Summary

Endoscopic mucosal resection and piece meal polypectomy are methods of choice in broad based unifocal rectosigmoideal lesions. Thermal ablative modalities are indicated for flat adenomas, lateral spreading tumors and as an adjunct therapeutic modality for incomplete polypectomy. Photodynamic therapy using ALA photosensitiser is effective in the treatment of multifocal lesions either alone or in a combination with thermal ablative techniques. At present “tailored suite” combination of these techniques for each patient according the character of the lesion is considered to be the most effective treatment for rectosigmoideal praecancerous lesions and early cancer.

Key words:
praecancerous lesions – early cancer – resection – ablation – combination techniques
