Abstract

Purpose

To evaluate the technical feasibility and clinical effectiveness of fluoroscopic self-expandable metal stent (SEMS) placement in malignant gastroduodenal obstructions after failed endoscopic SEMS placement.

Materials and Methods

Between September 2010 and July 2017, 874 patients underwent endoscopic SEMS placement for dysphagia caused by malignant gastroduodenal obstructions. Endoscopic SEMS placement failed in 55 of 874 patients (6.3%). These patients were referred for fluoroscopic SEMS placement. In case of failed fluoroscopic SEMS placement, combined endoscopic and fluoroscopic SEMS placement was attempted at the same setting.

Results

Fluoroscopic SEMS placement was technically successful in 40 of 55 patients (72.7%). Combined endoscopic and fluoroscopic SEMS placement was technically successful in 6 of 15 patients with fluoroscopic SEMS placement failure. Failures in the nine patients were due to complete obstruction (n = 5) and acute angulation at the stricture site (n = 4). The overall technical success rate was 83.6% (46/55). Clinical success was achieved in 95.6% of patients (44/46). Complications occurred in 7 of 46 patients (15.2%), including tumor overgrowth (n = 3), SEMS migration (n = 3), and bleeding (n = 1). The median SEMS patency and patient survival periods were 515 (95% confidence interval (CI), 266.6–761.5) and 83 (95% CI 60.6–105.4) days, respectively.

Conclusions

Fluoroscopic SEMS placement is technically feasible and clinically effective in cases of endoscopic SEMS placement failure. A combined endoscopic and fluoroscopic approach increases the technical success rate after failure of the endoscopic or fluoroscopic approach.

Level of Evidence

Level IV.
