title: [Impact of surgical modalities for gastric cancer on operational trauma].
abstract: OBJECTIVE
  To evaluate the impact of surgical modality for gastric cancer on operational trauma.
  
  
  METHODS
  A total of 1499 cases of gastric cancer undergoing surgical procedures were divided into the groups of radical resection (RR, n = 1344) and palliative resection group (NRR, n = 155) according to their surgical modalities. And they were further divided into sub-groups according to the profiles of gastrectomy, extent of lymphadenectomy and multi organic resection. The extent of operational trauma (as evaluated by operative duration, transfusion volume, postoperative hospital day and incidence of complications) was compared in different groups and subgroups.
  
  
  RESULTS
  In RR and NRR groups, median transfusion volume (Q(1), Q(3)) was 0 (0, 600) vs 400 (0, 800) ml respectively. There was significant difference (P < 0.05). No significant difference existed in operative duration, postoperative hospital day or incidence of complications between two groups (all P > 0.05). In cases of distal gastrectomy, median transfusion volume was 0 (0, 400) vs 400 (200, 800) ml in RR and NRR groups (P < 0.05). No significant difference existed in operative duration, postoperative hospital day or incidence of complications between two groups (all P > 0.05). In cases of total gastrectomy, no significant difference existed in operative duration, postoperative hospital day, median transfusion volume or incidence of complications between two groups (all P > 0.05). In RR group, for the cases treated by D1, D2, D3 and paraaortic lymph node dissection (PAND), there were significant differences in operative duration ((248 ± 71), (271 ± 72), (309 ± 96), (351 ± 103) min), postoperative hospital day ((13 ± 4), (16 ± 12), (18 ± 11), (20 ± 19) days), median transfusion volume (0(0, 500), 0(0, 600), 400(0, 800), 600(200, 1000) ml) (all P < 0.05). But no significant difference existed in incidence of complications (P > 0.05). In RR group, operative duration, postoperative hospital day, median transfusion volume was (315 ± 96) vs (264 ± 66) min, (19 ± 15) vs (15 ± 11) days, 400 (0, 800) vs 0 (0, 400) ml in the patients with and without combined organic resection (all P < 0.05). But no significant difference existed in incidence of complications (P > 0.05).
  
  
  CONCLUSIONS
  As compared with palliative resection, radical resection will not increase surgical trauma. For the cases of radical resection, extent of lymphadenectomy and organic resection increase surgical trauma.
