ABSTRACT
Objective To compare the efficacy and safety of single-incision and conventional three-port laparoscopic appendectomy.Methods According to the Cochrane systematic review methods,literatures on the comparison of the effects of single-incision laparoscopic appendectomy (SILA) and conventional three-port laparoscopic appendectomy (CTLA) were searched for in the PubMed,EMBASE,the Cochrane Controlled Trials Register,CNKI,CBM and VIP database.Data including the operation time,pain visual analogue scales scores,duration of postoperative hospital stay,incidence of postoperative complications,mean time of hospital stay and cost between the SILA and CTLA were compared by 2 reviewers.RevMan 4.2 software was used for Meta analysis,and the heterogeneity of the study was analyzed using the 12 test.Categorical variables were presented by odds ratio and 95％ confidence interval (95％ CI),and continuous variables were presented by weighted mean difference (WMD) and 95％C1.Results Eight randomized controlled trials including 1 444 patients were selected.All the patients were subdivided into the adults group (760 patients) and the children group (684 patients).A total of 721 patients received SILA (SILA group) and 723 received CTLA (CTLA group).The operation time of patients who received SILA in the adults group and the children group were significantly longer than those who received CTLA (WMD =4.40,7.39,95％ CI:2.14-6.66,2.16-12.61,P ＜0.05).There were no significant difference in the pain visual analogue scales scores,incidence of postoperative complications and duration of hospital stay between patients who received SILA and CTLA in the adults group and the children group (WMD =-0.34,95 ％ CI:-1.02-0.33,OR=0.97,95％CI:0.64-1.47; WMD=-0.19,95％CI:-1.14-0.76,P＞0.05).The cost of patients who received SILA was significantly higher than those who received CTLA in the children group (WMD =0.87,95 ％ CI:0.26-1.48,P ＜ 0.05).Conclusions There is no obvious advantages of SILA in perioperative and postoperative outcomes when compared with CTLA.Therefore,SILA is only a possible alternative to CTLA other than the preferred method.
ABSTRACT
The adipokines is a class of active substances secreted by adipose tissue,with the function of regulating the body glucose balance and others.Some experiments prove Roux-en-Y gastric bypass postoperative plasma levels of adipokines will change that play an important role in improving islet function in the treatment of type 2 diabetes mellitus.Here,the author will make a review about the adipokines role in pathways and postoperative level changes,etc,in order to further explore the mechanism of the surgical treatment of diabetes.
