomy in CNKI database.The RevMan 5.0 software was used to conduct the Meta-analysis,which was carried out by collecting information based on inclusion and exclusion criteria from all trails' information available,and the pubhcation bias analysis and the susceptivity analysis was also evaluated to make sure the results stable.Results There was significant statistical difference in conversion,surgery time,complication and postoperative hospitahzation time between the ＜ 72 h group and ＞ 72 h group (P ＜ 0.05).Conclusions Meta-analysis shows that in the laparoscopic cholecystectomy progress,the surgical outcome is best with 72h,which can short the surgery and postoperative hospitalization time,reduce the complication and decline the conversion.
