Summary
EsophaCoil, a self-expandable esophageal metallic coil, effectively treated dysphagia in 96% of patients with malignant esophageal strictures. This study highlights its low complication and migration rates in long-term palliative care.
Area of Science:
- Gastroenterology
- Oncology
- Medical Devices
Background:
- Esophageal and gastric cardia cancers cause progressive dysphagia, often unresectable.
- Surgical resection has risks of recurrence and strictures.
- Existing self-expandable metallic stents have drawbacks like low radial force and migration.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of EsophaCoil, a self-expandable esophageal metallic coil.
- To assess its performance in palliative treatment of malignant esophageal strictures.
Main Methods:
- 84 EsophaCoil stents were placed in 81 patients (mean age 69.8 years) with various esophageal conditions including cancer and benign strictures.
- Patients with bronchoesophageal fistulas were also included.
- Follow-up recorded early and late complications, and dysphagia scores.
Main Results:
- Successful stent placement in all patients, with 96% experiencing dysphagia improvement.
- Bronchoesophageal fistulas were successfully closed in all 5 cases.
- Early complications occurred in 11 patients (3 severe), and late complications in 18 (including migration, breakage, impaction, overgrowth, bleeding).
Conclusions:
- EsophaCoil is effective for palliative treatment of dysphagia from malignant esophageal strictures and fistulas.
- The device demonstrated low malfunction and migration rates.
- No instances of tumor ingrowth were observed.
