Endoscopic stenting versus gastrojejunostomy for palliation of malignant gastric outlet obstruction.

The aim of the present study was to analyze endoscopic stenting versus gastrojejunostomy of malignant gastric outlet obstruction (GOO). A systematic review of the literature was undertaken to analyze clinical trials on GOO. Six studies were eligible for analysis (three randomized control trials and three controlled clinical trials). Technical success (OR [95% CI]: 0.10 [0.02, 0.47]; I(2) = 0%; P = 0.003) and minor complications (OR [95% CI]: 0.28 [0.10, 0.83]; I(2) = 49%; P = 0.02). Time to oral intake and length of survival were also shorter in the endoscopic stenting (ES) group. There was no statistically significant difference in clinical success, length of survival, mortality and major complications. The present review demonstrated potentially improved quality of life in the ES group. ES is a safe and effective, minimally invasive and cost-effective option for palliation of malignant gastric outlet obstruction. The present review provides supportive evidence that ES should be considered as the gold standard treatment for malignant GOO.
