Clinical application of duodenal stent placement under gastroscopy and fluoroscopy

Objective: To evaluate the clinical value of duodenal stent placement through the gastroscope combined with fluoroscopy. Methods: 22 patients with malignant gastric outlet or duodenal obstruction were treated with 26 attempts of duodenal stent placement through the gastroscope combined with fluoroscopy. Results: The success rate of the duodenal stent placement was 25/26 (96.15%) in 22 patients. Four patients required repeated stent placement due to stent obstruction or migration with tumor progression. The procedure was unsuccessful on 1 patient with pancreatic cancer because of obstruction of the third part of duodenum. After the procedure, all patients were examined by gastroscopy and fluoroscopy to check the position and patency of the stents. 5 patients had minor bleeding after the procedure. There was no other complication including gastrointestinal perforation. All patients showed relief of obstructive symptoms in 24 hours. The median survival was 7.2 months. Conclusion: Stent placement through the gastroscope combined with fluoroscopy improves the success rate of relieving malignant gastric outlet or duodenal obstruction. (authors)
