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.
