ABSTRACT
Objective To evaluate the feasibility,safety,post-operative short and long-term outcomes of laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric carcinoma without serosal invasion.Method From May 2007 to May 2013,54 cases of advanced gastric antral cancer without serosal invasion underwent laparoscopic-assisted D2 radical distal gastrectomy (laparoscopic group),54 demographically and pathologically-matched cases undergoing open surgery served as control.The surgical risk,post-operative recovery and follow-up results were compared.Result Surgery was successful in all patients.The mean operation time in laparoscopic group and open group was (168 ± 31) mins and (157 ±20) min respectively,the difference was significant (t =2.237,P =0.027) ; Intra-operative blood loss was (151 ± 56) ml and (213 ± 86) ml (t =4.45,P =0) ; Post-operative intestinal function recovery time was (2.7 ± 0.7) d and (3.4 ± 0.5) d (t =5.4,P =0) ; Lymph node dissection number was (26.4 ± 4.2) and (24.8 ±5.2) (t =1.769,P=0.08).Post-operative complication rate was 4％ and 11％ (P =0.142).There was no perioperative mortality in either group.Post-operative pathological stage of Ⅰ B,Ⅱ A,Ⅱ B,ⅢA was 8,17,24,5 cases in laparoscopic group and 9,14,23,8 cases in open surgery group.108 cases were followed up from 7 to 79 months.In laparoscopic group,8 cases had local recurrence or distal mestastasis,and 4 cases died from tumor; In open group,9 cases had local recurrence or distal mestastasis,and 6 cases died from tumor.Conclusions Laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric cancer without serosal invasion is feasible,safe and advantageous in minimal invasion and rapid recovery,with good short and long-term outcomes.
