Endoscopic treatment of malignant dysphagia

Palliative endoscopic treatment of dysphagia in patients with inoperable oesophageal cancer includes: dilation, Nd:YAG laser photocoagulation and intubation, used alone or in combination. Such procedures are usually performed on an outpatient basis and are associated with a low rate of morbidity and mortality. From 1978 to 1988, 476 patients (401 males, 75 females) were treated at the Endoscopy division of the National Cancer Institute of Milan for inoperable primary or recurrent malignancies of the oesophagus or cardia or for extra-oesophageal neoplasms causing dysphagia. Dilation was used in 172 cases, Nd:YAG laser photocoagulation in 90, prosthesis insertion in 72, dilation and laser in 97, and prosthesis and laser in 45. Functional improvement was reported in 75% of patients after dilation, in 89% after laser treatment, in 80% after intubation, in 80% after dilation and photocoagulation, and in 89% after laser and intubation. The median duration of dysphagia-free interval was 4 weeks in dilated patients, 6-8 weeks in photocoagulated patients and 20 weeks intubate patients. Overall median survival was 6.2 months. The complication rate was: 1.4% in dilation treatment, 1.4% in laser photocoagulation, and 8.8% in prosthesis intubation. Mortality related to endoscopic treatment was 2.1% (10/476 patients). Relief of dysphagia is one of the most important goals of palliative treatment in patients with inoperable oesophageal neoplasms. Moreover, endoscopic palliation improves the quality of life in the patients, with a low complication rate.
