    Abstract:
    Palliative therapy for obstructing esophageal carcinoma is more often necessary than curative surgery. The neodymium:yttrium-aluminum-garnet laser was used for vaporization of obstructing esophageal carcinoma in 18 patients requiring 24 treatments. Three women and 15 men (age range 42 to 87 years) had esophageal carcinoma (seven squamous cell and nine adenocarcinoma). Twelve tumors were at the esophagogastric junction, four at the midesophagus, and two in the cervical esophagus. Lengths varied from 3 to 7 cm. Inoperability was due to diffuse metastases in eight patients, local invasion in five, poor operative risk in one patient, and patient refusal for operative treatment in four patients. Energy use was 1000 to 22,600 J per session (mean 6120 J). Good results were achieved in 16 patients (88.9%): Seven returned to full diet, five to soft diet, and four to full fluids without dysphagia. Four patients required retreatment 1 to 3 months later because of recurrent dysphagia. One patient was not benefited by the treatment and died of carcinomatosis 1 week later. No intraoperative complications occurred. Postoperatively, one patient had laryngeal edema and another had a bronchoesophageal fistula 3 weeks later. The mean survival time is 3 1/2 months. Neodymium:yttrium-aluminum-garnet laser vaporization for obstructing esophageal carcinoma is effective palliation regardless of histologic tumor type. It can be performed under direct vision with a low frequency of postoperative complications.
