[Colorectal stent: therapeutic alternative for acute obstruction?].
A colorectal obstruction generally requires an urgent approach, both diagnostically and therapeutically. This context and a poor general condition make surgery hazardous. An auto-expansive stent is an effective therapeutic alternative, more often used to remove such a benign or malignant colorectal obstruction. In the latter presentation, the stent allows for the removal of the obstacle and for the establishment of a precise diagnosis before surgery. In the case of an incurable tumour or where removal is contra-indicated, a stent can represent a palliative treatment. Success in terms of re-establishment of perfusion, is about 85%. The most frequently encountered complication is perforation and is an indication for urgent surgery. Migration and obstruction of the stent are less frequent.
