Comparison of gastrojejunostomy to endoscopic stenting for gastric outlet obstruction: An updated Systematic Review and Meta-analysis.

BACKGROUND

This study aimed to determine the optimal intervention modality for malignant GOO by comparing clinical outcomes after Gastrojejunostomy and endoscopic stenting.

METHODS

Two authors independently searched Web of Science, PubMed, Embase, and the Cochrane Library for articles before February 2021 to compare the clinical outcomes of GOO patients undergoing GJ or ES.

RESULTS

This meta-analysis included 31 articles with 2444 GOO patients. Although the GJ group outperformed the ES group in technical success (OR,3.79; P = 0.003), clinical success was not significantly different between the two groups (OR,1.25; P = 0.50). The GJ group had a longer hospitalization, lower re-obstruction and lower reintervention. Moreover, GJ had a better survival than ES in the gastric cancer group (HR, 0.33; P = 0.009). However, no significant statistical difference was observed in the pancreatic cancer group (HR, 0.55; P = 0.159).

CONCLUSIONS

Both GJ and ES are safe and effective intervention modalities for malignant GOO. GJ had significantly improved survival in gastric cancer patients with GOO, while no significant difference was observed between the two groups in pancreatic cancer patients with GOO.
