ABSTRACT
Objective To analyze the effects of laparoscope-assisted Ivor-Lewis surgery on perioperative stress,immune responses and intestinal barrier function in elderly patients with esophageal cancer.Methods A prospective study including 55 elderly esophageal cancer patients undergoing laparoscope-assisted Ivor Lewis surgery (the treatment group,n =25) and Ivor-Lewis surgery(the control group,n=25) was conducted.The white blood cell count,neutrophil-to-lymphocyte ratio,percentages of CD4 and CD8 cells,CD4/CD8 ratio,C reactive protein (CRP) and D-lactic acid levels were compared between the two groups before and at 1,4 and 7 d after operation.Results The white blood cell count(t =2.689,P =0.010) and neutrophil-to-lymphocyte ratio (t =3.300,P =0.002)were lower in the treatment group than in the control group at 1 d after operation.The percentage of CD4 cells was higher in the treatment group than in the control group at 1 d(t =2.242,P =0.029)and 4 d(t =2.031,P =0.047) after operation.The percentage of CD8 cells was higher in the treatment group than in the control group at 1 d after operation(t =2.041,P=0.046).The CD4/CD8 ratio was higher in the treatment group than in the control group at 1 d(t =2.833,P =0.007)and 4 d(t=2.111,P=0.036)after operation.The CRP level was lower in the treatment group than in the control group at 1 d(t=2.267,P=0.028)and 4 d(t =2.111,P =0.036)after operation.The D-lactic acid level was lower in the treatment group than in the control group at 1 d(t =2.267,P=0.028),4 d (t =7.967,P ＜ 0.01) and 7 d (t =2.541,P =0.014) after operation.Conclusions Laparoscopeassisted Ivor-Lewis surgery has good protective effects on perioperative stress,immune responses and intestinal barrier function in elderly patients with esophageal cancer.
ABSTRACT
Objective To compare the effect of breast conserving surgery and modified radical mastectomy on the clinical efficacy of patients with early breast cancer.Methods CNKI,Chinese Journal Full-text Database (CJFD),China Biology Medicine Disc (CBMdisc),China Dissertation Database (Chinese Dissertation Database,CDDB) google academic and other databases were comprehensive searched.And then the search time was limited to between January 1,2015 and September 1,2017.Key words can be locked for breast conserving surgery,improved surgery for breast surgery,case-control studies,etc.,and then meet the conditions of the literature into the study,for a retrospective analysis.The authors reviewed the literature independently,extracted data and evaluated the risk of bias,and used Review Manager 5.3 software for systematic analysis.Results A total of 1 093 patients with early breast cancer were enrolled in the study.The Meta-analysis showed:there was a significant difference in operation time between the two groups(MD =-30.71,95％ CI:-31.96--29.46,P ＜ 0.01);there was a significant difference in intraoperative blood loss between the two groups(MD =-53.30,95％ CI:-55.38--51.22,P ＜ 0.01);there was a significant difference in postoperative hospital stay (MD =-5.66,95％CI:-7.17--5.17,P ＜0.01) and the incidence of complications (OR =0.30,95％ CI:0.19-0.47,P ＜ 0.01)compared with modified radical mastectomy in early breast cancer patients.There was no significant difference between the two groups in the postoperative recurrence and metastasis (OR =0.78,95％ CI:0.54-1.13,P =0.19).Conclusions In the choice of surgical methods,breast-conserving therapy is better than modified radical surgery,and postoperative recurrence and metastasis rate has no significant difference.
