[Efficacy of endoscopic gastroduodenal stenting for unresectable gastric cancer with gastric outlet obstruction]

Abstract

Methods: We performed endoscopic gastroduodenal stenting for gastric outlet obstruction (GOO) caused by unresectable gastric cancer in 15 patients. We compared the clinical outcomes of the stent placement procedure with those of a gastrojejunostomy performed in 32 patients.

Results: Stent placement was performed safely without complications, and the median number of days until oral food intake could be resumed and the median number of days spent in the hospital was 2 and 15 days, respectively. The GOO score improved in 13 patients (87%); however, re-interventions were necessary for 7 patients due to stent obstruction caused by tumor growth. No differences between the stenting and gastrojejunostomy groups were found for the rate of improvement in GOO score, the duration until oral food intake could be resumed, or the overall survival rate. Patients in the stenting group had significantly fewer complications and shorter hospital stay. However, more re-interventions were required for patients of the stenting group compared to patients of the gastrojejunostomy group.

Conclusion: Endoscopic gastroduodenal stenting can be performed safely and is beneficial for the improvement of oral food intake.
