ABSTRACT
Objective This study aimed at evaluating the safety and feasibility of transumbilical single site laparoscopic appendectomy (SSLA) by systematic review and Meta analysis of literature comparing with conventional tree-port laparoscopic appendectomy (CLA).Methods The articles published from January 2000 to December 2012 were searched from electronic databases of PubMed,Embase,and the Cochrane Library.The literature with comparative studies of SSLA with CLA for adult patients was selected.And,the systematic review and Meta analysis carried out using Stata software.Results Eleven articles with 998 cases receiving operation during March 2008 to October 2011 were enrolled into study.There were 435 cases with SSLA and 563 cases with CLA.Compared the cases with SSLA and cases with CLA,there was no difference significantly in operative time (z =1.48,P =0.140),pain score in the 24 hours after surgery (z =0.83,P =0.409),diet start(z =0.38,P =0.707),postoperative complications (z =0.46,P =0.647),hospital stay (z =0.36,P =0.722).Conclusions SSLA are not different in operative time,postoperative pain,diet start,postoperative complications,hospital time comparing with that in CLA.
ABSTRACT
The etiology of familial gastric cancer (FGC) are E-cadherin (CDH1) mutations,helicobacter pylori infection,etc.The median age of patients with FGC is 50-65 years old.The male-female sex ratio is 2 ∶ 1.The most of tumors of FGC locate in distal stomach and present diffuse type in histological classification.It is reported that the people who has a family history of gastric cancer especially for those parents has an increased risk of gastric cancer.It is difficult to find FGC in early stage by current technology.The preventive methods include eradication of helicobacter pylori and prophylactic total gastrectomy,etc.
ABSTRACT
Objective To evaluate the effect of the gastric signet ring cell cancer(SIG)on the T,N,M stages. Methods Three hundred and fifty-one patients undergoing D2 or greater gastrectomy for gastric cancer were ana lyzed retrospectively.The T,N,M stages of 59 patients with SIG and 161 patients with tubular adenocarcmonla (TUB)were compared using univariate and multivariate analysis.Results The chi-square test showed that there were not significant differences in T,N,M stages between TUB and SIG.Multivariate Logistic regression analysis indicated that SIG Was not a independent factor influencing the T,N.M stage.Conclusion Gastric cancer with SIG has not higher T,N,M stages than that with TUB.
