Diseases of sphincter region--in 44,9 per cent (anal fissure in 12,5 per cent; erosive and ulcerous sphincteritis--in 16,9 per cent; internal and external hemorrhoids--in 15,5 per cent). Ulcerous and erosive colitis--in 10,6 per cent, etc. The group of the sixth decade was underlined to be most affected--in 48,5 per cent. The localization of the tumours from the anorectal line up to 30 cm--is in 84 per cent and over 30 cm--in 16%.
