In the Netherlands, yearly approximately 2100 patients are diagnosed with gas-
tric cancer, 1500 with pancreatic cancer, 400 with hepatobiliary cancer and 90 with
duodenal cancer.1 The median survival of these patients with locally advanced un-
resectable disease is 8-12 months and only 3-6 months for those with metastatic
disease at presentation.2 Gastric outlet obstruction (GOO) is a common symptom in
these patients and it has been found that 10-20% of patients with pancreatic cancer
develop GOO.3−5 GOO causes nausea, malnutrition and dehydration, resulting in a
poor clinical condition at presentation.5−7 Therefore, palliative treatment of GOO
is mandatory as the clinical condition of these patients deteriorates rapidly, with
consequently a short survival if left untreated. The aim of palliative treatment is
to re-establish oral food intake and stabilize or even improve quality of life of these
patients
