| Popis: | OBJECTIVE. This study evaluated the technical feasibility and clinical effectiveness of fluoroscopic stent placement in malignant colorectal obstructions after failed endoscopic stent placement. MATERIALS AND METHODS. Between January 2004 and December 2017, 41 patients with malignant colorectal obstructions were referred for fluoroscopic stent placement after failed endoscopy. The procedures were performed for palliation (n = 35) or as a bridge to surgery (n = 6). The technical and clinical success, complications, stent patency duration, and patient survival were retrospectively analyzed. RESULTS. Fluoroscopic stent placement was technically successful in 38 patients (92.7%). The causes of technical failure were complete obstruction (n = 1), redundant sigmoid colon (n = 1), and colon perforation (n = 1). Clinical success was achieved in 37 patients with technical success (97.4%). Major complications occurred in three patients (7.9%) and included colon perforation (n = 2) and anal pain (n = 1). The six patients with stenting as a bridge to surgery underwent elective colectomy uneventfully (100%). In 32 patients with technically successful palliative stenting, the median primary stent patency duration and patient survival were 353 days (95% CI, 162-353 days) and 335 days (95% CI, 116-335 days), respectively. CONCLUSION. Fluoroscopic colorectal stent placement is technically feasible and clinically effective in most patients with failed endoscopic procedures. |
