Palliative Stent Insertion for Acute Malignant Colorectal Obstruction: Long-term Patency and Survival

摘要

Purpose:To investigate the long-term outcome of palliative stent insertion for acute malignant colorectal obstruction.Methods:From May 2009 to February 2015, consecutive patients with acute malignant colorectal obstruction underwent palliative stent insertion in our center. Technical success, clinical success, and long-term outcomes were analyzed retrospectively.Results:A total of 45 patients with acute malignant colorectal obstruction underwent palliative stent insertion. Technical success was achieved in 42 of 45 patients. Clinical success was achieved in 41 of 42 patients. During a follow-up of 5 days to 25 months (mean, 6.94.5 mo), the cumulative 6- and 12-month patency rates were 88.6% and 72.7%, respectively. The cumulative 6- and 12-month survival rates were 60.1% and 14.3%, respectively. The independent predictor of prolonging survival was subsequent chemotherapy after stenting (P=0.017).Conclusion:Palliative colorectal stent insertion can provide a good long-term outcome in patients with malignant colorectal obstruction.
