title: [Efficacy of endoscopic gastroduodenal stenting for gastric outlet obstruction caused by unresectable gastric cancer].
abstract: BACKGROUND
  In this retrospective study, we investigated the clinical outcomes of endoscopic gastroduodenal stenting (EGDS) for gastric outlet obstruction( GOO) caused by unresectable gastric cancer( UGC).
  
  
  METHODS
  A retrospective study was performed on 20 UGC patients with GOO between 2007 and 2012. We compared the clinical outcomes of EGDS using the WallFlex stent( GDS group, n=8) and palliative Roux-en-Y gastrojejunostomy( RYGJ group, n=12).
  
  
  RESULTS
  The numbers of patients with a poor performance status and prior use of chemotherapy were higher in the GDS group than in the RYGJ group. No postoperative complications were observed, and the GOO score improved in both groups. The median days taken to resume oral food intake, the median duration of oral food intake, and the median survival time in the RYGJ and GDS groups were 4 and 3 days( p=0.0008), 301 and 151 days( p=0.0698), and 345 and 161 days (p=0.0070), respectively.
  
  
  CONCLUSIONS
  EGDS for GOO caused by UGC can be performed safely even after chemotherapy and is beneficial in terms of improvement of oral food intake.
