Background : Dysphagia secondary to carcinoma of the oesophagus and gastric cardia is the principal symptom requiring palliation in those patients who present with late‐stage disease or who are unfit for surgery. The primary aim of the present study was to determine the safety and efficacy of laser photocoagulation in the palliation of malignant dysphagia. Secondary aims were to look at reasons for failure and predictors of outcome; to determine the most appropriate second line therapy for treatment failures; and to look at the results of treatment for early stage disease. Methods : Sixty‐seven patients treated over a 6‐year period with endoscopic Nd:YAG laser photocoagulation were evaluated and the quality of swallowing assessed before and at intervals after treatment. Results : Ninety per cent of patients achieved successful initial palliation. This was sustained in 76% after 3 months of treatment. Within a month before death 71 % of patients were palliated but 29% required the addition of second‐line treatment to achieve this. Complications were infrequent. There were no deaths attributable to laser treatment. Five of 10 patients treated with radiotherapy developed fibrous stricturing that required endoscopic dilatation. No variables were independently predictive for treatment failure. Six patients with early stage disease experienced prolonged survival. Conclusions : We conclude that laser photocoagulation offers safe and effective palliation of malignant dysphagia in this group of patients and is appropriate as first‐line therapy.
