3. Results3.1. Characteristics of patients who underwent gastrectomy and gastrojejunostomyThe subjects included 43 men and 13 women. Twenty-nine patients underwent distal gastrectomy or total gastrectomy, whereas 27 patients underwent gastrojejunostomy. All patients had GOO. There were no cases of perforation in this study. Blood transfusion was required preoperatively in 19 patientsd8 in the gastrectomy group and 11 in the gastrojejunostomy group. The median follow-up duration in all patients was 297 days (inter- quartile range, 100.5e408). The 1-year survival and 1-year disease- specific survival rates were 58.0% and 13.7%, and 60.9% and 13.7% inthe gastrectomy and gastrojejunostomy groups, respectively. Long- term survival was observed in the gastrectomy group, with the longest survival time confirmed at 3,648 postoperative days. There was also a case of survival confirmed at 1565 postoperative days and a case of death from other causes confirmed at 1350 post- operative days. Except for tumor depth, no significant difference in clinical characteristics was identified between patients who un- derwent gastrectomy and those who underwent gastro- jejunostomy . The preoperative CCI tended to be higher in the gastrojejunostomy group than in the gastrectomy group, albeit without statistical significance. Surgical outcome, operative time, and intraoperative blood loss were significantly higher in the gas- trectomy group than in the gastrojejunostomy group . A total of 16 complications were observed, all of which were classified as grade II or lower, except in one patient from the gastro- jejunostomy group who underwent surgical intervention for afferent loop syndrome. Postoperative chemotherapy tended to be performed more often in the gastrectomy group than in the gas- trojejunostomy group, albeit without statistical significance.
