Abstract

Objective

To investigate the influence of the timing of stent removal on the outcome of temporary stent placement with concurrent chemoradiation therapy in patients with unresectable oesophageal carcinoma.

Methods

Retrospective analysis was performed on 52 patients undergoing temporary stent placement. Stents were electively removed within 4 weeks in 15 patients (group A), 4–6 weeks in 17 patients (group B) and after 6 weeks in 20 patients (group C). Recurrent symptoms after stent removal, dysphagia score and overall survival periods were compared among the groups.

Results

Stent placement and removal were technically successful in all patients. The dysphagia score was significantly improved in all groups (P < 0.001). In 19 patients (36 %), recurrent symptoms occurred 15–441 days after stent removal. In group A, recurrent obstruction was significantly higher than in groups B (P = 0.049) and C (P = 0.019). Incidence of oesophago-respiratory fistulas in group C was significantly higher than in group A (P = 0.027). There was no significant difference in survival periods.

Conclusion

The ideal time for stent removal likely falls between 4 and 6 weeks following the start of palliative CCRT allowing the temporary stents to relieve dysphagia effectively in patients with unresectable oesophageal carcinoma.

Key Points

• Stents are usually required for unresectable oesophageal carcinoma

• Optimal timing of stent removal is 4–6 weeks after starting palliative CCRT.

• Early stent removal (<4 weeks) is associated with higher recurrence rates.

• Delayed stent removal (>6 weeks) is associated with greater oesophago-respiratory fistula development.
