• W2070045240 abstract "Purpose To evaluate the effectiveness of radiologic placement of uncovered stents for the treatment of malignant colorectal obstruction. Materials and Methods From May 2003 to January 2008, 116 radiologic placements of uncovered stents were attempted in 99 patients (M:F, 59:40; mean age, 65 years) with malignant colorectal obstructions. The location of stent insertion, technical and clinical success, complication rates, and patency rates of the stents in a palliative group were also evaluated. In the palliative group, the follow-up period was 2–455 days (mean, 100 ± 129 days). Results Radiologic stent placement was technically successful in 110 of 116 cases (94.8%). Fifty cases of stent placement were preoperative (45.5%, 50 of 110) and 60 (54.5%, 60 of 110) were performed with palliative intents. In five of six failed cases, the replacement of the stent was later performed with the assistance of colonoscopy. One patient underwent an emergency operation. In 98 of 110 cases, the symptoms of obstruction were relieved, for a clinical success rate of 89.1%. Of the 50 stents that were placed successfully with preoperative intent, 44 patients underwent surgery within a mean of 10.3 days. In the palliative group, the patency rates were 89.7% at 1 month, 85.6% at 3 months, 80.8% at 6 months, and 72.7% at 12 months. Conclusions The radiologic placement of uncovered stents for the treatment of malignant colorectal obstruction is feasible and safe and provides acceptable clinical results not only for preoperative decompression but also for palliative cases, especially in left-sided colonic obstructions.
