- W3084294890 abstract "Self-expandable metallic stent (SEMS) is widely used for malignant colorectal obstruction. Recently, SEMS has been used for palliative option for colorectal obstruction caused by extracolonic malignancy (ECM).To evaluate the efficacy of SEMS for colorectal obstruction caused by ECM, and to identify the factors associated with stent occlusion.Seventy-two patients who were treated with uncovered SEMS insertion for malignant colorectal obstructions caused by colorectal metastasis or peritoneal seeding of ECM at Samsung Medical Center between April 2012 to March 2016 were enrolled. We analyzed technical and clinical outcomes of stent insertion, the factors associated with stent occlusion and long term outcomes after stent insertion.Technical success rate was determined as 90.3% with a clinical success rate of 87.7%. Stent occlusion developed in 28.1%, with a median duration of 51 d. Further, 81.3% with stent occlusion could be treated with secondary stent insertion. Clinical failure was observed to be related to the male sex (P = 0.020) and right colon obstruction (P = 0.017). Stent length ≤ 10 cm was found to be associated with stent occlusion (P = 0.003). Median survival time after stent insertion was 4.7 mo and 40.4% were able to receive their oncological treatments after stent insertion without surgery.Uncovered SEMS is effective for the treatment of colorectal obstruction caused by ECM, considering life expectancy of patients with ECM." @default.
