EsophaCoil for palliation of dysphagia in unresectable oesophageal carcinoma: short- and long-term results.
OBJECTIVE
Few reports have shown that EsophaCoil is an effective and safe prosthesis for palliation of malignant oesophageal dysphagia. A single centre experience using this type of prosthesis is reported.


METHODS
Between January 1995 and September 2000, 42 consecutive patients, 41 with unresectable oesophageal cancer and one with oesophageal stenosis secondary to lung cancer, were treated with 44 EsophaCoils (2 patients received 2 stents). Tumours were located in lower third of oesophagus and/or gastric cardia in 22 cases, in middle third in 18 and in upper third in 2. Mean stricture length was 5.3 cm. Implantation was performed on hospitalized patients.


RESULTS
EsophaCoil placement was successful all 44 times and was followed by complete expansion of the prostheses. There were no major procedure-related complications or deaths. Dysphagia score improved from mean of 2.9 to 1.3 within 24 hours of stent implantation. Median hospital stay was 2.7 days. Late complications occurred in 14 patients (34.2%): 3 migrations into stomach, 7 tissue overgrowth, 2 late perforations and 2 food impactions. Mean survival time was 4.2 months (range 1-10).


CONCLUSIONS
In our experience, full expansion of EsophaCoil was achieved in all cases. This result, was associated with high incidence of retrosternal pain. Relief of dysphagia score was identical to that obtained with other types of Self-Expanding Metal Stent. Coil design prevented tumour ingrowth and allowed retrieval of three migrated stents. Mean survival time was similar to that reported in larger series using different types of Self-Expanding Metal Stent.
