Stenting for obstructing colorectal malignancy: an interim or definitive procedure.
BACKGROUND
The purpose of this paper is to review and report our experience with colorectal stenting in the management of malignant large bowel obstruction.


METHODS
Twelve consecutive patients with malignant left-sided large bowel obstruction between June 1998 and January 2001 underwent insertion of self-expanding metallic stents. One patient required two stents. Eight stents were inserted under fluoroscopic guidance, and five were inserted with combined fluoroscopic and endoscopic guidance. Patients were followed up until death, stent removal or the time of publication.


RESULTS
Thirteen stents were inserted. Eleven patients with acute large bowel obstruction had relief of obstruction with stenting, and one of these patients required a second stent because relief had been incomplete. One patient was stented in order to subsequently close a problematic stoma. Technical success was 92.9% and clinical success was 100%. Three patients proceeded to surgical resection. In nine patients, the stent was left as the definitive procedure. Of these, six patients have died within 4 months. Complications included one case of migration, one case of reobstruction, one intestinal haematoma and one case of cheesewiring.


CONCLUSIONS
Colorectal stenting is an important treatment modality for malignant large bowel obstruction. It may be definitive treatment alone, or a bridge to elective surgical resection.
