Abstract BACKGROUND: Gastroduodenal obstruction due to malignancy can be difficult to palliate. Self-expanding metal stents (SEMS) are gaining acceptance as an effective alternative to surgical bypass. METHODS: Patients not suitable for surgical bypass, with complete gastric outlet obstruction as a result of malignancy, were offered palliation with SEMS from November 2004 to December 2008. The procedure was performed under fluoroscopic guidance and conscious sedation. Data were collected prospectively. RESULTS: Seventy patients underwent SEMS placement (hepatobiliary and pancreatic malignancy, 44; antral gastric carcinoma, 19; other, seven). Follow-up was complete in 69 patients (99 per cent). Technical and clinical success rates were 93 and 95 per cent respectively. Median hospital stay was 2 (range 1-18) days, median survival was 1.8 (0.1-19.0) months, and 87 per cent had improved intake after SEMS placement, as determined by Gastric Outlet Obstruction Severity Score before and after stenting (P < 0.001). Complications included two episodes of minor bleeding. CONCLUSION: The use of SEMS to alleviate complete malignant gastric outlet obstruction in patients with limited life expectancy is successful in re-establishing enteral intake in most patients, with minimal morbidity, no mortality and a short hospital stay.
