In a multicenter pilot study, a prototype bipolar electrocoagulation tumor probe was employed for palliation of obstructing circumferential esophageal cancer in 20 patients. Mean number of initial treatment sessions was 1.7. Dysphagia and tumor channel size improved significantly after treatment Mean treatment interval before repeat treatment was 7.6 weeks. Major complications included delayed hemorrhage (two patients) and esophageal-pulmonary fistula (two patients). This new device may provide a less expensive alternative to laser or surgery for palliation of malignant esophageal obstruction.
