Malignant colorectal obstruction treated by means of self-expanding metallic stents: effectiveness before surgery and in palliation.

Camunez F, Echenagusia A, Simo G, et al.

Abstract:

Purpose:
To determine the effectiveness and safety of metallic stents in the treatment of malignant colorectal obstruction before surgery and for palliation.

Materials and Methods:
Eighty patients with acute malignant colorectal obstruction presumed to be malignant were treated by means of implanting self-expanding metallic stents.

Results:
Stent placement was successful in 70 of the 80 patients and resolved bowel obstruction in 67 patients (96%). Two patients had colonic perforation and developed peritonitis 18 and 24 hours after stent placement; one patient died as a consequence. Thirty-three patients underwent elective surgery after 7 days +/- 3 (SD; range, 4-10 days), and adequate tumoral coverage and cleansing of the colon were observed in all patients. Stent placement was used as final palliative treatment in another 35 patients. Patient follow-up lasted a mean of 138 days +/- 93 (range, 36-334 days). The survival rate for the palliative group was 55% at 3 months, 44% at 6 months, and 25% at 9 months. The estimated primary stent patency rate was 91% at 3 and 6 months.

Conclusion:
Management of colorectal obstruction by using metallic stents was effective and safe, although colonic perforation is a potential complication. In cases of palliation, the method may obviate palliative colostomy.
