    Abstract:
    BACKGROUND: Two types of self-expanding metal stents to palliate dysphagia in patients with unresectable malignant oesophageal strictures have been compared. METHODS: From February 1996 to October 2000, 50 metal stents (23 covered Ultraflex and 27 Esophacoil) were placed in 50 patients (40 males, mean age: 67+/-12 years, range: 33-100, mean dysphagia score: 3.18+/-0.66) with unresectable malignant oesophageal strictures. Patients were followed until death. A retrospective review has been made of a prospectively collected database. RESULTS: The two groups were comparable as far as concerns degree of dysphagia, location and stricture length. Stent placement was successful in all cases. Covered Ultraflex stent was placed in 2 patients with oesophagobronchial fistula. No procedure-related deaths were seen. Early severe complications occurred in 2 patients (perforation in 1 and tumour bleeding in 1, in the Esophacoil group). Nine patients and 1 patient complained of pain following Esophacoil and Ultraflex stent placement, respectively. Late complications were asymptomatic rupture of distal Esophacoil rings in 2 patients, symptomatic Ultraflex stent migration in 2 and tumour overgrowth in 3 (Esophacoil 1, Ultraflex 2). Mean dysphagia score at 4 weeks after stent placement was 1.9+/-0.77. Mean survival was 177+/-109 days (range: 35-603 days). There were no significant differences in technical success, dysphagia palliation, complications (except chest pain) and survival using the two types of stent. CONCLUSIONS: Self-expanding metal stents are safe with high technical success and achieve satisfactory long-term palliation for dysphagia. The covered Ultraflex and Esophacoil stents are equally effective.
