The case reports of 40 patients with obstructive esophageal cancer treated
with electrofulguration (EF) or neodymium (Nd)-YAG laser were reviewed.
Surgery was contraindicated because of advanced carcinoma (17 patients),
recurrence after resection (13 patients), recurrence after irradiation
(four patients), and poor medical condition (four). Two patients refused
surgery. There were 31 men and four women; mean age was 62 years. There
were 31 adenocarcinomas, eight squamous cell carcinomas, and one metastatic
breast carcinoma. Tumor locations were lower esophagus in 35 patients,
middle esophagus in three, and cervical esophagus in two. Thirty-five
patients had obstructions; two, bleeding, and three, both. None of the
patients could swallow solids. A total of 255 treatments were given (mean,
6.6 per patient). The mean number of Nd-YAG treatments was 1.9; for EF,
1.3. All 40 patients tolerated solid food after treatment and the esophagus
remained open from three to 14 weeks. Mean survival from first treatment
was 11 months; from diagnosis, 17 months. Both techniques were safe and
effective.
