Radiologic placement of metallic esophageal stents: preliminary experience

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Oncology

Background:

• Malignant esophageal lesions frequently cause strictures leading to dysphagia.
• Palliative treatment options are crucial for improving quality of life in these patients.

Purpose of the Study:

• To evaluate the efficacy of covered, self-expanding metallic stents in managing malignant esophageal strictures.
• To assess the safety and clinical outcomes of this intervention.

Main Methods:

• Ten patients with malignant esophageal strictures and dysphagia underwent stent placement.
• Procedures were performed using fluoroscopic guidance and local anesthesia.
• Esophageal patency was confirmed by barium studies, followed by clinical monitoring.

Main Results:

• Successful stent placement restored esophageal lumen patency in all 10 patients.
• Nine patients could tolerate a normal or near-normal diet post-procedure.
• Complications included one esophageal perforation, two instances of reflux, and one case of asymptomatic aspiration. Two patients required double stents.
• Tracheoesophageal fistula symptoms were relieved in two patients.

Conclusions:

• Covered, self-expanding metallic stents provide a rapid and effective palliative solution for dysphagia caused by malignant esophageal strictures.
• Stent placement significantly improves swallowing function and offers a valuable therapeutic option for symptom management.
