{Abstract}: Gastrojejunostomy (GJ) is becoming a standard surgical treatment for ameliorating malignant gastric outlet obstruction (MGOO). However, data on the long-term outcomes of MGOO treatment are lacking. This network meta-analysis aimed to compare overall survival (OS) rates and subsequent anticancer treatment outcomes of GJwith other therapies in MGOO.
We searched four electronic databases, including PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials, from inception to August 1, 2022. Studies reporting OS associated with GJ versus other treatments for MGOO were selected. The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome assessed was OS, whereas the secondary outcome was subsequent anticancer treatment. We performed a Bayesian network meta-analysis to produce hazard ratios (HR) and odds ratios (OR) with 95% credible intervals (CrIs).
We identified 24 retrospective studies that included 2473 patients. The studies assessed the outcomes of six treatments to alleviate MGOO. Results showed that GJ (hazard ratio: 0.83, 95% CrI: 0.78-0.88) was the most effective treatment for patients with MGOO, with the greatest surface under the cumulative ranking curve (SUCRA) values (79.9%) versus non-resection, palliative chemotherapy (13.9%) in terms of OS. Similarly, GJ (SUCRA: 46.5%) improved subsequent anticancer treatment requirements, ranking second only to jejunostomy/gastrostomy (JT/GT) (SUCRA: 95.9%).
Our study demonstrates that GJ improves OS and follow-up treatments versus other non-resection treatments in patients with MGOO. These findings may serve for selecting appropriate therapy for MGOO.
