Background: Despite advances in staging methods, surgical techniques, and adjuvant treatment, recurrent cancer after esophagectomy is a major cause of morbidity and mortality.
Objective: Our purpose was to investigate the safety and efficacy of a self-expandable metal stent (SEMS) in patients with dysphagia or fistula caused by recurrent cancer after esophagectomy.
Design: Prospective, observational study with standardized treatment and follow-up.
Setting: Single university center.
Patients: In 81 patients with recurrent cancer after previous surgical esophagectomy, 100 esophageal SEMSs were inserted for dysphagia (n = 66) or fistula formation (n = 15).
Interventions: Stent placement.
Main outcome measurements: Technical and functional outcome, complications, and survival.
Results: The SEMSs restored luminal patency in 65 (98%) of 66 patients and sealed malignant fistulae in 14 (93%) of 15 patients. Stent dysfunction occurred in 24 (30%) of 81 patients. They all were successfully managed by subsequent endoscopic intervention. After stent placement, a total of 16 complications were observed. Major complications occurred in 9 (11%) of 81 patients, mild complications occurred in 7 (9%) of 81 patients. The overall 30-day mortality rate after stent insertion was 25%. Progression of the disease resulted in death after a median interval of 70 days (range 1 day to 91 months).
Limitations: Nonrandomized design.
Conclusions: SEMS placement in recurrent esophageal cancer after surgical resection offers adequate palliation by relieving dysphagia and sealing off esophageal respiratory fistulae. Therefore, in these patients who have a relatively short life expectancy, SEMS placement should be considered the treatment of choice.
