Objective Comparing the difference in postoperative recurrence,complications,quality of life and cosmetic results between patients receiving radical mnastectomy and breast conserving surgery,provides an evidence of breast conserving surgery superior to radical mastectomy.Methods A retrospective analysis of 477 breast cancer patients cases in Department of General Surgery,Third People's Hospital of Baoji City from January 2009 to January 2012.These patients were divided into two groups:the control group 229 cases (48％) underwent conservative surgery treatment and the observation group 248 patients (52％) underwent radical surgery.Using SPSS15.0 statistical software analysis and compare with recurrence,postoperative complications,breast cosmetic effect and quality of life for these two groups of patients.Results In breast-conserving group compared with radical mastectomy group,the one and two year recurrence or metastasis rate were not statistically different between the two groups (P ＞ 0.05),the incidence of postoperative complications was significantly decreased (P ＜ 0.05).The scores for quality of life between the breast-conserving group and radical mastectomy group were all significantly different (P ＜ 0.05).Excellent cosmetic results in breast-conserving group was 78.52％,which was significantly higher than that in the radical mastectomy group (61.34％),the difference was statistically significant (x2 =5.86,P ＜ 0.05),The two groups are not significant in overall survival time (x2 =3.154,P ＞ 0.05) and progression free survival (x2 =4.243,P ＞ 0.05) as two indicator of long-term efficacy.Conclusions Conservative surgery compared with radical mastectomyhave less clinical complications,more breast cosmetic effect,better survival quality,and both of them share the same recurrence or metastasis and survival rate,so conservative surgery should be preferable in the clinical application.

ObjectiveTo systematically evaluate the advantages and disadvantages of choledochoscopic gallbladder-preserving cholelithotomy (CGPC) and laparoscopic cholecystectomy (LC) in the treatment of gallstones. MethodsThe databases of CBM, CNKI, VIP, Wanfang Data, PubMed, EMBASE, the Cochrane Library, and Web of Science were searched for randomized controlled trials (RCTs) related to CGPC and LC in the treatment of gallstones published up to June 2015. Data extraction and quality evaluation were performed for the literature included, and Review Manager 5.3 was used for the meta-analysis. ResultsFive RCTs involving 685 patients were included. The results of the meta-analysis showed that CGPC group and LC group had significant differences in operation time (OR=8.85, 95% CI: 049-17.21, P=0.04) and incidence of postoperative diarrhea (OR=0.24, 95% CI: 0.11-0.53, P=0.000 4). However, no significant differences were seen between the two groups in intraoperative bleeding volume (OR=-12.37, 95% CI: -29.73-4.99, P=016), time to postoperative intestinal function recovery (OR=-7.19, 95% CI: -24.28-9.90, P=0.41), hospitalization days (OR=-0.17, 95% CI: -1.98-1.63, P=0.85), and hospital costs (OR=-1.14, 95% CI: -2.57-0.28, P=0.12). ConclusionThe operation time and incidence of postoperative diarrhea in CGPC are superior to those in LC, while no significant differences are observed in intraoperative bleeding volume, time to postoperative intestinal function recovery, hospitalization days, and hospital costs. Due to a limited number of articles included and publication bias, RCTs with a large sample size and high quality are needed to provide more effective data.
