Background The optimal management of gastric outlet obstruction (GOO) due to gastric cancer (GC) is unclear. We examined the relationships between clinical and management variables and outcomes in patients with GC having GOO. Methods The GOO management and clinical course were reviewed in patients with GC and GOO. Cox regression and Kaplan‐Meier analyses were used to identify variables predictive of overall survival (OS). Results The study included 59 patients. Eleven had imaging evidence of metastasis and 35 had pathologically confirmed peritoneal disease. Initial management included resection in 23 patients, feeding jejunostomy ± decompressive gastrostomy (JT/GT) in 25, surgical gastrojejunostomy in five, and endoscopic intervention in six. Seven patients with initial JT/GT underwent resection after neoadjuvant therapy. Median OS (95% confidence interval [CI]) was 21.4 (0.0‐45.1) months in the upfront resection group (median follow‐up, 14.7 months) and not reached in those with initial JT/GT, neoadjuvant therapy, and later resection (median follow‐up, 26.5 months) ( P  = .18). On multivariable analysis, clinically positive nodes (hazard ratio [HR]: 3.76; 95% CI, 1.17‐12.12; P  = .03), metastasis on CT (HR: 3.97; 95% CI: 1.53‐10.26; P  = .01), and resection (HR: 0.37; 95% CI: 0.17‐0.79; P  = .01) independently predicted OS. Conclusion In GOO due to GC, OS is similar after treatment with upfront resection compared with JT/GT, neoadjuvant therapy, and later resection. Upfront JT/GT may allow patients to tolerate chemotherapy and improve selection for gastrectomy.
