N2 - Background: Emergency surgery for malignant colon obstruction entails relatively high morbidity and mortality rates and typically necessitates a 2-step resection. These problems might be potentially mitigated by placement of a self-expanding metal stent (SEMS) as a bridge to surgery. A nitinol colorectal SEMS may offer several advantages, but available evidence on the utility of this SEMS type remains highly limited. Objective: Our purpose was to evaluate the effectiveness and safety as a bridge to surgery of a nitinol SEMS designed for colorectal use. Design: Prospective and retrospective multicenter clinical study. Setting: Sixteen European study centers. Patients: Thirty-six patients with malignant colonic obstruction. Interventions: Nitinol colorectal SEMS placement. Main Outcome Measures: Technical success in accurate SEMS placement with coverage of the entire stricture length, clinical success in alleviating colonic obstructive symptoms, and bridging to elective surgery. Results: Technical success was achieved in 97% of patients with a 95% CI of 85% to 100% and clinical success in 81% (95% CI, 64%-92%). Elective surgery was performed in 94% (95% CI, 81%-99%) of patients at a median of 11 days (95% CI, 7-15 days) after SEMS placement. SEMS-related perforation occurred in 3 patients. Limitations: No control group was included in this nonrandomized cohort study. Conclusions: In this first comparatively large clinical study of a nitinol colorectal SEMS as a bridge to surgery, a high proportion of patients successfully proceeded to elective surgery after prior decompression by SEMS placement.
