[Treatment of digestive tract tumors using the Nd-YAG laser]

The authors submit an account of contemporary possibilities of the application of laser in the endoscopic treatment of some gastrointestinal diseases. They give an account of their own experience with the use of Nd YAG laser, particularly in the treatment of oesophageal tumours, stenotizing tumours of the rectum and with removal of broad-based polyps. Good results were achieved in endophytic types of oesophageal tumours, especially those localized in the middle part and with a length up to 10 cm, and also in recanalisation of stenotizing tumours of the rectum. The laser therapy in these cases was palliative. Curative laser therapy was applied in destruction of broad-based polyps and the results were satisfactory.
