  • Title: Insertion of self-expanding metal stents for malignant dysphagia: assessment of a simple endoscopic method.
    Author: Singhvi R, Abbasakoor F, Manson JM.
    Journal: Ann R Coll Surg Engl; 2000 Jul; 82(4):243-8. PubMed ID: 10932657.
    Abstract:
    AIM: To assess the efficacy, safety and long-term results of self-expanding metallic prostheses, placed using an entirely endoscopic method, for the relief of dysphagia in oesophageal carcinoma. PATIENTS AND METHODS: A consecutive series of 50 patients (30 men, 20 women), aged 43-91 years (median, 75 years) underwent stent placement (Ultraflex Stent, Boston Scientific, Watertown, MA, USA) under general anaesthesia without fluoroscopic control. RESULTS: Stent placement was successful in all patients. Swallowing improved from dysphagia score 4, 3 or 2 to score 1 (or 0) in all patients available for long-term follow-up (excluding two patients who died, and two who had resection, in the immediate post-stenting period). There were two early deaths that were, or could have been, procedure-related and one early complication, in addition to technical problems in 6 cases, all early in the series. Seven patients required endoscopic laser treatment, on 13 occasions, subsequently for tumour in-growth or over-growth. Of the 46 patients with long-term stents in situ, 36 patients died with a median survival time of 4 months (range 10 days to 24 months). At the time of writing, 10 patients are still alive with a median survival of 4 months (range 1-11 months). CONCLUSIONS: Self-expanding metallic stents provide rapid, safe and effective relief of dysphagia. They can provide long-term palliation (> 1 year) with endoscopic laser treatment for recurrent in-growing/over-growing tumour. Fluoroscopic control is not necessary for the safe and accurate placement of such stents.
