Background:
Malignant oesophageal obstruction with an advanced disease presents a difficult challenge. A new class of metal stents have been developed to overcome the limitations of existing treatment modalities.
Methods:
We present our first 58 patients, who have been treated with self-expandable metallic stents, using sedation anaesthesia, with fluoroscopic and endoscopic control. Both kinds of stents, covered and uncovered, were applied.
Results:
There was no procedure-related mortality. The immediate relief of dysphagia was 98%. All four oesophageal fistulas were successfully sealed with covered stents. Due to stent migration, tumour overgrowth, or ingrowth, twelve (21%) of the patients needed re-intervention. Restenting or laser therapies were used against recurrent dysphagia.
Conclusion:
The palliation of oesophageal malignant obstruction with metal stents is a rapid, effective, and relatively safe single treatment which can be employed as part of a multimodal treatment program.
