Self-Expandable Metallic Stent Placement in the Palliative Treatment of Malignant Obstruction of Gastric Outlet and Duodenum

BACKGROUND/AIMS: To asses the usefulness of flexible metallic stents in the palliation of malignant obstruction of gastric outlet and duodenum. METHODS: Retrospective review was performed between January 2006 and December 2011 in 30 patients. Thirty consecutive patients with obstruction of the gastric outlet underwent palliative treatment with self-expandable flexible metallic stents. Complications and clinical outcomes were assessed. RESULTS: Twenty-four patients had advanced gastric carcinoma at the antrum and/or pylorus, four patients had obstruction at the pylorus due to pancreas tumours and one patient had duodedum and one patient had gall bladder tumour. Symptoms improved in 82.7% of the patients after the procedure. The improvement in ability to eat using the score system was statistically significant (p<0.001). Tumor ingrowth and/or overgrowth were seen in four patients (13.3%), and a second stent was inserted in these patients. The mean stent patency was 100 days (range, 5 to 410). The mean survival was 120.76+/-38.96 days. CONCLUSIONS: Endoscopic placement of self-expendable metallic stents under fluoroscopy is a safe and effective treatment for the palliation of patients with inoperable malignant gastric outlet obstruction caused by stomach or pancreas cancer.
