[Treatement of colorectal obstruction with self-expanding metallic stents under fluoroscopic guidance].

PURPOSE

To prospectively evaluate fluoroscopic-assisted insertion of self-expanding metallic stents before surgery or for palliative treatment of soft tissue colorectal obstruction. Materials and methods. From January 1999 to October 2000, 18 consecutive patients with colorectal obstruction were included in the study. Treatment with self-expanding metallic stent was either the first line of treatment before surgery (n=8) (group I) or purely palliative (n=10) (group II). Colic stenosis was located proximal to the sigmoid in seven cases.

RESULTS

Technical success was achieved in 83.3% of cases and colic decompression was observed after 48 hours in all patients with a stent. Thirty days mortality and stent related complications were respectively 0% and 37.5% for group I, and 20% and 50% for group II. All complications were minor except for one colic perforation by a guidewire.

CONCLUSION

Stent insertion was effective and provided relief of colic obstruction in the majority of cases. Randomized studies would be necessary to demonstrate a definitive reduction in mortality and morbidity with this technique as compared to the classical surgical approach.
