A 45-year-old man was admitted to our department, with the symptoms of gastric outlet obstruction. A gastric adenocancer metastatic to the liver had been diagnosed at an another institute 10 days previously. Endoscopy revealed pyloric obstruction due to advanced carcinoma of the gastric antrum. Abdominal computed tomography showed the gastric malignancy and liver metastases, and no lesions of the small or large bowel. An uncovered, 20 mm × 12 cm, self-expandable metallic stent (Ultraflex; Boston Scientific, Ireland) was deployed without any complication ([Fig. 1] a). The patient began to feed orally the next day, and we referred him to the medical oncology department for evaluation for chemotherapy.

The patient was readmitted with abdominal pain and constipation 7 days after the stent placement. The abdomen was distended with generalized rebound tenderness. Endoscopy excluded stent migration, and upright abdominal radiography revealed gas/fluid levels ([Fig. 1 ] b). At laparotomy, although ascites was absent, he was found to have a tumoral infiltration compressing the ileum ([Fig. 2 ] a). A palliative side-to-side ileo-ileal anastomosis was performed ([Fig. 2 ] b). Histopathological examination of the biopsy specimen taken from the ileal lesion revealed adenocarcinoma. The patient is still alive 45 days after the palliative operation for intestinal obstruction.

Distal gastrointestinal tract obstruction may be concealed in gastric cancer patients with gastric outlet obstruction as these patients cannot feed orally. This case demonstrates the importance of wide investigation for possible tumoral obstruction of the small or large bowel before a duodenal stent is placed for palliation.
