Initial Clinical Experience with Colonic Stent Placement

Background: The purpose of this study is to review initial experience with a colonic stent as an alternative to colostomy in patients with colonic obstruction. Methods: Ten patients diagnosed with acute colonic obstructions from both benign and malignant causes underwent stent placement. Self-expandable metallic stents were deployed using fluoroscopic guidance. Patients were followed up clinically until removal of the stent or death. Results: Nine of the 10 patients who underwent colonic stent placement achieved clinical decompression within 6 hours. Six patients underwent standard mechanical bowel preparation and elective resection of obstructing lesions. The other 4 patients received stent placement for palliative purposes. Complications included 4 cases of migration and 1 death. Migrated stents in the rectum were easily retrieved and replaced using fluoroscopic techniques. There were no perforations. Conclusion: Placement of self-expandable metallic stents for acute colonic obstructions may allow patients to undergo elective surgical resection avoiding possible colostomy.
