Abstract
We retrospectively analyzed cases with malignant colonic obstruction treated with a Niti-S D-type stent and clarified its usefulness. Colonic stenting was performed in 15 cases (12 palliatively ; 3 preoperatively). Colonic stents were properly deployed in all cases. The mean score using the Colorectal Obstruction Scoring System was 1.3 before stenting and 3.8 after stenting. Patients treated with colonic stenting preoperatively experienced rapid improvement in symptoms and underwent single-stage surgery after stenting. Among patients treated with colonic stenting palliatively, 2 developed colonic re-obstruction as a delayed adverse events during the mean follow-up period of 92 (17-380) days. Four patients received chemotherapy after stenting without adverse events. At present, two types of colonic stents are available under health insurance coverage in Japan. A prospective randomized study evaluating long-term outcomes with the use of these stents is needed.
