Endoscopic treatment of praecancerous colorectal lesions and early colorectal cancer.

Endoscopic mucosal resection or piece meal polypectomy are the methods of choice for the treatment of unifocal visualized lesion. Thermal ablative techniques are indicated for flat adenomas as a adjunct therapy after an imcomplete EMR or piece meal polypectomy. Photodynamic therapy using ALA photosensitisation is effective in the treatment of multifocal lesions and also in combination with EMR or thermal ablative techniques. At present, the "tailored suite" combination of these techniques for each patient, according to the character of the lesions, is considered to be the most effective treatment of precancerous lesions and early colorectal cancer (Tab. 1, Fig. 2, Ref. 16).
