Survival curve of 43 patients with incurable gastric cancer with outlet obstruction. ( a ) Overall survivals after gastrojejunostomy and palliative distal gastrectomy. Overall survival did not differ between the gastrojejunostomy and palliative distal gastrectomy groups (P = 0.73). ( b ) Overall survivals of patients with and without postoperative chemotherapy. Patients with postoperative chemotherapy had significantly better survival than those without (P <0.0001). ( c ) Overall survivals of patients with and without postoperative complications. Patients who had postoperative complications had significantly worse survival than those who did not (P <0.0001).
