AIM: The aim of our retrospective study was to determine
the effectiveness and safety of self-expandable metal
stents in patients presenting with large bowel
obstruction secondary to colorectal cancer (regardless
of the tumour site), in a district general hospital
setting.
METHODS: All patients who had endoscopic
colonic stents insertion for obstructive colorectal
cancer between 2001 and 2005 at our centre were
identified retrospectively from patients~ discharge
database and the unit database. The patients were
divided into the ~palliation group~ where the stents
were inserted to relief symptoms only and the ~bridge
group~ where patients with resectable cancer underwent
colonic stenting as a bridge to improve patient~s
general condition before definite surgery. RESULTS:
Thirty-eight patients were included in the final
analysis. Thirty-three tumours were in the distal colon
and five were in more proximal lesions. Stent insertion
was successful in 35 patients (92%). Overall clinical
success was 71%. All five proximal colonic tumours (13%)
had successful stent insertion. Mortality related to
procedure was 2%, and the average survival in all
patients was 141 days from time of stent insertion.
CONCLUSION: Colonic stent is a safe and effective method
for relief of immediate symptoms of malignant distal and
proximal large bowel obstruction.
