BACKGROUND: Obstruction is a common complication of advanced colorectal cancer. Stent insertion can reduce the need for emergency surgery and allows chemotherapy to begin immediately. AIMS: To evaluate the technical and clinical success and long-term outcome of stent placement in the management of acute malignant colorectal obstruction. METHODS: From July 2002 to April 2005, 29 self-expanding metal stents were placed in 24 patients (13 men, mean age 67 years, range 36-83). Stents were inserted under endoscopic and fluoroscopic control. Patients were clinically and endoscopically followed up. RESULTS: Twenty-eight out of 29 stents were successfully placed (96.5%) in 23 out of 24 patients with 25 strictures. The clinical success rate was 95.8% (23/24). Two early stent migrations were observed in two patients (8.3%). Late complications developed in eight patients (33.3%) after a median of 3.8 months (range <1-8.6): two migrations and six occlusions. The median survival was 9.8 months (range <1-27). Eleven patients (45.8%) died from progressive disease without any clinical evidence of recurrent obstruction. CONCLUSION: Stent placement is safe and effective. Stent complications are frequent but not life-threatening, and are easy to manage. An improvement in stent design and well-scheduled follow-up are needed in order to prevent such complications.
