Efficacy observation of laparoscopic surgery for treatment of distal advanced gastric cancer / 肿瘤研究与临床

ABSTRACT

Objective To investigate the therapeutic efficacy of laparoscopic surgery for treatment of the patients with advanced gastric cancer.Methods A total of 120 patients with advanced gastric cancer treated by D2 radical resection of distal gastric cancer from January 2015 to January 2017 in Affiliated Hospital of Guangdong Medical University were retrospectively analyzed.According to the method of operation,the patients were divided into laparoscopic group (60 cases) and laparotomy group (60 cases).The operation-related indexes,operation curative effect indexes and postoperative recovery were compared between the two groups by using x 2 test and t test.Results The operation time of the laparoscopic group was longer than that of the laparotomy group [(197±21) min vs.(178±23) min,t =4.759,P ＜ 0.001].Some parameters in the laparoscopic group were lower than those in the laparotomy group (all P ＜ 0.05),including intraoperative blood loss [(111±30) ml vs.(221±52) ml,t =14.103],the length of the surgical incision[(6.1±1.3) cm vs.(17.3±3.2) cm,t =25.117],postoperative anal evacuation time [(90±14) h vs.(110±18) h,t =6.983],the postoperative bed-out time [(2.9±0.8) d vs.(4.8±1.4) d,t =9.127],the postoperative liquid dietary intake time [(4.3±0.9) d vs.(5.7±1.2) d,t =7.230],and hospital stay time [(13.2±2.5) d vs.(15.5±3.2) d t =4.387].There were no statistical differences in the number of removed lymph nodes,the number of first-site removed lymph nodes,the number of second-site removed lymph nodes,the distance from the distal margin to the tumor,and the distance from the proximal margin to the tumor (t values 1.351,0.912,1.240,0.876,and 0.840 respectively,all P ＞ 0.05);The incidence of operative complications in the laparoscopic group was lower than that in the laparotomy group [6.67 ％ (4/60) vs.20.00 ％ (12/60),X 2 =4.615,P =0.032].Conclusion Laparoscopic surgery in the treatment of advanced gastric cancer patients has a favorable effect,with reliable results,less trauma,postoperative recovery and fewer complications.
