[Short-Term and Long-Term Outcomes as a Bridge to Surgery for Malignant Colonic Obstruction]

We investigated the efficacy of colonic stent as a bridge to surgery(BTS)for malignant colonic obstruction retrospectively. 25 patients were inserted self-expandable metallic colonic stent as BTS(S group), 16 patients were placed trans-anal ileus tube as BTS(I group)and in 15 patients(E group)emergent surgery were performed. These 3 groups were investigated as follows. Technical success for colonic stent placement was obtained in all S group patients but clinical success rate was 92.0%(23/25). One was not decompressed sufficiently due to 2 obstructed colonic cancers and another patient stent was migrated. 3-year overall survival was 79.7%(S group), 75.0%(I group), 73.3%(E group), respectively. 3-year progression- free survival was 47.1%, 56.3%, 53.3%, respectively. Overall survival rate for S group patients was equivalent compared with patients of non-obstructive colonic cancer(control group)in stage Ⅱ/Ⅲ for the same investigation periods. Colonic stent for BTS was indicated to be safe and effective strategy for obstructive colon cancer, and further investigation are needed to confirm long-term outcomes.
