We evaluated the efficacy of gastrojejunostomy for patients with unresectable gastric cancer. Thirteen patients had undergone gastrojejunostomy (GJ group) and 14 patients who couldn't receive gastrojejunostomy, but had only been observed into their abdomen in the operation (S group). Between two groups, there were no significant differences in the effective rate, median survival time and the number of dates the patient stayed home after the operation. Gastrojejunostomy was useful for patients with a strong case of stenosis in the stomach, and may improve the quality of life as one of the multimodal therapy.
