Introduction Malignant gastric outlet obstruction can be a distressing medical condition leading to considerable morbidity with a well recognised poor prognosis. Previous studies (mostly outside of the UK) have shown that endoscopic insertion of a duodenal stent can alleviate the obstructive symptoms to good effect (1–3). In 2009, we set up a regional service for duodenal stent insertion with an aim to replicate these results across a UK upper gastro-intestinal cancer network (catchment area 1.4 million).

Methods A retrospective analysis was performed in patients who had an endoscopically placed duodenal stent for inoperable cancer causing mechanical gastric outlet obstruction. We reviewed hospital/endoscopy electronic records regarding patient demographics, length of hospital stay after the procedure, endoscopy re-intervention and survival.

Results Between July 2009 and November 2012 a total of 27 patients underwent duodenal stent (uncovered WallFlex®, Boston Scientific) insertion. 15 were men, mean age of 70.6 years (range 27–86). 23/27 (85%) patients were discharged home after the procedure, 2 were transferred to a hospice and 2 died in hospital. The average length of hospital stay after the procedure was 5.7 days (range 0–25).

Endoscopy re-intervention was performed in 2 patients for stent occlusion requiring further stent insertion. 22 patients have been followed until death with a mean survival period of 12.5 weeks (range 1–34). 5 patients remain alive at the time of abstract submission.

Conclusion Duodenal stent insertion offered a good palliative option in most of our patients. Our patient outcomes compared favourably to previous published studies.
